Discord Custom Activity - Auto RPC

A fully automated Discord Rich Presence system that displays custom lyrics and animations, automatically starting when Discord launches and stopping when Discord closes.

🎵 Features

• Auto-Start/Stop: Automatically runs when Discord opens and stops when Discord closes
• Lyrics Display: Shows song lyrics in a flowing 2-line format
• Silent Operation: Runs completely in the background with no popup windows
• Smart Timing: 10-second delay for Discord to fully load before starting RPC
• Error Recovery: Automatically restarts if the RPC crashes
• Multi-Discord Support: Works with Discord Stable, Canary, PTB, and Development versions

🚀 Quick Setup

1. Prerequisites

• Python 3.6+ installed and added to PATH
• Discord Developer Application created at https://discord.com/developers/applications
• Get Client ID and add to rpc.py

2. Install Dependencies

The required packages (psutil and pypresence) will be auto-installed when you first run the monitor.

Or install manually:

pip install psutil pypresence

3. Auto-Start Setup

For automatic startup with Windows:

1. Press Win + R, type shell:startup, press Enter
2. Copy start_discord_monitor.bat to the Startup folder
3. Restart your computer

For manual testing:

• Double-click start_discord_monitor.bat

🎯 How It Works

Current Display Format

Details: "Lần Cuối - Ngọt" (Fixed song title)
State: "Nhìn quanh lần cuối" (Current lyric line)
Large Text: "Rừng thay lá ngậm ngùi" (Next lyric line - visible on hover)
Timer: Shows how long RPC has been running

Lyrics Flow

• 2-line pairs for better readability
• 4-second intervals between lyric changes
• Long sentences split (6+ words) for optimal display
• Continuous loop through all lyrics

Process Flow

1. Monitor starts when Windows boots
2. Waits for Discord to launch
3. 10-second delay for Discord to fully load
4. Starts RPC with lyrics animation
5. Auto-stops when Discord closes
6. Auto-restarts if Discord reopens

⚙️ Customization

Change Lyrics

Edit the lyrics_pairs array in rpc.py:

lyrics_pairs = [
    ["Your first line", "Your second line"],
    ["Another line", "Next line"],
    # Add more pairs...
]

Adjust Timing

time.sleep(4)  # Change to 3, 5, 6 etc. for different speeds

Change Song Info

details="Your Song - Artist",  # Change song title
buttons=[
    {"label": "🎵 Your Song", "url": "your-youtube-link"}
]

Modify Images

large_image="your-image-url",     # Main image
small_image="your-small-image",   # Corner overlay

🛠️ Advanced Configuration

Discord Process Detection

The monitor watches for these processes:

• Discord.exe (Stable)
• DiscordCanary.exe (Canary)
• DiscordPTB.exe (Public Test Build)
• DiscordDevelopment.exe (Development)

📋 Troubleshooting

RPC Not Appearing

1. Check Discord Developer Console:

   • Go to https://discord.com/developers/applications
   • Verify your Client ID matches the one in rpc.py

2. Test RPC manually:

   cd "e:\codingStorage\Projects\custom-activity"
   python rpc.py

Monitor Not Working

1. Test monitor manually:

   python discord_monitor.py

2. Check file locations:

   • All files must be in the same folder
   • Batch file must have correct path to your folder

High Resource Usage

• Monitor checks every 3 seconds (minimal CPU usage)
• RPC updates every 4 seconds (Discord's limit is 15 seconds)

🔧 File Details

rpc.py

• Main Discord RPC script
• Contains lyrics and display logic
• Handles graceful shutdown
• 10-second startup delay

discord_monitor.py
