This repository is a complete multiplayer co-op game sample called 'Boss Room', built by Unity Technologies to demonstrate best practices for using Unity Netcode for GameObjects (NGO). It implements a server-authoritative action RPG where up to 8 players cooperate to defeat a boss in a dungeon. The architecture is modular and state-driven: a connection state machine (Offline, ClientConnecting, Hosting, etc.) manages network lifecycle, while game flow states (MainMenu, CharSelect, BossRoom, PostGame) control scene transitions and gameplay logic. The core gameplay revolves around a ScriptableObject-based action system where abilities (melee, projectiles, buffs, stealth, etc.) are defined as data assets and executed via server-side action players with client-side anticipation for latency masking. The project integrates Unity Gaming Services for authentication, session management, and relay, and uses VContainer for dependency injection. Key entry points include ApplicationController (DI setup), ConnectionManager (network state machine), and GameStateBehaviour subclasses. Data flows involve client input sent via RPCs, server-side processing with NetworkVariables for state sync, and a typed NetworkedMessageChannel for decoupled event broadcasting. External dependencies include Unity Netcode, Unity Transport, Unity Gaming Services, VContainer, Cinemachine, and URP.
This repository contains the source code and assets for ActionRoguelike, a roguelike action game built with Unreal Engine 5. The game features procedural enemy spawning, a variety of player actions (such as dashing, magic projectiles, and parrying), and performance-optimized systems for managing actors and significance. The codebase is organized into modular subsystems, including AI, action systems, core game mechanics, player controls, and UI. The architecture follows Unreal Engine best practices, with clear separation of concerns. Notable reusable systems include a custom action system that allows developers to define and manage player abilities, and an actor pooling subsystem that optimizes performance by reusing instances of frequently spawned objects. The project also implements a save system for persisting game state and a significance system to prioritize updates for important actors. While the project is tailored to a specific roguelike game, several of its systems are designed with reusability in mind. The ActionSystem and Performance modules, in particular, could be extracted and adapted for use in other Unreal Engine projects with minimal modification. The recent commit activity indicates active maintenance, and the use of a recent Unreal Engine version suggests low technical drift. Overall, the codebase demonstrates solid engineering practices and provides a foundation for learning and building similar action-oriented games in Unreal Engine.
