Brings LWJGL3 and modern Java versions to Minecraft 1.12.2. Bundles RetroFuturaBootstrap as a flexible early load plugin system. This is a 1.12.2 port of the 1.7.10 version of lwjgl3ify.
Lwjgl3ify depends on MixinBooter.
Compatibility
Though lwjgl3ify tries to be compatible, there will inevitably be mods that don't work with it. If you encounter a mod that doesn't work with lwjgl3ify, please report it on the issue tracker if someone hasn't already!
Configs
If you want to tweak your default window size, OpenGL context properties or other more advanced settings, check out the config file in config/lwjgl3ify.cfg after the first startup.
Server installation
First, install a working 1.12.2 Forge server, from a modpack zip or using forge's installer.
Then, install the mod jar (and mixinbooter) in mods/, and download the forgePatches jar. Put the forgePatches jar in the same folder as your forge-universal and minecraft server jars.
Thermos/Crucible/Hybrid servers are not supported!.
Lwjgl3ify also depends on MixinBooter.
Rename the forgePatches jar to just lwjgl3ify-forgePatches.jar. Create a file named java9args.txt with the contents of the file in this mod's sources.
You can now launch the server with a command like the following, assuming the first java executable on your PATH is java 11, 17, or newer:
java -Xmx6G -Xms6G @java9args.txt -jar lwjgl3ify-forgePatches.jar nogui
