iphone - 如何让 Sprite 在点击时随着各种动画消失？

Question

我是 Cocos2D 的新手。我正在为 iPhone 制作一个简单的游戏，我希望我的 Sprite 随着一些动画消失。到目前为止，我可以使用以下代码让它消失:-

-(void)selectSpriteForTouch:(CGPoint)touchLocation
{ 

    for (CCSprite *sprite in targets)  
    {

        if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) 
        {
            NSLog(@"sprite was touched");

            [sprite.parent removeChild:sprite cleanup:YES];
            [[SimpleAudioEngine sharedEngine] playEffect:@"pop.wav"];
            [[SimpleAudioEngine sharedEngine] setEffectsVolume:4.0f];

        }
    }
}

-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{

    for( UITouch *touch in touches )
    {

        CGPoint location = [touch locationInView: [touch view]];

        location = [[CCDirector sharedDirector] convertToGL: location];

        [self selectSpriteForTouch:location];
        NSLog(@"touch was detected");
    }   
}

现在我想让 Sprite 消失并带有一些动画或任何效果。我该怎么做？

例如，这会使您的 Sprite 缩小直到消失，然后将其从其父级中移除:

-(void)selectSpriteForTouch:(CGPoint)touchLocation
    ...
    if (CGRectContainsPoint(sprite.boundingBox, touchLocation))
    {
        [sprite runAction:[CCSequence actions:
            [CCScaleTo actionWithDuration:0.4 scale:0],
            [CCCallFuncO actionWithTarget:self selector:@selector(removeSprite:) object:sprite],
            nil]];
            ...//play audio etc
    }
    ....
}

-(void) removeSprite:(CCSprite*) s
{
    [s.parent removeChild:s cleanup:YES];
}

对于其他操作，请尝试 CCMoveTo 或 CCJumpTo 或 CCRotateBy。您可以一次运行多个操作，因此在我提供的 runAction: 行上方，尝试另一个 [sprite runAction:[CCRotateBy actionWithDuration:0.4 angle:360]]
