reply to Illegal State Exception error help

Your 'hitDetection' method calls the 'isTouching' method. If the actor is not in a world, it would be impossible for this to even be checked on (the actor will not even know what world to look for collision in -- because there is no world to do it in). Your 'act' method removes the actor when it reaches near the top of the world; then it calls the 'hitDetection' method which requires the actor be in the world before calling the 'isTouching' method, throwing the error. By ensuring that the actor is in a world (the 'getWorld' method returns which world, if any, the object is in), the error can be avoided. If it is not in a world the value returned is 'null', meaning that no world currently has the actor in it. If the value returned is not 'null', then a World object is returned and we can then proceed to call any of the collision checking, location getting and movement methods.
