This environment is developed in Python 3.6 and uses the library gym.
You can design a new map by editing/adding a file in the folder gridenvs/examples.
The variable init_map allows you to create a map with characters W, ., H, K, D which design respectively Wall, empty space, Hero, Key and Door.
You can change the parameters of variable state_dict which:
- first parameter is an integer which refers to the state of the world (for example : 0 -> The agent has not the key and 1 -> The agent has the key),
- second parameter is an integer which corresponds to the reward the agent gets when hitting the object,
- third parameter is a boolean. When it is True the episode ends when the agent gets the object and does not otherwise.
Also, you can just run the file keyboard_agent.py located in the root of the folder to generate the environment and move an agent with the arrows of your keyboard (press Escape to exit).
