ToriLLE

Toribash Learning Environment. Extra "L" to make words more memorable for Finns ("Torille" = "To the marketplace").

ToriLLE provides learning agents an interface to video-game Toribash, a humanoid fighting game. Toribash provides environment for MuJoCo-like humanoid control, specifically aimed for competitive gameplay. This makes ToriLLE suitable for e.g. self-play experiments.

ToriLLE comes with a Python interface and pre-made OpenAI Gym environment with various tasks. Following white-paper includes baseline experiments and benchmarks conducted using ToriLLE: https://arxiv.org/abs/1807.10110

Requirements

Tested to work on Windows 10, Ubuntu 16.04 and MacOS 10.13. Tested on Python versions 3.5 and 3.6, and will likely not work on 2.7.

• Numpy (Python)
• FileLock (Python)
• Wine (For Linux/MacOS. Requires modern version. Tested on 3.0.3)

Quickstart

Remember to install Wine if you are on Linux or MacOS. Make sure wine command is defined.

Following will download ToriLLE with stripped down version of Toribash:

pip install torille

Random agent:

from torille import ToribashControl
from torille.utils import create_random_actions

# Show gameplay
toribash = ToribashControl(draw_game=True)
toribash.init()

# Random agent
while 1:
    state, t = toribash.get_state()
    if t: break
    toribash.make_actions(create_random_actions())
toribash.close()

OpenAI Gym environment:

import gym
import torille.envs

env = gym.make("Toribash-DestroyUke-v0")
# Show gameplay
env.set_draw_game(True)

initial_state = env.reset()
t = False
# Random agent
while not t:
    s, r, t, _ = env.step(env.action_space.sample())
env.close()

Manual installation

You can install ToriLLE without PyPI/pip with the following:

• Install Toribash (note: Only Steam version may be up to date)
• Copy contents of toribash-codes to Toribash installation directory. Overwrite files
  • Note: This will prevent using that specific installation as a regular game. Remove/rename profile.tbs file to revert most of the changes and use game normally again.
  • Note2: Starting with Toribash 5.4 / Steam version of Toribash, settings file is stored in under user's directory at Saved Games/Toribash/custom.cfg. Toribash loads this file by default if it finds it, which may cause ToriLLE to run in wrong settings.
• Provide path the installed toribash.exe when creating ToribashControl objects (if you use provided Python library)

Playing in multiplayer

Note: Multiplayer does not work on Linux Wine!

Want to try your agents against human players in multiplayer? Check how manual remote control works.

Documentation

Examples in examples provide quickstart to how to use ToriLLE, and also show how to apply settings or record replays.

For troubleshooting, see the FAQ.

If you wish to modify ToriLLE or use other language to control Toribash instance, see hacking and documentation on protocol.
