[Solved] Running a shell script before launching a game and after exiting that game

I thought it will be easy to do that as there's already options for both (launch & exit). But I cant get it to work. I wanna use ludusavi which was installed using flatpak. Ludusavi already had a guide for heroic but I cant get it to work so I was thinking about creating my own script. Heroic is installed as native package. Distro: Fedora 42 KDE

I am trying to use this. right now running ludusavi-wrapper.sh backup "Assassins Creed IV Black Flag" in terminal works and the script exit with 0 but if I put this in "Select a script to run before the game is launched" then its stucked in launching state I would also like to get the game name from heroic if thats possible when I run heroic via cli i found this when launching the game

Error occurred in handler for 'launch': spawn ~/games/.tools/ludusavi-wrapper.sh backup "Assassins Creed IV Black Flag" ENOENT

I did added path and heroic should have access to this

Error occurred in handler for 'launch': spawn flatpak run com.github.mtkennerly.ludusavi --config $HOME/.var/app/com.github.mtkennerly.ludusavi/config/ludusavi backup --force "Assassins Creed IV Black Flag" ENOENT

if I just add the command

CommandMC•2mo ago

You can't run a Flatpak from another Flatpak Add flatpak-spawn --host to the start of your command to execute the command on the host instead. Note that this requires the org.freedesktop.Flatpak talk and essentially disables the advantages of Flatpak To grant that talk permission, run

flatpak --user override --talk-name=org.freedesktop.Flatpak com.heroicgameslauncher.hgl

flatpak --user override --talk-name=org.freedesktop.Flatpak com.heroicgameslauncher.hgl

Heroic isnt installed as flatpak

CommandMC•2mo ago

Oh sorry, missed that note. I only read "I did added path and heroic should have access to this" and figured Flatpak I assume the script you created is executable?

like-goldOP•2mo ago

yep I tested manually before adding and looks like backup portion is working as I haven't tested restore yet

CommandMC•2mo ago

Looking at the code, I don't think scripts can have parameters You should be able to do this though: https://github.com/mtkennerly/ludusavi/blob/master/docs/help/game-launch-wrapping.md#heroic (perhaps with slight changes since you're using the Flatpak Ludusavi)

like-goldOP•2mo ago

Sorry I am new to scripting dont know much as I said I was able to get it work when I ran it. I created another post too https://discord.com/channels/812703221789097985/1394735173282697236/1394735173282697236 this didnt explain much and idk how to add this wrapper. is it similar to adding script ?

CommandMC•2mo ago

Create the file as instructed there, replacing ludusavi with flatpak run com.github.mtkennerly.ludusavi since you're on Flatpak Then add that script as a wrapper in Heroic ("Wrapper command" in the "Advanced" tab of the game settings)

like-goldOP•2mo ago

I assume

$!/bin/sh
ludusavi --config $HOME/.config/ludusavi wrap --gui --infer heroic -- "$@"

$!/bin/sh
ludusavi --config $HOME/.config/ludusavi wrap --gui --infer heroic -- "$@"

here ludusavi has to be changed to latpak run com.github.mtkennerly.ludusavi config dir to $HOME/.var/app/com.github.mtkennerly.ludusavi/config/ludusavi but I wasn't able to get it to work but let me try again

like-goldOP•2mo ago

does it look ok?

CommandMC•2mo ago

Just add the script as the wrapper, no arguments

Did as you said

CommandMC•2mo ago

Oh actually, I don't think you can use ~

like-goldOP•2mo ago

$HOME then ? lemme try

CommandMC•2mo ago

Assuming ~/.local/bin/test/ is on your PATH, you should be able to just add ludusavi-wrapper.sh No, you'd have to write out the actual path

like-goldOP•2mo ago

from /home/*?

CommandMC•2mo ago

/home/your_username/.local/bin/test/ludusavi-wrapper.sh, replacing your_username with your actual user's name

like-goldOP•2mo ago

yep tried now ludusavi can find the game

like-goldOP•2mo ago

if I say yes then I get crash notification BTW is it possible to get the game name from heroic ?

CommandMC•2mo ago

Yeah figured, Ludusavi's Flatpak doesn't include Wine dependencies... The easiest way to resolve this would probably be to just use the native Ludusavi

like-goldOP•2mo ago

Alright . But I have never tried building from source https://github.com/mtkennerly/ludusavi/releases/download/v0.29.1/ludusavi-v0.29.1-linux.tar.gz idk how to use this, using llm i got to know that I can use it as any other script. this one is just compiled . does it mean if I put it in my script folder I can run normally ? sorry for the noob question This doesn't say if its rpm or deb build

CommandMC•2mo ago

It isn't a package, it's simply an executable However depending on your distro, there might be a package for it in the official repos

like-goldOP•2mo ago

I tried looking for copr and rpmfusion and official there's none

CommandMC•2mo ago

Also, please do not use LLMs to attempt to get help here. They will lie to you

like-goldOP•2mo ago

yes thats why I didn't try using that file I just use those to get direction then try to do my research Whats the difference then ? similar to running script or installing something ?

CommandMC•2mo ago

Right, manual install it is then. Download the release (https://github.com/mtkennerly/ludusavi/releases/download/v0.29.1/ludusavi-v0.29.1-linux.tar.gz), then extract it and place the executable into ~/.local/bin/. Run a chmod +x ~/.local/bin/ludusavi to mark it as executable I assume ~/.local/bin is on your PATH. To check, open a terminal now and run which ludusavi. If that command finds it, you're good Open up your ludusavi-wrap.sh script and change it to match the contents of the guide again (replacing flatpak run ... with just ludusavi

like-goldOP•2mo ago

yep done that it looks like ludusavi still cant recognize the game. I did have this issue if name isn't same or what ludusavi expect when I was in windows. BTW is there a way to know what heroic launches ? in this way I can create an alias in ludusavi This time I was able to launch when I pressed yes

CommandMC•2mo ago

it looks like ludusavi still cant recognize the game. I did have this issue if name isn't same or what ludusavi expect when I was in windows.

Could you send in a game log?

BTW is there a way to know what heroic launches ? in this way I can create an alias in ludusavi

I'm not sure what you're asking there. Heroic will launch the game with either Legendary (for Epic Games), GOGDL (for GOG) or Nile (Amazon)

like-goldOP•2mo ago

Sorry IDK where the log is

HeroicBot•2mo ago

To help you, we need a game log. Please see the following images on how to get it.

like-goldOP•2mo ago

Now it looks like with the wrapper script I cant launch the game anymore. BTW this is a non heroic game. I had it installed in my old windows partition and copied over https://0x0.st/8djt.log

CommandMC•2mo ago

Sideloaded games probably won't work with Ludusavi. It doesn't have any metadata to find out the game you're playing

like-goldOP•2mo ago

Oh I see but dev suggested for emulators I can do it by adding custom games. BTW ig I should give it a try with my script earlier see if that works Thanks for your time But any idea why the script wont work that way ?
