错误显示这一行 (foreach (Transform child in obj.transform))

在此功能之前，我使用 Gameobject.transform.childcount 它也显示相同的错误

我在任何地方都找不到正确的答案如果有人知道如何解决，请给我答案

Answer 1

将脚本中的 Destroy() 替换为 DestroyImmediate()。

这里有详细的解释：
如果您使用 Destroy() 函数销毁 GameObject，Unity 不会立即销毁它。它实际上所做的只是将其标记为 null 并在以后的帧中销毁它。所以如果你在一帧中销毁一个 GameObject ，并在完全相同的帧中查询子计数，你得到的数字不会减少。如果你用 DestroyImmediate() 来做，函数签名中标记的 GameObject 将立即被销毁，子计数将立即递减。
在您的情况下，如果已经有另一个与您创建的字母相同的字母，则 CreateWords() 函数会销毁创建的字母对象，然后再次调用该函数本身。然而，即使字母对象被销毁，子计数仍然增加 1。最后，函数会发现每个面板都有超过 6 个字母（实际上没有），导致无限递归循环导致崩溃程序。
