Abstract

<P>PROBLEM TO BE SOLVED: To enhance players' involvement in games with higher virtuality of the games using a plurality of sound sources by varying the plurality of sound sources installed within a game space and the respective sound volumes based on the relative orientations to the respective sound sources from a virtual camera on a basis of the visual direction of the virtual camera. <P>SOLUTION: The output sound volumes of the respective sound sources are varied based on the relative orientations to the respective sound sources from the virtual camera CM on a basis of the visual direction of the virtual camera. In other words, the relative orientations are determined from a relative angle between the visual direction M and the respective sound sources centering around the virtual camera CM in the game space and the directions of the respective sound sources are divided into front, side and rear zones according to the relative orientations obtained. The output sound volumes of the respective sound sources are thus controlled by the divided directional zones. For example, the output sound volumes are set larger in the order of the sound source O17 behind the virtual camera CM, the sound source O15 beside it and the sound sources O11 and O13 before it. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

[Configuration of game device]
FIG. 1 is a diagram illustrating an example of a device configuration when the game device according to the present embodiment is applied to a consumer game machine 1200. A home game machine 1200 shown in FIG. 1 includes a game controller 1210, a main device 1220, and a display 1230 having a speaker 1232. The game controller 1210 is connected to the main device 1220, and the display 1230 is connected to the main device 1220 by a cable capable of transmitting image signals, sound signals, and the like.

  The game controller 1210 is for a player to input a game operation. The game controller 1210 includes a direction key 1212, an operation button 1214, and the like, and outputs an operation signal to the main body device 1220.

  In this consumer game machine 1200, information storage such as a CD-ROM or DVD, which is an information storage medium detachably attached to the main unit 1220, is used as an information storage medium for storing programs and data necessary for executing game processing. A medium 1240 is used. Alternatively, the game program and game data may be acquired from an external device by connecting to the communication line N via the communication device 1224 provided in the main body device 1220. The communication line N mentioned here means a communication path through which data can be exchanged. That is, the communication line N is meant to include a communication network such as a telephone communication network, a cable network, and the Internet in addition to a LAN using a dedicated line (dedicated cable) for direct connection or Ethernet (registered trademark). The communication method is meaning regardless of wired / wireless.

  On the other hand, an information storage medium such as a memory card 1252 or an IC card 1254 is used as an information storage medium to which data including information related to the progress of the game is written in accordance with a predetermined timing during the game or a save operation by the player.

  The main unit 1220 includes a control unit 1222 equipped with a CPU and IC memories, a reading device for an information storage medium 1240 such as a CD-ROM, and the like, a program and data read from the information storage medium 1240, and a game controller. Various game processes are executed based on an operation signal or the like input from 1210, and an image signal of a game screen and a sound signal of a game sound are generated. Then, the image signal and the sound signal are output to the display 1230, the game image is displayed on the display 1230, and the game sound is output from the speaker 1232. In the present embodiment, an image of a game space in which objects such as characters such as a ground, a ball, a player (a pitcher, a catcher, a fielder, a runner, a batter) and a coach are arranged is displayed on the display 1230 as a game screen.

  The player operates the game controller 1210 while viewing a game image displayed on the display 1230, and enjoys a baseball game by playing against an opponent (computer or other player). In the following, it is assumed that a player team operated by a player and a computer-controlled COM team play a battle.

[principle]
In the present embodiment, various sound sources are set in the game space, and sounds generated from the sound sources are output as game sounds during the game. As a specific example, for example, a sound source that generates voices and footsteps of a character (moving body) such as a player or a coach is set. Alternatively, a sound when the ball (moving body) is caught (hereinafter referred to as “catch sound”) or a sound when the ball is hit with a bat (hereinafter referred to as “hitting sound”). A sound source that generates a sound at the time of collision with the fence (hereinafter referred to as “fence collision sound”) is set.

  Each sound source set in the game space is roughly classified into three types of sound sources: a defensive sound source, an attacking sound source, and other sound sources. As the defensive sound source, for example, a sound source set for the defensive character is prepared. As the attacking sound source, for example, a sound source set for the attacking character is prepared. As other sound sources, for example, a ball sound source set for a ball is prepared. Although details will be described later, the sound generated from each sound source is prepared in correspondence with the generation condition, and when the current game progress is in a scene that satisfies the generation condition, the corresponding sound is It is generated as a sound.

