Question

我正在使用cocos2d并且我有一个for循环来创建一堆精灵，我正在对forloop中的每个精灵运行一个动作，但是当我运行模拟器时我看不到动作..some1请帮助我

           CCAction * action = [CCSequence actions:[CCFadeIn actionWithDuration:2],nil];
           for(NSInteger lp = 0;lp<49;lp++)

    {
        float  sizer = [[numberOfElement objectAtIndex:lp]floatValue];




        CCSprite *_bar = [CCSprite spriteWithFile:colorOfBar rect:        (CGRectMake(10,20,5,sizer*30))];
        _bar.position = ccp(5+9.5*lp,((sizer*30)/2)+25);

        [self addChild:_bar z:1];

        [_bar runAction:action];


    }

您需要为每个节点创建Action实例。

for(NSInteger lp = 0;lp<49;lp++)
{
    float  sizer = [[numberOfElement objectAtIndex:lp]floatValue];

    CCSprite *_bar = [CCSprite spriteWithFile:colorOfBar rect:(CGRectMake(10,20,5,sizer*30))];
    _bar.position = ccp(5+9.5*lp,((sizer*30)/2)+25);

    [self addChild:_bar z:1];

    CCAction * action = [CCSequence actions:[CCFadeIn actionWithDuration:2],nil];
    [_bar runAction:action];
}
