Node that represents collision shape data in 2D space. Editor facility for creating and editing collision shapes in 2D space. You can use this node to represent all sorts of collision shapes, for example, add this to an [Area2D] to give it a detection shape, or add it to a [PhysicsBody2D] to give create solid object. [b]IMPORTANT[/b]: this is an Editor-only helper to create shapes, use [method get_shape] to get the actual shape. A disabled collision shape has no effect in the world. Sets whether this collision shape should only detect collision on one side (top or bottom). The actual shape owned by this collision shape.
