Description

  The present invention relates to a game apparatus and a computer-readable recording medium on which a game program is recorded, and more particularly to a game apparatus that advances a game by performing three-dimensional display of a game image and a computer-readable recording medium on which the game program is recorded.

  Conventionally, there is a game device that displays a game image of a baseball game and executes the game. In such a game device, the game is divided between the defender side and the attack side in a battle format of two players or a battle format of one player and a computer.

  In a conventional baseball game, a three-dimensional display of the game is performed. For example, after a batter on the attacking side hits a pitch, the defense side catches the ball and sends it, for example, from a camera placed over the back net. The camera angle screen overlooking the entire stadium is displayed in a fixed manner. On this screen, the defensive player operates the fielder to catch the hit ball.

  In a baseball game that is fixedly displayed on a camera angle screen overlooking the entire baseball stadium, when the hit ball is a fly, the falling point is indicated by X on the ground, and the player on the defensive side drops the fielder by X I just moved to the spot and waited for the hit ball to fall.

  However, various camera angles are used to display the baseball game in a more realistic manner. For example, it is close to the fielder's line of sight until the attacking batter hits the fly and the defender catches the ball and sends it. If you try to display the ball as if it was shot at an angle, the ground will not be displayed on the screen where the fielder looks up at the fly ball, even if you try to indicate the point of fall on the ground with an X mark. There was a problem that it was not possible to indicate where the hit ball fell.

  FIG. 1 shows a block diagram of an embodiment of the game apparatus of the present invention. In the figure, in a recording medium 10 such as a CD-ROM, a game program 12 for controlling the movement of an object including a game story and characters in synchronization with the progress of the game, a drawing program for performing image processing, and segment data In addition, a drawing library 14 such as texture data is recorded. The recording medium 10 is mounted on a playback device 21 that constitutes the hardware 20 of the game device, and is read as necessary to execute a game program and a drawing program. Here, an object to be displayed in the virtual space is called a segment, and the segment is composed of a polygon which is a display element or a plurality of vertices constituting the polygon.

  In the hardware 20 of the game apparatus, the CPU 22 that performs various arithmetic processes including matrix calculation for coordinate conversion, visual field conversion calculation, and the like, and the data from the recording medium 10 are buffered and used as a work area for arithmetic processing. A system memory (RAM) 24 is connected by a bus. Further, the CPU 22 is connected via a bus arbiter 26 to a drawing processor 28 for drawing according to a drawing command, a frame memory 30 to which image data drawn by the drawing processor 28 is written, an audio processor 32 for generating audio data, An audio memory 34 to which audio data generated by the audio processor 32 is written is connected.

  The drawing processor 28 generates segment image data based on the drawing command and image data (polygon data and segment image data) supplied from the CPU 22, and specifies which segment is in front of the viewpoint. The texture data is read and applied to the polygon to be displayed, and the texture data is rendered.

  The image data read from the frame memory 30 and the audio data read from the audio memory 34 are supplied to a display device 35 such as a television monitor, and a game screen is displayed and game audio is output.

  The bus arbiter 26 has a function as an interface, and is connected to the playback device 21 and the game input operation pad 36 and to an external communication line via a modem 37. The bus arbiter 26 is also connected to a boot ROM 38, and a boot operation at power-on is performed by executing a program in the boot ROM 40.

  FIG. 2 is a plan view of an embodiment of the input operation pad 36. In the figure, an input operation pad 36 includes an analog cross key 40, an A button 42, a B button 43, an X button 44, a Y button 45, and an L button 46, an R button 47, an S button 48, and a cross key 49. Etc. are provided. When the player is a fielder, the analog cross key 40 is used to instruct the direction in which the fielder moves for catching, and the ball caught by the A button 42, B button 43, X button 44, and Y button 45 is sent. It has a function to instruct you to do.

