I reprogrammed my collision and wall sliding from the ground up and I want to share it with you. You can port this to any language you like or just watch me code to see how it works. I will also be recreating common video game glitches to show why they happen.

Thank you so much for subscribing and watching! I hope we can hang out again sometime.
