retrieveNamedObstacleByIndex

Used for iterating through fixed obstacles.

void retrieveNamedObstacleByIndex(tSigned32 index, iAgent*& agent, const char*& id) const;

	index		Enumerating index.
	agent		This returns a pointer to a newly constructed agent encapsulating the fixed obstacle.
	id		This will be set to a pointer to a C string containing the obstacle's content ID. The string pointed to may be invalidated if changes are subsequently made to the set of fixed obstacles stored.

Retrieving a fixed obstacle does not remove the fixed obstacle from the set of fixed obstacles stored with a mesh.
