Commands

Commands are advanced functions activated by typing certain strings of text.

Usage
In a regular Minecraft client or the stand alone client, commands are entered via Minecraft's chat window, which is displayed by pressing the key (default) or  key. Using the key will also enter the forward slash that commands require as a prefix, so it is a useful shortcut. Pressing while entering commands cycles through possible commands or arguments.

Commands may also be entered in a multiplayer server's console, but are not preceded by a when entered this way. A server admin running commands in this way is often referred to as "ghosting".

Commands in command blocks can be preceded by a slash, but it is not required. Commands in a command block may also require an optional argument, usually a player's username.

The majority of commands are only available in the following situations:


 * In a Minecraft multiplayer server game, entered by an operator or command block.
 * In other multiplayer games, entered by the player who opened a LAN game with cheats enabled, or is hosting their own multiplayer server
 * In singleplayer, if cheats were enabled at world creation (via the "More World Options..." button).

Some player commands are also available in singleplayer even when cheats are not enabled.

Note: In singleplayer worlds where cheats were not enabled at creation, they can be enabled on a temporary basis by opening the current game session to LAN play ( → "Open to LAN", then "Allow Cheats" button and "Start LAN World"). You do not actually need to be on a LAN or have others join. This is not permanent, but will allow the use of commands until you quit the world, and changes you make via commands (items spawned, etc.) will be saved with the world. You can do this each time you start playing the world again. Note that this will disable game pausing for the duration, so while open to LAN, you should get somewhere safe or reload your world before using the Game Menu. Remember that you can disable your LAN world by reloading the world.

Tilde notation
Many commands allow relative coordinates to be specified using tildes. A number following a tilde is an offset from something rather than a coordinate. The sign of the offset specifies whether to go in the positive or negative direction for that axis. A single tilde by itself is shorthand for.

For example,  will teleport the user to the coordinate (0, 64, 0), while   will teleport the user to a position +3 blocks in the "x" direction (i.e., east), keep their current height, and -3 blocks in the "z" direction (i.e., north).

Usually absolute coordinates can be mixed with relative coordinates. For example,  will keep the user's "x" and "z" coordinates the same, but teleport them to absolute height of 64.

The origin for the offset depends on the command. For example, for the offset is from the starting position. Other common offsets include from the position of the command's execution or from another coordinate specified by the command.

Target selectors
In most commands where a player may be specified as an argument, it is possible to "target" one or more players satisfying certain conditions instead of specifying players by name. To target players by condition, choose a target selector variable and, optionally, one or more target selector arguments to modify the conditions to be satisfied.

For example, to change the game mode of all players on team Red to creative mode, instead of specifying them by name individually:

Target selector variables
A target selector variable identifies the broad category of targets to select. There are four variables:




 * Targets the nearest player. If there are multiple nearest players, caused by them being precisely the same distance away, the player who most recently joined the server is selected.


 * Target selector arguments may be used to reduce the set of players from which the nearest player will be selected. For example,  will target the nearest player on team Red even if there are other players closer.


 * The  target selector argument can be used to increase the number of nearest players targeted (for example,   will target the three nearest players). When negative,   will reverse the order of targeting (for example,   will target the farthest player).




 * Targets a random player (or entity with the  target selector argument).


 * Target selector arguments may be used to reduce the set of players from which a random player will be targeted. For example,  will only target a random player from team Red.


 * The  target selector argument can be used to increase the number of random players targeted. For example,   will target three random players.


 * When used without the  argument,   always targets a random player. The   argument can be used to target non-player entities (for example,   will target a random zombie,   will target a random non-player entity,   will target a random non-zombie, etc.).




 * Targets all players, including dead players. No other selector will find dead players.


 * Target selector arguments may be used to reduce the set of players targeted. For example,  will only target players on team Red.




 * Targets all entities (including players).


 * Target selector arguments may be used to reduce the set of entities targeted. For example,  will only target cows.

Target selector arguments
After using a target selector, you can optionally use arguments to modify the set of targets selected. When used with  or , arguments narrow down the number of targets from the full list to a specific few. When used with  or , arguments narrow the number of targets down from the full list to a smaller set from which the nearest or random player is selected.

Add argument-value pairs as a comma-separated list contained within square brackets after the target selector variable:



Spaces are not allowed around the brackets, equal signs, or commas, and only commas may be used to separate argument-value pairs.

