LinkCart (Datapack v5)

LinkCart is a Minecraft survival-friendly datapack (version 1.21+) that allows you to chain multiple minecarts together into a single, fully functional train led by a Furnace Minecart.

Using an advanced breadcrumb movement system, wagons accurately follow the leader through sharp turns, slopes, and long tracks without overlapping or decoupling bugs.

🌟 Key Features

• Chain Coupling: Connect minecarts sequentially in survival mode using leads (ropes). Simply click the Furnace Minecart (locomotive) to start, then click each wagon in order to build your train.

• Individual Uncoupling: Use Shears on any minecart to disconnect it or split the train at that exact point.

• Visual Lead Lines: Real-time visual particle strings show the active connections between wagons.

• Breadcrumb Movement System: Eliminates overlapping, decoupling on curves, or speed mismatch issues.

🚂 Locomotive Engine & Fuel Requirements

To launch and propel your train, the lead Furnace Minecart strictly requires solid fuel:

• Accepted Fuels: Coal, Charcoal, or Coal Blocks.

• Note: Fuel up the Furnace Minecart by interacting with it using your fuel of choice to ignite the engine and initiate movement along the track.

🚀 Quick Setup & Commands

After installing the datapack in your world folder, execute the following in-game:

1. Initialize / Reload:

   /reload
   

2. Enable Visual Indicators / Debug Mode:

   /function tren:debug_on
   

3. Disable Visual Indicators / Debug Mode:

   /function tren:debug_off
