在游戏视图中的垂直滚动条

using UnityEngine;
using System.Collections;

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

var vSbarValue : float;

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

Finding extra elements 查找额外的元素：

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.

滚动条两端的按钮的样式是在当前皮肤中搜索 "upbutton"和"downbutton"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
// MyVerticalScrollbarupbutton - Name of style used for the up button.
// MyVerticalScrollbarupbutton -  用于上部按钮的样式名字
// MyVerticalScrollbardownbutton - Name of style used for the down button.
// MyVerticalScrollbardownbutton - 用于底部按钮的样式名字
// MyVerticalScrollbarthumb - Name of style used for the draggable thumb.
// MyVerticalScrollbarthumb - 用于拖动滑块的样式名字
function OnGUI() {
	scrollPos = GUILayout.VerticalScrollbar (scrollPos, 1, 0, 100, "MyVerticalScrollbar");