Arguments are case-sensitive and unsupported arguments are silently ignored. For example,  will kill all creepers in a 20-block radius, but   (the 't' in 'type' capitalized) will kill all entities (including players) in that radius because there is no longer a valid argument limiting the targets to just creepers.

If the first few arguments (up to four) are specified simply as values without identifying the arguments, they are assumed to be, in order,,  ,  , and. Thus, the following two commands are identical:


 * Selecting targets by coordinate


 * — Selects targets based on distance to that exact position. Combine with selecting by radius to select only targets at that specific position.


 * The coordinates have to be integers and must be exact - tilde notation is not available for selector argument coordinates.


 * Selecting targets by radius


 * — Selects only targets less than R blocks from the command's execution.
 * — Selects only targets more than RM blocks from the command's execution.


 * If a coordinate (above) and either or both radius/i are both defined, the radius/i will center on the coordinate rather than the postion of the command's execution. By using a very distant coordinate and a very large radius, it is possible to simulate a near-linear edge to use to specify targets.


 * Selecting targets by game mode


 * — Selects only targets with the specified game mode. Permitted values for M are:
 * : all game modes
 * : survival mode
 * : creative mode
 * : adventure mode
 * : spectator mode
 * In, the following values will also be permitted:
 * , : survival mode
 * , : creative mode
 * , : adventure mode
 * , : spectator mode


 * Selecting targets by count


 * — Selects only the specified number of targets. Usually in order of distance from the command executor.


 * When used with  or , this argument defaults to 1, so using a higher number will increase the number of nearest or random targets returned. When used with   or  , this argument returns only the nearest targets.


 * If there are multiple nearest targets, caused by them being precisely the same distance away, targets are sorted by the time they have been on the server (since their most recent join for players or their creation for other entities) with the longest times selected first. For example, if equally distant,  will select the player who has been on the server the longest and   will select the three oldest creepers.


 * When used with a negative value, the order of targets is reversed. For example,  will return the three farthest targets, and, if all potential targets are equally far away,   will select the last three targets created.


 * Selecting targets by experience level


 * — Selects only targets with no more than L experience levels.


 * – Selects only targets with no less than LM experience levels.


 * Selecting targets by score


 * — Selects only targets with a score in objective name of no more than SCORE.


 * — Selects only targets with a score in objective name of no less than SCOREMIN.


 * For example,  will select all players with a score in objective "points" between 30 and 39 (inclusive).


 * Selecting targets by team


 * — Selects only targets on team TEAM.


 * — Selects only targets not on team TEAM.


 * — Selects only targets not on any team.


 * Selecting targets by name


 * — Selects only targets named NAME.


 * — Selects only targets not named NAME.


 * Selecting targets by volume




 * Selects only targets within the volume defined as starting from the location where the command was executed and extending DX blocks in the "x" direction (i.e., east/west), DY blocks in the "y" direction (i.e., upwards/downwards), and DZ blocks in the "z" direction (i.e., north/south). If an initial coordinate is specified with the,  , and   arguments, that will be used instead of the position of the command's execution for the lower northwestern corner ( ,  , and   still specify distances from that coordinate; they do not specify a separate coordinate).


 * It is possible to combine selection by radius and selection by volume, in which case the command will only select targets within the overlap of both regions (within certain radius/i of the volume's lower northwest corner and not outside the defined volume).


 * Selecting targets by vertical rotation


 * — Selects only targets with a maximum vertical rotation of RX.
 * — Selects only targets with a minimum vertical rotation of RXM.


 * Vertical rotation values vary from -90.0 facing straight up to 90.0 facing straight down (thus vertical rotation values increase with rotation downwards).


 * Selecting targets by horizontal rotation


 * — Selects only targets with a maximum horizontal rotation of RY.
 * — Selects only targets with a minimum horizontal rotation of RYM.


 * Horizontal rotation values vary from -180.0 (facing due north), to -90.0 (facing due east), to 0.0 (facing due south), to 90.0 (facing due west), to 179.9 (just west of due north) before wrapping back to -180.0 (thus horizontal rotation values increase with rotation to the right, or clockwise viewed from above).


 * Selecting targets by type


 * — Selects only targets of the specific entity type.
 * — Selects only targets not of the specific entity type.


 * TYPE must be an entity ID used to identify different types of entities internally (for example,  for creepers,   for regular minecarts,   for primed TNT, etc.). Entity IDs are case-sensitive and invalid entity IDs will cause the command to fail.


