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);
	}
}
```

```
var hSbarValue : float;

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

### Finding extra elements 查找额外的元素：

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.

滚动条两端的按钮的样式是在当前皮肤中搜索 "leftbutton"和"rightbutton"样式名字确定。滚动条滑块的样式是搜索
"thumb"的样式名。

```
var scrollPos : float = 0.5;
// This will use the following style names to determine the size / placement of the buttons
//这将使用跟随的样式名字来确定按钮的大小/ 放置
// MyScrollbarleftbutton - Name of style used for the left button. 
//MyScrollbarleftbutton - 用于左边按钮样式的名字
// MyScrollbarrightbutton - Name of style used for the right button.
//MyScrollbarrightbutton  - 用于右边按钮样式的名字
// MyScrollbarthumb - Name of style used for the draggable thumb.
//MyScrollbarthumb  - 用于拖动滑块样式的名字
function OnGUI() {
	scrollPos = GUI.HorizontalScrollbar(Rect(0,0,100,20), scrollPos, 1, 0, 100, "Scroll");
