Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game for moving an object (object) such as a motorcycle on a display in response to an operation of a user (player), such as a driving (auto racing) game. The present invention relates to a game device equipped with a game program.

[0002]

2. Description of the Related Art With the development of computer technology, game devices have become sharper, whether for home or business use.
There is a demand for more realistic images. Generally, a game device provides a computer device with a built-in computer device for executing a game program stored in advance, and an operation signal for moving an object to be expressed by the game and for giving other commands to the computer device. An operating device, a display for displaying an image associated with game development when a game program is executed by a computer device, and an audio device for generating sound associated with the game development are provided.

[0003] As one of this type of game device, a device having a car-shaped casing or a motorbike-shaped casing is known ("Sega Rally Championship, Manxtey" manufactured by SEGA ENTERPRISE CO., LTD.). tea"). In these game devices, a mechanism has been proposed in which a character displayed on a screen, for example, a vehicle or a player (player) in a drive game (auto racing game) can be selected according to a user's preference. This is widely done in games in other fields.

In this type of game device, of the characters displayed on the screen, a character located in the near side in the virtual space of the game device is given a high priority, and is given priority over a low priority character. On the screen.

Further, among conventional game devices, there is known an aerial battle simulation game device provided with a lock-on mechanism for aiming at an enemy aircraft operated by a user with respect to its own aircraft.

[0006]

By developing the above conventional example, when changing from the current character being operated by the user to another character, instead of changing from one character to another character at once, It is also conceivable to set the process of the change in stages. At this time, if it is necessary to prepare a large amount of all the characters in the process as image data of an intermediate shape, there is a disadvantage that the memory capacity increases, and it is necessary to prepare a large number of image data. There was a disadvantage.

[0007] Further, when displaying a character when the priority of a character formed by a two-dimensional scroll surface is high, displaying the scroll surface causes the scroll surface to be displayed on another character. However, there was a problem that it was hidden on the scroll surface. At this time, if the characters are of polygon data, it is possible to average the color data of the two overlapping characters for each pixel of the display screen and display both characters simultaneously on the screen. In this case, the calculation load applied to the control means of the game device increases.

Further, in a game device having a lock-on mechanism, skill is required to successfully lock on an opponent character such as an enemy machine or an enemy vehicle. However, there is a disadvantage that lock-on cannot be easily performed due to poor stability.

In order to solve such a problem, the present invention reduces the image data and reproduces a scene in which one shape of an object such as a character continuously changes to another shape. It is an object of the present invention to provide a method and a game device that can be used.

Still another object of the present invention is to provide a novel mechanism capable of overlapping and quasi-transparently illuminating an object together and displaying them on a screen.

Still another object of the present invention is to provide a game device which can efficiently and surely aim a target object on the other side.

Image deformation processing means for calculating an intermediate shape using a variable indicating the degree of mixture of image data of two objects, and displaying the intermediate shape obtained by the image deformation processing means on a screen. Features.

[0013] The object is, for example, a motorcycle on a game program. The image data of the target includes a position vector and link information of the position vector.

The link information processing means is switched when a variable indicating the degree of coexistence of image data of two objects is a predetermined value. The image transformation processing means converts the image data of the object having a predetermined shape into P
n, Qn represents image data of an object having another shape, and t represents a variable indicating the degree of coexistence of image data of two objects,
When the image data of the intermediate shape is Rn, the image data Pn is calculated using Rn = (1−t) Pn + tQn, and when the image data of the two objects does not match, the image data Pn of the object having a predetermined shape is obtained. The image data of the object having another shape is obtained from Pg = G from the center of gravity G of.

Further, in order to achieve the second object, the game device of the present invention displays a predetermined object,
A game device for displaying a scroll plane, wherein the scroll plane performs a process of repeatedly displaying and hiding the scroll plane at predetermined time intervals. A translucent scroll screen is displayed on the screen.

The translucent display processing means switches two kinds of window bit masks for one kind of scroll plane data at predetermined time intervals, and displays one line at a time.
A non-display process is performed.

