That is, the game sound may be generated by synthesizing the read start timings of the read sound data of the first and second sounds.

  The sound processing unit 117 also performs the first sound based on the attack action (for example, attack direction) of the one character or the parameters (for example, parameters indicating the character type, physical strength, etc.) set for the character. The time from when the second sound is output until the second sound is output may be adjusted. That is, the timing data for adjusting the time from the output of the first sound to the output of the second sound based on the attacking action and the parameters is obtained, and the first and second are obtained based on the obtained timing data. The sound data may be synthesized by shifting the reproduction start timing of the sound.

  The sound processing unit 117 corresponds to an attack action (for example, a weapon used for the attack action) of one character between the output of the first sound and the output of the second sound. The third sound may be output to the sound output unit 192. That is, sound specifying data for specifying the third sound corresponding to the attack action is obtained, and based on the obtained sound specifying data, the sound data of the third sound is read from the sound data storage unit 177, and the read first data is read. The sound data of the third sound and the read order of the read sound data of the first and second sounds are in the order of the first sound, the third sound, and the second sound.

Adjust at least one of the length, volume and pitch of the third sound. That is, based on the attack action and parameters, reproduction time data for adjusting the length of the third sound, volume data for adjusting the volume of the third sound, and the pitch of the third sound The game sound may be generated by adjusting the sound data of the third sound based on the obtained reproduction time data, volume data, and pitch data.

  The virtual camera control unit 118 performs a virtual camera (viewpoint) control process for generating an image that can be seen from a given (arbitrary) viewpoint in the object space. Specifically, the operation data input by the player through the operation unit 160, information such as the position, rotation angle, or speed of the object obtained by the movement / motion processing unit 112, the position (movement path) or rotation angle of the virtual camera are displayed. Based on the virtual camera data, program (movement / motion algorithm), etc. for specifying, the position (X, Y, Z) of the virtual camera in the world coordinate system, the rotation angle (for example, each axis of X, Y, Z axis) Rotation angle when rotating clockwise as viewed from the positive direction), speed, or acceleration is controlled. In short, processing for controlling the viewpoint position, the line-of-sight direction, and the angle of view is performed. When there are a plurality of virtual cameras (viewpoints), the above control process is performed for each virtual camera.

  The drawing unit 120 performs drawing processing based on the results of various processing (game processing) performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190. When generating a so-called three-dimensional game image, first, object data (model data) including vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex is input. Then, vertex processing (shading by a vertex shader) is performed based on the vertex data included in the input object data. When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary.

  In the vertex processing, according to the vertex processing program (vertex shader program, first shader program), vertex movement processing, coordinate transformation, for example, world coordinate transformation, visual field transformation (camera coordinate transformation), clipping processing, projective transformation (perspective transformation) , Projection conversion), viewport conversion (screen coordinate conversion), light source calculation, and other geometric processing are performed, and based on the processing results, the vertex data given to the vertex group constituting the object is changed (updated, adjusted). To do. Object data after the geometry processing (position coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) is stored in the object data storage unit 176.

  Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (shading or fragment processing by a pixel shader) for drawing pixels (fragments forming a display screen) constituting an image is performed.

  In pixel processing, according to a pixel processing program (pixel shader program, second shader program), various processes such as texture reading (texture mapping), color data setting / change, translucent composition, anti-aliasing, etc. are performed, and an image is processed. The final drawing color of the constituent pixels is determined, and the drawing color of the perspective-transformed object is output (drawn) to a drawing buffer 174 (a buffer capable of storing image information in units of pixels; VRAM). That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed. Thereby, an image that can be seen from the virtual camera (given viewpoint) in the object space is generated.

  The drawing unit 120 performs texture mapping, hidden surface removal processing, and the like when drawing the object.

