Godot Version
4.2.2
Question
Hey all, i’m new to the forums,
i’m trying to make a mario kart like control scheme, this is my first time trying godot and i’m having a bit of a problem.
my idea is to allign the kart to the surface i’ts on, using it’s sphere collision to find the point it’s touching. (in the future i will separate the road, wall, and offroad collision meshes, so it will be able to go different speeds or bounce if it touches those ),
but everithing i’ve tried is glitchy.
this is my code for now, dont mind drift and jump, thats all WIP,
altho any help is appreciated!
and everything that comes out of this is free for anyone to use, i just want to make a meme game for me and my friends
i’d even upload the project if i could
