Unity預處理程序指令錯誤？

Question

我最近在Unity中使用＃region，＃endregion，＃if，＃endif等問題時遇到問題。

我不記得它最初是從哪個版本開始的，但是每當我創建一個新項目時，我根本就不會使用區域。

它總是說存在解析錯誤，然后說類似“ 錯誤CS1027：預期的#endif指令 ”

為了得到這個錯誤，這就是我要做的

#if !UNITY_EDITOR
#endif

我是否在語句之間包含代碼，還是在指令的兩側刪除所有空白都沒有關系。

我有另一個較舊的項目，可以很好地使用#regions和#if語句，不確定是否更改了內容或如何修復它。.我一直在尋找解決方案，似乎沒人這個問題？ 這是Monodevelop中的設置嗎？ 空格？ 某個地方的字符無效？ 我真的不知道為什么會這樣，這讓我發瘋，哈哈。

如果有人有任何建議，我很想聽聽他們的建議！

謝謝你的時間！

編輯：這是#regions在拖放腳本中不為我工作的示例。.（獎勵，免費拖放和腳本！大聲笑）如果它們給您錯誤，也許只是注釋掉它們。 :(

Answer 1

因此，關於您給出的示例。

我將其粘貼到普通Unity5項目中的文件HybFacebookExtensions.cs中。 它運行完美-沒有錯誤。

您的Unity安裝可能存在問題。

不幸的是，沒有人能夠猜測那里出了什么問題。 您還有第二台機器要測試嗎？

---

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

是一個正確的例子。

您可能不小心將其從Debug更改為Release。

注意。 您會非常困惑地得到這些錯誤，

如果您的代碼只是簡單的語法錯誤。

真煩人。 以下示例可能會導致此類異常錯誤：

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