Simple Physics for Game Programming: Circular Collisions & Movement (Part 1 of 2)
How can I program Mario to jump on an enemy or a car to bounce off of another car? This tutorial will show you how, using the simple physics simulations to handle collision detection (if an object has collided with another) and the response (how it should bounce).
Could've been better
Raphael was very patient and helpful. Wasn't able to address all of my issues/questions (not that I really expected that), but was certainly able to help get me pointed in the right direction. Thanks! Would not hesitate to use his help again.
