Question

我想知道为什么我的completeText变量不会进入我用于GUI标签的IF语句，当用户将鼠标悬停在不同的模型上时。我已成功使用StreamReader导入文本，但是当我放入：

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

进入IF声明没有出现。任何帮助将不胜感激。

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

不会将completeText变量绑定到Label。它只是将completeText中的值复制到标签中。

对completeText的进一步更改不会影响标签显示的内容。

文本变量未转入IF语句
