Thats true, haha. I tried doing something like that but if i do setLocation shouldnt that be in my mainShip actor class? I used my enemyLaser to decrement the health, so how should i go about this? it looks like this: //BadLaser class// public void destroy() { spaceShip ship = (spaceShip) getOneIntersectingObject(spaceShip.class); ImageStrip strip = (ImageStrip) getOneIntersectingObject(ImageStrip.class); GreenfootSound explodeAlien = new GreenfootSound("Explode.wav"); explodeAlien.setVolume(75); World newWorld = null; if(ship != null) { unlock = true; explodeAlien.play(); getWorld().removeObject(ship); getWorld().addObject(ship,311,500); getWorld().removeObject(this); lives.adjustValue(-1); if(lives.getValue()<0) { newWorld = new GameOver(); Greenfoot.setWorld(newWorld); } } }

At the beginning of your 'destroy' method you created a reference to it with 'ship'. Just use 'ship.setLocation...' and remove the 'removeObject(ship)' and 'addObject(ship)' statements in the middle of that method. You should replace them with the 'ship.setLocation' statement.

This line does not make any sense in your code: The strip is not something that is part of the game play itself and having something intersect it is meaningless. It is more like a control or information object. In other words, it does not interact with other objects in the world; only with the user. Besides that, later in the method, you are referring to that object as 'lives', not 'strip' (either will do, but be consistent). To get a reference to the 'strip', use the following: But, you do not need to get the reference to that object, unless the laser object intersects the ship object. There are more instances of code that could be better placed within the method. More preferably would be something like this:
