GUIlayout scrollbar, Not working well...

Question

Hi,

I'm trying to add a scroll bar to a menu I have but it comes out like this: alt text

It doesn't even scroll with click or mouse wheel.

The code:

         if (settingsButton){
             GUILayout.BeginArea(new Rect(350, 90, 400, 300),"","box");
             GUILayout.BeginScrollView(scrollPosition,GUILayout.Width(400),GUILayout.Height(300));
             GUILayout.Box("Settings:");
             GUILayout.Space(5);
             GUILayout.Box("Sound:");
             GUILayout.Label("Volume:");
             GUILayout.BeginHorizontal();
             AudioListener.volume = GUILayout.HorizontalSlider (AudioListener.volume, 0.0f, 1.0f);
             GUILayout.Label(""+ AudioListener.volume.ToString("0.0"),"labelSound",GUILayout.MaxWidth(100));
             GUILayout.EndHorizontal();
             GUILayout.Space(10);
             GUILayout.Box("Grahpics:");
             GUILayout.Space(500); // test scroll
             fullscreenBool = GUILayout.Toggle(fullscreenBool,"FullScreen?");
             FullScreen();
             GUILayout.EndScrollView();
             GUILayout.EndArea();    
         }

Without the GUIlayout.height/width it looks how its meant to, but still it does not scroll with mouse or click.

You need to store the scrollposition as well.

Here is a example from the documentation:

  var scrollPosition : Vector2 = Vector2.zero;
  function OnGUI ()
  {
    scrollPosition = GUI.BeginScrollView (Rect (10,300,100,100), scrollPosition, Rect (0, 0, 220, 200));

    GUI.EndScrollView ();
  }

As you see, the function returns a vector value which states where the position of the scroll is. Without storing the scroll position the GUI can't use the scroll function. See the BeginScrollView documentation for more information.

Good luck!
