I think combat should be like NetHack, Brogue, DoomRL, or one of those games. Each turn you choose to attack, move, or do some other action, but if you run, the monster will probably follow you. It's a little advanced at the stage you're at, but that's just my thought.
Well, you can flee right now, if you want. Just try to walk away, theres a small chance, that you can escape. Ok, monsters that follow you and hunt you means more AI for the monsters, right now they are quite dumb, they check, if a player is close to them and then there is a chance, that they attack.
Making them more intelligent is a future plan, like you can tame them, they follow you as a pet and fight for you.
Or they really start to hunt players
The delay is between 1 second and 1.5 seconds. I'll try it again when I have time (since you changed it to the optimizer)
I changed a little bit more today, did some profiling with OProfile of the server and found 2 really nasty wastes of performance and fixed that.
So, for me, there is a performance increase right now like 50-75%. You can check that with the #ping command in game, that really shows the milliseconds a message takes to be sent from the applet to the game server and back.
And since the game server itself is busy with a lot of other things, like managing the world of the game, moving monsters and NPC's and such, the #ping might vary, depending on how fast the game server can reply.
I get right now a #ping between 7 and 500 milliseconds, which shouldnt be not that bad to play.
On the other hand, the server, where the game server runs on, is a virtual server, which might cause some performance problems itself.
Well, at least, its quite cheap
