利用GUI.DragWindow()方法
 

GUI.Toggle()
 

var Sli:GUIStyle;
var SliTh:GUIStyle;
var sliderValue:float;
function OnGUI()
{
    sliderValue=GUI.VerticalSlider(Rect(20,20,20,Screen.height-40),sliderValue,0.0,100.0,Sli,SliTh);
}

我给Sli的Normal状态设了一张图片，又给SliTh的Normal状态设了一张图片，但是只能看见滑动条，看不见滑块，哪位高人指点一下，谢谢。

UnityGUI的拓展

 using System;

using System.Collections.Generic;

using UnityEngine;

using Random=UnityEngine.Random;

[ExecuteInEditMode]

public class ListTestPopulator : MonoBehaviour

{

    public int ItemCount = 10;

    private bool _randomItems = true;

    public bool RandomItems = true;

    private BitStage stage;

    public BitList list;

Description

Makes a GUIText label follow an object in 3D space. Useful for things like having name tags over players' heads.

Description

This script allows you to draw a line between two points in the GUI system.

 Usage

Render a line in the GUI system by calling DrawLine and passing it a set of Vector2's for point A and point B of the line.

Optionally, you can pass DrawLine a color and width for the line, as well as using a Rect instead of Vector2's. If you do not pass a width, the line will have a width of 1. If you do not pass a color, the line will be rendered with the GUI.contentColor.

控制类型

 各位大叔大婶大哥大姐，我用U3D时间不久，发现GUI是它最弱的地方，很让人抓狂，不好用。过去用ogre时用Flash做GUI，直接通过C++把ocx贴在Viewport上，Load SWF文件即可。现在很想写个Flash Control插件，求教U3D插件资料，如果可行的话马上建群开工，首先发布在U8上，希望懂U3D底层的C++大虾们给点支持和帮助。
