在Unity3d中运行进程时如何做某事

Question

I'm running a process from unity and it kinda take some time(it actually can take up to 30 minutes), however I want unity to run it for maximum 5 minutes and if there was no output, return. I also want to show something like this during this wait for 5 minutes time

anybody has an idea how to do this? I tried using this line of code

    myProcess.WaitForExit(1000 * 60 * 5);

but I can't do anything while it's waiting, I guess it's blocking me or something, can anybody help?

EDITED:

   public void onClickFindSol(){
    paused=true;
    ReadRedFace();
    ReadGreenFace();
    ReadBlueFace();
    ReadYellowFace();
    ReadOrangeFace();
    ReadWhiteFace();
    if (File.Exists (path))
        File.Delete (path);
    System.IO.File.WriteAllText(path,InputToAlgo);      
    myProcess = new Process();
    myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    myProcess.StartInfo.CreateNoWindow = true;
    myProcess.StartInfo.UseShellExecute = false;
    myProcess.StartInfo.RedirectStandardOutput = true;
    myProcess.StartInfo.FileName = (System.Environment.CurrentDirectory )+Path.DirectorySeparatorChar+"rubik3Sticker.ida2";
    myProcess.EnableRaisingEvents = true;
    myProcess.StartInfo.WorkingDirectory = (System.Environment.CurrentDirectory )+Path.DirectorySeparatorChar;
    myProcess.StartInfo.Arguments = "corner.bin edge1.bin edge2.bin";
    myProcess.OutputDataReceived += new DataReceivedEventHandler((sender, e) =>
    {
        if (!String.IsNullOrEmpty(e.Data)){
            timer = 0f;
            StepsOfSolution++;
            print(e.Data);
            solution.output.Add(e.Data);
        }
    });
    myProcess.Start();
    myProcess.BeginOutputReadLine();
}
void Update(){
    if (myProcess != null){
        if(timer>fiveMinutes){
            myProcess.Kill();
            myProcess.Close();
            badExit=true;
            myProcess=null;
            return;
        }
        timer += Time.deltaTime;
        if (!myProcess.HasExited){
            RubikScene.PleaseWait.SetActive(true);
        }
        else{
            if(badExit){
                RubikScene.PleaseWait.SetActive(false);
                RubikScene.TooLong.SetActive(true);
                print("TimeOut!");
            }else{
                paused=false;
                Application.LoadLevel("solution");
            }
        }
    }
}

Do not use myProcess.WaitForExit() . It will block until it returns. Use myProcess.Start() , then in your Update function, run your animation inside if !myProcess.HasExited . Your code is incomplete so I will provide incomplete solution but this should work.

void Start()
{
 timer = 0;//Reset Timer
 myProcess.Start();
}

Check if the process has finished in the Update function

float timer = 0f;
float fiveMinutes = 300; //300 seconds = 5minutes
bool badExit = false;

void Update()
{
 if (myProcess != null)
 {
    //Check if Time has reached
    if(timer>fiveMinutes){
        myProcess.Kill();
        myProcess.Close();
        badExit = true;
        return;
    }
    timer += Time.deltaTime;

   if (!myProcess.HasExited)
   {
    //Do Your Animation Stuff Here
   }else{
      //Check if this was bad or good exit
      if(badExit){
        //Bad
       }else{
        //Good
        }
    }
 }
}

Then somewhere else in your callback function where you receive/read from the process, if the bytes read is >0 then always reset timer to 0 . So that the timer will only count to 5 minutes when it has not received anything for 5 minutes .

myProcess.OutputDataReceived += new DataReceivedEventHandler((sender, e) =>
{
// Prepend line numbers to each line of the output.
if (!String.IsNullOrEmpty(e.Data))
 {
    timer = 0f; //Reset Process Timer
    lineCount++;
    output.Append("\n[" + lineCount + "]: " + e.Data);
 }
});

OR with a callback function

private static void SortOutputHandler(object sendingProcess, 
            DataReceivedEventArgs outLine)
 {
  // Collect the sort command output.
  if (!String.IsNullOrEmpty(outLine.Data))
   {
      timer = 0f; //Reset Process Timer
      numOutputLines++;

      // Add the text to the collected output.
      sortOutput.Append(Environment.NewLine + 
      "[" + numOutputLines.ToString() + "] - " + outLine.Data);
   }
 }
