Abstract

PURPOSE:To provide the electronic game device being more similar to an actual play sensation. CONSTITUTION:In the case coordinates of a ball matched with coordinates of a racket of a user or a computer (S31, YES), an incident angle of the ball is derived from a speed of the ball (S37). Also, from the previous value and the present value of a moving speed of the racket of the user, or the previous time and the present value of a moving speed of the racket of the computer, whether the ball is received, while moving the racket, or the racket is moved after the racket is stopped and the ball is received is decided (S38). Subsequently, from a ball reflection table TB1, a repulsion angle and a speed variation of the ball conforming to a receiving condition are derived (S39). Moreover, from the repulsion angle and a speed classification of its ball, an X component and a Y component of the speed of the ball are calculated, and furthermore new coordinates of the ball are derived (S40).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic game machine.

[0002]

2. Description of the Related Art Conventionally, an electronic game in which a racket and balls of a plurality of players are displayed on a liquid crystal display device, a CRT or the like, and by moving the rackets according to the movement of the balls, a game similar to tennis can be enjoyed. The device is realized.

In this game apparatus, the computer of the game apparatus takes charge of one player, the user takes charge of the other player, and one player serves to start the game. For example, if the computer is the server and the user is the receiver, when the served ball travels diagonally and hits the left and right walls, it reflects and travels toward the receiver. When the user (receiver) operates the cursor key to move the racket to the position of the ball, the ball is reflected by the racket and advances to the opponent's court. At this time,
If the racket does not reach the ball position, a receive miss will occur. Similarly, the server moves the racket by hitting the ball by moving the racket according to the movement of the ball hit by the receiver, and these operations are repeated to continue the game.

[0004]

By the way, although there are some conventional game devices that can perform a cutting operation by operating a racket, the conventional game device does not perform a cutting operation when the ball hits the racket. The change of the ball was decided depending on whether or not, and the movement of the ball was uniform.

In actual play, if the player quickly moves to the point where the ball falls and hits it aiming, he can make a smash or volley at a fast speed in the desired direction. If you do, the smash and volley will not be decided well. The conventional game device cannot realize such an actual playing feeling.

An object of the present invention is to change the reflection angle and speed of the ball according to the movement of the player with respect to the ball,
It is an object of the present invention to provide a game device capable of realizing a play closer to an actual play feeling.

[0007]

In a game device in which a plurality of players alternately hit a ball with a racket, the game device of the present invention has a display means for displaying the rackets and the balls of the plurality of players, and a racket of the player. A moving means for moving the display position and a control means for changing at least the reflection angle and speed of the ball according to the state of the racket when the racket is moved by the moving means to receive the ball.

The control means changes the reflection angle and velocity of the ball depending on whether the racket is moving when the ball is received, or when the ball is received while the racket is stopped and then the racket is moved.

[0009]

According to the present invention, for example, when receiving a ball hit by an opponent player, the ball is received while moving the racket, or the ball is moved depending on whether the racket is temporarily stopped and received and then the racket is moved. The reflection angle and speed of are changed.

As a result, when the player quickly moves to the planned passage point of the ball and hits the ball (when the racket is stopped and received and then the racket is moved), the player smashes at a fast speed in the intended direction. It is possible to determine a ballet and a ballet, and it is possible to realize an actual sense of play that a smash or volley is not well determined when a player moves late and receives while moving.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is an external front view of an electronic desk calculator 1 with a game function according to the present invention, and FIG. 1B is an enlarged view of its display section.

In addition to the above, the liquid crystal display unit 3 displays "COMP" and "YO" indicating whether the server is on the computer side or the user side.
U ”,“ HiLEVEL ”that is lit when the game mode is high level, and“ GAMEOVER ”that is lit at the end of the game, and the designated calculation type is“ ÷, ×, −, + ” A display body that indicates which of the two is provided is provided.

Next, FIG. 2 is a circuit block diagram of the calculator 1 of the embodiment. The oscillator 11 generates a clock signal that serves as a reference for the operation of the control unit 12. The controller 12 is the ROM 13
It is a central processing unit that executes arithmetic processing or a tennis game in accordance with a control program stored in, and the data input from the key input unit 2, the arithmetic result or the racket position in the game mode, the racket moving speed,
The position of the ball and the like are stored in the RAM 14, and the display driver 15 is controlled to display the calculation result, the game situation, and the like on the display unit 3. In addition, the speaker 16 is driven to sound an alarm sound when the game ends.

FIG. 3 shows a ball reflection table TB1 which determines the reflection angle and reflection speed of the ball in the tennis game stored in the ROM 13, a timer interruption speed of ball movement processing (described later) which determines the movement speed of the ball, CO that determines the moving speed of the racket on the computer side
It is a figure which shows the timer interruption speed table TB2 which shows the timer interruption speed of MP movement processing.

