Multi-agent extension? about minigrid HOT 3 CLOSED

Here you go ;)

MiniGrid distinguishes between the agent and the other objects in the environment, and in retrospect I think that this may have been a design mistake. I think that a better design choice would be to treat agents like other objects in the world, using the same class hierarchy, and maybe to keep a list of agents in the MiniGrid class. Then in the step method you may want to specify which agent you are stepping. In general, I feel like OpenAI Gym kind of assumes a single agent setup though.

Not sure we should make this refactoring to MiniGrid itself because I'm concerned about breaking existing code. It's unfortunate because there are a few things I would change if this wasn't an issue. The best solution may be for you to fork this repo and make the modifications you want. Maybe call it something like MultiGrid ;)

@ArnaudFickinger Nice work, many people have been asking for this.

Just one nitpick: since you based your environment on MiniGrid, you should copy over the open source license: https://github.com/maximecb/gym-minigrid/blob/master/LICENSE
