Project Overview

A digital recreation of the classic playground game Hopscotch, featuring interactive graphics, physics-based stone throwing, accurate jump mechanics, and a comprehensive scoring system. The game captures the nostalgic feel of the playground classic while adding modern gaming features like achievements and multiplayer support.

Key Features

  • Authentic hopscotch gameplay with traditional rules
  • Physics-based stone throwing mechanics
  • Smooth character animation and movement
  • Multiple game modes (Classic, Timed, Challenge)
  • High score tracking and achievements system
  • Customizable court designs and themes

Technical Implementation

Architecture

The game uses a component-based architecture with separate systems for different mechanics:

  • Game Engine: Turn-based logic handling player actions and rule enforcement
  • Physics System: Projectile motion for stone throwing
  • Animation Controller: Sprite-based character movement
  • Input Handler: Keyboard and mouse controls
  • Score Manager: Points calculation and achievement tracking
Technologies Used
  • Java: Core programming language
  • Swing/Graphics2D: UI and rendering system
  • Custom Physics: Parabolic trajectory calculations
  • Sprite Animation: Frame-based character movement
  • Event System: Input handling and game state transitions

Challenges & Solutions

Challenge: Realistic Stone Physics

Solution: Implemented parabolic trajectory equations with drag coefficient to make stone throwing feel natural and predictable while maintaining game balance.

Challenge: Smooth Character Animation

Solution: Created a sprite animation system with interpolation between frames to ensure fluid hopping motion across squares.

Challenge: Rule Validation

Solution: Built a state machine to track valid moves and automatically detect rule violations like line stepping or improper hopping patterns.

What I Learned

  • 2D game physics and trajectory calculations
  • Sprite animation techniques and frame management
  • Game state management and rule enforcement
  • User input handling and control schemes
  • Balancing nostalgia with modern game design
