Pumpkin WorldEdit Plugin

A WorldEdit-style plugin for the Pumpkin Minecraft server, written in Rust. Supports region selection, block operations, clipboard, undo, and schematic load/save in both Sponge (.schem) and Litematica (.litematic) formats.

Features

• Region selection — Set two corners with pos1 and pos2
• Block operations — Set, replace, walls, clear, hollow
• Clipboard — Copy and paste with relative positioning
• Undo — Restore the last block-modifying operation
• Schematics — Load and save structures from .schem (Sponge v2/v3) and .litematic (Litematica) files
• Per-player state (selection, clipboard, undo)
• Selection limit of 100,000 blocks to avoid server lag

Commands

All commands use the /we or /worldedit prefix.

Selection

Command	Description
/we pos1	Set position 1 at your feet
/we pos2	Set position 2 at your feet
/we size	Show selection dimensions

Region editing

Command	Description
/we set <block>	Fill selection with a block
/we replace <from> <to>	Replace one block type with another
/we walls <block>	Build walls on X/Z edges of selection
/we clear	Set all blocks in selection to air
/we hollow	Remove interior, keep walls

Clipboard & history

Command	Description
/we copy	Copy selection to clipboard
/we paste	Paste clipboard at your position
/we undo	Undo the last operation

Schematics

Command	Description
/we schem load <name>	Load a schematic into clipboard (.schem or .litematic)
/we schem save <name>	Save clipboard as a .schem file
/we schem list	List saved schematics
/we schem delete <name>	Delete a schematic file

Schematic files are stored in plugins/pumpkin-worldedit/schematics/. For load/delete you can use the name with or without extension (e.g. castle or castle.litematic).

Supported schematic formats

• Sponge Schematic (.schem) — Versions 2 and 3 (gzipped NBT, varint block data). Compatible with WorldEdit and many other tools.
• Litematica (.litematic) — Gzipped NBT with regions, packed long-array block states, and optional metadata (position/size fallbacks for compatibility).

Requirements

• Pumpkin server (built from source)
• Rust toolchain to build the plugin
• Permission pumpkin-worldedit:command.we (default: OP level 2)

Building

From the pumpkin-worldedit directory (or with path dependencies correct from the Pumpkin repo root):

cargo build --release

Output:

• Windows: target/release/pumpkin_worldedit.dll
• Linux: target/release/libpumpkin_worldedit.so
• macOS: target/release/libpumpkin_worldedit.dylib

Installation

1. Copy the built plugin into the Pumpkin server plugins/ folder.
2. Start or restart the server. The plugin will create plugins/pumpkin-worldedit/schematics/ on first load.

Usage examples

Basic region and paste:

/we pos1
/we pos2
/we set stone
/we copy
/we paste
/we undo

Load and paste a schematic:

/we schem load castle
/we paste

Save a selection as schematic:

/we pos1
/we pos2
/we copy
/we schem save my_build
