PODifficulty with implementing MVC design (iOS game)
text
Body
copied!<p>I started developing a simple card game iPhone app, but I've been completely stuck for a few days. This is my first program that I will be making outside of CS classes so needless to say it is 20x bigger than anything I've ever done. I have a good idea of basic OO practices and the simpler patterns, but I am struggling in creating a good Model-View-Controller. I could possibly hammer out some procedural and tightly coupled app, but I'd like to use good OO practices. I want to avoid using the Singleton pattern.</p> <p>I understand the big picture, but I get confused when I try to wrap my head around its actual implementation.</p> <p>So far I have (not using the exact APIs atm like UIView):</p> <p><strong>A GameModel class</strong> with instance variables Player *player, Player *dealer, and Deck *gameDeck. Methods are -(void) dealCardtoPlayer, -(Player *) getPlayer(so the view/controller can use reference to get score easily), etc... The Player classes have information like hand and score. This is actually an implementation of a protocol so I can utilize a state pattern if I need to.</p> <p><strong>A GameController class</strong>. Contains references to the GameModel and GameView. That's all I can figure out. If someone clicks on a <em>hit</em> button in the GameView, does that button's method simply call a hitPressed method in the controller which then calls the GameModel method -(void) dealCardtoPlayer:(Card *) topcard? Does the controller constantly poll the model to determine if the player lost or does the model register the controller as an observer and update it?</p> <p><strong>GameView class</strong>. Contains references to the GameModel and GameController(since it sends input to the controller). Does this simply call something like getPlayerHand in the model 60 times/second until it finds a card was added to the hand and then render it ? How would animation be handled? Would the view have its own array of already rendered card elements and transform them(to make room for the new card) once it detects a new card in the player hand and then render the new card? I feel like I should make a state pattern for this too. I think I also read somewhere that animation data is stored in the model, but I'm not sure how.</p> <p><em><strong>Other Random Questions:</em></strong> Does the AI use the same exact controller reference as the player and send its simulated input to the controller? I also want to implement multiplayer later on.</p> <p>I was also wondering how something like a main menu and a pause menu are implemented. Would I use some master controller that controls two MVCs or just switch views in the same GameController? My first guess was the controller would have a menuButtonPressed method that would assign a different view reference (writes over the existing view and gets cleared and deallocated when game is resumed so you see the previous one). If I want to use the same engine to make a side-scroller next how would two controllers work together (I know collision detection usually has its own controller)?</p> <p>I always learn best by example: I've searched Google, but either I'm missing some hidden gems or I can't find the info I need. </p> <p><strong>Primary question:</strong> Are there any must read in-depth tutorials or great books on actually implementing OO/MVC game design?</p> <p>I apologize for the onslaught of long-winded questions, but I really feel like I cannot wrap my head around the intricacies of MVCs. I feel like this app will take months to just get something basic running (it will once classes start again)...</p>
