Major Implementation Complete: Account/Character System

Date: November 9, 2025
Status: ✅ BACKEND COMPLETE - Frontend Pending

🎉 What Was Implemented

1. Database Migration ✅

  • New Tables Created:

    • accounts - Authentication and account management
    • characters - Game characters (1-10 per account)

  • Migration Results:

    • ✅ 5 existing players migrated to accounts + characters
    • ✅ All foreign keys updated (inventory, combats, equipment, etc.)
    • ✅ Old players table dropped
    • ✅ Indexes optimized for new schema

2. Authentication System Refactor ✅

  • Email-Based Auth: Login/register now use email instead of username
  • JWT Tokens Updated: Include both account_id and character_id
  • Character Selection Required: Must select character after login

New Endpoints:

POST /api/auth/register - Register with email
POST /api/auth/login - Login with email
GET /api/characters - List all characters for account
POST /api/characters - Create new character (with stat allocation)
POST /api/characters/select - Select character to play
DELETE /api/characters/{id} - Delete character

3. Character System Features ✅

  • Multi-Character Support: 1 character for free, 10 for premium

  • Character Creation:

    • Unique name requirement (validated)
    • 20 stat points to distribute (strength/agility/endurance/intellect)
    • Calculated HP/stamina based on endurance
    • Avatar support (placeholder for now)

  • Premium Restrictions Enforced:

    • Free accounts: 1 character maximum
    • Premium accounts: 10 characters maximum

4. Database Schema Changes ✅

Accounts Table:

- id (PRIMARY KEY)
- email (UNIQUE, NOT NULL)
- password_hash
- steam_id (UNIQUE, for future Steam integration)
- account_type ('web' or 'steam')
- premium_expires_at (NULL = free, timestamp = premium end)
- created_at, last_login_at

Characters Table:

- id (PRIMARY KEY)
- account_id (FK to accounts)
- name (UNIQUE, character name)
- avatar_data (JSON for avatar customization)
- level, xp, hp, max_hp, stamina, max_stamina
- strength, agility, endurance, intellect, unspent_points
- location_id, is_dead, last_movement_time
- created_at, last_played_at

Updated Foreign Keys:

  • inventory.character_id (was player_id)
  • active_combats.character_id (was player_id)
  • pvp_combats.attacker_character_id & defender_character_id
  • equipment_slots.character_id
  • player_status_effects.character_id
  • player_statistics.character_id

📋 Current State

What Works ✅

  1. Registration: POST /api/auth/register with email + password
  2. Login: POST /api/auth/login returns account + character list
  3. Character Creation: Full stat allocation system working
  4. Character Selection: Select character to play
  5. Character Deletion: Delete unwanted characters
  6. Premium Enforcement: Free users limited to 1 character
  7. Old Player Data: All 5 existing players successfully migrated
