Separation ray shape resource for 3D physics. 3D separation ray shape to be added as a [i]direct[/i] child of a [PhysicsBody3D] or [Area3D] using a [CollisionShape3D] node. A ray is not really a collision body; instead, it tries to separate itself from whatever is touching its far endpoint. It's often useful for characters. [b]Performance:[/b] Being a primitive collision shape, [SeparationRayShape3D] is fast to check collisions against. The ray's length. If [code]false[/code] (default), the shape always separates and returns a normal along its own direction. If [code]true[/code], the shape can return the correct normal and separate in any direction, allowing sliding motion on slopes.
