This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

Anterix Launch: Spectrum Defender is a retro arcade game combining Asteroids (rotation/thrust mechanics) with Space Invaders (wave-based enemies). The entire game is contained in a single HTML file (

index.html

) with embedded CSS and JavaScript - no build step or external dependencies required.

Running the Game

# Open directly in browser - no build required
start index.html          # Windows
open index.html           # macOS
xdg-open index.html       # Linux

Optional Sprite Generation

For DALL-E generated pixel art sprites (optional enhancement):

cd scripts
pip install -r requirements.txt
set OPENAI_API_KEY=your-key-here  # Windows
export OPENAI_API_KEY=your-key-here  # Linux/macOS
python generate_sprites.py

Architecture

Single-File Design

The game is intentionally architected as a single

index.html

file (~100KB) containing:

CSS (lines 7-95): Retro CRT aesthetic with scanline effects and neon glow
JavaScript (lines 106+): Complete game engine

JavaScript Code Sections

The code is organized into clearly labeled sections:

Configuration & Constants (
```
CONFIG
```
object): All tunable game parameters
Utility Functions (
```
Utils
```
class): Math helpers, collision detection, screen wrapping
Audio System (
```
AudioManager
```
class): Web Audio API procedural 8-bit sounds
Game Objects: Player ship, enemies, projectiles, power-ups, particles
Game Loop: State management, update/render cycles, wave progression

Key Classes

```
Utils
```
: Static helpers for distance, collision, screen wrapping
```
AudioManager
```
: Procedural sound generation (no audio files)
```
Player
```
: Ship with Asteroids-style rotation/thrust physics

Enemy types:

SignalDisruptor

DataPacket

NetworkNode

LegacyTower

SpectrumJammer

Power-ups:

BandwidthBoost

SignalShield

SpectrumSpread

NetworkSurge

Configuration

All game balance parameters are centralized in the

CONFIG

object at the top of the script:

Player physics (rotation speed, thrust, friction, fire rate)
Point values per enemy type
Power-up durations
Color palette (neon cyan/magenta/yellow theme)
Combo system timings

Technical Constraints

No external dependencies for core game - must work offline
Single HTML file - all CSS/JS embedded
Target 60 FPS on modern browsers
< 100KB total (excluding optional sprites)
Browser support: Chrome 90+, Firefox 88+, Safari 14+, Edge 90+
