How to climb any wall (in a video game) Godot 3d Tutorial
144Even though I use the Godot Game Engine this can literally be reproduced in any game engine, I think the logic was explained well enough but there is always some leap in logic I might have made đŸ˜…. This movement system is really similar to a spiderman wall climbing or xenomorph crawling system and can be used to make really cool games.
2D Vector Math hack:

Basically, if your vector is (1,2) - so an upward arrow, you flip the x and y, and you are done so the new vector is (2,1) which is a rightward arrow, or perpendicular to the upward arrow (1,2). People say you can flip the x spot but it'll just give you the arrow in the other direction.
