Goal

Twofold:

1. A clone of the real client, with extra features.
2. A framework for easily writing bots in JavaScript.

The framework allows you to write complex bots in JavaScript with very little overhead. For example, echo_bot.js, who simply repeats everything you say, fits in less than 80 characters of code:

mf.onChat(function(username, message) { 
    mf.chat(message);
});

Progress:

• See examples of bots already written.

Source code

See mineflayer on GitHub.

Debugging echo_bot.js

As I step through the debugger, it runs this line of code which caused echo_bot to chat in Minecraft.

Lots of block types and metadata are rendered correctly.
