Look at the first line closely! That is an example of how NOT to get a reference to the tank object ('getLocation' does not return a 'Tank' object; or anything close to it, for that matter).

thanks, so then I have a question for you then. I am trying to get a 'Top' of a tank to turn to face my 'tank' at all times. I have made it possible to turn one time but I seem to not be able to reference it more than one time in the code:
I realize it is only coded to turn to the tank one time but how would I make a reference to the tank in the top without making a new tank?
Tank tank = new Tank();
Enemy enemy = new Enemy();
Top top = new Top();
getWorld().addObject(tank, 547, 346);
tank.setRotation(180);
getWorld().addObject(enemy, 49, 53);
getWorld().addObject(top, enemy.getY(), enemy.getY());
top.turnTowards(tank.getX(),tank.getY());In the act() method of Top class, call 'turnTop();'. Then add the method to the class:
Now, the Top will always turn toward the Tank (as long as the Tank is in the world).
private void turnTop()
{
if (getWorld().getObjects(Tank.class).isEmpty()) return;
Tank tank = (Tank) getWorld().getObjects(Tank.class).get(0);
turnTowards(tank.getX(), tank.getY());
