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. 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 poitive or negative direction for that axis. A single tilde by itself is shorthand for.

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

Usually you can mix absolute coordinates with relative coordinates. For example,  will keep your "x" and "z" coordinates the same, but teleport you to absolute height 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, you might write:

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


 * Target the nearest player.
 * Target the nearest player.


 * Target a random player.
 * Target a random player.


 * Target all players.
 * Target all players.

Target selector variables can be used by themselves, or can be further modified with target selector arguments.

The following target selector variable has appeared in but has not yet been released in a full version:


 * Target all entities (including players).
 * Target all entities (including players).

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 arguments 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.


 * Selecting targets by coordinate




 * Selects only targets at that exact position (ignoring fractions). Use tilde notation to specify a coordinate relative to the command's execution position.


 * Selecting targets by radius




 * Selects only targets within specified radius/i from the position where the command was executed.  specifies the maximum radius that targets can be from the coordinate, and   specifies the minimum radius. It is possible to use either without the other (  to specify targets within a certain radius, and   to specify targets further than a certain radius).


 * If coordinate and radius/i are both defined, the radius 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.


 * 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 game mode




 * Selects only targets with the specified game mode. Permitted value for M are:


 * : all game modes
 * : survival mode
 * : creative mode
 * : adventure mode


 * In the, M may also be  for spectator mode.


 * Selecting targets by count




 * Selects only the specified number of targets. 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 a negative value, the order of targets is reversed (for example,   will return the three farthest targets). When used without position selection, targets are returned in the order of creation (for example,   will select the first target created and   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.


 * Selecting targets by team




 * Selects only targets on team TEAM.




 * Selects only targets not on team TEAM.


 * Selecting targets by name




 * Selects only targets named NAME.




 * Selects only targets not named NAME.

The following target selector arguments have appeared in but have not yet been released in a full version:


 * 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 positive "x" direction (i.e., south), DY blocks in the positive "y" direction (i.e., upwards), and DZ blocks in the positive "z" direction (i.e., east). All values must be positive. 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


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




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




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


 * Selecting targets by horizontal rotation


 * 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).




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




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


 * Selecting targets by type


 * Primarily only used with the  variable (because all players are  ). "Entity types" are the entity IDs used to identify different types of entities internally (see chunk format).




 * Selects only targets of the specific entity type.




 * Selects only targets not of the specific entity type.

Data tags
NBT tags can be specified for items and entities created with the, and other commands. Data tags are data structures. The format is JSON, although it is not strict (lenient). The data is represented as a comma separated list of pairs. Each pair has the format. The key is the name of the NBT tag and the value is the data that should be assigned to it. Tag names are case-sensitive, and whitespace outside keys or values is ignored.

The value can be different types:


 * String is a piece of text, can be wrapped with double-quotes. Double quotes have to be used if the String contains commas, curly braces or square brackets. To use double-quotes inside Strings, the quote is escaped by a backslash . When using most commands, escaping is disabled (except for double quotes) and keys must not be quoted (probably a bug ). This causes an issue where trailing backslashes do not work (as do any other things that need to be escaped), even when escaped properly. The reason is that it escapes the quotation mark after the string which causes a malformed JSON object.
 * Number are 1 or more digits that can have a leading sign ( / ). They're classified in Integers, that don't have a decimal mark, Doubles, that uses a dot as a decimal mark, and Floats, that also have   appended after the number. Examples:  ;  ; &
 * List (or 'Array') is multiple, comma separated values wrapped with square brackets. The containing values do not need to be of the same type.
 * Boolean can either be  or , but using Numbers works, too. When using numbers, 0 is false, everything else is true.
 * Compound or 'Object' is a container for data structures (as explained above). They are wrapped with curly braces.
 * Notice: The Data tag itself is a Compound. Example: 


 * null This is a placeholder an empty value. Do not put quotes.

When commands such as /testfor, /testforblock, and /clear are used to match NBT tags, they only check for the presence of the given 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/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.

For a complete listing of defined tags (though not all can be modified by commands), see:
 * Blocks
 * Entities
 * Mobs
 * Projectiles (arrows, fireballs, thrown potions, etc.)
 * Items (items on the ground)
 * Vehicles (boats, minecarts, etc.)
 * Dynamic Tiles (primed TNT, falling sand/gravel)
 * Other Entities (firework rockets, paintings, and item frames)
 * Tile Entities (chests, furnaces, command blocks, mob spawners, signs, etc.)
 * Player
 * Items (items in player's inventory or containers)

For a complete list of identifiers, see:
 * blocks
 * items
 * entities
 * enchantments
 * status/potion effects
 * attributes

Raw JSON Text
The command uses a specific lenient JSON format for raw chat messages. Similar to the NBT format notation above, concepts such as Strings, Objects (Compounds), and Lists are used to represent the various properties of raw chat.

