MineLand is a multi-agent Minecraft simulator with large-scale interactions, limited multimodal senses and physical needs, all contribute to more ecological and nuanced collective behaviors. MineLand simulator supports up to 48 agents with limited visual, auditory, and environmental awareness, forcing them to actively communicate and collaborate to fulfill physical needs like food and resources. This fosters dynamic and valid multi-agent interactions. We also designed an AI Agent based on MineLand - Alex, inspired by multitasking theory, enabling agents to handle intricate coordination and scheduling.

You can check our paper for further understanding, and MineLand and Alex code is provided in this repo.

1. Installation

You can refer to the Installation Docs and Q&A for more detailed installation guidelines.

1.1 Prerequisites

MineLand requires Python 3.11, Node.js 18.18.0 and Java 17

1.2 Installation

We highly recommend installing MineLand in a virtual environment (such as Anaconda)

git clone git@github.com:cocacola-lab/MineLand.git
cd MineLand

pip install -e .

cd mineland/sim/mineflayer
npm ci
# If you use pnpm, you can use `pnpm install` instead of `npm ci`
# npm ci will install the dependencies from the package-lock.json file, while npm install will resolve the dependencies from the package.json file.

1.3 Verification

cd scripts
python validate_install_simulator.py

You will see Validation passed! The simulator is installed correctly., if MineLand simulator installed properly.

2. Quick Start

MineLand provides a set of Gym-style interfaces, similar to other simulators like MineDojo. The following is a minimal example code.

import mineland

mland = mineland.make(
    task_id="survival_0.01_days",
    agents_count = 2,
)

obs = mland.reset()

for i in range(5000):
    act = mineland.Action.no_op(len(obs))
    obs, code_info, event, done, task_info = mland.step(action=act)
    if done: break

mland.close()

You can refer to MineLand Docs or the code under the ./scripts directory for development.

MineLand does NOT have a minecraft game client for higher efficiency. You can obtain the current visual information of the agents from obs, or connect to the server using a vanilla Minecraft 1.19 client. The server operates locally with the default port, which means you can directly connect to localhost:25565 in the game to enter the server.
