【问题描述】：
我确信有一些愚蠢的错误瞒着我，但我已经做了 2 个多小时了，似乎找不到问题所在。有人请帮我确定我做错了什么，错误在标题中，以下是我的相关代码。
更多有用的细节：
确切的错误如下：
TypeError：错误 #1006：addToValue 不是函数。 在 SimpleMenuMain/onTick() 在 flash.utils::Timer/_timerDispatch() 在 flash.utils::Timer/tick()
游戏运行，但不计分，我要计分。我已经三次检查了我所有的实例名称是否正确，我真的看不出我在那里所做的有什么问题。可能我以某种方式错误地引用了它们，但是代码中使用的所有名称都在我的符号和文本中的对象上......等等。
非常感谢您抽出宝贵的时间，这真的让我很生气。
P.S.---我正在学习一个教程，所以如果我做了一些不必要的事情，请不要怪我！尽管除了帮助我回答这个难题之外，其他 cmets 也很受欢迎 =)。

【问题讨论】：
-
除非我完全失明，否则您永远不会定义或实例化
gameScore和gameClock，这两个您试图调用addToValue()的对象。不知道为什么这不会引发 null-ref 错误，但这绝对是问题所在。这些对象不存在，因此不能对它们使用该方法。 -
这些都被定义为我的主时间线上的实例......这就是为什么它没有抛出一个完整的错误我认为......只要我给了它们实例名称我认为我应该能够像那样引用它们就好了？
-
它们是
Counter的实例吗？ Counter 具有addToValue()方法，因此他们需要扩展该类才能访问该方法。
