Base class for all 2D Shapes. Base class for all 2D Shapes. All 2D shape types inherit from this. http://docs.godotengine.org/en/3.0/learning/features/physics/physics_introduction.html Return whether this shape is colliding with another. This method needs the transformation matrix for this shape ([code]local_xform[/code]), the shape to check collisions with ([code]with_shape[/code]), and the transformation matrix of that shape ([code]shape_xform[/code]). Return a list of the points where this shape touches another. If there are no collisions, the list is empty. This method needs the transformation matrix for this shape ([code]local_xform[/code]), the shape to check collisions with ([code]with_shape[/code]), and the transformation matrix of that shape ([code]shape_xform[/code]). Return whether this shape would collide with another, if a given movement was applied. This method needs the transformation matrix for this shape ([code]local_xform[/code]), the movement to test on this shape ([code]local_motion[/code]), the shape to check collisions with ([code]with_shape[/code]), the transformation matrix of that shape ([code]shape_xform[/code]), and the movement to test onto the other object ([code]shape_motion[/code]). Return a list of the points where this shape would touch another, if a given movement was applied. If there are no collisions, the list is empty. This method needs the transformation matrix for this shape ([code]local_xform[/code]), the movement to test on this shape ([code]local_motion[/code]), the shape to check collisions with ([code]with_shape[/code]), the transformation matrix of that shape ([code]shape_xform[/code]), and the movement to test onto the other object ([code]shape_motion[/code]).
