[Embodiment]
A game based on this game program is played in a virtual space (three-dimensional). The game based on this game program is a fighting action game in which a player character fights against other player characters or non-player characters in the virtual space. More specifically, the game of this embodiment is a so-called fighting game.

In this fighting game, the user (player) selects and controls one character (player character). The user controls the player character and can challenge other characters (e.g., non-player characters) to a battle in the virtual space. In a battle, the winner is decided when the vitality value of one of the characters reaches 0, for example.

Configuration of the Game Device
Hardware Configuration
1 is a block diagram showing the configuration of a game device 5. The game device 5 executes a predetermined game based on a user's operation. The game device 5 has a display 61 (display device), a speaker 62, and a controller 63 either externally connected or built-in.

The game device 5 may be a commercially available device such as a personal computer, PlayStation (registered trademark), XBox (registered trademark), PlayStation Vita (registered trademark), or Nintendo Switch (registered trademark).

In the game device 5, the game progresses based on the installed game program and game data. Game devices 5 can communicate data with each other using a communication network (not shown) or a short-range wireless communication device (not shown).

The game device 5 has a network interface 51, a graphics processing unit 52, an audio processing unit 53, an operation unit 54, a memory unit 55, and a control unit 56. The network interface 51, the graphics processing unit 52, the audio processing unit 53, the operation unit 54, and the memory unit 55 are electrically connected to the control unit 56 via a bus 59.

The network interface 51 is communicatively connected to the communication network to transmit and receive various data, for example, between other game devices 5 and external server devices (not shown).

The graphics processing unit 52 renders game images including the player character and various objects in a virtual space (hereinafter, virtual space VS) in a moving image format according to game image information output from the control unit 56. The graphics processing unit 52 is connected to a display 61 (e.g., a liquid crystal display). The game images rendered in a moving image format are displayed on the display 61 as a game screen.

The graphics processing unit 52 displays a predetermined range within the virtual space VS on the display 61. The graphics processing unit 52 determines the display range according to instructions from the control unit 56.

The audio processing unit 53 is connected to the speaker 62. The audio processing unit 53 plays digital game audio according to instructions from the control unit 56. Specifically, the audio processing unit 53 converts the audio data output by the control unit 56 into an analog signal and outputs it to the speaker 62.

The operation unit 54 is connected to the controller 63. The operation unit 54 transmits and receives signals to and from the controller 63. The game player inputs signals (commands, data, etc.) to the game device 5 by operating various controls such as buttons on the controller 63.

The storage unit 55 is composed of a HDD, SSD, RAM, ROM, etc. The storage unit 55 stores game data, various programs including game programs, etc. Examples of game data include game media and user account information.

The control unit 56 controls the operation of the game device 5. The control unit 56 includes a CPU (microcomputer) and a semiconductor memory. The semiconductor memory stores programs and data for operating the CPU.

<Functional configuration of the control unit 56>
The control unit 56 executes a game program, thereby functioning as a game progression unit 561, a position setting unit 562, and a display unit 563 (see FIG. 1).

(Game Progression Unit 561)
The game progression unit 561 progresses the game by controlling the actions of player characters, non-player characters, and predetermined objects within the virtual space VS.

The game progression unit 561 uses, for example, AI (artificial intelligence) to control the movements of non-player characters. The game progression unit 561 controls the movements of player characters in response to instructions from the user (player). The user's instructions are input to the operation unit 54 by the controller 63. The operation unit 54 sends the input (user's instructions) from the controller 63 to the game progression unit 561.

For example, the user can instruct the game progression unit 561 to move the player character by operating the controller 63. The user can instruct the game progression unit 561 to challenge another character to a battle by having the player character perform a specified action. Examples of the battle challenge action include the player character talking to the opponent character, or attacking the opponent character.

In the following, one of the characters in the battle will be referred to as the first character C1, and the opponent as the second character C2. The first character C1 is a player character controlled by the user. The second character C2 may be a non-player character or a character controlled by another user.

During a match, the user can instruct the game progression unit 561 on the actions of the first character C1, such as punch attacks and kick attacks, by operating the controller 63.

