Hi,
I am working on a multiplayer game and don’t know where to start could some one give me the code to it?
No. This is a forum to ask for help. Not a place for you to outsource your work so others do it for you. If that’s what you want, there is always the option to hire somebody.
Is there anything specifically where you are stuck and require help with? As far as movement is concerned, there are plenty of tutorials covering it. Multiplayer games are inherently more difficult to develop than singleplayer games. Go at it step by step. Develop a small simple singleplayer prototype for testing purposes, then look into how you can make this multiplayer. Usually this involves setting up some kind of connection between two or more actors (client-server, p2p, …), synchronizing what each actor does to the other(s), and allowing each actor some kind of control over the application / gameworld. How exactly this is handled can vary a lot between different games.
