    Unity3D跨屏(píng)幕、全屏顯示方法,運行環境:Win10 64bit, Unity3D 2017.3.1

    using System;
    using System.Collections;
    using System.Runtime.InteropServices;
    using System.Diagnostics;
    using UnityEngine;
    using System.Xml.Serialization;public class WindowMod : MonoBehaviour
    {
        [HideInInspector]
        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 GetActiveWindow();

        const int GWL_STYLE = -16;
        const int WS_BORDER = 1;
        private int i = 0;    void Start()
        {
            SetWindowLong(GetActiveWindow(), GWL_STYLE, WS_BORDER);
            SetWindowPos(GetActiveWindow(), -1, (int)screenPosition.x, (int)screenPosition.y, (int)screenPosition.width, (int)screenPosition.height, SWP_SHOWWINDOW);
        }    void Update()
        {
            i++;
            if(i<5)
            {
                SetWindowLong(GetActiveWindow(), GWL_STYLE, WS_BORDER);
                SetWindowPos(GetActiveWindow(), -1, (int)screenPosition.x, (int)screenPosition.y, (int)screenPosition.width, (int)screenPosition.height, SWP_SHOWWINDOW);
            }
        }
    }


    上麵這個腳本,可以使Unity3D窗口全屏,沒有標題欄,通過更改screenPosition的值,還可以使窗口(kǒu)直接在第二個屏幕上啟(qǐ)動(x=0, y=0, width=1920, height=1080),或(huò)者窗口(kǒu)跨越(yuè)兩(liǎng)個屏(x=0, y=0, width=3840, height=1080)。 如果(guǒ)使用讀取配置(zhì)文件的方法, 可以自定義屏幕分辨率。Windows係統會記錄(lù)軟件的窗口大小和位置,並記錄在注(zhù)冊表的\HKEY_CURRENT_USER\Software\xxx\yyy 位置,xxx是Unity3D在build設置中(zhōng)的Company Name,yyy是(shì)在Build設置中(zhōng)的(de)Product Name。所以如果有時候(hòu)窗口大小有問題,可以先備份注冊表,再刪除xxx項。建(jiàn)議每個項目的Product Name不要用默認值,否(fǒu)則打包出來(lái)的軟件都會對應到注冊表裏相同(tóng)的項。
