Question

我确定隐藏着一些愚蠢的错误，但我已经在这里呆了2个多小时，似乎无法找到出错的地方。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。

进一步有用的细节：

确切错误如下：

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，但不计算得分，我希望得分计算。我已经三次检查我的所有实例名称都是正确的，我真的没有看到我在那里做了什么。可能我不知何故可能错误地引用它们，但代码中使用的所有名称都在我的符号和文本内的对象......等等。

非常感谢你的时间，这真的让我很伤心。

P.S .---我正在关注一个教程，所以如果我做了一些不必要的事情，不要怪我！虽然其他评论除了帮助我回答这个难题外，欢迎=）。

Answer 1

正如Josh已经指出的那样，不能保证gameScore和gameClock对象实际上是Counter的实例。

我们需要查看实例化它的代码/位置。

一些可能的选择;

gameScore和gameClock不是实际的Counter实例
您将计数器实例化为MovieClip，因此您已将其添加到舞台上，但您可能没有正确地将Library资产和Counter类连接在一起。

您可以将Counter构造函数更改为此并运行它;

public function Counter()
{
    trace("i am a counter");
    reset();
}

...您应该看到两次跟踪输出（对于gameScore和gameClock），如果您没有看到跟踪输出，则不会构建Counter，这意味着gameScore和gameClock只是普通的MovieClip实例。
