示例1: findPath
//This is the method that will do A*. It returns a vector of locations to follow
public LinkedList<Vector3> findPath(Vector3 start, Vector3 end)
{
LinkedList<Vector3> result = new LinkedList<Vector3> ();
Node startNode = currentGraph.getNodeByLocation ((int)start.y, (int)start.x);
startNode.rawCost = 0.0f;
queue = new PriorityQueue (startNode);
while (!queue.isEmpty()) {
//The A* magic happens here
Node minNode = queue.pop ();
//if this is our ending node, stop pathfinding and form our full path on the graph
if (minNode == currentGraph.getNodeByLocation ((int) end.y, (int) end.x)) {
//Here we form the path depending
Node currentNode = minNode;
while (currentNode != null) {
result.AddFirst(new Vector3(currentNode.widthPos, currentNode.heightPos));
currentNode = currentNode.parent;
}
resetGraph();
return result;
}
//else, we need to update our priority queue, etc.
else {
float currentRaw = minNode.rawCost;
