## Setup Guide

### 1. VRChat Configuration
1. Enable OSC in VRChat settings
2. VRChat listens on port 9000 (default)
3. VRChat sends on port 9001 (default)

### 2. Plugin Configuration
1. Open OSC-Bridge settings in the dashboard
2. Enable the bridge
3. Configure ports (default: send 9000, receive 9001)
4. Click "Save Configuration"

### 3. Gift Mappings
1. Navigate to "Gift Catalogue Mappings" section
2. **Option A - Use Gift Catalogue (Recommended):**

   - Gift ID and Name will be auto-filled
3. **Option B - Manual Entry:**
   - Enter Gift ID and/or Gift Name manually
   - Useful for custom gifts or if catalogue is not available
4. Select the action to trigger (wave, celebrate, dance, hearts, confetti, emote, avatar, custom_parameter)
5. Configure parameters (duration, slot, avatar ID, parameter name, etc.)
6. Click "Add Mapping"
7. Repeat for all desired gift mappings
8. Click "Save Mappings" when done

**Note:** The gift catalogue integration automatically populates gift names and IDs from your TikTok stream, making it easier to create accurate mappings without manually looking up gift IDs.

3. Copy the avatar ID (format: `avtr_xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`)

### Method 2: VRCLens Tool
1. Install VRCLens from VRChat community tools
2. Look up your avatars
3. Copy the avatar ID from the tool

### Method 3: VRChat Website
1. Go to vrchat.com and login
2. Navigate to your avatars
3. Click on an avatar
4. The ID is in the URL

## Troubleshooting

### OSC Bridge won't start
- Check if VRChat is running
- Verify ports are not in use by another application
- Check firewall settings
- Try different port numbers

### Gift mappings not triggering
- Ensure OSC-Bridge is running
- Verify gift IDs match TikTok gift IDs
- Check verbose logs for incoming gifts
- Confirm VRChat has OSC enabled

### Avatar switching not working
- Verify avatar ID is correct (starts with `avtr_`)
- Ensure you own the avatar or it's public
- Check VRChat OSC is enabled
- Try manual OSC test first

### No response from VRChat
- Check VRChat OSC is enabled in settings
- Restart VRChat
- Check firewall is not blocking UDP ports
- Try sending test signal from UI

## Security Notes

- Only local IP addresses are allowed (127.0.0.1, ::1, localhost)
- OSC traffic is not encrypted (local network only)
- Gift mappings are stored in plugin configuration
- Avatar IDs are not sensitive but should be from trusted sources
