How did Duck Hunt for Nintendo work?

347 views

It came out nearly 40 years ago. They didn’t put out “real” motion sensing games until 2006. Feels like I’m missing something.

Fun fact, and maybe an additional question, the game doesn’t work on projection or LCD screens, only old CRTs. If it’s just a light censor, why wouldn’t it work on all?

Think not of the gun shooting at the screen, but the screen shooting at the gun.

The gun has a light sensor that can only see a small part of the screen, the game flashes a black screen with a white box where the duck is at the moment you hit the trigger, if the gun “sees” the white square, you were aiming in the right place and you get the hit.

Fun fact. They only work on old crt TV. They relied on the fact that there was a constant frame rate. They don’t work on new tvs

When you press the trigger, for a moment the screen goes black with a white rectangle where the target is. If the gun detects light, you’ve hit the target.

If there are two targets, there will be a white rectangle on the first target, then 1/60th of a second later – on the second target. Depending on the exact moment the gun detected light, it can tell which target you’ve hit.

To prevent cheating, there’s always a brief moment before the white rectangles appear where the entire screen is black. That way the gun can tell you’re not pointing at a lamp, because it first sees one frame of darkness, then one frame of light.
