KinematicCharacterBody.GetSlideCollisions() Method
Returns all contact pairs resolved during the last post-physics step. Normals are oriented away from the other body toward this character. Useful for surface material detection, landing sounds, and wall-jump queries. The list is cleared and repopulated every tick — do not hold a reference across frames.
