🕹️ DX-Ball: Physics-Based Brick Breaker

Custom Game Engine with Real-Time Physics & Animation

This project is a high-fidelity recreation of the classic DX-Ball game. It is built from scratch using Java to demonstrate core game development principles, including deterministic physics, collision detection, and modular game loops.

🚀 Key Features

• Custom Physics Engine: Implements both surface and corner collisions using dot product calculations and vector reflections.
• Real-Time Animation Loop: Utilizes double-buffering via the StdDraw library to ensure smooth, flicker-free rendering.
• Dynamic Gameplay Modes: Includes a 'Monster Mode' featuring increased difficulty, paddle speed adjustments, and inverted controls.
• Interactive UI: Real-time score tracking, shooting angle adjustment, and pause/resume functionality.
• Visual Feedback: Dynamic background color shifts triggered by paddle collisions and localized victory/game-over states.

🏗️ Technical Implementation

• Collision Detection: Categorized into surface (velocity negation) and corner collisions (normal vector reflection).
• Modular Logic: Features a centralized loop for input handling, physics updates, and scene rendering.
• Mathematics: Employs vector math to calculate reflection angles and maintain constant ball velocity magnitude.

🛠️ Installation & Execution

1. Ensure you have the JDK 8+ installed.
2. Include the stdlib.jar in your classpath.
3. Run the ModifiedMain file to choose between Normal or Monster mode. (Main file runs only Normal mode)
