Great tutorial but few important things are missing

[meiry]

Hello this is realy great tutorial and example , but there are few things missing from your example the most important one is making the server Authoritative server model and Client side prediction . sending each move from the client is very much not efficient . please take a look at my tutorial on the subject . http://www.gamedevcraft.com/2016/08/part-1-multiplayer-websocket-game.html

Agree that it will fix the jumpy gameplay.
