Thanks for this.

So first it should be compatible with torchrl.
If you have it in PettingZoo or VMAS or other already compatible interfaces this is already the case.

Then you need to create a new task https://github.com/facebookresearch/BenchMARL/tree/main/examples/extending/task

Here is a PR example of following this process and adding a new task #84

My environment is a mpe environment, like https://github.com/openai/multiagent-particle-envs, so i don't know how to use it on benchmarl, i'll try this https://github.com/facebookresearch/BenchMARL/tree/main/examples/extending/task, thanks

That's great, we are compatible in many ways with MPE envs!

You could use the PettingZoo interface (there are already other MPE envs in benchmal through that). Basically following something like #84

Or you can implement it vectorized using VMAS (https://github.com/proroklab/VectorizedMultiAgentSimulator) which basically is compatible with all MPE features but faster
