错误显示此行（foreach（在obj.transform中转换子级））

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

如果有人知道如何解决，我就无法在任何地方找到正确的答案，然后给我答案

Answer 1

在脚本中用DestroyImmediate()替换Destroy() 。

以下是详细说明：
如果您使用Destroy()函数销毁GameObject ，则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。 因此，如果您在一帧中销毁一个GameObject ，并在完全相同的帧中查询子GameObject ，则获得的数字不会减少。 如果使用DestroyImmediate() ，则在函数签名中标记的GameObject将立即销毁，并且子级计数将立即减少。
在您的情况下，如果已经存在与您创建的字母相同的另一个字母，则CreateWords()函数会破坏创建的字母对象，然后再次调用该函数本身。 但是，即使字母对象被破坏，子计数仍将增加1。最后，该函数将发现每个面板具有6个以上的字母（而实际上没有），从而导致无限递归循环，从而使程序。