  FIG. 3 shows a flowchart of an embodiment of a ball catching processing routine executed by the CPU 22 of the apparatus of the present invention. In this processing routine, screen display is performed at a camera angle for shooting in the main base direction (or the center direction) from a camera placed behind the fielder (object) to be caught according to the hit ball position. In addition, the camera angle to shoot toward the center direction is when the catcher catches the catcher goro, the state where it is not decided which fielder catches immediately after hitting, and the fielder other than the catcher catches the ball Is the camera angle to shoot in the direction of the home.

  In the figure, in step S10, it is determined whether the hit ball is fly or goro from the elevation angle of the hit ball (ball: target). If the hit ball is a goro, the process proceeds to step S12, and the CPU 22 selects the fielder that can reach and hit the ball fastest from the direction and speed of the hit ball and the position and running speed of each fielder. An arrow-shaped catch marker is displayed over the fielder's head. This catching marker indicates the movement direction of the fielder. Thereafter, the ball catching process is performed in step S14, and when the ball catching is completed, the process routine is terminated and the process proceeds to the ball sending process.

  On the other hand, if the hit ball is a fly, the process proceeds to step S20, where the CPU 22 calculates a hit point (target position) of the hit ball from the direction and speed of the hit ball, and displays a drop point marker at this drop point. The drop point marker is a translucent blue columnar shape having a predetermined height (= h1) larger than the height of the fielder and a diameter that only surrounds the fielder, and is displayed in a standing state on the ground point. . Further, in step S22, a fielder that can reach the falling point fastest and catch a ball is selected from the position and running speed of each fielder, and an arrow-shaped ball catching marker is displayed on the head of the selected fielder. This catching marker indicates the fielder's moving direction and catching direction.

  Next, in step S24, the selected fielder is moved to the position where the drop point marker is displayed by the operation of the analog cross key 40 by the player or the control of the CPU. In this step S24, the screen display is performed by sequentially changing the camera angle so that the hit ball can be seen from the camera placed behind the fielder in accordance with the position of the fly ball and the position of the fielder. Here, the fielder 50, the hit ball 52, and the catch marker 54 are displayed on the screen immediately after the hit shown in FIG. 4, but the drop point marker is not yet displayed because the fielder 50 is far from the drop point. In the subsequent screen shown in FIG. 5, since the fielder has approached the falling point, a fielder 50, a hit ball 52, a catching marker 54, and a translucent blue falling point marker 56 are displayed.

  Thereafter, in step S26, it is determined whether or not the fielder has reached the drop point marker before the fly hit ball falls to the ground, and if it cannot be reached, the fly hit ball cannot be caught. It progresses to S14 and a ball catching process is performed. If it can be reached, the process proceeds to step S28, and the fall point marker is changed from translucent blue to translucent green. On the screen shown in FIG. 6, a fielder 50, a hit ball 52, a catching marker 54, and a drop point marker 58 changed to a translucent green are displayed. Thereafter, the process proceeds to step S30, in which the CPU 22 automatically rotates until the fielder faces the falling direction of the fly ball. At this time, how much the fielder rotates depends on the falling direction of the fly ball and the direction from which the fielder has reached the drop point marker.

  Next, in step S32, it is determined whether or not the fielder has been able to rotate in the direction in which the ball hits the ball to the angle at which the fielder can catch the ball before falling to the height position where the fielder can catch the ball. If the fielder can rotate to an angle at which he can catch the ball, in step S34, the height of the drop point marker is deformed to about h1 / 2 and is changed to translucent yellow. Thereafter, the ball is caught when the hit ball falls to a height position where the fielder catches in step S36. On the screen shown in FIG. 7, a fielder 50, a hit ball 52, a catch marker 54, and a drop point marker 60 that is ½ in height and translucent yellow are displayed. Thereafter, the processing routine is terminated and the ball sending process is performed. On the other hand, if the fielder cannot rotate to an angle at which he can catch the ball, he / she cannot catch the fly ball, so the process proceeds to step S14 to perform the ball catching process.

  In this way, since the marker indicating the drop point where the ball arrives is displayed according to the change of the camera angle, the drop point can be displayed in an easy-to-understand manner even if the camera angle of the three-dimensional display is changed. By displaying in three dimensions, the target position can be displayed in an easy-to-understand manner even if the camera angle of the three-dimensional display is changed. Furthermore, since the display form of the marker is changed according to the state of the fielder with respect to the target position, the state of the fielder with respect to the target position can be known from the display form of the marker.

