[Embodiment 1]
The game program described in the present embodiment is executed in a game device such as a personal computer, PlayStation (registered trademark), XBox (registered trademark), PlayStation Vita (registered trademark), or the like.

  In a game based on this game program, in response to the operation of each user, the player character is activated in a three-dimensional virtual game space, or a group of player characters is organized to perform various actions. When a predetermined trigger condition is satisfied in the movement process or action of the player character, game sound such as BGM flows. The predetermined trigger condition is, for example, movement of the player character to a predetermined place, appearance of an enemy character, after defeating an enemy character, and the like.

<Configuration of game device>
The game device 5 executes a predetermined game based on a user operation. FIG. 1 is a block diagram showing a configuration of the game apparatus 5 of the present embodiment. In the game apparatus 5, a display 61, a speaker 62, and a controller 63 are externally connected or built in. In the game device 5, for example, the game progresses based on the game program and game data installed in the storage unit 55. Note that the game devices 5 can also perform data communication with each other using a communication network (not shown) or a short-range wireless communication device (not shown).

  The game apparatus 5 includes a network interface 51, a graphic processing unit 52, an audio processing unit 53, an operation unit 54, a storage unit 55, and a control unit 56. The network interface 51, the graphic processing unit 52, the audio processing unit 53, the operation unit 54, and the storage unit 55 are electrically connected to the control unit 56 via the bus 59.

  The network interface 51 is communicably connected to a communication network in order to transmit / receive various data to / from the game device 5 and an external server device (not shown), for example.

  In accordance with the game image information output from the control unit 56, the graphic processing unit 52 draws a game image including various objects related to the player character and the game space in a moving image format. The graphic processing unit 52 is connected to the display 61, and the game image drawn in the moving image format is displayed on the display 61 as a game screen. Details of the graphic processing unit 52 will be described later.

  The audio processing unit 53 reproduces and synthesizes digital game sound in accordance with instructions from the control unit 56. The audio processing unit 53 is connected to the speaker 62, and the reproduced and synthesized game sound is output from the speaker 62. Details of the audio processing unit 53 will also be described later.

  The operation unit 54 is connected to the controller 63 and transmits / receives data related to operation input to / from the controller 63. For example, the user inputs an operation signal to the game apparatus 5 by operating an operator (not shown) such as a button provided in the controller 63.

  The storage unit 55 includes an HDD, a RAM, a ROM, and the like. The storage unit 55 can store a game program and game data. The storage unit 55 also stores other account information received from other game devices 5.

  The control unit 56 is composed of a microcomputer including a CPU and a semiconductor memory, and controls the operation of the device 5 itself. For example, the control unit 56 operates the graphic processing unit 52 and the audio processing unit 53 by executing the game program. In particular, the control unit 56 of the present embodiment controls, under the game program, at what timing on the screen the video expression described later is applied at which timing during the execution of the game program.

<Details of audio processor functions>
The audio processing unit 53 includes so-called middleware that plays a function of reproducing and synthesizing game sound. Here, the game sound is sound that flows from the speaker 62 during execution of the game program, and includes, for example, various sounds such as BGM (Back Ground Music) and sound effects that flow in response to a user operation.

  The audio processing unit 53 generates game sound (digital data) such as BGM. At that time, the audio processing unit 53 generates game sound data in accordance with a volume value (hereinafter referred to as a master volume value) instructed from the control unit 56 in advance. The audio processing unit 53 converts the generated audio data into an analog signal and outputs it to the speaker 62. Thereby, game sound is output (reproduced) from the speaker 62.

  The audio processing unit 53 outputs information related to the game sound to the graphic processing unit 52 in the process of generating the game sound. Specifically, the audio processing unit 53 outputs information indicating the master volume value (that is, the volume of the game sound) (hereinafter referred to as a volume parameter) to the graphic processing unit 52. The use of the volume parameter in the graphic processing unit 52 will be described later.

<Details of graphic processing section>
The display data generated by the graphic processing unit 52 under this game program is 3D moving image data. In order to generate the data of the 3D image, the graphic processing unit 52 includes so-called middleware that performs calculation of the positions of vertices constituting the object (displayed as a solid on the screen) and shading processing of the surface. It is out.

