把这个脚本直接挂到摄像机就OK了，发布之后可以看效果，编辑模式下看不到效果
using System.Runtime.InteropServices;
//control the task bar hide or show
//liuyanlei
public class ToolControlTaskBar
    [DllImport("user32.dll")]   //这里是引入 user32.dll 库， 这个库是windows系统自带的。
    public static extern int ShowWindow(int hwnd, int nCmdShow); //这是显示任务栏
    [DllImport("user32.dll")] 
    public static extern int FindWindow(string lpClassName, string lpWindowName); //这是隐藏任务栏
    private const int SW_HIDE = 0;  //hied task bar
    private const int SW_RESTORE = 9;//show task bar
    // Use this for initialization
    /// <summary>
    /// show TaskBar
    /// </summary>
    public static void ShowTaskBar()
        ShowWindow(FindWindow("Shell_TrayWnd", null), SW_RESTORE);
    /// <summary>
    /// Hide TaskBar
    /// </summary>
    public static void HideTaskBar()
        ShowWindow(FindWindow("Shell_TrayWnd", null), SW_HIDE);

将这个脚本加入Unity工程，然后，只需要调用 ShowTaskBar（），和HideTaskBar（） 就可以控制任务栏显示和隐藏了。
 

然后再说说游戏窗口的置顶，和游戏的窗口隐藏。

这个脚本挂到场景照相机上就好了， 其实总结起来就是， 通过windows 编程的api 找到当前窗口的名字，  IntPtr hWnd = FindWindow(null, "udpeffect"); //udpeffect 这个是我unity 打包发布后的 窗口名字。这里注意设置。 只有找到这个窗口，才会把这个窗口置顶。 然后设置无边框。这个脚本在编辑器下是没有效果的， 因为 只有打包后才可以，找到这个窗口。
 

好了，我这里只是把一些功能集中，其实这些都可以在widnows 编程里面找到。

public class ToolControlTaskBar
    [DllImport("user32.dll")]   //这里是引入 user32.dll 库， 这个库是windows系统自带的。
    pub...
public class WindowAPI : MonoBehaviour
    [DllImport("user32.dll", EntryPoint = "FindWindow")]
    private static extern IntPtr F.
				
做项目遇到一个需求，需要是unity打包出来的程序在运行的时候窗口最大化，并且保持在最上层，最难的是要时刻保持交互，不然输入控制会失效，网上百般查询和亲自验证后，利用window自带的方法实现窗口置顶，然后程序使用鼠标点击屏幕某个位置实现保持交互（这个不完美，但是想不到其它方法实现，有大佬可以指教一下）。
重点：一定要将Update中FindWindow()方法里的程序名称换成自己打包出来的名字。
下面代码：
using System;
using System.Collections;
using

				
这两天玩了玩QQ拖拉机，总觉得记牌没有真打的记得准，所以今天用VB做了一个记牌器。本身没什么难度，最后要用到AlwaysOnTop功能，以前没做过，所以查了一下资料：调用一些API函数即可Private Const SWP_NOSIZE = &H1 
Private Const
