CityBuilder

Scalable Game Architecture with Persistent State Management

A production-ready city building game demonstrating enterprise-grade architecture patterns for persistent game state, resource management, and extensible building systems. Built with patterns proven across 10+ years developing strategy titles at Ubisoft and other studios.

🎥 Demo

🎮 Core Features

Resource Management – Automated TownHall production with manual collection for secondary buildings
Dynamic Building System – Expandable building types via static data configuration
State Persistence – Robust game state serialization and recovery
Interactive Modes – Build and move modes with intuitive placement system

🏗️ Technical Architecture

Production-Grade Patterns:

• MVP (Model-View-Presenter) – Enforced separation of concerns for maintainable codebase
• Dependency Injection (Zenject) – Loosely coupled components for scalability
• Reactive Programming (UniRx) – Efficient event-driven state updates
• State Machine – Clean mode transitions (Build/Move/Regular states)
• Generic Object Pooling – Optimized memory allocation for mobile performance
• Promises (C#) – Non-blocking asynchronous operations

Data Architecture:

• Metadata-driven building system via ScriptableObjects
• Persistent game state with JSON serialization
• Separation of static data and runtime state for clean save/load
