Context + "jump"

bot.setControlState('jump', true)

User Commands

// (previous context)
// Go forward
bot.setControlState('forward', true);

Code – Codex

import mineflayer from "mineflayer";
import { context, callOpenAI, updateContext, eval } from "./core.js";

const bot = mineflayer.createBot({
  username: "OpenAI",
  host: "localhost",
  port: 56794,
});
  
bot.on("chat", async (username, input) => {
  if (username === bot.username) return;
  
  const previousContext = context();
  const response = await callOpenAI(input, previousContext);
  eval(code);
  updateContext(input, code);

});

Simple Context

  // Go forward
  bot.setControlState('forward', true);

  // Go back
  bot.setControlState('back', true);

  // jump
  bot.setControlState('jump', true);

  // Hi how are you ?
  bot.chat("I'm fine, thanks!");

  // What's your name ?
  bot.chat("My name is " + bot.username);
const STOP_WORD = "// ";
const EOL = "\n";
const openAIkey = process.env.CODEX_API_KEY;

const body = {
  prompt: context + STOP_WORD + input + EOL,
  max_tokens: 300,
  temperature: 0,
  stop: STOP_WORD,
  n: 1,
};

const response = await fetch("https://api.openai.com/v1/engines/davinci-codex/completions", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: `Bearer ${openAIkey}`,
  },
  body: JSON.stringify(body),
});

if (!response.ok) {
  error("api response failed with statis %s", response.statusText);
  return;
}

return await response.json();

Simple Context

Advanced Context

// Get bot's current position
bot.entity.position;

// Stop any movement
bot.clearControlStates();

// Come to me
findPlayer(bot, 2, target);

// Follow me 
goToPlayerInterval = setInterval(() => followPlayer(bot, 2, target), 1000);

// Stop following me
clearInterval(goToPlayerInterval);

// Get dirt
mineBlock(bot, "dirt", mcData);

// Get oak log
mineBlock(bot, "oak_log");

Advanced Context

Your turn to make it better!

Playing Minecraft with OpenAI & GPT-3

Playing Minecraft with OpenAI & GPT-3

There are players who play Minecraft for the pleasure of playing, others to develop their creativity. But there is another way to play Minecraft, and that is by using an artificial intelligence generated by GPT-3. In this presentation, we'll talk a bit about AI and ML, GPT-3, and Codex, but most of all, we'll have fun generating code to control a bot in Minecraft, all in a good mood! Are you tempted?
