An operation signal representing the scan result is sent to the control unit 14 via the bus 12. The control unit 14 determines the user's game operation based on the operation signal.

[1-2. Game executed on game device]
By executing the game program read from the optical disc 36, the game apparatus 10 executes, for example, a competition game in which a character moves a moving object in a competition area of the game space. Hereinafter, a case where a soccer game in which a plurality of player characters move a ball on a field in a game space simulating a soccer game venue will be described.

  In this soccer game, a team operated by a user (hereinafter referred to as “user team”) and a team operated by an opponent (computer or other user) (hereinafter referred to as “opponent team”). A soccer game is held between. When the soccer game is started, for example, a game space is constructed in the main memory 16.

  FIG. 2 is a diagram illustrating an example of the game space. A game space 50 shown in FIG. 2 is a virtual three-dimensional space in which three coordinate axes (Xw axis, Yw axis, and Zw axis) orthogonal to each other are set. As shown in FIG. 2, a field 52 that is an object representing a soccer field is arranged in the game space 50.

  On the field 52, two goal lines 54a and 54b, two touch lines 56a and 56b, and a center line 58 are represented. The pitch 59 surrounded by the two goal lines 54a and 54b and the two touch lines 56a and 56b and the periphery of the pitch 59 (a predetermined area outside the pitch 59 in contact with the goal lines 54a and 54b or the touch lines 56a and 56b). In the match.

  On the field 52, a goal 60 which is an object representing a soccer goal, a player character 62 which is an object representing a soccer player belonging to the user team, and a player character which is an object representing a soccer player belonging to the opponent team. 64 and a ball 66 that is an object representing a soccer ball (moving object) are arranged.

  The ball 66 moves on the field 52. When the ball 66 is in the pitch 59, the game is in an in-play state, and when the ball 66 is out of the pitch 59, the game is temporarily out-of-play. That is, the ball 66 moves on the pitch 59 while the game is in progress (in-play).

  Note that the position of each object is specified by, for example, three-dimensional coordinates in the world coordinate system (Xw-Yw-Zw coordinate system). Although omitted in FIG. 2, eleven player characters 62 belonging to the user team and eleven player characters 64 belonging to the opponent team are arranged on the field 52.

  When the player character 62 (64) approaches the ball 66, the player character 62 (64) and the ball 66 are associated under a predetermined condition. In this case, the movement action of the player character 62 (64) is a dribbling action. Hereinafter, the state in which the ball 66 is associated with the player character 62 (64) is described as “the player character 62 (64) holds the ball 66”.

  A virtual camera 68 (viewpoint) is set in the game space 50. A game screen representing a state in which the game space 50 is viewed from the virtual camera 68 is displayed on the display unit 32. The game screen is generated by converting the vertex coordinates of each object arranged in the game space 50 from the world coordinate system to the screen coordinate system using a predetermined coordinate conversion calculation.

  FIG. 3 is a diagram illustrating an example of a game screen displayed on the display unit 32. The game screen 70 shown in FIG. 3 includes three player characters 62a, 62b, 62c belonging to the user team, three player characters 64a, 64b, 64c belonging to the opponent team, and a ball 66. included. In the state of FIG. 3, the player character 62 a is performing a dribbling action in the vicinity of the center line 58.

  In addition, since the area | region in the visual field of the virtual camera 68 among the game spaces 50 is displayed on the game screen 70, in this embodiment, as shown in FIG. A part of the pitch 59 is displayed. For example, an area of the pitch 59 that is determined based on the position of the user's operation target is displayed on the game screen 70.

  For example, any of the player characters 62 belonging to the user team behaves based on the user's operation. In the state shown in FIG. 3, for example, a player character 62a (ball holder) holding the ball 66 is set as a user's operation target. A cursor 72 indicating that the player character 62a is set as an operation target of the user is displayed above the player character 62a.

  For example, the user operates the player character 62 a that is the operation target by inputting a given operation signal using the controller 30. For example, when the player character 62 a holds the ball 66, the user uses the controller 30 to cause the player character 62 a to perform a dribbling action or to cause the player character 62 a holding the ball 66 to perform a pass action.

  Among the player characters 62 (64) arranged in the game space 50, those that are not subject to the user's operation act autonomously according to a predetermined behavior algorithm. For example, player characters 62 (for example, player characters 62b and 62c) other than the player character 62a act based on the operation of the computer.

  As shown in FIG. 3, for example, when the player character 62a dribbles near the center line 58, the position of the virtual camera 68 is determined based on the position of the ball 66 or the position of the player character 62a holding the ball 66. Is done. For example, the virtual camera 68 moves in the direction in which the player character 62a dribbles. As a result, the ball 66 or the player character 62 a holding the ball 66 is displayed near the center of the game screen 70.

  For example, when the ball 66 is in the vicinity of the center line 58, it is considered that the area that the user wants to see is around the ball 66. Therefore, the player holding the position of the ball 66 or the ball 66 as described above. The virtual camera 68 is controlled based on the position of the character 62a. On the other hand, when the ball 66 is in another position, the region that the user wants to see may be different.

  FIG. 4 is a diagram illustrating a state where the player character 62 a is holding the ball 66 near the touch line 56. As shown in FIG. 4, in the state where the play is performed near the touch line 56a, the region that the user wants to see may be the vicinity of the touch line 56a. Accordingly, the position of the virtual camera 68 is controlled so that the touch line 56a is displayed at a position close to the upper end portion of the game screen 70 and the vicinity of the touch line 56a appears widely.

  For example, when the player character 62a holding the ball 66 dribbles toward the touch line 56a, the position of the virtual camera 68 is controlled so as not to approach the touch line 56a. That is, the Zw coordinate value of the virtual camera 68 is fixed so that the virtual camera 68 does not move in the Zw-axis direction, and the touch line 56a is displayed at a position close to the upper end portion of the game screen 70.

  In addition, for example, when the player character 62 a holding the ball 66 dribbles in a direction parallel to the touch line 56 or passes the ball 66 so as to approach the touch line 56 (for example, the player character 62 b has the ball 66 Since the play is performed near the touch line 56a, it is preferable to display the touch line 56a near the upper end of the game screen 70 as described above.

