Ok so my roomate has a old nitendo he brought in. And we have been sitting down wondering how it works. I looked online and cannt find the answer so does anyone know why the lightgun works?
 
I'm pretty sure it works by reflecting the signal off the tv screen, and it comes back to the gun, which senses the position of where it fired and makes that your target zone. Also, light guns won't work with projection televisions because of this. All's I know is my friend and I used to put a magnifying glass in front of the zapper and get a flawless score in duck hunt :)
 
what it does is when you pull the trigger,the tv flashes a white block around the target for like 5-10frames,while the sensor trys to find the white singnal. if found it registers as a hit

they had on G4 some guy turned a super9 airsoft rifle into a nes light gun
 
ok then how do the ones for PS2 and in the arcades and stuff work? Cuz those screen dont flash....

Normally they do, it is sometimes hidden in the muzzle flash. Or it happens in one frame so 99% of people don't notice it. Like a single frame of pornography in a children's movie. Fancy arcade games like Silent Scope may even track the gun through the scope or know the cordinates the gun is pointed through sensors.

Another trick is to have a pattern that flashes on the character faster then the eye can track. The gun sees that pattern, decides if it is a friend or foe and if the pattern is in a reasonable range for the gun to hit.

Nintendo tried a different method that for the SNES that would tell colors apart from the background, The problem was certain colors were harder to hit because of the way color works. I think it was red was the problem color. At least, I think that is the way it worked.
 
That's funny, I was having this very conversation the other night with two guys at a party. I was wondering if we could hook duck hunt up to the movie screen at my old work... but I didn't think so.
 
I can't tell you how it works, but I can confirm with you that the NES Zapper (light gun? WTF is a light gun?) does not work with a projection screen, I've tried. Must need the TV somehow.

If anyone cares, I'll report back on whether or not the SNES Super Scope works on the projector as well. As soon as I can find Battle Clash at a flea market. :D
 
Just from what i've read a few years ago.

Lightguns work because it is completely in sync with your TV's refresh rate. The lightgun senses when the specific pixel it is pointed at is updated and by referencing it with the refresh, it knows exactly what part of the screen it is pointed at.

If this still holds true (Hey, i was just a kid then, i can't verify that now!), then lightguns wouldn't work with LCD screens, projectors included.

modern day lightguns work this way,but not the nintendo light gun remember this would be quite a bit of processing for a lil what 3mhz cpu?lol
 
i remember the super scope having a little senser you plugged into the controller port or something, and then you had to calibrate it.
 
Actually, on the NES lightgun.


The screen flashes white, and the shoot-able targets flash a black square.