The translucent display processing means switches the data of two types of scroll planes for one type of window bit mask at predetermined time intervals and displays the data for each line.
A non-display process is performed.

The translucent display processing means performs display and non-display processing by switching two types of complementary scroll planes one by one at predetermined time intervals. The certain time is 1/60 second.

A game device which achieves the third object is:
A game device for displaying a predetermined target object, displaying an enemy (enemy target object), and locking on (pointing) an enemy located in front of the target object, wherein the target object and a lock-on sight (pointing cursor) Lock-on processing means for determining that the enemy is locked on when an enemy enters a predetermined area connecting the enemy and a screen locked on by the lock-on processing means is displayed on the screen. .

In the twelfth aspect of the invention, the lock-on processing means displays the object in front of the direction in which the object is facing, and a distance between a line segment connecting the object and the lock-on site and the enemy is equal to or less than a certain value. And processing is performed when the lock-on is made.

The lock-on processing means displays the object in front of the direction in which the object is facing and locks on all enemy whose distance between the line segment connecting the object and the lock-on site and the enemy is less than a certain value. It is characterized by that.

The polygon data refers to a data group of relative or absolute coordinates of each vertex of a polygon (polygon: mainly a triangle or a quadrangle) formed of a set of a plurality of vertices. The terrain data ROM 109 stores relatively coarsely set polygon data that is sufficient for executing a collision determination between the motorcycle and the terrain. On the other hand, the shape data R

The scroll data arithmetic unit 107 is a character,
Alternatively, data of a scroll screen such as a part of the background is calculated. The calculating device 107 and the frame buffer 115 are composed of an image synthesizing device 116 and a D / A converter 1.
17 to the display 6. Thereby, a polygon screen (simulation result) of a motorcycle, terrain (background), etc. temporarily stored in the frame buffer 115
And a scroll screen of character information such as a speed value and a lap time are synthesized according to the designated priority, and final frame image data is generated. This image data is converted into an analog signal by the D / A converter 117 and sent to the display 6, where the image of the driving game is displayed in real time.

[Outline of Game] The basic operation of the above-described game apparatus 1 will be described with reference to FIGS.
Next, a new image processing technique being processed in the game apparatus 1 will be described with reference to FIGS.

(Summary of Motorcycle Image Transformation Processing and Scroll Screen Translucent Display Processing) FIGS. 4 to 6 are diagrams for explaining image processing of a motorcycle game executed by the CPU 101. FIG. Here, FIG.
FIG. 5 is a flowchart, and FIGS. 5 and 6 are diagrams for explaining screens resulting from the processing in the flowchart of FIG. Note that the image processing of the motorcycle includes image deformation processing, translucent display processing of a scroll screen, and lock-on processing for an enemy. The contents shown in FIGS. It relates to an outline of the translucent display processing.

When the game apparatus 1 starts, the CPU 101
Starts the process of the flowchart in FIG. 4, and displays a character player selection screen 50 operated by the user shown in FIG. 5 (step (S) 201). In this step 201, the CPU 101 executes the translucent display processing of the scroll screen to display the face of the player 51 inside the player selection screen 50, the motorcycle 52 and the selection information 53 necessary for screen selection.
Is displayed. As shown in FIG. 5, the selection information 53 displayed on the player selection screen 50 is “PLAYER SELECT”, and the shape of the player 51 is “entry (ENTRY) 02”.
For motorcycle 52, "VIPER 0"
And "Select with left and right and decide with start button" are displayed in characters.

Next, the CPU 101 determines whether or not the start button (viewpoint switching button 22) has been pressed (S202). When it is determined that the button is not pressed (S202; NO), the CPU 101 continues to display the player selection screen 50 shown in FIG. 5 (S201-S).
202; NO).

Here, the user selects the player selection screen 5
0, while watching player 51, “Entry (EN
TRY) 03 ”and select the start button (viewpoint switch button 2
When 2) is pressed (S202; YES), the CPU 101
Shifts to step 203 to execute the above-mentioned translucent display processing of the scroll screen on the screen 50 of FIG. 5 and execute the transformation processing.

