Question

我是Cocos2D的新手。我正在为iPhone做一个简单的游戏，我希望我的精灵可以通过一些动画消失。到现在为止，我可以使用以下代码使其消失： -

-(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");
    }   
}

现在我希望精灵可以通过一些动画或任何效果消失。我怎么能这样做？

作为一个例子，这会使你的精灵缩小，直到它消失，然后将它从它的父亲中删除：

-(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:行之上，尝试另一个[sprite runAction:[CCRotateBy actionWithDuration:0.4 angle:360]]

如何使精灵在点击时以各种动画消失？
