Gameplay

 * Target selectors
 * Targets entities
 * Can specify type of entity by entity ID to either include or exclude with  or
 * Example: - kills all chickens within a radius of 50 blocks
 * Example: - any entity within a radius of 5 blocks will be teleported five blocks in the air
 * Commands
 * Modifies NBT data at a specific coordinate. The ,   or
 * will copy every block (the default behavior)
 * will only copy non-air blocks
 * will only remove unnecessary blocks
 * It can additionally be ,   or
 * will move the selection from the first location to the second location, which may overlap
 * will force the cloning operation, even if the areas overlap
 * only needs to be specified if using
 * Usage:
 * Example:
 * Allows commands to be run from the position of specified entities
 * A  argument allows the  command to run only if a block is detected at a specific location relative to the target
 * Usage:
 * {{cmd|execute    detect     to only fill the outer layer of blocks and fill the inner part with air, and   to fill the outer layer of blocks and ignore the inner part
 * Works similarly to {{cmd|setblock}}
 * Usage: {{cmd|fill        [dataValue] [oldBlockHandling] [dataTag]}}
 * Example: {{cmd|fill 1001 3 1002 1011 5 992 wool 6 replace}} will fill the given area with pink wool
 * Can filter certain blocks
 * Only if it’s used to fill in replace mode with “normal” blocks.
 * It does not work when filling with block entities.
 * Usage: {{cmd|fill [x] [y] [z] [x] [y] [z] [BlockName] [Data] replace [filterBlockName] [filterData]}}
 * {{cmd|particle}}
 * Spawns particles in a given area
 * It can also be relative to entities
 * Usage: {{cmd|particle    <xd> <yd> <zd> [count] [force] [player:entity]}}
 * Example: {{cmd|1=particle lava ~ ~1 ~ 1 1 1 0.5 50 normal @e[type=Chicken]}} will create 50 lava popping particles, centred one block above the block/entity running the command, spreading around a radius of 1 block, with a speed of 0.5, relative to all chickens in that world
 * The  argument can be set to   to display particles even if a player has his 'Particles' toggle set to Minimal or Decreased
 * List of particles:,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,
 * {{cmd|replaceitem|<entity&#124;block> ...}}
 * Can replace items in any inventory, including the inventories of mobs such as zombies
 * Usage:
 * {{cmd|replaceitem entity  [amount] [data value]}}
 * {{cmd|replaceitem block <x> <y> <z> [amount] [data value]}}
 * Example:
 * {{cmd|1=replaceitem entity @e[type=Zombie] slot.weapon minecraft:iron_sword 1 0}} will give all the zombies iron swords
 * {{cmd|replaceitem entity @p slot.hotbar.0 minecraft:fish 4 2}} will put 4 clownfish in the players first hotbar slot
 * {{cmd|replaceitem block ~ ~1 ~ slot.container.5 minecraft:redstone_block 1 0}} will put a redstone block in the 6th slot of a container 1 block above the player
 * {{cmd|stats <entity&#124;block> ...}}
 * Usage:
 * {{cmd|stats entity }}
 * {{cmd|stats block [x] [y] [z] }}
 * Alternative and more featureful way of interacting with
 * Will update a scoreboard objective based on the number of entities/blocks which have been affected by the command, it updates the objective for the entity that ran the command, fake players can be used when run in a command block
 * After the  there are currently 5 possible stats that can be updated: ,  ,  ,   and
 * For example: {{cmd|stats entity @a set AffectedBlocks @a Test}} will update a scoreboard objective named 'Test' for all players whenever a command is performed relative to them, the objective will update by the number of blocks affected by the command since the stat was set to, this means if the command is {{cmd|fill}} then it will update the objective for whoever is running the command (@a) by the number of blocks filled
 * {{cmd|testforblocks}}
 * Compares two areas of a world
