size	How much can we see?

JavaScripts

var hSbarValue : float;

function OnGUI () {
hSbarValue = GUI.HorizontalScrollbar (Rect (25, 25, 100, 30), hSbarValue, 1.0, 0.0, 10.0);
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
public float hSbarValue;
void OnGUI() {
hSbarValue = GUI.HorizontalScrollbar(new Rect(25, 25, 100, 30), hSbarValue, 1.0F, 0.0F, 10.0F);
}
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

public hSbarValue as single

def OnGUI():
hSbarValue = GUI.HorizontalScrollbar(Rect(25, 25, 100, 30), hSbarValue, 1.0F, 0.0F, 10.0F)

Finding extra elements:
The styles of the buttons at the end of the scrollbar are searched for in the current skin by adding "leftbutton" and "rightbutton" 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
// MyScrollbarleftbutton - Name of style used for the left button.
// MyScrollbarrightbutton - Name of style used for the right button.
// MyScrollbarthumb - Name of style used for the draggable thumb.
function OnGUI() {
scrollPos = GUI.HorizontalScrollbar(Rect(0,0,100,20), scrollPos, 1, 0, 100, "Scroll");
}
