JavaScript

var vSbarValue : float;

function OnGUI () {
    vSbarValue = GUILayout.VerticalScrollbar(vSbarValue, 1.0, 10.0, 0.0);
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public float vSbarValue;
    void OnGUI() {
        vSbarValue = GUILayout.VerticalScrollbar(vSbarValue, 1.0F, 10.0F, 0.0F);
    }
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    public vSbarValue as single

    def OnGUI():
        vSbarValue = GUILayout.VerticalScrollbar(vSbarValue, 1.0F, 10.0F, 0.0F)

Finding extra elements:
The styles of the buttons at then end of the scrollbar are searched for in the current skin by adding "upbutton" and "downbutton" to the style name. The name of the scrollbar thumb (the thing you drag) is found by appending "thumb" to the style name.var scrollPos : float = 0.5;
// This will use the following style names to determine the size / placement of the buttons
// MyVerticalScrollbarupbutton - Name of style used for the up button.
// MyVerticalScrollbardownbutton - Name of style used for the down button.
// MyVerticalScrollbarthumb - Name of style used for the draggable thumb.
function OnGUI() {
scrollPos = GUILayout.HorizontalScrollbar (scrollPos, 1, 0, 100, "MyVerticalScrollbar");