 * The mode can be set to  or ,   is the default while   will ignore air
 * Usage: {{cmd|testforblocks <x1> <y1> <z1> <x2> <y2> <z2> [mode]}}
 * Example: {{cmd|testforblocks 100 64 100 107 69 107 0 64 0 masked}}

 * Clear titles immediately
 * {{cmd|title @a reset}}
 * Reset all title parameters to defaults (fade times)
 * {{cmd|trigger}}
 * Functions the same way as {{cmd|scoreboard players set}} or {{cmd|scoreboard players add}}, but can only modify objectives with the  criteria (referred to as "triggers") and can only modify the score of the player running the command
 * Can be used by non-operator players
 * For a player to run this command, the trigger must be enabled for that player
 * {{cmd|scoreboard players enable }} will enable the specified player to use the specified trigger objective
 * Trigger availability is stored per player, per trigger
 * One trigger may be disabled for a player, but that player can use a different trigger
 * One player may be unable to use a trigger, but another player can use the same trigger
 * Disabled after the trigger has been used (must be re-enabled to use the trigger again)
 * Mostly for use with {{cmd|tellraw}}
 * Usage: {{cmd|trigger <add:set> }}
 * {{cmd|worldborder}}
 * {{cmd|worldborder <set,add,center,damage,warning,get>}}
 * {{cmd|worldborder set <sizeInBlocks> <timeInSeconds>}}
 * Used to set size of border. The first argument sets the size of the border and the second sets the speed of the border to expand or shrink
 * {{cmd|worldborder add <sizeInBlocks> <timeInSeconds>}}
 * Adds blocks to the current size of the world border. Can use negative (-) numbers to subtract the size of the border
 * {{cmd|worldborder center <x> <z>}}
 * Sets the center of where the border will be placed.
 * {{cmd|worldborder damage <buffer|amount>}}
 * Allows you to customise the amount of damage taken while outside the border, and buffer, the higher value, the further you can be outside the border without taking damage
 * {{cmd|worldborder warning <time|distance>}}
 * Allows you to customise how far you have to be or the time for how long it takes to activate the world border warning
 * {{cmd|worldborder get}}
 * Tells the player running the command the current width of the world border
 * NBT Tags
 * Mostly for use in adventure mode
 * Items with this tag display the names of the blocks that they can destroy in the item tooltip
 * Example: {{cmd|give @p minecraft:diamond_shovel 1 0 {CanDestroy:["minecraft:sand","minecraft:grass"]} }} to give a diamond shovel that can break grass and sand
 * Putting an invalid item name in will display as "missingno" under the "Can Break" list.
 * Allows placing of certain blocks against other blocks in adventure mode
 * Example: {{cmd|give @p minecraft:stone 16 0 {CanPlaceOn:["minecraft:diamond_block"]} }}
 * Putting an invalid item name in will display as "missingno" under the "Can be placed on" list.
 * Allows a command block or sign to increase a certain score in the scoreboard when it runs successfully
 * The command will increase the score based on the number of items/blocks/entities/successes
 * For example, a command block with this tag running a command which affects items (e.g. ) will cause it to update the score based on the number of items given
 * Usage:
 * Allows hiding of certain parts of the tooltip
 * Bit field determining which parts of the tooltip to hide on an item. 1 for, 2 for  , 4 for  , 8 for  , 16 for  , and 32 for various other information (including potion effects,  , written book   and  ,  , and  ).
 * Examples: Setting bit field to 3 would hide both  and   tags, and setting to 63 would hide everything.
 * The number of ticks before an item entity can be picked up.
 * Set to 32767 for items that can't be picked up
 * Option to show or hide all particles for a potion effect, while the 'Ambient' tag only shows fewer particles. Set to 1 to show, 0 to hide.
