OpenAI Gym Environment for 2048
Project description
This package implements the classic grid game 2048 for OpenAI gym environment.
Install
pip install gym-2048
Environment(s)
The package currently contains two environments
Tiny2048-v0: A 2 x 2 grid game.
2048-v0: The standard 4 x 4 grid game.
Attributes
Observation: All observations are n x n numpy arrays representing the grid. The array is 0 for empty locations and numbered 2, 4, 8, ... wherever the tiles are placed.
- Actions: There are four actions defined by integers.
LEFT = 0
UP = 1
RIGHT = 2
DOWN = 3
Reward: Reward is the total score obtained by merging any potential tiles for a given action. Score obtained by merging two tiles is simply the sum of values of those two tiles.
Rendering
Currently only basic print rendering (mode='human') is supported. Graphic rendering support is coming soon.
Usage
Here is a sample rollout of the game which follows the same API as OpenAI gym.Env.
import gym_2048
import gym
if __name__ == '__main__':
env = gym.make('2048-v0')
env.render()
done = False
while not done:
action = env.action_space.sample()
next_state, reward, done, _ = env.step(action)
env.render()
