✂️ Layer Pack | Optimize resource pack sending

PackLayer
Proxy Resource Pack Optimization for BungeeCord & Velocity

By the developer of Oraxen

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚡ The Problem

When players switch between backend servers on your network, each server sends its resource pack request. If multiple servers use the same pack, the client is forced to re-download and re-apply it on every switch. This causes unnecessary loading screens, wasted bandwidth, and poor player experience.

✨ The Solution

PackLayer intercepts outgoing resource pack packets at the proxy level and cancels duplicates. If a player already has a pack with a matching hash, the packet is dropped, making server switching instant.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Features

• Smart Duplicate Detection: Skip packs by hash, URL, or both
• Server Filtering: Whitelist or blacklist specific backend servers
• Trusted Domains: Auto-skip packs from trusted CDNs
• Grace Period: Optional delay after server switch
• Statistics Tracking: See packs skipped and bandwidth saved
• Zero Dependencies: Everything bundled in one jar
• Lightweight: Less than 1ms latency per check

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Installation

1. Download the jar
2. Place it in your proxy's plugins folder (Velocity or BungeeCord)
3. Restart your proxy
4. Done!

Note: This is a proxy plugin. It goes on Velocity/BungeeCord, not Paper/Spigot.
