By pressing any of the saddle-shaped buttons 204a to 204d in the saddle-shaped button group 204, the basket to be sent is directly designated. For example, even if the game screen is switched between the catcher-side screen and the outfield-side screen by pressing the third base button 204c, it is an instruction to send a ball to the third base. Intuitive instructions are possible without being confused by the display screen. A pitching is instructed by the decision button 206 on the left side. The bat type switch 210 is not used.
[0031]
At the time of hitting, as shown in FIG. 4A, a grasshopper cursor indicating the hitting position is moved using the saddle type button group 204 as a direction key. The first button 204a is a right button, the second button 204b is an up button, the third button 204c is a left button, and the main button 204d is a down button. The batting switch 210 indicates the strength of the hitting.
[0032]
The hitting strength is indicated by the rotation angle of the bat 211 of the butt switch 210. If the rotation angle of the bat 211 is within about 90 degrees, it becomes a bunt, but the strength of the bunt can be finely adjusted by changing the rotation angle within this range. When the rotation angle of the bat 211 is larger than about 90 degrees, a swing is made. The swing strength can be adjusted by changing the rotation angle. When it is 180 degrees or more, full swinging is performed vigorously, and when it is about 90 to 150 degrees, meat batting such as sinking is performed.
[0033]
Stealing is instructed by the left determination button 206, and time is instructed by the left determination button 208.
At the time of scoring, as shown in FIG. 4B, a scissors designation is made when advancing or returning using the scissor button group 204. By pressing any of the scissors buttons 204a to 204d in the scissors button group 204, the scissors are directly designated. Advancing is instructed by the decision button 206 on the left side, and a return is designated by the decision button 208 on the right side. For example, pressing the third base button 204c and the determination button 206 on the left side gives an instruction to advance to the third base. Even if the game screen is switched between the catcher-side screen and the outfield-side screen, an intuitive instruction is possible without being confused by the display screen. The bat type switch 210 is not used.
[0034]
Next, details of the operation method of the bat-type switch 210 will be described with reference to FIG.
As described above, the bat type switch 210 is used by the attacking player when hitting. By operating the bat-type switch 210, the batter performs various operations. When the attacking player moves the bat switch in the player introduction scene or the two-part scene, the bat of the player in the screen moves in conjunction with the movement, and each player performs a swing motion. The game may be changed by changing the swing motion for each player. The swing motion common to each player will be described.
[0035]
As shown in FIG. 5A, when the bat-type switch 210 is not moved at all, the grasshopper in the screen moves back to hold the bat in front of the body and takes a relaxed posture.
As shown in FIG. 5B, when the bat 211 of the bat-type switch 210 starts to be pulled clockwise, for example, when the bat 211 passes a point of 75 degrees, the movement of the grasshopper bat in the screen and the bat 211 The movements of A light swinging motion is performed until the angle of the bat 211 reaches 180 degrees.
[0036]
Thereafter, as shown in FIG. 5C, when the bat 211 of the bat-type switch 210 is moved between 75 degrees and 179 degrees, the grasshopper in the screen is interlocked with the movement of the bat-type switch 210. Do a light swing. When the bat 211 is stopped, the grasshopper in the screen grips the bat at that position.
When the player releases his / her hand from the bat 211 while the bat 211 of the bat-type switch 210 is pulled, the grasshopper in the screen performs a batting operation, but performs various batting operations according to the operation at that time.
[0037]
For example, as shown in FIG. 5D, when the bat 211 of the bat type switch 210 is pulled to 180 degrees and the hand is released, the grasshopper in the screen performs a full swing. Further, as shown in FIG. 5E, when the bat 211 of the bat-type switch 210 is moved away from the position between 75 degrees and 179 degrees, the grasshopper in the screen performs the operation of swinging the bat from the swing motion. Do. The striking strength can be changed by changing the angular position of the bat 211.
[0038]
As shown in FIG. 5 (f), when the bat 211 of the bat-type switch 210 is stopped for a certain period of time between 75 degrees and 105 degrees, for example, 30 frames (1 second) or more of the game screen, Then the grasshopper in the screen bunts. In this state, when the bat 211 is pulled more than 105 degrees, a swing motion is performed, and when the bat 211 is released, a strike is performed from the swing motion.
[0039]
In the present embodiment, the initial speed of the bat 211 of the bat-type switch 210 is detected, and as shown in FIG. 5G, a striking action is performed to swing the bat when the initial speed is a certain value or more. However, if the start of the batting operation is determined based on only the initial speed, the swing operation may be performed beyond a certain initial speed even if the bat 211 of the bat-type switch 210 is slightly loosened. Therefore, in this embodiment, as shown in FIG. 5 (h), even if the initial speed of the bat 211 is equal to or higher than a certain value, the position of 90 degrees is within a certain time, for example, 6 frames (0.2 seconds). If not, switch to half swing operation.
[0040]
In this way, when the bat 211 of the bat-type switch 210 is stopped halfway, a half-swing operation is performed, and an instruction suitable for the player's operational feeling can be given, and the operational feeling of the bat-type switch 210 is improved. can do.
