How to Replicate Actors

Guide for Replicating Actors in Multiplayer Games.

On this page

The process of passing data or commands between Server and Clients is referred to as Replication, and Actor Replication is where the Server identifies and acknowledges if an Actor is set to use Replication or not. If the Actor is set to Replicate, the Server will tell the Client to create and maintain a Replicated copy of that Actor on the Client's machine. The Server always has the authoritative version of that Actor, while a Client (or multiple Clients) may have the approximate, replicated versions of that Actor.

Options can be set to define how Replicated Actors behave on a Client, from whether or not to Replicate Movement (the location/rotation of the Actor) to setting its Network Relevancy (or when to send Replicated Data to the Client, as the Actor set to Replicate may or may not be relevant depending upon gameplay situations).

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
