Overview

A real-time action RPG built solo as a student project in Unity3D. The game features melee and ranged combat, multiple weapon types, spells, a full inventory system, and RPG stat progression — all tied together with FSM-driven enemy AI that includes patrols, combat behaviours, multiple enemy types, and a boss fight.

The focus was on building each system from scratch with clean, extensible architecture — learning how the core pillars of an RPG (combat, AI, stats, inventory) connect and depend on each other.

Systems Built

[01] — Combat

Weapon & Combat System

Built a real-time combat system supporting both melee and ranged weapon types, alongside spells — each with distinct attack ranges, damage types, and cooldown behaviours. Weapons were data-driven, making it straightforward to add new types without modifying the core combat logic. Hit detection, damage application, and knockback were all handled through a unified combat resolution layer shared across player and enemy actors.

[02] — AI

Enemy AI (FSM)

Designed and implemented a Finite State Machine-driven AI system powering multiple enemy types — each with distinct patrol routes, detection radii, chase behaviours, and attack patterns. States transitioned based on player proximity, line-of-sight checks, and health thresholds. The boss fight used an extended FSM with phase transitions, escalating attack patterns, and special abilities triggered at health breakpoints.

Character Stats & Progression

Implemented the RPG stat layer — health, attack, defence, and speed — with a progression system that scales values on level-up. Stats fed directly into the combat resolution system, so weapon damage, spell power, and incoming damage calculations all derived from the character's live stat values.

[04] — Items

Inventory System

Built a slot-based inventory system for managing weapons, spells, and consumables — with item pickup, equipping, and dropping. Equipment slots wired directly into the stat system so equipping an item updated the character's combat stats in real time.

Context

Role

Solo developer. Designed, architected, and implemented every system in the project — from AI to inventory to combat resolution.

Purpose

Built as a student project to learn how the core pillars of an action RPG interconnect — combat, AI, progression, and inventory — by implementing each one from scratch.

Tech

Built in Unity3D with C#. No third-party gameplay frameworks — all systems written from the ground up.

Status

Completed student project. Full source available on GitHub.
