Unity打包Windows窗口实现放大、缩小、拖拽、无边框

---

---

前言

Unity无边框设置、窗口化放大、缩小、拖拽
提示：PC端打包，测试尽量在打包后测试。
编辑器下测试会有意想不到的后果呦~~

一、引入 user32.dll

[DllImport("user32.dll")]。

二、使用步骤

1.引入库

代码如下：

        [DllImport("user32.dll")]private static extern bool ShowWindow(IntPtr hwnd, int nCmdShow);[DllImport("user32.dll")]private static extern IntPtr GetForegroundWindow();[DllImport("user32.dll")]private static extern IntPtr SetWindowLong(IntPtr hwnd, int _nIndex, int dwNewLong);[DllImport("user32.dll")]private static extern bool SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int X, int Y, int cx, int cy,uint uFlags);[DllImport("user32.dll")]private static extern bool ReleaseCapture();[DllImport("user32.dll")]private static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);

2.功能封装

代码如下：注释详细，不懂就问哈

 public class WindowSetting : MonoBehaviour{[DllImport("user32.dll")]private static extern bool ShowWindow(IntPtr hwnd, int nCmdShow);[DllImport("user32.dll")]private static extern IntPtr GetForegroundWindow();[DllImport("user32.dll")]private static extern IntPtr SetWindowLong(IntPtr hwnd, int _nIndex, int dwNewLong);[DllImport("user32.dll")]private static extern bool SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int X, int Y, int cx, int cy,uint uFlags);[DllImport("user32.dll")]private static extern bool ReleaseCapture();[DllImport("user32.dll")]private static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);const int SW_SHOWMINIMIZED = 2; //{最小化, 激活}const int SW_SHOWMAXIMIZED = 3; //最大化const int SW_SHOWRESTORE = 1; //还原const uint SWP_SHOWWINDOW = 0x0040;const int GWL_STYLE = -16;const int WS_POPUP = 0x800000;private Rect _screenPosition;private IntPtr _handle;/// <summary>/// 放大全屏按钮  缩小按钮  还原窗口按钮  退出按钮/// </summary>public Button bigBtn, smallBtn, restoreBtn, closeBtn;/// <summary>/// 自定义屏幕分辨率 长高/// </summary>private int _screenWidth, _screenHeight;private void Start(){bigBtn.onClick.AddListener(OnClickMaximize);smallBtn.onClick.AddListener(OnClickMinimize);restoreBtn.onClick.AddListener(OnClickRestore);closeBtn.onClick.AddListener(CloseWindow);//自定义窗口分辨率_screenWidth = 1280;_screenHeight = 720;#if UNITY_STANDALONE_WIN && !UNITY_EDITOR //作用是编辑器模式下不运行 尽量打包运行测试Resolution[] r = Screen.resolutions;_screenPosition =new Rect((r[r.Length - 1].width - Screen.width) / 2, (r[r.Length - 1].height - Screen.height) / 2, _screenWidth, _screenHeight);SetWindowLong(GetForegroundWindow(), GWL_STYLE, WS_POPUP);//将网上的WS_BORDER替换成WS_POPUP  _handle = GetForegroundWindow();   //FindWindow ((string)null, "popu_windows");SetWindowPos(GetForegroundWindow(), 0, (int)_screenPosition.x, (int)_screenPosition.y, (int)_screenPosition.width, (int)_screenPosition.height, SWP_SHOWWINDOW);
#endif}/// <summary>/// 最小化 隐藏/// </summary>private static void OnClickMinimize(){ShowWindow(GetForegroundWindow(), SW_SHOWMINIMIZED);}/// <summary>/// 最大化 全屏/// </summary>private static void OnClickMaximize(){ShowWindow(GetForegroundWindow(), SW_SHOWMAXIMIZED);}/// <summary>/// 还原窗口/// </summary>private static void OnClickRestore(){ShowWindow(GetForegroundWindow(), SW_SHOWRESTORE);}/// <summary>/// 退出/// </summary>private void CloseWindow(){Application.Quit();}/// <summary>/// 窗口拖拽区域  此处调用可以在按钮上添加EventTrigger组件 使用Drag方法/// </summary>public void DragWindowsMethod(){ReleaseCapture();SendMessage(_handle, 0xA1, 0x02, 0);SendMessage(_handle, 0x0202, 0, 0);}}

3.效果图如下，绑定自定义按钮
