Panel Pop - Three.js Implementation

A faithful recreation of Panel de Pon / Tetris Attack / Puzzle League using Three.js and TypeScript.

🎮 About

Panel Pop is a modern web implementation of the classic puzzle game series, featuring:

• Authentic gameplay mechanics - Modeled after the original SNES version
• Modern web technologies - Built with Three.js, TypeScript, and Vite
• 60 FPS gameplay - Fixed timestep game loop for consistent performance
• Multiple game modes - Endless, VS, and Demo modes
• High code quality - Comprehensive testing and linting

🚀 Development Status

Phase 1: Foundation & Core Engine ✅ COMPLETED

• ✅ Project infrastructure and build system
• ✅ Three.js scene with orthographic camera
• ✅ Asset loading system with progress tracking
• ✅ Fixed timestep game loop (60 FPS)
• ✅ Basic sprite rendering system
• ✅ Development environment with hot reload
• ✅ Comprehensive test suite

Phase 2: Board System & Block Rendering ✅ COMPLETED

• ✅ 6x24 grid board system with proper indexing
• ✅ Block class with color and state properties
• ✅ Tile data structure with type, block, and garbage references
• ✅ Block mesh generation using Three.js materials
• ✅ Grid background rendering with visual guidelines
• ✅ Board renderer with visual state effects
• ✅ Integration with scene manager
• ✅ Success Criteria Verified - Visual display at localhost:3001 ✅

Next: Phase 3 - Input System & Cursor (Days 11-15)

🛠 Development

Prerequisites

• Node.js 18+
• npm or yarn

Quick Start

# Install dependencies
npm install

# Start development server
npm run dev

# Open http://localhost:3000

Development Commands

# Development
npm run dev              # Start dev server with hot reload
npm run build           # Build for production  
npm run preview         # Preview production build

# Code Quality (run before every commit)
npm run lint            # Check code style
npm run lint:fix        # Auto-fix style issues
npm run type-check      # TypeScript compilation check
npm run format          # Format code with Prettier

# Testing
npm run test            # Run all tests
npm run test:watch      # Run tests in watch mode
npm run test:coverage   # Generate coverage report
npm run test:ui         # Run tests with UI

Quality Assurance

Before committing code, ALWAYS run:

npm run lint && npm run type-check && npm run test && npm run build

🎯 Phase 2 Success Criteria

All Phase 2 objectives have been completed:

• ✅ Board displays initial random block configuration (6x24 grid with 5 colors)
• ✅ All 5 block colors render correctly (Purple, Yellow, Red, Cyan, Green)
• ✅ Grid aligns properly with blocks (32x32 tile system)
• ✅ Buffer row remains hidden (row 0 not visible)
• ✅ Visual state effects working (floating, matched, exploding states)
• ✅ Tests pass: 41/41 game logic tests ✅ 22/22 core system tests

🧪 Testing

The project maintains high testing standards:

• Unit Tests: Core game logic and systems
• Integration Tests: Component interactions
• Coverage Target: Minimum 80% line coverage
• Framework: Vitest + Testing Library

Run tests:

npm run test           # Run once
npm run test:watch     # Watch mode
npm run test:coverage  # With coverage