  Texture mapping is a process for mapping a texture (texel value) stored in the texture storage unit 178 of the storage unit 170 to an object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the texture storage unit 178 of the storage unit 170 using the texture coordinates set (given) at the vertex of the object. Then, a texture that is a two-dimensional image is mapped to an object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  As the hidden surface removal processing, hidden surface removal processing by a Z buffer method (depth comparison method, Z test) using a Z buffer 179 (depth buffer) in which a Z value (depth information) of a drawing pixel is stored may be performed. it can. That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer 179 is referred to. Then, the Z value of the referenced Z buffer 179 is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is the front side when viewed from the virtual camera (for example, a small Z value). If it is, the drawing process of the drawing pixel is performed and the Z value of the Z buffer 179 is updated to a new Z value.

  Note that the game system of the present embodiment may be a device dedicated to the single player mode that can be played by only one player, or may be a device that also has a multiplayer mode that can be played by a plurality of players. Further, when a plurality of players play, game images and game sounds to be provided to the plurality of players may be generated using one terminal, or connected via a network (transmission line, communication line) or the like. Alternatively, it may be generated by distributed processing using a plurality of terminals (game machine, mobile phone).

2. Next, the method of this embodiment will be described with reference to the drawings.

2-1. Game Overview FIG. 2 shows an example of a game image of the present embodiment.

And the image which looked at the object space containing a some character from the virtual camera is produced | generated, and it displays as game image GI.

  The player can operate the operation unit to cause the character to be operated (character A or character B shown in FIG. 3) to perform a plurality of types of attack operations using the weapon SD. For example, as a plurality of attack operations with different attack directions, “vertical slashing” in which the sword SD is swung down from top to bottom, “horizontal slashing” in which the sword SD is swung from right to left or sword SD from left to right, It is possible to perform an attacking action such as a “protrusion” projecting forward. Further, the player can operate the operation unit to cause the character to take a posture such as “standing”, “squatting”, and “jumping”. Note that the player can select a weapon SD to be given to the character from a plurality of types of weapons (for example, Western sword, Japanese sword, bamboo sword).

2-2. Identification of First and Second Part Objects As shown in FIG. 3, the character of the present embodiment (here, the example of the character A shown in FIG. 2) has a plurality of parts representing the head, arms, torso, legs, etc. It is composed of a part object PO. In this embodiment, when it is determined that the attack by the attack action of one character hits the other character, the type of attack action (attack direction) of one character and the other character (character subjected to attack) Based on the posture, the first and second part objects (two part objects) are specified among the plurality of part objects PO constituting the other character.

  FIG. 4 is an example of a table referred to when specifying a part object.

  In the present embodiment, referring to the part identification table 200 shown in FIG. 4, the first part 230 and the second part 240 of the other character corresponding to the attack direction 210 of one character and the posture 220 of the other character. Is identified.

  Here, in the first part 230, when one character performs an attack action using a weapon against the other character, a part object at a position where the weapon first comes into contact is defined. The second part 240 defines a part object in which the weapon is at a position where it can escape from the body of the other character.

  For example, when the attack direction 210 of one character's attack action is “vertical slash” and the posture 220 of the other character (in this case, the character A) is “standing”, Since the movement trajectory is as shown in FIG. 5A, among the plurality of part objects constituting the other character, the “head” part object at the position where the weapon first contacts is the first part 230. The “right foot” part object at the position where the weapon is removed is defined as the second part 240.

  Further, when the attack direction 210 is “crossing from right to left” and the posture 220 is “standing”, the movement trajectory of the weapon by the attack action is as shown in FIG. The “left torso” part object at the position where the weapon first contacts is defined as the first part 230, and the “right torso” part object at the position where the weapon is removed is defined as the second part 240. Yes.

  When the attack direction 210 is “crossing from right to left” and the posture 220 is “squatting”, the movement trajectory of the weapon by the attack action is as shown in FIG. The “left arm” part object at the position where the weapon first comes in contact is defined as the first part 230, and the “right arm” part object at the position where the weapon comes out is defined as the second part 240.

