Cocos2d iphone 更改Cocos2d中对象的状态

首先，我想为自己是一个完全的新手而道歉，但我已经研究过网络，无法找到解决当前问题的方法。 我用switch语句单独设置了3个对象精灵，希望使用我的主游戏层将它们的状态随机更改为一个动画，我已经在对象单独的头文件和实现文件中定义了该动画。 我已经设置了一个self-schedule更新程序和arc4random方法，它可以工作，但不会更改对象的状态，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，我知道这有点混乱，但我仍然是初学者的第一步，如果有人能给我指出正确的方向，那就是如果我以你能理解的方式解释了这一点！我将非常感激

提前感谢您查看此问题

最后，我发现我所需要的只是将以下代码添加到我的TBT gameCharacters voidupdateStateWithDeltaTime中：方法

如果characterState==kStateTest{

    if (characterState != kStateTest) {
        [self changeState:kStateTest];
        return;
    }

现在它工作得很好

再次感谢Mikael帮助我。

您的对象中是否调用了-voidchangeState:CharacterStatesnewState？您可能应该将-voidchangeState:CharacterStatesnewState；从GamePlayLayer.h类移动到对象的头文件中。您好，Mikael，感谢您的响应。在objects.m文件中调用了characterState方法d然后我想我到底在做什么！将它导入gameplaylayer。我也尝试了你的建议，不幸的是我仍然有同样的问题。我想说我终于发现了问题所在，但我想再次表示感谢Mikael
