unity 实现发布win平台无边框以及窗口置顶

最近需要用到win平台无边框以及窗口置顶,并且可以给用户自己配置窗口大小,多说无益放代码:

using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Diagnostics;
using UnityEngine;
using System.Xml.Serialization;

public class WinMod : MonoBehaviour
{
    public Rect screenRect;
    [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 IntPtr GetForegroundWindow();
    [DllImport("User32.dll", EntryPoint = "FindWindow", CharSet = CharSet.Auto)]
    private static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
    [System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint = "SetForegroundWindow")]
    public static extern bool SetForegroundWindow(IntPtr hWnd);//设置此窗体为活动窗体

    // not used rigth now
    //const uint SWP_NOMOVE = 0x2;
    //const uint SWP_NOSIZE = 1;
    //const uint SWP_NOZORDER = 0x4;
    //const uint SWP_HIDEWINDOW = 0x0080;
    private const uint SWP_SHOWWINDOW = 0x0040;
    private const int GWL_STYLE = -16;
    private const int WS_BORDER = 1;

    private const string folder = "/WinXML/";
    private const string file = "win.xml";
    private const int defaultWidth = 1280;
    private const int defaultHeight = 720;
    private IntPtr handler;

    private void Start()
    {
#if !UNITY_EDITOR     
        string name = Application.productName;
        handler = FindWindow(null, name);
        if (handler == IntPtr.Zero){
            handler = GetForegroundWindow();
        }
        SetForegroundWindow(handler);
        SetWindowLong(handler, GWL_STYLE, WS_BORDER);
        CreateDirectory(Application.streamingAssetsPath + folder);
        ScreenInfo info = LoadXml(Application.streamingAssetsPath + folder + file);
        bool result = SetWindowPos(handler, -1, (int)info.posX, (int)info.posY, (int)info.width, (int)info.height, SWP_SHOWWINDOW);
#endif
    }

    private void CreateDirectory(string path)
    {
        if (!Directory.Exists(path)) Directory.CreateDirectory(path);
    }

    private ScreenInfo LoadXml(string path)
    {
        ScreenInfo info;
        if (File.Exists(path))
        {
            //TODO 文件存在 加载XML
            string text = File.ReadAllText(path);
            StringReader sr = new StringReader(text);
            XmlSerializer ser = new XmlSerializer(typeof(ScreenInfo));
            info = (ScreenInfo)ser.Deserialize(sr);
            sr.Close();
        }
        else
        {
            //TODO 文件不存在 创建XML
            info = new ScreenInfo()
            {
                height = screenRect.height == 0 ? defaultHeight : screenRect.height,
                width = screenRect.width == 0 ? defaultWidth : screenRect.width,
                posX = screenRect.x,
                posY = screenRect.y
            };
            XmlSerializer ser = new XmlSerializer(typeof(ScreenInfo));
            StringWriter sw = new StringWriter();
            ser.Serialize(sw, info);
            sw.Close();
            string text = sw.ToString();
            File.WriteAllText(path, text);
        }
        return info;
    }


}

[Serializable]
public class ScreenInfo
{
    public float width;
    public float height;
    public float posX;
    public float posY;
}

直接将脚本挂在场景中就行,第一次运行时候会自动创建streamingAssets文件夹 并且下面自动创建一个xml文件,
xml文件可以配置窗口大小以及窗口位置.有用处 点个赞 新人博主 谢谢
