I am unable to replicate the issue... could you please add the Javascript console output that you are seeing?

It is running and starting (it gets to the Press ENTER prompt, then gets these errors

connecting to server Connecting to server Request failed with status 400, sign_in_required Request failed with status 400, sign_in_required

I keep getting the too many rooms created message, then this appears on the JS console (it maybe some permission but I even tried to disable the firewall and same error appears), I am running the IDE as admin.

If I try same project with previous version, game may throw that message but will start

which version of the IDE / Runtime are you building with?

which version of the IDE / Runtime are you building with?

I have the issue with the current BETA 2023.1100.0.435 runtime 2023.1000.0.448

The version I've use where the project is unning-working is the current monthly

IDE 2023.8.2.108 runtime 2023.8.2.152

[rwkay]

@YYDan can you please get someone else to try this before we release the monthly build?

[YYDan]

Several of us reproduced, so I have updated the description and repro steps now,

@rwkay The missing step as to why you got that error different to the user was that GX requires you to log in on the website before you can test rollback. (The error shown is not especially informative and looks like an issue with the project, when it is not.)

@allende Have you found any work-around to fix this issue?

Hi, no I think they even disable rollback system on the monthly release

So they are probably working on a fix for this, the only work around would I can think about would it be to use the latest version where the issue was not present.

[ezekiel-hls]

Thanks for the reply. I will try using older monthly release version and see if I can make it work. Tried working on beta release 2023.800.x, that fixes the javascript exception but "rollback_game_running" never gets set to true

I was going through the official multi-player tutorial, and had only done the first coding step for obj_game. When I ran the game (target system GX.Games | GMS2 VM) I get this error as soon as the code loaded in the browser:

############################################################################################ ERROR in action number 1 of Create Event for object obj_game:

Variable .rollabck_join_game(100005, -2147483648) not set before reading it. at gml_Object_obj_game_Create_0 (line 5) - if (!rollabck_join_game()) { ############################################################################################ gml_Object_obj_game_Create_0 (line 5)

I have no idea what's happening, I can't find documentation for this error anywhere.

Rollback is always disabled in Monthly releases - this has always been the way and is documented in the manual as such.

You need to use a Beta version of GM if you want to use rollback in your games.