Even during a match, the user can instruct the first character C1 to move (backward, forward, etc.) by operating the controller 63. During a match, the game progression unit 561 limits the range in which the first character C1 and the second character C2 can move to within a first area BA1, which will be described later. During a match, the game progression unit 561 limits the direction of movement of the first character C1 and the second character C2 to only directions along (parallel to) the virtual surface S1 (described later).

(Position setting section 562)
The position setting unit 562 reserves a battle location within the virtual space, and places the first character C1 and the second character C2 in the battle location.

A battle requires a three-dimensional area of a certain size (hereafter referred to as the battle area BA). The position setting unit 562 secures the battle area BA when it is decided to start the battle. Figure 2 shows the battle area BA.

The battle area BA is a cube with width W, depth D, and height H (see Figure 2). The battle area BA is composed of a first area BA1 and a second area BA2. Both the first area BA1 and the second area BA2 are cubes.

The first area BA1 is the area where the first character C1 and the second character C2 compete during a battle. The first area BA1 is a cubic area with a width W, a depth D1, and a height H.

The first area BA1 is secured based on the character placement straight line BL. Specifically, the first area BA1 is defined so that the center line of the longitudinal direction of its bottom surface (rectangle) coincides with the character placement straight line BL. Two characters are placed on the character placement straight line BL when the battle begins.

The second area BA2 is an area in which a virtual camera VC (described later) is placed. The second area BA2 is adjacent to the first area BA1 (see FIG. 2). The second area BA2 is an area with a width W, a depth D2, and a height H, where D = D1 + D2.

In this game program, meters (m) are used as the unit of distance in the virtual space VS. In this game program, the size of objects (e.g. characters, buildings, trees, etc.) in the virtual space VS is determined by corresponding a distance of 1.0 in the coordinate system of the virtual space VS to 1.0 meter in the real world. In this game program, the battle area BA has a width W = 7 m, a depth D = 12 m, and a height H = 5 m. Also, D1 = 3 m, and D2 = 9 m.

In addition to characters, various objects are placed in the virtual space VS. Examples of objects other than characters include buildings, trees, benches, etc.

Some of these objects can get in the way of a battle. "Getting in the way of a battle" means, for example, interfering with (colliding with) a character during a battle and impeding the character's movements. Also, some objects can get in the way of taking pictures with the virtual camera VC (described below) (blocking the shooting range of the virtual camera VC).

In the following, objects that get in the way of battles or photography are called obstruction objects. Obstruction objects are set with parameters that indicate that they are obstruction objects (hereafter, obstruction parameters). For example, building objects are set with obstruction parameters.

The battle area BA must be set so that it does not contain any obstruction objects. The position setting unit 562 has the function of searching for obstruction objects within the candidate areas of the battle area BA.

The position setting unit 562 performs a ray cast to search for obstructing objects. The position setting unit 562 performs a more detailed ray cast on the candidate area of the first area BA1 than on the candidate area of the second area BA2.

When it is decided that a battle will begin, the position setting unit 562 selects a candidate for the character placement line BL. Specifically, the position setting unit 562 tries steps 1 to 4 (each of which is described below) in this order to select the character placement line BL. The position setting unit 562 reserves the battle area BA based on the character placement line BL candidate selected in the first successful step. The position setting unit 562 places the first character C1 and the second character C2 on the selected character placement line BL.

-Step 1-
In this procedure, the position setting unit 562 checks whether a pre-specified designated line can be selected as the character arrangement line BL. The designated line is a line set in the virtual space VS. The position of the designated line is determined so that the battle area BA can be secured when the designated line is used as the character arrangement line BL.

The designated straight line is associated with a specific area (hereinafter referred to as the designated area SA) in the virtual space VS. The designated straight line is associated in advance by the developer of the game program when developing the game program. The designated straight line is prepared as game data.

In this game program, the designated straight line is positioned so that a specific object (such as a famous building object) becomes the background during the match. In this way, the designated straight line can be used to enhance the game's presentation.

In this procedure, the position setting unit 562 determines whether the reference point defined for the first character C1 is within the designated area SA. The method for determining the reference point is arbitrary. For example, the reference point can be set to one of the feet of the first character C1.

If the reference point is present within any of the designated areas SA, the position setting unit 562 selects the designated line corresponding to that designated area SA as a candidate for the character placement line BL (first candidate selection). If the reference point is not present within any of the designated areas SA, the selection of the character placement line BL using this procedure fails.