That is, the CPU 101 gradually changes the screen 50 shown in FIG. 5 (the screen 50a in FIG. 6A) to the screen 50b in FIG. 6B. Next, the CPU 101
Are displayed on the screen 50b of FIG. 6 (b) to the screen 50 of FIG.
Deform gradually to c. Thereby, the screen 50 of FIG.
(Screen 50a in FIG. 6A) is the screen 50b in FIG. 6B.
And the motorcycle 52 becomes only parts (polygons). Next, the screen 50b shown in FIG.
The screen (c) is gradually transformed into a part (polygon) of the motorcycle 52 and the entry (EN
TRY) 03 ".

Here, if the player is dissatisfied with, for example, the shape of the motorcycle or the face of the player, he or she performs an operation for further changing the shape, and the CPU 101 detects this (S204; NO). Then, the process returns to the initial screen process (S201).

On the other hand, if the user is satisfied with the predetermined shape, the CPU 101 detects this by pressing the start button (viewpoint switch button 22) (S204; YE).
S), the process exits from this process and shifts to the game process.

Therefore, in the above-described processing, two processings of the image deformation processing and the translucent display processing of the scroll screen are performed with respect to the novel image processing technique of the present invention.

(Outline of Game Process Including Lock-On Process for Enemy) FIGS. 7 to 10 are diagrams for explaining the outline of the game process including the lock-on process for the enemy and the translucent display process of the scroll screen. , FIG. 7 is a flowchart of a game process and the like, and FIGS. 8, 9 and 10 are views showing screens obtained as a result of the processing in the flowchart.

The CPU 101 starts the processing shown in the flowchart of FIG. First, operation information relating to driving of a motorcycle by the user operating the motorcycle-type operating device 2, for example, the motorcycle class 13 of the motorcycle-type operating device 2
Is read as a digital quantity via the input / output interface 106 (step 301). The kick button is an input means for realizing a screen in which a user, that is, a player riding a motorcycle on a game screen operated by a player kicks up a rider on a suitable vehicle.

Next, the CPU 101 determines in step 302
Then, a calculation process of a simulation (simulated driving) of the movement of the motorcycle 52 is executed based on the operation information (S301). Further, the CPU 101 determines whether the kick button 21 is continuously pressed (S30).
3).

When the CPU 101 determines that the kick button 21 has not been pressed (S303; NO),
Command creation of a screen without lock-on site (S30)
4). Then, the CPU 101 executes the translucent display processing of the scroll screen for a predetermined display area of the created screen, executes the display processing of those screens (S305), and exits the processing.

As a result, a game screen 60 as shown in FIG. This game screen 60 shows the motorcycle 5 on which the player 51 is riding.
2, enemy (enemy car) 61, tap time 6 for one round
2, the remaining seconds 63, the current ranking 64, the radar 65 indicating the positional relationship between the own vehicle and the enemy vehicle, and the speedometer 66. Radar 65 in this game screen 60
And the speedometer 66 is subjected to translucent display processing of a scroll screen.

On the other hand, the CPU 101
Is determined to be continuously pressed (S30
3; YES), a command to create a screen with a lock-on site, a lock-on process, and an attack process are executed (S30).
6). Then, the CPU 101 executes the translucent display processing of the scroll screen for a predetermined display area of the created screen, executes the display processing of those screens (S305), and exits the processing.

As a result, a game screen 60a as shown in FIG. 9 is displayed on the display 6. The game screen 60a includes a motorcycle 52 on which the player 51 is riding, a one-lap tap time 62, the number of seconds remaining 63, a current ranking 64, a radar 65, a speedometer 66, and a lock-on site 67. In the game screen 60, the radar 65 and the speedometer 66 are subjected to translucent display processing of a scroll screen. Lock-on means aiming at a suitable vehicle, and this aiming is called lock-on site.

