GTAV doesn't launch #2

Closed jaydenmilne closed 4 years ago

jaydenmilne commented 4 years ago

GTAV doesn't launch because apparently some authentication needs to happen through the EGL before it will work, verified by looking at the command line arguments that invoke PlayGTAV.exe, there are some tokens passed in from the EGL.

It seems that we can work around this by using the URI format that the Epic Games Launcher uses when you make a shortcut (Library -> 3 dot menu -> create shortcut)

Instead of the target being

D:\Epic Games\GTAV\PlayGTAV.exe

it should be

com.epicgames.launcher://apps/9d2d0eb64d5c44529cece33fe2a46482?action=launch&silent=true

Where 9d2d0.... is the AppName field of the .item file (see https://jayd.ml/games/2020/05/16/epic-games-store-steam-libraries.html)

We're already collecting the AppName (I figured it would be useful) so we should change the link format we inject into shortcuts.vdf. That will break the picture previews in steam coming from the .exe though, which would be sad.

Good news: If we give Steam the path to the executable as the icon path, it will load them from the .exe! 🎉🎉🎉

Fixed in 0.2.0
