Description

  The present invention relates to a video game processing device and a video game processing program for outputting a listening sound in a virtual acoustic space in which a space effect affecting sound is set.

  2. Description of the Related Art Conventionally, a system for outputting a sound (listening sound) according to a sound source and a listening position (for example, a position of a player character in a video game) in a virtual space (particularly a virtual acoustic space or a virtual acoustic space) is known. It has been.

  As a technology related to such a system, for example, based on information on an object such as a wall in a three-dimensional virtual space, information on a sound source, and the progress of the game, the sound reaching the player's position is calculated and calculated. There is one that assigns sound to a plurality of speakers in order to output the sound obtained from the calculation result (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 06-149275

  In such a system, when moving from one virtual acoustic space where the listening position is located to another virtual acoustic space (that is, at the time of transition of the virtual acoustic space), a change (fade) with time after passing the change point of the acoustic environment is performed. It was. However, in the conventional system, the player character executes a behavior that cannot be dealt with by the change with time after passing through the change point, such as “when the player character moving in the virtual acoustic space stops immediately after passing through the change point”. In some cases, there was a problem that unnaturalness was conspicuous. In other words, when the listening position can be arbitrarily moved between a plurality of virtual acoustic spaces with different effects on sound, the change in the listening sound when moving from one virtual acoustic space to another virtual acoustic space is not significant. There was a problem of becoming natural.

  An object of the present invention is to solve the above-described problems and make a change in listening sound natural according to a change in listening position.

  The video game processing apparatus of the present invention is a video game processing apparatus that outputs a listening sound in a virtual acoustic space in which a spatial effect that affects sound is set, and is a part of a boundary constituted by at least two virtual acoustic spaces Or a determination means for determining whether or not a listening position is located in the transition area based on transition area information in which transition areas including all and transition effects affecting the spatial effect are associated with each other, and the listening position And a listening sound specifying means for specifying the listening sound based on a transition effect corresponding to the transition area.

  The acoustic spatial information includes a spatial effect value in which the contents of the spatial effect such as reverberation rate and attenuation rate are quantified, and the transition region information is a rule for calculating a transition effect value in which the content of the transition effect is quantified. The listening sound specifying means may be configured to specify the listening sound based on the spatial effect value and the transition effect value calculated according to the calculation rule.

  The spatial effect value and the transition effect value are in the same unit system, and the transition area information includes a lower limit footing value when the transition effect value is subtracted from the spatial effect value, and the listening sound specifying means includes Subtracting means for subtracting the transition effect value from the spatial effect value, and when the subtraction result by the subtracting means satisfies a predetermined update condition for the lower limit footing value, the subtraction result is the lower limit footing value. And a subtraction result update means for updating to the same value, and the listening sound may be specified based on the subtraction result updated by the subtraction result update means.

  Furthermore, the video game processing program of the present invention is a video game processing program for causing a computer to realize a function of outputting a listening sound in a virtual acoustic space in which a spatial effect that affects sound is set. The listening position is located in the transition region based on transition region information in which a transition region including a part or all of a boundary constituted by at least two virtual acoustic spaces and a transition effect that affects the spatial effect are associated with each other. In order to realize a determination function for determining whether or not to perform and a listening sound specifying function for specifying the listening sound based on a transition effect corresponding to the transition area when the listening position is located in the transition area belongs to.

  According to the present invention, the change in the listening sound according to the change in the listening position can be made natural.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an example of the configuration of a video game processing apparatus 100 according to an embodiment of the present invention. As shown in FIG. 1, the video game processing apparatus 100 includes a game program reading unit 10, a control unit 11, a storage unit 12, a display unit 13, an audio output unit 14, and a player operation reception unit 15.

  The game program reading unit 10 removably receives a game cartridge 20 containing a storage medium in which a game program is stored. The game program reading unit 10 reads a necessary game program from the storage medium of the inserted game cartridge 20.

  In this embodiment, it is assumed that the video game program classified as RPG is stored in the storage medium built in the game cartridge 20. However, the genre to which the video game program stored in the storage medium built in the game cartridge 20 belongs is not limited to RPG, and can be applied to various genres such as a simulation game.

