文本變量不會轉移到IF語句

Question

我想知道爲什麼我的completeText變量不會攜帶到我用於GUI標籤的IF語句中，這些標籤在用戶懸停在不同模型上時顯示。我成功地使用StreamReader導入了文本，但是當我放入時：

  GUI.contentColor = Color.red; 
      GUI.Label(new Rect(1000, 50, 400, 400), completeText); 

進入IF語句沒有出現任何內容。任何幫助將不勝感激。

呼叫

GUI.Label(new Rect(1000, 50, 400, 400), completeText); 

的completeText變量到標籤不結合。它只是將completeText中的值複製到標籤中。

對completeText的進一步更改不會影響標籤顯示的內容。
