Instructions for Linux

[trusktr]

Hello, can you please provide instructions for how to run Doom 3 on Linux? The README and the Flatpak page both don't really have any good instructions.

Where do I get the file, where do I put them, etc?

When I launch Doom BFA, it says "failed to find the game's base path" with no further instructions:

Hi, if you are using the flatpak version the engine will search on some known file paths ( like /home/ or any path where usually either external storage device are mounted to or secondary internal ones) in order to find an installation of either DOOM 3 BFG Edition, DOOM 3 (2019) or DOOM BFA Classic Edition. If you have installed the game to a place that it can't find it, then consider moving it to another folder and tell me what was the previous path (maybe I didn't knew it).

From the other hand if you have download it from a known website (here on Github, ModDB, Nexus Mods, Game Banana) then the only thing you need to do is to just extract the files you downloaded to the game's folder.

Finally, keep in mind that DOOM BFA is a source port for DOOM 3 BFG Edition and it requires a legitimate copy of the game in order to work. Without it the source port can't do anything.

I was able to get the Dhewm 3 flatpak working, the instructions were easy: simply place the /base folder of the game in the specified location for dhewm3 (f.e. ~/.var/app/<dhewm3>/data/base).

Is there a specific place I can place the game's /base folder and it will work?

[trusktr]

Here's an example when first launching dhewm3, it specifies to place the base/ folder in a specific location, making things a little more obvious:

It doesn't work like that on BFA. (Not to mention the issues this approach brings in) BFA flatpak searches on the 3 following paths: your home folder, /run/media and /media. In case the game is installed by another flatpak app, you must provide at least read access to the ~/var/app folder of that app.

The search algorithm looks for the file _common.resources in order to determine the game's folder, in case this is not working you can try to launch it once with the launch argument +set fs_basepath "path to the game"

Hi there. I just updated the Engine code and now it should tell you to use the fs_basepath launch argument.
Right now it will only be available on the nightly builds.
When the new version release, the flatpak version will update too.