  FIG. 2 is a schematic view overlooking the ground set in the game space. In the scene of FIG. 2, the fielder's line “Orai, Allai” is generated as the sound of the sound source from the sound source set to the fielder Cf, and the sound of the sound source is set to 3 音源 from the sound source set to the 3rd coacher Cc. The coacher's dialogue “Mamare, Mamare!” Is generated, and the sound of the sound source from the sound source set to the runner Cr is “Tata Tatata” which is a running sound (footstep).

  In the present embodiment, processing (sound output control processing) is performed in which output control is performed by superimposing sounds generated from a plurality of sound sources. At this time, the output volume of each sound source is (1) a relative orientation from the virtual camera CM to the sound source with reference to the line-of-sight direction of the virtual camera CM, (2) a relative distance between the virtual camera CM and the sound source, And (3) controlled according to the offense and defense of the player team.

(1) Relative direction The relative direction from the virtual camera CM to the sound source with respect to the visual line direction of the virtual camera CM so that the output volume of each sound source decreases as the sound source moves away from the visual line direction of the virtual camera CM. Is variable based on

  FIG. 3 is a diagram for explaining the principle of output volume control based on the relative direction. In the present embodiment, the relative direction is determined by the relative angle between the line-of-sight direction M and the sound source with the virtual camera CM in the game space as the center, and according to this relative direction, the sound source is in front, side, Divided into rear direction segments. Then, the output volume of the sound source is controlled in three stages according to the divided direction sections.

  The direction division is defined by the angle of view of the virtual camera CM in the game space, for example. In particular, the range included in the angle of view of the virtual camera CM is the front. FIG. 3 is a diagram when the angle of view of the virtual camera CM is in the range of 0 ° to ± θw relative to the viewing direction M of the virtual camera CM, and the corresponding area is the front. Note that the method of division is not limited to this, and it is of course possible to divide into smaller direction divisions.

  Furthermore, in the present embodiment, in the range included in the angle of view of the virtual camera CM that is set as the front, the output volume is set to be larger than the other part in the range (see, for example, a virtual area indicated by hatching in FIG. 3) A relative angle of the camera CM with the line-of-sight direction M is defined within a range of 0 ° to ± (θw / 3)).

  That is, in the example of FIG. 3, the output sound volume is controlled in the order of the sound source O17 divided behind the virtual camera CM, the sound source O15 divided sideward, and the sound sources O11 and O13 divided forward. The For the sound sources O11 and O13 that are divided in front of the virtual camera CM, the output volume of the sound source O11 in the special area is controlled to be larger than the output volume of the sound source O13 outside the special area. .

  In this way, the output volume of the sound source set in the game space is reduced from the virtual camera CM based on the visual line direction of the virtual camera CM so that the sound source decreases as the sound source moves away from the visual line direction of the virtual camera CM. It can be varied based on the relative orientation to the sound source. Specifically, the output sound volume can be set to increase in the order of the sound source behind the virtual camera CM, the sound source that is the side, and the sound source that is the front. At this time, since the range included in the angle of view of the virtual camera CM is set to the front, the output volume of the sound source within the visual field of the virtual camera CM can be set larger than the output volume of the sound source outside the visual field. .

  Therefore, for the player, all sounds generated from the sound source set in the game space can be heard, but the sound of the sound source in front of the virtual camera CM can be heard strongly and well. Furthermore, among the sound sources in front of the virtual camera CM, the sound of the sound source in the special area can be heard more strongly and better.

(2) Relative distance The output volume of each sound source is varied based on the relative distance between the virtual camera CM and the sound source so that the sound source becomes smaller as the sound source becomes farther from the virtual camera CM.

  FIG. 4 is a diagram for explaining the principle of output volume control based on relative distance. In the present embodiment, based on the relative distance from the virtual camera CM to the sound source in the game space, the sound source is divided into short distance, middle distance, long distance, and out-of-range distance centers around the virtual camera CM. . Then, the output volume of the sound source is controlled in four steps according to the divided distance sections.

  That is, in the example of FIG. 4, the output volume of the sound source O21 divided into short distances is controlled to be larger than the output volume of the sound source O23 divided into medium distances.