The ball reflection table TB1 stores the ball reflection angle and velocity corresponding to the ball incident angle and the receiving condition. For example, when the angle of incidence of the ball is 30 ° to the left, the racket is stopped at the receive position, the ball is received, and then the racket is moved to the right. The incident velocity and the constant velocity are stored as the velocity of the ball. Similarly, after the racket is stopped and received, the racket is moved leftward in correspondence with the receive condition that the ball reflection angle is 45 ° left, 45 °,
High speed is stored as the speed of the ball. In addition, in order to meet the condition that the racket is moved to the right and the ball is received, the reflection angle of the ball is set to the right 30
°, the low speed is stored as the speed of the ball, and in response to the condition of receiving the ball while moving the racket to the left, the reflection angle of the ball is set to the right 45
The incident velocity and the constant velocity are stored as the velocity of the ball.

Below, for other incident angles and receive conditions, the reflection angle and velocity of the ball corresponding to each condition are stored. The angle of incidence of the ball indicates the angle that the ball makes with the surface of the racket, and the left and right directions mean the directions viewed from the player side.

On the ball reflection table TB1, when the racket is stopped and the ball is moved and then the racket is moved, and when the racket is moved and received, the incident angle of the ball is different in each case. Different ball reflection angles and velocities are stored depending on whether the racket is moved forward or backward. Therefore, this ball reflection table TB
By determining the reflection angle and speed of the ball with reference to 1, it is possible to hit back a fast ball according to the operation of the racket of the user or the computer, or hit the ball by changing the reflection angle of the ball.

Further, in the timer interrupt table TB2 showing the timer interrupt speed of the ball moving speed and the timer interrupt speed of the COMP moving processing, each timer interrupt speed is stored in correspondence with the change of the speed of the ball before and after the receive. Has been done.

For example, the ball reflection table T described above.
Corresponding to the case where the ball speed is increased from low speed based on B1, medium speed is stored as the interrupt speed of the ball moving process, and medium speed is stored as the interrupt speed of the COMP moving process. High speed is stored as the interrupt speed of the ball moving process and medium speed is stored as the interrupt speed of the COMP moving process corresponding to the case where the ball speed is increased from medium speed.

Further, in response to the case where the ball speed is reduced from medium speed to low speed, the timer interrupt speed is set to low speed,
Low speed is stored as the computer interrupt speed. Therefore, for example, when the ball speed is medium speed or high speed, when the racket is stopped and the ball is received and then the racket is moved in the direction opposite to the incident angle of the ball, the reflection table TB1 of the ball reflects the ball. High speed is set as the speed, and further, from the above-mentioned timer interrupt speed table TB2, the high speed is set as the timer interrupt speed of the ball moving process and the medium speed is set as the timer interrupt speed of the COMP moving process. As a result, the moving speed of the ball becomes faster than the moving speed of the racket on the computer side, so that the computer cannot receive the ball and the smash of the user is successful.

That is, by using the above-mentioned table, the reflection angle and speed of the ball change according to the receiving condition, and the moving speed of the ball and the moving speed of the racket on the computer side also change in various ways. A game similar to playing tennis can be realized. These operations will be described in detail later.

Next, FIG. 4 is a diagram showing the configuration of the registers of the RAM 14. The RAM 14 stores registers A, B, and C for storing numerical values input from the key input unit 2, calculation results, and the like.
And X indicating the position of the user's racket on the display unit 3.
A register N0 that stores the coordinates and the Y coordinate, a register N1 that stores the X coordinate and the Y coordinate indicating the position of the racket on the computer side, a register N2 that stores the X coordinate and the Y coordinate indicating the position of the ball, and a user Registers L ₀ and L ₁ that store the previous and current values of the racket movement speeds X and Y, and registers L ₂ and L that store the previous and current values of the racket movement speeds X and Y on the computer side. ₃ , a register L ₄ for storing the ball velocities X and Y, a register M ₀ for storing the interrupt speed of the ball moving process, and a register M ₁ for storing the interrupt speed of the racket moving process of the computer. There is.

Next, the operation of the embodiment having the above configuration will be described with reference to the flow charts of FIGS. 5 to 8 and the diagrams showing the rasive state of FIGS. 9 and 10. The case where the computer (control unit 12) and the user compete with each other will be described below.

FIG. 5 is a flow chart showing the overall processing contents in the game mode. Step S1 in FIG.
If any interrupt timer counts up in step S2, it is determined in step S2 whether the timer interrupt is a timer interrupt for activating the key input and movement processing on the YOU side for moving the position of the racket of the user. If it is a timer interruption of the key input and movement processing on the YOU side, the key input and movement processing on the YOU side at step S3 is executed.

