BuildStatus PackageVersion Stable Format License


3D connectX repository, developed for the OpenAI Gym format.


The preferred installation of 3d-connectX-env is from pip:

pip install 3d-connectX-env



import gym_3d_connectX
import gym

env = gym.make('3d-connectX-v0')

env.utils.win_reward = 100
env.utils.draw_penalty = 50
env.utils.lose_penalty = 100
env.utils.could_locate_reward = 10
env.utils.couldnt_locate_penalty = 10
env.utils.time_penalty = 1
env.player = 1
actions = [0, 0, 1, 1, 2, 2, 4, 4, 0, 0, 1, 1, 2, 2, 0, 3]

for action in actions:
    obs, reward, done, info = env.step(action)
