Using Worldedit

Using WorldEdit

When to Use WorldEdit vs Schematics

Rule of thumb: WorldEdit for bulk/terrain, Schematics for detailed structures.

WorldEdit via Client Bridge

Commands execute as the local player through the Fabric client bridge.

Key Rules:

• ✅ Use // prefix for WorldEdit commands
• ✅ Comma-separated coordinates: //pos1 100,64,200
• ❌ Never use execute as wrappers
• ⛔ NEVER teleport the player

Selection Commands

//pos1 100,64,200      # First corner
//pos2 120,80,220      # Second corner
//expand 5 up          # Expand up
//expand vert          # Full height
//contract 3 north     # Shrink from north
//shift 10 east        # Move selection
//inset 2              # Shrink all sides
//outset 3             # Expand all sides
//sel cuboid|sphere|cyl|poly  # Selection mode
//size                 # Show size

Region Commands

//set stone                       # Fill selection
//set 50%stone,50%cobblestone     # Random mix
//replace dirt grass_block        # Replace blocks
//walls stone                     # Only walls
//faces stone                     # All 6 faces
//hollow                          # Remove interior
//move 10 up                      # Move selection
//stack 5 north                   # Stack copies

Generation Commands

//sphere stone 10      # Solid sphere r=10
//hsphere stone 10     # Hollow sphere
//cyl stone 5 10       # Cylinder r=5 h=10
//hcyl stone 5 10      # Hollow cylinder
//pyramid stone 15     # Pyramid
//generate stone (x*x+y*y+z*z)<100  # Expression

Terrain Commands

//smooth 3             # Smooth terrain
//naturalize           # Add dirt/stone layers
//flora 10             # Add flowers/grass
//forest 20 oak        # Generate forest
//drain 10             # Remove water/lava
//fixwater 10          # Fix water flow

Clipboard Commands

//copy                 # Copy selection
//cut                  # Copy + clear
//paste                # Paste at player
//paste -a             # Paste, skip air
//rotate 90            # Rotate clipboard
//flip north           # Mirror clipboard

Patterns

stone                             # Single block
50%stone,50%cobblestone           # Random percentage
oak_stairs[facing=north]          # With block state

Masks

-m stone              # Only affect stone
-m !air               # Exclude air
-m stone,cobble       # Multiple blocks

Common Workflows

Terrain Prep for Building

build(commands=[
    "//pos1 100,60,200",
    "//pos2 150,70,250",
    "//set grass_block",
    "//smooth 2"
], description="Flatten area")

Create Platform

build(commands=[
    "//pos1 100,64,200",
    "//pos2 120,64,220",
    "//set stone_bricks"
], description="Stone platform")

Forest Generation

//pos1 100,64,200
//pos2 200,64,300
//forest oak 5

Large Sphere

//pos1 95,70,195      # Center - radius
//pos2 115,90,215     # Center + radius
//sphere stone 10

Using build() for WorldEdit

build(commands=[
    "//pos1 100,64,200",
    "//pos2 120,80,220",
    "//set stone_bricks",
    "//walls oak_planks",
    "//hollow"
], description="Basic shell")

⛔ Commands That DON'T Work via RCON

Brushes (require player click):

❌ //br sphere stone 5
❌ //br cyl stone 3 1
❌ //brush smooth 3

Tool bindings (require held item):

❌ //tool tree
❌ //tool info

Alternatives for trees:

✅ //forest oak 5        # Selection-based
✅ //forestgen 50 oak 5  # Standalone

History

//undo                 # Undo last
//redo                 # Redo
//undo 5               # Undo 5 actions

After WorldEdit: Add Details with Schematics

Typical workflow:

1. Use WorldEdit to prepare terrain and create bulk structure
2. Use build_schematic() to add doors, stairs, furniture, details

# Step 1: WorldEdit for bulk
build(commands=[
    "//pos1 100,64,200",
    "//pos2 120,68,220",
    "//set oak_planks",
    "//hollow"
], description="House shell")

# Step 2: Schematic for details
build_schematic(
  schematic={
    "anchor": [100, 64, 220],  # South wall
    "palette": {
      "Dl": "oak_door[facing=south,half=lower]",
      "Du": "oak_door[facing=south,half=upper]",
      "W": "oak_planks"
    },
    "layers": [
      {"y": 1, "grid": [["W", "Dl", "W"]]},
      {"y": 2, "grid": [["W", "Du", "W"]]}
    ]
  },