  The control unit 11 has a function of executing the game program read by the game program reading unit 10 and executing various controls for advancing the video game in accordance with the operation of the player.

  The storage unit 12 is a storage medium that stores a game program and various data necessary for a video game to proceed. The storage unit 12 is configured by a nonvolatile memory such as a RAM, for example. The storage unit 12 stores various types of information registered and updated as the game progresses (including a set of data that is updated as appropriate and a set of basic data that is not allowed to be updated), and a memory built in the game cartridge 20. Various information used in the game read from the medium is stored. The information stored in the storage unit 12 will be described in detail later.

  The display unit 13 is a display device that displays a game screen according to the progress of the game or the player operation in accordance with the control of the control unit 11. The display unit 13 is configured by a liquid crystal display device, for example. In this example, a game screen representing the virtual space is displayed, and the acoustic space is not displayed. However, the acoustic space may be displayed as a game screen.

  The sound output unit 14 outputs a sound such as a sound based on the acoustic information stored in the acoustic information storage unit 12a that is updated in accordance with the progress of the game or the player operation according to the control of the control unit 11. In this example, a case where a known 5.1 channel surround system is used as the audio output unit 14 will be described as an example.

  The player operation receiving unit 15 receives an operation signal corresponding to a player operation from a controller configured by a plurality of buttons, a mouse, and the like, and notifies the control unit 11 of the result.

  Next, in order to describe various information stored in the storage unit 12 of the video game processing apparatus 100, an outline of a video game whose progress is controlled by the video game processing apparatus 100 will be described.

  In this example, the video game is a moving scene in which a user of the video game processing apparatus 100 (that is, a video game player) moves a character (user character, player character, or avatar) that is his / her own character in the virtual space. It is the composition which includes. In the video game in this example, it is assumed that the player character can arbitrarily move in a plurality of virtual acoustic spaces (for example, outdoors, indoors, caves, etc.). And the area | region (transition area | region) in which the predetermined | prescribed acoustic effect was set may be set to the boundary comprised by the some virtual acoustic space in this example.

  FIG. 2 is an explanatory diagram for explaining the transition region. As shown in FIG. 2, it is assumed that the transition region in this example has a shape constituted by a line segment connecting two points O1 and O2 and a semicircle having a radius R1 centering on the two points O1 and O2. . Note that the shape of the transition region may be any shape that can be easily set in the virtual acoustic space, and is not limited to a shape composed of a line segment (or straight line) and a semicircle. The shape of the transition region may be a three-dimensional shape, for example, a thick oval shape or a so-called capsule shape.

  Further, the acoustic effect set in the transition region is, for example, “the corresponding effect increases as the listening position LP approaches the line segments O1 and O2 (for example, the listening sound increases)”. It is preferable that the configuration be related to the distance to O1 and O2.

  FIG. 3 is an explanatory diagram for explaining the relationship between the virtual acoustic space and the transition region. Here, the transition region TR1 including the boundary between the virtual acoustic space S1 and the virtual acoustic space S2 and the transition region TR2 including the boundary between the virtual acoustic space S2 and the virtual acoustic space S3 will be described as examples. A plurality of black dots in FIG. 3 are examples of the listening position LP. In this example, the effect that affects the listening sound in the virtual acoustic space is indicated by a value (effect value), and the type of the effect value is a spatial effect value (a value indicating the effect in the virtual acoustic space) and a transition effect value (transition) The value will be described in the following manner. That is, in this example, the effect value, the spatial effect value, and the transition effect value are handled in the same unit. Note that the effect value, the space effect value, and the transition effect value do not necessarily have to be in the same unit, and may be in the same unit system capable of four arithmetic operations.

  At the listening position LP1, the listening sound is affected only by the setting of the virtual acoustic space S1. On the other hand, for example, when the listening position is located in the transition region TR1 in the virtual acoustic space S1 according to the user's operation, the listening sound is also affected by the setting of the transition region TR2. In this example, since an upper limit (maximum negative value) of the transition effect value and a lower limit (lower limit footing value) of the effect value are set in each transition region, as shown in FIG. That is, the value obtained by subtracting the transition effect value from the spatial effect value at the listening position does not fall below “0”, which is the lower limit footing value.

