cocos2d-iphone – Cocos2d淡入/淡出动作,永远重复

我正在尝试为我的基于CCSprite的Player类创建一个方法来启动播放器实例淡入和淡出,直到通过调用stopAllActions停止.

在我的Player类中,我有：

- (void)pulse
{
    [self setOpacity:1.0];
    CCAction *fadeIn = [CCFadeTo actionWithDuration:0.5 opacity:0.5];
    CCAction *fadeOut = [CCFadeTo actionWithDuration:0.5 opacity:1.0];

    CCSequence *pulseSequence = [CCSequence actions:
                                 fadeIn, // I get a warning about incompatible pointer types...
                                 fadeOut, 
                                 nil];
    [self runAction:pulseSequence];
}

这不起作用,也没有解决永远重复的问题.我知道我应该使用CCRepeatForever,但我没有看到如何正确实现它.

谢谢！

我没有运行这个,但我认为其他人已经成功了：

- (void)pulse
{
    [self setOpacity:1.0];
    CCFadeTo *fadeIn = [CCFadeTo actionWithDuration:0.5 opacity:127];
    CCFadeTo *fadeOut = [CCFadeTo actionWithDuration:0.5 opacity:255];

    CCSequence *pulseSequence = [CCSequence actionOne:fadeIn two:fadeOut];
    CCRepeatForever *repeat = [CCRepeatForever actionWithAction:pulseSequence];
    [self runAction:repeat];
}
