Code Example
The most basic way to create a Griddly Gym Environment. Defaults to level 0 and SPRITE_2D rendering.
import gym
import griddly
if __name__ == '__main__':
env = gym.make('GDY-Zelda-Sequential-v0')
env.reset()
# Replace with your own control algorithm!
for s in range(1000):
obs, reward, done, info = env.step(env.action_space.sample())
env.render() # Renders the environment from the perspective of a single player
env.render(observer='global') # Renders the entire environment
if done:
env.reset()