 * A way to lock containers from being opened using NBT tags
 * Mostly useful for adventure maps in adventure mode
 * Containers can be unlocked by clearing their string for Lock
 * Locked containers can only be opened while holding anything renamed to the given string, item is not removed on use
 * The lock can be completely removed utilizing the command
 * BlockItem instances can now hold a custom NBT tag that is merged into a block entity when it’s placed
 * Example: {{cmd|give @p command_block 1 0 {BlockEntityTag:{Command:"{{cmd|setblock ~ ~ ~ minecraft:diamond_block}}" }} }}
 * Controls villagers giving xp for trading, set to true or false
 * Defines whether a written book is an "Original" a "Copy of Original" or a "Copy of a copy"
 * Determines whether sound is produced by an entity, such as idle and hurt sounds. Setting to 1 disables sound
 * Disables an entity's AI
 * Entities without AI do not attack players or move or rotate on their own, and do not despawn, they also do not respond to gravity or collision with other mobs, but can still take damage, die, and ride other entities
 * Gamerules
 * Prevents command block output from being stored in chat logs. In multiplayer, also prevents player-initiated commands from being stored. Unrelated to commandBlockOutput, which is output into the visible chat
 * Controls how often a random tick occurs; random ticks influence how fast plants and crops grow, how fast pigmen spawn from portals, how fast farmland updates, how fast grass and mycelium grow and decay, etc...
 * If set to 0, random ticks never occur
 * Gamerule to enable/disable reduced information on the F3 debug screen
 * Op-only unlike the 'reduced debug info' toggle in multiplayer settings
 * Overrides 'reduced debug info' settings in clients
 * If set to false, player-run commands will not show a success message
 * Prevents death messages like "[player] fell out the world" from appearing in the chat
 * The ability to create gamerule variables
 * These are fake gamerules which don't actually affect your world, but can be used with {{cmd|stats}} with the new  argument to update a scoreboard objective based on the value of that gamerule
 * Declare using {{cmd|gamerule <newRuleName> }}
 * Access using {{cmd|gamerule <newRuleName>}}
 * Statistics
 * Detects how many cm the player has moved while crouching
 * Detects how many cm the player has moved while sprinting
 * Detects how much time has passed (in ticks) since the player's last death
 * Detects how many times the player has talked to villagers
 * Detects how many times the player has traded with villagers
 * Scoreboards
 * New objective criteria for team-specific kills, e.g.:
 * New objective criteria '
 * Acts like the  criteria
 * Mostly for use with {{cmd|tellraw}}
 * The ability to iterate over every scoreboard player with
 * This will also affect people who have not yet joined the world
 * Fake players with a name starting with # will never show up on the sidebar
 * New {{cmd|scoreboard}} subcommands: {{cmd|scoreboard reset}}, {{cmd|scoreboard operation}}, {{cmd|scoreboard test}} and {{cmd|scoreboard enable}}
 * The  subcommand can reset all objectives for a player or reset a player's objectives one by one
 * Example: {{cmd|scoreboard players reset @a anObjective}} will reset the scores of an objective named anObjective for all players in the world
 * The  subcommand can apply arithmetic operation to scores (+ – * / % < > =) and accumulate player scores
 * Example: {{cmd|1=scoreboard players operation #teamscores redScore += @a[team=red] blueKills}} adds every red player's count of kills on blue to the red team's score of kills
 * Can be tested with a comparator to see if two scores are greater than, smaller than or equal to each other
 * The  subcommand can be used to test if a scoreboard value is between a min and a max value
 * Example: {{cmd|scoreboard players test #global anObjective 12 19}} checks whether the global score of the given objective is between 12 and 19, inclusive
 * The  subcommand can be used to enable a   objective
 * Example: {{cmd|scoreboard players enable aTrigger}} enables a  named aTrigger
 * Different teams can now have different objectives displayed in the sidebar
 * Example: {{cmd|scoreboard|objectives setdisplay sidebar.team.yellow anotherObjective}} (referring to team color, not team name)
 * Testing for scores now also works in  entity selector
 * Added scoreboard team property to disable name tag visibility: {{cmd|scoreboard teams option nametagVisibility}} with options,  ,   and   (default)
 * Added scoreboard team property to disable death messages: {{cmd|scoreboard|teams option deathMessageVisibility}} with options,  ,   and   (default)
