Velocitypacker

A Velocity plugin that automatically sends resource packs to players and stores their acceptance status in a SQLite database.

✨ Features

• 🔄 Automatic Resource Pack Sending - Pack is sent on every proxy join
• 📊 SQLite Database - Persistent storage of acceptance status
• 🚫 Smart Blocking - Players cannot connect to servers until pack is accepted/declined
• ⚡ Auto-Connect - Automatic connection to first server after successful acceptance
• 🔒 Session Management - No re-sending when switching between backend servers
• 🎛️ YAML Configuration - Easy customization of all settings
• 📋 Detailed Logs - Comprehensive information about pack status

🚀 Installation

1. Download Plugin

# Clone repository
git clone https://github.com/TheLion102009/Velocitypacker.git
cd Velocitypacker

# Build plugin
./gradlew clean shadowJar

2. Install JAR

You can find the compiled JAR in build/libs/Velocitypacker-0.1.jar.

Copy this file to the plugins/ folder of your Velocity server.

3. Start Server

Restart your Velocity server. The configuration file will be created automatically.

⚙️ Configuration

The config.yml is automatically created in the plugins/velocitypacker/ folder:

# Resource pack URL (REQUIRED)
# Must be a direct download URL to a .zip file
resourcePackUrl: https://example.com/resourcepack.zip

# SHA-1 hash of the resource pack (OPTIONAL)
# Format: 40 hexadecimal characters (e.g. a1b2c3d4e5f6...)
# Leave empty if you don't want to use a hash
resourcePackSha1: ""

# Message shown to the player
# Supports Minecraft color codes with §
resourcePackPrompt: "§aPlease accept the resource pack to play!"

# Kick player if the resource pack is declined
kickOnDecline: true

# Kick player if the download fails
kickOnFailedDownload: true

# Kick message (supports color codes with §)
kickMessage: "§cYou must accept the resource pack to play!"

Generate SHA-1 Hash

Windows:

certutil -hashfile resourcepack.zip SHA1

Linux/Mac:

sha1sum resourcepack.zip

🔧 How It Works

Player Join Process:

1. Player connects to proxy → Resource pack is sent immediately
2. Server connection blocked → Player stays in resource pack screen
3. Pack accepted → Automatic connection to first available server
4. Pack declined → Player is kicked (if configured)

Server Switch Process:

• Backend server switch → No re-sending (stored in session)
• Proxy rejoin → Pack is sent again (new session)

Database:

• Location: plugins/velocitypacker/resourcepack.db
• Stored data: UUID, acceptance status, timestamp
