I’m sorry but I’m still working on this game, so I can’t give the source code for this exact project. But if you want you can use an older version I made open source a while ago: Retro Racing 64. It’s not really the same, the physics are messed up, it has only 1 track, the tracks are built differently, there are no bots, etc. But it could be useful as a starting point. At least the camera code is mostly the same. And for the physics, the logic is actually really simple, I based the code on this article: Simple 2D car steering physics in games
