SOME OF MY PROJECTS
2.5D FPS Engine
An experimental 2.5D FPS prototype built in Unity3D, with a focus on clean code, abstraction, and polymorphism. Features a raycast-based movement system and a modular, pluggable AI built on the state machine pattern, using ScriptableObjects and interfaces for flexibility.
The AI navigates with Unity’s NavMesh and supports patrolling, random coordinate searching, and chasing targets upon detection. I also integrated my own dependency injection framework, improving modularity and reducing tight coupling across the architecture. Project here!
Raycast 2D Platform Engine
A 2D platforming engine built in Unity3D, using raycasting for collision detection and movement instead of the default physics system. Based on an Official Unity tutorial, I played around with it to shaders, pixelated camera and a scriptable object-based AI state machine, akin to the one used in my 2.5D FPS engine.
Project here!
Cross Scene Unmask GUI Framework
An experimental sub module extension of the Scene Unmask tool adding cross-scene functionality via a custom tagging system, while fully preserving its core features. This enhancement also allows customizing how the unmask fits—by size, position, or both—expanding usability for cross-scene elements without compromising the original tool. Originally developed to meet a specific requirement in one of my games.