When the CPU 101 is executing a command to create a screen with a lock-on site, a lock-on process, and an attack process (S306), the enemy 61 appears, and the enemy 61 moves to a distance at which the enemy 61 can lock on. At some point, the enemy 61 will be locked on. Screen 60b displayed on display 6 by this processing
Has a configuration in which the lock-on site 67 overlaps the enemy 61 as shown in FIG.

[Details of Image Deformation Processing] FIG. 11
FIG. 14 to FIG. 14 are diagrams for explaining the image deformation processing. FIG. 11 is a flowchart of the image deformation processing.
Is an explanatory diagram of an initial shape and a final shape, FIG. 13 is an explanatory diagram of a case without link information, and FIG. 14 is an explanatory diagram of a state of image deformation processing.

In this image deformation processing, data of an initial shape 400 as shown in FIG. 12A and data of a final shape 440 as shown in FIG. 12B are prepared, and these data 400 and 440 are prepared. On the basis of the above, it is possible to display a state of changing from the initial shape 400 to the final shape 440.

Here, it is assumed that shape data P0 to P3 of, for example, a triangular pyramid P are stored as the initial shape 400, and shape data Q0 to Q7 of, for example, the three-dimensional Q are stored in the sound / game processing circuit 30 as the final shape 440. . When an intermediate shape is represented by R and a corner vertex is represented by a vector Rn,
The vector Rn is as follows: Rn = (1−t) Pn + tQn (1) where (O ≦ t ≦ 1).

It is assumed that Where t is two shapes 400,
440 are variables indicating the degree of coexistence, where t = 0 is the initial shape and t = 1 is the final shape. Therefore, t is set to 0
The transformation is completed by changing the value from 1 to 1. These too
It is stored in the sound / game processing circuit 30.

When the triangular pyramid P is compared with the solid Q, the vertices P4, P5, P6, and P7 do not exist in the triangular pyramid P, so that the vertices R4, R5, R6, and R7 of the intermediate shape are not defined. Then, the undefined vertices R4, R
For 5, R6 and R7, the center of gravity G of the shape is defined as follows. That is, Pk = G (Equation 2). Here, G is the center of gravity of the initial shape 400 (triangular pyramid P), k is the vector Pk of the vertex of the triangular pyramid P, and the solid Q
Is k when either one of the vectors Qk of the vertices does not exist.

The shape data P1 to P3, Q1 to
Q7 has link information in addition to vertex position information. Here, the link information refers to information connecting the vertices.

If the link information is not provided, the triangular pyramid P is changed to a solid Q, and the vertices P0 to P3 of the triangular pyramid P are changed to the vertices Q0 to Q3 of the solid Q, as shown in FIG.
A quadrilateral corresponding to Q3 and having no vertices Q4 to Q7 will result. Therefore, when the shape data is t = 0, t
= 1 <0
It is necessary to change between t <1. In the example of this embodiment, the link information is changed when t = 0.5.

Next, referring to FIG.
The operation of changing from a to a solid Q will be described.

The CPU 101 first sets the initial shape 400
The shape data P0 to P3 of the (triangular pyramid P) are read, and the shape data Q0 to Q7 of the final shape 440 (solid Q) are read.
Is read (S500).

Next, the CPU 101 calculates the intermediate shape Rn by using the stored formula 1 (S501).
At this time, since t = 0, Equation 1 indicates that Rn = P
n, and only the initial shape 400 (triangular pyramid P) is displayed (time t1 in FIG. 14).

Next, the CPU 101 determines whether the variable t has become 0.5, for example (S502). At this time, since t = 0, the CPU 101 determines that the variable t is not 0.5, for example (S502; NO), and proceeds to the next step 504.

At step 504, the CPU 101 calculates t = t + m (Equation 3) for the variable t. Here, m defines the degree of change of the variable t. Therefore, for example, when the calculation of Equation 3 is performed with m = 0.1, the next variable t is t = 0.1
Becomes

Then, the CPU 101 determines whether or not the variable t> 1 (S505). At this time, t = 0.1
Therefore, the CPU 101 determines that the variable t is not greater than 1 (S505; NO), and returns to step 500 again.

