Question

I’m building a little MMORPG and im trying to use asyncore rather then threading.

1) How would i send data to certain clients, because in threading a saved each clients socket and current in a dictionary a with its unique id as a key. So how could i subjective send data to all the clients.

Thankyou, please say if i didnt give enough information

Answer 1

I find it great that you want to move to asynchronous programming instead of threading, since it is so much reliable and easier to debug.

However, asyncore is a bad library to do so. I don’t advise you use it at all, since it requires a significant rewrite to do simple things like read standard io.

I suggest you move to twisted – it is a great asynchronous framework, well tested and developed, with good api documentation and good community support.

Regardless of your decision on which library to use, I find this series of blog posts by Dave Peticolas to be a great source of beginner information on asynchronous programming. Please read it.

There are some games under development using twisted. One example is Minions of Mirth – I never played it but it seems cool.

There’s also divmod’s imaginary – it’s a simulationist’s take on the realm of role playing, interactive fiction, and multiplayer dungeons. It incorporates gameplay features from each area while attempting to provide a richer environment than is generally available from existing systems.

Hope I helped.
