Abstract

PROBLEM TO BE SOLVED: To realize a game with higher operability using a touch panel.
In parallel with inputting a movement operation of a player character 2 with a direction input key 1402, an attack operation is input with a touch panel 1409. When a sliding operation is performed on the touch panel 1409 so as to draw a trajectory 8 surrounding the enemy character 4 displayed on the screen, the enemy character 4 surrounded by the trajectory 8 is automatically registered as a lock-on target. Thereafter, even if the player is moving, as long as the player character 2 or the vicinity thereof is tapped with the stylus pen 1416, the player character 2 moves and automatically performs a shooting operation with the enemy character 4a to be locked on as a target.

Description

  The present invention relates to a program or the like for displaying a battle image between a player character and an enemy character on a display screen to execute a battle game.

  A portable game device having a touch panel as a pointing device on a display screen, such as a Nintendo DS (registered trademark) game machine manufactured by Nintendo, is known. In such a portable game device, a game using a touch panel for operation input is gaining popularity from users because it can perform more intuitive operation input than a game in which operation input is performed only by button operation.

For example, a player character movement operation is input using a pointing device, and an attack is made by performing a slide operation (an operation performed by rubbing the touch panel on the display screen) on the touch panel at a predetermined speed or higher for a predetermined length or longer. What inputs operation is known (for example, refer to patent documents 1).
JP 2006-325695 A

  If a pointing device such as a touch panel is used for operation input, it is possible to obtain an intuitive operation input. However, if most of the player character's operation input is assigned to the pointing device, the game setting may There is one aspect that makes it difficult to quickly operate the player character.

  For example, in a situation in which a plurality of enemy characters approaching while firing bullets toward a player character appear, both operations cannot be input simultaneously if the player character's movement operation and attack operation input are set on the touch panel. In other words, since it is impossible to coordinate the movement and attack such as “attack the enemy while avoiding the movement of the attack from the enemy” in such a situation, it is more difficult to clear the situation than it looks.

  In addition, a so-called “lock-on attack” that automatically tracks and attacks specific enemies well-known in shooting games, etc., is selected and executed from a plurality of attack types (for example, attacks with different attack attributes and ranges) In this case, as the attack operation input, three operations, that is, an attack target selection operation, an attack type selection operation, and an attack timing operation input must be performed by a touch operation. End up.

  The present invention has been made in view of such circumstances, and an object of the present invention is to realize a game with higher operability using a touch panel. More preferably, it is possible to reduce the trouble of the attack operation input accompanying the lock-on attack that requires the selection of the attack type, and realize both the movement operation input and the attack operation input with higher operability.

[First Embodiment]
Next, as a first embodiment to which the present invention is applied, an action game is played on a portable game device in which a touch panel is mounted on a liquid crystal display seen in a portable game device “Nintendo DS (registered trademark)” manufactured by Nintendo Co., Ltd. An example of playing will be described.

[Configuration of game device]
FIG. 1 is an external view for explaining a configuration example of a portable game device. A portable game apparatus 1400 according to this embodiment includes a direction input key 1402 and a button switch 1404 for a player to input a game operation, a first liquid crystal display 1406, a second liquid crystal display 1408, a speaker 1410, and a control unit. 1450 is provided in a flip-flop type apparatus main body 1401 that can be opened and closed by a hinge 1414. Touch panels 1407 and 1409 that can input arbitrary positions on the display screen by touching with a stylus pen 1416 or the like are mounted on the surfaces of the first liquid crystal display 1406 and the second liquid crystal display 1408, respectively.

  Further, the apparatus main body 1401 is provided with a memory card reader 1418 capable of reading and writing data from and to a memory card 1440 that is a computer-readable information storage medium. The memory card 1440 stores programs and various setting data necessary for the control unit 1450 of the portable game apparatus 1400 to execute various arithmetic processes related to game play. In addition, the apparatus main body 1401 is provided with a built-in battery, a power button, a volume control button, and the like which are not shown.

  The touch panels 1407 and 1409 cover almost the entire display screen of the first liquid crystal display 1406 and the second liquid crystal display 408 without shielding the display screen, respectively, and the stylus pen 1416 feels as if the player touches what is displayed on the screen. When touched with (or a finger or the like), the contact position coordinates in the orthogonal Xt, Yt axis coordinate system with the upper left as the origin can be output to the control unit 1450.

  The control unit 1450 corresponds to a control board of the game apparatus, and includes various microprocessors such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), a VRAM, and the like. Various IC memories such as RAM and ROM are installed. In addition, signals from the wireless communication module 1412, the triaxial acceleration sensor 1422, the driver circuit of the first liquid crystal display 1406 and the second liquid crystal display 1408, the driver circuit of the touch panel 1407 and the touch panel 1409, the direction input key 1402, and the button switch 1404. A so-called I / F circuit (interface circuit) such as a receiving circuit, an amplifier circuit for outputting an audio signal to the speaker 1410, and a signal input / output circuit to the memory card reader 1418 is mounted. Each element mounted on the control unit 1450 is electrically connected via a bus circuit so that data can be read and written and signals can be transmitted and received.

  The 3-axis acceleration sensor 1422 detects accelerations in the X-axis, Y-axis, and Z-axis directions orthogonal to detect the attitude change or position change of the portable game apparatus 1400, and sends the detection signal to the control unit 1450. Output. In addition, it is good also as a structure provided with a gyro sensor as a function addition instead of an acceleration sensor. Alternatively, if a change in position or orientation is detected with reference to geomagnetism, it can be replaced by a magnetic sensor.

  The control unit 1450 reads out the program and data stored in the memory card 1440 by the memory card reader 1418 and temporarily stores them in the IC memory to be mounted. Then, the read program is executed to execute arithmetic processing, and each part of the portable game device 1400 is controlled in accordance with operation inputs from the direction input key 1402, button switch 1404, touch panel 1407 and 1409, and an action game is played. Execute.

  In the present embodiment, the portable game device 1400 is configured to read out necessary programs and various setting data from the memory card 1440, but via the wireless communication module 1412, the Internet, LAN (Local Area Network), WAN ( It is also possible to connect to a wired / wireless communication line 1 such as a Wide Area Network and download from an external device.

[Outline of game and operation input method]
FIG. 2 is a diagram showing a game screen example and a basic operation input example in the present embodiment. In the present embodiment, a game space is formed in the three-dimensional virtual space, and the player character 2 and the enemy character 4 are arranged in the game space. Various information displays are combined with an image (so-called 3DCG) obtained by photographing the state with a virtual camera and displayed on the second liquid crystal panel 1408 as a game screen. The virtual camera automatically controls movement, rotation, shooting angle of view, etc. so that the player character 2 is caught near the center of the screen.

  In the action game of the present embodiment, the player character 2 is a battle game in which a gun is used to attack and destroy the attacking enemy character 4. The game is cleared if all the enemy characters 4 that have been prepared are defeated, and the game is over when the strength value is subtracted by the enemy attack and becomes “0”.

The enemy character 4 is automatically controlled to perform a long-range attack in which the bullet 6 is fired toward the player character 2 from a long distance and a close-by attack with a body hit.
The player inputs the movement operation of the player character 2 from the direction input key 1402 to dodge the body of the enemy bullet 6 or the enemy character 4 and, at the same time, taps the enemy character 4 that he wants to attack. The touch panel 1409 is tapped with the pen 1416 to input an attack operation of “standard attack”. The player character 2 is controlled to move at a predetermined speed in the input direction made by the direction input key 1402 and controlled to shoot as many times as tapped in the tapped direction.

  As described above, in this embodiment, the movement operation input of the player character 2 is assigned to the direction input key 1402 and the attack operation input is assigned to the touch operation on the touch panel 1409. Therefore, the movement operation input and the attack operation input are performed in parallel. Can be done. In other words, the movement control can be performed regardless of whether or not the attack control of the player character 2 is being performed. Accordingly, it is possible to perform a linked operation of movement and attack such as “attack the enemy while avoiding the movement of the attack from the enemy (the body of the bullet 6 and the enemy character 4)”.

  Further, in this embodiment, attention is paid to where the player plays from the viewpoint on the game screen, and a device that facilitates parallel input of movement operation input and attack operation input is an operation input related to special attacks. It is included.

  3 to 6 are conceptual diagrams for explaining the attack operation input of the “first type lock-on attack” which is the first special attack in the present embodiment and the attack action of the player character 2 corresponding to the attack operation input. FIG.

  As shown in FIG. 3, the player performs an attack target selection input as a first element of the attack operation input. Specifically, the enemy character 4 (4a to 4d in the example in the figure) displayed on the screen with the stylus pen 1416 is moved so as to rub on the touch panel while maintaining the touch state on the touch panel 1409. Then, slide operation is performed so as to draw a locus of a substantially circular closed curve shape. Then, the enemy character 4 within the range surrounded by the locus 8 drawn by the slide operation (the enemy character 4a at the leftmost end of the screen in the example in the figure) is registered as a target for automatic tracking attack, so-called lock-on target. .

  As shown in FIG. 4, the enemy character 4a registered as a lock-on target is changed to a special display form different from the other enemy characters 4b, 4c, and 4d, and is clearly indicated to the player as a lock-on target. The The special display mode can be realized, for example, by appropriately setting differences such as display color, luminance, brightness, outline emphasis, blinking, enlargement / reduction, and addition of markers such as arrows. In the example shown in the figure, a lock-on marker 10 that gives a yellow outline to the outer periphery of the enemy character 4a registered for lock-on is given.

When the lock-on target is registered, the first type lock-on attack becomes possible.
The player taps a predetermined first-type lock-on attack operation input determination area 12 centered on the player character 2 with the stylus pen 1416 in the manner of tapping the player character 2 as a second element of the attack operation input. An attack instruction operation, that is, an attack timing is input. Then, whether the player character 2 is moving or stopped, the movement of the player character 2 is automatically controlled so as to aim at the enemy character 4a registered as a lock-on target. For example, in FIG. 4, since it is in a critical situation where the hand to the enemy characters 4 c and 4 d is blocked, the player character 2 is moving while being moved to make a U-turn, but the player character 2 automatically moves his arm. In turn, the movement is controlled so as to attack the enemy character 4a to be locked on.

It should be noted that the viewpoint of the player is directed to one point of the player character 2 regardless of the movement operation input or the attack operation input.
As shown in the figure, in a crisis situation where the hand to the enemy is blocked, the priority should be to avoid the movement of the player character 2 from the enemy attack. On the other hand, if the attack is neglected, it will be a crisis. The situation cannot be overcome. At this time, in the attack operation input in which the attack target is touched and specified as in the standard attack described above, the move operation input is performed while alternately changing the line of sight for both the player character 2 and the movement of the enemy character 4 as the attack target. And attack operation input. Even if the movement operation input is assigned to the direction input key 1402 and the attack operation input is assigned to the touch operation on the touch panel 1409, the difficulty level becomes high.

  However, in the first type lock-on attack of the present embodiment, if the enemy character 4 to be attacked is specified by surrounding it with the locus 8 in advance, the player character 2 is tapped in the manner of lightly tapping the attack operation input. As long as the attack timing is input, the player character 2 can automatically follow the lock-on target enemy character 4a even while moving. That is, since the player can perform the movement avoidance operation and the attack operation while fixing the viewpoint to the player character 2 (while paying attention to the player character 2), high operability can be realized. Therefore, even if it is a critical situation for viewing, an exhilarating play is possible, such as defeating and fighting back.

In the present embodiment, in consideration of the game balance, there is a certain limitation on the use of special attacks that realize such high operability.
Specifically, as shown in FIG. 3, in the present embodiment, a first type lock-on attack gauge 14 that represents the length or number of times that the first type lock-on attack is possible is indicated by the length of the bar. . The state where the bar (hatched portion) with the left end fixed is extended (displayed) to the right end is the maximum value, and the attackable time or number of times is conceptually displayed as the length of the bar (hatching). The white part corresponds to digested.

