I would make the ball responsible for checking if it collides with the paddle because the ball's behavior/state will change - not the paddle's, nor does the state of the 'game' really change.
An alternative would be to create a CollissionControler.as that does all your hit testing for you. This may become useful when you add the bricks or other objects that need to check for collisions. -Dan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Paul Steven Sent: Wednesday, December 13, 2006 8:02 AM To: 'Flashcoders mailing list' Subject: [Flashcoders] AS2 OOP Class Structure for simple pong type game I am creating a simple pong / breakout / arkanoid game in AS2 and not sure how best to deal with the classes. So far I have a Game.as class, a Paddle.as class and a Ball.as class. I need to detect when the ball (or balls) collide with the Paddle. My question is, which class should check for this collision? Should the Game class do this or should I pass a reference to the Paddle into the Ball class so the Ball is able to check this collision itself? If it is the Game class, then I guess it is a case of giving both the Paddle and Ball classes a method to return their current position and then letting the Game class compare these positions to determine if a collision has occurred? If the Ball class needs to have a reference to the Paddle passed to it, I am not sure how this is done. So I would appreciate any advice on this. I appreciate there are probably a lot of different solutions to this, but I am trying to get off on the right footing with this OOP programming.