Again, the CPU 101 sets the initial shape 400
The shape data P0 to P3 of the (triangular pyramid P) are read, and the shape data Q0 to Q7 of the final shape 440 (solid Q) are read.
Is read (S500).

Next, the CPU 101 calculates the intermediate shape Rn using Expression 1 (S501). At this time,
Since t = 0.1, Equation 1 is given by Rn = 0.9Pn + 0.1Qn, and the initial shape 400 (triangular pyramid P) is deformed and displayed.

Next, the CPU 101 determines whether the variable t has become 0.5, for example (S502). At this time, since t = 0, the CPU 101 determines that the variable t is not 0.5, for example (S502; NO), and proceeds to the next step 504.

In step 504, the CPU 101 calculates the equation (3) for the variable t. As a result of this calculation, the next variable t is t = 0.2.

Then, the CPU 101 determines whether or not the variable t> 1 (S505). At this time, t = 0.2
Therefore, the CPU 101 determines that the variable t is not greater than 1 (S505; NO), and returns to step 500 again.

The CPU 101 repeats the processing of the flowchart of FIG.
The initial shape 400 of the triangular pyramid P at time t1 in FIG.
At time t2 of 4, the intermediate shape 410 is obtained.

As the CPU 101 processes the flowchart of FIG. 11, when the variable t becomes 0.5 at time t3 as shown in FIG. 14 (S502; YES), the CPU 101 The link information is switched, and the equation 2 is calculated (S50).
3). As a result, as shown at time t3 in FIG.
20 will be formed. Then, the CPU 101 executes the processing after step 504.

Again, as the CPU 101 processes the flow chart of FIG. 11, the variable t becomes t = 0.5 after time t3 as shown in FIG. 14 (S5).
02; YES), the CPU 101 has already executed the link information switching process, and thus exits this step without performing the switching process. Then, the CPU 101 executes the processing after step 504. Thereafter, by repeatedly processing the flowchart of FIG. 11, the intermediate shape 420 gradually changes to a three-dimensional shape for vertices having no link information, and the intermediate shape 420 as shown at time t4 in FIG. The shape 430 is obtained.

Then, the CPU 101 processes the flowchart shown in FIG. 11, and finally becomes the final shape 440 at time t5 in FIG.

As described above, since the sound / game processing circuit 30 performs the processing, it is not necessary to store the image data that changes gradually with respect to the image. Can be reduced.

Further, according to the above embodiment, even if the vertex data of the initial shape and the final shape are different, it can be changed, so that there is no restriction on the data of the initial shape and the final shape, and Increase.

When the shape of the object after deformation is simpler than the shape before deformation, the vertices may be omitted during the deformation of the shape of the object, in addition to complementing and increasing the vertices.

[Translucent Display Processing of Scroll Screen] FIG.
5 to 18 are diagrams for explaining the translucent display processing of the scroll screen. The reason for performing the translucent display processing of the scroll screen is that when a scroll plane is displayed on the screen of the display 6, polygons and the like are hidden by the scroll plane and cannot be seen. This is to make it possible to see on the display 6 polygons and the like that are originally hidden by being displayed. Hereinafter, three processing operations of the translucent display processing of the scroll screen will be described.

(Example 1 Using Window Bit Mask) FIGS. 15 and 16 are diagrams for explaining a first example of performing a translucent display processing of a scroll screen using a window bit mask. Here, the window bit mask is such that by applying the data of the scroll surface to the mask, only the data of the scroll surface of a portion having a predetermined logical value is extracted.

Scroll surface 6 used in this embodiment
As shown in FIG. 16, the reference numeral 50 is composed of, for example, 8 bits horizontally and 1 dot vertically. In the window bit mask 651, as shown in FIG. 16, the first line is logic "1", the second line is "0", and the third line is logic "1". Window bit mask 65
2, the first line has a logic “0” as shown in FIG.
The second line is “1”, and the third line is logic “0”.