  The gauge value represented by the first-type lock-on attack gauge 14 is automatically subtracted as the first-type lock-on attack fires, and the hatched portion according to the subtraction result as shown in FIG. 4 gradually. The display is updated to be shorter. When the gauge value becomes “0”, the hatched portion disappears and the first type lock-on attack cannot be continued any more. On the other hand, the gauge value is automatically added while the game play continues and is recovered with time. Therefore, even if the type 1 lock-on attack is performed and the gauge value is reduced to near “0”, the gauge value is recovered by taking a time during which the type 1 lock-on attack is not performed, and the first type lock-on is performed again. An on-attack is possible.

  In the present embodiment, even if the enemy character 4 is registered as a lock-on target, a special attack is not executed unless the attack timing input of the attack operation input is performed, and the gauge value of the first type lock-on attack gauge 14 Will not decrease.

  The registration as a lock-on target is automatically canceled when a touch operation other than the first-type lock-on attack operation input determination area 12 or when a predetermined time (for example, 7 seconds) elapses from the start of registration.

  FIG. 5 shows a case where a plurality of enemy characters 4 are set as lock-on targets in the first type lock-on attack. As shown in the figure, when a trajectory 8 is drawn so as to surround the enemy character 4a and the enemy character 4b, they are equally registered as lock-on targets.

  When the attack timing input, which is the second element of the attack operation input, is entered, as shown in FIG. 6, either one of the enemy characters 4a and 4b to be locked on is automatically selected as the attack target (target), and the player The character 2 is controlled so as to automatically shoot the attack target. Then, when a certain attack (for example, determination may be made by the number of times of shooting or the accumulation of attack time) is performed, the attack target is automatically switched. At this time, the enemy character 4 selected as the attack target (the enemy character 4a in the example in the figure) is provided with a target marker 16 having a special display form different from the lock-on marker 10, and the player character 2 attacks which one. It is clearly shown whether to do it.

  7 to 8 are conceptual diagrams for explaining the attack operation input of the “second type lock-on attack”, which is the second special attack in the present embodiment, and the attack action of the player character 2 corresponding thereto.

  As shown in FIG. 7, the cross trace 18 is drawn on the touch panel 1409 so that the player cuts the enemy character displayed on the screen with the stylus pen 1416 as the attack target selection input of the first element of the attack operation input. Then, the enemy character 4 (enemy character 4b in the example in the figure) located at the intersection of the crosses is registered as an automatic tracking target, so-called lock-on target.

  As shown in FIG. 8, a lock-on marker 10 is given to the enemy character 4b registered as a lock-on target. When the lock-on target is registered, the second type lock-on attack becomes possible.

  The second type lock-on attack is automatically activated as soon as a lock-on target is registered. An attack operation input (specifically, an attack timing input as the second element) such as a touch operation on the first type lock-on attack operation input determination area 12 as in the first type lock-on attack is not required. When the second type lock-on attack is activated, the number of attacks is automatically continued until the predetermined upper limit value is reached without inputting the attack timing as in the first type lock-on attack. Incidentally, the first type lock-on attack gauge 14 does not change.

  The second type lock-on attack is a special attack with an increased attack power as a price that the player character cannot move. When the second type lock-on attack is activated, the player character 2 stops on the spot and does not accept the movement operation input by the direction input key 1402. However, the enemy character 4b to be locked on with the two handguns is usually fighting with one handgun. The attack power is doubled.

  However, for the registration of lock-on targets, an attack operation input of the first type lock-on attack (specifically, an attack target selection input that is the first element) or a touch operation of an attack operation input of the standard attack was performed. In this case, it is automatically released and the second type lock-on attack is stopped.

  It should be noted here that in order to activate the second type lock-on attack, it is only necessary to draw a cross with a stylus pen 1416 on any enemy character to be attacked. The first type lock-on attack requires two operation inputs, that is, an attack target selection operation input and an attack operation input, as the operation input related to the attack.

  As described above, according to the present embodiment, both the attack type selection and the attack target selection operation can be performed depending on the type of trajectory drawn at the time of the touch operation, so that the attack operation input can be performed efficiently.

  In this embodiment, the movement of the player character 2 is prohibited during the second type lock-on attack. However, the movement speed is slowed down, and the movement and stop are performed intermittently to improve the total movement performance. Of course, it may be configured to be lowered.

  Further, the first type lock-on attack gauge 14 may be similarly used in the second type lock-on attack. In other words, every time a type 2 lock-on attack is fired, the gauge value of the type 1 lock-on attack gauge 14 is subtracted, and when the gauge value becomes “0”, the type 2 lock-on attack can no longer be continued. To.

  Needless to say, the number of types of special attacks is not limited to two, and more types can be set as appropriate. Further, the types of trajectories drawn by touch operations corresponding to these types of special attacks are not limited to circles and crosses as in the above example. For example, a triangle, a star, or the like can be set as a trajectory type corresponding to a circle, and a letter, a spiral, or a T-shape can be set as a trajectory type corresponding to a cross. In addition, it is possible to set a straight line or a curve including a line in the trajectory type. In this case, it is preferable to set an enemy character with such a line (an intersection of the line and the character display image on the display screen) as an attack target.

[Description of functional block]
Next, a functional configuration for realizing the above-described features will be described.
FIG. 9 is a functional block diagram illustrating an example of a functional configuration according to the present embodiment. As shown in the figure, the present embodiment includes an operation input unit 100, a processing unit 200, a sound output unit 350, an image display unit 360, a communication unit 370, and a storage unit 500.

  The operation input unit 100 outputs an operation input signal to the processing unit 200 in accordance with various operation inputs made by the player. In the present embodiment, a direction input unit 102 and a contact position detection unit 104 are included.

