    Hello,

    Disclaimer : I am new to ml-agents

    So I want to train 3 different agents that each control a different part of a machine in order to get a certain task done. From what I understood from this post :https://github.com/Unity-Technologi...sign-Agents.md#defining-multi-agent-scenarios, I need to give each agent a different Behavior Names and different team IDs, yet when making a SimpleMultiAgentGroup I need to give them the same behavior name and Behavior Parameters.
    So what should I do ?

    Depends how you want to train it. If each agent has a different behavior, then I believe it acts completely independently. This will be fairly unstable, but will learn. The SimpleMultiAgentGroup apparently does not support agents with differing behavior. One other option is to have a *single* mlagents Agent in your game, that controls all three machine parts. This might learn faster than three independent agents, since it means you basically have a single AI controlling the three machine parts in a co-ordinated way, a little like playing chess.
