實現步驟：

1.設置MainCamera

2.添加C#腳本

一、設置MainCamera里的Camera組件，以下圖為例子

關鍵點在于 ：

MainCamera->Camera->Clear Flags:Solid Color

MainCamera->Camera->Background:black

二、新建C#腳本，編寫代碼如下（HyalineBackground.cs）

using UnityEngine; using System; using System.Runtime.InteropServices; //MainCamera->Camera->Clear Flags:Solid Color //MainCamera->Camera->Background:black public class HyalineBackground : MonoBehaviour {public string strProduct;//項目名稱private int currentX;private int currentY;#region Win函數常量private struct MARGINS{public int cxLeftWidth;public int cxRightWidth;public int cyTopHeight;public int cyBottomHeight;}[DllImport("user32.dll")]private static extern IntPtr GetActiveWindow();[DllImport("user32.dll")]static extern IntPtr FindWindow(string lpClassName, string lpWindowName);[DllImport("user32.dll")]static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);[DllImport("user32.dll")]static extern int GetWindowLong(IntPtr hWnd, int nIndex);[DllImport("user32.dll")]static extern int SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int X, int Y, int cx, int cy, int uFlags);[DllImport("user32.dll")]static extern int SetLayeredWindowAttributes(IntPtr hwnd, int crKey, int bAlpha, int dwFlags);[DllImport("Dwmapi.dll")]static extern uint DwmExtendFrameIntoClientArea(IntPtr hWnd, ref MARGINS margins);[DllImport("user32.dll")]private static extern int SetWindowLong(IntPtr hWnd, int nIndex, uint dwNewLong);//private const int WS_POPUP = 0x800000;private const int GWL_EXSTYLE = -20;private const int GWL_STYLE = -16;private const int WS_EX_LAYERED = 0x00080000;private const int WS_BORDER = 0x00800000;private const int WS_CAPTION = 0x00C00000;private const int SWP_SHOWWINDOW = 0x0040;private const int LWA_COLORKEY = 0x00000001;private const int LWA_ALPHA = 0x00000002;private const int WS_EX_TRANSPARENT = 0x20;#endregionIntPtr hwnd;void Awake(){#if UNITY_EDITORprint("unity內運行程序"); #elsehwnd = FindWindow(null, strProduct);int intExTemp = GetWindowLong(hwnd, GWL_EXSTYLE);SetWindowLong(hwnd, GWL_EXSTYLE, intExTemp | WS_EX_TRANSPARENT | WS_EX_LAYERED);SetWindowLong(hwnd, GWL_STYLE, GetWindowLong(hwnd, GWL_STYLE) & ~WS_BORDER & ~WS_CAPTION);currentX = 0;currentY = 0;SetWindowPos(hwnd, -1, currentX, currentY, Screen.currentResolution.width, Screen.currentResolution.height, SWP_SHOWWINDOW);var margins = new MARGINS() { cxLeftWidth = -1 };DwmExtendFrameIntoClientArea(hwnd, ref margins); #endif} }

在Hierarchy視圖新建空物體，添加上面建立的腳本組件即可

三、注意代碼設置效果無法體現在編譯器模式，將代碼打包查看效果

注意Player Setting->Resolution and Presentation->Standalone Player Options->Use DXGI Filp Model Swapchain for D3D1為false

此文參考過多篇博客，可以說取其精華，實驗過許多次