  On the other hand, when the player character 62a moves the ball 66 in the direction away from the touch line 56a in the vicinity of the touch line 56a, it is conceivable that the region that the user wants to see differs depending on the action of the player character 62a. Therefore, in the present embodiment, the method for controlling the position of the virtual camera 68 differs depending on the action of the player character 62a.

  FIG. 5 is a diagram illustrating a state in which the player character 62 a dribbles near the touch line 56. For example, when the player character 62a dribbles away from the touch line 56a from the state shown in FIG. 4, it is unlikely that the ball 66 moves far. Therefore, in this case, it is considered that the area that the user wants to see is in the vicinity of the touch line 56.

  Therefore, the position of the virtual camera 68 is controlled based on the position of the touch line 56 until the player character 62a moves away from the touch line 56 by a certain distance. That is, the Zw coordinate value of the virtual camera 68 is fixed so that the virtual camera 68 does not move in the Zw axis direction. On the game screen 70, the display position of the touch line 56a is fixed at a position close to the upper end of the game screen 70, and the display position of the player character 62a gradually moves downward.

  On the other hand, when the player character 62a holding the ball 66 in the vicinity of the touch line 56a performs a pass action in a direction in which the ball 66 moves away from the touch line 56a, the virtual camera 68 uses a method different from the dribbling action described above. The position is controlled.

  FIG. 6 is a diagram illustrating a state in which the player character 62a passes. For example, when the player character 62 a passes the ball 66 toward the center of the pitch, the ball 66 moves to a position away from the touch line 56. Accordingly, in this case, since the importance of play in the vicinity of the touch line 56 decreases, it is conceivable that the area that the user wants to see is around the ball 66.

  Therefore, when the player character 62 a performs a pass motion toward the center of the pitch 59, the position of the virtual camera 68 is controlled based on the position of the ball 66. That is, the ball 66 is displayed near the center of the game screen 70 as shown in FIG.

  In this way, for example, the method of controlling the position of the virtual camera 68 differs between when the player character 62a holding the ball 66 near the touch line 56 performs a dribbling action and when a passing action is performed. Thus, the optimum region corresponding to the action of the player character 62a can be confirmed by the user. Hereinafter, the present technology will be described in detail.

[1-3. Functions realized in game device]
FIG. 7 is a functional block diagram showing functions related to the present invention among the functions realized by the game apparatus 10. As shown in FIG. 7, the game apparatus 10 implements a game data storage unit 80, a display control unit 82, a viewpoint control unit 84, and a change unit 86 by executing a game program.

[1-3-1. Game data storage unit]
The game data storage unit 80 is implemented mainly by the main memory 16 and the optical disc 36, for example. The game data storage unit 80 stores data necessary for realizing a soccer game, for example. For example, the case where the game data storage unit 80 stores game situation data indicating the current situation of a game being executed will be described. The game situation data can be said to be data indicating the current situation of the game space 50.

For example, the following data is included in the game situation data.
(1) Data indicating the current state (position, posture, moving direction, moving speed, etc.) of each player character 62 (64) and the current state (position, moving direction, moving speed, etc.) of the ball 66 (2) Data indicating the player character 62 (64) set as the operation target of the user (3) Data indicating the player character 62 (64) holding the ball 66 (4) Position of the pitch 59 and position of the touch line 56 (5) Data indicating the current state of the virtual camera 68 (position, line of sight, gazing point, angle of view, etc.) (6) In addition, the situation of the game (for example, scores and elapsed time of both teams) Data indicating

  Note that the control unit 14 functions as means for acquiring data stored in the game data storage unit 80. The control unit 14 functions as a means for updating data stored in the game data storage unit 80. The data stored in the game data storage unit 80 is not limited to the above example. In addition, for example, various parameters related to the player character 62 (64) may be stored.

[1-3-2. Display control unit]
For example, the display control unit 82 is realized mainly by the control unit 14. The display control unit 82 causes the display unit (for example, the display unit 32) to display an image (for example, the game screen 70) that shows the game space 50 viewed from a given viewpoint (for example, the virtual camera 68).

  For example, the game screen 70 is displayed on the display unit 32 by performing coordinate conversion processing (geometry processing) on an object in the field of view of the virtual camera 68 among the objects arranged in the game space 50. The visual field of the virtual camera 68 is determined based on, for example, the position of the virtual camera 68, the viewing direction, and the angle of view.

[1-3-3. Viewpoint control unit]
For example, the viewpoint control unit 84 is realized mainly by the control unit 14. The viewpoint control unit 84 determines the position of the moving object (for example, the ball 66), the position of the character (for example, the player character 62a) that holds the moving object, the inside of the playing area (for example, the pitch 59), and the outside of the playing area. The position of the viewpoint (for example, the virtual camera 68) is controlled based on at least one of the position of the boundary (for example, the touch line 56).

  That is, the viewpoint control unit 84 is based on any one of the position of the ball 66, the position of the player character 62a holding the ball 66, and the position of the touch line 56, or a combination of two or three. The position of the virtual camera 68 is controlled. The method of controlling the position of the virtual camera 68 by the viewpoint control unit 84 is changed by a changing unit 86 described later. That is, the change unit 86 changes which of the three the viewpoint control unit 84 controls the position of the virtual camera 68.

[1-3-4. Change part]
For example, the changing unit 86 is realized mainly by the control unit 14. The changing unit 86 has a character (for example, a player character 62a) that holds a moving object (for example, the ball 66) near the boundary (for example, the touch line 56) between the game area (for example, the pitch 59) and the outside of the game area. When the operation of moving the moving object in the direction away from the boundary is performed, the control of the position of the viewpoint (for example, the virtual camera 68) by the viewpoint control unit 84 is changed based on the type of the operation.

  “Near the touch line 56” is a position where the distance from the touch line 56 is a predetermined distance or less. The predetermined distance may be a predetermined distance, and may be a distance determined based on the size of the visual field of the virtual camera 68, for example. For example, a distance that is half of the visual field width in the vertical direction among the visual fields of the virtual camera 68 is set as the predetermined distance.

