[gameprogrammer] Re: online server, propagating changes

Do you have to notify them? Couldn't you just change the world state and
have anyone interested ask?
What I think you are trying to do is: give a step and declare "I just made a
step", when it's much easier to just make the step and make anyone see you
and realise what just happened.
Since all objects near the player will have to react to something, it
doesn't matter if the player does or does not do something in order for them
to act (though, then again, I have no idea of how your rpg works), so really
I think you'd be more interested in instead knowing, or being notified (on
demand) of what the entities near one do.
So when the player moves, only those entities that ask would know that he
moved, those that where close to the player but couldn't care less (like
maybe a rock, or something like that) wouldn't have to be notified at all. A
creature that might be more reactive (a creep or something) would just ask
to be notified what all the things around it are doing, so if anyone is
attacking it, it would know and react acordingly.
I think I'm starting to go in circles and using to many words for what I'm
trying to say, so I hope that this helps, though I might have misunderstood
what you want.

Yes, I dont know the exact term to define it. What I need to do is the
following:

if X starts walking:
    notify all entities in visible range

Not just "walking", but any state change or action, like X starts
attacking Y,  or changes armor, equips a new weapon, etc.