  Thus, the output volume of the sound source set in the game space can be varied based on the relative distance between the virtual camera CM and the sound source so that the sound source becomes smaller as the sound source becomes farther from the virtual camera CM. Specifically, the output volume can be set in the order of a sound source that is out of range centered on the virtual camera CM, a sound source that is a long distance, a sound source that is a medium distance, and a sound source that is a short distance.

(3) Offense and defense on the player team side The output volume of each sound source can be varied according to the offense and defense on the player team side. Specifically, when the offense and defense on the player team side is the defensive side, the output volume of the defensive sound source is set larger than the output volume of the attacking sound source. On the other hand, when the offense and defense on the player team side is the attacking side, the output volume of the attacking sound source is set larger than the output sound volume of the defensive sound source.

  For example, in the game scene shown in FIG. 2, when the offense and defense on the player team side is the defensive side, the dialogue generated from the sound source set in the fielder Cf is the dialogue generated from the sound source set in the 3rd coacher Cc. As compared with the running noise generated from the sound source set to the runner Cr, the sound is output at a larger volume. On the other hand, when the offense and defense of the player team is the attacking side, the line generated from the sound source set in the 3rd coacher Cc and the running sound generated from the sound source set in the runner Cr are set in the fielder Cf. The sound is output at a louder volume than the dialogue generated from the sound source.

  In this way, when the offense and defense on the player team side is the attack side, the output volume of the attacking sound source can be set high, and when the offense and defense side is on the defense side, the output volume of the defensive sound source can be set high.

Here, a specific method for calculating the output volume will be described. The output volume calculation formula (1) is shown below.
Output volume = p × d × s × B (1)
Here, p is a direction coefficient, d is a distance coefficient, s is an offense and defense coefficient, and B is a reference volume.

<Direction coefficient (p)>
The direction coefficient (p) is defined by the angle of view of the virtual camera CM (the relative angle with the viewing direction of the virtual camera CM is in the range of 0 ° to ± θw) as described with reference to FIG. -It is preset for each rear direction section, and the direction coefficient (p) is determined depending on which direction section the sound source belongs to.

  FIG. 5 is a diagram illustrating an example of a correspondence relationship between a direction segment and a direction coefficient (p). As shown in FIG. 5, the direction coefficient (p) is set stepwise for each direction segment so that the value decreases as the sound source moves away from the line-of-sight direction of the virtual camera CM. Further, the value of the direction coefficient (p) with respect to the front is defined by a function that becomes larger when the angle of view of the virtual camera CM is narrower than when it is wide. Thereby, the output volume of the sound source divided forward when the angle of view of the virtual camera is narrow is varied so as to be larger than the output volume of the sound source divided forward when it is wide.

<Distance coefficient (d)>
The distance coefficient (d) is set in advance for each of the short distance, medium distance, long distance, and out-of-range distance categories centered on the virtual camera CM described with reference to FIG. The distance coefficient (d) is determined depending on whether it belongs.

  FIG. 6 is a diagram illustrating an example of a correspondence relationship between a distance category and a distance coefficient (d). As shown in FIG. 6, the distance coefficient (d) is set stepwise for each distance section so that the sound source becomes smaller as the sound source becomes farther from the virtual camera CM.

<Offense and defense coefficient (s)>
In the present embodiment, the offense / defense coefficient (s) for each sound source type is set in advance for each offense / defense on the player team side, and the offense / defense coefficient (s) is determined depending on whether the offense / defense on the player team side is the attack side or the defensive side. Is done.

  FIG. 7 is a diagram illustrating an example of a correspondence relationship between the sound source type and the offense / defense coefficient (s). As shown in FIG. 7, when the player team is on the defensive side, the offense / defense coefficient (s) is set so that its value decreases in the order of the defensive sound source, the other sound sources, and the attacking sound source. In the case of the attacking side, the values are set so that the values decrease in the order of the attacking sound source, the other sound sources, and the defensive sound source.

<Reference volume (B)>
The reference volume (B) is a volume that serves as a reference for the sound source, and is set in advance. The volume of the sound source itself is adjusted according to the value of the reference volume (B). Therefore, for example, if the reference volume (B) of the sound related to the ball, such as a catch sound, is set to a value larger than the reference volume (B) of another sound source, the ball is caught behind the virtual camera CM. Even so, it is possible to output the catch sound of the ball with a relatively loud sound.

