Feature request: update PettingZoo version #209
Description
Hi, would it be possible to update this repo to use the most recent version of PettingZoo? We want to list this project in PettingZoo's third-party-environments, but we can only include environments which work with the current version.
If you need any help working out issues due to different versions feel free to ask, there were some breaking changes in version 1.2, so it requires a bit of code changes to adapt. The previous API returned done in the step() function, whereas the new one returns truncated and terminated (matching gymnasium). There is a migration guide for gymnasium explaining the changes further, the steps should be basically the same (we're working on making resources for updating old PettingZoo repositories as well): https://gymnasium.farama.org/content/migration-guide/
This issue #204 mentioned the breaking changes previously (involving dones), but hopefully I can provide a little more information and help with updating.
