Greetings fellow gamers, has anybody found an always working way of implementing fast 2D collission detection? Let me describe the problem. If I have two moving circles and I want to detect if they collide, it''s no problem if the circles are moving very slowly, but if one of the circles (maybe representing a projectile) moves so fast, that it could "leap" over the other circle in one frame, collission detection would sometimes fail. I thought about computing a line representing the projectiles position and destination, and then doing a collission detection with the line, and the other circle. That would work, but is somewhat expensive in CPU cicles. Anybody got some valuable insights on this issue?
