Question Await delay.task blocks the browser

Ho Everyone,
First of all, sorry in advance as I am completely new to programming/unity/this forum... I am trying to learn all by myself from scratch for fun, going through all the materials and q&a on the web, but this time I might be stuck as I was not able to find any helpful answer (but sorry if it was somewhere...).

So I developed a very basic "game" just to learn/practice, and I wanted to publish it in webGL format so it can be played from a browser (note that during development my "build setting" was set on Windows platform and I switched to WebGL before building), the problem is that on both unity play and itch.io, it looks like as soon as I reach a "await Task.Delay", the browser blocks...

I checked the browser console that says when the game opens "WebGL warning: clientWaitSync: ClientWaitSync must return TIMEOUT_EXPIRED until control has returned to the user agent's main loop. (only warns once)". That must be it, should be an easy fix but I was unable to find out how to resolve this in my code/unity...

if you have any clue that would be much appreciated.

Anyways, many thanks to the whole community, I wouldn't have come that far without all the answers you provide on various forums.

Here is a link to my game on unity play: https://play.unity.com/mg/other/my-game-that-does-not-work


And the code where the issue seems to be:

Code (CSharp):

1.     public async void SetPlayerName()
2.  
3.         {
4.         if(firstP == true)
5.             {
6.                 PS = PlayerStats.GetComponent<PlayerStats>();
7.                 PS.Player1name = input;
8.                 PS.activePlayer = PS.Player1name;
9.                 PS.PlayerStatsUpdate();
10.                 Player1nameEntered.text = PS.Player1name;
11.                 iTween.ScaleTo(Player1Container, iTween.Hash("x", 4.0f, "y", 4.0f, "time", 1));
12.                 GetComponent<AudioSource>().PlayOneShot(NameAppear);
13.                 await Task.Delay(2000);
14.                 FightImage.SetActive(true);
15.                 iTween.ScaleTo(FightImage, iTween.Hash("x", 2.0f, "y", 2.0f, "time", 1));
16.                 GetComponent<AudioSource>().PlayOneShot(FightAudio);
17.                 inputfieldname.Select();
18.                 inputfieldname.text = "";
19.                 txt.text = "Enter Name of Second Player";
20.                 firstP = false;
21.                 Debug.Log(firstP);
22.                
23.             }
24.         else if(firstP == false)
25.             {
26.                 PS = PlayerStats.GetComponent<PlayerStats>();
27.                 PS.Player2name = input;
28.                 PS.PlayerStatsUpdate();
29.                 Player2nameEntered.text = PS.Player2name;
30.                 iTween.ScaleTo(Player2Container, iTween.Hash("x", 4.0f, "y", 4.0f, "time", 1));
31.                 GetComponent<AudioSource>().PlayOneShot(NameAppear);
32.                 await Task.Delay(5000);
33.                 RolltheDiceBox.SetActive(true);
34.                 iTween.MoveTo(MessageBox, EndPanel.transform.position, 3.0f);
35.                 await Task.Delay(3500);
36.                 MessageBox.SetActive(false);
37.                
38.                
39.             }
40.         }

 

I should have added that in development, the game works perfect

 

WebGL has no multithreading support. Task.Delay() won't work.

Would that function

DelayAsync

work for you as a replacement for Task.Delay?

 

Use UniTask
