Welcome to a modular and high-performance top-down shooter built with Unity’s ECS (Entity Component System) and DOTS (Data-Oriented Technology Stack). This project is a perfect example of scalable gameplay where systems, components, and entities work together to deliver dynamic game mechanics.
Entity-Component Architecture
Modular systems that separate logic and data for better performance and flexibility.
Player Mechanics
- WASD or joystick-based movement
- Direction-based animation
- Ranged plasma blast attack
- Health and gem UI integration
Enemy AI
- Automatically tracks and moves toward the player
- Attack with cooldown system
- Drops gems when defeated
Gem Collection
- Pick up system with collision detection
- Real-time UI update
Camera System
- Smooth player-following using singleton-based camera reference
Game UI
- Pause/resume system
- Game over screen
- Dynamic gem and health UI
