【Unity】改变游戏运行时Window的窗口标题

零、需求

Unity打包好的Windows程序，启动后如何更改窗口标题？因为看着英文的感觉不太好，故有此想法。什么？你说为啥不改项目产品名？产品名会被写到文件夹名中，感觉后面可能会有问题……

壹、解决方案

代码如下：

using System.Collections;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using UnityEngine;

public class ChangeWindowTitle : MonoBehaviour
{
    /// <summary>
    /// 记录当前的窗口标题
    /// </summary>
    public static string TitleText = "";
    /// <summary>
    /// 窗口句柄，只能获取一次，后面获取的无效
    /// </summary>
    private static System.IntPtr windowHandle;
    /// <summary>
    /// 是否已经获得窗口句柄
    /// </summary>
    private static bool isGotWindowHandle = false;

    [Header("Windows窗口标题设置")]
    [Tooltip("窗口标题文字")]
    public string title = "窗口";
    [Tooltip("是否自动设置窗口标题文字")]
    public bool autoSet = true;


    [SerializeField]
    [Header("标题设置状态")]
    [Tooltip("标题是否已经设置过至少一次")]
    private bool isSet = false;

#if UNITY_STANDALONE_WIN
    [DllImport("user32.dll")]
    private static extern System.IntPtr FindWindow(string className, string windowName);
    [DllImport("user32.dll", CharSet = CharSet.Unicode, SetLastError = true)]
    private static extern bool SetWindowText(System.IntPtr hwnd, string title);
#endif


    void Update()
    {
        if (autoSet && !isSet)
        {
            setTitle(title);
        }
    }

    public void setTitle(string title)
    {
        isSet = true;
#if UNITY_STANDALONE_WIN
        TitleText = title;
        if(!isGotWindowHandle)
        {
            // 获取窗口句柄
            windowHandle = FindWindow(null, Application.productName);
            isGotWindowHandle = true;
        }
        // 设置新标题
        SetWindowText(windowHandle, title);
#endif
    }
}