  When the listening position is located in the virtual acoustic space S2, the listening sound is affected by the setting of the virtual acoustic space S2. Specifically, at the listening position LP2, the listening sound is affected only by the setting of the virtual acoustic space S2. On the other hand, for example, when the listening position is located in the transition region TR1 or the transition region TR2 in the virtual acoustic space S2 according to the user's operation, the listening sound is also affected by the setting of the transition region to be located. The same applies when the listening position is located in the virtual acoustic space S3.

  In this example, the storage unit 12 includes an acoustic information storage unit 12a, an acoustic space information storage unit 12b, and a transition area information storage unit 12c in order to control the progress of the video game described above.

  The acoustic information storage unit 12a is a storage medium that stores acoustic information that is appropriately updated as the video game progresses. In this example, the acoustic information includes information for outputting the listening sound that is heard by the player character at the listening position, which is the position of the player character in the virtual space, by the plurality of sound output units 14. That is, it is information indicating how the sound generated by the sounding object (sound source object) existing in the virtual space can be heard at a position determined in advance as the listening position.

  FIG. 4 is an explanatory diagram illustrating an example of a storage state of acoustic information in the acoustic information storage unit 12a. As shown in FIG. 4, the acoustic information includes a character ID for uniquely identifying a character, an operation flag indicating a character (player character) that is a player's operation target, listening position coordinates indicating a listening position, and listening. When the position is located within the audible area of the sound source object, a sound source object ID indicating a sound source object corresponding to the audible area and a listening sound are included.

  Here, the operation flag is a flag for specifying a character that is an operation target of the player among a plurality of characters. In this example, the character with the operation flag set to “1” is “player character”, and the position of the player character is the listening position.

  The listening sound is information indicating a sound heard by the player character at the listening position that is the position where the player character is present in the virtual space. In this example, an example in which a listening sound corresponding to a 5.1ch surround environment is registered will be described.

  Although not shown, the acoustic information storage unit 12a includes 5.1ch such as the position of the player in the real space and the output direction of each speaker (in this example, the direction from the placement position of each speaker toward the player's position). It is assumed that information necessary for realizing the surround environment is stored. Such information is not fixed and may be changed by the user, for example.

  The acoustic space information storage unit 12b is a storage medium that stores acoustic space information that is information related to sound that can be generated in the virtual acoustic space. In this example, the acoustic space information includes information for determining a sound corresponding to the listening position.

  FIG. 5 is an explanatory diagram illustrating an example of the storage state of the acoustic space information in the acoustic space information storage unit 12b. As illustrated in FIG. 5, the acoustic space information includes a virtual acoustic space number for uniquely identifying the virtual acoustic space, sound (sound data), and a spatial effect.

  Here, the space effect means an effect given to sound in the virtual acoustic space. As effects, various effects such as reverb (reverberation) and filters (low bass filter and high bass filter) can be considered. That is, the sound generated in the virtual acoustic space becomes a listening sound in a state where an effect corresponding to the content of the space effect is applied (for example, a state in which the sound quality is changed). In this example, the information indicating the spatial effect includes a spatial effect value and various values obtained by quantifying the degree of the spatial effect (for example, values obtained by quantifying the reverberation rate, the attenuation rate, etc.).

  Here, the spatial effect value is a value for unified management of various values obtained by quantifying the degree of the spatial effect. In this example, as described with reference to FIG. 3, a value obtained by subtracting the transition effect value from the spatial effect value is used as the effect value. And in order to specify the various values corresponding to the effect value when specifying the listening sound, the spatial effect value (in other words, the basic value of the effect value) and other various values are associated with each other in the acoustic space information. Yes. Although not shown, the acoustic space information includes a change rule (for example, rate of change) of another value according to the change of the space effect value.

  The transition area information storage unit 12c is a storage medium that stores transition area information that is information regarding a transition area including part or all of a boundary constituted by at least two virtual acoustic spaces. In this example, the information between transition areas includes information regarding effects (transition effects) that affect sound in the transition areas.

