Horror Game :: Patterns practice

A simple 3D horror game. You have to collect all the keys on the map before the Evil Pumpkin catches you

This education project demonstrates the implementation of Model-View-Presenter (MVP) architectural pattern along with Composite Root in Unity

Controls

• WASD (Movement)
• Mouse (Camera)

Code structure

Key Patterns Used

Model-View-Presenter (MVP)

In this project:

• Model: Contains game data and business logic (domain layer)
• View: Handles visual representation and user input (presentation layer)
• Presenter: Mediates between Model and View (application logic layer)

Composite Root

The Composite Root pattern is used to:

• Centralize object composition
• Manage dependencies between components
• Initialize the entire object graph in one place

How It Works

1. Initialization:

   • The CompositeRoot script creates and wires all components together
   • It resolves dependencies between systems, models, and presenters

2. Data Flow:

   • User input is captured by the Input system
   • Input events are processed by presenters
   • Presenters update the Model and notify the View
   • View reflects the current state from the Model
