Create more text in unity GUI? (C#)

Questions & Answers

I am going to ask this quick question. Say you had something like this:
GUIContent content = new GUIContent(“Text”);

void OnGUI() {
GUI.Box(new Rect(0, 0, Screen.width, Screen.height), content);
GUI.Button(new Rect(0, 20, 100, 20), "Button")
}

How would you add a new line of text to the content multiple times? (Working consistently)

You should follow smallbits advice and use the new unity ui, but to answer your question:
You could do something like

void OnGUI() 
{
     GUI.Box(new Rect(0, 0, Screen.width, Screen.height), content);
     if (GUI.Button(new Rect(0, 20, 100, 20), "Button"))
     {
        content.text += "

more Text";
}
}

"
" is the new line character. I can’t check if it works right now but I think it should.