 * When used with, can change its normal behavior of targeting only players to target other entities.

Data tags
A data tag is a sequence of text which describes a data structure using attribute-value pairs. Data tags are used in commands to specify complex data for players, entities, and some blocks.

A data tag consists of zero or more attribute-value pairs separated by commas and delineated by curly brackets. Each attribute-value pair consists of an attribute name and the attribute's value, separated by a colon. Some values, however, may themselves contain attribute-value pairs, allowing a data tag to describe a hierarchical data structure.


 * Example:

The data structures that data tags describe are the same ones used in Minecraft's save files. These data structures are described in other articles and commands expect data tags to use the same attribute names (which are case-sensitive):

The defined data structures also expect the values to be of the correct type.

The type is unavailable to commands.

Some commands may require that a number's type be specified by adding a letter (B, S, L, F, D) to the end of the value. For example,  for a short,   for a float, etc. (This doesn't work with I for int.) The letter can be uppercase or lowercase. When no letter is used and Minecraft can't tell the type from context, it assumes double (if there's a decimal point), int (if there's no decimal point and the number is small enough to store as an int), or string (if neither is true). A square-bracketed literal is assumed to be an int array if every element that's between commas is an int; otherwise, it is assumed to be a list. An exception applies:  is an empty list, but   is an empty int array.

When commands such as, , and are used to match data tags, they only check for the presence of the provided tags in the target entity/block/item. This means that the entity/block/item may have additional tags and will still match. This is true even for lists and arrays: the order of a list is not acknowledged, and as long as every requested element is in the list, it will match even if there are additional elements.

The format used for data tags is a lenient form of JSON.

Raw JSON text
The and  commands use a specific [//google-gson.googlecode.com/svn/trunk/gson/docs/javadocs/com/google/gson/stream/JsonReader.html#setLenient%28boolean%29 lenient] JSON format to specify complicated text. Similar to the NBT format notation above, concepts such as Strings, Objects (Compounds), and Lists are used to represent the various properties of the raw text. In the 1.9 snapshots, commands use strict JSON syntax instead.

Scores and target selectors are evaluated for a Sign when it is placed or edited and for a Written Book when it is "resolved" (opened for the first time after signing). They won't update after that, and they won't work if edited onto an existing sign with an NBT editor, or onto a book that's already marked resolved. There's no way to wrap text onto the next line of a sign or the next page of a book during resolution; instead, the extra text will simply disappear.

