Instance Method


Adds new obstacles to the graph.


func addObstacles(_ obstacles: [GKPolygonObstacle])



An array of obstacle objects to be added to the graph.


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.