FIG. 8 is a diagram illustrating an area near the touch line 56. As shown in FIG. 8, in the present embodiment, the touch line 56a a distance that the region 100b is within distance reference distance L ₁ between the region 100a or touch lines 56b is within the predetermined distance L ₁ is, touch It is set as an area near the line 56.

  For example, the position of the ball 66 or the player character 62 (64) holding the ball 66 is in the area 100, which corresponds to the case where the player character 62 (64) is holding the ball 66 near the touch line 56. To do.

  The player character 62 (64) holding the ball 66 moves the ball 66 by performing a given action in the region 100, for example. The types of actions performed by the player character 62 (64) may be defined in the game data storage unit 80 in advance. Any of the plurality of action types prepared in advance is performed by the player character 62 (64) holding the ball 66.

For example, the player character 62 (64) holding the ball 66 performs one of the following types of actions.
(Type A) An operation of moving the ball 66 while holding the ball 66 (for example, a dribbling operation or a trapping operation)
(Type B) An operation of moving the ball 66 and changing to a state in which the ball 66 is not held after the operation is performed (for example, a pass operation, a centering operation, a shoot operation, and a clear operation)

  When the operation of type A or type B is performed, the ball 66 moves. In the present embodiment, based on whether the player character 62 (64) holding the ball 66 in the vicinity of the touch line 56 has performed a type A action or a type B action, the virtual camera 68 by the viewpoint control unit 84 is used. The position control method is determined.

  In the present embodiment, the changing unit 86 stores data in which information indicating the type of operation is associated with control information indicating a method for controlling the position of the viewpoint (for example, the virtual camera 68) by the viewpoint control unit 84. A case will be described in which means for acquiring the data from the means for performing is included.

  FIG. 9 is a diagram illustrating correspondence between information indicating the type of operation and control information. The information indicating the type of action includes, for example, which action type the action performed by the player character 62 (64) holding the ball 66 belongs to among the action types defined in the game data storage unit 80. In order to be determined to belong to the determination criteria or the action type for the determination, the condition to be satisfied by the action performed by the player character 62 (64) holding the ball 66 or the action belonging to the action type is satisfied. The condition is stored.

  As the control information, information indicating any one of the position of the ball 66, the position of the player character 62a holding the ball 66, and the position of the touch line 56, or a combination of two or three is stored. The Based on one or a combination of two or three of the position of the ball 66, the position of the player character 62a holding the ball 66, and the position of the touch line 56 indicated by the control information. 68 is controlled.

  In the present embodiment, the changing unit 86 holds the moving object (for example, the ball 66) near the boundary (for example, the touch line 56) between the game area (for example, the pitch 59) and the outside of the game area. When a character (for example, player character 62 (64)) performs an action of moving a moving object in a direction away from the boundary, the viewpoint (by the viewpoint control unit 84) (based on the control information associated with the type of the action) For example, a case where the control of the position of the virtual camera 68) is changed will be described.

  That is, the changing unit 86 identifies which type of action has been performed by comparing the action performed by the player character 62 (64) holding the ball 66 with the association shown in FIG. . For example, it is determined whether or not the action performed by the player character 62 (64) holding the ball 66 satisfies the determination criterion. Further, for example, it is determined whether or not the action performed by the player character 62 (64) holding the ball 66 satisfies the condition shown in FIG.

  In the present embodiment, it is specified whether the player character 62 (64) holding the ball 66 has performed a type A motion or a type B motion. Based on the control information associated with type A or type B, the position of the virtual camera 68 is controlled.

[When operation of type A (dribble operation etc.) is performed]
First, the control of the changing unit 86 when the operation of the type A is performed will be described.

  For example, the changing unit 86 causes the character (for example, the player character 62a) holding the moving object (for example, the ball 66) near the boundary (for example, the touch line 56) to move the moving object from the boundary while holding the moving object. When an action of moving in a direction away (for example, an action of type A) is performed, the viewpoint control unit 84 determines the viewpoint based on the position of the moving object or the position of the character holding the moving object and the position of the boundary. Control the position of

  Here, for simplification of description, a case where the position of the virtual camera 68 is controlled based on the position of the ball 66 and the position of the touch line 56 will be described. In the following description when the action of type A (dribble action or the like) is performed, the description of “position of the ball 66” is “the position of the ball 66 or the position of the player character 62 (64) holding the ball 66”. Can be read as:

  In the viewpoint control unit 84, the positional relationship between the position of the ball 66 and the position of the virtual camera 68 satisfies the first relationship, and the positional relationship between the position of the touch line 56 and the position of the virtual camera 68 is the second position. The position of the virtual camera 68 is controlled so as to satisfy the relationship.

FIG. 10 is a diagram for explaining the position control of the virtual camera 68 when the operation of the type A is performed. As shown in FIG. 10, the first relationship is, for example, the Xw axis component of the vector V ₁ that connects the position of the ball 66 and the position (or gazing point) of the virtual camera 68 (that is, the touch line 56). The directional component or the horizontal component as viewed from the virtual camera 68) is a given vector. That is, the virtual camera 68 moves so as to follow a change in the position of the ball 66 in the direction of the touch line 56.

The second relationship is a relationship in which, for example, the distance between the position (or gazing point) of the virtual camera 68 and the touch line 56 is within a predetermined range, and the distance is a predetermined distance. In other words, the position of the virtual camera 68 is controlled so that the touch line 56 is displayed at a predetermined position on the game screen 70. For example, the touch line 56, the position Q of the gazing point of the virtual camera 68 (position on the viewing direction V ₂ of the virtual camera 68), but so as to have a predetermined distance D _2, the position of the virtual camera 68 is controlled . That is, the position of the virtual camera 68 is controlled so that the virtual camera 68 does not move in a direction orthogonal to the touch line 56.

  As described above, in this embodiment, the position of the virtual camera 68 is controlled so that the position of the virtual camera 68 in the Zw-axis direction (the vertical direction of the touch line 56) does not change, and the virtual camera 68 is moved in the Xw-axis direction. The position of the component is controlled based on the position of the ball 66.

