Custom Multi Agent Environment Examples for RLlib

Hi everyone, i am new to MARL and RLlib. I want to learn how to build custom environments but i acutally did not find any current multi agent custom environment that actually works and serves as a good tutorial.
I tried this multiagentmaze environment from the book “Learning Ray” but it does not work:

and i tried the following tutorial:

but i did not work either. I guess the main problem is that these tutorials were build for the old gym and respective RLlib versions.
Where can i find good tutorials for newer versions of RLlib?


You could try abmarl. It provides support for quick, custom multi-agent environment building and integrates with rllib to use its algorithms for training. It’s got full tutorials covering many aspects of MARL and how to use abmarl effectively.
