StringDuper

StringDuper transforms string farming into a stable, optimized, and multiplayer-friendly mechanic using deterministic server-side processing, strict structure validation, and smart farm management systems.

Instead of relying on unstable vanilla duplication behavior, the mod provides a cleaner and more scalable farming experience focused on predictable behavior, reduced lag, optimized item spawning, and safer long-term multiplayer performance.

StringDuper preserves the gameplay feel of traditional string dupers while improving stability, scalability, and overall server performance.

Features

Deterministic server-side farm processing
Optimized stacked 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 system
Reduced entity and physics lag
Cached farm validation system
Event-assisted hook tracking
Silent production behavior with 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 to reduce spam
Farms generate output every 20 ticks (1 second)

All default configuration values can be changed inside:

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

( We advise against making changes to the JSON file unless it is necessary )

Limitations

Farms require players within a 64-block radius to remain active
Tripwire chains must remain fully attached
Maximum chain distance is limited
Invalid or incomplete structures are automatically suppressed
Overlapping or intersecting farms are blocked
Farms require proper hook, trapdoor, lever, and water placement
Excessively dense farm stacking is prevented
Farms only operate while the structure remains fully valid

Warning

Overlapping or intersecting farms are intentionally suppressed
Breaking tripwire structure integrity immediately disables the farm
Extremely large-scale farm abuse may still impact server performance
Debug mode should remain disabled during normal production gameplay
