[HELP][PUN 2] Not Receiving RPC requests when Time.timeScale set to 0

forgemaster

Hello All

What I am trying to do:
I am trying to make it so that if everyone in the room is "paused" (pressed the escape key) that the game freezes (timeScale = 0) and when 1 person unpauses on there end it unfreezes the game for everyone. Meaning if only 1 person is in the pause menu the game should still resume, only if everyone is in the pause menu that we freeze the game.

The problem:
The problem is once everyone becomes frozen and when 1 person unpauses only that person resumes the game where as everyone else is still frozen.

Code:
private void TogglePauseMenu() {
 Debug.Log("Pressed ESC Key");
 isGamePaused = !isGamePaused;
 PauseMenu.SetActive(isGamePaused);
 photonView.RPC("UpdatePauseStatus", RpcTarget.All, PhotonRoom.GetMyNumberInRoom() - 1, isGamePaused);
}

[ PunRPC ]
private void UpdatePauseStatus(int id, bool isPaused) {
 Debug.Log("Updating Pause Status");
 PauseList[id] = isPaused;
 // check if all players paused
 bool allPaused = true;
 for (int i = 0; i < PauseList.Length; i++)
  if (!PauseList) allPaused = false;
 Time.timeScale = (allPaused) ? 0f : 1f;
 AudioManager.instance.TogglePauseAllAudio(allPaused);
}

Comments:
- I've tried looking everywhere online regarding this situation but still haven't found a solution.

- On the API documentation it claims that MinimalTimeScaleToDispatchInFixedUpdate will ignore timeScale by default, so I thought maybe since my check
if (Input.GetKeyDown(KeyCode.Escape))
  TogglePauseMenu();
was in the Update method that that would be the issue but I tried putting it in FixedUpdate and LateUpdate and the problem still persisted.

- One possible solution I found was that I should set the Time.timeScale to something small like 0.01 but the thing is that it doesn't fully pause the game things the background still move really slowly. If I set it to something like 0.0001 then it's the same as if I set it to 0.

So basically is there a way to sync Time.timeScale accross the network?
Thanks for taking the time to help, I greatly appreciate it!

Has anyone figured out any alternatives? Still dealing with this issue

if (!PauseList) allPaused = false;

This looks suspicious. Shouldn't it be PauseList?
If that doesn't help, create a small repro case and send it (without assets).
Upload to dropbox or such and mail the download link to: developer@photonengine.com

Oops seems like the formatting of my original post didn't include the square bracket I had in my code for accessing the array. Not sure if I can edit the OP but here is the code using code format:

    public void TogglePauseMenu() {
        Debug.Log("Pressed ESC Key");
        isGamePaused = !isGamePaused;
        PauseMenu.SetActive(isGamePaused);
        photonView.RPC("UpdatePauseStatus", RpcTarget.All, PhotonRoom.GetMyNumberInRoom() - 1, isGamePaused);
    }
    [PunRPC]
    private void UpdatePauseStatus(int id, bool isPaused) {
        Debug.Log("Updating Pause Status");
        PauseList[id] = isPaused;
        // check if everyone is paused
        bool allPaused = true;
        for (int i = 0; i < PauseList.Length; i++)
            if (!PauseList[i]) allPaused = false;
        Time.timeScale = (allPaused) ? 0f : 1f;
        AudioManager.instance.TogglePauseAllAudio(allPaused);
    }

So this shouldn't be the problem since the code logic is just checking if at least 1 person is not paused then allPaused = false. (I assume everyone is paused before the for-loop by setting allPaused = true and then we update the bool if we find that 1 person isn't paused)

Another reason this isn't it is because the Debug.Log("Updating Pause Status"); never outputs when everyone is paused and 1 person sends an unpause request. So it never even reaches to that point to begin with.

I will try to recreate this issue in an empty project tomorrow and send it to the email you provided.

Anyway, thanks for the help!

Yes, please try to do a minimal repro case.

There is also another thread in this forum, which is about RPCs and TimeScale. I lost track of it but a search should help. I think there was a solution.

Hi @forgemaster,

Thank you for choosing Photon!

Did you read this?
Did you try

PhotonNetwork.MinimalTimeScaleToDispatchInFixedUpdate = 0;

Oh I must have misread the docs regarding MinimalTimeScaleToDispatchInFixedUpdate, I thought it had to be set to -1 for PUN to recieve RPCs.

Thank you so much, I set the value to 0 and it worked! Cheers!