  FIG. 6 is an explanatory diagram illustrating an example of a storage state of transition region information in the transition region information storage unit 12c. As shown in FIG. 6, the transition area information includes a virtual acoustic space number for uniquely specifying a plurality of virtual acoustic spaces that constitute the boundary, the position and shape of the transition area, and the transition effect.

  Here, as described with reference to FIG. 3, the transition region is a region including a part or all of a boundary constituted by at least two virtual acoustic spaces. Therefore, a configuration in which one transition region belongs to three or more virtual acoustic spaces may be adopted.

  The position of the transition area is defined by coordinates (representative coordinates) indicating the position of the transition area in the virtual acoustic space. In addition, the shape of the transition region is defined by an expression indicating a line segment and an expression indicating a semicircle.

  The transition effect means an effect given to sound in the transition region. As effects, various effects such as reverb and filters can be considered as well as the space effect. In this example, the information indicating the transition effect includes a transition effect value calculation rule, a lower limit footing value, and an interpolation value.

  Here, the transition effect value is a value obtained by quantifying the degree of the transition effect. In this example, the transition effect value in the transition region is calculated according to the transition effect value calculation rule. Although the calculation rule is not particularly limited, for example, a rule in which the transition effect value increases as the listening position approaches the center of the transition region, such as a rule that increases in proportion to the distance from the listening position to the line segment, is preferable. . That is, it is preferable that the transition region is configured to reduce the spatial effect value as the listening position approaches the line segment. By adopting such a configuration, it is possible to make a natural change in sound when transitioning between a plurality of virtual acoustic spaces with different settings. In this case, the vicinity of the center of the transition region (for example, a line segment defining the transition region) may be set so as to cross the boundaries of the plurality of virtual acoustic spaces, or may be set on the same boundary. .

  The lower limit footing value means the lower limit value of the effect value. That is, it is a value set to prevent the effect value as a subtraction result obtained by subtracting the transition effect value from the spatial effect value from being a value contrary to the intention of the person who sets the transition region. The information indicating the transition effect may be configured to include the upper limit value.

  The interpolated value is a value for interpolating changes at feature points in the transition area (for example, points on the line segment or points on the outer edge of the area). In this example, it is assumed that a value on the line segment defining the transition area (maximum minus value) and a value on the outer edge of the transition area (for example, minus 0) are set as interpolation values.

  Next, the operation of the video game processing apparatus 100 of this example will be described. Note that the contents of operations and processes not related to the present invention may be omitted.

  FIG. 7 is a flowchart illustrating an example of the listening sound related process executed by the video game processing apparatus 100. In the listening sound related processing, processing related to the listening sound specified according to the listening position is performed.

  The listening sound related processing is started when, for example, the control unit 11 determines that the listening position has moved to the virtual acoustic space in accordance with the progress of the video game.

  In the listening sound related processing, first, the control unit 11 specifies the listening position (step S101). In this example, the control unit 11 specifies the current position of the player character that moves according to the user's operation as the listening position.

  When the listening position is specified, the control unit 11 specifies the virtual acoustic space to which the specified listening position belongs (step S102). In this example, the control unit 11 searches the virtual acoustic space including the coordinates indicating the listening position, thereby specifying the virtual acoustic space to which the listening position belongs (that is, the listening position is located).

  When the virtual acoustic space is specified, the control unit 11 determines whether or not the listening position is located in the transition area (step S103). In this example, the control unit 11 searches the transition area information based on the identified virtual acoustic space, and determines whether the listening position is located in the transition area based on the transition area information included in the search result. . Specifically, the control unit 11 determines whether or not the listening position is located in the transition area by comparing the coordinates of the transition area indicated by the transition area information with the coordinates indicating the listening position. Here, for example, when it is determined that the listening position is not located in the transition area because the coordinates indicating the listening position do not coincide with the coordinates indicating the transition area (N in step S103), the control unit 11 performs step S108 described later. Move on to processing.

