About String Duper
From ModrinthStringDuper restores classic tripwire string duping in Minecraft using a controlled tick-based system. Farms only run when the setup, water, and conditions are valid, with safety checks that reduce lag and prevent accidental activation.

StringDuper
StringDuper is a server-friendly string duplication system designed for stable and predictable farming. It uses structure validation and optimized server-side processing to maintain consistent behavior while reducing unnecessary entity and physics load.
The system is designed for multiplayer servers and supports multiple farms while preventing invalid, overlapping, or excessively dense setups.

Limitations
- A player must remain within 64 blocks for farms to stay active
- Tripwire chains must remain fully attached
- Maximum chain distance is limited
- Invalid or incomplete structures are automatically disabled
- Overlapping or intersecting farms are blocked
- Correct hook, trapdoor, lever, and water placement is required
- Excessive farm stacking is prevented