The player enjoys the game by operating the operation unit 100 while viewing the game image displayed on the display unit 300.

  The sound output unit 400 is a device for outputting sound of a sound source, sound effects, BGM, and the like based on a sound signal input from the sound generation unit 260, and the speaker 1232 corresponds to this in FIG.

  The communication unit 500 performs data communication with the outside via a communication line. The function of the communication unit 500 is realized by, for example, a wireless communication module, a modem, a TA, a wired communication cable jack, a control circuit, and the like.

  The storage unit 600 stores a system program for causing the processing unit 200 to control the game apparatus 1 in an integrated manner, and a program and data necessary for executing the game. The functions of the storage unit 600 are realized by, for example, an IC memory, a hard disk, a memory card, and the like. In FIG. 1, the IC mounted on the information storage medium 1240, the memory card 1252, the IC card 1254, and the control unit 1222 Such as memory.

  In particular, a game program 610 is stored in the storage unit 600 in order to realize the present embodiment. The game program 610 functions as a virtual camera control program 611 for causing the processing unit 200 to function as the virtual camera control unit 221, a sound source setting program 613 for causing the processing unit 200 to function as the sound source setting unit 223, and a sound output control unit 225.

  Character information 620 stores information on characters such as players and coaches appearing in the baseball game for each team. Information related to the character includes the values of various parameters set for the character, model data for displaying the character, object data such as texture data, motion data, and the current position coordinates on the ground. . Further, when the character is a player, information on the position of the player is further included, and is referred to when the sound source setting unit 223 sets the sound source.

  The speech data 630 stores speech data of speech uttered by characters appearing in the baseball game. FIG. 9 is a diagram illustrating a data configuration example of the dialogue data 630. As shown in FIG. 9, speech data of speech associated with speech identification numbers is stored as speech data 630, for example, as a WAV file. When the line identification number is read out as the sound of the sound source in accordance with sound source information 640 described later, the sound output control unit 225 reads out the corresponding audio data from the line data 630 and causes the sound output unit 400 to output it.

  The sound source information 640 stores a plurality of sound source data set in the game space by the sound source setting unit 223. Specifically, for each sound source type, the setting position, generation condition, sound data, and reference volume (B) of the sound source are set.

  FIG. 10 is a diagram illustrating a data configuration example of the sound source information 640. In the present embodiment, the sound source type of each sound source is roughly divided into three types, that is, a defensive sound source, an attacking sound source, and other sound sources as described above. A sound source or the like set for the attacking character is set as the attacking sound source, and a ball sound source or the like set for the ball is set as the other sound source.

  The generation conditions include a scene condition that is a game scene for generating the sound of the sound source and the corresponding motion, and for the sound source set for the character, the corresponding motion is appropriately set as the generation condition. If the corresponding motion is set, the current game progress is in a scene that satisfies the corresponding scene condition, and the condition is that the character at the sound source position has started the corresponding motion. Will be generated.

  In the sound data, the sound of the sound source is set. If the character for which the sound source is set generates a line when the corresponding generation condition is satisfied, the line identification number of the generated line is set. The speech data itself is stored in the speech data 630 as described above. In FIG. 10, the content of the dialogue is shown in parentheses.

  For example, when a fly is caught by a fielder and the fielder starts a motion ready to catch the fly, the sound output of the line “Orai, Allai” is output as the sound of the sound source set for the fielder Is controlled (record L11). Alternatively, in the scene where the ball is caught, the sound output of the catch sound is controlled as the sound of the sound source set on the ball (record L13).

  As the reference volume (B), a volume serving as a reference for the sound source is set. As described above, the actual output volume is determined based on this reference volume (B).

  The sound source setting unit 223 refers to the sound source information 640 and sets each sound source in the game space according to the set position.

