Entity Systems are the Future of MMOs Part 5

(Start by reading Entity Systems are the Future of MMOs Part 1)

It’s been a long time since my last post on this topic. Last year, I stopped working for a big MMO publisher, and since then I’ve been having fun doing MMO Consultancy (helping other teams write their games), and iPhone development (learning how to design and write great iPhone apps).

Previously, I posed some questions and said I’d answer them later:

  • how do you define the archetypes for your entities?
  • how do you instantiate multiple new entities from a single archetype?
  • how do you STORE in-memory entities so that they can be re-instantiated later on?

Let’s answer those first.
