Flappy Bird GRASP

A Flappy Bird clone game made with Unity applying GRASP.

📜 Kata Rules

• A controllable bird that flaps upward with input and is affected by gravity.
• Single input control for making the bird flap (e.g., mouse click, tap).
• A repeating background to create the illusion of movement.
• Moving vertical pipes with gaps that the bird must pass through.
• A score system that increases when the bird passes through pipe gaps.
• Bird collisions with pipes or the ground should result in a game over.
• A game over screen with the option to restart.

General Responsibility Assignment Software Principles

• 👨‍💻 Information Expert
  • Assign responsibility to the class that has the necessary information to fulfill it. This ensures that operations are performed by the objects that have the data needed.
• 🎨 Creator
  • Assign responsibility for creating an instance of a class to the class that has the necessary information to instantiate it, or that closely uses the created object.
• 🕹️ Controller
  • Assign responsibility for handling system events to a class that represents a use case or overall system behavior. The controller coordinates the activities triggered by the event.
• 💔 Low Coupling
  • Assign responsibilities to ensure that classes have minimal dependencies on each other. This reduces the impact of changes and increases reusability.
• 📚 High Cohesion
  • Assign responsibilities to ensure that classes and modules have a single, well-defined purpose. This increases clarity and maintains focus within a class or module.
• 🐤 Polymorphism
  • Assign responsibility for behavior, based on the type, to classes that inherit from a common superclass or implement a common interface. This allows different classes to be treated through a common interface.
• 🏭 Pure Fabrication
  • Assign responsibilities to a class that is not a part of the problem domain but is created to achieve low coupling, high cohesion, or other design goals. This class does not represent a concept from the real-world problem space.
• 🚏 Indirection
  • Assign responsibilities to intermediary objects to reduce the direct coupling between classes. This introduces an intermediary to control interactions, promoting flexibility.
• 🛡️ Protected Variations
  • Assign responsibilities to create a stable interface that protects the system from variations or changes in other parts. This shields parts of the system from changes, making it more maintainable.
