EasyDupe is a lightweight server-side/client-side Fabric mod designed for Minecraft. It introduces a simple, redstone-friendly mechanism to duplicate Shulker Boxes using pistons and End Rods.
Place a Shulker Box (it can be filled with items/diamonds—NBT data is fully preserved!).
Place an End Rod adjacent to the target position where the Shulker Box will be pushed.
Push the Shulker Box into the End Rod using a Piston.
When the Shulker Box breaks upon hitting the End Rod, it drops 2x Shulker Boxes with all internal contents intact.
NBT / Inventory Data Preservation: Items inside the Shulker Box (diamonds, tools, resources) are copied perfectly without data loss.
Fabric API Powered: Smooth integration with modern Fabric event lifecycles.
Server-Side Handled: Built to ensure accurate item entity replication without client-side ghost item glitches.
Lightweight & Clean: Zero performance impact on your world ticks.