For a direct tutorial to tellraw commands, see this thread. For a tool to easily create tellraw commands, see this. Note that both links are external to the Minecraft Wiki and may be outdated.

The format of "" 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.
 * : 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), "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), 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).
 * : The URL, chat, or command 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 compound for displaying 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 player'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.

Due to the extra tag, the above format may be recursively nested to produce very complex and functional text strings. However, a raw json string 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, or score (everything else is optional). As a matter of shorthand, however, the entire Object may be substituted for 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).

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

 * Success Conditions


 * A command's Success Conditions must be met in order for the game to consider the command "successful". This is used to determine a variety of things, such as the output of a redstone comparator feeding from command block with a command. Note that not all "successful" commands actually do something, and not all "failed" commands fail to do something useful.


 * Restrictions


 * Describes restrictions on who can use the command or in what context.


 * None: The command can be used by any player in any world. The following commands have no restrictions:, , , and.


 * Operator: The command may only be used by an operator or in singleplayer mode with cheats enabled. On multiplayer servers, the results of these commands are broadcast to other ops online.


 * Multiplayer: The command is only available on a multiplayer server. The following commands are restricted to multiplayer servers:, , , , , , , , , , , , , ,.
 * No multiplayer commands permit target selectors in arguments and, except for, multiplayer commands cannot be used in command blocks. Many of these commands can be used on players who have never been to the server, or even on names which are not (or cannot be) registered as Minecraft accounts.


 * No command blocks: The command cannot be executed by a command block.

 * Syntax




 * Arguments


 * address|name
 * Must be a player name or an IP address.


 * reason (optional)
 * Text to be displayed with the ban, to other operators and in the server logs.


 * Result


 * Fails if address|name is neither a valid IP address nor the name of an online player.

banlist
Displays banlist.


 * Syntax




 * Result


 * Always succeeds. Displays banned IP addresses or banned players.

blockdata

 * dataTag
 * The data tag elements to be added to, or overwrite elements of, the specified block.


 * Result


 * Fails if dataTag is not a valid data tag specification for the targeted block.


 * On success, modifies the data tag of the targeted block.


 * See also

 * Arguments


 * player (optional)
 * Must be a player name or a target selector. If not specified, defaults to the command's user. Not optional in command blocks.


 * item data (optional)
 * Specifies the id and data of the item to be cleared. If neither argument is specified, clears all items from the inventory. If item is specified, but not data, all items with id item are cleared, regardless of their data.


 * Result


 * Fails if the arguments are not specified properly, if player fails to resolve to one or more online players, or if no items are removed.


 * On success, removes the specified items from the player(s).


 * Examples


 * To clear your entire inventory:


 * To clear all items from Notch's inventory:


 * To clear all wool items from Notch's inventory:


 * To clear all orange wool items from the inventory of all players:


 * Future


 * Two additional arguments have appeared in development versions, but have not yet appeared in a full release:


 * maxCount (optional)
 * Specifies the maximum number of items to be cleared. If not specified, or if, clears all items. If  , does not clear items, but returns successfully if there were items that could have been cleared (allowing detection of items rather than clearing of items).


 * dataTag (optional)
 * Specifies the data tags of the item to be cleared (only items matching the specified data tags will be cleared — data tags not specified will not be considered).


 * In addition, data can be set to  to ignore data and clear all blocks of a certain id when maxCount or dataTag must be specified but data needs to be ignored.


 * For example, to clear all golden swords with the "Sharpness I" enchantment from the nearest player, regardless of their damage value:


 * See also


 * — give items to player

clone
Clones blocks from one region to another.


 * Syntax




 * The in-game help for the clone command does not yet list the final two arguments. mode2 and TileName are placeholder names for the purpose of discussion.


 * Arguments


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


 * mode (optional)
 * Must be one of:
 * — Clone only blocks with the specified block id (see TileName below).
 * — 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 not specified, defaults to.


