	/// and helps with the winding order of the vertices as well as automatically updating the obstacle when moved.

	/// Extend this class to create custom RVO obstacles.

	/// Deprecated: This component is deprecated. Local avoidance colliders never worked particularly well and the performance was poor. Modify the graphs instead so that pathfinding takes obstacles into account.
