Dxu1994, thanks, that's what I wanted to hear, I just wasn't sure about the logic of multiple servers because that's my first online game I am working on, and I am serious about that, been working on it for a year and not willing to quit. But for now I am aiming this game for 50 people, it's not gonna be MMO right away. It will depend on the interest of the players and the cash that it will bring to get serious hosting gear.

I guess I am gonna start working on the mob server so in the future I wont have to do it.

You mean write a better server? Or buy a better host?

nono! I was saying that so that you could think of any way of making the mobs online. And I know what server is lol, I've wrote one. Currently it reads from the ini files and sends the info to the client saying what level is he and all the stats, except for the coordinates, client sends it's coordinates to the server and server sends those to all the players that are connected. Which is another hacking possibility that I am probably willing to fix by checking the last coordinates and the new once, and how different they are. But that will add some more delay to the server maybe... Same for the mobs, (yes I know that everything should be on the server side) if I will add mobs to the server, it will give more stuff to send to the client at the end it would be a whole book from each player to send lol, so I was thinking about creating ANOTHER server and host it on the different pc that will contain everything about the mobs, so basically client will connect to the Game Server and to the Mob server so that would be much less pressure for the server.
But I wonder if there is a different way to do it? Take a maplestory mmorpg for example, how does it work? I've seen some vacuum hackers which means that the mobs on this game are on the client and server only sends which way they should walk or something
What do you think?

Hello guys, I am decent java coder, and I probably can write anything. There is a game I've been working on for a year and managed to create own java game engine that currently contains advanced map editor. And the game it's self (client and the server) Right now people can join and see eachother and jump together and chat. Also server sends the stats of the player like level, health etc and applies it to the client. Everything works perfectly.
So, I am asking for some tips and techniques on making mob system, (I have the mob engine in the client, it has same physics as the character but with the different speed and it walks and jumps randomly and jumps if he sees that there is another platform next to it) so what should I do to make the mob online? Should I create another server specifically for mobs? Or should I add it to the main server? will it add unwanted lag? what should I do?

(this is how it looks like [made this video loong time ago])
