从函数获取错误 1009?

Question

我收到错误 #1009，但我不知道为什么。我从第 31 行和第 12 行收到错误。这是代码：

第 12 行：

startGenerate();

我想我可能会从函数中得到错误，这是不寻常的。TL、T、TR、CL、C、CR、BL、B 和 BR 都是电影剪辑中的实例名称，所以我知道这不是问题。我的 Flash 项目只有一个帧，我刚才提到的影片剪辑是舞台上唯一的对象。我删除了startGenerate((函数，它工作得很好。我正在制作一个 3x3 版本的熄灯。谢谢。

问题就在这里：

startGenerate();
var randomArray: Array = [];

你应该在调用需要它的函数之前初始化randomArray，而不是之后。