The format of raw JSON text is a JSON Object which supports the following (mostly optional) elements:
 * The base chat component Object
 * : A string representing raw text to display directly in chat. Note that selectors such as "@a" and "@p" are not translated into player names; use selector instead. "\n" is newline (enter).
 * : A list of additional objects, sharing the same format as the base object.
 * A list element with the same format as the base object (recursive). Note that all properties of this object are inherited by children except for text, extra, translate, with, and score. This means that children will retain the same formatting and events as this object unless they explicitly override them.
 * : The color to render this text in. Valid values are "black", "dark_blue", "dark_green", "dark_aqua", "dark_red", "dark_purple", "gold", "gray", "dark_gray", "blue", "green", "aqua", "red", "light_purple", "yellow", "white", and "reset" (cancels out the effects of colors used by parent objects). Technically, "bold", "underline", "italic", "strikethrough", and "obfuscated" are also accepted, but it may be better practice to use the tags below for such formats.
 * : Boolean (true/false) - whether to render text in bold. Defaults to false.
 * : Boolean (true/false) - whether to render text underlined. Defaults to false.
 * : Boolean (true/false) - whether to render text in italics. Defaults to false.
 * : Boolean (true/false) - whether to render text with a strikethrough. Defaults to false.
 * : Boolean (true/false) - whether to render text obfuscated. Defaults to false.
 * : When the text is shift-clicked by a player, this string will be inserted in their chat input. It will not overwrite any existing text the player was writing.
 * : Allows for events to occur when the player clicks on text.
 * : The action to perform when clicked. Valid values are "open_url" (opens value as a URL in the player's default web browser), "open_file" (opens the value file on the users computer), "twitch_user_info" (opens info about a twitch user), "run_command" (has value entered in chat as though the player typed it themselves. This can be used to run commands, but the command will fail if the player does not have the required permissions to use it), "change_page" (can only be used in written books) changes to page value if that page exists, and "suggest_command" (similar to "run_command", but the text only appears in the player's chat input, and is not automatically entered. Unlike insertion, this will replace the existing contents of the chat input). "open_file" and "twitch_user_info" cannot be used with commands.
 * : The URL, file, twitch user, chat, command or book page used by the specified action. Note that commands must be prefixed with the usual "/" slash.
 * : Allows for a tooltip to be displayed when the player hovers their mouse over text.
 * : The type of tooltip to show. Valid values are "show_text" (shows raw JSON text), "show_item" (shows the tooltip of an item which can have NBT tags), "show_achievement" (shows formatted text describing an achievement or statistic. Normal achievement names are green, final achievement names are dark_purple, and statistic names are gray. In addition, a description is given for achievements), and "show_entity" (shows an entity's name, possibly its type, and its UUID).
 * : The formatting of this tag varies depending on the action. Note that "show_text" is the only action to support an Object as the value; all other action values are Strings and should thus be wrapped in quotes.
 * "show_text": Can be either a raw String of text, or an Object with the same formatting as this base object. Note that clickEvent and hoverEvent do not function within the tooltip, but the formatting and extra tags still work.
 * "show_item": A string formatted like item NBT data. Contains the "id" tag, and optionally the "Damage" tag and "tag" tag (which is the same compound used as "dataTag" in the command).
 * "show_achievement": The achievement or statistic's name. This uses the same format as achievement and statistic Scoreboard objective criteria and the command.
 * "show_entity": A string formatted like a compound with the string values "type" (such as "Zombie"), "name", and "id" (should be an entity UUID, but can actually be any string).
 * : The translation identifier of text to be displayed using the player's selected language. This identifier is the same as the identifiers found in lang files from assets or resource packs. The translated text will only be displayed if the text string is not used.
 * : A list of chat component arguments and/or string arguments to be used by translate.
 * The arguments are text corresponding to the arguments used by the translation string in the current language, in order (for example, the first list element corresponds to "%1$s" in a translation string).
 * : A player's score in an objective. Displays nothing if the player is not tracked in the given objective. Ignored completely if text or translate is present.
 * : The name of the player whose score should be displayed. Selectors (such as @p) can be used, in addition to "fake" player names created by the scoreboard system. In addition, if the name is "*", it will show the reader's own score (for example,  will show every online player their own score in the "obj" objective). Note that non-player entity scores (such as @e[type=Cow]) do not show, even if the entity has been given a score in the objective.
 * : The internal name of the objective to display the player's score in.
 * : Optional. If present, this value is used regardless of what the score would have been.
 * : A string containing a selector (@p,@a,@r, or @e) and, optionally, selector arguments. Unlike text, the selector will be translated into the correct player/entity names. If more than one player/entity is detected by the selector, it will be displayed in a form such as 'Name1 and Name2' or 'Name1, Name2, Name3, and Name4'. Ignored completely if text, translate, or score is present. Clicking a player's name inserted into a /tellraw command this way will suggest a command to whisper to that player. Shift-clicking a player's name will insert that name into chat. Shift-clicking a non-player entity's name will insert its UUID into chat.

Due to the extra tag, the above format may be recursively nested to produce very complex and functional text strings. However, a raw json text doesn't have to be complicated at all: virtually all properties are optional and may be left out.

To be valid, each object must have at least either text, translate, score or selector (everything else is optional). As a matter of shorthand, however, the entire Object may be substituted with a String. In this case, that string will be considered the value of the text property. For example,  is equivalent to. This shorthand substitution is valid anywhere a raw text object is required (including the base  argument of, the elements of the extra list, and the value of a "show_text" hover_event).

/tellraw also accepts an array of objects and/or strings; they are concatenated. It even accepts a tree of nested arrays; they are traversed depth-first. For example:

/tellraw @a ["Hello there, ",{selector:"@p"},"."] /tellraw @a [["The "],[["quick ","brown "],[{selector:"@p"}," jumps "],"over "],"the "],["lazy ","dog."]

Finally, unlike other commands using JSON, Strings support Unicode via the notation , where #### is the Unicode hexadecimal number for the desired character.

 * — give items to player
 * — can destroy item entities
 * — can replace items in block or entity inventories

clone
Clones blocks from one region to another.


 * Syntax




 * Color added to make reading easier. The in-game help for the clone command does not list the final argument — TileName is a placeholder name for the purpose of discussion.


 * Arguments


 * x1 y1 z1 and x2 y2 z2
 * Specifies the coordinates of two opposing corner blocks of the source region. May use tilde notation to specify distances relative to the command's execution.


 * The blocks that make up the corners extend in the positive direction from the coordinates used to identify them. Because of this, the lesser coordinates of each axis will be right on the region boundary, but the greater coordinates will be one block from the boundary, and the block volume of the source region will be (xgreater - xlesser + 1) × (ygreater - ylesser + 1) × (zgreater - zlesser + 1). For example,  has a 1-block volume, and   and   both identify the same region with an 8-block volume.


 * x y z
 * Specifies the lower northwest corner (i.e., the smallest coordinates of each axis) of the destination region. May use tilde notation to specify a distance relative to the command's execution.


 * maskMode (optional)
 * Specifies whether to filter the blocks being cloned. Must be one of the following:
 * — Clone only blocks with the block id specified by TileName.
 * — Copy only non-air blocks. Blocks in the destination region that would otherwise be overwritten by air are left unmodified.
 * — Copy all blocks, overwriting all blocks of the destination region with the blocks from the source region.
 * If left unspecified, defaults to.


 * cloneMode (optional)
 * Specifies how to treat the source region. Must be one of the following:
 * — Force the clone even if the source and destination regions overlap.
 * — Clone the source region to the destination region, then replace the source region with air. When used in filtered mask mode, only the cloned blocks will be replaced with air.
 * — Don't move or force.
 * If left unspecified, defaults to.


 * TileName (optional)
 * Specifies the block id (e.g., ) to copy when maskMode is set to  . Not optional when using   mode.


 * Result


 * Fails if the arguments are not specified correctly, if the block volume of the source region is greater than 32768 (enough for the equivalent of eight chunk sections), if the source and destination region overlap (unless using force clone mode), or if one or both regions isn't currently rendered.


 * On success, overwrites blocks in the destination region with blocks from the source region, leaving the source region unmodified (unless using move clone mode).


 * See also


 * — fill a region with a block

debug
Starts or stops a debugging session.


 * Syntax




 * Arguments


 * Starts a new debug profiling session.
 * Starts a new debug profiling session.


 * Stops the active debug profiling session.
 * Stops the active debug profiling session.


 * Result


 * Fails if trying to start a debug session when one is already active, or if trying to stop a debug session when none is running.


 * On success, starts or stops the debug session. While active, includes notifications about potential performance bottlenecks in the console. When stopped, creates a profiler results file in the folder "debug".

defaultgamemode
Sets the default game mode (creative, survival, etc.) for new players entering a multiplayer server.


 * Syntax




 * Arguments


 * mode


 * Specifies the default game mode for new players. Must be one of the following:
 * (can be abbreviated as  or  ) for survival mode
 * (can be abbreviated as  or  ) for creative mode
 * (can be abbreviated as  or  ) for adventure mode
 * (can be abbreviated as  or  ) for spectator mode


 * Result


 * Fails if the arguments are not specified correctly.


 * If successful, sets the default game mode that is shown on the world selection menu. New players that join the world will be put into the default game mode.


 * Examples


 * To set the default game mode to survival:,  , or


 * See also


 * – changes a player's game mode

deop
Revoke operator status from a player.


 * Syntax




 * Arguments


 * player
 * Specifies a player to remove from the list of operators. May be either a player name or a target selector, but target selectors will not evaluate; only actual player names will produce a useful result.


 * Result


 * Always succeeds if restrictions are satisfied. If player matches a name on the list of operators, the name is removed from the list and any player by that name no longer has operator status.


 * Examples


 * To remove Alice from the list of operators:

difficulty
Sets the difficulty level (peaceful, easy, etc.).


 * Syntax




 * Arguments

effect
The effect command manages status effects on players and other entities.


 * Syntax


 * (removes all effects)
 * (gives an effect)


 * Arguments


 * player
 * Specifies the target(s). Must be a player name or a target selector ( is permitted to target entities other than players).


 * effect
 * Specifies the effect to grant. Must be a status effect id (for example,  or  ).


 * seconds (optional)
 * Specifies the effect's duration in seconds. Must be between 0 and 1,000,000 (inclusive). If not specified, defaults to 30 seconds.


 * amplifier (optional)
 * Specifies the number of additional levels to add to the effect. Must be between 0 and 255 (inclusive). If not specified, defaults to 0. Note that the first tier of a status effect (e.g. Regeneration I) is 0, so the second tier, for example Regeneration II, would be specified by an amplifier level of 1.


