创建精灵,以及进行简单的动化,代码如下:

@implementation HelloWorldLayer


// Helper class method that creates a Scene with the HelloWorldLayer as the only child.

+(CCScene *) scene

{

// 'scene' is an autorelease object.

CCScene *scene = [CCScene node];

// 'layer' is an autorelease object.

HelloWorldLayer *layer = [HelloWorldLayer node];

// add layer as a child to scene

[scene addChild: layer];

// return the scene

return scene;

}


- (void) animate_finished

{

    NSLog(@"animation finished!");

}


// on "init" you need to initialize your instance

-(id) init

{

// always call "super" init

// Apple recommends to re-assign "self" with the "super's" return value

if( (self=[super init]) ) {

        CGSize winSize = [[CCDirector sharedDirector] winSize];

        CCSprite *bg = [CCSprite spriteWithFile:@"Icon-72.png"];

        bg.position = ccp(winSize.width*0.5f,winSize.height*0.5f);

        //[bg runAction:[CCMoveTo actionWithDuration:1.0 position:ccp(200,200)]];

        //[bg runAction:[CCRotateBy actionWithDuration:1.0 angle:360]];

        id moveTo = [CCMoveTo actionWithDuration:0.9 position:ccp(200,200)];

        id rotateBy = [CCRotateBy actionWithDuration:0.9 angle:360];

        id callback = [CCCallFuncN actionWithTarget:self selector:@selector(animate_finished)];

        

        [bg runAction:[CCSequence actions:moveTo,rotateBy,callback,nil]];

        


        [self addChild:bg];

}

return self;

}


// on "dealloc" you need to release all your retained objects

- (void) dealloc

{

// in case you have something to dealloc, do it in this method

// in this particular example nothing needs to be released.

// cocos2d will automatically release all the children (Label)

// don't forget to call "super dealloc"

[super dealloc];

}


#pragma mark GameKit delegate


-(void) achievementViewControllerDidFinish:(GKAchievementViewController *)viewController

{

AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];

[[app navController] dismissModalViewControllerAnimated:YES];

}


-(void) leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController

{

AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];

[[app navController] dismissModalViewControllerAnimated:YES];

}

@end