  For example, in the case of a battle-type action game in which a player character attacks and defeats an enemy character by this middleware function, the player character's attacking action, defensive action, etc. are activated during the execution of the game program. And three-dimensionally realized.

  In order to realize such dynamic and stereoscopic video display, the middleware includes a shader. For example, suppose that it is necessary to create a moving image with waves on the water surface during the execution of the game program. In this case, the graphic processing unit 52 uses this shader to calculate the vertex positions of the polygons constituting the object displayed as “rippling water surface”. Further, the graphic processing unit 52 adjusts the contrast of light and darkness of the object using this shader, and performs processing for giving the object a stereoscopic effect.

  The movement of the object during execution of such a game program is generally determined by the control unit 56 based on a user instruction (operation of the operation unit 54) or derived as a result of the user operation. is there. Further, during execution of the game program, game sound (BGM or sound effect) is output from the audio processing unit 53 as necessary. That is, generally, the movement of the object is based on the game image information from the control unit 56, and the game sound is reproduced in a form added thereto.

  The graphic processing unit 52 of the present embodiment realizes the “movement” (that is, video expression) of the object based on the game sound, in addition to such a general operation. Under this game program, there is an object (named movable object M) that is set to move in response to sound (sound wave) in the game space. It is up to the game program developer to decide which object in the game space is the movable object M.

  Under this game program, the graphic processing unit 52 moves the movable object M on the screen of the display 61 as described below, thereby realizing effective video expression.

  The graphic processing unit 52 uses a volume parameter as a material for determining the “movement” of the movable object M. The volume parameter is given from the audio processing unit 53. When the volume parameter is given, the graphic processing unit 52 obtains the amount (displacement amount) that each point on the movable object M moves. In this example, the graphic processing unit 52 makes the displacement amount of each vertex of the polygon constituting the movable object M proportional to the volume parameter.

  For example, when the water surface in the game space (the sea, the lake, etc. in the game space) is set as the movable object M, the graphic processing unit 52 uses the game sound (for example, a sound effect such as a character voice or explosion sound). ), The displacement amount of each vertex of the polygon is determined so that a wave having a wave height (proportional in this example) corresponding to the sound volume stands on the water surface.

  Next, the graphic processing unit 52 generates display data corresponding to the obtained displacement amount. Thereby, under this game program, a video expression in which the water surface (movable object M) is waved is performed in accordance with a change in sound.

  2 to 4 exemplify the movement of the water surface (movable object M) to which the video expression of the present embodiment is applied. 2 to 4 each show one frame of a moving image. Specifically, FIG. 2 shows a case where the volume of the game sound is relatively low, FIG. 3 shows a case where the volume is medium, and FIG. 4 shows a case where the volume is relatively high.

  As shown in FIG. 2 to FIG. 4, the larger the volume of the game sound, the larger the water surface that appears on the display 61. As described above, this embodiment is useful for representing a background image such as a water surface (such as a sea or a lake in a game space).

  In summary, the present invention shows the volume value of the game sound when the computer (game device 5) displays the movable object M, which is an object operable in the game space, on the display device (display 61). A game program that functions as display processing means (graphic processing unit 52) that operates the movable object in the game space with a size according to a volume parameter.

<Effect of this embodiment>
As described above, under this game program, the “movement” of the object can be created from the game sound. Therefore, according to the present embodiment, various expressions (video expressions) are possible in the game apparatus 5.

[Embodiment 2]
In the second embodiment, an example of a game program in which directivity can be added to the motion (video expression) of an object based on sound will be described. The hardware configuration of the present embodiment is the same as that of the first embodiment, but the functions of the control unit 56 and the graphic processing unit 52 are different from those of the first embodiment under the game program of the present embodiment. is there. Below, it demonstrates centering on difference with Embodiment 1. FIG.

<Details of control unit functions>
In the game program of the present embodiment, there is an object (hereinafter referred to as a sound source object S) that is handled as a sound source (that is, a virtual sound source) in the game space. Examples of the sound source object S include the player character itself, items (for example, weapons) possessed by the player character, devices arranged in the game space, and the like. It is up to the game program developer to select which object in the game space is the sound source object S.

