Pixel Test Help
« on: May 16, 2011, 12:12:55 am »
Can somebody clear up exactly how pixel-test( works? For the Helicopter game I have been working on I just threw a bunch of them together, and I achieved a sort of half working collision detection.

I am using an 8x16 helicopter sprite, if that is important.  And the bricks I am colliding with are 3 pixels wide by 8 pixels tall.

Pixel-test(x,y) returns 1 if the pixel at (x,y) is solid and 0 otherwise.

And remember it's X,Y (instead of Y,X like in BASIC).
