About

ATLauncher is a launcher for Minecraft which integrates multiple different modpacks to allow you to download and install modpacks easily and quickly. ATLauncher has a few nice features including: Below is the steps to run this flatpak in a custom directory - Allows quick and easy install of modpacks, no more messing around trying to install mods - A range of different packs, and more being added all the time - Multiple instances. Install a pack as many times as you like without messing up a previous install - Multiple accounts allow you to login as different users from the one install - Private instances. This allows you to only install instances under your account so people can't mess up your worlds - 1 click backup of your saves - Easy server creation from within the Launcher - Install packs from CurseForge and FTB - Mod management for instances, including auto download and installation of mods, maps and resource packs from CurseForge and Modrinth - Support for both Mojang and Microsoft accounts - More features always being added - Open Flatseal - Select ATLauncher on the left - Scroll down to "Filesystem", "Other files" - Add a new entry via the icon with a "folder" and "plus" sign - Input the path you want to let ATLauncher run in. IE `/home/name/Games/ATLauncher` - Scroll down to "Environment", "Variables" - Click the "plus" sign to add a new entry - Write down an enviroment variable, IE `CUSTOM_DIR=/home/name/Games/ATLauncher` - Run ATLauncher - Notice that ATLauncher is now working using CUSTOM_DIR