  Note that the method by which the viewpoint control unit 84 controls the position of the virtual camera 68 based on the position of the ball 66 and the position of the touch line 56a is not limited to the above example. On the game screen 70, the ball 66 is displayed at a first position (for example, a position where the horizontal position on the game screen 70 is a predetermined position), and the touch line 56a is displayed at a second position (for example, an end of the game screen 70). The position of the virtual camera 68 may be controlled so that a predetermined position in the vicinity of the section is displayed.

  In the present embodiment, the character (for example, the player character 62a) that holds the moving object (for example, the ball 66) near the boundary (for example, the touch line 56) is held by the changing unit 86 while holding the moving object. When the moving object or the character holding the moving object moves away from the boundary by a predetermined distance or more due to the movement of the moving object away from the boundary, a viewpoint based on the position of the boundary (for example, the virtual camera 68) ) Is limited, and the viewpoint control unit 84 controls the position of the viewpoint based on the position of the moving object or the position of the character holding the moving object.

  For example, when the player character 62 (64) holding the ball 66 dribbles in a direction away from the touch line 56, the changing unit 86 changes the position of the ball 66 or the position of the player character 62 (64) and the touch line. The distance between the positions 56 is calculated, and it is determined whether or not the calculated distance is equal to or greater than a predetermined distance.

  FIG. 11 is a diagram showing the game screen 70 when the distance between the position of the ball 66 or the position of the player character 62 (64) holding the ball 66 and the position of the touch line 56 is a predetermined distance or more. . As shown in FIG. 11, when the player character 62 (64) holding the ball 66 is too far from the touch line 56, the control in which the position of the virtual camera 68 is determined based on the position of the touch line 56 is suppressed. Is done. In this case, the viewpoint control unit 84 determines the position of the virtual camera 68 so that the position of the ball 66 and the position of the virtual camera 68 satisfy a predetermined relationship. That is, as shown in FIG. 11, the ball 66 is displayed near the center.

[When a type B operation (for example, a pass operation) is performed]
Next, the control of the changing unit 86 when the operation of the type B is performed will be described.

  For example, the changing unit 86 is an operation in which a character (for example, a player character 62a) holding a moving object (for example, the ball 66) moves the moving object in a direction away from the boundary, and has performed the operation. When an action (for example, type B action) is performed so that the subsequent character does not hold the moving object, the viewpoint control unit 84 receives a viewpoint (for example, virtual camera 68) based on the position of the moving object. Control the position of

  When the operation of type B is performed, the position of the virtual camera 68 is controlled so that the positional relationship between the position of the ball 66 and the position of the virtual camera 68 satisfies a predetermined relationship. For example, the virtual camera 68 moves based on a change in the position of the ball 66. For example, the position of the virtual camera 68 is controlled so that the positional relationship between the position of the ball 66 and the position of the virtual camera 68 satisfies a predetermined positional relationship. The predetermined positional relationship is, for example, a relationship in which a vector connecting the position of the ball 66 and the position (or gazing point) of the virtual camera 68 becomes a given vector. That is, the virtual camera 68 moves so as to follow the position of the ball 66.

FIG. 12 is a diagram for explaining the control of the position of the virtual camera 68 by the viewpoint control unit 84. As shown in FIG. 12, for example, a position Q that is separated from the position of the ball 66 by a distance D ₁ according to the moving speed of the ball 66 in the moving direction V ₃ of the ball 66 is Thus, the position of the virtual camera 68 is controlled.

  The method for controlling the position of the virtual camera 68 is not limited to the above example. The position of the virtual camera 68 may be controlled so that the position of the ball 66 and the position of the virtual camera 68 maintain a predetermined relationship.

[1-4. Processing executed in game device]
FIG. 13 is a flowchart showing processing executed by the game apparatus 10. This process is executed after a soccer game is started in the game apparatus 10. The control unit 14 executes the process shown in FIG. 13 according to the program stored on the optical disc 36.

First, as shown in FIG. 13, the control unit 14 refers to the game situation data to determine whether or not the player character 62 (64) holding the ball 66 is near the touch line 56 (S1). In S1, for example, the position of the player character 62 (64) for holding a position or ball 66 of the ball 66, the position of the touch line 56, the distance is determined or less than a predetermined distance L ₁ . That is, it is determined whether or not the position of the ball 66 or the position of the player character 62 (64) holding the ball 66 is within the region 100.

  When it is not determined that the player character 62 (64) holding the ball 66 is near the touch line 56 (S1; N), the control unit 14 determines the position of the ball 66 or the player character 62 (64) holding the ball 66. The position of the virtual camera 68 is controlled based on the position (S2). That is, when the position of the ball 66 or the position of the player character 62 (64) holding the ball 66 is an area other than the area 100 in the pitch 59, the position of the ball 66 or the player character 62 holding the ball 66 (64 ) And the position of the virtual camera 68, the position of the virtual camera 68 is determined so as to satisfy a predetermined relationship.

  When it is determined that the player character 62 (64) holding the ball 66 is in the vicinity of the touch line 56 (S1; Y), the control unit 14 causes the player character 62 (64) to move away from the touch line 56. It is determined whether or not an operation for moving the ball 66 is performed (S3). The determination in S3 is performed, for example, by acquiring a change in the position of the ball 66 or a direction instruction operation by a user or a computer.

  When it is determined that the movement of moving the ball 66 in the direction away from the touch line 56 is performed (S3; Y), the control unit 14 specifies the type of the movement (S4). In S4, the operation content of the user or the computer who operates the player character 62 (64) holding the ball 66 is acquired, and the type of action is specified based on the operation content. For example, it is determined whether or not a button on the controller 30 corresponding to “pass operation”, “shoot operation”, or the like has been pressed by the user. Further, for example, it is determined whether or not a computer operation performed based on a predetermined behavior algorithm indicates a “pass operation”, a “shoot operation”, or the like.

  The control unit 14 determines whether or not the type of operation specified in S4 is “dribble operation” or “trap operation” (S5). When it is determined that it is “dribbling motion” or “trap motion” (S5; Y), the control unit 14 determines that the position of the ball 66 or the position of the player character 62 (64) holding the ball 66 is the touch line 56. It is determined whether or not a certain distance or more from (S6).

  When it is not determined that the position of the ball 66 or the position of the player character 62 (64) holding the ball 66 is more than a certain distance from the touch line 56 (S6; N), the control unit 14 determines the position of the virtual camera 68, Control is performed based on the position of the ball 66 or the position of the player character 62 (64) holding the ball 66 and the position of the touch line 56 (S7). In this case, the position of the virtual camera 68 is fixed in the vertical direction of the touch line 56, and the player character 62 in which the virtual camera 68 moves or holds the ball 66 in the horizontal direction of the touch line 56. Follow the movement of (64).

  If it is determined that the distance from the touch line 56 is a certain distance or more (S6; Y), the process proceeds to S2. That is, the execution of the position control in S7 is restricted, and the ball 66 is displayed near the center of the game screen 70.

  On the other hand, when it is not determined that the operation is “dribble operation” or “trap operation” (S5; N), the control unit 14 determines that the type of operation specified in S4 is “pass operation”, “centering operation”, “shoot operation”. "Or" clear operation "is determined (S8).

  When it is determined that the operation is “pass operation”, “centering operation”, “shoot operation”, or “clear operation” (S8; Y), the control unit 14 changes the position of the virtual camera 68 to the position of the ball 66. Based on the control (S9). That is, the position of the virtual camera 68 is controlled so that the ball 66 is displayed near the center of the game screen 70.

  If it is not determined that the operation is “pass operation”, “centering operation”, “shoot operation”, or “clear operation” (S8; N), the process proceeds to S2. In this case, since the ball 66 hardly moves, the process may be shifted to S6.

  Based on the position of the virtual camera 68 determined in S2, S7, or S9, the control unit 14 causes the display unit 32 to display a game screen 70 that shows the game space 50 viewed from the virtual camera 68 (S10). .

  The control unit 14 determines whether an end condition is satisfied (S11). The end condition may be a condition set in advance to end the process. For example, it is determined whether or not the game has ended, or whether or not a given end instruction has been input by the user.

  If it is not determined that the end condition is satisfied (S11; N), the process returns to S1. When it is determined that the end condition is satisfied (S11; Y), this process ends.

  According to the game apparatus 10 described above, by changing the control of the position of the virtual camera 68 according to the type of action performed by the player character 62 (64) holding the ball 66 in the vicinity of the touch line 56, The optimal area that the user wants to see can be displayed on the game screen 70.

  For example, when the player character 62 (64) dribbles near the touch line 56, the touch line 56 is displayed on the game screen 70 so that the user can easily check other player characters 62 (64) near the touch line 56. It is possible to display a wide area within the pitch 59 by displaying near the end of the. When the player character 62 (64) is away from the touch line 56 by a certain distance or more, the ball 66 can be displayed near the center of the game screen 70.

  On the other hand, when the player character 62 (64) passes from the vicinity of the touch line 56 toward the center of the pitch 59, the ball so that the user can easily confirm the player character 62 (64) around the ball 66. The area around 66 can be displayed uniformly.

[2. Modified example]
The present invention is not limited to the embodiment described above. Modifications can be made as appropriate without departing from the spirit of the present invention.

  (1) For example, in the embodiment, the case where the position of the virtual camera 68 is controlled based on the position of the ball 66 when the movement of the type B (for example, the pass movement) is performed has been described. Even when the above operation is performed, it may be preferable that the touch line 56 is displayed on the game screen 70 without the ball 66 being far from the touch line 56.

  For example, when a long pass is made from the vicinity of the touch line 56, the ball 66 is far away from the touch line 56. Therefore, the region that the user wants to see is not the vicinity of the touch line 56 but the periphery of the ball 66. It is conceivable that when a short pass (short pass) is made near the touch line 56, the ball 66 is not so far away from the touch line 56, so that the area that the user wants to see is near the touch line 56. Can be considered.

  In the modified example (1), when the player character 62 (64) holding the ball 66 makes a short pass from the vicinity of the touch line 56, the vicinity of the touch line 56 is displayed on the game screen 70 to thereby display the user. The case where the area that the user wants to see is displayed will be described.

  The changing unit 86 of the modified example (1) causes the character (for example, the player character 62a) holding the moving object (for example, the ball 66) to move the moving object away from the boundary (for example, the touch line 56) by a predetermined distance or more. When the movement is performed and the movement after the movement is performed so that the character does not hold the moving object, the viewpoint control unit 84 receives the viewpoint (based on the position of the moving object). For example, the position of the virtual camera 68) is controlled.

  The changing unit 86 is an operation in which a character (for example, a player character 62a) holding a moving object (for example, the ball 66) moves the moving object so as not to be separated from the boundary (for example, the touch line 56) by a predetermined distance or more. In addition, when an action is performed such that the character after performing the action does not hold the moving object, the viewpoint control unit 84 is caused to perform a viewpoint (based on the position of the moving object and the position of the boundary). For example, the position of the virtual camera 68) is controlled.

  For example, in the association data shown in FIG. 9, as information indicating the type of action, an action of moving the ball 66 away from the touch line 56 by a predetermined distance or longer (for example, a long pass), or the ball 66 from the touch line 56 A condition for performing an operation (for example, a short pass) to move the robot so as not to leave a predetermined distance or more is stored.

  For example, whether or not the player character 62 (64) holding the ball 66 makes a long pass or a short pass is determined based on an operation of the user or the computer. Further, for example, it may be determined whether or not the strength at which the player character 62 (64) kicks the ball 66 is within a predetermined range. When the strength of kicking the ball 66 is equal to or greater than the reference value, the position of the virtual camera 68 is controlled based on the position of the ball 66 and the position of the touch line 56. For example, when the strength of kicking the ball 66 is less than the reference value, the position of the virtual camera 68 is controlled based on the position of the ball 66. The strength with which the player character 62 (64) kicks the ball 66 is also determined based on the operation of the user or the computer.

