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

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[i]) allPaused = false;
Time.timeScale = (allPaused) ? 0f : 1f;
AudioManager.instance.TogglePauseAllAudio(allPaused);
}

Comments:
[color=#ababab]- 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();
  [color=#ababab]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! :)[/color]

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

if (!PauseList) allPaused = false;  

This looks suspicious. Shouldn't it be PauseList[i]?
If that doesn't help, create a small repro case and send it (without assets).

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! :)
