StringDuperFixRestorer

StringDuperFixRestorer
A simple Paper plugin that brings back string duper behavior — even after Mojang patched it.
Great for technical Minecraft servers that rely on redstone contraptions or want to re-enable string farming.

Features

• Restores string duping (based on old tripwire mechanics)
• Only works under specific conditions, mimicking how dupers used to behave
• Uses flowing water, tripwire hooks, and tripwire like old duper designs
• Automatically replaces and breaks string for continuous output

How It Works

• When tripwire is attached between two tripwire hooks and flowing water (not source) is directly beneath:
  • The string breaks, drops one item
  • It's replaced automatically
  • Then breaks again after a short delay
• This cycle creates a loop similar to historical dupers

Requirements

• Minecraft 1.21.8
• A Paper-based server
• Java 17+

Installation

1. Drop the .jar into your server's plugins/ folder
2. Restart the server
3. Use /stringdupe enable in a chunk where your duper is located

Configuration
No config file required

Tested On

• Paper 1.21.8
• Local Multiplayer server
• Public Multiplayer with multiple dupers