  On the other hand, for example, when the coordinates indicating the listening position coincide with the coordinates indicating the transition area, and it is determined that the listening position is located in the transition area (Y in step S103), the control unit 11 refers to the transition area information. Then, the transition effect value is calculated (step S104). In this example, the control unit 11 calculates a transition effect value corresponding to the listening position based on a transition effect value calculation rule.

  When the transition effect value is calculated, the control unit 11 sets a value obtained by subtracting the calculated transition effect value from the spatial effect value of the virtual acoustic space to which the listening position belongs (that is, the effect value as a subtraction result) in the transition region. It is determined whether or not the lower limit foot limit value is exceeded (step S105).

  If it is determined that the effect value as the subtraction result is lower than the lower limit foot limit value (Y in step S105), the control unit 11 specifies the lower limit foot foot value set in the transition region as the effect value (step S106). ). On the other hand, when determining that the effect value as the subtraction result does not fall below the lower limit foot limit value (N in Step S105), the control unit 11 specifies the subtraction result as the effect value (Step S107). When the listening position is not located in the transition area, the control unit 11 specifies the spatial effect value as the effect value.

  When the effect value is specified, the control unit 11 specifies the listening sound based on the specified effect value (step S108), and ends the process here. In this example, the control unit 11 specifies the listening sound based on the specified effect value and the acoustic space information corresponding to the virtual acoustic space where the listening position is located.

  As described above, in the above-described embodiment, the video game processing device 100 that outputs the listening sound in the virtual acoustic space in which the spatial effect that affects the sound is set is configured by at least two virtual acoustic spaces. It is determined whether or not the listening position is located in the transition region based on the transition region information in which the transition region including a part or all of the boundary is associated with the transition effect that affects the spatial effect (for example, Step S103) When the listening position is located in the transition area, the listening sound is specified based on the transition effect corresponding to the transition area (for example, Step S108), so that the listening according to the change in the listening position. The change of sound can be made natural.

  That is, by setting a transition area in the virtual acoustic space, it is possible to provide the user with a natural effect change (that is, a sound effect transition) based on the position of the player character or the like when transitioning between different acoustic spaces.

  In the above-described embodiment, the video game processing apparatus 100 stores the acoustic space information in which the sound that can be generated in each virtual acoustic space and the spatial effect that affects the generation of the sound are associated with each other. The information storage unit 12b is provided, and the listening sound is specified based on the acoustic space information corresponding to the virtual acoustic space where the listening position (for example, the position of the player character) is located and the transition effect (for example, steps S103 to S108). Therefore, it becomes possible to design a video game by a procedure of setting a transition effect after generating a virtual acoustic space, so that the design burden can be reduced.

  Further, in the above-described embodiment, the acoustic space information includes a spatial effect value in which the content of the spatial effect such as the reverberation rate and the attenuation rate is quantified, and the transition region information is quantified in the content of the transition effect. Including the transition effect value calculation rule, the video game processing device 100 is configured to identify the listening sound based on the spatial effect value and the transition effect value calculated according to the calculation rule (for example, steps S104 to S108). Therefore, more natural sound effect transitions can be realized by adjusting numerical values when designing a video game.

  In the embodiment described above, the spatial effect value and the transition effect value are in the same unit system, and the transition area information includes the lower limit footage value when the transition effect value is subtracted from the spatial effect value, When the game processing apparatus 100 subtracts the transition effect value from the space effect value (for example, step S105) and the subtraction result satisfies a predetermined update condition with respect to the lower limit foot limit value (for example, the subtraction result is the lower limit footstep). When the value is below the value, the subtraction result is updated to the same value as the lower limit footstep value (for example, step S106), and the listening sound is specified based on the updated subtraction result (for example, step S108). Therefore, it is possible to prevent the listening sound from being in a state contrary to the intention of the creator (or setter) of the transition region. In addition, by combining the idea of the effect subtraction area (transition area in this example) and the lower limit footing function into the video game processing device, it is no longer necessary to consider the “excess area” that is a side effect of simple shape, It is possible to greatly reduce labor (for example, labor required by a setter when setting a transition area) and the amount of data. In addition, it is not necessary to set a multi-stage transition region, and a linear and more natural effect change can be given to the user.

