Bonjour Alain,
well, yes no tutorials, simply do not have spare time for this. ArrayMaker is kind of meant to be used when you are already comfortable with playmaker AND arrays and hasthables and what they mean, so in that sense, it can be difficult to grasp for beginners and none coders.
Try to push and study the examples, and come back to me with any questions you have, for example ' in that fsm, I don't understand what's happening in state 'xxx' or 'could you explain hw you do this and that' and I'll happily reply here trying to make sense of all this.
bye,
Jean
