computer screen

The gun games are called so because it makes use of a gun-shaped peripheral that makes the functions of command (in the case of computers, usually by replacing the mouse, which acts as a pointer). These games began to appear in the 80s, thanks to the development of light sensors. The operation was simple: The objectives were moving across the screen, and the player pointed the gun at them. At the time of pressing the trigger, the gun delivered a beam of light. If you reached this goal, the game recognized that the player had been on target. The most modern games worked opposite way: The objectives issued a signal indicating a location, and the gun that had a sensor to pull the trigger if it was indicated by pointing to one at the time of the shooting. Recently, there are devices for the recognition of position (such as command of the Nintendo console, Wii), which detect the direction of the pointing control / gun, and function similarly to a computer mouse (with a pointer on the screen). As the shooters on rails, the movement tends to be limited in such games. Some outstanding games in this genre are: Virtua Cop, Time Crisis sagas and House of the Dead, and Duck Hunt, from the NES.
