source: manual

reasoning: Player wants a solid stone sphere with radius 10. WorldEdit command: //sphere <block> <radius>. This creates a filled sphere at the player's position.

difficulty: easy

extracted_from: manual WorldEdit reference


reasoning: Hollow sphere uses //hsphere. The 'h' prefix means hollow.


reasoning: Fill the current WorldEdit selection with stone. The command is //set <block>. Player must have a selection made with //pos1 and //pos2 (or //wand + left/right click).

message: Make sure you have a WorldEdit selection first. Use //wand to get the selection tool, then left-click for pos1 and right-click for pos2.


user_message: replace all dirt with grass in my selection

reasoning: Replace blocks within selection. //replace <from> <to>. Replaces dirt blocks with grass_block.


reasoning: Replace stone with air effectively removes all stone in the selection.


reasoning: Copy the current selection to clipboard. //copy stores it relative to the player's position.

message: Selection copied to clipboard. Use //paste to place it. The paste position is relative to where you stood when copying.


reasoning: Paste from clipboard at current position. //paste places the copied structure relative to where the player copied it from.


reasoning: Undo the last WorldEdit operation. //undo reverses the most recent change.


reasoning: Redo a previously undone WorldEdit operation.


user_message: build a stone cylinder radius 5 height 10

reasoning: Solid cylinder: //cyl <block> <radius> <height>. Creates a filled cylinder.


user_message: build a hollow cylinder of glass radius 8 height 20

reasoning: Hollow cylinder: //hcyl <block> <radius> <height>. Only the walls, no fill inside.


user_message: make walls around my selection with stone bricks

reasoning: //walls creates the 4 vertical sides of the selection. Does not fill top/bottom.


user_message: enclose my selection with glass on all sides

reasoning: //faces fills all 6 faces (walls + top + bottom) of the selection. This is like //walls but also covers ceiling and floor.


reasoning: Explaining WorldEdit selection methods.

message:
WorldEdit selection methods:
1. //wand -- gives you a wooden axe. Left-click a block to set pos1, right-click to set pos2.
2. //pos1 -- sets pos1 to your current position
3. //pos2 -- sets pos2 to your current position
4. //hpos1 -- sets pos1 to the block you're looking at
5. //hpos2 -- sets pos2 to the block you're looking at

The selection is the cuboid between pos1 and pos2. Use //expand and //contract to adjust the selection size.


reasoning: //expand <amount> <direction>. Direction 'up' expands upward.


user_message: contract my selection 5 blocks from the north

reasoning: //contract <amount> <direction>. Shrinks the selection from the specified side.


reasoning: //stack <count> <direction>. Repeats the selection content in the specified direction.


reasoning: //drain <radius> removes water (and lava) in a radius around the player.


reasoning: //snow <radius> adds snow layers to exposed surfaces. Simulates snowfall.


reasoning: //thaw <radius> removes snow and ice from surfaces. Opposite of //snow.


reasoning: //regen regenerates the selected area back to the original world generation. Warning: this is destructive and removes all player-placed blocks.

message: Warning: //regen will replace everything in your selection with the original world-generated terrain. All player builds in the selection will be lost.


reasoning: //cut copies the selection to clipboard and replaces it with air. Like copy + delete.

message: Selection cut to clipboard (replaced with air). Use //paste to place it elsewhere, or //undo to restore.


reasoning: Common mistake: there is no '//fill' command in WorldEdit. The correct command to fill a selection is //set. The Minecraft /fill command is different from WorldEdit.

message: Note: WorldEdit uses //set to fill a selection, not //fill. The /fill command is a vanilla Minecraft command (different from WorldEdit).

error: '//fill' is not a WorldEdit command. Use '//set stone' to fill your selection, or vanilla '/fill' with coordinates.

reasoning: General WorldEdit overview for beginners.

message:
WorldEdit basics:
1. Get the wand: //wand (gives wooden axe)
2. Select area: Left-click = pos1, Right-click = pos2
3. Fill selection: //set <block>
4. Replace blocks: //replace <from> <to>
5. Copy/paste: //copy then //paste
6. Undo mistakes: //undo
7. Build shapes: //sphere, //cyl, //hsphere, //hcyl
8. Walls only: //walls <block>

