Player slides on slopes

[Malcolmnixon]

If the player stands on a slope they will slide down hill. This used to be fixable by setting stop_on_slope=true in the KinematicBody.move_and_slide call, however that has been broken since godot 3.2 so an alternative implementation will be needed.

A common approach is to detect when the player is on the ground and "skew" the gravity in the direction of the ground surface normal.

Testing in demo projects shows the approach of applying gravity "normal" to the surface works quite well.
