📚 Labs Overview

🔹 Lab 3 – Application Enhancements

The JavaAnimation application was extended with new UI elements, configuration options, and improved gameplay controls.

Key Features Added:

• Main Screen
• Configuration Screen
  • Added interactive controls:
    • Checkbox: Enable Shadow.
    • Radio buttons: Red, Green, Blue.
    • Slider (5–20) to adjust ball size dynamically (updates label).
• Game Integration
  • All settings affect the game directly (color, shadow effect, size).
  • Arrow key controls updated:
    • ⬅ Left: decrease speed (X direction).
    • ➡ Right: increase speed (X direction).
    • ⬆ Up: increase speed (Y direction).
    • ⬇ Down: decrease speed (Y direction).

🔹 Lab 4 – Refactoring & UI Improvements

Focused on enhancing the UI design and improving software structure using SOLID principles.

Key Improvements:

• UI Enhancements
  • Introduced styles.css for a more polished look.
• Exit Confirmation
  • Added a dialog to confirm before quitting, triggered by the Exit button or window close.
• Code Refactoring (SOLID Principles)
  • Extracted logic from Main.java into separate classes.
  • Introduced a Screen interface; each screen (MainScreen, GameScreen, ConfigureScreen) implements it.
  • Created a Frame interface to decouple Main from individual screen implementations.
  • Added a Game class under the model package to manage game data.
  • Added ScreenWithGame interface for screens that need access to game data.

🔹 Lab 5 – UI Redesign & GRASP Principles

Improved layout and refactored using GRASP design principles.

Key Features:

• Redesigned GameScreen layout with game area(board) at top, Back button at bottom.
• Game area enclosed in a visible rectangle with balanced margins.
• Applied GRASP principles:
  • Information Expert: Moved ball data and logic to Game.
  • Creator: Added GamePane to handle visualization.
  • Controller: Added GameController to handle input.

🔹 Lab 6 – Sprite System

Introduced a flexible sprite system with Factory and Singleton patterns.

Key Features:

• Created Sprite interface with getNode() and setXY().
• Implemented StarSprite (visual star).
• Added SpriteFactory (Singleton + Factory pattern) for sprite creation.
• Updated GamePane to display 10 randomly positioned stars at game start.
• Created UML diagram showing relationships between Sprite system components.
• Improved ball movement responsiveness.

🔹 Lab 7 – Entities & Frame-Rate Independent Movement

Shifted towards an entity-based architecture with time-based updates.

Key Features:

• Added GameConfig (Singleton) to manage configuration.
• Created GameEntity abstract class with Player and Food subclasses.
• Used process() method for frame-rate independent movement.
• Linked Sprites with Entities.
• Updated SpriteFactory as a middle layer between Game and GamePane.
• Added entity life cycles (eternal, limited, expired).
• Introduced PlayerSprite and Food linked to StarSprite.
• Food items with random lifespan (5–15s), some stationary, some moving.

---

🔹 Lab 8 – Gameplay Mechanics & Audio

Added generics to sprites, player life system, decorator pattern, and audio functions.

Key Features:

• Updated Sprite interface with generics.
• Player starts with 10s life; eating food adds +5s and shows flying “+1”.
• Applied Decorator pattern for low-life display.
• Game over when life reaches 0.
• Added audio with Facade pattern:
  • Background music.
  • Sound effects for eating, dying, and spawning.
