Member Function Documentation

override void GetNodes ( GraphNodeDelegateCancelable  del)
virtual

Calls a delegate with all nodes in the graph.

This is the primary way of "looping" through all nodes in a graph.

This function should not change anything in the graph structure.

myGraph.GetNodes ((node) => {
Debug.Log ("I found a node at position " + (Vector3)node.Position);
return true;
});

Implements NavGraph.

override void ScanInternal ( OnScanStatus  statusCallback)
virtual

Scans the graph, called from AstarPath.ScanLoop.

Override this function to implement custom scanning logic The statusCallback may be optionally called to show progress info in the editor

Implements NavGraph.