 * hideParticles (optional)
 * Specifies whether the particles of the status effect should be hidden. Must be either  or  . If not specified, defaults to.


 * Result


 * Fails if arguments are not specified correctly, if player fails to resolve to one or more valid entities (named players must be online), if seconds was specified as 0 and the target did not have the effect, or if no effects were removed in  mode.


 * On success:


 * — clears all status effects from the target(s).


 * effect — Adds the status effect to the target(s). If a target already has the status effect, a new status effect with the same amplifier will only override the old duration if it is longer, but a new status effect with a higher duration will override any previous duration. If seconds is set to 0, cancels the specified effect instead.


 * Examples


 * To grant a Speed 1 effect to the nearest player for 60 seconds:


 * To grant a Speed 3 effect to the nearest player for 60 seconds:

 * On success, adds the specified enchantment to the item held by the target.


 * Examples


 * To give the Infinity enchantment to all players holding a bow:


 * Note


 * Although  enforces maximum levels and compatibility, other commands (such as, , and ) can bypass these restrictions.

entitydata

 * Syntax




 * Arguments


 * entity
 * Specifies the entity(ies) to be modified. Must be an entity UUID or the  target selector.

Color added to make reading easier.


 * Arguments


 * ''entity
 * Specifies the target to be the command's executor. Must be a player name or target selector. If more than one entity is selected, the command will be run once as each of them.


 * x y z
 * Specifies the position from which to run the command. x and z must be within the range -30,000,000 to 30,000,000 (inclusive). Coordinates specified with tilde notation are relative to the target, not to the position of the command's execution.


 * command
 * Specifies the command to be run. Must be a valid command.


 * x2 y2 z2 ( mode only)
 * Specifies the position of the block to check. x2 and z2 must be within the range -30,000,000 to 30,000,000 (inclusive). May use tilde notation to specify distances relative to (x,y,z).


 * block and data ( mode only)
 * Specifies the block id and data which the block at (x2,y2,z2) must match for the command to run. block must be a valid block id (for example, ), and data must be a valid block data for that type of block or   to match any block data.


 * Result


 * Fails if arguments are not specified correctly, if entity fails to resolve to one or more valid entities (named players must be online), if the checked block is not of the correct block id and data, or if the specified command fails.


 * On success, executes the specified command as if executed by the specified target(s) with operator-level permission at the specified coordinate.


 * Examples


 * To summon lightning bolts at the positions of every zombie:


 * To summon lightning bolts at the positions of every zombie standing on any type of sand:


 * To summon 10 creepers at the nearest player's position (only works as long as there are at least 10 entities in the loaded world):


 * See also

fill
Fills all or parts of a region with a specific block.


 * Syntax




 * The fill command also has an optional alternate syntax when using the  option:



Color added to make reading easier.


 * Arguments


 * x1 y1 z1 and x2 y2 z2
 * Specifies any two opposing corner blocks of the region to be filled (the "fill region"). May use tilde notation to specify distances relative to the command's execution.


 * The blocks that make up the corners extend in the positive direction from the coordinates used to identify them. Because of this, the lesser coordinates of each axis will be right on the region boundary, but the greater coordinates will be one block from the boundary, and the block volume of the source region will be (xgreater - xlesser + 1) × (ygreater - ylesser + 1) × (zgreater - zlesser + 1). For example,  has a 1-block volume, and   and   both identify the same region with an 8-block volume.


 * TileName
 * Specifies the block to fill the region with. Must be a block id (for example, ).


 * dataValue (optional)
 * Specifies the block data to use for the fill block. Must be between 0 and 15 (inclusive).


 * oldBlockHandling (optional)
 * Must be one of:
 * - Replaces all blocks (including air) in the fill region with the specified block, dropping the existing blocks (including those that are unchanged) and block contents as entities as if they had been mined with an unenchanted diamond shovel or pickaxe. (Blocks that can only be mined with shears, such as vines, will not drop; neither will liquids.)
 * - Replaces only blocks on the outer edge of the fill region with the specified block. Inner blocks are changed to air, dropping their contents as entities but not themselves.
 * - Replaces only air blocks in the fill region with the specified block.
 * - Replaces only blocks on the outer edge of the fill region with the specified block. Inner blocks are not affected.
 * - Replaces all blocks (including air) in the fill region with the specified block, without dropping blocks or block contents as entities. Optionally, instead of specifying a data tag for the replacing block, block id and data values may be specified to limit which blocks are replaced (see replaceTileName and replaceDataValue below)
 * If not specified, defaults to.


 * dataTag (optional)
 * Specifies the data tag to use for the fill block (for example, contents of a chest, patterns on a banner, etc.). Must be a compound NBT tag (for example, ). Cannot be combined with the replaceTileName and replaceDataValue arguments.


 * replaceTileName replaceDataValue (optional)
 * Arguments are only valid when oldBlockHandling is . Cannot be combined with the dataTag argument.
 * Specifies the block id and data of the blocks in the fill region to be replaced. If replaceDataValue is not specified, data value is ignored when determining which blocks to replace. If both arguments are not specified, replaces all blocks in the fill region.


 * Result


 * Fails if the arguments are not specified correctly, if the fill region is not rendered, if the block volume of the fill region is greater than 32768, if dataValue or dataTag are invalid for the specified block id, or if no blocks were changed.


 * On success, changes blocks in the fill region to the specified block.


 * Examples


 * Replaces all the orange stained hardened clay in the selected area with gold blocks.
 * Replaces with water the blocks in a 7x7x3 cube directly beneath the player.
 * Creates a house-sized box around the player and replaces with air any blocks that would have been inside the box.

 * "hardcore" is not a valid option for the mode argument, as it is technically not a game mode.


 * player (optional)


 * If specified, must be either a player's username or a target selector. If unspecified, defaults to the player using the command. When used in a command block, player is not optional.


 * Result

 * Specifies the page number of the command list or the command to provide help for. If not specified, defaults to  (the first page of the command list).


 * Result


 * Fails if page is not a valid page number, or if command name is not a valid command name. Technically fails even if a valid command name is specified, although it displays the usage of the command.


 * On success, displays a page of the command list. Multiplayer commands will not be displayed while in singleplayer, even when open to LAN players.


 * If a valid command name was specified, displays the usage for that command. For some complicated commands may show only the basic usage — additional information can sometimes be gained by attempting to type the command and using the auto-complete control (defaults to key) to explore available options for each argument.


 * Examples

 * Syntax




 * Result


 * Fails if any target selectors do not resolve to at least one online player, or if any named players are not online.


 * On success, sends a narrative message to the other players in the form of "* Your Name action" (e.g., "* Alice sneezes." or "* Alice exploded." ). If a multi-person target selector (e.g., @a) is used in action, the list of names is formatted as "name1 and name2" for two players, or "name1, name2, ... and nameN" for N players.

 * xd yd zd
 * Specifies the size of the area to spawn particles in.


 * Exception: When name is,  , or   and count is 0 or not specified, and speed is not 0, specifies the color of the particle in RGB format offset from the particle's default color ( 's default is a near-red (a random red tint between 0.8 and 1.0), while the others default to black). For example, with  ,   produces a red particle,   produces a green particle (red is reduced to 0 and green increased to 1),   produces a purple particle (blue is added to the original red), etc. With   or  ,   produces a black particle,   produces a green particle,   produces a dark blue particle, etc. If count is greater than 0, colors are randomized.


 * speed
 * Specifies the speed of the particle. Must be at least 0.

playsound
Plays a sound.


 * Syntax




 * Arguments


 * sound
 * Specifies the sound to play. Must be a sound event defined in sounds.json (for example, ).


 * A sound event may be affiliated with multiple sounds, and the sound which is actually produced will be chosen at random from them, modified by their "weight", just as the game normally would. For example, the  sound event will play one of several pig sounds at random, because the event has multiple sounds associated with it.


 * Resource packs may add their own events to sounds.json; the command will successfully play these. File names are not used by this command; it strictly uses the events defined in sounds.json (which may not even be similar to the original file names and paths), and thus a resource pack adding new sound files must define events for them (this is not necessary when replacing old sounds which are already in defined events).


 * source
 * Specifies which category in the music & sound options the sound falls under. Must be,  ,  ,  ,  ,  ,  ,  ,  , or.


 * player
 * Specifies the sound's target. Must be a player name or a target selector.


 * x y z (optional)
 * Specifies the position to play the sounds from. May use tilde notation to specify a position relative to the target(s).


 * volume (optional)
 * Specifies the distance that the sound can be heard. Must be at least 0.0. For values less than 1.0, the sound will be quieter and have a smaller sphere within which it may be heard. For values greater than 1.0, the sound will not actually grow louder, but its audible range (a 16-block radius at 1.0) will be multiplied by volume. There will always be a gradual falloff to silence based on distance from the center of the sphere.


