设置窗口透明、窗口置顶、鼠标穿透

方法一、

缺点：边缘不平滑，有毛边

关键代码

Shader "Custom/ChromakeyTransparent" {    Properties {        _MainTex ("Base (RGB)", 2D) = "white" {}        _TransparentColourKey ("Transparent Colour Key", Color) = (0,0,0,1)        _TransparencyTolerance ("Transparency Tolerance", Float) = 0.01     }    SubShader {        Pass {            Tags { "RenderType" = "Opaque" }            LOD 200                     CGPROGRAM             #pragma vertex vert            #pragma fragment frag            #include "UnityCG.cginc"             struct a2v            {                float4 pos : POSITION;                float2 uv : TEXCOORD0;            };             struct v2f            {                float4 pos : SV_POSITION;                float2 uv : TEXCOORD0;            };             v2f vert(a2v input)            {                v2f output;                output.pos = mul (UNITY_MATRIX_MVP, input.pos);                output.uv = input.uv;                return output;            }                     sampler2D _MainTex;            float3 _TransparentColourKey;            float _TransparencyTolerance;             float4 frag(v2f input) : SV_Target            {                // What is the colour that *would* be rendered here?                float4 colour = tex2D(_MainTex, input.uv);                             // Calculate the different in each component from the chosen transparency colour                float deltaR = abs(colour.r - _TransparentColourKey.r);                float deltaG = abs(colour.g - _TransparentColourKey.g);                float deltaB = abs(colour.b - _TransparentColourKey.b);                 // If colour is within tolerance, write a transparent pixel                if (deltaR < _TransparencyTolerance && deltaG < _TransparencyTolerance && deltaB < _TransparencyTolerance)                {                    return float4(0.0f, 0.0f, 0.0f, 0.0f);                }                 // Otherwise, return the regular colour                return colour;            }            ENDCG        }    }}

using System;using System.Runtime.InteropServices;using UnityEngine; public class TransparentWindow : MonoBehaviour{    [SerializeField]    private Material m_Material;     private struct MARGINS    {        public int cxLeftWidth;        public int cxRightWidth;        public int cyTopHeight;        public int cyBottomHeight;    }     // Define function signatures to import from Windows APIs     [DllImport("user32.dll")]    private static extern IntPtr GetActiveWindow();     [DllImport("user32.dll")]    private static extern int SetWindowLong(IntPtr hWnd, int nIndex, uint dwNewLong);         [DllImport("Dwmapi.dll")]    private static extern uint DwmExtendFrameIntoClientArea(IntPtr hWnd, ref MARGINS margins);      // Definitions of window styles    const int GWL_STYLE = -16;    const uint WS_POPUP = 0x80000000;    const uint WS_VISIBLE = 0x10000000;     void Start()    {        #if !UNITY_EDITOR        var margins = new MARGINS() { cxLeftWidth = -1 };         // Get a handle to the window        var hwnd = GetActiveWindow();         // Set properties of the window        // See: https://msdn.microsoft.com/en-us/library/windows/desktop/ms633591%28v=vs.85%29.aspx        SetWindowLong(hwnd, GWL_STYLE, WS_POPUP | WS_VISIBLE);                 // Extend the window into the client area        See: https://msdn.microsoft.com/en-us/library/windows/desktop/aa969512%28v=vs.85%29.aspx         DwmExtendFrameIntoClientArea(hwnd, ref margins);        #endif    }     // Pass the output of the camera to the custom material    // for chroma replacement    void OnRenderImage(RenderTexture from, RenderTexture to)    {        Graphics.Blit(from, to, m_Material);    }}

下面是改进版，添加窗口置顶和鼠标穿透，不过依然存在毛边现象，shader还是用上面的

using System;using System.Runtime.InteropServices;using UnityEngine; public class TransparentWindow :MonoBehaviour{    [SerializeField]    public Material m_Material;    private struct MARGINS    {        public int cxLeftWidth;        public int cxRightWidth;        public int cyTopHeight;        public int cyBottomHeight;    }    // Define function signatures to import from Windows APIs    [DllImport("user32.dll")]    private static extern IntPtr GetActiveWindow();    [DllImport("user32.dll")]    private static extern uint SetWindowLong(IntPtr hWnd, int nIndex, uint dwNewLong);    [DllImport("Dwmapi.dll")]    private static extern uint DwmExtendFrameIntoClientArea(IntPtr hWnd, ref MARGINS margins);    [DllImport("user32.dll")]    private static extern uint GetWindowLong(IntPtr hwnd,int nIndex);    [DllImport("user32.dll")]    private static extern int SetLayeredWindowAttributes(IntPtr hwnd,int crKey,int bAlpha,int dwFlags);    ///        /// 窗口置顶    ///

         [DllImport("user32.dll")]    private static extern int SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int y, int Width, int Height, int flags);    ///        /// 得到当前活动的窗口       /// 
       /// 
            [DllImport("user32.dll")]    private static extern IntPtr GetForegroundWindow();   const uint LWA_COLORKEY = 0x1;    // Definitions of window styles    const int GWL_STYLE = -16;    const uint WS_POPUP = 0x80000000;    const uint WS_VISIBLE = 0x10000000;       private const uint WS_EX_LAYERED = 0x80000;    private const int WS_EX_TRANSPARENT = 0x20;     private const int GWL_EXSTYLE = (-20);    private const int LWA_ALPHA = 0x2;    IntPtr hwnd;    void Start()    {        Application.runInBackground=true;       var margins = new MARGINS() { cxLeftWidth = -1 };        hwnd = GetActiveWindow();        DwmExtendFrameIntoClientArea(hwnd, ref margins);        WindowTop();        chuantoulong();    }    ///      /// 设置窗体置顶    /// 
     private void WindowTop()    {        SetWindowPos(GetForegroundWindow(), -1, 0, 0, 0, 0, 1 | 2);                      uint intExTemp = GetWindowLong(hwnd, GWL_EXSTYLE);         }        ///     /// 鼠标穿透    /// 
    public void chuantoulong()    {            SetWindowLong(hwnd, GWL_EXSTYLE, WS_EX_TRANSPARENT | WS_EX_LAYERED);          }    public void chuantoulong_fan()    {        SetWindowLong(hwnd, GWL_EXSTYLE, WS_EX_TRANSPARENT);    }    void OnRenderImage(RenderTexture from, RenderTexture to)    {             Graphics.Blit(from, to, m_Material);    }    const int WS_BORDER = 0;            }

方法二、

注意，需要将Camera设置为Solid Color，并将颜色改为黑色

去掉加载时窗体闪一下的效果

注：去掉边框的巧妙方法，适用于任何unity打包出来的exe，而且不用写一句代码。

步骤：

1、输入cmd，打开命令行。

2、在命令行上输入exe的路径 \***\***.exe

3、然后在后面敲一个空格，输入-popupwindow

4、回车

这样操作下来，程序运行起来是没有边框的。

同样：将-popupwindow 改为，-nolog 程序运行起来就会没有output_log.txt log文件。

妙用还有很多，请参考官方文档
