Commands are typed into the chat, starting with /. Each command below says where it works; Party means every player on a party server may use it (staff may use every command anywhere). World edits work on finite worlds only, and one runs at a time — a second is refused until the first finishes.
Wherever a command takes a block, write its ID — shown on each block’s wiki page — optionally followed by a rotation and a color:
<ID>[:<rotation>][:<x>,<y>]
Cobblestone, OakPlanks, Water. Air means empty space.PosX, NegX, PosY, NegY, PosZ, NegZ, for blocks that can face a direction.Examples: Sand · Wool:1,5 · Terracotta:PosX · Wool:PosX:3,2.
Wherever a command (/fill, /tp) takes a coordinate, write a whole number, or ~ for your own position on that axis (where your head is). Either may be followed by whole numbers to add or subtract.
Examples: 12 · -4 · ~ · ~10 (ten past you) · ~-5 · ~+3-1 · 12+3.
Party only.
/fill <x1>,<y1>,<z1> <x2>,<y2>,<z2> <block> [<inside>]
~,~,~ is the block at your head. Coordinates outside the world are clamped to its bounds.Air to clear.Air makes the box hollow. Omitted, the whole box is block.Examples:
/fill -10,1,-10 10,5,10 Stone — a solid stone slab, 21×5×21, centered on the world’s origin./fill 0,1,0 0,64,0 Glass — a one-block glass pillar from the ground to y=64./fill -200,1,-200 200,40,200 Air — clear everything up to y=40 (corners beyond the edge are clamped, so oversized boxes are a handy “everywhere”)./fill 5,1,5 15,1,15 Wool:1,5 — a floor of wool in the palette color at column 1, row 5./fill 1,1,1 10,10,10 Cobblestone Air — a hollow cobblestone box./fill 1,1,1 10,10,10 Cobblestone Glass — a cobblestone box full of glass./fill ~,~,~ ~10,~-5,~10 Sandstone — a sandstone block 11×6×11 reaching down and out from your head.Party only.
/flood <block>
Air).Floods outward from where you stand, filling all the connected open space — it goes where the air goes and stops at walls.
Examples:
/flood Water — standing in a dug-out basin: fill it as a lake./flood Stone — standing in a cave: seal the whole cavity solid./flood Glass — standing in a walled room: fill the room only; the rest of the world is untouched because the walls stop the flood.Party only.
/replace <from> <to> [<percent>%]
Wool:1,5 replaces only that color of wool.Air to remove.0% to 100%: replace only that random share. Omitted means every match.Examples:
/replace Stone Cobblestone — every stone block becomes cobblestone./replace Grass Air 50% — remove about half the grass, scattered./replace Wool:1,5 Wool:8,8 — recolor one wool color to another; other colors are untouched.Party only.
/count <block>
/replace.Counts every matching block in the world and replies with the number.
Examples:
/count Water — how big is that lake, in blocks?/count Wool:1,5 — count only the wool of one color.Party only.
/shift [<x>,<y>,<z>]
-17,0,-17.Anything pushed past the world’s edge is lost — the world does not grow to fit.
Examples:
/shift 0,10,0 — raise the entire build ten blocks, e.g. to make room for a basement./shift 20,0,0 — slide everything twenty blocks along +X, away from the edge you have grown up against./shift — the default nudge of -17,0,-17.Party only.
/rotate <turns>
1 is 90°, 2 is 180°, 3 is 270°.The world’s footprint must be square (see /shape); an oblong world is refused, since a turned layer must map onto itself.
Examples:
/rotate 1 — turn the world a quarter turn./rotate 2 — turn the world to face the other way.Party only.
/tp <x> <y> <z>
Examples:
/tp 0 10 0 — to the middle of the world, ten blocks up./tp ~ ~20 ~ — straight up twenty blocks./tp 100 80 -40 — straight to a build across the map.Everywhere (finite worlds).
/shape
Prints the world’s current shape in the exact form /set_shape accepts, e.g. square 40 12 floor.
Party only.
/set_shape <square|circle> <radius> <height> <floor|nofloor>
1–255.0–255.Blocks left outside the new shape are lost.
Examples:
/set_shape square 40 12 floor — the standard sandbox arena./set_shape circle 100 64 floor — a big round world with headroom./set_shape square 30 30 nofloor — a void world for sky builds.Everywhere.
/time
Prints the time of day in the exact form /set_time accepts.
Party, or your own nest.
/set_time <time> [<day>,<night>]
0 to 1.Examples:
/set_time 0.5 — freeze the world at midday./set_time 0 — freeze it at the start of the day./set_time 0.5 10,5 — start at midday and cycle: ten-minute days, five-minute nights.Everywhere.
/precipitation
Prints where the weather is in its cycle, in the exact form /set_precipitation accepts.
Party, or your own nest.
/set_precipitation <time> [<on>,<off>]
0 to 1: rain or snow over the first half, heaviest at 0.25, and none over the second./set_time stops the day, even in a world whose rules cycle it.Examples:
/set_precipitation 0.25 — the heaviest it gets, for good./set_precipitation 0.75 — dry, for good./set_precipitation 0 2,10 — start it now: two minutes of weather, then ten without.Everywhere (finite worlds).
/save <name>
Snapshots the whole world — blocks, creatures and all — to the named file. You must be logged in.
Examples:
/save castle — save the world as castle./save castle-v2 — snapshots don’t overwrite each other unless you reuse the name.Everywhere (finite worlds).
/save_code
Prints the whole world as a block of text instead of saving it to a file — copy it, keep it anywhere, paste it back with /load. Useful for sharing a build outside the game.
Party only.
/load <name> · /load <nick>:<name> · /load <code>
/save_code, pasted directly.Overwrites the current world with the loaded one. You must be logged in to load files (pasted code works regardless).
Examples:
/load castle — restore your own save named castle./load ada:castle — load castle as saved by the player ada./load AAAA… — paste the output of a /save_code to restore it.Party only.
/spawn <creature> [<count>]
revenant, blocker, reckoner, architect, scout, miremoth, howler, wildboar, sheep, wolf, lynx, cow, horse.0–10; omitted spawns one.Conjures the creatures a few blocks in front of you.
Examples:
/spawn sheep — one sheep./spawn revenant 10 — a crowd of ten Revenants to fight.Party only.
/buff <kind> [<level>]
Speed, Health, Regen, Haste, Damage, Jump, Reach, Invis.-10 to 20 for most, -10 to 10 for Speed and Damage, 0 to 10 for Invis; omitted means the maximum. Negative levels weaken instead of strengthen; 0 clears the buff.Examples:
/buff Speed — full speed boost./buff Jump 5 — a moderate jump boost./buff Invis — vanish entirely./buff Speed 0 — remove your speed buff./buff Damage -10 — for the brave: hit as weakly as possible.Party only.
/buffs [<level>]
Sets every buff at once — all of /buff’s kinds except Invis — each clamped to its own range exactly as in /buff.
Examples:
/buffs — everything maxed./buffs 0 — clear all your buffs (invisibility, if any, stays).Party only.
/active
Prints statistics about the world’s edits — how many blocks differ from the generated world, and how much of it is busy updating.
/active near lists the edited blocks within a few meters of you.
Party only.
/cache
Prints statistics about the generated-terrain chunk cache of an infinite world — how many chunks are cached in each storage form, roughly what they weigh in memory, and how many are queued for generation. Finite worlds have no such cache.
