My 2D collision code does not work as expected. How do I fix it?
I have a simple 2D game with a tile-based map. I am new to game development, I followed the LazyFoo tutorials on SDL.
The tiles are in a bmp file, but each tile inside it corresponds to an internal ...

Collision detection with multiple polygons simultaneously
I've written a collision system which detects/resolves collisions between a rectangular player and a convex polygon world using the Separating Axis Theorem. This scheme works fine when the player is ...

How can I find the collision response between a moving sphere and cube?
I'm implementing my own algorithm for sphere and cube collision response. So far I'm able to only test if both of them overlap.
My problem is: A cube is rotating around its axes i.e x and z axes. And ...

Understanding the use of MTV for an elastic collision response
So, I'm trying to simulate polygon physics, both linear and angular.
To calculate the MTV is easy in SAT (Minimum Translation Vector), and to use it to adjust position is also easy:
