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.

Features

  • Deterministic server-side farm processing
  • Optimized item spawning
  • Smart overlap-aware farm detection
  • Side-by-side farm compatibility
  • Strict tripwire structure validation
  • Configurable active farm limits
  • 64-block player proximity activation
  • Reduced entity and physics lag
  • Cached farm validation
  • Event-assisted hook tracking
  • Optional debug mode
  • Multiplayer-safe farm management
  • Configurable spawn intervals and batch sizes
  • Lightweight tick-based processing

Default Configuration

  • Maximum active farms across the server: 32
  • Maximum active farms per world: 16
  • Unlimited per-player farms enabled by default
  • Debug mode disabled by default
  • Player feedback messages enabled
  • Warning messages are rate-limited
  • Farms generate output every 20 ticks (1 second)

Configuration files:

  • Mods: config/StringDuper.json
  • Plugins: plugins/StringDuper/StringDuper.json

> ⚠️ We recommend changing the configuration only when necessary.

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
  • Farms only operate while the structure remains valid

Warning

  • Overlapping or intersecting farms are intentionally disabled
  • Breaking the tripwire structure immediately disables the farm
  • Extremely large-scale farms may still affect server performance
  • Debug mode is recommended only for testing and troubleshooting
