Hi,well, in 2d fitghing game (dragon ball), when the player does a "special power" i use animated gif. And they have transparent parts.
I want to the collision detection something like this:
(this will for example when goku launchs a kamehameh)
if (the color of the player1.posX+player1.width is not transparent)
if (player1.posx+player1.width >= player2.posX )
collide = true