-Step 2-
In this procedure, the position setting unit 562 checks whether or not a straight line connecting the two fighting characters (hereinafter referred to as the reference line) can be selected as a candidate for the character arrangement line BL.

The position setting unit 562 determines a reference line based on the positions of the two characters at the time when it is decided to start the battle. If the battle area BA can be secured using the reference line as the character positioning line BL, the position setting unit 562 selects the reference line as a candidate for the character positioning line BL (selection of the second candidate).

Specifically, the position setting unit 562 assumes that the reference line is the character arrangement line BL and determines a provisional first area BA1. Furthermore, the position setting unit 562 provisionally determines a second area BA2 adjacent to the first area BA1. In other words, the position setting unit 562 determines a provisional battle area BA using the reference line.

The position setting unit 562 performs an obstruction object search in the provisionally determined battle area BA. If no obstruction object is found by the obstruction object search, the position setting unit 562 determines that the battle area BA can be secured by using the reference line as the character placement line BL. If an obstruction object is found by the obstruction object search, the selection of the character placement line BL using this procedure has failed.

--Step 3--
In this procedure, the position setting unit 562 determines a plurality of provisional lines that are provisional character arrangement lines BL, and checks whether or not it is possible to select one candidate character arrangement line BL from among the provisional lines. Specifically, the position setting unit 562 checks for each provisional line whether or not it is possible to secure a battle area BA using the provisional line as the character arrangement line BL.

There is no limitation on how the provisional lines are created. In this example, the position setting unit 562 rotates the reference line to create multiple provisional lines. The center of rotation of the reference line is the midpoint between the first character C1 and the second character C2. The axis of rotation is oriented vertically in the virtual space VS.

In this game program, the position setting unit 562 creates seven provisional lines. The seven provisional lines form angles of -60°, -45°, -30°, 30°, 45°, 60°, and 90° with respect to the reference line, respectively.

In this procedure, the position setting unit 562 also searches for obstruction objects in the provisionally determined battle area BA for each provisional line. If obstruction objects are found in all of the provisionally determined battle areas BA, the selection of the character placement line BL using this procedure is unsuccessful.

Assume that the obstruction object search results in finding one or more provisional lines that are candidates for the character placement line BL. In this case, the position setting unit 562 selects one of the one or more candidates as the character placement line BL candidate (third candidate selection).

The developer may determine as desired the method for selecting one of the multiple character placement straight line BL candidates. For example, the position setting unit 562 selects, from among the multiple candidates, the one that can maximize the distance between the first character C1 and the second character C2 (the one that can maximize the section where no obstructing objects exist) as one character placement straight line BL candidate.

--Step 4--
In step 4, the position setting unit 562 checks whether a straight line previously set by the developer of the game program (a pre-set straight line, described later) can be selected as the character positioning straight line BL. Step 4 is similar to step 1 in that a straight line that is a candidate for the character positioning straight line BL is set in the virtual space VS by the developer in advance. However, step 4 differs from step 1 in the position where the straight line set by the developer (pre-set straight line) is placed.

In the virtual space VS, the ground is divided into multiple small areas (two-dimensional areas). All areas in which a character can move are divided into small areas. In this example, the small areas are 1m x 1m.

Each small area is assigned a line (hereafter referred to as a pre-set line) that can be used as a character placement line BL to secure a battle area BA. The small areas and pre-set lines are prepared in advance as game data by the developer when developing the game program.

When developing the game program, the developer of this game program performs raycasting in advance for each small area to determine the character placement line BL that will ensure the battle area BA. The calculation results are included in the game data, for example, in the form of a table (hereafter referred to as a line search table). The line search table is configured so that it can be searched using position information in the virtual space VS.

In step 4, the position setting unit 562 searches the line search table using information on the reference point (e.g., position information on the reference point) defined for the first character C1. Since all areas in which the characters can move are divided into small areas, in step 4, one or more character arrangement line BL candidates are always found near the first character C1. The position setting unit 562 selects one character arrangement line BL candidate from the one or more character arrangement line BL candidates (selection of the fourth candidate).

The developer may determine as desired how to select one of the multiple character placement straight line BL candidates. For example, the position setting unit 562 selects one character placement straight line BL candidate that can maximize the distance between the first character C1 and the second character C2 (maximize the section where no obstructing objects exist).

