关于：Unity3D 发布无边框exe，Unity3D Build exe无边框
Unity发布windows版本 总是带着边框，很想给它去掉，笔者在网上查了一番，常见的有3中。
1：通过unity3d编译命令解决：
-popupwindow (Windows only)The window will be created as a a pop-up window (without a frame).
这个窗口将以弹出的方式创建（没有框架）
笔者就是这样的CMD：
【D:\Program Files (x86)\Unity\Editor>Unity.exe -buildWindowsPlayer "D:\Game.exe" -projectPath "D:\Work\Game3D" -popupwindow -executeMethod CMDBuild.MyBuild -quit】
其中CMDBuild.MyBuild 代码如下：
[MenuItem("Build/BuildWebplayerStreamed")]
static void MyBuild(){
string[] levels= new string[]{"Assets/Scenes/Load.unity", "Assets/Scenes/Main2.unity"};
BuildPipeline.BuildPlayer(levels,"Game.exe",BuildTarget.StandaloneWindows,BuildOptions.BuildAdditionalStreamedScenes);
}

//官方的新命令有所更新，参见：

2：C# 中通过 P/Invoke 调用Win32 DLL。通过user32.dll 完成exe边框的设置。如下建一个WindowMod.cs；
public class WindowMod : MonoBehaviour
{
public Rect screenPosition;
[DllImport("user32.dll")]
static extern IntPtr SetWindowLong(IntPtr hwnd, int _nIndex, int dwNewLong);
[DllImport("user32.dll")]
static extern bool SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
[DllImport("user32.dll")]
static extern IntPtr GetForegroundWindow();
// not used rigth now
//const uint SWP_NOMOVE = 0x2;
//const uint SWP_NOSIZE = 1;
//const uint SWP_NOZORDER = 0x4;
//const uint SWP_HIDEWINDOW = 0x0080;
const uint SWP_SHOWWINDOW = 0x0040;
const int GWL_STYLE = -16;
const int WS_BORDER = 1;
void Awake()
{
screenPosition.x = (int)((Screen.currentResolution.width - screenPosition.width) / 2);
screenPosition.y = (int)((Screen.currentResolution.height - screenPosition.height) / 2);
if(Screen.currentResolution.height<=768){
screenPosition.y = 0;
}
SetWindowLong(GetForegroundWindow(), GWL_STYLE, WS_BORDER);//设置无框；
bool result = SetWindowPos(GetForegroundWindow(), 0, (int)screenPosition.x, (int)screenPosition.y, (int)screenPosition.width, (int)screenPosition.height, SWP_SHOWWINDOW);//exe居中显示；
}
}
