I have a problem with my game in Java, It runs perfectly fine on windows computers but really laggy on mac (I've tested it on a few, all decent specs).
After looking in the console I get a nullPointerException error! I never noticed it before as it doesn't effect game play! I don't think this is the cause to it slowing down on macs but I'm not too sure.
So I guess I have two problems..
public void keyPressed(KeyEvent key) {
gsm.keyPressed(key.getKeyCode()); (line 120)
}
Here is what the console spat out:
