unity 判断进程是否挂了，挂了就重启（打开文件，查找进程，延后几秒调用函数）

代码如下：

    void Update()
    {
        if (clientScene.msgCount > preMsgCount)     //长时间没有得到进程的反馈
        {
            preMsgCount = clientScene.msgCount;
            recentGetMsgTick = Time.time;
        }

        if (Time.time > recentGetMsgTick + maxNoMsg)    //长时间没有得到进程的额反馈超过一定时间，说明进程死掉了
        {
            if (CheckProcess(pname))                     //进程存在就杀死并重启
            {
                KillProcess(pname);
                Invoke("StartProcess", 2.0f);           //隔2秒再调用该函数
            }
            else                                        //不存在就开启
            {
                StartProcess();
            }

            recentGetMsgTick = Time.time + clientIdleTime;
        }
    }

    /// <summary>

    void StartProcess()
    {
        UnityEngine.Debug.Log("打开本地应用");
        Application.OpenURL(exe_path);

        NoteReStart();
    }

        int i = 0;
        foreach (Process process in processes)
        {

                        continue;
                    }
                    else if (!process.ProcessName.Contains(processName) && i > processes.Length)
