if(r1 != _gameModel.paddle) { r1.visible = false; } //If a collision isn't found on the sides of the rectangle, //this method calls checkCornerCollision to check whether //the ball has hit any of the corners } //Check for a collision with the rectangle's four corners private function checkCornerCollision ( circle:CircleModel, corner_X:Number, corner_Y:Number, bounceAmount:Number ):void { // Bounce the ball if it hits a corner, set the //rectangle's visible property to "false" so that it's //flagged for removal by the enterFrameHandler if(r1 != _gameModel.paddle) { r1.visible = false; } } } } The GameController is the brains of the game. It takes on many of the roles that had been the responsibility of the application classes in our previous example files. The first thing it does is to create the objects. The paddle object is its own self-contained MVC system. _paddleModel = new RectangleModel(150, 25); _MousePaddleController = new MousePaddleController(_paddleModel); _MousePaddleView = new MousePaddleView (_paddleModel, _MousePaddleController, _stage); _paddleView = new RectangleBlockView(_paddleModel); The MousePaddleController very simply fixes the paddle s x position to the mouse position. (You ll find it in the com.friendsofed.gameElements. primitives package.) The next bit is interesting: the paddle model is passed to the GameModel s paddle property. _gameModel.paddle = _paddleModel;

From now on, whenever the GameController needs to access the paddle, it does so through the GameModel. This is centralized so that other objects, like the GameView, can access it. The efficiency of this won t be immediately obvious in a small example, but in a complex game, it means that multiple views can access the same data from a common location in the GameModel. Next, the paddle view is added to the GameModel s screen sprite. _gameModel.screen.addChild(_paddleView); All the views of the game objects will be added to the GameModel s screen sprite. The GameView can then access and display them. Figure 4-55 illustrates how this all fits together.

Figure 4-55. The GameController creates the game objects and stores them in the GameModel. The GameView reads them from the GameModel. The GameController also gives the game objects their initial positions and colors. _gameModel.paddle.setX = _stage.stageWidth * 0.5; _gameModel.paddle.setY = _stage.stageHeight - _gameModel.paddle.height * 0.5; _gameModel.paddle.color = 0x4E4E4E; But hold on a moment! This is visual information relating to the display. In an MVC system, isn t that the job of the view Shouldn t positions and colors be assigned in the GameView Let s review what we know about MVC: Only the controller should change values in the model. The view should only read the model s data. If the view needs any values changed, it should pass that request to the controller first.

Our GameController code is sticking to this formula. The x, y, and color information are all properties of objects that exist in the GameModel. That means that only the GameController should be allowed to change it. It s visual data, yes, but it s data. All data visual or otherwise should be centralized in the GameModel, and only the GameController can change it. However, that doesn t prevent the GameView from creating its own objects and accessing them directly. In this simple example, the GameView creates a StatusBox object to display the score. The GameModel doesn t need to know anything about the StatusBox, because the StatusBox has nothing to do with the data of the game. It s purely for display purposes. The GameView can create and modify any other objects it needs, like borders, buttons, or menus to showcase that data. The only thing it can t do is directly change properties in the GameModel. It can t change the properties of the game objects. If it thinks it needs to, it should send all those requests to the GameController.
