The server needs to handle the physics, because all the movement will be handled by it. So for that I need a game loop. The thing is that the server doesn't have the render part, it's just a console.

All the posts I found on the internet were involving the render part. I'm not stupid, I know I should not take in consideration that part but then which type of loop should I use? (fixedtimestep, semi-fixed).

Actual questions:

1.What is the server functionality for this type of game?

2.What does the game loop look like?

Additional info: I use libGDX for the client part, and JBox2D on the server part, KryoNet for Networking and thinking of using lwjgl (only the System class) for Native timers.

I searched the webs lately searching for a good way to implement the game-loop on my server.

Background info:

I am trying to make a 2d sidescroller multiplayer game. The client cycle would looks something like this:

Client functionality! http://i.imgur.com/Ma0XAUa.jpg

The client cycle should be clear. The actual game (playable part) will be in the game screen and will involve 2 players (maybe 4 later). Now, on the server path i need to handle the physics, because all the movement will be handle by it. So for that i need a game loop. The thing is that the server doesn't has the render part, it's just a console. All the posts i found on the internet were involving the render part.

Also should i create a world in which to add the players at each found-opponent event?

Actual questions:

1.What is the server functionality for this type of game?

2.How does the game loop look like?

3.How should I handle the physics? One world, multiple clients or multiple worlds for every 2 clients (game)?

P.S. : My game functionality would resemble League Of Legends or Dota 2 functionality (If you know how does game client cycle look like).
