At 0, it has a function of instructing the direction in which the fielder moves for catching a ball, and instructing the base to which the catched ball is thrown by the A button 42, B button 43, X button 44, and Y button 45, respectively.

FIG. 3 shows a flowchart of one embodiment of the ball catching processing routine executed by the CPU 22 of the apparatus of the present invention. In this processing routine, a screen is displayed at a camera angle at which a camera placed behind a fielder (object) attempting to catch a ball in the home base direction (or the center direction) in accordance with the hitting position. The camera angle for shooting toward the center is when the catcher catches the catcher goro, when it is not determined which fielder will catch the ball immediately after hitting, and when the fielder other than the catcher catches the ball Is a camera angle for shooting in the direction of the home plate.

In the figure, in step S10, it is determined from the elevation angle of the hit ball (ball: target) whether the hit ball is fly or goro. If the hit ball is a ball, the process proceeds to step S12, where the CPU 22 selects a fielder who can reach the hit ball the fastest and catches the ball based on the direction and speed of the hit ball, the position of each fielder, and the running speed. An arrow-shaped catching marker is displayed above the head of the fielder. This catching marker indicates the direction of the fielder's movement. 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, step S
Proceeding to 20, the CPU 22 calculates the drop 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. This drop point marker is translucent blue and has a predetermined height (= h1) larger than the height of the fielder.
In addition, it has a cylindrical shape with a diameter enough to surround the fielder, and is displayed in a state of standing at the drop point on the ground surface. Further, in step S22, from the position and the running speed of each fielder, a fielder who can reach the falling point and can catch the ball is selected, and an arrow-shaped ball catching marker is displayed above the head of the selected fielder.
The ball catching marker indicates the direction of movement of the fielder and the direction of catching the ball.

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 step S24, the camera angle is sequentially changed according to the position of the fly hitting ball and the position of the fielder so that the camera placed behind the fielder can see the hitting ball, and screen display is performed. Here, the fielder 50, the hit ball 52, and the ball catching marker 54 are displayed on the screen immediately after the hit shown in FIG. 4, but the dropping point marker is not displayed yet because the fielder 50 is far from the dropping point. The subsequent screen shown in FIG. 5 shows the fielder 50,
A hit ball 52, a ball 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. If not, the fly hit ball cannot be caught. Therefore, the process proceeds to step S14 to perform a ball catching process. If it can be reached, the process proceeds to step S28, where the falling point marker is changed from translucent blue to translucent green. The screen shown in FIG.
0, a hit ball 52, a ball catching marker 54, and a falling point marker 58 that has changed to a translucent green are displayed. Thereafter, the process proceeds to step S30, in which the CPU 22 automatically rotates the fielder until the fielder faces the falling direction of the fly hit ball. At this time, how much the fielder rotates depends on the direction in which the fly hit ball falls and the direction in which the fielder reaches the drop point marker.

Next, in step S32, by the time the fly hit ball falls to the position where the fielder catches the ball, it is determined whether or not the fielder has been able to rotate in the direction in which the fly hit ball falls to an angle at which he can catch the ball. Determine. If the fielder has rotated to the angle at which he can catch the ball, the height of the drop point marker is set to h in step S34.
Deform to about 1/2 and change to translucent yellow. Thereafter, in step S36, when the hit ball falls to the height position where the fielder catches the ball, the ball is captured. The screen shown in FIG. 7 includes a fielder 50, a hit ball 52, a catching marker 54, and a height of 1 /
A drop point marker 60 that has become translucent yellow in 2 is displayed. Thereafter, the processing routine is terminated and the processing proceeds to the throwing processing. On the other hand, if the fielder could not rotate to the angle at which he could catch the ball, he could not catch the fly hit ball,
The process proceeds to step S14 to perform a ball catching process.

As described above, since the marker indicating the drop point where the ball reaches according to the change of the camera angle is displayed, the drop point can be displayed clearly even if the camera angle of the three-dimensional display is changed. By displaying the marker in a three-dimensional manner, the target position can be displayed clearly even if the camera angle of the three-dimensional display is changed. Furthermore, since the display mode 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 marker display mode.

By the way, as described above, in the ball catching processing routine, a screen is displayed at a camera angle taken by a camera placed behind a fielder who intends to catch a ball in accordance with the ball hitting position. When catching a ball, it is a camera angle for shooting toward the center, and when a fielder other than the catcher catches a ball, it is a camera angle for shooting toward the home plate.

When the A button 42 is fixed to the second base, the B button 43 is fixed to the third base, the X button 44 is fixed to the first base, and the Y button 45 is fixed to the home base, fielders other than the catcher catch the ball. If it is a camera angle shooting toward the home base direction, the player will not be confused, but if the catcher catches catcher goro, it is a camera angle shooting toward the center, Since the screen and the button position of the input operation pad 36 are reversed left and right, the player may be confused and erroneously operate.
