Instance Method

connectUsingObstacles(node:)

Adds the specified node to the graph, connecting it to its nearest neighbors without creating connections that pass through obstacles or their buffer regions.

Declaration

func connectUsingObstacles(node: NodeType)

Parameters

node

A graph node object containing 2D coordinate information.

Discussion

The GKMeshGraph class maintains a network of nodes that describes the navigable areas around its collection of obstacles. Adding a new node to the graph connects it to these nodes, such that the resulting network can be used to find paths around the obstacles to the position of the new node. GameplayKit adds new connections only if those connections do not represent a path through any obstacles (or through the buffer region around them, as specified by the bufferRadius property.)
