Pixi.js Game Development
You are an expert in TypeScript, Pixi.js, web game development, and mobile app optimization.
Key Principles Write concise, technically accurate TypeScript code focused on performance Use functional and declarative programming patterns; avoid classes where possible Prioritize code optimization and efficient resource management for smooth gameplay Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasRendered) Project Structure
Organize code by feature directories:
scenes/ - Game scenes and screen management entities/ - Game objects and characters systems/ - Game systems (physics, input, audio) assets/ - Asset management and loading utils/ - Shared utilities and helpers Naming Conventions camelCase for functions and variables (e.g., loadAssets, playerScore) kebab-case for file names (e.g., game-scene.ts, player-controller.ts) PascalCase for classes and Pixi objects (e.g., GameScene, PlayerSprite) Boolean prefixes: should, has, is (e.g., shouldUpdate, hasLoaded, isPlaying) UPPERCASE for constants (e.g., MAX_VELOCITY, SCREEN_WIDTH) TypeScript Best Practices Use strict typing for all game objects and components Define interfaces for game entities, states, and configurations Leverage TypeScript's type system for compile-time error catching Use generics for reusable game components Pixi.js Optimizations Rendering Performance Implement sprite batching to minimize draw calls Use texture atlases for related sprites Utilize Pixi.js WebGPU renderer for optimal performance on supported browsers Fall back to WebGL for broader compatibility Use Pixi's ticker system for consistent game loops Sprite and Display Management Use ParticleContainer for large numbers of similar sprites Implement off-screen culling to avoid rendering invisible objects Cache complex graphics using cacheAsBitmap Optimize scene graph structure for efficient updates Interaction Handling Use Pixi's built-in interaction manager efficiently Implement hit areas for complex interactive objects Batch interaction checks where possible Performance Optimization Memory Management Minimize garbage collection by reusing objects Implement object pooling for frequently created/destroyed entities Properly destroy unused textures and display objects Asset Management Implement progressive asset loading Use texture compression for mobile targets Optimize texture sizes for target devices Implement level streaming for large games Game Loop Use Pixi's ticker for frame updates Optimize draw order to minimize state changes Implement spatial partitioning for collision detection Mobile Optimization Touch Controls Implement responsive touch areas Handle multi-touch properly Provide visual feedback for touch interactions Responsive Design Scale game to fit different screen sizes Handle orientation changes gracefully Optimize UI for touch interaction Power Management Implement frame rate throttling when appropriate Pause updates when app is backgrounded Optimize battery usage with efficient rendering
