Another Sprite vs Sprite Collision Detection Issue 1.1.4


Recommended Posts

I have encountered a problem with collision detection if I set the velocity of a sprite so it will move towards another sprite when it is already touching that sprite.  This problem is encountered when the user holds a key to walk up to an obstacle, then attempts to walk through it.


Any suggestions?