All WorldEdit commands use // prefix (double slash), not single /. The selection is always the cuboid between pos1 and pos2.


reasoning: //wand gives the player a wooden axe that serves as the selection tool.


reasoning: //set air clears the entire selection. This is destructive.

message: This will clear everything in your selection. Use //undo if you need to revert.


reasoning: A dome is a hollow sphere. //hsphere glass 15 creates a hollow sphere. For just the top half (dome), the player should stand at the base level. WorldEdit's //hsphere generates a full sphere, but if the player stands on the ground, the bottom half goes underground which effectively creates a dome above.

message: Stand at the base level where you want the dome. The sphere will generate around you -- the top half forms the dome. If you only want the upper hemisphere, you can //undo and instead use //hsphere glass 15 while standing at the intended floor level.

difficulty: medium


reasoning: WorldEdit brush tool: //brush sphere <block> <radius>. Binds a sphere brush to the held item. Right-clicking with the item places a sphere at the targeted block.

message: Sphere brush bound to your held item with radius 3 (stone). Right-click to place spheres at the targeted block. Change radius/block by re-running the command. Use //brush none to unbind.


user_message: replace all water with air in my selection

reasoning: //replace water air removes all water blocks in the selection.


user_message: build a pyramid of sandstone 10 blocks tall

reasoning: //pyramid <block> <size>. Creates a solid pyramid. Size is the base-to-peak height.


user_message: build a hollow pyramid of quartz 15 high

reasoning: //hpyramid <block> <size> creates a hollow pyramid.


reasoning: Common mistake: using single / instead of //. WorldEdit commands all require double slash //.

message: Note: WorldEdit commands use // (double slash), not / (single slash). The correct command is //set stone.

error: WorldEdit commands require // (double slash). '/set' is not recognized. Use '//set stone'.


reasoning: //smooth <iterations> smooths the terrain heightmap in the selection. More iterations = smoother.

message: Smoothing terrain with 3 iterations. Increase the number for a smoother result.


reasoning: //rotate <degrees> rotates the clipboard. Valid values: 90, 180, 270. Must have something copied first.

message: Clipboard rotated 90 degrees. Use //paste to place the rotated version.


reasoning: //flip up flips the clipboard vertically (upside down).

message: Clipboard flipped vertically. Use //paste to place it.


reasoning: //size shows the dimensions and block count of the current selection.


user_message: count how many diamond ore blocks are in my selection

reasoning: //count <block> counts how many of a specific block type are in the selection.


reasoning: //forest <type> <density> generates trees in the selection. Tree types: oak, birch, spruce, jungle, acacia, dark_oak.

message: Generating oak forest with 5% density in your selection. Adjust density (1-100) for more or fewer trees.


user_message: set my selection to a mix of stone and cobblestone

reasoning: WorldEdit supports block patterns with percentages. //set 50%stone,50%cobblestone creates a random mix.


reasoning: A ring is a hollow cylinder with height 1. //hcyl <block> <radius> 1.


user_message: worldedit select everything 50 blocks around me

reasoning: Set positions relative to player. //pos1 and //pos2 set to current position. Then //expand to grow the selection. Or use //sel with the 'sphere' selection mode. Simplest approach: set pos1, expand outward.

message: Selection created at your position and expanded 50 blocks in all directions. This selects a 100x100x100 area centered on you.


reasoning: //naturalize replaces the top layer with grass, the next 3 layers with dirt, and everything below with stone. Makes terrain look natural.


user_message: build a giant tower 5 blocks wide 50 blocks tall with stone bricks

reasoning: A tower is essentially a hollow cylinder. //hcyl stone_bricks 2.5 50 (radius ~2.5 for 5 block diameter). Alternatively use //pos1, //pos2, and //walls for a square tower.

message: Built a hollow cylindrical tower of stone bricks, radius 3, height 50. For a square tower, make a selection and use //walls stone_bricks instead.


reasoning: //overlay <block> places a block on top of all exposed surfaces in the selection.


user_message: remove all entities in my worldedit selection

reasoning: //remove <type> <radius> or /remove can clear entities. For selection-based, use //butcher for mobs or //remove for items.

message: This removes dropped items. For killing mobs, use //butcher <radius>. For all entities, //butcher -a <radius>.