  In addition, the sound output control unit 225 refers to the sound source information 640 and executes sound output control processing. Specifically, when there is a sound source whose game scene matches the generation condition, the sound output control unit 225 first executes the following processing for each of the matching sound sources. That is, the sound output control unit 225 executes a process for determining the direction coefficient (p), a process for determining the distance coefficient (d), and a process for determining the offense / defense coefficient (s), and sets the corresponding reference volume (B). Originally, the output sound volume of the sound source is set according to each determined coefficient. Then, the sound output control unit 225 performs control to superimpose and output the sound of each sound source determined to be matched according to the set output volume.

The sound output control coefficient information 650 includes a direction coefficient table 651, a distance coefficient table 653, and an offense / defense coefficient table 655.

  The direction coefficient table 651 stores the correspondence between the relative direction from the virtual camera CM to the sound source and the direction coefficient (p) with reference to the viewing direction of the virtual camera CM. Specifically, as shown in FIG. 5, the corresponding direction coefficient (p) is set in association with the direction segment based on the relative direction.

  The distance coefficient table 653 stores the correspondence between the relative distance between the virtual camera CM and the sound source and the distance coefficient (d). Specifically, as shown in FIG. 6, the corresponding distance coefficient (d) is set in association with the distance classification based on the relative distance.

  The offense / defense coefficient table 655 stores the offense / defense coefficient (s) corresponding to the sound source type. Specifically, as described with reference to FIG. 7, the offense / defense coefficient (s) for each sound source type is set for each offense / defense on the player team side.

  The current virtual camera data 660 updates and stores the setting values of the position coordinates, the line-of-sight direction, and the angle of view of the virtual camera CM controlled by the virtual camera control unit 221 as needed.

[Process flow]
Next, with reference to FIG.11 and FIG.12, the game process in this embodiment is demonstrated. Note that the processing described below is realized by the processing unit 200 reading and executing the game program 610 including the virtual camera control program 611, the sound source setting program 613, and the sound output control program 615.

  FIG. 11 is a flowchart for explaining the flow of the game processing in the present embodiment. In the game process, first, as a preparatory stage before starting the game, the game calculation unit 220 arranges an object such as a ground, a ball, and a player character, and a virtual camera CM in the game space and performs an initial setting (step s10). . At this time, the current virtual camera data 660 is initialized with the set values of the position coordinate, the line-of-sight direction, and the angle of view of the arranged virtual camera CM.

  Subsequently, the game calculation unit 220 executes a game progress process (step s20). This game progress process is a process related to the progress of the baseball game, and can be executed in the same manner as a conventional baseball game, and thus detailed description thereof is omitted here.

  Next, the virtual camera control unit 221 executes a virtual camera control process according to the current game progress status (step s25). Specifically, the virtual camera control unit 221 includes at least one of the position, the line-of-sight direction, and the angle of view of the virtual camera CM so that a predetermined moving body such as a ball or a player's operation target character is within the field of view. And the current virtual camera data 660 is updated.

  Next, the sound source setting unit 223 refers to the sound source information 640 and sets a sound source in the game space based on the result of the game progress process in step s20 (step s30). At this time, processing for changing the character for setting each sound source is performed by reflecting offense and defense substitution, player substitution, and the like.

  Subsequently, the sound output control unit 225 executes sound output control processing (step s40). FIG. 12 is a flowchart for explaining the flow of the sound output control process.

  In the sound output control process, the sound output control unit 225 first determines the presence or absence of a sound source whose game scene matches the generation condition according to the current game progress. If there is a sound output control unit 225 (step s401: YES), the sound output control unit 225 executes the process of loop A for all the sound sources determined to match (step s403 to step s419). Hereinafter, the sound source to be processed in the loop A is referred to as “this sound source”.

  In the loop A, the sound output control unit 225 first calculates a relative direction from the virtual camera CM to the sound source with reference to the current line-of-sight direction of the virtual camera CM (step s405). Then, the sound output control unit 225 refers to the direction coefficient table 651 and determines the direction coefficient (p) based on the relative direction calculated in step s405 (step s407).

  Next, the sound output control unit 225 calculates the relative distance between the current virtual camera CM and the sound source (step s409). Then, the sound output control unit 225 refers to the distance coefficient table 653 and determines the distance coefficient (d) based on the relative distance calculated in step s409 (step s411).

  Next, the sound output control unit 225 determines whether the player team is a defense side or an attack side (step s413). Then, the sound output control unit 225 refers to the offense / defense coefficient table 655 and determines the offense / defense coefficient (s) based on the offense / defense of the player team determined in step s413 and the sound source type of the sound source (step s415). .