  The direction input unit 102 includes a button switch, a joystick, a touch pad, a trackball, a multi-axis detection type acceleration sensor having two or more detection axes, or a single axis detection type acceleration sensor unit combined with different detection axis directions. Also, it can be realized by a multi-directional detection type inclination sensor that enables at least two detection directions or a single direction detection type inclination sensor unit combined with different detection directions. In FIG. 1, the direction input key 1402 and the triaxial acceleration sensor 1422 correspond to this.

  The contact position detection unit 104 is a device that can detect a contact position to the display screen range. The touch panels 1407 and 1409 in FIG. 1 correspond to this.

And a lock-on attack operation control unit 222.

  The contact operation input position acquisition unit 212 determines the corresponding position coordinates in the game screen coordinate system based on the position coordinates detected by the contact position detection unit 104. That is, the coordinates of the touch position on the touch panel 1409 in the game screen coordinate system are obtained.

  The trajectory type determination unit 214 determines the type of the trajectory shape drawn by the contact operation based on the time transition of the position coordinates detected by the contact position detection unit 104. The types of trajectory shapes that can be determined include a plurality of types including at least “circular” and “cross”. The determination method can be realized in the same manner as character input or graphic input using a known touch panel. Accordingly, the trajectory shape dictionary data 504 is stored in advance in the storage unit 500 as the trajectory shape type determination dictionary data.

  The lock-on target registration unit 216 extracts a lock-on target from the enemy characters 4 displayed in the game screen according to the type of the trajectory shape determined by the trajectory type determination unit 214, and extracts the extracted enemy character. Identification information (ID) is stored and registered in the storage unit 500 as the lock-on target character ID 530.

Further, when it is determined that the specific position can be obtained by an intersection or a bending point such as a cross, a cross, a T character, or a point, the enemy character 4 displayed at the specific position in the game coordinate system is extracted. And register. Of course, the extraction method is not limited to these, and may be, for example, the enemy character 4 displayed within a predetermined range of the outer periphery of the specific area. Further, if the determined trajectory type is an arc, The enemy character 4 displayed so as to be arced may be extracted.

  The target selection unit 218 selects an enemy character that is automatically tracked as an actual attack target from the enemy characters registered by the lock-on target registration unit 216, and stores identification information of the selected enemy character in the target character of the storage unit 500. It is stored in ID 532 and registered. Note that the selection method when there are a plurality of lock-on targets may be random selection using random number generation processing, or the registered enemy characters may be cyclically selected in the order of registration.

  The enemy character display form control unit 220 performs control so that the enemy character registered as the lock-on target and the enemy character selected as the attack target are displayed in a special display form in order to clearly show to the player. In the present embodiment, processing related to the provision of the lock-on marker 10 and the target marker 16 corresponds to this.

  The lock-on attack motion control unit 222 controls the position and orientation of the hand holding the gun so that the player character 2 automatically targets the object selected by the target selection unit 218 while the special attack is activated. To do.

  The sound generation unit 250 is realized by a processor such as a digital signal processor (DSP) or a voice synthesis IC, or an audio codec capable of playing back an audio file, for example. Based on the processing result of the game calculation unit 210, sound effects and BGM related to the game Then, sound signals of various operation sounds are generated and output to the sound output unit 350.

  The sound output unit 350 is realized by a device that outputs sound effects, BGM, and the like based on the sound signal input from the sound generation unit 250. In FIG. 1, the speaker 1410 corresponds to this.

  The image generation unit 260 is realized by, for example, a processor such as a GPU (Graphics Processing Unit) or a digital signal processor (DSP), a program such as a video signal IC or a video codec, an IC memory for a drawing frame such as a frame buffer, or the like. The image generation unit 260 generates one game image in one frame time (1/60 second) based on the processing result by the game calculation unit 210, and outputs an image signal of the generated game image to the image display unit 360. .

  The image display unit 360 displays various game images based on the image signal input from the image generation unit 260. For example, it can be realized by an image display device such as a flat panel display, a cathode ray tube (CRT), a projector, or a head mounted display. In FIG. 1, the first liquid crystal display 1406 and the second liquid crystal display 1408 correspond to this.

  The communication control unit 270 executes data processing related to data communication, and realizes data exchange with an external device via the communication unit 370.

  The communication unit 370 is connected to the communication line 1 to realize communication. For example, it is realized by a wireless communication device, a modem, a TA (terminal adapter), a cable communication cable jack, a control circuit, and the like, and the wireless communication module 1412 of FIG. 1 corresponds to this.

  The storage unit 500 stores a system program for realizing various functions for causing the processing unit 200 to control the portable game device 1400 in an integrated manner, a game program necessary for executing the game, various data, and the like. . Further, it is used as a work area of the processing unit 200, and temporarily stores calculation results executed by the processing unit 200 according to various programs, input data input from the operation input unit 100, and the like. This function is realized by, for example, an IC memory such as a RAM and a ROM, a magnetic disk such as a hard disk, and an optical disk such as a CD-ROM and DVD. In FIG. 1, this corresponds to an IC memory or a memory card 1440 mounted on the control unit 1450.

  In the present embodiment, the storage unit 500 stores a system program 501 and a game program 502. When the processing unit 200 reads and executes the game program 502, the function as the game calculation unit 210 can be realized in the processing unit 200.

  The storage unit 500 stores trajectory shape dictionary data 504, game space initial setting data 510, and character initial setting data 512 as data prepared in advance.

  Furthermore, as data that is generated and updated as the game progresses, character status data 514, standard attack flag 516, first type lock-on attack flag 518, second type lock-on attack flag 520, Type 1 lock-on attack gauge value 522, type 2 lock-on attack count 524, movement prohibition flag 526, lock-on release timer 528, lock-on target character ID 530, target character ID 532, and touch operation trajectory data 534 And remember. In addition, data (for example, position coordinates and attitude information in the three-dimensional virtual space coordinate system of the virtual camera) necessary for executing the process related to the progress of the game are stored as appropriate.

