几个CClabelTTF的动画

Question

为CCLabelTTF制作了动画，只需按下一个按钮即可触发。但是，如果我将此动画用于某些CCLabelTTF，则该动画仅适用于后者。怎么啦？

        id scaleDown = [CCScaleTo actionWithDuration:.4 scale:0.5];
        id scaleUp = [CCScaleTo actionWithDuration:.2 scale:1.5];
        id scaleBack = [CCScaleTo actionWithDuration:.2 scale:1.0];
        id combination = [CCSequence actions:scaleDown, scaleUp, scaleBack, nil];
        id repeat = [CCRepeat actionWithAction:combination times:3];
        [Var1Podpis,Var2Podpis,Var3Podpis runAction:repeat];

Answer 1

不能在多个目标上同时执行操作...它们包含关于特定目标的状态。您应该将创建repeat的所有代码放在一个方法中，并针对每个目标运行一次。

-(CCAction*) pulseAction {
    id scaleDown = [CCScaleTo actionWithDuration:.4 scale:0.5];
    id scaleUp = [CCScaleTo actionWithDuration:.2 scale:1.5];
    id scaleBack = [CCScaleTo actionWithDuration:.2 scale:1.0];
    id combination = [CCSequence actions:scaleDown, scaleUp, scaleBack, nil];
    id repeat = [CCRepeat actionWithAction:combination times:3];
    return repeat;
}

and then 

[Var1Podpis runAction:[self pulseAction]];
[Var2Podpis runAction:[self pulseAction]];
[Var3Podpis runAction:[self pulseAction]];

或者类似的东西。未测试，从内存中。

Answer 2

 -(void) pulseActionForItem:(CCNode*) item {
        id scaleDown = [CCScaleTo actionWithDuration:.4 scale:0.5];
        id scaleUp = [CCScaleTo actionWithDuration:.2 scale:1.5];
        id scaleBack = [CCScaleTo actionWithDuration:.2 scale:1.0];
        id combination = [CCSequence actions:scaleDown, scaleUp, scaleBack, nil];
        id repeat = [CCRepeat actionWithAction:combination times:3];
        [item runAction:repeat];
    }

self pulseActionForItem:Var1Podpis；....
