melee-env

melee-env wraps the fantastic libmelee as a more gym-esque environment with less boilerplate and setup. Additionally, melee-env provides a convenient and highly flexible framework for creating your own agents. For more information on these topics and melee-env, see the README in the agents folder.

Code example:

from melee import enums
from melee_env.env import MeleeEnv
from melee_env.agents.basic import *
import argparse

players = [Rest(), NOOP(enums.Character.FOX)]

env = MeleeEnv('path/to/iso', players, fast_forward=True)

episodes = 10; reward = 0
env.start()

for episode in range(episodes):
    gamestate, done = env.setup(enums.Stage.BATTLEFIELD)
    while not done:
        for i in range(len(players)):
            players[i].act(gamestate)
        gamestate, done = env.step()

Video Demonstration

This library has been designed with flexibility in mind. The action space, observation space, and the agents are completely modular, and there are only a few requirements to build your own.

Note

This library requires Slippi, which in turn requires an SSBM 1.02 NTSC/PAL ISO. This library does not and will not distribute this. You must acquire this on your own!

Installation

Install from pip: pip install melee-env. Test by running agents_example.py --iso=/path/to/your/iso
