What is the best way to arrange lots of actors?

I mean it like with mobs, enemies. Different type of enemies but the ‘take damage’ event is the same on all of them. Should I make chile actors from ‘mob’ actor or is there any other method?

Yes, inheritance is definitely the way. In addition, you can splash in some component magic for reusable behaviour, look into Event Dispatchers and stir it up with Interfaces.

Thank you!
