|

|

Just call this proton launcher script with your app as the only argument
|
||||
to run it with the default prefix
|
||||
${_pfx}/${_appid} and default mode "${_mode}".
|
||||
|
||||
Use other invocations as stated with USAGE: and/or modify behavior with
|
||||
environment variables as described below.
|
||||
|
||||
_mode_
|
||||
|
||||
You can change the mode of operation by specifying it as the first argument.
|
||||
Possible values are: waitforexitandrun, run, getcompatpath, getnativepath
|
||||
|
||||
_appid_
|
||||
|
||||
Protonfixes (included by proton-ge) uses three environment variables to
|
||||
determine the application to run fixes for.
|
||||
The env STEAM_COMPAT_DATA_PATH points to the wine prefix and usually includes
|
||||
the AppId, which is used in that case. If the env SteamAppId (or SteamGameId)
|
||||
is set, it takes precedence as the AppId used by protonfixes.
|
||||
|
||||
As proton itself needs the env STEAM_COMPAT_DATA_PATH set, the default prefix
|
||||
${_pfx}/${_appid} is used when it is not set or empty.
|
||||
In that case, an AppId given by env SteamAppId or as the first argument will
|
||||
alter this path accordingly.
|
||||
If STEAM_COMPAT_DATA_PATH is set, it will not be modified by a provided AppId.
|
||||
|
||||
Provide "appid" as the first argument to change the AppId regardless of
|
||||
the env vars (force). In this case, the mode defaults to "${_mode}".
|
||||
Useable for "appid": see https://steamdb.info/apps/
|
||||
|
||||
_other_
|
||||
|
||||
The env STEAM_COMPAT_CLIENT_INSTALL_PATH is set to "${_steam}" if not given,
|
||||
because proton cares. It has no effect if proton is not started from
|
||||
within steam anyway, therefore the path does not have to be actually resolvable.
|
||||
|
||||
DXVK creates cache files right next to the executable if the env
|
||||
DXVK_STATE_CACHE_PATH is missing.
|
||||
This launcher sets it to "${_cachepath}"
|
||||
if not provided. It makes sharing of those files as well as read-only game
|
||||
folders possible. Also, the cache survives remove/reinstall of the game.
|
||||
|
||||
You may share oder download caches for example from here:
|
||||
https://github.com/begin-theadventure/dxvk-caches/
|
||||
|
||||
Note that the env SteamGameId is not set by this launcher script in any case.
|
||||
This env is evaluated by steam executables inside the prefix. Set it yourself
|
||||
if you see fit.
|
||||
|
||||
To print the current env when this script is called, use the "-e" switch.
|
||||
|
||||