  As described above, according to the present embodiment, the first part object at the position where the weapon comes in contact with the attack direction of the one character and the posture of the other character and the second position at which the weapon comes out of the body. By pre-defining the parts object, the first and second part objects corresponding to the attack action and posture can be simplified without performing the hit check process between the weapon movement trajectory and each part object each time. Can be identified by simple processing.

2-3. Identification of First and Second Sounds FIGS. 6 and 7 are examples of tables that are referred to when identifying the first and second sounds.

  In the present embodiment, the first and second sounds corresponding to the specified first and second part objects are specified and sequentially output.

  The material specifying table 300 shown in FIG. 6 defines a material 330 corresponding to each of the plurality of parts 320 of each character 310. For example, for a part object that represents armor or helmet (with armor or helmet), “metal” is defined as the material 330, and for a part object that represents fabric, “cloth” is defined as the material, and a part object that represents bare skin Is defined as “raw skin” as a material, and “shell” is defined as a material for a part object representing a shell.

  The sound specification table 400 shown in FIG. 7 defines first and second sound data 420 and 430 for specifying the first and second sounds corresponding to each material 410 of the part object. Here, the first sound data 420 is a sound generated when the weapon contacts the first part object, and a sound corresponding to the material of the part object is defined. Defines a sound that is generated when the weapon comes out of the second part object and that corresponds to the material of the part object.

  In the present embodiment, the material specifying table 300 shown in FIG. 6 is referred to, the material 300 corresponding to the first part object 320 is specified, and then the sound specifying table 400 shown in FIG. 7 is specified. The first sound data 420 corresponding to the selected material 410 is specified. Similarly, the material specifying table 300 shown in FIG. 6 is referred to, the material 300 corresponding to the second part object 320 is specified, and then the specified material 410 is specified referring to the sound specifying table 400 shown in FIG. 2nd sound data 430 corresponding to is specified.

  For example, in the case shown in FIG. 5A, “metal” is identified as the material 300 corresponding to the “head” identified as the first part object, and the first sound corresponding to the material “metal” is identified. As data 420, the sound “S1-1” generated when the weapon comes into contact with metal is specified. Similarly, “skin” is specified as the material 300 corresponding to the “right foot” specified as the second part object, and the weapon comes out of the skin as the second sound data 430 corresponding to the material “skin”. The sound “S2-3” that is sometimes generated is specified.

  Thus, according to the present embodiment, the first sound according to the material of the part object at the position where the weapon comes into contact and the second sound according to the material of the part object at the position where the weapon comes off can be easily obtained. Can be specified and output by simple processing.

2-4. Specifying Third Sound FIG. 8 is an example of a table referred to when specifying the third sound.

  In this embodiment, when it is determined that an attack by the attack action of one character hits the other character, the sound identification table 500 shown in FIG. 8 is referred to correspond to the weapon 510 used in the attack action. The third sound data 520 to be specified is specified and output. Here, the third sound data 520 defines a sound (a hit sound of the weapon itself) generated when each weapon passes through another character.

2-5. Output of First, Second, and Third Sounds FIGS. 9A and 9B are diagrams illustrating an example of a time chart when the first, second, and third sounds are sequentially output. .

  In the present embodiment, the first, second, and third sound data (waveform data) is read from the sound data storage unit 177, and the read first, second, and third sound data are shown in FIG. As shown in FIG. 9B, the first sound, the third sound, and the second sound are sequentially reproduced from the three channels (ch1, ch2, and ch3) while shifting the reproduction timing. Performs processing to synthesize (mix) the sound reproduced from the channel and output it.

  That is, when an attack using the weapon of one character hits the other character, the sound (first sound) that is generated when the weapon comes in contact with the other character's parts, The sound (third sound) generated when passing through and the sound (second sound) generated when the weapon comes out of the other character's part are sequentially reproduced while being shifted.

  As described above, according to the present embodiment, the first and second sounds specified based on the attack direction of one character, the posture of the other character, and the material of the parts of the other character, and the type of weapon are specified. The sound at the time of attack can be expressed by the combination of the 3rd sound to be performed, and the variation of the sound at the time of attack can be increased.