  The trajectory shape dictionary data 504 is dictionary data in which data serving as a reference for the trajectory type determination unit 214 to determine the type of trajectory shape is defined for each trajectory type.

  The game space initial setting data 510 stores various data for forming the game space in the three-dimensional virtual space. For example, model data, texture data, and motion data related to an arrangement object such as a ground surface, a building, a tree, a river, and a rock on which the player character 2 and the enemy character 4 move are included.

  The character initial setting data 512 stores various initial setting data of the player character 2 and the enemy character 4. For example, for the player character 2, model data, texture data, motion data, an initial value of a proof value, an attack power, a moving speed, an initial arrangement position coordinate, and the like are stored. For the enemy character 4, model data, texture data, motion data, initial strength values, attack power, movement speed, attack pattern, movement pattern, appearance position coordinates, and the like are stored. In addition, data on a special display form for displaying the lock-on marker 10 and the target marker 16 given to the enemy character 4 is also included here.

  The character status data 514 stores data indicating the latest state of each character. For example, as shown in FIG. 10, in correspondence with a character ID 514a, a three-dimensional virtual space position coordinate 514b, a moving speed vector 514c, a game screen coordinate system position coordinate 514d, an attack direction vector 514e, a motion data ID 514f, a motion data frame number Data such as 514 g and current proof stress value 514 h are stored. Of course, in addition to this, data associated with each character as the game progresses can be stored as appropriate.

The three-dimensional virtual space position coordinate 514b stores the current position coordinates of the representative point in the three-dimensional virtual space coordinate system of the corresponding character.
The moving speed vector 514c stores the current moving speed vector of the corresponding character in the three-dimensional virtual space coordinate system.
The game screen coordinate system position coordinate 514d stores the position coordinate of the representative point indicating where the corresponding character is displayed in the game screen coordinate system.
The attack direction vector 514e stores a shooting direction, that is, a direction vector representing the direction of the hand holding the gun for the player character 2, and stores a direction vector for emitting the ball 6 for the enemy character 4.
The motion data ID 514f stores the identification information of the motion data used for the current motion control of the corresponding character, and stores the frame number currently reproduced in the motion data in the motion data frame number 514g.
The current proof strength value 514h stores the current proof strength value that has been subtracted by receiving an attack from the opponent with whom the corresponding character engages.

  The standard attack flag 516, the first type lock-on attack flag 518, and the second type lock-on attack flag 520 indicate the type of attack action of the player character 2 to be executed or being executed. The game calculation unit 210 sets “1” to the attack flag associated with the type of the trajectory shape of the touch operation determined by the trajectory type determination unit 214 and sets the flag. Then, when performing the motion control of the player character 2, the motion control is performed with reference to these attack flags so that the attack motion with the flag set is performed. In the initial state such as at the start of the game, the standard attack flag 516 is set to “1”.

  The first-type lock-on attack gauge value 522 is a parameter value that is automatically added when the first-type lock-on attack is not performed by the game calculation unit 210 and is subtracted when the first-type lock-on attack is performed. It is a barometer that is a measure of how much the first type lock-on attack can be executed. Specifically, the maximum value is 60 points, and when the first type lock-on attack is not executed, it is automatically added to 0.2 points / frame or 1 point / second. 4 points will be deducted when firing once.

  The number of second type lock-on attacks 524 is a parameter value that is reset to “0” by the game operation unit 210 when the second type lock-on attack is activated, and is incremented by “1” for each shot. Indicates how many times you have fired in a two-type lock-on attack. When the number of second type lock-on attacks 524 reaches an upper limit (for example, “12”), the second type lock-on attacks are terminated.

The movement prohibition flag 526 is set to “1” by the game calculation unit 210 when the second type lock-on attack is activated. Then, at the end of the second type lock-on attack or when the trajectory type determination unit 214 determines that the trajectory type is circular or dotted (that is, an operation input related to the first type lock-on attack and the standard attack has been made) To 0).
If the flag is “1” and the flag is set, the game calculation unit 210 restricts the movement of the player character 2 even if a movement operation input is made from the direction input unit 102.

  The lock-on release timer 528 is a timer that is activated when it is determined by the game computing unit 210 that an operation input related to the first type lock-on attack has been made, and is timed up by a predetermined time (for example, 7 seconds). When the timer expires, the game calculation unit 210 cancels the registration of the lock-on target.

  The lock-on target character ID 530 stores identification information of the enemy character 4 extracted as a lock-on target. At the time of deregistration, the stored information is cleared. The target character ID 532 stores identification information of any enemy character registered as a lock-on target.

  In the touch operation locus data 534, the position coordinates in the game screen coordinate system of the contact position obtained based on the position information detected by the contact position detection unit 104 by the contact operation input position acquisition unit 212 are stored in time series in the detection order. The Alternatively, the approximate curve function of the trajectory obtained from them may be stored. Then, the touch operation trajectory data 534 is cleared at an appropriate timing after the game operation unit 210 determines the attack type based on the trajectory shape type determination or after the execution of the attack operation, and the next touch operation is performed. Preparations for storing the contact position information relating to the are made.

[Description of operation]
Next, the operation of the portable game device 1400 in this embodiment will be described.
FIG. 11 is a flowchart for explaining the main processing flow in the present embodiment. The processing described here is realized by the processing unit 200 reading and executing the system program 501 and the game program 502. Note that although description of the output of the game sound is omitted here, the sound generation unit 250 generates a sound signal of the game sound and causes the sound output unit 350 to emit the sound as the game progresses, as in a known game. Shall.

  As shown in the figure, the game operation unit 210 first refers to the game space initial setting data 510 and the character initial setting data 512 to form a game space in the three-dimensional virtual space (step S2). In the game space, a player character 2, an enemy character 4, and a virtual camera for photographing the player character 2 and its surroundings are arranged (step S4).

