Thanks! Wallrunning was really tough will smart shapes I'm not gonna lie. I think we "borrowed" the code from an open-source sonic fangame that had wallrunning, but that got tough to modify as the project went on. I believe it used a raycast system to check if the floor was getting closer or moving further away in front & behind the player and adjusted the rotation based on that. It probably used the normal vectors to do some math too or something like that. If you're still struggling with it, I can try to find that sonic project, but I can't promise anything haha
Thank you so much! The sonic project would be great, but you've already given me more than enough :D Was this the project you were talking about? https://github.com/Sslaxx/Godot_Sonic_Engine/tree/master
