We all have played video games in our childhood or now in home or arcade. Shooting is main subject in most of the video games and the old and famous shooting gun had added more fun to the shooting job in games, isn’t it? Ever wondered how this little and not so complicated gun works and knows where to shoot? From my childhood till now I always wondered how, but now I have an answer.
First thing first, this gun is sure a complicated electronic hardware and uses two techniques to analyse data of the game in which one is easy and one is hard in structure. When we are saying uncomplicated, it is for using this accessory and as we thought about it. Inside this video game gun there is an electronic circuit connected to a light detector which is located in the shooting barrel of the gun. When we press the tiger to shot something on TV screen the photo detector located in the gun receives a light signal from the TV screen so the game machine knows the desired target the gun is shooting at and it is correct or not. Televisions screen alight objects in horizontal and vertical retrace signals received from the screen driver, so the game computer knows the position exactly as it is of any object on the screen. So its simple, the game data and images are going to TV input from the game machine and so game machine knows what is where. When we shoot a target from the gun connected with a wire to the game console the signals reflected from the TV screen traces our move that where we have shooted and it is correct or not. Something which is complicated in this all is a different technique used by some manufacturers to locate the target by this gun. The game console in the method first deal the whole screen as whole black then renders the whole screen black, when we can only see the ongoing game videos and noise the game computer is actually calculating the data received from photo detector. It is calculated by the amount of time between the moments in which the black screen turns into white and so it’s calculate in which direction of the Television screen the gun is pointing. This same technique is used in joystick too.
The most used way to locate a target by the gun is the non complicated way. This also renders image and the targeted objects. By synchronizing the images with the signals received through the gun, the game console measures data with the help of photo detector and luminosity. If the luminosity is high, the gun is pointed towards the target and so the target will be hit. Of course when the luminosity is low the target will be declared as no hit. So next time you play with the shooting gun in a video game or if you have grown up may be kids in your home may wonder about this simple accessory, you sure know the answer now!
