The gun sees the light output from the screen ( almost always only sees blue ) and calculates exactly where you have it pointed by the start of the flash and when the gun sees the scan line light up, the console can tell what part of the screen should be being painted at that point. The screen will flash a full black field followed instantly by a white field in most cases, some cases only blue, this way every part of every line will be lit up, and the gun will see the scanning with an LDR, tells the console, and you hit the screen in the spot youre aiming. The black field is apparently to reduce the chances you can cheat by aiming at a fluro light in the case of some guns, and some games... NES Duck Hunt is a perfect example... It will even work on a plasma display in some circumstances, but it is the only one that will, and not every time either.
The reason these light guns dont and cant work on digital type displays is cause they refresh all at once, there is no scanning. The scanning gives the console something to count before it sees the flash. Without that, the console will always think youre pointed off screen. |
Thanks for the great explanation!
