In most games, we can win or lose. This makes the game interesting. In our game, we will win the game if we avoid losing. To be more specific, we will lose if we allow some number of the birds to fly away, for example, 3 birds out of 20. If we'll hit more than 17 birds, then we'll win.
Let's add the code to win and lose the game:
Open the
GameScene.hfile and addenumwith game states and a property to hold the current state, as shown in the following code:#import "CCScene.h" typedef enum GameState { GameStateUninitialized, GameStatePlaying, GameStatePaused, GameStateWon, GameStateLost } GameState; @interface GameScene : CCScene @property (nonatomic, assign) GameState gameState; @end
Switch to the
GameScene.mfile and add the following instance variables:@implementation GameScene { //..skipped.. int _birdsToSpawn; int _birdsToLose; }Initialize the state property and the variables that we've added before in...
