Make a vertical scrollbar.

A scrollbar control returns a float value that represents the position of the draggable "thumb" withtin the bar. You can use the value to adjust another GUI element to reflect the scroll position. However, most scrollable views can be handled more easily using a scroll view control.

Vertical Scrollbar in the Game View.

using UnityEngine;
using System.Collections;

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

The styles of the scroll buttons at the end of the bar can be located 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");