  By the way, as described above, in the catching processing routine, the screen is displayed at the camera angle taken from the camera placed behind the fielder trying to catch according to the hitting position, and the catcher catches the catcher goro. In this case, the camera angle is taken in the direction of the center, and when a fielder other than the catcher catches the ball, the camera angle is taken in the direction of the main base.

  Here, when the A button 42 is fixed to the second base side, the B button 43 is fixed to the third base side, the X button 44 is fixed to the first base side, and the Y button 45 is fixed to the main base side, when a fielder other than the catcher catches the ball If the camera angle is shooting in the direction of the main base, the player will not be confused, but if the catcher catches the catcher goro, it is the camera angle that is shot in the direction of the center. Since the button position of the operation pad 36 is reversed left and right, the player may be confused and misoperate. An embodiment which tries to eliminate this error will be described.

  FIG. 8 shows a flowchart of an embodiment of a button switching processing routine executed by the CPU 22 of the apparatus of the present invention. In step S40, a throwing screen is displayed. As shown in FIG. 9, the throwing screen has a camera angle for photographing in the direction of the center from the camera placed behind the catcher. In FIG. 9, a pitcher 62 and a batter 64 are displayed.

  In step S42, it is determined whether stealing or striking has been performed. If stealing has been performed, the process proceeds to step S44, where the camera angle taken from the camera behind the catcher toward the center is prevented from stealing. In step S45, the A button 42 corresponds to the home base, the B button 43 corresponds to the first base, the X button 44 corresponds to the third base, and the Y button 45 corresponds to the second base in step S45. Then, the button operation of the player's input operation pad 36 is read. Thereafter, the processing routine is terminated, and the process proceeds to a process corresponding to the button operation on the input operation pad 36.

  On the other hand, if a hit is made, the process proceeds to step S46, where the screen is displayed at a camera angle for shooting in the direction of the main ball from the camera placed behind the fielder trying to catch the ball according to the hitting position. 3 is executed.

  When the catching process is completed, the process proceeds to step S48, where it is determined whether the catching position is the center side or the main base side from the line connecting the first and third bases. Here, if the catching position is the center side, the process proceeds to step S50, and as shown in FIG. 10, from the camera placed at a position where at least two catches behind the catched fielder can be seen toward the main base direction. In step S51, the A button 42 is set to 2 mm, the B button 43 is set to 3 mm, the X button 44 is set to 1 mm, and the Y button 45 is switched to the main screen in step S51. And the button operation of the player's input operation pad 36 is read. In FIG. 10, a pitcher 62, a batter 64, a two-hander 66, a catcher 68, and the like are displayed. Thereafter, the processing routine is terminated, and the process proceeds to a process corresponding to the button operation on the input operation pad 36.

  If the catching position is on the home base side, the process proceeds to step S52, and as shown in FIG. 11, the screen display is performed at the camera angle that shoots toward the center from the camera placed behind the catching fielder. In step S53, according to the pitching screen, the A button 42 is switched to the main player, the B button 43 is changed to the first button, the X button 44 is changed to the third button, and the Y button 45 is changed to the second button. 36 button operations are read. In FIG. 11, a pitcher 62, a batter 64, a two-hander 66, a catcher 68, and the like are displayed. Thereafter, the processing routine is terminated, and the process proceeds to a process corresponding to the button operation on the input operation pad 36.

  In this way, even if the camera angle is changed according to the position of the ball and the direction in which the ball is moved on the display screen changes, the positional relationship among the buttons changes according to the direction in which the ball is moved on the display screen. Can be assigned to not.

  In the above embodiment, the baseball game has been described as an embodiment, but the present invention may be applied to a soccer game or a shooting game, and is not limited to the above embodiment.

  Note that step S24 corresponds to the camera angle changing means described in claims, steps S20, S28, S34 correspond to the marker display means, and steps S45, S51, S53 correspond to the switching means.
