How to specify command line arguments when executing via flatpak in terminal?

I'm trying to execute the following command:

flatpak run com.heroicgameslauncher.hgl heroic://launch/1207658691 --no-gui --no-sandbox dm-phobos2?Game=QPro.LeagueMatch?NumBots=6?SpectatorOnly=1?DMTeam=XGame.DMRosterConfigured?Mutator=XWeapons.MutNoSuperWeapon,XGame.MutSlomoDeath?TimeLimit=4?GoalScore=0

flatpak run com.heroicgameslauncher.hgl heroic://launch/1207658691 --no-gui --no-sandbox dm-phobos2?Game=QPro.LeagueMatch?NumBots=6?SpectatorOnly=1?DMTeam=XGame.DMRosterConfigured?Mutator=XWeapons.MutNoSuperWeapon,XGame.MutSlomoDeath?TimeLimit=4?GoalScore=0

flatpak run com.heroicgameslauncher.hgl heroic://launch/1207658691 --no-gui --no-sandbox dm-phobos2?Game=QPro.LeagueMatch?NumBots=6?SpectatorOnly=1?DMTeam=XGame.DMRosterConfigured?Mutator=XWeapons.MutNoSuperWeapon,XGame.MutSlomoDeath?TimeLimit=4?GoalScore=0

flatpak run com.heroicgameslauncher.hgl heroic://launch/1207658691 --no-gui --no-sandbox dm-phobos2?Game=QPro.LeagueMatch?NumBots=6?SpectatorOnly=1?DMTeam=XGame.DMRosterConfigured?Mutator=XWeapons.MutNoSuperWeapon,XGame.MutSlomoDeath?TimeLimit=4?GoalScore=0

This is in an attempt to execute UT2004 via Heroic via Flatpak, with additional command line arguments I'm hoping to pass to UT2004.exe. I pulled the base command from the Steam Non-Steam Game entry added by Boilr.

The game launches fine, but the command line argument I'm providing is ignored. Please help.

you can provide those arguments in game settings

radical-lime•6/21/23, 8:28 PM

other than that heroic does not forward them to the game

Ok thanks. Would there be a way to script that, e.g. a config file I could automatically adjust before executing?

radical-lime•6/21/23, 10:34 PM

you could modify the config of the game directly (it's in .config/heroic/)

Thanks, I'll have a look. I'm trying to build a custom launcher, but if there's a text file I can edit then that's good enough for me

Sorry I can't find any .config/heroic.config/heroic on steam deck, I'm guessing you meant ~/.config/heroic~/.config/heroic? But there's no such file in ~/.config/~/.config/ folder

slow-yellowOP•6/22/23, 8:54 AM

do I need to perform some action in Heroic UI to generate the config file?

radical-lime•6/22/23, 8:57 AM

ah steamdeck

radical-lime•6/22/23, 8:57 AM

~/.var/app/com.heroicgameslauncher.hgl/config/heroic

slow-yellowOP•6/22/23, 8:58 AM

ahh found it at /home/deck/.var/app/com.heroicgameslauncher.hgl/config/heroic/GamesConfig/1207658691.json/home/deck/.var/app/com.heroicgameslauncher.hgl/config/heroic/GamesConfig/1207658691.json thanks!