  Next, the processing unit 200 initializes flags and the like (step S6). Specifically, the standard attack flag 516 is set to “1”, and the first type lock-on attack flag 518, the second type lock-on attack flag 520, and the movement prohibition flag 526 are set to “0”. The first type lock-on attack gauge value 522 is set to a predetermined initial value, and the second type lock-on attack number 524 is set to “0”. Further, the lock-on target character ID 530 and the target character ID 532 are not registered, and the touch operation locus data 534 is also cleared.

  If the initialization process is performed, the processing unit 200 starts the automatic control of the virtual camera, and also starts the process of rendering the image captured by the virtual camera to generate a game image and displaying it on the image display unit 360. (Step S8). Thereafter, a game image is generated in a predetermined cycle and displayed on the second liquid crystal display 1408.

  Further, automatic control of the movement operation and attack operation of the enemy character 4 is started (step S10). The action control of the enemy character 4 is realized in the same manner as the control of a known NPC (non-player character). As the enemy character 4 moves, the parameter values of the character status data 514 associated with the enemy character 4 are appropriately changed.

  If the game is started (YES in step S12), the processing unit 200 collates with the trajectory shape dictionary data 504, thereby determining the trajectory by the touch operation from the time series change of the contact position detected by the contact position detecting unit 104. The shape type is determined (step S14). In this embodiment, three types of circles, crosses, and dots (that is, equivalent to simple touch and tap operations) are determined. The trajectory shape type determination technique can be realized by appropriately using a recognition technique such as character input using a touch panel. The trajectory information in the game screen coordinate system is temporarily stored in the storage unit 500 as trajectory point sequence data or an approximate curve function. Of course, other types such as “line” can be included in the track type according to the contents of the game.

  When the type of trajectory shape is determined, an attack type determination process is executed to determine the type of attack action of the player character based on the determined type of trajectory shape, and to execute the attack. Various settings are made (step S16).

  FIG. 12 is a flowchart for explaining the flow of the attack type determination process in the present embodiment. When the determined locus shape type is “circular” (YES in step S30), the processing unit 200 refers to the character status data 514, and the current game screen coordinate system position coordinate 514d is a locus by the current touch operation. The presence / absence of the enemy character 4 falling within the range is determined (step S32). If there is an enemy character 4 displayed in the trajectory (YES in step S32), the processing unit 200 stores and registers the character ID 514a of the corresponding enemy character 4 in the lock-on target character ID 530 (step S32). S34).

  Next, the processing unit 200 assigns and displays the lock-on marker 10 to the registered enemy character (step S36). In this embodiment, since the circular trajectory is an operation input related to the first type lock-on attack, the first type lock-on attack flag 518 is set to “1”, and the standard attack flag 516 and the second type The lock-on attack flag 520 and the movement prohibition flag 526 are set to “0” (step S38). Then, the lock-on release timer 528 is activated (step S40), and the attack type determination process is terminated.

  When the trajectory shape type determination result is a cross (YES in step S50), the processing unit 200 determines whether or not there is an enemy character displayed at the intersection of the cross on the game screen (step S52). Specifically, the determination may be made by referring to the game screen coordinate system position coordinates 514d of the character status data 514 regarding the enemy character based on whether or not the boundary box is at the intersection position of the cross locus.

  If there is an enemy character displayed at the intersection of the crosses (YES in step S52), the processing unit 200 stores the character ID 514a of the enemy character in the lock-on target character ID 530 and performs registration processing (step S54). ), The lock-on marker 10 is given and displayed (step S56).

  Next, in the present embodiment, since the cross locus is an operation input related to the second type lock-on attack, the processing unit 200 sets the second type lock-on attack flag 520 and the movement prohibition flag 526 to “1”. While the flag is set, “0” is stored in the other standard attack flag 516 and the first type lock-on attack flag 518, and the flag is returned (step S58).

  In addition, when the determination result of the trajectory type is point-like, that is, when one touch is made to indicate only one point (it is determined that the tap operation has been performed) (YES in step S70), the processing unit 200 determines the character related to the player character 2. The first type lock-on attack operation input determination area 12 in which the latest touch position is obtained with reference to the game screen coordinate system position coordinate 514d with reference to the game screen coordinate system position coordinate 514d and the touch operation locus data 534 of the status data 514. In the first type lock-on attack operation input determination area 12 is determined (step S72).

  If it is determined that the outside of the first type lock-on attack operation input determination area 12 is touched (YES in step S72), the processing unit 200 determines that an attack operation input of a standard attack has been made, and the standard attack While the flag 516 is set to “1”, the first type lock-on attack flag 518, the second type lock-on attack flag 520, and the movement prohibition flag 526 are set to “0” (step S80). Further, the lock-on release timer 528 is reset (step S82), the lock-on target character ID 530 and the target character ID 532 are cleared (step S84), and the attack type determination process ends.

  On the other hand, when the determination result of the trajectory type is neither a circle, a cross, nor a dot (NO in step S70), the processing unit 200 determines whether the lock-on release timer 528 has timed out and has timed out the specified time. (Step S74).

  If the timer has reached the specified time (YES in step S74), the processing unit 200 sets the standard attack flag 516 to “1”, the first type lock-on attack flag 518, and the second type lock-on attack. The flag 520 and the movement prohibition flag 526 are set to “0” (step S80). Further, the lock-on release timer 528 is reset (step S82), the lock-on target character ID 530 and the target character ID 532 are cleared (step S84), and the attack type determination process ends.

  When the attack type determination process is completed, returning to the flowchart of FIG. 11, the processing unit 200 next executes the attack action process to cause the player character 2 to perform the type of attack action determined in the attack type determination process. (Step S80).

  FIG. 13 is a flowchart for explaining the flow of the attack operation process in the present embodiment. In the attack operation process, when the first type lock-on attack flag 518 is “1” (YES in step S100), the processing unit 200 determines whether or not the first type lock-on attack operation input determination area 12 is touched. Determination is made (step S102). Specifically, the touch position coordinates of the latest game screen coordinate system stored in the touch operation trajectory data 534 is the first of a predetermined size that is obtained using the game screen coordinate system position coordinates 514d of the player character 2 as a reference point. It is determined whether or not it falls within the seed lock-on attack operation input determination area 12.

