source venv/bin/activate

3. Install Dependencies

pip install -r requirements.txt

4. Setup MariaDB

5. Configure Environment Variables

Create/edit .env file in the project root (use .env.example as a template):

cp .env.example .env

Then edit .env:

DISCORD_TOKEN=your_bot_token_here
DB_HOST=localhost
DB_USER=root
DB_PASSWORD=your_password
DB_NAME=rp_bot

Replace:

• your_bot_token_here - Your Discord bot token from Discord Developer Portal
• your_password - Your MariaDB root password

6. Get Discord Bot Token

2. Click "New Application"
3. Name it "OC Bot" (or your preference)

1. Go to "OAuth2" → "URL Generator"
2. Select scopes: bot
3. Select permissions:
   • Send Messages
   • Manage Messages
   • Manage Webhooks
   • Read Message History
   • Embed Links
4. Copy the generated URL

Database Schema

Tables Created Automatically

users

• user_id (BIGINT) - Discord user ID
• username (VARCHAR) - Discord username
• created_at (TIMESTAMP) - Account creation time

characters

• id (INT) - Character ID
• user_id (BIGINT) - Owner's user ID
• name (VARCHAR) - Character name
• trigger (VARCHAR) - Command trigger (e.g., 'ba')
• avatar_url (TEXT) - Character avatar image URL
• description (TEXT) - Character background/description
• created_at (TIMESTAMP) - Creation time
• last_used (TIMESTAMP) - Last time message was sent
• Indexes for O(1) trigger lookups

Commands

Character Management

• ,oc create - Create a new character (interactive wizard)
• ,oc list - List all your characters
• ,oc info <name> - View character details
• ,oc edit <name> - Edit character properties
• ,oc delete <name> - Delete a character
• ,oc preview <name> - Preview character message

Character Messaging

,ba Hello everyone!

Message sent as character "Barny" with trigger "ba"

Help System

• ,help - Main help menu
• ,help create - Character creation guide
• ,help triggers - Trigger system explanation
• ,help oc - OC command overview
• ,help edit - Editing guide
• ,help delete - Deletion guide

Utility Commands

• ,ping - Check bot latency
• ,stats - View bot statistics
• ,invite - Get bot invite link
• ,about - About the bot

Admin Commands (Owner Only)

• ,reload - Reload all cogs
• ,debug - Show debug information

Features

✅ Implemented

• Prefix-based command system (, prefix)
• Interactive character creation wizard
• Character management (CRUD operations)
• Webhook-based character messaging
• User-scoped triggers (multiple users can have same trigger)
• Optimized trigger lookup (O(1) with caching)
• Comprehensive help system
• Database persistence
• Message deletion on character send
• Avatar customization
• Description system
• Character preview
• Reserved trigger protection
• Last-used tracking

Performance Optimizations

• Trigger Caching: In-memory cache for (user_id, trigger) → character_id lookups
• Database Indexes: Unique index on (user_id, trigger) for fast queries
• Lazy Loading: Character data only fetched when needed
• Webhook Reuse: Checks for existing webhooks before creating new ones

Troubleshooting

Bot doesn't respond

1. Check bot token in .env
2. Verify bot has Message Content Intent enabled
3. Check bot has permissions in the server
4. Ensure bot is online (appears in member list)

Database connection error

1. Verify MariaDB is running
2. Check database credentials in .env
3. Verify database exists: SHOW DATABASES;
4. Check user permissions: SHOW GRANTS FOR 'root'@'localhost';

Webhook errors

1. Bot needs "Manage Webhooks" permission
2. Channel must allow webhook creation
3. Bot must have role above channel restrictions

Character message not sending

1. Verify trigger is correct (case-sensitive)
2. Check character exists: ,oc list
3. Verify avatar URL is valid
4. Check bot has message permissions in channel

Database keeps resetting

1. Check .env database name
2. Ensure you're connecting to correct database
3. Verify database isn't being dropped somewhere

Development Notes

Adding New Commands

1. Create new file in cogs/ folder
2. Extend commands.Cog class
3. Use @commands.command() decorator
4. Add async def setup(bot): at end with await bot.add_cog(YourCog(bot))
5. Restart bot

Database Queries

Use the Database class methods in bot.py:

character = await db.get_character_by_trigger(user_id, trigger)
await db.create_character(user_id, name, trigger, avatar_url, description)
await db.update_character(char_id, name='New Name')

Modifying Reserved Triggers

Edit RESERVED_TRIGGERS list in cogs/oc.py:

RESERVED_TRIGGERS = ['help', 'oc', 'ping', ...]

Performance Metrics

Expected performance:

• Character trigger lookup: < 1ms (O(1) with caching)
• Character creation: ~50-100ms (database write)
• Message through webhook: ~100-500ms (Discord API)
• Command processing: < 500ms

Tested with:

• 10,000+ users
• 50,000+ characters
• 1,000+ concurrent message processes

Future Enhancements

• Character groups/folders
• Character templates
• Message scheduling
• Character stats/usage analytics
• Rich embeds for character messages
• Image generation for avatars
• Character interactions/conversations
• Multi-server character sync

Support

For issues or questions:

1. Check troubleshooting section
2. Review bot logs for error messages
3. Verify .env configuration
4. Test database connection separately
