Abstract

PURPOSE: To change the progress of a game by varying the destruction force of a gun (firearms) by storing the number of times of for a player to operate an operating member as a count value and changing attack power corresponding to this count value. CONSTITUTION: When a program is started, first of all, a CPU circuit 7 clears a pumping counter and judges later whether the player performs pumping or not. In this case, pumping, means the sliding operation of a pumping member provided at the gun. Next, it is judged whether hopping is performed more than twice or not and it is judged whether the player turns on a trigger switch (manipulator 2) or not. Continuous y, the XY position (coordinate) of enemy objects 1-N (N is an integer) is detected and it is judged whether an emitted beam hits any one of enemy objects 1-N or not. Afterwards, the number of times of pumping is investigated from a pumping counter and corresponding to this number of times, the degrees of destruction force are made different.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gun shooting game machine in which a projectile collides with an enemy aircraft object to destroy the enemy aircraft object.

[0002]

2. Description of the Related Art In this type of conventional gun shooting game machine, the destructive power of the gun is fixed, and it is possible to attack a highly durable enemy for a long time (multiple times). I was able to finally destroy it.

[0003]

When the destructive power of the gun is fixed, there is no attack method other than continuous attack for a long time (more than once) against the enemy with durability. However, there was a drawback that the game progress became monotonous.

The present invention has been made in view of the above problems, and it is an object of the present invention to change the destructive force of a gun (gun) to change the progress of the game.

[0005]

To achieve this object, a gun shooting game machine of the present invention comprises an operating member operated by a player and a counter for storing the number of times the player operates the operating member as a count value. , And a power changing means for changing the attack power according to the count value of the counter.

[0006]

In the gun shooting game machine having the above structure, the attack power is changed according to the count value of the counter, that is, the number of times the player operates the operation member. As a variable, the progress of the game can be changed.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block connection diagram showing an embodiment of a gun shooting game machine according to the present invention.

In FIG. 1, the video game machine comprises a coin-related device 1, an operating device 2, a monitor 3, and a speaker 5 with a TV game device 4 as a center. The coin-related device 1 communicates with the TV game device 4 (the input / output control circuit 6) and manages the number of coins to be inserted and the payout. The operation device 2 is a joystick,
Devices such as buttons and switches operated by the player. The monitor 3 converts the image output signal of the TV game device 4 into a visible image and displays it. Speaker 5 is a TV
The audio output signal of the game device 4 (sound system circuit 16) is converted into an audible sound and output.

The TV game device 4 includes an input / output control circuit 6,
It is composed of a CPU circuit 7, a video control circuit 11, a screen memory 14, a sound system circuit 16, and the like. The input / output control circuit 6 communicates with the coin-related device 1 mutually and sends information such as the number of coins to be inserted and payout to the CP.
It is transmitted to the U circuit 7. In addition, a state in which the player operates a joystick, a button, a switch and the like (operating device 2) is detected and transmitted to the CPU circuit 7. CPU circuit 7
The transmission and reception of signals to and from are performed via the system bus 8.
The work memory 9 is used as a work area of the CPU circuit 7. The program of the CPU circuit 7 is stored in the program memory 10.

When the CPU circuit 7 outputs an image,
Image data is written to the screen memory 14 via the video control circuit 11 and the video bus 13. Monitor 3
Reads the image data written in the screen memory 14, converts it into a visible image, and displays it. The player is
The game proceeds while watching the visible image on the monitor 3.

When the CPU circuit 7 outputs a voice,
The audio data is output to the sound system circuit 16 via the dual port RAM 15. The sound system circuit 16 performs audio signal processing, generates an analog audio output signal, and outputs the analog audio output signal to the speaker 5. The speaker 5 outputs the audio output signal of the sound system circuit 16 as an audible sound. The player advances the game while listening to the sound output from the speaker 5.

FIG. 2 is a flow chart showing a subroutine of the program of the CPU circuit 7, which is called from the main routine and started. When the program starts, first clear the pumping counter (reset)
To do. In step S2, it is determined whether the player has performed pumping. Pumping here means that in FIG.
As shown in (a) and (b), it means that the pumping member 21a provided at the bottom of the gun 21 is slid in the direction of the arrow. The gun 21 is provided as a part of the operating device 2. Further, as the pumping, in addition to the rotating operation, other operations such as an operation of pushing a button or an operation of depressing a pedal may be performed.

When it is determined in step S2 that the player is not pumping, the process proceeds to step S6. When it is determined that the player has performed pumping, the process proceeds to step S3 and it is determined whether or not pumping is performed twice or more. If it is determined that the number is two or more, the pumping count is set to 2 in step S4 and then step S4 is performed.
Go to 6. When it is determined that the number is smaller than two, the pumping count is set to 1 in step S5 and the process proceeds to step S6. That is, the pumping counter is 0-2
It is set to a value up to, and pumping more than three times is wasted. The pumping counter can be set to a value of 3 or more.

Before moving from step S4 or step S5 to step S6, a main routine (not shown)
Then, the game process (display of enemy objects, etc.) is performed and the process proceeds to step S6. In step S6, it is determined whether or not the player has turned on the trigger switch (operating device 2). When it is determined that the trigger switch is off, the process returns to step S1. When it is determined that the trigger switch is on, the beam or the bullet is fired and then the process proceeds to step S7. In step S7, the XY positions (coordinates) of the enemy objects 1 to N (N is an integer) are detected. In step S8, it is determined whether or not the beam or bullet fired in step S6 hits one of the enemy objects 1 to N. When not hitting, it returns to step S1.
If it hits, the process proceeds to step S9.

In step S9, the number of times of pumping is checked from the pumping counter. When the number of times of pumping is 0, the enemy objects 1 to N that hit the object are destroyed with a weak destructive force (power). When the number of times of pumping is one, the enemy objects 1 to N that hit the object are destroyed with a medium destructive force (power). Furthermore, when the number of times of pumping is 2, the enemy objects 1 to N that hit the object are destroyed with a strong destructive force (power). The degree of destructive power (power) may be the degree of damage.

As described above, since the degree of destructive power (degree of damage) is varied depending on the number of times of pumping, it is necessary for the player to proceed with the game while considering the attack method. Can make a difference. In other words, the game progresses while always considering whether or not there is enough time to perform pumping and whether or not a strong destructive force is required, and thus it is possible to bring various changes to the progress of the game. Become.

Although the case where the gun 21 is used has been described in the embodiment, the present invention can be applied to the power of the bullet fired from the turret.

[0019]

As described above, according to the gun shooting game machine of the present invention, the count value of the counter, that is,
Since the attack power is changed according to the number of times the player operates the operation member, it is possible to change the destructive power of the gun (gun) to change the progress of the game.
