LZSplitDoom

[Sliver-X]

I've updated this to v1.1, which is mostly technical fixes as well as proper NERVE.WAD support.

Windows only: Won't work even under Wine due to WinAPI calls used for window handling, but it should run on any PC/Server version of Windows from XP to 11 without issues.

Sad, I really wanted to give this a shot in Artix, but oh well. Hope this project grows up :'>

[Sliver-X]

I've put out what I hope is the final version, v1.2.

 

See the initial post for changes and the download link.

 

Thank you to everyone who gave me bug reports.

[SyntherAugustus]

This is so great! Thanks for taking the time to doing this.

 

If it all possible can we define the data directories for iwads and pwads in the future? I don't mind duplicating my wads for this, but I have everything already organized for another launcher.

You're welcome, I'm glad others are finding it useful.

 

I'll add a tab for configuration like that if I ever continue working on it, but for the time being, you can manually edit these sections in %APPDATA%\LZSplitDoom\player1.ini:

 

[IWADSearch.Directories]

[FileSearch.Directories]

 

The first line under each is always updated to the path of the DATA folder located in the launcher directory when a game is ran, but any lines below it aren't touched and will be persistent unless the INI file is deleted.

 

You can also invoke the launcher purely from a command line, so you could theoretically chain to it from other launchers, like:

 

"C:\Program Files\LZSplitDoom_v1.2\LZSplitDoom64.exe" -split=vertical -iwad D:\DOOMWADS\doom2.wad -file D:\DOOMMODS\brutaldoom.pk3

Cleaned up some of the latest G-Force spamming. He got a warning for this posting (and not-reading) style but seems to have ignored it, and added in a bit of trolling, so that's now a one-month tempban.

[Sliver-X]

I've been working on this for a few days and basically ended up rewriting most of the launcher: It should be a much better program now in all regards.

 

It now supports Strife (DM only: The Strife CoOp mod requires a newer GZDoom codebase than what LZDoom is built on), save game loading, the ability to define the WAD folder it searches for things and a bunch of other small fixes to the GUI.

 

The original post has been updated with a download link.

i tried your source port it's cool... but theres some problems 

both keyboard and controller control player 1 not player 2 

also when i go to click on player 2's screen to try and config some sort of controls player 1's screen freezes 

and other way around 

smaller problem the weapon sprites are really small why?

any way to fix these things ?

[Sliver-X]

Hi G-Force: Aside from the really low effort sockpuppet account name differences, you used PengOil when posting to my Youtube channel recently and after looking at your post history here it's obvious who you are.

 

This isn't a source port, rather a highly specific front end to one. I am bound by the limitations of LZDoom for a lot of this.

 

I'll say it again: Read the Readme.txt file I made for this. If you had done that, or even bothered to read the direct answers I gave you in this thread already, you'd know Question 1 is stepping outside how this setup works (It's doable, but would require manual INI editing to pull off which I'm not going to go into), and that Question 2 is irrelevant since no changes made in P2-P4's running instances will survive on next run.

 

Question 3 is an FOV problem with whatever resolution the instances are being split into on your primary display, so you need to adjust the FOV in P1's menu/config file to compensate. Or you could even change how the engine does scaling entirely from within P1's config.

2)  Added Strife Coop support.
3)  Added Square's Adventure and Harmony.
4)  Greatly expanded Readme.
5)  Code cleanups/optimizations.
6)  Restructured config/save logic.
7)  Fixed typos.
8)  Added documentation for bundled games.

 

Updated source code is included.

you have no idea, i no longer have to use the unity port for splitscreen, this is a blessing

[Sliver-X]

I'm glad people are finding it useful. Please let me know if you run into any problems with it and I'll fix it ASAP: I've used it to go through dozens of Doom mods and most of the original idTech 1 games with my son since I made it and haven't run into anything yet, but you never know.

personally i just want 3 player support, so there isn't one player left inactive

[PITTSBURGH PENGUINS]

Hey Sliver X , your thing has a problem , I can't use Cheat codes :( No matter what I do no matter what parameters I put in I can not use any single cheat code ...

Is there any way I can ?

[Arrowhead]

I just wanted to say thanks!

 

This program is just what I was looking for. It is a lot of fun to be able to play DM/co-op this easily w/ my brother. Had a slightly hard time adding custom maps at first, but I figured it out. The GUI looks great, btw!

 

Great work.  :)

 

 

[Sliver-X]

You're welcome. Please let me know if you find any bugs/etc, or even just have general questions about its usage.

Doom 64 Retribution

Oh wow I'll let the likes of @Nevander, @Immorpher, @Jetx_121, and others know about this! We D64 folks would like to have more multiplayer chances, and this looks like a very pleasing one to test.

[Sliver-X]

Doom 64 - Retribution has no DM starts defined, so it's co-op only unfortunately.

 

The GUI will disabe the COOP/DM selector after setting it to COOP when D64 is selected but you can try forcing it with the -deathmatch switch and it'll just crash outright due to this.

Woah it can load in soundfonts? We've been dreaming about this for GZDoom for a while (since D64 uses a custom one).

Maybe it could do multiplayer with this multiplayer fork of retribution? http://sfjake.infinityfreeapp.com/doom64.html?i=1

[Sliver-X]

Yeah, the FluidSynth MIDI engine supports SF2 patch sets. I named Retribution's SF2 file to DOOMSND.SF2 (The default one that comes with LZDoom) and the launcher edits [SoundfontSearch.Directories] in the config at runtime to point to where this resides, and reverts it to normal for any other game.

 

Thanks for the link: I'm actually using LZSplitDoom to go through Doom 64 with my kid right now, so I'll be checking it out after I post this. If I can get Doom 64 DM support working as expected I'll update the program.

Is DOOM CE compatible with LZDoom? That's better than Retribution if so.

Heya Silver,  Is there a specific launcher you have been able to successfully chain launch it from? 

 

The couple I have tried don't allow me to put the -split parameter at the front off the command so it doesn't see it.  If I try to create a .bat with the -split defined, then user the launcher for the rest other -iwad and -file parameters fed from the launchers don't seem to make it through.

 

How have you done it?

In case you didn't know, you can use %* in a batch file to insert all the arguments passed to it, e.g. from your launcher.

I did not know that but tossing that into my batches worked perfectly.  Thanks a ton Shepardus!

we can always port/make DM maps ourselves

typo issue

[Faceman2000]

Sorry for the bump! This is awesome and my brothers and I have had a lot of fun with it. Is there a command line code to set ammo and items to respawn when playing coop?

[Sliver-X]

Adding +sv_itemrespawn 1 to the command line may work? I can't test it currently, but I seem to recall using that with ZDoom back in the day, at least.
