GZDoom v4.13.2 / loading DoomII coop save with 3 players causes player mismatch

[erictoast]

Really was looking forward to 3 players doom coop, using GZDoom v4.13.2, all players have the default options, when loading from a save all players have Out of Sync error, some players seemingly stood on the walls sideways.

GZDoom v4.13.2
Doom2
Default options
Start 3 player coop, save the game and quit
Load the savegame, have all players join
It will go out of sync

2 player coop game is fine it plays really good and the savepoints work on 2 players but 3 players is impossible for us, tried older Gzdoom variants and it seems to be worse, on older variants the host cannot move the mouse cursor when they wait for players and the mouse cursor is stuck on the screen when the game starts.

The 3 player coop game starts fine, but we can't load a savepoint without the Out of Sync error.

Joining a Doom2 savepoint with 3 players, the host never has the player switched but player 2 and 3 sometimes switch when joining.

Default options
Start 3 player coop, save the game and quit
Load the savegame, have all players join
Player 2 and 3 will be switched around

The only workaround was myself and player 3 to join the host at the same time, then we had our correct players.

This one is probably already fixed, there have been a lot of net improvements since 4.13.2's release. You can try https://devbuilds.drdteam.org/gzdoom/ for the nightly builds.

Good stuff, I'll tell the boys doom coop is back! Any issues I will post here on the same thread.

Any issues I will post here on the same thread.

Any issues should be posted to separate threads, one per issue. The developers cannot track issues in combo threads so they often just get ignored.

For what it's worth, the guy who's been doing multiplayer stuff still makes submissions in short bursts and recently had a slew of them approved and still seems to be submitting more. So it might be worth checking for new dev builds every now and again even after today.

Its still not working, loading up a 3player save on Doom2 players has out of sync error.

Player2 and Player3 swap places when joining.

If any player makes a mistake example loading up the wrong save when they join, all other clients have a black screen and you cant exit, you have to crtl,alt,delete to end gzdoom process.

It never has out of sync error when you start a 3player game, the problems are the saves.