 * mode2 (optional)
 * Must be one of:
 * — Force the clone even if the source and destination regions overlap.
 * — Clone the source region to the destination region, then replace the copied blocks with air. When used in filtered mode, only the cloned blocks will be replaced with air.
 * — Don't move or force. Used when TileName also needs to be specified.
 * If not specified, defaults to.


 * TileName (optional)
 * Specifies the block id (for example, ) to copy when using filtered mode. Not optional when using filtered 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 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 mode).


 * See also


 * — fill a region with a block

debug
Starts or stops a debugging session.


 * Syntax




 * Description


 * Starts a new debug profiling session or stops the session currently running. It notifies about potential performance bottlenecks in the console when active and creates a profiler results file in the folder debug when stopped.


 * Success Conditions


 * Can only stop if a session is running.

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


 * Syntax




 * Arguments


 * mode


 * Must be one of three values:
 * (can be abbreviated as  or  ) for survival mode
 * (can be abbreviated as  or  ) for creative mode
 * (can be abbreviated as  or  ) for adventure mode


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


 * Result


 * Fails if arguments aren't specified properly.


 * 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:


 * Future


 * An additional value for the mode argument has appeared in development versions, but has not yet appeared in a full release:
 * (can be abbreviated as  or  ) for spectator mode


 * See also


 * – changes a player's game mode

deop
Revoke op status from a player.


 * Syntax




 * Description


 * Revokes a player's operator status.


 * Success Conditions


 * Always succeeds.

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


 * Syntax




 * Arguments


 * new difficulty


 * Must be one of four values:
 * (can be abbreviated as  or  ) for peaceful difficulty
 * (can be abbreviated as  or  ) for easy difficulty
 * (can be abbreviated as  or  ) for normal difficulty
 * (can be abbreviated as  or  ) for hard difficulty


 * "hardcore" is not a valid option for the new difficulty argument, as it is not a difficulty.


 * Result


 * Fails if arguments aren't specified properly.


 * If successful, changes the game's difficulty. On a multiplayer server lasts only until the server is restarted — on restart, difficulty is reloaded from server.properties.


 * Examples


 * To change the difficulty to hard:


 * See also


 * – changes a player's game mode (creative, survival, etc.)

effect
These commands manage status effects on players.

effect
Adds or removes a status effect to or from players.


 * Syntax




 * Arguments


 * player
 * Specifies the target(s). Must be a player name or a target selector.


 * effect
 * Specifies the effect to grant. Must be a status effect id.


 * 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.


 * Result


 * Fails if arguments are not specified correctly, if player fails to resolve to one or more online players, or if seconds was specified as 0 and the target did not have the effect.


 * On success, adds the status effect to the target. If the 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:


 * To clear any Haste effects from all players:


 * Future


 * The upcoming  target selector allows effects to be given to any entity, not just players.


 * Effects may be specified by name id (for example, ).


 * An additional argument has been added:




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

 * Specifies the target(s). Must be a player name or a target selector.


 * Result


 * Fails if player does not resolve to one or more online players, or if no effects are removed.


 * On success, clears all effects from the specified players.

 * Result


 * Fails if arguments are not specified correctly, if player fails to resolve to one or more online players, or if the enchantment is not valid for the item or conflicts with other enchantments.


 * 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:

Executes a command with a different user and position, but only if a certain block is detected.


 * Syntax




 * Arguments


 * entity
 * Specifies the target to be the command's executor. Must be a player name or target selector.


 * 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). May use tilde notation to specify distances relative to the target.

 * 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).

 * - 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 valid data tag for the specified block id. Cannot be combined with the replaceTileName and replaceDataValue arguments.

 * - How often a random tick occurs (such as plant growth, leaf decay, etc.) per chunk section per game tick. Like other game rules, may be set to any value, but only numbers will be useful: 0 to disable random ticks, higher numbers for more random ticks (default value is 3).
 * - Whether the debug screen shows all or reduced infomation
 * - Whether the feedback from commands executed by a player should show up in chat
 * - Whether a message appears in chat when a player dies


 * In addition, new game rules may be defined and set (by providing a value) or queried (by not providing a value). For example,  defines a new game rule called   and sets its value to 10. Attempting to query a game rule which has not yet been set will cause the command to fail (a change from the previous behaviour of always succeeding).

 * 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).

 * 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).

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) — values lower than 1.0 lower the pitch and increase the duration, values greater than 1.0 raise the pitch and reduce the duration. 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 arguments are not specified properly, 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.