  Then, the sound output control unit 225 sets the output volume of the sound source according to the coefficients determined in steps s407, s411, and s415 based on the reference volume (B) of the sound source (step s417). That is, the sound output control unit 225 calculates the output sound volume by substituting each coefficient determined in the above calculation formula (1) and the reference sound volume (B) of the sound source.

  When the loop A is completed, the sound output control unit 225 performs control to superimpose and output the sound of each sound source that is determined that the game scene matches the generation condition in step s401 according to the output volume set in step s417. Perform (step s421).

  Returning to FIG. 11, when the sound output control process is ended, the game calculation unit 220 determines whether or not the game end condition of the baseball game is satisfied. If it is determined that the game end condition is not satisfied (step s50: NO), the game calculation unit 220 proceeds to the above-described game progress process (step s20) and repeats the above-described process.

  In addition, when the game end condition is satisfied (step s50: YES), the game calculation unit 220 displays the game result (step s60) and ends the process.

[Modification]
The preferred embodiments of the present invention have been described above, but the present invention is not limited to those described above, and can be changed as appropriate without departing from the spirit of the invention.

  For example, in the above-described embodiment, as illustrated in FIG. 3, in the range included in the angle of view of the virtual camera CM, the special area in which the output volume is set larger than the other part in the range is set as the virtual camera. The relative angle of the CM to the line-of-sight direction M is, for example, in the range of 0 ° to ± (θw / 3), but may be as follows.

  That is, the special area may be set based on the position of a predetermined moving body such as a ball or a player's operation target character included in the visual field of the virtual camera CM. As a specific example, for example, an area in which a relative angle between a virtual camera CM in the game space and a line segment connecting the virtual camera CM and the predetermined moving body is within a predetermined range is set as a special area. It is good as well.

  Or it is good also as setting the area | region within the predetermined range centering | focusing on the said predetermined moving body contained in the visual field of virtual camera CM as a special area.

  FIG. 15 is a diagram for explaining a modified example of the special area defined within the range included in the angle of view of the virtual camera CM. In the example shown in FIG. 15, a region E11 centered on the ball B within the range included in the angle of view of the virtual camera CM and a region E13 centered on the operation target character PC are set as special regions. According to this, the output volume of the sound source in the areas E11 and E13 centering on the ball B and the operation target character PC included in the visual field of the virtual camera CM is within the range included in the angle of view of the virtual camera CM. It can be variably set so as to be larger than the output volume of the sound source in the other part.

  In the above-described embodiment, the case has been described in which the direction coefficient (p) is set so that the output sound volume increases in the order of the sound source behind the virtual camera CM, the sound source that is the side, and the sound source that is the front. The following may be used. That is, for example, the direction coefficient (p) may be set so that the output volume of the sound source behind the virtual camera CM is larger than the output volume of the sound source that is in front or side. Similarly, the direction factor (p) may be set so that the output volume of the sound source that is on the side of the virtual camera CM is larger than the output volume of the sound source that is in front or behind.

  In the embodiment described above, the range included in the angle of view of the virtual camera CM is defined as the front. However, the range in which the relative angle with the line-of-sight direction of the virtual camera CM is narrower than the angle of view is defined as the front. It may be defined. Alternatively, a range in which the relative angle with the viewing direction of the virtual camera CM is wider than the angle of view may be defined as the front.

  In addition, when setting a sound source for each character, a parameter indicating the volume of voice is set in advance for each character, and the output volume of the sound source set for the character is set according to the value of this parameter. Further, it may be set variably.

  In the above-described embodiment, the direction coefficient (p) set in advance for each of the front, side, and rear direction sections of the virtual camera CM, and the short distance, medium distance, long distance, and out-of-range distance from the virtual camera CM. Although the distance coefficient (d) set for each section is determined and the output volume of each sound source in the game space is varied, the following may be used.