  When the first type lock-on attack operation input determination area 12 is touched (YES in step S102), the processing unit 200 further confirms that the first type lock-on attack gauge value 522 is not “0”. (Step S104).

If the first type lock-on attack gauge value 522 is not “0” (YES in step S104), the first type lock-on attack is activated.
The processing unit 200 refers to the lock-on target character ID 530 and determines whether there are a plurality of lock-on targets (step S106). If there are a plurality of lock-on targets (YES in step S106), the processing unit 200 selects any one of the enemy characters that are the lock-on targets as an attack target (target), and the identification information is selected. It is stored in the target character ID 532 and registered as a target (step S108). Then, in order to clearly indicate to the player that the target has been selected, a target marker 16 is given to the selected enemy character 4 (step S110). On the other hand, if the lock-on target is single, the enemy character is registered as a target as it is, and the target marker 16 is not displayed (step S112).

  Next, the processing unit 200 controls the movement so that the player character 2 fires the target enemy character once (step S114), clears the touch operation trajectory data 534, and prepares for the next touch operation (step S116).

Then, the resistance strength subtraction process of the enemy character that has been attacked is executed, and the current strength value 514h of the character status data 514 of the enemy character is updated (step S118).
As a result of the proof strength subtraction process, when the current proof strength value 514h of the attacked enemy character is “0” or less (YES in step S120), the processing unit 200 determines that the enemy character has been destroyed and disappears. Processing is executed (step S122). By this annihilation process, the enemy character is not displayed in the game space as in the known game, and is excluded from the subsequent automatic operation control process for the enemy character. In addition, the identification information of the enemy character is cleared from the lock-on target character ID 530 and the registration as the lock-on target is released.

  Next, the processing unit 200 subtracts the first type lock-on attack gauge value 522 by a predetermined point (for example, 4 points) (step S124), and displays the first type lock-on attack gauge 14 in the game screen according to the subtraction result. Is updated (step S126). The minimum value of the first type lock-on attack gauge value 522 is “0”.

  If the first-type lock-on attack gauge value 522 does not reach “0” as a result of the subtraction process, the attack action process is terminated as it is, but if the gauge value has reached “0” (step In S128, the processing unit 200 sets the first type lock-on attack flag 518 to “0”, the standard attack flag 516 to “1”, and further clears the lock-on target character ID 530 and the target character ID 532 ( Step S130), the attack operation process is terminated.

  On the other hand, when the first type lock-on attack flag is not “1” (NO in step S100), or when the attack flag is “1” but the first type lock-on attack input determination area 12 is not touched (NO in step S102), or even if the first type lock-on attack input determination area 12 is touched, it is determined that the first type lock-on attack gauge value 522 is insufficient and the conditions for a special attack are not in place (NO in step S104), the process proceeds to the flowchart in FIG.

  In FIG. 14, when the second type lock-on attack flag 520 is “1” (YES in step S <b> 140), the processing unit 200 refers to the lock-on target character ID 530 and sets the lock-on target enemy character as 2 as a target. Operation control is performed so as to continuously shoot with a claw gun (step S142).

  Next, the strength value subtraction process of the attacked enemy character is performed (step S144). If the current strength value 514h of the enemy character has reached “0” (YES in step S146), the processing unit In step S148, the enemy character disappearing process 200 is executed.

  Next, the processing unit 200 adds “1” to the number of second type lock-on attacks 524 (step S150). As a result, when the number of attacks reaches the prescribed upper limit (YES in step S152), the processing unit 200 returns the second type lock-on attack flag to “0”, while setting the standard attack flag 516 to “ 1 ”(step S154), the lock-on target character ID 530 and the target character ID 532 are cleared to cancel the registration (step S156), and the attack action process is terminated.

  On the other hand, when the standard attack flag 516 is “1” (YES in step S170), the processing unit 200 refers to the touch operation trajectory data 534 and moves the player character 2 to fire one shot in the direction of the latest touch position. Is controlled (step S172).

Next, the enemy character's impact determination processing is performed (step S174). If there is an impacted enemy character (YES in step S176), the resistance value of the impacted enemy character is subtracted and the current strength value 514h is updated. (Step S178).
If the current proof value 514h of the enemy character has reached “0” (YES in step S180), the processing unit 200 executes the disappearance process of the enemy character (step S182).

  Next, since the processing unit 200 has performed the operation process corresponding to the current touch operation, the touch operation trajectory data 534 is cleared and prepared for the next touch operation (step S184), and the attack operation is terminated. To do.

  When the attack operation process is completed, the process returns to the flowchart of FIG. 11, and the processing unit 200 determines whether or not a movement operation input has been made to the direction input unit 102, that is, the direction input key 1402 (step S200).

When the movement operation input is made (YES in step S200), the processing unit 200 refers to the movement prohibition flag 526. If the flag is not “1” (NO in step S202), the movement of the player character 2 is controlled in accordance with the movement operation input to the direction input unit 102, and the three-dimensional virtual space position coordinates 514b of the character status data 514 are controlled. The moving speed vector 514c, the game screen coordinate system position coordinates 514d, etc. are updated (step S204).
On the other hand, when the movement prohibition flag 526 is “1” (YES in step S202), the processing unit 200 determines that the second type lock-on attack is activated, and the movement operation input is input to the direction input unit 102. Limit this even if it is done. In the present embodiment, the movement operation input is determined to be invalid and movement control is not performed.

  Next, the processing unit 200 executes a bullet determination process for the player character 2 (step S206), and performs a strength update process according to the result of the bullet determination (step S208). If the player character 2 is not hit, the current strength value 514h of the player character 2 is not changed by the strength update process.

