Approach (of :class:`Motion`)
=============================

.. class:: Approach

	Defined in Approach.sc.

	
	A motion class that causes the :class:`Actor` to move approach a target until within a certain distance, and then stop.
	This Motion class ignores the room obstacles. In SCI1.1, if path-finding is required, one would generally use the :class:`PolyPath` class instead.