Now, the CPU 101 has, for example, 1/60
It is assumed that the flowchart of FIG. 15 is processed by the timer interrupt processing every second. The CPU 101 makes a switching determination (S600; YES), first selects the window bit mask 651, and applies the window bit mask 651 to the scroll surface 650 (S601).
Then, the CPU 101 instructs the display 6 to display the image data obtained by the application (S603),
Exit this process.

Thus, the window bit mask 6 shown in FIG. 16B is placed on the scroll surface 650 shown in FIG.
51 will be applied. As a result, of the bits of the scroll surface 650, the window bit mask 651
Is selected, and an image 653 shown in FIG. 16C is obtained. This image 653 is displayed on the display 6.
Will be displayed.

[0099] Again, the CPU 101
It is assumed that the flowchart of FIG. 15 is processed by the timer interrupt processing every second. The CPU 101 determines the switching and selects the window bit mask 651 last time, so that a different window bit mask is selected (S600; NO).

That is, the CPU 101 selects the window bit mask 652, and applies the window bit mask 652 to the scroll surface 650 (S60).
2). Then, the CPU 101 instructs the display 6 to display the image data obtained by the application (S60).
3), exit this process.

As a result, the window bit mask 6 shown in FIG. 16B is placed on the scroll surface 650 shown in FIG.
52 will be applied. As a result, among the bits of the scroll surface 650, the window bit mask 652
Is selected, and an image 654 shown in FIG. 16C is obtained. This image 654 is displayed on the display 6.
Will be displayed.

Further, the CPU 101 again executes, for example, 60
It is assumed that the flowchart of FIG. 15 is processed by the timer interrupt processing for every 1 / second. Since the CPU 101 has determined the switching and has previously selected the window bit mask 652, a different window bit mask is selected (S600; YES).

That is, the window bit mask 651
Is selected, and the window bit mask 651 is applied to the scroll surface 650 (S601). And CP
U101 instructs the display 6 to display the image data obtained by the application (S603), and exits this processing.

Thus, the window bit mask 6 shown in FIG. 16B is placed on the scroll surface 650 shown in FIG.
51 will be applied again. As a result, of the bits of the scroll surface 650, the window bit mask 6
The logical “0” portion 51 is selected, and an image 653 shown in FIG. 16C is obtained. This image 653 is displayed on the display 6.

By performing the above-described processing of FIG. 15 every 1 / 60th, the translucent image 655 as shown in FIG. 16D is displayed on the display 6.

According to the first example of the process for displaying an image translucently using the window bit mask, the scroll surface looks as if it is displayed translucently.
Polygons and the like that would otherwise be hidden by the scroll surface can be made visible. Therefore, FIG.
Since the scroll screen is displayed translucently on the player selection screen 50, the player (character) 51, which should be invisible, can be seen.

(Example 2 Using Window Bit Mask) FIG. 17 is a diagram for explaining a second example of performing a translucent display processing of a scroll screen using a window bit mask.

Scroll surface 6 used in this embodiment
Both 50a and 650b are, as shown in FIG.
For example, it is assumed that horizontal 8 bits and vertical 1 dot. In the second example, as shown in FIG. 17A, the scroll screen 650a has a logic “0” on the first line, a “1” on the second line, and a logic “0” on the third line.
Image data. Also, the scroll screen 650b
As shown in FIG. 17A, the first line is logic "1", the second line is "0", and the third line is logic "1".
Image data.

The window bit mask 651a
Means that all the lines are logic "0" as shown in FIG.
It has become.

The second example is different from the first example in that the window bit masks 651 and 652 are not alternately switched every 1/60 second, but are changed over the scroll surfaces 650a and 650a.
By switching 50b alternately every 1/60 second, the scroll surfaces 650a and 650b can be switched from FIG.
Are obtained every 1/60 second,
These images 653 and 654 are alternately displayed on the display 6 every 1/60 second.

