Well I've been thinking and It came to mind...

How did the old NES Duckhunt Game work

You had to hook up the gun controller thing and aim it at the ducks on the screen. But my question is , If the TV is just the same old TV how did it know where the gun was being aimed at on the screen?

I wants to knows , it would be interesting to find out how. 

IIRC, it worked by shooting a laser beam at the TV, and (from what i learnt in Pysics), the beam would bounce back to the gun, and it would figure out what was going on.

Hmm... interesting question, I just wanna know what made you think about it

I wonder if it has to be a reflective suface like glass, or if you hooked the NES up to a projector and played if it would work if you played it off a wall.

I don't think so. Because (from what I learnt from Physhics) the beam will bounce back to the gun at the perfect angle type type thing. So no matter where you aimed the gun it still would pick the laser up the same.

How does the Nintendo Duck Hunt work?

A: The Nintendo Zapper Gun, also remembered fondly as the Duck Hunt gun, isn't really a gun, it's a photoelectric sensor that detects the light given off by the TV. When you pull the trigger on the gun, the Nintendo system tells the TV to momentarily replace the ducks with white rectangles. If you go back and play the game again, you'll notice that the screen flashes momentarily when you pull the trigger. If the gun happened to be pointing at a duck at that specific moment, the sensor in the gun transmits to the NES that it had a white rectangle in its field of view, which the game registers as a hit. In the oldest models of the gun, you could simply point the gun at a light bulb and make a direct hit every time. Later versions of the gun corrected the problem by having the screen flash completely black, then with white triangles, then black again. The gun was programmed to recognize "black, white, black" as a direct hit. This system used by the Zapper, which is known as a light gun, was also used in arcade games.

Does this mean it would work with projectors or Plasma/LCD screens?

prolly.




it worked with a light bulb, didn't it?

I'm not sure about projector screens, because those aren't direct light sources, but reflect the light of the projector. But plasma/LCD screens should work, I think...

Hahaha thats way cool !!

I always wanted to know how that worked
