更改Cocos2d中的对象的状态

首先，我想为成为一名完整的新手道歉，但我已经研究过网络，无法找到解决当前问题的解决方案。我有3个对象（精灵），我用开关语句单独设置，并且想要使用我的主要游戏层来随机将它们的状态更改为我已经在对象中定义的动画单独的头文件和实现文件。我建立了一个自调度更新器和arc4random方法，但它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。更改Cocos2d中的对象的状态

我列出了下面的代码，我知道这是一个混乱，但仍然非常在我作为初学者的第一步，如果任何人都可以指出我在正确的方向（这是如果我已经解释了这一点一种你可以理解的方式！）我会非常感激。

感谢提前甚至在看这个问题。

是 - （void）changeState：（CharacterStates）newState甚至在你的对象中调用？ – Mikael

你应该可能移动“ - （void）changeState :(CharacterStates）newState;”从你的GamePlayLayer.h类到你的对象的头文件。 – Mikael

嗨Mikael，谢谢你的回应。在对象.m文件中调用（characterState）方法，然后（我以为我在做什么！）将其导入到游戏玩家。 –

终于找到了所有我需要的是下面的代码添加到我的TBT gameCharacters-（无效）updateStateWithDeltaTime：方法...

如果（characterState == kStateTest）{

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

现在它工作正常。

再次感谢Mikael试图帮助我。