FIG. 6 is a flow chart for explaining the key input and movement processing on the YOU side. First, in step S11 of FIG. 6, the present value of the moving speed of the racket of the user stored in the register L ₁ of the RAM 14 is stored in the register L _0.
Set as the previous value of the racket moving speed. next,
In step S12, it is determined whether or not the cursor key input operation has been performed. If the cursor key input operation is not performed at this time, the process proceeds to step S15, and X = 0 and Y = 0 are set as the current moving speed.

On the other hand, if the cursor key input operation is being performed in the determination in step S12, step S13
Then, the moving speed of the racket is determined in accordance with the operation of the cursor key, and the moving speed is set as the current moving speeds X and Y in the register L ₁ . In this process, for example, when the cursor is operated once, a low speed is set as the moving speed, and when the cursor is continuously pressed, the moving speed is gradually increased.

Next, in step S14, the coordinates (X, Y) of the new racket are calculated based on the current moving speed set in the register L ₁ , and the calculation result is stored in the register N0 for storing the racket position of the user. Set to and move the racket.

Returning to FIG. 5, when the YOU key input and movement processing is completed, or when the determination in step S2 is NO, the process proceeds to step S4, and it is determined whether the generated timer interrupt is the timer interruption of the COMP movement processing.
If the result of this determination is a timer interruption of the COMP moving process, the process proceeds to step S5 and the COMP moving process is executed.

Here, the contents of the COMP moving process will be described with reference to the flowchart of FIG. Step S of FIG.
At 21, the coordinate of the racket on the computer side of the register N1 is moved by one in the direction of the ball in the Y-axis direction. The current moving speed of the racket of the register L ₃ of the computer sets as the previous moving speed of the register L ₂ in step S22.

Furthermore, by selecting one of the random numbers -1,0,1 as a component in the Y-axis direction of the moving velocity of the racquet at step S23 to set the value as the current moving speed of the register L _3. As a result, a random value is set as the moving speed of the racket on the computer side, so that the game is further changed.

Returning to FIG. 5, when the COMP moving process is completed, or when the determination in step S4 is NO,
The ball (BALL) movement process of step S7 is executed. FIG. 8 is a flowchart showing the contents of this ball moving process. First, in step S31 of FIG. 8, it is determined whether the coordinates of the ball in the register N2 match the coordinates of the user's racket in the register N0 or the coordinates of the computer's racket in the register N1.

If the coordinates do not match, step S3
2 and the coordinate of the ball in the register N2 is X = 0 or X
= 18, that is, whether the ball has reached the end line of the court due to an error in the racket operation by the user or the computer. When the ball has reached the end line in the determination in step S32, step S33
Then, the game is ended by determining the win or loss of the user and the computer.

When the determination in step S32 is NO, the process proceeds to step S34 and it is determined whether the coordinate of the ball in the register N2 is Y = 0 or Y = 6, that is, whether the ball has reached the side line. When the coordinates of the ball reach the side line, the process proceeds to step S35, where the sign of the Y direction component of the speed of the ball in the register L ₄ is inverted,
The inverted value is stored in the register L ₄ as the ball velocity. This causes the ball to be reflected off the sides of the court.

When the determination in step S34 is NO, the process proceeds to step S36, the coordinate of the next ball is calculated from the coordinate of the ball in the register N2 and the velocity of the ball in the register L ₄ , and the calculation result is stored in the register N2.

On the other hand, if the coordinates of the ball coincide with the racket position of the user or the computer in the determination of step S31, the process proceeds to step S37, where the ball incident angle is determined from the ball velocities X and Y stored in the register L _4. Ask for.

In the next step S38, the registers L ₀ and L ₁
The receiving method is determined from the previous value and the current value of the moving speed of the racket of the user, or the previous value and the current value of the moving speed of the racket of the computer in the registers L ₂ and L ₃ . In this process, by comparing the previous value and the current value of the racket moving speed, whether the ball was received while moving the racket, or whether the racket was once stopped and the ball was received and then the racket was moved. Is judging. Specifically, when the previous moving speed in the Y-axis direction is "0", it is determined that the racket is temporarily stopped, the ball is received, and then the racket is moved left and right, and the previous movement in the Y-axis direction is performed. When the moving speed is not "0", it is judged that the ball is received while moving the racket.

When the receiving method is determined in the process of step S38, the reflection angle and velocity of the ball are determined by referring to the reflection table of the ball of FIG. 3 based on the result. In step S40, the X component and the Y component of the ball speed are calculated from the ball reflection angle and the high speed, medium speed, and low speed types obtained from the ball reflection table of FIG. 3, and the calculated values are stored in the register of the RAM 14. Store in L ₄ .
Further, the coordinate of the next ball is calculated from the ball speed and the current coordinate, and the calculation result is stored in the register N2.

In step S41, it is checked whether or not the speed of the ball has changed before and after receiving. If the speed has changed, the ball moving process and the COMP moving process are referred to by referring to the timer interrupt speed table TB2 in FIG. Set the interrupt speed of.