By performing such a switching process every 1 / 60th, an image 655 that looks translucent as shown in FIG. 17D is displayed on the display 6.

According to the second example of the process of displaying an image translucently using the window bit mask, the scroll surface looks as if it is displayed translucently.
Polygons and the like that would otherwise be hidden by the scroll surface and become invisible can be made visible. Therefore, as shown in FIG. 5, the scroll screen is displayed translucently on the player selection screen 50, so that the player 51, which should be invisible, can be seen.

(Another Example of Translucent Display Process of Scroll Surface) FIG. 18 is a diagram for explaining another example of the translucent display process of a scroll surface. As shown in FIG. 18, another example of the translucent display processing of the scroll surface is not limited to one line, and is not limited to one line, as shown in FIG. 18A. Is prepared, and the scroll surfaces 661 and 662 are switched every 1 / 60th, so that a translucent image 655 as shown in FIG. 18D is displayed on the display 6.

According to another example of the process for displaying this image translucently, a polygon that appears as if the scrolling surface is displayed translucently and is originally hidden by the scrolling surface and cannot be seen. Etc. can be made visible. Therefore, as shown in FIG. 5, the scroll screen is displayed translucently on the player selection screen 50, so that the player 51, which should be invisible, can be seen.

FIG. 23 shows a game screen displayed as a result of another translucent process. Reference numeral 230 denotes a motorbike character image formed by polygon data, and reference numeral 232 denotes a rider image formed by a scroll plane, which is two-dimensional data.
Since the rider is displayed translucently as described above, it is indicated by a dotted line in the figure. The rider's scroll image is displayed on the front side of the screen because it has a higher priority than the polygon image, but it is translucent, in other words, pseudo-translucent (what looks like translucent,
Alternatively, the image of the motorbike behind the rider is also displayed at the same time. The translucent processing here is as follows.

A rider (display body) is displayed in two predetermined images,
For example, a screen corresponding to an odd-numbered scanning line and a portion corresponding to an even-numbered scanning line of a television monitor are divided and alternately displayed (every 1/30 second), so that the screen is blurred. To complete pseudo-transparency. Further, for example, separately from the scanning lines, an image of a certain display body is temporarily divided into A / B for each stitch shape, pixel, and the like, and the display of A is continued, and the display of only B and the erasure are alternately performed. Even if it is repeated, such an image can be created. [Lock-On Process for Enemy] During the execution of the game process of FIG. 7, the lock-on process for the enemy is executed in steps 303 and 304. Details of the lock-on process for this enemy will be described with reference to FIGS. Here, FIG.
9 is a principle diagram of the lock-on process, FIG. 20 is a flowchart of the lock-on process, FIG. 21 is an explanatory diagram of the locked-on state, and FIG. It is shown.

In the image data, as shown in FIG. 19, the lock on site 67 in FIG. 21 is displayed as the lock on site S, and the player 51 is displayed as the player P.

It is assumed that the lock on site S is displayed in front of the direction in which the player P is facing. A circle having a radius d is drawn for the lock-on site S and the player P, and a circle having a center at the player P and a circle having a radius d having the center at the center of the lock-on site S are set. , And the enemy E enters the tangent of both circles parallel to the line l and connects to the lock-on site S.

That is, assuming that the distance from the enemy E to the enemy E at right angles to the line segment l is d ', if the distance d' is equal to or less than the predetermined distance d, the lock-on site S is locked on (successful aiming).
It has been assumed that.

Now, the kick button (punch button) 21
By continuing to press, the CPU 101 enters a state ready for lock-on. First, the CPU 101 takes in the position and distance of the enemy E. Then, CPU10
1 calculates the distance d ′ from the line segment 1 in FIG. 19 to the enemy E.

Next, the CPU 101 compares the distance d 'to the enemy E with the fixed distance d, and when the distance d' is smaller than the fixed distance d, the CPU 101 is caught by the lock-on site S (the lock-on target S). (S700 in FIG. 20; YES).