  The control unit 56 outputs information on the distance (distance in the game space) between the sound source object S and the movable object M (hereinafter referred to as a distance parameter) in the game space to the graphic processing unit 52.

  Furthermore, the control unit 56 also displays an index (attenuation parameter) indicating how much the sound emitted from the sound source object S is attenuated (volume reduction) according to the distance between the sound source object S and the movable object M. Is output.

<Details of graphic processing section>
The graphic processing unit 52 increases the displacement amount of the vertex closest to the sound source object S among the vertexes of the polygon constituting the movable object M and minimizes the displacement amount of the vertex farthest from the sound source object S. Determine the amount of displacement at each point. FIG. 5 illustrates the movement (that is, the wave) of the water surface (movable object M) to which the video expression of the present embodiment is applied. FIG. 5 shows one frame of a moving image.

  In order to realize the movement shown in FIG. 5, the graphic processing unit 52 uses a distance parameter and an attenuation parameter as a material for determining the “movement” of the movable object M in addition to the volume parameter. The volume parameter is obtained from the audio processing unit 53. Here, the volume parameter is used to indicate the volume of the sound that is assumed to be emitted from the sound source object S.

  Receiving these parameters, the graphic processing unit 52 calculates the displacement amount of each point on the movable object M. Using the distance parameter and the attenuation parameter, the graphic processing unit 52 calculates the volume (volume attenuated according to the distance) at each point (for example, the vertex of the polygon) on the movable object M, and sets each volume according to the volume. Calculate the displacement of the point. Specifically, the graphic processing unit 52 increases the displacement amount of the point corresponding to the volume as the calculated volume increases.

  For example, in the example of FIG. 5, when the distances from the sound source object S are compared for the points P0, P1, P2, and P3 on the movable object M, (distance d0 to point P0) <(distance to point P1) d1) <(distance d2 to point P2) <(distance d3 to point P3). Then, the displacement amount of these points P0, P1, P2, P3 is the relationship of (displacement amount of point P0)> (displacement amount of point P1)> (displacement amount of point P2)> (displacement amount of point P3). It becomes.

  In the example of FIG. 5, the amount of displacement is zero as a result of the sound from the sound source object S being attenuated at the point P3 and its surroundings. That is, depending on the relationship between the volume parameter, the attenuation parameter, and the distance parameter, there may be a portion on the movable object M that does not move at all.

<Effect of this embodiment>
As described above, the “movement” of an object can be created from the game sound even under the game program of the present embodiment. In addition, in the present embodiment, since the attenuation parameter and the distance parameter are taken into consideration in addition to the volume parameter, the video expression becomes more versatile. That is, also in this embodiment, various expressions can be made in the game apparatus 5.

[Other Embodiments]
Note that the frequency of the game sound may be taken into account in calculating the displacement amount. For example, it is conceivable that the audio processing unit 53 extracts a predetermined frequency range from the game sound and obtains a displacement amount based on the volume of each frequency range.

  For calculating the displacement amount, all game sounds generated in the game may be used, or only a specific game sound may be used. For example, by using only the voice uttered by a specific character for calculating the displacement, the player's attention can be drawn to the utterance of the character.

  Further, the color information of the vertices constituting the movable object may be changed according to the game sound. As a result, an expression in which the color of the object changes depending on the volume can be achieved.

  Moreover, the water surface mentioned as a movable object is an illustration. The present invention can also be applied to other movable objects. For example, the present invention may be applied to an object representing grass, hair, raindrops, snow, or the like.

  In the second embodiment, instead of the distance parameter, the position information of the sound source object S and the position information of the movable object M are given to the graphic processing unit 52, and the volume ( That is, the displacement amount of the object) may be obtained.

  The game program may be configured to pause the video expression according to the embodiment according to the game situation.

  The game program may be implemented as a game program for so-called online games. When the game program is for an online game, the processing in the graphic processing unit 52 and the control unit 56 may be performed on the server side, or may be shared between the server side and the client (game device 5) side. .

  Even when these other embodiments are employed, the effects of the present invention are exhibited. In addition, this embodiment, other embodiments, and other embodiments can be appropriately combined.