Next, FIGS. 9 and 10 show a forward direction (left direction in this case) with respect to the incident direction of the ball when the ball is struck on the court of the user at an angle of 45 ° to the right and at a medium speed. It is a figure explaining the reflection angle and speed of a ball at the time of moving a racket in the opposite direction (right direction in this case) when a racket is moved to.

FIG. 9A shows the ball reflection angle and the ball reflection angle when the racket is temporarily stopped and the ball is received, and then the racket is moved in the forward direction (left direction) with respect to the incident direction of the ball. It is a figure which shows speed.

In this case, the receiving condition is "incident angle right 4
5 °, after moving, it moves to the left ”. Therefore, from the ball reflection table TB1 in FIG. 3, a ball reflection angle of 30 ° to the left and a constant velocity (in this case, medium velocity) are obtained. By the ball moving process described above, the ball is hit back at a medium speed in the direction of 30 ° to the left centering on the racket position of the user.

The velocity of the ball reflected at the middle speed in the left 30 ° direction is X = 1, Y = -2 (X direction, Y shown in FIG. 9A).
When the velocity component in the direction is positive), the coordinate advances by one in the X-axis direction and the coordinate advances by two in the Y-axis direction. At this time, since the moving speed of the racket of the computer is medium and the coordinates of the racket can be moved only one by one, the computer cannot catch up with the ball, resulting in a receive miss.

Further, as shown in FIG. 9B, when the ball is received while the racket is moved to the left, the receiving condition is "incident angle 45 ° rightward, moving left". From the ball reflection table TB1 of, the ball reflection angle is 45 ° to the left and the ball speed is low. Therefore, the ball is hit back at a low speed in the left 45 ° direction centering on the racket position of the user by the above-described ball moving process.

The velocity of the ball reflected at a low speed in the left 45 ° direction is X = 1 and Y = -1, and while the coordinate advances by one in the X axis direction, the coordinate advances by one in the Y axis direction. . Further, in this case, since the speed of the ball is reduced from the middle speed to the low speed, the interrupt speed of the ball moving process is low from the timer interrupt speed table TB2 of FIG.
Since the interrupt speed of the OMP moving process becomes low and the moving speed of the ball becomes the same as the moving speed of the racket of the computer, the computer catches up with the ball and the attack of the user fails.

FIG. 10A shows the reflection of the ball when the racket is stopped and the ball is received, and then the racket is moved in the direction opposite to the incident angle of the ball (in this case, the right direction). It is a figure which shows an angle and a speed.

In this case, the receiving condition is "incident angle right 4
5 °, it moves to the right after stopping, ”so that from the ball reflection table TB1 in FIG. 3, a ball reflection angle of 60 ° to the right and a high ball velocity can be obtained. The ball is hit back at a high speed in the direction of 60 ° to the right around the racket position.

The speed of the ball reflected at a high speed in the direction of 60 ° to the right is X = 2 and Y = 1, and while the coordinate advances by one in the Y-axis direction, the coordinate advances by two in the X-axis direction. further,
In this case, since the speed of the ball changes from medium speed to high speed, the interrupt speed of the ball moving process is high and the interrupt speed of the COMP moving process is medium speed from the timer interrupt speed table TB2 of FIG. Therefore, the computer cannot catch up with the ball, resulting in a receive miss.

As shown in FIG. 3B, when the ball is received while the racket is moved to the right, the receiving condition is "incident angle right 45 °, moving right". From the ball reflection table TB1 of, a ball reflection angle of 60 ° to the right and a ball velocity of constant velocity (in this case, medium velocity) are obtained. Therefore, by the ball moving process described above, the right 6
The ball is hit back in the 0 ° direction at medium speed.

In this case, since the speed of the ball does not change before and after receiving, the interrupt speed of the ball moving process, C
The interruption speed of the OMP movement processing becomes medium speed, the computer can catch up with the ball, and the attack of the user fails.

In the above-described embodiment, when the racket is stopped, the ball is received, and then the racket is moved, a fast ball is hit back and smash, volley, etc. succeed, and the ball is moved while moving the racket. When receiving, a weak ball is hit back to prevent smashing, volleying, etc. from succeeding, so that a playing sensation similar to that of actual tennis play is obtained, and a more interesting game device can be realized.

The present invention is not limited to the above-mentioned electronic desk electronic computer, but can be applied to an electronic notebook, a personal computer, a game-dedicated machine, or the like. Further, the game is not limited to the match with the computer, and two or more people can play the game as players.

[0056]

According to the present invention, for example, when the racket is stopped and the ball is received and then the racket is moved, the ball is hit back at a high speed, and when the racket is received while moving, the speed is slower than that. Since the ball is hit back, it is possible to realize a play similar to smash and ballet in an actual tennis game, and provide a more enjoyable game.
