Game session service
Chat service
Account service
(Rmi service, EtherealHost service)
1 - Can you please name some other services which we can have in games (mostly in mmorpg’s) ? (for better understanding)
2- Can we assume services as cross-cutting concerns (like aspects in Aspect Oriented Programming ) ? because services not directly relate to business logic (game logic) and should/can be used in any game.
It depends on the game. But for example, I could probably add quite a bit of stuff to make sim-eth-basic or sim-eth-es a full blown game without adding any new services. I cannot off the top of my head think about any new service that I would need. I might add one or two new methods to the existing game session but that’s it.
For Mythruna, I have some base services for handling dialog style interaction and a service for dealing with object actions. Mostly I did that because I’m trying to make them separate open source projects, though.
Once you’ve got your base game setup, I think creating new services will be pretty rare beyond the base services that something like sim-eth-* has.
