# Analysis Process
Before responding to any request, follow these steps:

1. Request Analysis
 - Determine task type (code creation, debugging, architecture, etc.)
 - Identify languages and frameworks involved
 - Note explicit and implicit requirements
 - Define core problem and desired outcome
 - Consider project context and constraints

2. Solution Planning

 - Break down the solution into logical steps
 - Consider modularity and reusability
 - Identify necessary files and dependencies
 - Evaluate alternative approaches
 - Plan for testing and validation

3. Implementation Strategy

 - Choose appropriate design patterns
 - Consider performance implications
 - Plan for error handling and edge cases
 - Verify best practices alignment

# Code Style and Structure
## General Principles
 - Write concise, readable TypeScript code
 - Use functional and declarative programming patterns
 - Follow DRY (Don't Repeat Yourself) principle
 - Implement early returns for better readability
 - Structure components logically: exports, subcomponents, helpers, types
 - Build extensible and maintainable code 

## Naming Conventions
 - Use descriptive names with auxiliary verbs (isLoading, hasError)
 - Prefix event handlers with "handle" (handleClick, handleSubmit)
 - Use lowercase with dashes for directories (components/auth-wizard)
 - Favor named exports for components

## TypeScript Usage
 - Use TypeScript for all code
 - Prefer interfaces over types
 - Avoid enums; use const maps instead
 - Implement proper type safety and inference
 - Use satisfies operator for type validation


## Pixi.js Specific Optimizations
 - Implement proper game loop using Pixi's ticker system for consistent updates and rendering.
 - Utilize Pixi.js WebGPU renderer for optimal performance on supported browsers, falling back to WebGL for broader compatibility, especially for Ionic Capacitor builds.
 - Use sprite batching and container nesting wisely to reduce draw calls.
 - Implement texture atlases to optimize rendering and reduce texture swaps.
 - Utilize Pixi.js's built-in caching mechanisms for complex graphics.
- Properly manage the Pixi.js scene graph, removing unused objects and using object pooling for frequently created/destroyed objects.
- Use Pixi.js's built-in interaction manager for efficient event handling.
- Leverage Pixi.js filters effectively, being mindful of their performance impact.
- Use ParticleContainer for large numbers of similar sprites.
- Implement culling for off-screen objects to reduce rendering load.

## Advanced Techniques
- Understand and use Pixi.js hacks when necessary, such as custom blending modes or shader modifications.
- Be aware of gotchas like the 65k vertices limitation in graphics and implement workarounds when needed.
- Utilize advanced features like custom filters and multi-pass rendering for complex effects.

## Code Structure and Organization
- Use design patterns appropriate for simulator development (e.g., Observer, Command, State patterns).

## When suggesting code or solutions:
1. First, analyze the existing code structure and performance implications.
2. Provide a step-by-step plan for implementing changes or new features.
3. Offer code snippets that demonstrate best practices for Pixi.js and TypeScript in a game development context.
4. Provide explanations for why certain approaches are more performant or efficient.
5. Be aware of potential Pixi.js gotchas and hacks, and suggest appropriate solutions when necessary.

Follow the official Pixi.js documentation for up-to-date best practices on rendering, asset management, and performance optimization.
