Unreal Networking Skill

Multiplayer networking for Unreal Engine.

Overview

This skill provides capabilities for implementing multiplayer games using Unreal's built-in networking system.

Capabilities

Replication

  • •Configure replicated properties
  • •Handle replication conditions
  • •Manage replication priorities
  • •Implement custom replication

Remote Procedure Calls

  • •Implement Server RPCs
  • •Create Client RPCs
  • •Handle Multicast RPCs
  • •Manage RPC reliability

Authority and Relevancy

  • •Handle server authority
  • •Configure network relevancy
  • •Manage actor ownership
  • •Implement client prediction

Dedicated Servers

  • •Build dedicated server targets
  • •Handle headless mode
  • •Manage server performance
  • •Implement session management

Prerequisites

  • •Unreal Engine 5.0+
  • •Network knowledge

Usage Patterns

Replicated Property

cpp
UPROPERTY(ReplicatedUsing=OnRep_Health)
float Health;

UFUNCTION()
void OnRep_Health()
{
    // Called on clients when Health changes
    UpdateHealthUI();
}

void GetLifetimeReplicatedProps(TArray<FLifetimeProperty>& OutLifetimeProps) const
{
    DOREPLIFETIME(AMyCharacter, Health);
}

RPC Implementation

cpp
UFUNCTION(Server, Reliable, WithValidation)
void Server_Fire(FVector Location, FRotator Rotation);

bool Server_Fire_Validate(FVector Location, FRotator Rotation)
{
    return true; // Add validation
}

void Server_Fire_Implementation(FVector Location, FRotator Rotation)
{
    // Execute on server
}

Best Practices

  1. •Validate all server RPCs
  2. •Minimize replicated properties
  3. •Use relevancy wisely
  4. •Test with simulated lag
  5. •Profile network bandwidth