  Next, the processing unit 200 refers to the first type lock-on attack flag 518. If the attack flag is not “1” (YES in step S210), the first type lock-on attack gauge value 522 is set to a predetermined point (for example, , 0.2 point / frame, 1 point / second, etc.) is added to recover the gauge value (step S212).

  Next, the processing unit 200 determines whether or not the current game progress condition satisfies a predetermined game end condition (step S214). In the present embodiment, it is determined that the game end condition is satisfied when all the enemy characters 4 are defeated and when the player character 2 is attacked by the enemy character 4 and the strength value becomes “0”.

  If the game end condition is not satisfied (NO in step S214), the process proceeds to step S14. If the game end condition is satisfied (YES in step S214), a predetermined game end process is executed (step S216). ), A series of processing ends.

  As described above, according to the present embodiment, it is possible to perform an attack operation input on the touch panel 1409 in parallel with the stylus pen 1416 while performing a movement operation input on the direction input key 1402. It is possible to coordinate the movement and attack such as “attacking the enemy while attacking”.

  Also, by drawing different types of trajectories by sliding operation when touching the touch panel 1409, it is possible to input the attack type selection by so-called "lock-on attack" and the attack target selection at a time, Both movement operation input and attack operation input can be realized at a higher operability level.

  Moreover, the input of the attack timing is realized by touch operation (tap operation) of the player character 2 (strictly speaking, the first type lock-on attack operation input determination area 12 set around the representative point of the player character 2). Therefore, since the viewpoint can be concentrated only on the player character, there is also an advantage that it is easier to avoid an enemy attack.

  In this embodiment, the type of locus shape assigned to the second type lock-on attack is “cross”, but other closed region shapes that can form a boundary surrounding the specific region may be used. For example, as in the locus 8B of FIG. 15, the type of locus shape corresponding to the second type lock-on attack is set to “triangle”, and within the range surrounded by the locus 8B, as in the process related to the first type lock-on attack. The displayed enemy character 4a may be extracted and registered as an attack target.

  Further, in the present embodiment, the movement of the player character 2 is restricted during the second type lock-on attack.

[Second Embodiment]
Next, a second embodiment to which the present invention is applied will be described. This embodiment is basically the same as the first embodiment, but has a configuration in which an attack attribute can be easily specified when an attack operation related to the first type lock-on attack is input. Here, only differences from the first embodiment will be described, and the same components as those in the first embodiment are denoted by the same reference numerals.

FIG. 16 is a conceptual diagram for explaining the attack operation input of the first type lock-on attack and the attack action of the player character 2 corresponding to the attack operation input in the present embodiment.
In this embodiment, when a trajectory surrounding the enemy character 4 is drawn on the touch panel 1409, a first type lock-on attack is activated, and an attack attribute icon 20 indicating an attack attribute is displayed in the vicinity of the player character 2. The attack attribute referred to here corresponds to a magic attack attribute referred to in RPG (role playing game), and for example, “fire”, “lightning”, “poison” can be set. Then, the attack attribute icons 20 are displayed with attribute patterns corresponding to the number of attack attributes that the player character 2 can use. In the example of the figure, the right corresponds to the attribute of “lightning” and the left corresponds to the attribute of “fire”.

  When any one of the attack attribute icons 20 is tapped with the stylus pen 1416 or the like, the player character 2 fires one shot each time in the same manner as the tap to the first type lock-on attack operation input determination area 12 in the first embodiment. . At this time, an attribute corresponding to the touched attack attribute icon 20 is given to the attack, and an attack power higher than usual is exhibited by compatibility with the attribute of the enemy character 4 as in the case of a known RPG.

FIG. 17 is a functional block diagram illustrating a functional configuration example according to the present embodiment. In the present embodiment, icon setting data 536 is stored in the storage unit 500.
In the icon setting data 536, image data for displaying the attack attribute icon 20 is stored in association with the attack attribute.
In the character initial setting data 512, the compatibility with the attack attribute is appropriately set for each type of enemy character. Specifically, for each attack attribute of the attack by the player character 2, a value subtracted from the strength value when an attack with the magic attribute is received is associated.

  FIG. 18 is a flowchart for explaining the flow of the attack operation process in the present embodiment. Although it is basically the same as the flow of the attack operation process of the first embodiment, when the first type lock-on attack flag 518 is “1” (YES in step S100), the processing unit 200 immediately sets the icon setting data 536. , The attack attribute icon 20 is displayed at a predetermined relative position in the vicinity of the player character 2 (step S101). Then, instead of step S102 of the first embodiment, it is determined whether or not the latest touched position is on any of the attack attribute icons 20 displayed in step S101 (step S103).

When the attack attribute icon 20 is touched, the process related to the confirmation of the activation condition of the first type lock-on attack is further executed as in the first embodiment (step S104), and the target selection process is performed (step S104). S106 to S112).
Then, instead of step S114 of the first embodiment, the player character 2 performs an attack on the enemy character selected as the target with the attack attribute associated with the touch-operated attack attribute icon 20. The operation is controlled (step S115).

For the attack attribute icon 20, when the first lock-on attack gauge value 522 reaches "0" (YES in step S128), various flag operations related to the release of the first-type lock-on attack (step S130). ), The displayed attack attribute icon 20 is hidden (step S132).
Further, when the first type lock-on attack flag 518 is not “1” (NO in step S100), or when the condition for activating the first type lock-on attack is not satisfied (NO in step S103, NO in step S104). ) Is also executed to hide the attack attribute icon 20 (step S134).

  Therefore, according to the present embodiment, the same effects as in the first embodiment can be obtained, and an attack attribute can also be input by the timing input operation of the attack operation input, so that higher operability can be realized. Further, since the attack attribute icon 20 is displayed in the vicinity of the player character 2, the viewpoint is kept facing the player character 2 as in the touch operation to the first type lock-on attack operation input determination area 12 of the first embodiment. The effect of being able to concentrate on the moving operation is obtained.
