⚠️ This project is now archived. For the same and even better features take a look at HeadlessMc and the HeadlessMc-Specifics.
While headless Minecraft Clients aren't anything new, they come with a drawback. The Minecraft API is missing and you need to add all functionality yourself. That means getting mods like Baritone which are tightly coupled with mojangs code to run is a pain. HeadlessForge takes the other way around to create a Minecraft Console Client: It removes all functionality which prevents you from running Minecraft on the console (lwjgl) from Minecraft and adds a command interface.
HeadlessForge is written in kotlin, the Mixins in java. It's currently targetting version 1.12.2 of Minecraft.
Start a command with . to send a chat message while ingame. Use ./ or just
/ to use Minecraft commands. Anything else will try to execute one
of the following commands:
-quit to quit Minecraft.
-help to get help with HeadlessForge commands.
-gui to output the currently opened gui. This will give you ids to use with:
-click <id> allows you to click a GuiButton.
-text <id> <text> allows you set the text of a Textfield.
-connect <ip> connect to a server.
-disconnect disconnect if you are connected to a server.
-ram outputs info about the current memory usage.
-session output info about the current Minecraft Session.
-tictactoe well...
Java 8 and MinecraftForge-1.12.2-14.23.5.2854 are required. Drag the
HeadlessForge jar into the mods folder in the .minecraft folder. Then enter
java -jar <headlessforge.jar name> <Path to .minecraft folder> on the console.
On windows the path should look like this: C:\Users\<user>\AppData\Roaming\.minecraft.
Of course HeadlessForge doesn't support entering account credentials outside the official Minecraft Launcher, so you won't be able to play. When launching HeadlessForge from the commandline you can also specify the folder containing the lwjgl64 binaries. I wouldn't recommend running this with any paid applications that don't like to get cracked, because a different method will be at the top of the stacktrace. HeadlessForge is a work in progress and there's probably lwjgl context that I missed, so expect crashes. It's also stable enough for my purposes so don't expect too much support.