  In the present embodiment, based on the attack action type (attack direction) of one character, the time T1 from when the first sound starts to be output (played back) until the second sound is output, and the third The sound length T2 (the time from the start of outputting the third sound until the volume is lowered (fade out)) is adjusted.

  That is, when the attack direction of one character is “vertical cut”, the time for the weapon to pass through the other character (the time from when the weapon comes into contact with the character until it comes off) becomes longer (FIG. 5A). Therefore, as shown in FIG. 9A, the time T1 for outputting the second sound and the length T2 of the third sound are adjusted to be longer. Also, when the attack direction of one character is “horizontal slash”, the time for the weapon to pass through the other character is shortened (see FIG. 5B), so as shown in FIG. 9B. The time T1 for outputting the second sound and the length T2 of the third sound are adjusted to be shorter than in the case of “vertical cutting”.

  Also, the time T1 for outputting the second sound and the length T2 of the third sound may be adjusted based on the parameters set for one or the other character. For example, the time T1 and the length T2 are adjusted to be longer as the stamina value set for one of the attacking characters is larger or as the stamina value set for the other character under attack is smaller. You may make it do.

  In this way, according to the attack direction of one character and the parameters set for each character, the total length of the sound generated at the time of attack (after the first sound starts to be output and the second sound is finished to be output) Time).

2-6. Adjustment of the first, second, and third sounds In this embodiment, the volume of the first, second, and third sounds is adjusted and output based on the attack action (attack power) of one character. .

  FIG. 10 is a diagram illustrating the relationship between the attack power of one character and the volume of the first, second, and third sounds. As shown in FIG. 10, in the present embodiment, the first, second, and third are increased as the attack power of one character (for example, the value of the game parameter set in association with the character or the weapon possessed by the character) increases. The volume of the sound is adjusted to be loud. Further, the amount of damage received by the other character by the attacking action of one character may be obtained, and the volume of the first, second, and third sounds may be adjusted to increase as the obtained amount of damage increases. Further, the volume of the first, second, and third sounds may be adjusted to increase as the physical strength value of one character is larger or the physical strength value of the other character is smaller.

  In this embodiment, the pitches of the first, second, and third sounds are adjusted and output based on the attack action (attack power, attack direction) of one character.

  FIG. 11A is a diagram illustrating an example of changes in the pitches of the first, second, and third sounds when the attack direction of one character is “vertical cut”. FIG. 11B is a diagram showing changes in the pitch of the first, second, and third sounds when the attack direction of one character is “horizontal cut”. In FIGS. 11A and 11B, the solid line indicates the change in the pitch of each sound when the attack power is “50”, and the broken line indicates the pitch of each sound when the attack power is “10”. Shows changes.

  As shown in FIGS. 11 (A) and 11 (B), in this embodiment, the greater the attack power of one character, the greater the change in pitch (pitch change) of the first, second, and third sounds. It is adjusted so that In addition, adjustment is made so that the pitch change is greater when the attack direction of one character is “vertical cut” than when “cutting horizontal”. Further, the adjustment may be performed such that the change in the pitch of the first, second, and third sounds increases as the physical strength value of one character increases or the physical strength value of the other character decreases.

  Thus, according to this embodiment, the volume and pitch of the basic sound (first, second, and third sounds) are adjusted according to the attack power and attack direction of one character and the parameters set for each character. By doing so, the variation of the sound at the time of attack can be increased, without increasing the storage area for sound data.

3. Processing of this Embodiment Next, an example of processing of this embodiment will be described using the flowchart of FIG.

  First, the movement / motion processing unit 112 performs a motion calculation for causing a character to perform a plurality of types of attack motions using weapons or to take a specific posture based on operation data from the operation unit 160 (step S10).

  Next, based on the character position, the type of attack action (attack direction) of one character, and the posture of the other character, the hit determination unit 114 determines one character. It is determined whether or not the other character hits the other attack (step S12).

