User32.dll SetForegroundWindow无法正常工作

Question

我最终需要将游戏屏幕设置为最上面的（前景）窗口。

但是我的函数什么也没做（但是其他user32.dll函数也可以工作）

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

public class DatabaseManager : MonoBehaviour
{



    //DLL imports
    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool SetForegroundWindow(IntPtr hWnd);

    static Process proc = Process.GetProcessesByName("firefox")[0];
    IntPtr ptrFF = proc.Handle;
    //------------------------------------------------------------------------


    void Awake()
    {              
        SetForegroundWindow(ptrFF);
    }

   //Other code functions like Update etc.
}

什么也没有发生，没有错误。有没有办法将窗户强行推向前方
