I want to know how to check for collisions efficiently in case where the player's box is larger than a map tile.

On the left is my usual case where I make 8 checks against every surrounding tile, but with the right one it would be much more inefficient.

(picture of two cases: on the left is the simple case, on the right is the one I need help with) http://i.stack.imgur.com/k7q0l.png

How should I handle the right case?

I'm working on a 2D game in which I would like to do collision detection between a moving circle and some kind of static curves (maybe Bezier curves). Currently my game features only straight lines as the static geometry and I'm doing the collision detection by calculating the distance from the circle… >>> More