Next, an image display method in the game device according to the present embodiment will be described with reference to FIGS.
[0041]
FIG. 6 shows a game screen 300 at the time of pitching and hitting. The game screen 300 is divided into right and left, the attack side uses the left screen 310, and the defense side uses the right screen 320.
In the attacking side screen 310 on the left side, a small hitting position screen 311 for indicating the hitting position is provided. A strike zone 313 is displayed in the hitting position screen 311. In addition, in the attack side screen 310, a game character to be operated by the attacking player, that is, a batter is displayed.
[0042]
Similarly, a small pitching position screen 321 for instructing the pitching position is provided in the defensive screen 320 on the right side. A strike zone 323 is also displayed in the defensive screen 320. Further, in the defensive side screen 320, a game character to be operated by the defensive player, that is, a pitcher is displayed.
A radar screen 330 for displaying a copy of the entire baseball field and the progress of the baseball game is provided between the attack side screen 310 and the defense side screen 320.
[0043]
The defensive player confirms the appearance of the game character (pitcher) in the defensive screen 320 in FIG. 6 and looks at the pitching position screen 321 by using the saddle type button group 204 as shown in FIG. Move the pitching position freely up, down, left and right. When the pitching position is moved, the pitcher cursor 322 in the pitching position screen 321 moves. The player designates a target position while looking at the strike zone 323 and the pitcher cursor 322.
[0044]
The attacking player confirms the appearance of the game character (batter) in the attacking side screen 310 of FIG. 6 and looks at the hitting position screen 311, as shown in FIG. Move the striking position freely up, down, left and right. When the hit position is moved, the batter cursor 312 in the hit position screen 311 moves. The player rotates by the striking strength aimed at the bat 211 of the bat-type switch 210 and operates the saddle-shaped button group 204 to specify the target position while looking at the strike zone 313 and the batter cursor 312.
[0045]
Note that when the player's offense and defense are changed, the attack side screen 310 and the defense side screen 320 are interchanged, making it easier for the player to operate.
In this way, when the attacking player and the defensive player input the hitting position and the pitching position using one screen, as shown in FIG. The player can concentrate on his / her input operation, and it becomes difficult to see the operation content of the other party, which makes it possible to realize the fun of bargaining as a baseball game.
[0046]
FIG. 7 shows a game screen 300 at the time of pitching. When the defensive player presses the enter button 206, the pitcher enters a pitching motion, and the attacking screen 310 and the defensive screen 320 are unified as shown in FIG. In the unified game screen 300, the strike zone 303 is unified. The radar screen 330 moves to the lower right.
FIG. 8 shows a game screen 300 at the time of hitting. When the player on the batting side releases the bat 211 of the bat type switch 210, the batting is performed at the batting position aimed at with the aimed batting strength. In FIG. 8, the afterimage of the bat can be seen is an effect for giving a sense of reality.
[0047]
Next, the processing procedure of pitching and hitting play from the setting at the time of pitching and hitting will be described according to the flowcharts of FIGS. 9 and 10 with reference to the game screens of FIGS.
FIG. 9 is a flowchart showing the processing procedure of the pitcher player.
The processing of the pitcher side player is started on the pitching / hitting division screen of FIG. 6 divided into two on the pitching side and the batting side. First, it is determined whether or not a time is requested from the pitcher player (step S10). If time is required, pitcher change processing is performed (step S11).
[0048]
If the time is not requested, it is determined whether or not the pitcher-side player has instructed to throw the check ball (step S12). If an instruction to throw the check ball is given, the screen moves to a check ball screen (not shown), and processing such as determination of the check ball is performed (step S13).
When the check ball instruction is not performed, it is determined whether or not the waiting time for the pitching player instruction has ended (step S14). When the waiting time is over, it is determined whether or not the batter player is performing a swing motion on the batter (step S15). When the swinging motion is being performed, after a predetermined time has elapsed (step S16), the process returns to step S15.
[0049]
If the waiting time has not ended, it is determined whether or not the pitcher-side player has pressed the pitching button 206, that is, whether or not the pitching operation has been started (step S17). When the pitch button 206 is not pressed, the operation state of the saddle type button group 204 as the direction key operated by the pitcher player is detected, and the pitcher cursor 322 indicating the position to throw is moved based on the operation state. Then, the pitching position is displayed in the pitching position screen 321 of FIG. 6 (step S18).
[0050]
If the pitcher-side player presses the pitching button 206, the process proceeds to step S15, and if the batter is not performing a swinging motion (step S15), the pitching motion is started (step S19).
Until the pitching operation is started, that is, from step S10 to step S18, the pitching / hitting division screen of FIG. 6 divided into two on the pitching side and the hitting side is continuously used. When the pitching operation is started in step S19, the pitching / hitting division screen of FIG. 6 is switched to the pitching screen of FIG.
