Question

I have an instance variable, like so:

PathFinder finder;

(this is using Kevin Glass’ A* tutorial, so the PathFinder class is in the same file, link here: http://cokeandcode.com/index.html?page=tutorials/tilemap2)

Anyways, when I do

finder = new AStarPathFinder(currentMap, 1000, true);

I get a Exception in thread “”AWT-EventQueue-0″ java.lang.ExceptionInInitializerError”.

currentMap is an instance of my Map class, and yes it is initialized. 1000 represents the maximum tile distance that will be searched, and the boolean represents diagonal movement true/false. Oh well I’ll just throw the constructor at you:

public AStarPathFinder(TileBasedMap map, int maxSearchDistance, boolean allowDiagMovement) {
    this(map, maxSearchDistance, allowDiagMovement, new ClosestHeuristic());
}

I know it has something to do with static initializers, but I’m not too sure what else. Oh, and I tried to initialize an instance of the same AStarPathFinder class in another class, and I got the same result.

Answer 1

I read the full stack trace, and the error was that the parameters for a method in the parent class and in the child class wasn’t the same, somehow the IDE just didn’t make any notification.