 * pitch (optional)
 * Specifies the pitch of the sound. Must be between 0.0 and 2.0 (inclusive), and values less than 0.5 are equivalent to 0.5. Values lower than 1.0 lower the pitch and increase the duration; values greater than 1.0 raise the pitch and reduce the duration. The pitch value is a multiplier applied to the frequency, so if a value between 0.5 and 1.0 (inclusive) is doubled, the pitch will be an octave higher. (If you're a musician wishing to convert other intervals to pitch values, see Note block, but be aware that 1.0 won't be F♯ for all sound effects.) If not specified, defaults to 1.0.


 * minimumVolume (optional)
 * Specifies the volume for targets outside the sound's normal audible sphere. If a target is outside the normal sphere, the sound will instead be centered some short distance from the target (less than four blocks away), and  will determine its volume. Must be between 0.0 and 1.0 (inclusive).


 * Result


 * Fails if the arguments are not specified correctly, if player fails to resolve to one or more online players, or if the targets are unable to hear the sound from where it is played.


 * On success, plays a sound for the targeted players.

 * Specifies the position of the block to be modified. May use tilde notation to specify a position relative to the command's execution.


 * selector ( mode only)
 * Specifies one or more entities to modify. Must be a player name or target selector.


 * slot
 * Specifies the inventory slot to be modified. Valid values depend on whether a block or an entity is being modified.


 * For blocks, must be  where slot_number is replaced with a number specifying the slot.
 * Chests, dispensers, droppers, hoppers, and trapped chests are numbered 0 for the top-left slot and then increase first horizontally, then vertically (so, for example, a chest's top row slots are numbered 0 to 8 from left to right). Double chests and double trapped chests are treated as two single container blocks.
 * A brewing stand's bottom slots are numbered 0 to 2 from left to right, and its top slot is 3.
 * A furnace's slots are numbered 0 for the input slot, 1 for the fuel slot, and 2 for the output slot.
 * Other blocks which hold items but don't have inventory GUIs (flower pots and jukeboxes) can only be changed with.


 * For entities, must be one of the following, where slot_number is replaced with a number specifying the slot:

stats
Manages the updating of scoreboard objectives with the results of other commands.

Commands can be executed by blocks (specifically, command blocks and signs) or by entities (players can execute commands directly, and other entities can be the origin of commands indirectly with the command). When a command is executed, the command returns one or more "command stats": the success count, number of blocks affected, number of entities affected, number of items affected, and/or a query result (such as from ).

The stats command allows "selectors" and "objectives" to be set (or cleared) for each of these command stats for specific blocks or entities. Selectors (for example, ) are stored exactly as entered, and don't get evaluated immediately. When a command is later run by the block or entity, the stored selector is then used to target (other) entities and update their scoreboard objective with the value of the command stat. That value can then be displayed or operated on, just like any other scoreboard value.

The success count from a command block can also be acquired with a redstone comparator, but that is capped at a maximum value of 15, while scoreboard objectives can hold any value from -2,147,483,648 to 2,147,483,647. Success counts and query results are also usually displayed in the chat.

 * — returns the result of a command query
 * — returns a command's success count


 * selector ( mode only)
 * Specifies the selector to be evaluated when a command is run by the specified block or entity to determine which entity(ies) scoreboard objective is to be updated with the result returned by stat. May be anything because it won't be evaluated until a command is run by the specified block or entity, but only a player name or a target selector will produce useful results (though player names can be fake, so even real players don't need to be online).


 * objective ( mode only)
 * Specifies the name of the objective to be updated with the result returned by stat. May be anything because it won't be evaluated until a command is run by the specified block or entity, but only the name of a defined objective will produce useful results.


 * Result


 * Fails if the arguments are not specified correctly, if the specified block cannot track stats (in other words, it fails if the specified block is not a command block or sign), or if selector2 fails to evaluate to one or more valid entities (named players must be online).


 * On success, clears or sets the selector and objective to be updated with the result returned by stat.


 * Examples


 * To set the block at (0,64,0) to update scoreboard objective MyObj of the nearest player with the value of any query result returned by the block:


 * To stop the block at (0,64,0) from updating any scoreboard obectives with the success count of commands it executes:


 * To have the nearest wither skull update the scoreboard objective NumBlocks of fake player #FakePlayer with the number of blocks affected by commands executed by the wither skull:
