Better slopes in AABB collision systems (opens in new tab)

Earlier this year I on how to implement slopes in AABB collision resolution using bump.lua. The resulting system worked, but was a bit hard to use in-game and had a few issues, so I wouldn’t consider it a viable solution. The main issue with the old approach was the use of the cross collision response. It allowed the object to move through the slope as if it wasn’t there at all, and then the update loop corrected the y position after the fact. This alone makes writing code the game a lot more...