  According to the modification (1), for example, even if the same pass operation is performed, the position of the virtual camera 68 is controlled so that the periphery of the ball 66 is displayed if the pass is a long pass. For example, the position of the virtual camera 68 can be controlled so that the vicinity of the touch line 56 is displayed.

  (2) Also, for example, when the player character 62 (64) holding the ball 66 moves the ball 66, the ball 66 may be far away from the touch line 56 if the moving speed of the ball 66 is fast. . On the other hand, if the moving speed of the ball 66 is slow, it is conceivable that the ball 66 does not leave the touch line 56 much.

  For example, even if the player character 62 (64) holding the ball 66 performs a pass action from the vicinity of the touch line 56 toward the center of the pitch 59, if the ball 66 moves slowly, the player character 62 (64) moves from the touch line 56. Since the ball 66 is not so far away, it is conceivable that the area that the user wants to confirm is near the touch line 56. On the other hand, if the ball 66 moves fast, the ball 66 moves away from the touch line 56, so the area that the user wants to check is considered to be around the ball 66.

  In the modified example (2), a case where the player character 62a holding the ball 66 changes the control method of the position of the virtual camera 68 based on the moving speed of the ball 66 when the player performs a pass action, for example. To do.

  The game apparatus 10 of the modified example (2) includes a moving speed determination unit that determines whether or not the moving speed of the moving object (for example, the ball 66) is equal to or higher than a reference speed. This means is realized mainly by the control unit 14. The reference speed may be a predetermined speed. For example, a value indicating the moving speed of the ball 66 stored in the game situation data is referred to, and it is determined whether or not the value is equal to or greater than a predetermined threshold value.

  The change unit 86 of the modified example (2) moves the character holding the moving object in the direction away from the boundary near the boundary (for example, the touch line 56) between the competition area (for example, the pitch 59) and the outside of the competition area. When an operation of moving an object (for example, the ball 66) is performed, the viewpoint control unit 84 controls the position of the viewpoint (for example, the virtual camera 68) based on the type of the operation and the determination result of the moving speed determination unit. change.

  For example, the changing unit 86 includes a unit that acquires data from a unit that stores data in which information indicating the type of motion, information indicating a determination result of the moving speed determination unit, and control information are associated with each other. Will be explained.

  FIG. 14 is a diagram illustrating a correspondence between information indicating the type of motion, information indicating the determination result of the moving speed determination unit, and control information. As shown in FIG. 14, as the information indicating the determination result of the moving speed determining means, a condition indicating whether or not the moving speed of the ball 66 is equal to or higher than the reference speed is stored. The changing unit 86 changes the control of the position of the viewpoint by the viewpoint control unit 84 based on the control information associated with the type of operation and the determination result of the moving speed determination unit.

  For example, when the value indicating the moving speed of the ball 66 is equal to or greater than the threshold value, the ball 66 may move far. Therefore, the position of the virtual camera 68 is controlled so that the periphery of the ball 66 is displayed uniformly. Is done. Further, for example, when the value indicating the moving speed of the ball 66 is less than the threshold value, it is difficult to think that the ball 66 moves far, so that the position of the virtual camera 68 is fixed in the vicinity of the touch line 56. The position of the virtual camera 68 is controlled.

  According to the modification (2), even if a predetermined type of action is performed by the player character 62 (64) holding the ball 66, the vicinity of the touch line 56 is displayed according to the moving speed of the ball 66. Or whether the surroundings of the ball 66 are displayed uniformly.

  (3) Also, for example, when the player character 62a performs a pass action, the ball 66 is considered to move farther if the ball 66 is a pass that rises high from the pitch 59 (for example, a long pass). However, if the path of the ball 66 is not so far from the pitch 59 (for example, a short path), the possibility that the ball 66 moves far is low. It is preferable to fix in the vicinity of the touch line 56.

  In the modified example (3), when the player character 62a holding the ball 66 performs a pass action, for example, the position of the virtual camera 68 is controlled based on whether or not the ball 66 is lifted high from the pitch 59. The case where it is changed will be described.

  The game apparatus 10 according to the modification (3) includes a height determination unit that determines whether or not a moving object (for example, the ball 66) moves to a reference height or higher. This means is realized mainly by the control unit 14. The reference height may be a predetermined height in the vertical direction (Yw axis direction) of the game space 50. For example, the position of the ball 66 stored in the game situation data is referred to, and it is determined whether or not the distance between the ball 66 and the pitch 59 is a predetermined distance or more. Further, for example, it may be determined whether or not the angle formed by the moving direction of the ball 66 and the pitch 59 is a predetermined angle or more.

  The changing unit 86 also has a character (for example, a player character 62a) that holds a moving object (for example, the ball 66) near the boundary (for example, the touch line 56) between the game area (for example, the pitch 59) and the outside of the game area. ) Performs an operation of moving a moving object in a direction away from the boundary (for example, a path operation), based on the type of the operation and the determination result of the height determination unit (for example, the viewpoint (for example, The control of the position of the virtual camera 68) is changed.

  For example, the changing unit 86 includes a unit that acquires data from a unit that stores data in which information indicating the type of operation, information indicating the determination result of the height determination unit, and control information are associated with each other. Will be explained.

  FIG. 15 is a diagram illustrating a correspondence between information indicating the type of operation, information indicating the determination result of the height determination unit, and control information. As shown in FIG. 15, as the information indicating the determination result of the height determination unit, a condition indicating whether or not the height of the ball 66 is equal to or higher than the reference height is stored. The changing unit 86 changes the control of the position of the viewpoint by the viewpoint control unit 84 based on the control information associated with the type of operation and the determination result of the moving speed determination unit.

  For example, when the ball 66 is lifted from the pitch 59 to a reference height or more, it is conceivable that the ball 66 moves far away, so that the surroundings of the ball 66 are displayed based on the position of the ball 66 so as to be displayed uniformly. The position of the camera 68 is controlled. Further, for example, when the ball 66 is not lifted from the pitch 59 to a reference height or more, it is unlikely that the ball 66 moves far away, so that the position of the virtual camera 68 is fixed in the vicinity of the touch line 56. Based on the position of the touch line 56 and the position of the ball 66, the position of the virtual camera 68 is controlled.

