ℹ️ Networking history: This project originally used Photon Bolt. That backend has been deprecated and preserved on the photon-bolt branch. The master branch now runs on Unity Netcode for GameObjects behind a framework-agnostic networking layer (see Architecture).

🏗️ Architecture

The codebase is split into assemblies (.asmdef) with a strict dependency direction, so gameplay logic never depends on any networking framework:

Game.Core  ──────────────►  Game.Common
   │  (pure gameplay: units, spells,
   │   auras, combat — no net deps)
   ▼
Game.Net.Abstraction  ◄── framework-neutral interfaces & messages
   ├── Game.Net.Local  (single-player / offline backend)
   └── Game.Net.Ngo    (Netcode for GameObjects backend)

Game.Server   ── authoritative server logic
Game.Client   ── presentation, split into:
   ├── Game.Client.UI          (unit frames, action bars, lobby, chat)
   ├── Game.Client.Effects     (spell/projectile/aura VFX)
   ├── Game.Client.Sound       (spell, UI and character audio)
   └── Game.Client.Localization
Game.Launcher ── bootstrap, DI installers, scene flow
Game.Editor   ── editor tooling

The networking framework lives only in adapter assemblies (Game.Net.Ngo, Game.Net.Local). Game.Core references just Game.Common, and the asmdef dependency graph enforces that wall at compile time — making the netcode backend swappable.

⚔️ Combat System

Combat is fully data-driven. Content consists of reusable ScriptableObject Balance Definitions:

• Spells are assembled from one or more Spell Effects (the things a cast does).
• Auras are assembled from one or more Aura Effects (the persistent buffs/debuffs a spell applies).

This makes new abilities largely a matter of authoring assets — see the wiki guide: How to add a new spell.

Spell kit

A World of Warcraft Mage kit (plus a few support spells), grouped by school:

🔥 Fire	❄️ Frost	🔮 Arcane / Utility	✨ Support

Flame Strike	Frost Nova	Counterspell	Holy Word: Serenity
Living Bomb	Cone of Cold	Arcane Intellect	Pain Suppression
Fire Blast	Deep Freeze	Presence of Mind	Resurrect
Blazing Speed	Ice Barrier · Ice Block	PvP Trinket
Hot Streak (proc)	Icy Veins · Ice Nova
	Fingers of Frost · Shatter

Spell Effects — what a cast can do

Damage · Heal · Apply Aura · Area Effects · Direct Teleport · Dispel Mechanics · Kill · Resurrect

Aura Effects — buffs & debuffs auras can apply

Periodic Damage · Periodic Healing · Absorb Damage · Damage Reduction · Critical Damage · Haste · Speed · Stat Mod · Spell Modifier · Spell Trigger · Stun · Freeze · Root · Silence · Pacify · Confuse · Immunity · Slow Suppression · Ignore Aura State · Display Model

✨ Implemented Features

• Networking — server instances and client connections via Netcode for GameObjects, with single-player, LAN, and online (Relay) backends behind a shared abstraction.
• Player — World of Warcraft–style player controller and third-person camera.
• World — arena location setup (Lordaeron map) and the Sirus boss-fight scenario.
• Combat — data-driven spells, spell effects, auras and aura effects (see above).
• UI — unit frames, action bars, customizable hotkeys, lobby, chat, floating combat text, unit selection projectors.
• Presentation — visual effects for casts, projectiles and auras; spell, UI and character sounds.
• Systems — localization with spell-error notifications; AI behavior graphs for scripted encounters.

🚀 Getting Started

Setup

Open the project in the Unity Editor version specified in ProjectSettings/ProjectVersion.txt. Enter play mode from the Launcher scene (Assets/Scenes/Launcher).

Build

The Launcher scene must be included first, followed by the playable locations.

Play

From the lobby:

• Single Player — start a local session and play offline.
• Start Server — host a session, advertised for LAN/online clients to discover.
• Start Client → wait for sessions to appear → Connect. If a connection fails, the reason is shown at the bottom of the lobby panel.