(Display unit 563)
The display unit 563 cuts out a predetermined range in the virtual space VS as a display range and generates game images (moving images). The display unit 563 controls the graphics processing unit 52 to display the generated moving images on the display 61 (display device).

To generate moving images, the display unit 563 sets up a virtual camera (hereinafter referred to as virtual camera VC) in the virtual space VS. The display unit 563 generates 3D images (moving images) by capturing images of the virtual space VS with the virtual camera VC. Hereinafter, "generation of moving images" by the display unit 563 may be referred to as "capturing images with the virtual camera VC."

The display unit 563 can set the installation position, shooting direction (hereinafter, shooting direction SD), angle of view, etc. for the virtual camera VC. The display unit 563 determines the range of the virtual space VS to be cut out as the display range according to the settings of the virtual camera VC, such as the position, shooting direction, and angle of view of the virtual camera VC.

The display unit 563 sends the generated moving image to the graphics processing unit 52. The graphics processing unit 52 displays the moving image sent from the display unit 563 on the display 61.

The display unit 563 moves the installation position and shooting direction SD of the virtual camera VC according to the game situation. For example, when the player character (first character C1) is moving on foot within the virtual space VS, the virtual camera VC moves behind the first character C1, following the first character C1.

During a match, the virtual camera VC is placed within the second area BA2. During a match, the virtual camera VC takes pictures facing the direction of a virtual surface S1 (see Figure 2) defined within the first area BA1. The virtual surface S1 is a virtual plane that includes the character placement straight line BL and extends vertically in the virtual space VS. The virtual surface S1 is a rectangle with a width W and a height H, and is entirely contained within the first area BA1.

The virtual camera VC may move in a first movement mode M1 and a second movement mode M2, described below, under the control of the display unit 563.

The first movement mode M1 is executed when it is decided to start a match. In the first movement mode M1, the virtual camera VC moves from its current position to a position within the second area BA2 where it can capture the entire virtual surface S1.

In the first movement mode M1, the virtual camera VC changes the shooting direction so that the shooting direction SD (see FIG. 2) is perpendicular to the virtual surface S1 when the first movement mode M1 is completed. The virtual camera VC continues to shoot the first character C1 and the second character C2 even while moving in the first movement mode M1.

The second movement mode M2 is implemented during a match. In the second movement mode M2, the virtual camera VC moves only in a direction parallel to the virtual surface S1 while photographing the first character C1 and the second character C2.

Example of operation
When the game is started, the game progression unit 561 moves the player character (first character C1) within the virtual space VS in response to the user's (game player's) operation of the controller 63. The game progression unit 561 also moves objects such as non-player characters in the virtual space VS as necessary.

The display unit 563 displays the movements of the first character C1 and other non-player characters on the display 61. The position of the virtual camera VC at this time is behind the first character C1. The virtual camera VC moves in accordance with the movement of the first character C1.

As the game progresses, the user operates the controller 63 to cause the first character C1 to challenge a battle. The virtual camera VC captures the challenge.

When requesting a match, in addition to the first character C1, the opponent's character (second character C2) is also photographed by the virtual camera VC. At this time, the moving image displayed on the display 61 is recognized by the user as three-dimensional.

When the position setting unit 562 decides to start a battle, it attempts steps 1 to 4 of selecting the character placement line BL in this order. For example, if the position setting unit 562 succeeds in selecting the character placement line BL in any of steps 1, 3, or 4, it will be necessary to move the first character C1, the second character C2, and the virtual camera VC. If the position setting unit 562 succeeds in selecting the character placement line BL in step 2, it will be necessary to move only the virtual camera VC.

When the match starts, the display unit 563 moves the virtual camera VC. The movement of the virtual camera VC at the start of the match is in the first movement mode M1.

When a battle begins, it may be necessary to move the first character C1 and the second character C2. When it is necessary to move the first character C1 and the second character C2, the position setting unit 562 moves the first character C1 and the second character C2 in parallel with the movement of the virtual camera VC in the first movement mode M1. Specifically, the position setting unit 562 places the first character C1 and the second character C2 within the first area BA1 and on the character placement straight line BL.