  According to the modification (3), even when a predetermined type of action is performed by the player character 62 (64) holding the ball 66, the vicinity of the touch line 56 is determined according to the height at which the ball 66 is lifted. Can be displayed or whether the periphery of the ball 66 can be displayed uniformly.

  (4) Also, for example, when a game in which teams to which a plurality of characters (for example, player characters 62 (64)) play against each other is executed as in the embodiment, the pass action may fail. For example, even if the player character 62a performs a pass action from the vicinity of the touch line 56, if it is predicted that the player character 64 belonging to the opponent team will pass a cut, the virtual camera 68 is set to the vicinity of the touch line 56. It may be preferable to fix with.

  In the modified example (4), a case will be described in which the control of the position of the virtual camera 68 is changed based on whether or not the pass operation is successful.

  In the game device 10 of the modified example (4), a character (for example, a player character 62a) holding a moving object (for example, the ball 66) performs a pass action to another character belonging to the same team as the character. The position of the moving object or the character that performed the pass action, the moving direction of the moving object or the position of another character (for example, the player character 62b), and the character belonging to a different team from the character that performed the pass action Based on the position (for example, player character 64), it is determined whether or not the pass action is successful.

  FIG. 16 is a diagram for explaining a method of determining whether or not the pass operation is successful. As shown in FIG. 16, when the player character 62a performs a pass action, the dominating area 110 (the dominating areas 110a and 110b shown in FIG. 16) is added to the game space 50 based on the position of the player character 64 belonging to the opponent team. Is set. The dominating area 110 is an area including the position of the player character 64, and is, for example, an area within a circle having a predetermined radius centered on the position of the player character 64.

For example, when the straight line from the position of the ball 66 toward the moving direction V ₄ (pass direction) does not intersect the dominant area 110 of the player character 64, it is determined that the pass action is successful. On the other hand, for example, when a straight line from the position of the ball 66 toward the moving direction V ₄ (pass direction) intersects the dominant area 110 of the player character 64, it is determined that the pass action fails.

  The method for determining whether or not the pass operation is successful is not limited to the above example. For example, by determining whether or not the dominant region 110 of the player character 64 is on a straight line connecting the position of the player character 62a performing the pass action and the position of the player character 62 that is the opponent of the pass, It may be determined whether or not the pass operation is successful. In addition, for example, based on the distance between the straight line from the position of the ball 66 in the moving direction and the position of the player character 64, it may be determined whether or not the pass action is successful.

  The change unit 86 of the modified example (4) includes a character (for example, a ball 66) that holds a moving object (for example, the ball 66) near the boundary (for example, the touch line 56) between the game area (for example, the pitch 59) and the outside of the game area. When the player character 62a) performs a pass motion in a direction away from the boundary and it is determined that the pass motion is successful, the viewpoint control unit 84 determines the viewpoint (for example, the virtual camera 68) based on the position of the moving object. ) Is controlled.

  On the other hand, the changing unit 86 is a character (for example, a player character 62a) that holds a moving object (for example, the ball 66) near the boundary (for example, the touch line 56) between the competition area (for example, the pitch 59) and the outside of the competition area. ) Performs a path movement in a direction away from the boundary and determines that the path movement fails, the viewpoint control unit 84 determines the viewpoint (for example, virtual camera) based on the position of the moving object and the position of the boundary. 68) is controlled.

  If it is determined that the pass operation is successful, the ball 66 may move far. Therefore, the position of the virtual camera 68 is controlled based on the position of the ball 66 so that the periphery of the ball 66 is displayed uniformly. Is done. On the other hand, for example, when it is determined that the pass operation has failed (that is, when the pass cut is performed in the vicinity of the touch line 56), it is unlikely that the ball 66 moves far away. The position of the virtual camera 68 is controlled based on the position of the touch line 56 and the position of the ball 66 so that the position of the virtual camera 68 is fixed.

  According to the modification (4), even when the pass action is performed by the player character 62 (64) holding the ball 66, the vicinity of the touch line 56 is determined based on whether or not the pass action is successful. It is possible to switch between displaying and displaying the periphery of the ball 66 uniformly.

  (5) Also, for example, when the player character 62 (64) holding the ball 66 performs a pass motion, another player character 62 (64) is located on the moving direction side of the ball 66 in the region 100 near the touch line 56. If so, the other player character 62 (64) may hold the ball 66 near the touch line 56. In this case, it is conceivable that the ball 66 is positioned in the vicinity of the touch line 56, and therefore it is preferable to cause the second viewpoint control unit 86 to control the virtual camera 68.

  Therefore, in the modified example (5), when the ball 66 is moved in the vicinity of the touch line 56, whether or not the player character 62 (64) is on the moving direction side of the ball 66 in the region 100 in the vicinity of the touch line 56. The case where it is determined whether or not to switch the control of the position of the virtual camera 68 will be described.

  In the game device 10 of the modification (5), when the character holding the moving object (for example, the ball 66) moves the moving object, the moving direction as viewed from the moving object in the vicinity of the boundary (for example, the touch line 56). Character determination means for determining whether there is another character (for example, player character 62b) on the side is included. This means is realized by the control unit 14.

  The movement direction side of the ball 66 is in an area including a position separated from the position of the ball 66 by a predetermined distance in the movement direction of the ball 66. For example, of the player characters 62 (64) in the touch line 56, it is determined whether or not there is a player character 62 (64) whose distance from a current line of the ball 66 extending in the moving direction is within a predetermined distance. Is done.

  The change unit 86 of the modified example (5) includes a character (for example, a ball 66) that holds a moving object (for example, the ball 66) near the boundary (for example, the touch line 56) between the game area (for example, the pitch 59) and the outside of the game area. When the player character 62a) moves the moving object in a direction away from the boundary, the control of the position of the viewpoint by the viewpoint control unit is changed based on the type of the motion and the determination result of the character determination unit. .

  For example, the changing unit 86 includes a unit that acquires data from a unit that stores data in which information indicating the type of motion, information indicating the determination result of the character determination unit, and control information are associated with each other. explain.