[0051]
The pitcher-side player can select a ball type using the saddle type button group 204 after the pitcher starts the pitching motion (step S19) and before the ball leaves the hand (step S21) (step S20). . By pressing any one or combination of the saddle-shaped buttons 204a to 204d in the saddle-shaped button group 204, a ball type such as a straight ball, a curve, a slider, a sinker, and a fork is selected.
[0052]
After the ball leaves the pitcher's hand, the pitcher's player can bend the trajectory of the thrown ball by operating the progressive button group 204 (steps S22 and S23). After step S21, it is determined whether any of the saddle-shaped buttons 204a to 204d in the normal button group 204 has been pressed (step S22). When the saddle type buttons 204a to 204d are pressed, the ball movement and display processing is performed (step S24) so as to bend the locus of the ball in the input direction (step S23). If the saddle-shaped buttons 204a to 204d are not pressed, the ball movement and display processing is performed without bending the trajectory of the ball (step S24).
[0053]
FIG. 10 is a flowchart showing the processing procedure of the batter player.
The batter-side player process is started on the pitching / hitting division screen of FIG. 6 divided into two on the pitching side and the batting side. First, it is determined whether or not time is requested from the batter player (step S30). If the time is requested, a substitution process is performed (step S31).
[0054]
If the time is not requested, it is determined whether or not the batter player has operated the bat switch 211 (step S32). When the bat-type switch 211 is operated, the batter starts a batting stance motion (step S33). Subsequently, it is detected whether or not the butt switch 211 is off (step S34), and if it is off, the process returns to step S30.
[0055]
If it is determined in step S32 that the bat-type switch 211 is not operated, or if it is determined in step S34 that the bat-type switch 211 is not turned off, a pitcher pitching motion is subsequently started by the pitcher-side player. Whether or not (step S35). When the pitching motion is not started by the pitcher player, the batter indicating the position to hit based on the operation state of the saddle type button group 204 as the direction key operated by the batter player is detected. The cursor 312 is moved and the hit position is displayed in the hit position screen 311 of FIG. 6 (step S36). When the pitcher side player presses the pitch button 206 to start pitching, the process proceeds to step S37.
[0056]
Until the pitching operation is started, that is, from step S30 to step S36, the pitching / hitting division screen of FIG. 6 divided into two on the pitching side and the hitting side is continuously used. When the pitching operation is started, the pitching / hitting division screen of FIG. 6 is switched to the pitching screen of FIG. 7 that is not divided into two.
In step S37, processing for automatically tracking the batter cursor 312 to the pitcher cursor 322 is started. The speed of tracking is determined according to the batter's ability. Further, the batter player can control the tracking direction and the tracking speed of the batter cursor 312 by operating the saddle type button group 204 even after the pitcher starts the pitching motion and leaves the hand. After step S37, it is determined whether any of the saddle-shaped buttons 204a to 204d in the normal button group 204 has been pressed (step S38). When the saddle type buttons 204a to 204d are pressed, the batter cursor 312 is moved in the input direction to track the pitcher cursor 322.
[0057]
Subsequently, it is determined whether or not the bat type switch 210 of the batter side player is turned off (step S40). When the bat-type switch 210 is off, the batting operation by the bat-type switch 210 has been completed, so a swing operation is performed as shown in FIG. (Step S42). If the butt switch 210 is not turned off in step S40, the process returns to step S38, and the processes in steps S38 to S40 are repeated.
Note that the processing after the hit determination in step S42 is processed using a program that complies with the rules of actual baseball. For example, if it is determined that the batter has swung, the ball is returned to the pitcher and the processing shown in the flowcharts of FIGS. 9 and 10 is performed again. In addition, for example, if the batter swings and swings, there is a display that alternates with the next batter, and the processing shown in the flowcharts of FIGS. 9 and 10 is performed again. When the defensive / running process described later results in 3 outs, the player's offense and defense is changed, and the processes shown in the flowcharts of FIGS. 9 and 10 are performed.
[0058]
Next, the display on the radar screen 330 will be described with reference to FIGS. 8 and 11 to 13.
When the batter hits and the ball flies to the outside field, the game screen 300 moves from the point of view from the attack side shown in FIG. 8 following the ball as shown in FIG. Immediately before catching the ball, the screen changes from the back side of the fielder to the defensive point of view as shown in FIGS. At this time, the radar screen 330 is also enlarged / reduced according to the position of the sphere with reference to the home base. When the hit distance of the hit ball is short, the fielder may be caught from the front as it is without wrapping behind the fielder.
[0059]
In FIG. 8, since the game progress is performed only in the infield, the radar screen 330 displays only the infield in an enlarged manner. Therefore, when the hit ball flies to the outfield, the viewpoint rises to include the hit ball that flies, and the screen is gradually reduced. In FIG. 11, a reduced view is displayed compared to FIG. 8 from a viewpoint that includes a part of the infield and the outfield, and further, a reduced display is displayed compared to FIG. 11 from a viewpoint that includes all of the infield and the outfield. That is, on the radar screen 330, the viewpoint rises from FIG. 8 to FIG. 11 and FIG. 12, and is reduced and displayed by zooming.