The virtual camera VC captures the two characters who will be fighting even while they are moving in the first movement mode M1. Therefore, this game program generates seamless video images from the time the challenge to the match is made to the completion of the first movement mode M1.

Figure 3 shows one frame of a moving image at the completion of the first movement mode M1. At the completion of the first movement mode M1, the first character C1 and the second character C2 are positioned on the character positioning line BL.

As shown in FIG. 3, multiple buildings BLD are displayed in the background. The buildings BLD are an example of an object. If the character placement line BL is the first candidate selection, a background that matches the developer's intentions (such as a famous building object) is displayed.

In FIG. 3, the building BLD has an obstruction parameter set. In FIG. 3, the building BLD is outside the battle area BA. Therefore, the building BLD does not interfere with the battle.

When the first movement mode M1 is completed, the shooting direction SD of the virtual camera VC is perpendicular to the virtual plane S1. Therefore, when the first movement mode M1 is completed, even though the virtual camera VC is shooting a three-dimensional space, the video images captured by the virtual camera VC appear to be two-dimensional images.

The movement of the virtual camera VC during the match is in the second movement mode M2. In the second movement mode M2, the virtual camera VC moves only in a direction parallel to the virtual surface S1 while capturing images of the first character C1 and the second character C2 via the display unit 563. During the match, the game progression unit 561 restricts the movement direction of the first character C1 and the second character C2 to a direction along the virtual surface S1. Therefore, the moving images during the match appear to be two-dimensional moving images.

In summary, this aspect is a game program that causes a computer to function as a game progression unit 561 that pits a first character against a second character in a three-dimensional virtual space, a virtual camera VC that captures moving images of a predetermined range in the virtual space, and a display unit 563 that displays the moving images on a display device, the virtual camera VC is movable within the virtual space, has a first movement mode M1 that moves so as to face an imaginary plane that includes a straight line connecting the first character and the second character, and the virtual camera moves in the first movement mode M1 when the battle begins.

Effects of this embodiment
In this embodiment, when the first movement mode M1 is completed, the moving images captured by the virtual camera VC appear as two-dimensional images, even though the virtual camera VC is capturing images of a three-dimensional space. According to this embodiment, it is possible to diversify the effects of images in a game played in a virtual space.

[Other embodiments]
The position and shooting direction of the virtual camera VC are merely examples. For example, the shooting direction SD during a match does not have to be perpendicular to the virtual plane S1.

The virtual camera VC may capture images of the characters from directly above during a match.

The game program may be implemented as a game program for a so-called online game. When the game program is for an online game, the processing that was performed by the game device 5 may be performed on the server side instead, or may be shared between the server side and the client (game device 5) side.

Instead of being positioned behind the character, the virtual camera VC may be set to the position of the character's viewpoint (head). In other words, the game program may function as a so-called first person view game.

A mode may be provided in which the position and direction of the virtual camera VC can be changed in response to user operation. It is desirable to restrict user operation of the virtual camera VC while the first movement mode M1 or the second movement mode M2 is being executed.

The game program may be implemented to decide to start a battle if the player character is attacked by another character during a non-battle situation.

When moving the virtual camera VC in the first movement mode M1, the screen may be darkened or a predetermined animation or image (such as one indicating the start of a battle) may be displayed. This allows the user to play without being aware of the unnaturalness of the virtual camera VC and character movement at the start of a battle.

The method of determining the center of rotation in step 3 is merely an example. The center of rotation may be set based on the position of either character C1 or C2. The provisional line in step 3 may be, for example, a line obtained by translating the reference line in either direction. The provisional line in step 3 may be created, for example, by connecting a point near either character C1 or C2 to another point selected at random.

There are no limitations on the shape of the three-dimensional area (battle area BA) as long as it can be secured based on the character placement line BL. The three-dimensional area can be, for example, a sphere, hemisphere, etc.

After the match ends, the positions of characters C1 and C2 may remain as they were at the end of the match, or may return to their positions before the match.

Three or more characters may be placed in the three-dimensional area at the start of the battle. A third character may be placed in the three-dimensional area during the battle.

Even when these other embodiments are adopted, the effects of the present embodiment are exhibited. In addition, this embodiment can be combined with other embodiments, and other embodiments can be combined with each other as appropriate.
