Unity釋出應用程式視窗始終置頂，不被最小化
阿新 • • 發佈：2018-12-18
把這個指令碼直接掛到攝像機就OK了，釋出之後可以看效果，編輯模式下看不到效果
using System.Runtime.InteropServices;
//control the task bar hide or show
//liuyanlei
public class ToolControlTaskBar
{
[DllImport("user32.dll")] //這裡是引入 user32.dll 庫， 這個庫是windows系統自帶的。
public static extern int ShowWindow(int hwnd, int nCmdShow); //這是顯示工作列
[DllImport("user32.dll")]
public static extern int FindWindow(string lpClassName, string lpWindowName); //這是隱藏工作列
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);
}
}
將這個指令碼加入Unity工程，然後，只需要呼叫 ShowTaskBar（），和HideTaskBar（） 就可以控制工作列顯示和隱藏了。
然後再說說遊戲視窗的置頂，和遊戲的視窗隱藏。

這個指令碼掛到場景照相機上就好了， 其實總結起來就是， 通過windows 程式設計的api 找到當前視窗的名字， IntPtr hWnd = FindWindow(null, "udpeffect"); //udpeffect 這個是我unity 打包釋出後的 視窗名字。這裡注意設定。 只有找到這個視窗，才會把這個視窗置頂。 然後設定無邊框。這個指令碼在編輯器下是沒有效果的， 因為 只有打包後才可以，找到這個視窗。
好了，我這裡只是把一些功能集中，其實這些都可以在widnows 程式設計裡面找到。
