Features

• Automatic shearing of nearby sheep
• Auto eat
• Automatic shear crafting and wool depositing
• Auto queueing and auto reconnect
• Integrated proxy to connect into the game as the bot account
• Web inventory viewer
• Web world viewer

Installation

• INV= true|false. Optional. Set if the browser inventory viewer should be used. Default to true.
• START_IDLE= true|false. Optional. Start in mode idle or start in mode running. Default to false.
• CONNECT_ON= number|string. Optional. Unix timestamp in milliseconds or a string. This will query the 2b2t queue length and try to connect to the queue so that it will join on the given time. Usefull if you just want to use the bot as a queue waiting bot. See below for config options.

Usage

Starting

After starting the bot with npm run start it will create it's own proxy server running on port 25566. You can join the proxy server with localhost:25566 and see the bot working. When you run this script on a server you can also connect to the proxy by using the server ip and port 25566. When running a docker container make sure to expose port 0.0.0.0:25566 on the host machine to be able to connect from outside off the network. Example: -p 0.0.0.0:25566:25566 exposes port 25566 on all addresses when launching a container. Without this the docker container will only expose the port on the address range off 127.0.0.0 making it inaccessible from outside off the machine.

In game usage

To take control off the proxy bot type $link in chat. To unlink type $unlink in chat. The proxy implementation is not perfect. Entity states are not transferred correctly so map's and entities within render distance when joining the proxy will look wrong until you reload them. If the START_IDLE variable is set the bot will try to not get kicked when joining the server. Altho this does not seam to be too effective at the moment. While running in sheering mode the bot can stay connect for up to 9 hours before getting kicked by the server.

In game commands

• $link - Takes control of the bot. After this command you can use the bot as if you where connect to the server yourself.
• $unlink - Unlinks you if you are controlling the bot. Do this if you want the bot to continue working or simply disconnect.
• $deposit - Makes the bot deposit its wool into nearby chests immediately. Will only work if no player is currently linked to the bot.
• $stop - Makes the bot stop sheering
• $start - Makes the bot start sheering when it is stopped
• $quit or $exit - Makes the bot disconnect from the server
• $status - Gives some status information about the bot
• $help - Lists of all commands
• $config
  • autologoff Controlls if the bot should disconnect after the last player leaves the proxy. Default is off
    • on the bot will disconnect when the last player on the proxy disconnects.
    • off the bot will stay online even if players disconnect

CONNECT_ON environment variable

Waits and tries to join the queue at a time where it will reach the end by the specified time. This will query the queue length by pinging the 2b2t server and reading the listet player count in the motd. The value can be either one off:

• Unix timestamp in the node.js format. (milliseconds resolution)
• MM-DDTHH:mm - Next Month, date, hour, minute as off local time
• DDTHH - Next Date and hour as off local time
• DDTHH:mm - Next Date, hour and minute as off local time
• +HH:mm - Offset as hour and minute in the future
• +DD:HH:mm Offset as day, hour and minute in the future
