Unreal Engine Unreal Engine Networking & Multiplayer

Question 1

What is the default networking architecture used in Unreal Engine multiplayer games?

Accepted Answer

Client-Server

Answer

Unreal Engine uses a Client-Server model where the server is authoritative and clients send input while receiving replicated state.

Question 2

Which AActor property must be set to true in Unreal Engine to enable replication for that actor?

Accepted Answer

bReplicates

Answer

Setting bReplicates = true on an AActor tells Unreal Engine to synchronize that actor's replicated properties and RPCs across the network.

Question 3

What does RPC stand for in Unreal Engine networking?

Accepted Answer

Remote Procedure Call

Answer

RPC stands for Remote Procedure Call, which allows functions to be executed on a remote machine (server or client) over the network.

Question 4

Which RPC type in Unreal Engine is guaranteed to execute on the server, regardless of which machine calls it?

Accepted Answer

Server RPC

Answer

A Server RPC (marked with the Server specifier) always runs on the server, making it ideal for sending player input or requests to the authoritative machine.

Question 5

In Unreal Engine multiplayer, where does the GameMode exist?

Accepted Answer

Only on the server

Answer

GameMode only exists on the server because it governs authoritative game rules; clients access game state through GameState instead.
