Is there any way to make a sprite collide with a background color?

Lets say you load an bakgound map that scrolls and want a sprite to collide with green borders, how do I do that? Is it posible?

Thanks!

Yeah, it can be done. It's not hard, but it's not the best way either.

You'd use the POINT(X,Y) command to return the color value of a pixel on the background. If the return value is equal to that green color then you'd trigger your collision routine.

Weird, I thought I posted some code showing you how to do this...Oh well, here goes.

Try this...Ofcourse you'll need to set the x,y coords and you'll also need to feed the RGB command the color. You'll also want a more signifigant set of insturctions other than the text one I've used.

IF POINT(x,y)=RGB(0,0,0)
TEXT 0,0,"Collision!"
ENDIF
