Instance Method

removeObstacles(_:)

Removes the specified obstacle from the graph.

Declaration

func removeObstacles(_ obstacles: [GKPolygonObstacle])

Parameters

obstacles

An array of obstacle objects to be removed from the graph.

Discussion

Adding or removing obstacles does not update the graph. The GKMeshGraph class adds, removes, and arranges nodes to describe the navigable areas around obstacles only when you call the triangulate() method. Typically, you add or remove several obstacles, then call the triangulate() method to update the graph.