On the other hand, the CPU 101 compares the distance d 'to the enemy E with the fixed distance d. If the distance d' is larger than the fixed distance d, the CPU 101 determines that the lock-on site S has not been caught ( S70 of FIG.
0; NO).

When the CPU 101 determines that the two nemmies E have been caught by the lock-on site S (S700 in FIG. 20; YES), the display 6
At the top, a game screen 760 as shown in FIG. 21 is displayed.

The game screen 760 shown in FIG. 21 shows the motorcycle 52 on which the player 51 is riding, two enemies 61a and 61b, a one-lap tap time 62, and six seconds remaining.
3, current ranking 64, radar 65, speedometer 6
6, and a lock-on site 67.

The radar screen 65 and the speedometer 66 of the game screen 60 are subjected to a translucent display processing of the scroll screen. Also two enemy 6
As shown in FIG. 21, 1a and 61b are displayed in a state where they are locked on at the lock-on site S.

The CPU 101 has two enemy 61a,
If it is determined that the enemy 61a has been caught on the lock-on site S (S700 in FIG. 20; YES), a lock-on flag is set for each enemy 61a, 61b (S701).

Next, the CPU 101 determines whether or not the user has released the kick button (punch button) 21 (S702). When the CPU 101 determines that the kick button 21 has not been released (S702; NO), the process returns to step 700 to determine whether or not the lock on site S has been caught.

Here, when the kick button 21 is released, the CP
When U101 determines (S702; YES), the player 51 launches a weapon and attacks the enemy 61a, which is a suitable vehicle with the lock-on flag standing in front of the virtual space and closest to the enemy 61a (step S702; YES). S7
03).

When the kick button 21 is released when the user is not stuck on the lock-on site S,
The weapon carried by the player 51 flies. At this time, since the lock-on flag has not been set (S70)
0; NO), the weapon will come off without hitting anywhere.

When there are two or more energies 761a and 761b as shown in FIG.
As shown in (2), the CPU 101 performs image processing so that the weapon flies toward the enemy 761a located closest to the front of the player 51.

Therefore, when the enemy to be attacked is the enemy 761b, as shown in FIG. 22B, the player 51 must pass the enemy 61a before attacking.

As described above, in this example, the following effects can be expected by locking on a plurality of enemies 761a,.

(1) Since lock-on situations are limited, as many enemy 761a,... As possible can be attacked when lock-on is possible.

(2) By performing a two-step procedure of locking on a plurality of enemies 761a,... And then attacking one enemy, (i) the attacking side can select an attack target, (ii) ) It is uncertain whether the attacker will be attacked even if the player is locked on.

As a further development example of the present invention, in addition to the parameters of the special effects of the car as the moving object, the sound from the loudspeaker generated along with the game development of the screen is controlled in addition to the parameters described above. Alternatively, the kickback amount to the handle kickback mechanism as the output device may be controlled.

Further, in the above-described embodiment, the contents of the game have been described on the premise of the motorcycle game, but the object to be moved may be an automobile, a ship, an aircraft, or the like.

The storage medium storing the operation program of the game machine includes the cartridge ROM described above,
In addition to the CD-ROM, a communication medium on the Internet or a personal computer net may be used.

[0138]

As described above, according to the game apparatus of the present invention, it is not necessary to store image data that changes gradually with respect to an image, so that less data is required and the memory capacity is reduced. Can be reduced.

Even if the vertex data of the initial shape is different from the vertex data of the final shape, it can be changed.
There are no restrictions on the initial and final shape data,
Versatility increases.

Further, it is possible to make the scroll surface look as if it is displayed in a translucent manner, and to make it possible to see polygons and the like which would otherwise be hidden by the scroll surface and become invisible.

Further, since lock-on situations are limited, as many enemies as possible can be attacked in lock-on situations.

In addition, lock on a plurality of enemies,
Then, by taking a two-step procedure of attacking one enemy, the attacker has the advantage of being able to select the target of the attack, and it is uncertain whether the attacker will be attacked even if locked on. Therefore, psychological upset can be caused and the game can be diversified.
