Extending Support for Four Rooms about minigrid HOT 5 CLOSED

Ok, so these are the environments you want to define.

Some pointers:

• There is a wrapper to enable fully observable environments:
• There is a RoomGrid class that makes it easier to define environments that are NxN grids of rooms connected by doors, this may be helpful.

Otherwise, are there specific things you're not sure how to do?

Regarding your environments, things might be a little simpler if you stick to the actions defined by MiniGrid, where the agent rotates left/right instead of directly moving 4-ways, and if you directly use RoomGrid without colored rooms (use colored doors instead). Are you trying to recreate specific existing environments from some published paper?

Thank you for such a prompt response.

I am trying to create a simple environment with colored rooms and balls where the agent can take the above-mentioned actions. I am actually trying to get the baseline working as of now.

I see that there is a figure "fourroomqa-env.png" that is close to what I am trying to achieve. But I can't seem to be able to find how to get that particular env running.

I removed FourRoomQA because it wasn't used or maintained, but you can still find the code here if you want to use that as a starting point: https://github.com/maximecb/gym-minigrid/blob/4a8cace595876b9021b48a9bd8b635dd6fa65c80/gym_minigrid/envs/fourroomqa.py

Do note that some methods have been renamed since, eg: _randElem_ => _rand_elem

Hi Maxim,
Thank you so much for the code. I tweaked the file to my requirements (room objects and goal condition). I also used the fully observable wrapper as you mentioned.
But I can't seem to get rid of the mask that is rendered for depicting cells visible to the agent.

The fully observable wrapper produces a grid as an observation. The render method is for human viewing, that doesn't change with the fully observable right now.
