Unity预处理程序指令错误？

Question

我最近在Unity中使用＃region，＃endregion，＃if，＃endif等问题时遇到问题。

我不记得它最初是从哪个版本开始的，但是每当我创建一个新项目时，我根本就不会使用区域。

它总是说存在解析错误，然后说类似“ 错误CS1027：预期的#endif指令 ”

为了得到这个错误，这就是我要做的

#if !UNITY_EDITOR
#endif

我是否在语句之间包含代码，还是在指令的两侧删除所有空白都没有关系。

我有另一个较旧的项目，可以很好地使用#regions和#if语句，不确定是否更改了内容或如何修复它。.我一直在寻找解决方案，似乎没人这个问题？ 这是Monodevelop中的设置吗？ 空格？ 某个地方的字符无效？ 我真的不知道为什么会这样，这让我发疯，哈哈。

如果有人有任何建议，我很想听听他们的建议！

谢谢你的时间！

编辑：这是#regions在拖放脚本中不为我工作的示例。.（奖励，免费拖放和脚本！大声笑）如果它们给您错误，也许只是注释掉它们。 :(

因此，关于您给出的示例。

我将其粘贴到普通Unity5项目中的文件HybFacebookExtensions.cs中。 它运行完美-没有错误。

您的Unity安装可能存在问题。

不幸的是，没有人能够猜测那里出了什么问题。 您还有第二台机器要测试吗？

---

#if !UNITY_EDITOR
Debug.Log("YO");
#endif

是一个正确的例子。

您可能不小心将其从Debug更改为Release。

注意。 您会非常困惑地得到这些错误，

如果您的代码只是简单的语法错误。

真烦人。 以下示例可能会导致此类异常错误：

public Class Teste()
{
.. you meant to put it in here ..
}
#if UNITY_EDITOR
#endif
