示例1: AddNode

        if ( Physics.Raycast(neighborPoint, rayDirection, out hitInfo, Mathf.Infinity, layerMask) )
        {
            if (hitInfo.transform.tag == "Ground")

                GraphNode newNode = new GraphNode(mNumOfNodes, hitInfo.point); // make a new node for this point
                GraphEdge newEdge = new GraphEdge(currentNode.GetIndex(), newNode.GetIndex()); // creat a new edge

                int index = 0;

                while ( !nodeFound && index <= mNumOfNodes )
                {
                    //Debug.Log (index + " out of " + NavigationGraph.Length + " thinks there's only" + mNumOfNodes);

                    ++index;
                }

                if ( !nodeFound ) // if we have not found this node before, add it

                else
                {
                    newEdge.SetToIndex(index-1);
                }

                // If the raycast hit then we will always want to add the edge, since we want edges
                // in both directions and there won't ever be duplicates.

                // check if there is a clear path to add an edge
                Vector3 heightOffset = Vector3.zero;
        #if USE_XZ
                heightOffset = new Vector3(0, 0.5f, 0);
        #else
                heightOffset = new Vector3(0, 0, -0.5f);
        #endif // USE_XZ
                if ( !Physics.Linecast(currentNode.GetPosition() + heightOffset, newNode.GetPosition() + heightOffset, out hitInfo, layerMask) )
                {
                    Edges.Add(newEdge);
                    currentNode.AddEdge(newEdge);
                }
            }
        }
    }
