Modular engine systems
Rendering, input, combat, animation, state management, and persistence are separated into focused systems for easier maintenance.
Engineering project
Modular 2D RPG Engine
A custom 2D RPG engine built with C#, MonoGame, XML, and xUnit, focused on modular systems for rendering, input, animation, combat, persistence, and content editing.

Project overview
The context behindthe final result.
A closer look at the goals, decisions, and technical thinking that shaped the project.
The project began as a game and gradually evolved into a reusable engine with distinct systems for gameplay, rendering, input, persistence, and content creation.
Its primary value is the architecture behind the game: reusable components, data-driven content, testable systems, and tooling that reduces repetitive setup work.
Key features
What the projectneeded to accomplish.
Core capabilities delivered for Modular 2D RPG Engine.
Custom combat logic
Reusable combat components handle attacks, player actions, hit detection, and enemy interactions.
Animation system
Sprite animation supports movement, directional states, and reusable animated objects.
Save and load persistence
XML-based persistence stores and restores structured game data across play sessions.
WinForms editor tooling
A companion editor reduces manual configuration and speeds up content creation.
Automated testing
xUnit tests validate core systems and reduce regressions during ongoing development.
Engine flow
From input to rendered gameplay
Each frame captures player input, applies game-state changes, resolves interactions, updates animation, and renders the resulting scene.
- 0101
Input
Capture keyboard and player controls.
- 0202
Update
Apply game logic and state changes.
- 0303
Combat
Resolve attacks, collisions, and interactions.
- 0404
Animate
Update sprite frames and movement states.
- 0505
Render
Draw the updated scene through MonoGame.

Technical highlights
The systems behindthe interface.
Selected architectural and implementation decisions that shaped the project.
MonoGame rendering
MonoGame renders gameplay scenes, sprites, shapes, and interface elements.
C# engine architecture
The codebase is organized into separate systems with clear responsibilities.
XML persistence
Structured XML data supports save, load, and content-driven workflows.
Geometry and collision logic
Reusable shape and collision systems support attacks, objects, and interaction checks.
Desktop tooling
WinForms utilities support content creation outside the running game.
xUnit testing
Tests improve reliability during refactoring and feature development.
Challenges
The difficult partsshaped the better decisions.
The constraints and implementation problems that required the most thought.
Managing engine complexity
As the project grew, large systems had to be separated into smaller reusable components with clearer responsibilities.
Building reusable game systems
Systems needed to support different gameplay objects without becoming tightly coupled to one feature.
Improving content creation
Manual configuration became time-consuming, which led to the creation of dedicated editor tooling.
Future direction
Still evolving.Still worth refining.
