mc-installer installs and runs the Minecraft Launcher inside of a Snap. Minecraft itself uses the
.minecraft directory for game data such as savegames and mods. Many users expect their savegames and mods to be in that folder and are surprised when that’s not the case. They are also surprised that the Minecraft Snap doesn’t find the savegames in that folder. It’s common for users to manually copy their savegames to that folder when they get a new computer, for example. Given that many users spend hundreds of hours building their own worlds in Minecraft, those savegames are very important.
I’d like to request auto-connection for read and write permissions to that folder.
dot-minecraft: interface: personal-files write: - $HOME/.minecraft/`
This should not provide any conflicts when multiple versions of Minecraft are installed because Minecraft supports this internally. Even without Snaps, it’s common and supported to have multiple Minecraft versions installed. The official Minecraft launcher allows you to download and install multiple different versions of Minecraft at the same time. The game itself warns you when opening an incompatible save file and gives users the option to migrate save data from one Minecraft version to the next.
Note: In case this influences the decision; mc-installer is an unofficial snap not affiliated nor endorsed by the Minecraft team. The binaries run in this snap, however, are the regular unmodified Minecraft binaries.
