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.