  FIG. 17 is a diagram illustrating correspondence between information indicating the type of action, information indicating the determination result of the character determination unit, and control information. As shown in FIG. 17, as information indicating the determination result of the character determination means, a condition indicating whether or not the player character 62 (64) is on the moving direction side of the ball 66 in the vicinity of the touch line 56 is stored. The changing unit 86 changes the control of the position of the viewpoint by the viewpoint control unit 84 based on the control information associated with the type of action and the determination result of the character determination unit.

  When it is determined that there is no other player character 62 (64) on the moving direction side of the ball 66, it is considered that the ball 66 moves far. Therefore, the ball 66 is displayed so that the periphery of the ball 66 is displayed uniformly. Based on the position, the position of the virtual camera 68 is controlled. On the other hand, for example, when it is determined that there is another player character 62 (64) on the moving direction side of the ball 66, it is difficult to think that the ball 66 moves far away. The position of the virtual camera 68 is controlled based on the position of the touch line 56 and the position of the ball 66 so that the position is fixed.

  According to the modification (5), whether or not there is a player character 62 (64) on the moving direction side of the ball 66 even when a pass action is performed by the player character 62 (64) holding the ball 66. Accordingly, it is possible to switch between displaying the vicinity of the touch line 56 and displaying the periphery of the ball 66 uniformly.

  (6) For example, even when the player character 62 a holding the ball 66 is in the vicinity of the touch line 56, there is sufficient pitch 59 area in the game screen 70 depending on the position of the virtual camera 68 and the direction of the line of sight. And the control of the position of the virtual camera 68 does not have to be changed by the changing unit 86 in some cases.

  FIG. 18 is a diagram illustrating an example of the game space 50. For example, in a situation where the player character 62a holds the ball 56 near the touch line 56 and the virtual camera 68 is on the back side of the player character 62a, on the game screen 70, near the touch line 56 and the ball 66. The surroundings are displayed relatively wide.

  FIG. 19 is an example of the game screen 70 displayed when the virtual camera 68 is positioned on the back side of the player character 62 a holding the ball 66. When the line-of-sight direction of the virtual camera 68 faces the direction of the touch line 56, the pitch 59 is displayed relatively wide on the game screen 70 as shown in FIG. That is, since the angle of view of the virtual camera 68 is set based on the aspect ratio (for example, 16: 9 or 4: 3) of the display unit 32, in the case of the display unit 32 having a horizontally long screen, FIG. Thus, even when the ball 66 is near the touch line 56, the pitch 59 is displayed widely.

  In such a case, even if the position of the virtual camera 68 is not controlled based on the position of the touch line 56, the user fully checks the vicinity of the touch line 56 and also uniformly checks the periphery of the ball 66. Therefore, the change unit 86 may not change the position control of the virtual camera 68.

  The game apparatus 10 according to the modified example (6) determines whether or not an angle (for example, an angle θ illustrated in FIG. 18) formed by the visual line direction of the viewpoint and a boundary (for example, the touch line 56) is equal to or greater than a predetermined angle. . In other words, it is determined whether or not the line-of-sight direction of the virtual camera 68 faces the direction of the touch line 56. For example, the angle θ shown in FIG. 18 is acquired by comparing the line-of-sight direction of the virtual camera 68 stored in the game situation data with the direction of the touch line 56. The predetermined angle may be a predetermined angle (for example, 45 °).

  When it is determined that the angle formed between the line-of-sight direction of the viewpoint (for example, the virtual camera 68) and the boundary (for example, the touch line 56) is equal to or greater than the predetermined angle, the game device 10 performs the change of the viewpoint control unit 84. Change control. That is, when the line-of-sight direction of the virtual camera 68 is nearly perpendicular to the touch line 56, an area that the user wants to see cannot be displayed depending on the action of the player character 62 (64) holding the ball 66. Therefore, the control of the viewpoint control unit 84 is changed by the changing unit 86.

  On the other hand, when the game device 10 determines that the angle formed between the line-of-sight direction of the viewpoint (for example, the virtual camera 68) and the boundary (for example, the touch line 56) is less than the predetermined angle, the game device 10 restricts the change by the changing unit 86. Then, the viewpoint control unit 84 controls the position of the viewpoint based on the position of the moving object (for example, the ball 66) or the position of the character (for example, the player character 62a) holding the moving object. For example, when the line of sight of the virtual camera 68 faces the direction of the touch line 56, the vicinity of the touch line 56 can be displayed and the surroundings of the ball 66 can be displayed in an easy-to-see manner. 84 is not controlled.

  According to the modified example (6), when it is easy to confirm the vicinity of the ball 66 while checking the vicinity of the touch line 56 without changing the control of the position of the virtual camera 68 by the changing unit 86, the changing unit The change by 86 can be suppressed. Therefore, an increase in the processing load on the game apparatus 10 due to changing the control of the position of the virtual camera 68 can be suppressed.

  (7) For example, the boundary of the pitch 59 has been described as the touch line 56, but the boundary may be the goal line 54. In this case, the changing unit 86 changes the control of the position of the virtual camera 68 according to the type of action of the player character 62 (64) holding the ball 66 near the goal line 54.

  (8) For example, in the embodiment and the above-described modification, the case where the action of type A or the action of type B is performed has been described, but the position of the virtual camera 68 is determined according to the type of action performed in the soccer game. What is necessary is just to make it change control. In addition, for example, a slow-in operation may be performed near the touch line 56. When the throw-in operation is performed, the control method of the virtual camera 68 may be changed depending on whether or not the long throw is performed, similarly to the content described in the case of the pass operation.

  (9) Further, for example, the game space 50 has been described as a three-dimensional space as shown in FIG. 2, but the game space according to the present invention has two coordinates such as the position of the player character 62 (64) and the ball 66. It may be a two-dimensional game space managed by elements.

  (10) For example, the present invention can also be applied to a game device that executes a game other than a soccer game. The present invention can be applied to a game in which a character moves a moving object within a competition area. For example, the present invention can be applied to a game device that executes a basketball game, an ice hockey game, an American football game, or the like.
