Consult the network, multi-player, online game synchronization problem。

  1. I downloaded UE4, the official third-person Demo. Pack as Windows 64 bits and place on 3-4 pc devices with Lan online. Two computers online when fine, three or four computers online when there will be a pause, the situation of teleportation.

2.I myself made a multiplayer online game, with source code compilation Development Sever out of a stand-alone Server, set up to the cloud server. Slight rollback problem while online via Ip. As if: The character went to the front and was dragged back half a step.

Issue:
I’m curious as to what exactly these emerging network synchronization problems are。
