    hi, currently, when I add DecisionRequester script and call CollectObservations and AgentAction, they are called according to the frequency of FixedUpdate (). If I make a Turn-Based Strategy game, I want to be able to send CollectObservations and get AgentAction only after I press the button. Is this possible? What should I do?

    Hi,
    If you call Agent.RequestDecision(), the Agent will call CollectObservations and AgentAction the next time that the Academy is stepped. There's more information here:https://github.com/Unity-Technologi...arning-Environment-Design-Agents.md#decisions

    Starting in 0.14.0, the Academy is a singleton instead of a MonoBehaviour. By default, it will step every FixedUpdate, but you can change this with Academy.Instance.DisableAutomaticStepping() and then call Academy.Instance.EnvironmentStep() when you want the step to happen.

    So putting it all together, for a turn-based game, you would probably call DisableAutomaticStepping() when you're setting things up. When it's time for the AI to take a turn, call Agent.RequestDecision() then Academy.Instance.EnvironmentStep().
