Hey guys, I'm making a street fighter type game with sprite sheets and such, but my collision detection for my punches and kicks is off because of how wide the sprite sheet image is. Could I possibly make a collision detection with color, placing the color on top of the fist in the sprite sheet so whenever the color on the fist collides with the other player the health goes down?

Sure. alternatively if you can treat your sprites as polygons. if the polygons overlap then it's a collision. or if it's a straight punch, check if the tip of the fist is inside the opponent's polygon.

Actual implementation depends on what language/framework you're using.

Stick to the topic. What framework are you using?

Collision detection is always fun. I know I am late to the game, but if you are still messing around with this I would like to expand on what carteblanche was talking about.You mentioned sprites, so I am assuming your "world" is a 2D plane. In this case, you can construct a "bounding box", which would be a polygon, around each sprite. Once this is achieved, using a bit of computational geometry you can determine at which point either of the polygons intersect each other. At the point of intersection would be your collision detection.
