首先，我想为一个完整的新手道歉，但我已经研究过网络，无法找到解决当前问题的方法。 我有3个对象（精灵），我已经使用switch语句单独设置，并希望使用我的主游戏区域将其状态随机更改为我已经在对象单独的标题和实现文件中定义的动画。 我已经设置了一个自我调度updater和arc4random方法，但它不会改变对象的状态，因为它只调用我也包含在语句中的CCLOG。
我已经列出了下面的代码，我知道这有点乱，但我仍然非常在成为初学者的第一步，如果有人可以指出我正确的方向（如果我已经解释了这个你可以理解的方式！）我将非常感激。
提前感谢您查看此问题。

答案 0 :(得分：0)
最后发现我需要的只是将以下代码添加到我的TBT gameCharacters-（void）updateStateWithDeltaTime：method ...
if（characterState == kStateTest）{
if (characterState != kStateTest) {
[self changeState:kStateTest];
return;
}
现在它运作正常。
再次感谢Mikael试图帮助我。
