This project provides a framework for collecting navigation trajectories in the Minecraft environment using Mineflayer. It supports controllable agents, path planning via A*Mineflayer-pathfinder, and image rendering Prismarine-viewer.

Certain code is modified from above projects to support features. Modified version is in LoopNav-mineflayer, LoopNav-pathfinder, LoopNav-prismarine-viewer.

See CHANGES.md for details.

• Loop-based navigation (A → B → A) or (A → B → C → A)
• Recording observation, action, position, Goal.
• only one action is allowed on one timestep
• avoid stuck by edge of blocks

git clone https://github.com/Kevin-lkw/LoopNav
cd LoopNav
npm install

for example, in liunx server

java -Xmx2G -Xms2G -jar server.jar nogui

python run.py --name Bot --target village --output_path ./output

--name: the name of the bot --target: the target to collect data, can be 'village', 'biome' or 'structure' --output_path: the path to save the collected data

there might be some illegal data(e.g. the agent is died in lava or loss connection with the server) we provide a script to process the data this script will delete the illegal data and count the number of trajectories for each target

python process.py --output_path ./output --target village

• tp command failed: give the Bot OP permission to use tp command
