SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides the foundational knowledge and code examples to implement real-time multiplayer functionality in Unity games using Netcode for GameObjects (NGO).

Core Features & Use Cases

  • Host/Client Architecture: Set up and manage network connections.
  • State Synchronization: Synchronize game state using NetworkVariables.
  • Remote Procedure Calls (RPCs): Implement client-to-server and server-to-client communication.
  • Networked Object Spawning: Dynamically spawn and despawn networked objects.
  • Unity Gaming Services Integration: Utilize Lobby and Relay for matchmaking and connection.
  • Use Case: Develop a co-op puzzle game where players can interact with shared objects, or a competitive shooter where player actions are synchronized across all clients.

Quick Start

Install the Netcode for GameObjects package and set up a NetworkManager component on an empty GameObject.
