I don't know if it has something to do with OpenGL or it's just Java in general but..
distance = (int) Math.sqrt(((ent.getX() - x) ^ 2) + ((ent.getY() - y) ^ 2));
I sometimes get NaN from that.
Although, if I move it around like this..
distance = (int) Math.sqrt(((x - ent.getX()) ^ 2) + ((y - ent.getY()) ^ 2));
Instances where it would NaN would return normal numbers, but on the otherhand the instances where it returns a normal number is now NaN.
What did I do wrong? Both X/Y's are on concurrent matrices, so what is it?
