See Also: Handles.BeginGUI.


GUI in the Scene View.

// Change the transform values for the selected object.
// When selected this script starts and the handleExample is managed.
// The HandlesGUI.BeginGUI() and EndGUI() functions allow the shieldArea
// to be changed back to five, which is the starting value.

Add a script that specifies the object that can be animated in the SceneView.

    public float shieldArea = 5.0f;
}