  If it is determined in step S12 that the hit has been made, the parts identification unit 116 determines the other character based on the attack direction of one character and the posture of the other character obtained by the movement / motion processing unit 112. Among the plurality of part objects constituting the character, the first and second part objects are specified (step S14).

  Next, the sound processing unit 116 identifies the first and second sounds corresponding to the material (attribute data) of the first and second part objects (step S16), and is used for the attack action of one character. The third sound corresponding to the selected weapon is identified (step S18).

  Next, the sound processing unit 116 determines the timing of outputting the second sound (the time from the start of outputting the first sound until the output of the second sound) based on the attack direction of one character. (Step S20).

  Next, the sound processing unit 116 obtains a change in volume and pitch of the first sound based on the attack direction and attack power of one character, and adjusts and outputs the first sound according to the obtained change in volume and pitch. (Step S22).

  Next, the sound processing unit 116 obtains a change in the length, volume, and pitch of the third sound based on the attack direction and attack power of one character, and after a predetermined frame from the start of the output of the first sound. Then, the third sound is adjusted and output in accordance with the obtained sound length, volume, and pitch change (step S24).

  Next, the sound processing unit 116 obtains a change in volume and pitch of the second sound based on the attack direction and attack power of one character, and at the timing determined in the process of step S20, The second sound is adjusted and output according to the change (step S26).

4). Modifications The present invention is not limited to that described in the above embodiment, and various modifications can be made. For example, terms cited as broad or synonymous terms in the description in the specification or drawings can be replaced with broad or synonymous terms in other descriptions in the specification or drawings.

  For example, in this embodiment, the case where two part objects of the other character are specified based on the attack action of one character has been described. However, one part object of the other character is specified based on the attack action of one character. Then, the first and second sounds corresponding to one specified part object may be output.

  That is, based on the attack action using the weapon of one character and the posture of the other character, the part object at the position where the weapon first contacts, or the part at the position where the weapon comes out of the body of the other character Identify the object.

  Then, with reference to the material specifying table 600 as shown in FIG. 13A, two materials 630 corresponding to the specified part object 620 are specified. Here, two materials, “metal” and “cloth”, are defined as two materials corresponding to the “right arm” part object. For example, the part object has a metal armor on the cloth clothes. It shows that it is in a layered state.

  Then, with reference to the sound specification table 700 as shown in FIG. 13B, the two sound data 720 corresponding to the two specified materials 710 are specified as the first and second sounds. For example, when the part object of “right arm” is specified, the first and second sound data “S1”, “S” corresponding to each of the two materials “metal” and “cloth” corresponding to the part object are specified. S2 "is specified. And the 3rd sound data are specified similarly to the method demonstrated by this embodiment.

  Then, the identified first, second, and third sound data are read from the sound data storage unit 177, and the read first, second, and third sound data are shown in FIG. The third sound, the first sound, and the second sound are sequentially reproduced with the reproduction timing shifted from the three channels, and the sounds reproduced from the three channels are synthesized and output. Further, as shown in FIG. 14B, the first sound, the second sound, and the third sound may be sequentially reproduced and synthesized.

  Here, based on the attack action of one character or a parameter (for example, physical strength value) set for the character, the output order of the first and second sounds and the synthesis ratio of the first and second sounds (first The ratio of the lengths of the two sounds and the ratio of the volume of the first and second sounds may be adjusted. For example, as shown in FIG. 14C, as the physical strength value or attack power of one character that has made an attack increases, the second sound (for example, armor sound) with respect to the length T3 of the first sound (for example, armor sound) The ratio (T4 / T3) of the length (T4) of the fabric sound) is increased, or the ratio (V2 / V1) of the volume V2 of the second sound to the volume V1 of the first sound is increased. May be. In this way, it is possible to express by sound that the weapon possessed by one character has penetrated the armor of the other character and arrived at the clothing of the fabric due to the high attack power or the like of one character.
