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). My game functionality would resemble League Of Legends or Dota 2 functionality.
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.
