Weird Array Bug

Hey guys,

I’m having this really obnoxious bug in a 2d array. Getting array data only works when searching with a positive increment.

Find Grid Code:


	public static Grid getGrid(float x, float y) {
		Grid r = null;
		try {
			r = channels[(int) x][(int) y];
		} catch (ArrayIndexOutOfBoundsException e) {
			r = new Grid();
		}
		return r;
	}

Here is where the problem is:


	public void findNeighbors() {
		if (!found) {
			north = Game.getGrid((int) position.x / 10, (int) (position.y / 10) - 1);// not
																					// working
			east = Game.getGrid((int) position.x / 10 + 1, (int) position.y / 10);// working
			west = Game.getGrid((int)( position.x / 10) - 1, (int) position.y / 10);// not
																					// working
			south = Game.getGrid((int) position.x / 10, (int) position.y / 10 + 1);// working
			found = true;
		}
	}

The program is only working when getting the east and south tiles.

I just don’t understand why this could be happening.