  In the above-described embodiment, the transition area is an area defined by a line segment connecting at least two coordinates in the virtual space and the radii of two semicircles each centered on the at least two coordinates. Since a certain configuration is used, the use of a very simple shape such as a line segment and a radius greatly reduces the labor of input when handling the transition region.

  It should be noted that at the time of transition between different acoustic spaces, a change (fade) with time after the change point has been performed in the simplest method. As an improved version of this prior art, a current position detection version in which the space region is finely divided can be considered. However, there is a problem that it is necessary to set spatial information finely and in large quantities, and the effort of numerical input and area setting becomes enormous. Further, as other improved versions, a sphere (or a cylinder) or a box-type transition region can be considered. However, there is a problem that the cases that can be used are limited without matching to an actual complicated shape. In contrast to such an improved version, the above-described configuration using a transition region having a simple shape makes it possible to achieve acoustic effect transition in a manner that reduces the input load and the like compared to the improved version described above. .

  In the embodiment described above, the transition region is a substantially oval region defined by a line segment connecting two points on the same plane in the virtual space and a distance on the same plane from the line segment. Since it has a certain configuration (see, for example, FIGS. 2 and 3), the setting of the transition region is simplified. That is, since the boundary of the virtual acoustic space is often a straight line (for example, a door opening or the like), it can be said that the shape is suitable for an actual use application.

  Although not specifically mentioned in the above-described embodiment, when the listening position is located on a line segment, the video game processing apparatus 100 determines that the transition effect is the maximum, identifies the listening sound, and listens. When the position is located on the outer edge of the transition region, the listening sound may be specified by regarding the transition effect as being minimal. In this case, the video processing apparatus 100 may be configured to use transition region information including an interpolation value (for example, a maximum minus value). With such a configuration, it is possible to specify the listening sound in the transition region more quickly.

  Although not particularly mentioned in the above-described embodiment, the line segment constituting (or defining) the transition area has a position in the virtual space according to the progress of the video game, such as a door arranged in the virtual space. The video game processing apparatus 100 may be associated with an object that can be changed, and the transition area corresponding to the object may be moved or deformed in accordance with the movement or deformation of the object. With such a configuration, it is possible to specify the listening sound according to the change of the object in the virtual space (particularly, the virtual acoustic space).

  Although not particularly mentioned in the above-described embodiment, the video game processing apparatus 100 responds to the progress of the video game (for example, when a predetermined operation by the user is received or when a predetermined time has elapsed in the virtual space. As a configuration for changing the transition effect of the transition region set in the virtual acoustic space (for example, changing the setting of the filter according to the weather change in the virtual acoustic space) Good.

  Although not particularly mentioned in the above-described embodiment, the video game processing device may be configured to set a transition area in the virtual acoustic space in accordance with a user operation.

  Although not particularly mentioned in the above-described embodiment, the transition area information may include sound. In this case, for example, the video game processing apparatus 100 determines which of the sounds included in the acoustic space information and the sounds included in the transition area information is to be preferentially output based on the priorities set in advance for each sound. The listening sound may be specified according to the determination result (for example, the sound in which the spatial effect and the transition effect are reflected in the priority sound is specified as the listening sound). The video game processing apparatus 100 may be configured to add and synthesize the sound included in the acoustic space information and the sound included in the transition area information and output the result. With such a configuration, it is possible to easily change the listening sound output at the time of transition of the virtual acoustic space.

  In the above-described embodiment, the video game processing apparatus 100 is configured to execute various processes such as the above-described game process based on the game program read from the game cartridge 20, but from the game server to the communication network such as the Internet. You may make it acquire a game program via.

  Further, the video game processing apparatus 100 may function as a game server and provide a game program to the game terminal via a communication network. In other words, the video game processing apparatus 100 may be configured to function as a server when realizing so-called cloud gaming.

  In the embodiment described above, the video game processing apparatus 100 executes the various processes described above according to various control programs (for example, a video game processing program) stored in a storage device included in the video game processing apparatus 100.

  INDUSTRIAL APPLICABILITY According to the present invention, it is useful for making the change in the listening sound natural according to the change in the listening position.