  FIG. 16 is a diagram for explaining a modified example of the output sound volume control. FIG. 16A is a diagram schematically showing a volume control coefficient table that is referred to when determining the volume control coefficient used in this modification, and the value of the volume control coefficient for each 5 × 5 cell is shown. Is set. Specifically, the value of the volume control coefficient set in the center cell M11: 1.5 is set as the maximum, the value set in the front cell, the value set in the side cell, and the value set in the rear cell. The value of the volume control coefficient is set in each cell so that the value of the volume control coefficient becomes smaller in the order of the values, and the value of the volume control coefficient set in the cell farther from the central cell M11 becomes smaller. Yes.

  On the other hand, as shown in FIG. 16B, the game field is divided into a plurality of blocks in advance. When a sound source belonging to any of the 5 × 5 blocks centered on the block to which the virtual camera CM arranged in the game space generates sound, the volume control coefficient of the block to which the sound source belongs is This is determined with reference to the volume control coefficient table. At this time, it is determined whether the viewing direction of the virtual camera CM belongs to the up, down, left, or right direction toward FIG.

  For example, consider the case where the virtual camera CM is arranged with the line-of-sight direction as M11 in the block B11 shown in FIG. 16B, and the sound source that is the target of output volume control is arranged in the block B13. First, it is determined that the line-of-sight direction M11 of the virtual camera CM belongs to the upward direction in FIG. Subsequently, the volume control coefficient table in FIG. 16A is referred to, and the virtual camera CM is defined with the upper direction to which the line-of-sight direction M11 of the virtual camera CM belongs as the front and the block M11 to which the virtual camera CM belongs as the center cell M11. The cell M13 that matches the relative positional relationship of the block B13 to which the reference sound source belongs is obtained, and the value of the cell M13: 0.9 is determined as the value of the volume control coefficient.

  Also, consider the case where the virtual camera CM is arranged with the line-of-sight direction as M21 in the block B21 and the sound source that is the target of the output volume control is arranged in the block B23. First, it is determined that the line-of-sight direction M21 of the virtual camera CM belongs to the downward direction in FIG. Subsequently, the volume control coefficient table of FIG. 16A is referred to, and the virtual camera CM is defined with the lower direction to which the line-of-sight direction M21 of the virtual camera CM belongs as the front and the block M21 to which the virtual camera CM belongs as the center cell M11. The cell M15 that matches the relative positional relationship of the block B23 to which the reference sound source belongs is obtained, and the value of the cell M15: 0.5 is determined as the value of the volume control coefficient.

  In addition, during the game, audience sounds such as cheering, cheering, and yaji may be output at a predetermined volume as other sound source types. In that case, the output volume of the spectator sound is variably set to be smaller than the output volume of the sound source other than the spectator sound, and the output is controlled by superimposing the spectator sound on the sound of the sound source other than the spectator sound. Also good.

  In the above-described embodiment, a case has been described in which the virtual camera control unit 221 controls the virtual camera CM so that a predetermined moving body such as a ball or a player character is within the field of view. Of course, the present invention can also be applied to the case where the virtual camera CM is controlled such that a game screen is generated from a first person viewpoint when the game space is viewed from the viewpoint of the target character.

  Alternatively, the virtual camera control unit 221 may arrange the virtual camera CM so as to look down slightly from above and behind the operation target character, and control the arrangement position so as to follow the operation target character. That is, the operation target character moves according to the operation input of the player, and the line-of-sight direction of the operation target character is controlled.

  In this case, the sound output control unit 225 may change the output volume based on the line of sight of the operation target character. For example, the sound output control unit 225 uses the line-of-sight direction of the operation target character as a reference so that the output volume of the sound source set in the game space decreases as the sound source moves away from the line-of-sight direction of the operation target character. It changes based on the relative direction from the operation target character to the sound source. Specifically, the sound output control process is performed by replacing the line of sight of the virtual camera CM in the above-described embodiment with the line of sight of the operation target character. At this time, the sound output control unit 225 sets the range that enters the field of view of the operation target character (for example, the range defined as the front in FIG. 5) to the front, and the output volume of the sound source that enters the view of the operation target character enters the view. Set it higher than the output volume of the sound source that does not exist.

  In this case, the player can hear all the sounds generated from the sound source set in the game space, but the sound of the sound source in front of the line of the operation target character that he / she moves and operates the line of sight can be heard strongly and well. Thus, apart from the displayed game screen, an actual feeling / immersion interval that the operation target character is operated is given.
