  As shown in FIG. 3A, the third person viewpoint (objective viewpoint) is one in which a viewpoint (virtual camera) is arranged behind the player character on the player side, and on the game screen, as shown in FIG. The whole body of the player character on the side is projected.

  As shown in FIG. 3B, the first person viewpoint (subjective viewpoint) is one in which the viewpoint (virtual camera) is arranged at almost the eye position of the player character on the self side, and as shown in FIG. 5 on the game screen. In addition, only the arm and the racket are projected for the player player character on the near side, and the whole body is not projected.

<Operation>
FIG. 6 is a flowchart showing an example of viewpoint control processing in the above embodiment, which is an example of a tennis video game.

  In FIG. 6, when the play performed from the serve to the point acquisition is started (step S101), the viewpoint control unit 104 (FIG. 1) sets the third person viewpoint mode (step S102). The start of play is the timing of switching to the third person viewpoint mode.

  FIG. 7 (a) shows an example of processing for setting the third person viewpoint mode. When the processing is started (step S201), the player character of the player's own character in the model data 106 (FIG. 2 (a)) is displayed. Based on the model (step S202), the third-person viewpoint offset of the control setting data 107 (FIG. 2B) is set to the viewpoint offset O of the game situation data 108 (FIG. 2C) to move the viewpoint. Is performed (step S203), and the process is terminated (step S204). Although only the display of the player player character is shown as related to the viewpoint control, naturally other models are also displayed in parallel.

  Returning to FIG. 6, a branch is made depending on whether or not the opponent player character serves (step S103). If the opponent player character serves (Yes in step S103), whether or not the opponent player character has hit the ball It is determined whether or not (step S104). In addition, although the judgment of hit | damage here is the hit | damage by a serve at the first time, it becomes a hit | damage by the rally on the way in the subsequent judgment.

  Whether or not the opponent player character has hit the ball (step S104) is determined by the opponent side racket position coordinate R2, the opponent side racket surface normal vector N2, and the ball position B in the game situation data 108 (FIG. 2C). And the ball velocity vector V and the contact determination between the ball and the racket surface based on the opponent side racket surface range of the control setting data 107 (FIG. 2B). That is, as shown in FIG. 8, it is determined that the ball and the racket surface are in contact with each other when the ball position B matches the two-dimensional coordinate range of the opponent racket surface range surrounding the opponent racket position coordinate R2. At this time, since the determination is performed at a predetermined time interval (for example, every frame of screen drawing), an approach within a distance obtained by multiplying the ball speed vector V by the determination interval time is determined as a contact.

Returning to FIG. 6, if it is determined that the opponent player character has hit the ball (Yes in Step S104), it is then determined whether or not the ball is facing the player character (Step S105). The determination as to whether or not the ball is facing the player character (step S105) is made based on the ball speed vector V and the player player position coordinate P1 in the game situation data 108 (FIG. 2C). . That is, as shown in FIG. 9, the Z-axis component of the ball velocity vector V is V _Z , the Z-axis component of the player side player character position coordinate P1 is P1 _Z ,
V _Z · _{P1 Z>} 0
If so, it is determined that the ball is facing the player character from the opponent's court.

  Returning to FIG. 6, when it is determined that the ball is facing the player character (Yes in step S105), the mode is switched to the first person viewpoint mode (step S106). The detection that the ball is heading toward the player character is the timing for switching to the first person viewpoint mode.

  FIG. 7B shows an example of processing for switching to the first person viewpoint mode. When the processing is started (step S211), the display of the player player character is erased (step S212), and the model data 106 (FIG. 2) is displayed. The self-side arm / racquet is displayed based on the self-side arm / racquet model of (a)) (step S213), and the control setting data 107 (FIG. 2) is added to the viewpoint offset O of the game situation data 108 (FIG. 2 (c)). The first-person viewpoint offset of (b)) is set and the viewpoint is moved (step S214), and the process ends (step S215).

  Returning to FIG. 6, after switching to the first-person viewpoint mode (step S106) or when it is not determined that the opponent player character has hit the ball (No in step S104), the ball is directed toward the player player character. If it is not determined that the point has been determined (No in step S105), it is determined whether or not the point has been determined by the opponent's batting or the like (step S107). In the case of a serve, the game is often organized so that it can be continued until the ball is hit, and when the opponent's served ball does not enter the service court of the self-side court, it becomes a point on the self side. In the middle of the rally, in addition to the case where the ball hit by the opponent does not enter the court on the opponent's side, it becomes a point on the opponent's side by skipping the opponent or missing the ball.

  If it is not determined that the opponent has hit a point (No in step S107) or if the player player character serves (No in step S103), it is determined whether or not the player player has hit the ball. (Step S108). In addition, the hit | damage here has the case of the hit | damage by a serve and the case of the hit | damage by the rally in the middle. Further, when the self player character serves (No in step S103), the third person viewpoint mode is maintained, but the first person viewpoint mode may be switched immediately before the serve operation can be performed.

  Further, when the self player character is struck, the movement of the motion controller 2 (up / down / left / right movement and rotation) and the movement of the self player character's racket (up / down / left / right movement and rotation) are synchronized.

  It is determined whether or not the player character has hit the ball (step S108). The player side racket position coordinate R1, the player side racket surface normal vector N1, and the ball position B in the game situation data 108 (FIG. 2C). And the ball velocity vector V and the contact determination between the ball and the racket surface based on the self-side racket surface range of the control setting data 107 (FIG. 2B). The details are the same as described with reference to FIG.

  Returning to FIG. 6, when it is determined that the player character has hit the ball (Yes in step S108), the mode is switched to the third person viewpoint mode (step S109). The detection that the player character has hit the ball is the timing for switching to the third person viewpoint mode.

  FIG. 7C shows an example of processing for switching to the third person viewpoint mode. When the processing is started (step S221), the display of the self-side arm / racquet is erased (step S222), and the model data 106 (FIG. The self-side player character is displayed based on the self-side player character model (2 (a)) (step S223), and the control setting data 107 (FIG. 2 (FIG. 2 (c)) is added to the viewpoint offset O of the game situation data 108 (FIG. 2 (c)). The third person viewpoint offset of b)) is set and the viewpoint is moved (step S224), and the process is terminated (step S225).

  Returning to FIG. 6, after switching to the third-person viewpoint mode (step S109), or when it is not determined that the player character has hit the ball (No in step S108), points are given by hitting on the player side, etc. It is determined whether it has been decided (step S110). In the case of a serve, the game is often set up so that it can be continued until the ball is hit, and when the self-served ball does not enter the service court of the opponent's court, it becomes the opponent's point. In the middle of the rally, in addition to the case where the ball hit by the player does not enter the opponent's court, the player's point will be scored by the player's own swing or missed ball.

  If it is not determined that the point has been determined by the hitting on the side of the player (No in step S110), the process returns to the determination of whether the opponent player character has hit the ball (step S104).

  When it is determined that the points have been determined (Yes in step S107, Yes in step S110), after playing a video such as an emotion expression scene that expresses the joy and sadness of the player, the play ends (step S111). ) If the game is not over, the next play is started.
