Abstract

PURPOSE:To accurately decide a winning/losing state, to remove a flicker to occur on a display screen, and to make a player concentrate on a game by measuring the direction of a barrel by a potentiometer at shooting time, calculating the address of a screen RAM corresponding to a gunshot point on the screen, comparing the calculated address with the address of a target, and judging the winning/losing state. CONSTITUTION:The subject device is composed so that a movable base 14 can rotate around the center shaft of a light beam gun 4, and a potentiometer 18 for measuring the azimuth of the light beam gun 4 can rotate through a first gear 16 when the azimuth of the light beam gun 4 changes and so that a potentiometer 19 for measuring the elevation of the light beam gun 4 can rotate through a second gear 17 to rotate together with an arm 8 when the elevation of the light beam gun 4 changes. The direction of the light beam gun 42 is to be grasped by the outputs of the potentiometer 18 for measuring the azimuth and the potentiometer 19 for measuring the elevation. Further, when the player takes aim at the target and pulls a trigger 4b of the light beam gun 4, an oscillating shaft connected to a plunger 13 touches a chassis, an impact occurs in the light beam gun 4, and the actual feeling of the shooting is given to the player.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an improvement in a ray gun shooting game device.

[Conventional technology]

A light gun shooting game device is known in which a predetermined video signal is formed according to a predetermined program, a desired image including a target is displayed on a display device, and a light gun is used to shoot the target in the image. .

In a conventionally known ray gun shooting game device, the ray gun is supported by a gun holding device so that the elevation angle and azimuth angle of the ray gun can be freely changed, and a lens and a light receiving element are provided in the gun barrel. When the person aims at a target in the image including the target displayed on the display device and pulls the trigger of the ray gun, the video signal changes to a monochromatic constant level signal for one frame of the display device, and during that period, the light receiving element When it detects the image of a spot scanning the screen, it learns the impact point from the corresponding address and determines whether it is a hit or miss by comparing this with the address of the target that exists on the normal game screen. Ta.

For this reason, conventionally known ray gun shooting game devices change the screen to a monochrome screen for one frame each time the trigger of the ray gun is pulled, so the screen tends to flicker, especially when the game is played by multiple players. There was a problem in that this became noticeable and the player's interest in the game was lost.

[Problem that the invention seeks to solve]

The present invention has been made to solve the above-mentioned problems, and its purpose is to display only one frame of the screen in a single color when determining success or failure in a light gun shooting game device. To provide a new ray gun shooting game device which allows players to immerse themselves in the game by making it possible to accurately determine hits and misses without screen scratches, eliminating flickering occurring on a display screen.

[Means for solving problems]

Therefore, the above purpose is to measure the direction of the gun barrel with a potentiometer when shooting, calculate the address in the screen RAM that corresponds to the point of impact on the screen, and compare this with the address of the target to determine if it is a hit or miss. This is accomplished by a ray gun shooting game device configured as such.

(Function) As described above, in the present invention, when the trigger of the ray gun is pulled, the position of the target in one frame of the screen and the elevation angle and azimuth of the ray gun directed toward the screen are determined. Hits and misses are determined by comparing the position of the gun muzzle in one frame of the screen calculated based on the angle, so unlike conventional light gun shooting game devices, there is no need to worry each time you pull the trigger of the light gun. It is possible to eliminate the flickering on the display screen, and further increase the player's interest in the game.

The ray gun shooting game device 1 according to the present invention includes a video display screen 3 and two ray guns 4.4 facing the video display screen 3 in a housing 2.

Further, the arm 8 that supports the ray gun 4 is attached to a movable base 14.
The second gear 17 is also configured to be able to rotate around a central axis perpendicular to the movable base 14, and can be tilted within a certain angle around a rotational central axis 20 of the second gear 17.

Therefore, the ray gun 4 can change the elevation angle and azimuth angle to desired angles, but once the elevation angle and azimuth angle reach a certain angle, further movement is restricted by the action of a movable range stopper case (not shown). It is configured to be

Note that when the azimuth of the light gun 4 changes, the movable head I4 rotates around its central axis, the potentiometer 18 for measuring the azimuth angle rotates via the first gear 16, and the azimuth angle of the light gun 4 changes.
When the elevation angle of the arm 8 is changed, a potentiometer 19 for measuring the elevation angle is connected via a second gear 17 that rotates together with the arm 8.

Then, aim at the target and press the trigger 4b of the ray gun 4.
When pulled, a current is applied to the solenoid coil 10, and the solenoid coil 10 moves the plunger 13 back and forth in the direction of the gun barrel against the elastic force of the return spring 12, and is thereby connected to the plunger 13. A vibration shaft (not shown) hits the chassis, which generates an impact on the light gun 4, giving the player the feeling of shooting.

Next, FIG. 5 will be explained.

The 110 boat 21 receives input signals from a well-known toll storage device, game start switch, etc., encodes them and sends them to the CPU 23, etc., and also receives signals from the CPU 23 and inputs them to each of the input/output devices mentioned above. control the functions of

The PROM 22 stores programs, object patterns, etc. necessary for the game, and these data are supplied to the CPU 23 as necessary.

The CPU 23 responds to the input from the I10 boat 21 and operates the entire audio circuit 27, screen RAM 30, and judgment circuit 31.
The screen RAM 30 stores one frame worth of image data for displaying the background, target, etc. on the video screen.

The sound generation circuit 27 responds to signals from the CPU 23 and generates a predetermined sound signal according to the progress of the game, and outputs a predetermined sound signal to the speaker 2.

When a hit signal is issued, image data showing the destroyed target is written into the screen RAM 30 in response to a signal from the CPU 23, and the image of the destroyed target is displayed on the video display screen 3.

〔Effect of the invention〕

Since the present invention is constructed as described above, when the trigger of the ray gun is pulled according to the present invention, the address of the target in one frame of the screen and the elevation angle of the ray gun directed toward the screen are determined. Hit or miss is determined by comparing the address of the impact point on the screen calculated based on the azimuth and the azimuth.
This eliminates the flicker on the display screen that occurs each time the trigger of a ray gun is pulled, as in conventional devices, and allows the player to become more immersed in the game.
