Step 6: Add visual effects, settings management, and notification system

[Copilot]

Implements design polish and extension foundations for the Kitchen Chaos game as specified in Step 6 requirements.

Visual Effects System

• ANSI color support (16 colors + 8 bright variants + backgrounds)
• Multi-color gradient text rendering
• Progress bars with customizable styling
• Box decorations, banners, status icons (✓, ✗, ⚠, ℹ)
• Animation support (spinners, typing effects)

from visual_effects import VisualEffects, Color

VisualEffects.print_success("配達成功！")
VisualEffects.print_progress_bar(0.75, label="料理中", color=Color.GREEN)
print(VisualEffects.gradient_text("Kitchen Chaos", [Color.RED, Color.YELLOW, Color.GREEN]))

Settings & Notification Infrastructure

• Settings Manager: JSON-persisted configuration with Singleton pattern

  • Game parameters (spawn timing, max recipes, duration)
  • Visual toggles (colors, animations)
  • Debug flags

• Notification System: Event-driven with 4 severity levels (INFO, SUCCESS, WARNING, ERROR)

  • Category-based filtering
  • Observer pattern with subscriptions
  • Timestamped history management

from settings_manager import SettingsManager
from notification_system import notify_success, NotificationSystem

settings = SettingsManager.get_instance()
settings.set_setting("spawn_recipe_timer_max", 3.0)

system = NotificationSystem.get_instance()
system.subscribe(lambda n: print(f"{n.level}: {n.message}"))
notify_success("レシピ配達完了", "delivery")

Documentation

• Comprehensive README with usage examples and configuration reference
• Complete API documentation covering all 7 modules
• Interactive examples file with 6 demo scenarios
• Implementation summary documenting architectural decisions
• Bilingual (Japanese/English) inline documentation

Enhanced Main Demo

Integrated visual effects and notification system into main.py:

• Gradient title display
• Real-time game status boxes
• Progress bars for delivery simulation
• Emoji-enhanced recipe names (🍅🥬🍞🧀)
• Notification statistics summary

Security

Removed SQL injection vulnerability in DeliveryManager.get_recipe_by_name() method that constructed queries via string interpolation.

Files Added

• visual_effects.py (232 lines)
• settings_manager.py (123 lines)
• notification_system.py (159 lines)
• examples.py (238 lines)
• API_DOCUMENTATION.md (318 lines)
• IMPLEMENTATION_SUMMARY.md (167 lines)
• .gitignore

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• moulongzhang.github.io
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
