+===== landingAngle =====
+Set landing angle in degrees. Used to check during collision response if an actor is landing on ground. This is done by comparing the impact normal of the ground against the project-to-ground direction. If this angle is small enough the actor is considered to land on ground instead of flying against a wall or scratching the ground in an upwards motion.
