Java Edition 14w03a

14w03a is the fourth snapshot for Java Edition 1.8, released on January 16, 2014,^[1] which adds the /clone and /fill commands as well as /gamerule logAdminCommands.

Additions

/clone

Clones all the blocks (not entities) from a given area to a different given area.
Up to 4096 blocks can be copied.
- - The clone can be masked or replace - replace copies every block, masked only copies non-air blocks.
- Usage: /clone <x1> <y1> <z1> <x2> <y2> <z2> <x> <y> <z> [mode].
- Example: /clone 1001 3 1002 1011 3 992 1001 5 992 masked.

/fill

Fills a given volume with a specified block.
Up to 4096 blocks can be filled.
- oldBlockHandling works like with /setblock, but with additional options: hollow to only fill the outer layer of blocks and fill the inner part with air, outline to fill the outer layer of blocks and ignore the inner part.
Works similarly to /setblock
- Usage: /fill <x1> <y1> <z1> <x2> <y2> <z2> <TileName> [dataValue] [oldBlockHandling] <dataTag>.
- Example: /fill 1001 3 1002 1011 5 992 wool 6 replace.

logAdminCommands
- If set to false, prevents all command blocks from outputting to the client console.
- If used on a server, it also does not log player executed commands in the server's log.
Players still see other players' executed commands in chat.

Now only drop iron ingots when killed by the player, either through combat or potions, or player-activated mechanisms such as manually lit TNT.
If killed without player intervention, only drops poppies.

When struck by lightning, now transform into witches, similar to pigs transforming to zombie pigmen and creepers to charged creepers.

Now only drop gold nuggets and rare drops when killed by the player, either through combat or potions, or player-activated mechanisms such as manually lit TNT.
If killed without player intervention, only drops rotten flesh.

/tp

Now supports rotation arguments.
- Example: /tp @p ~ ~ ~ ~20 ~40 teleports the player so that they face 20 degrees to the right and 40 degrees downwards.

Now supports cubic areas.
- Example: @e[x=0,y=0,z=0,dx=10,dy=10,dz=10] gets all entities between 0,0,0 and 10,10,10.
The radius value in selectors is now based on the block center.
- A radius of 0 works for exact block positions.

Item tooltips

Block IDs

NBT data in commands can now use block/item names in place of numerical IDs.
Old IDs still work, but are being phased out slowly.
Other occurrences of blocks/items now need to be named IDs.
Regular IDs in commands no longer work. /give [player] 1 is now /give [player] stone.

F3 hotkeys

Skin customization

Uses a char.png file with new layout and new dimensions.
- Dimensions for the file are now 64×64.
Right and left arms and legs are now editable independently.
The hat layer is now full-body, can be transparent.
- Overlays for arms, legs, head, and body are called sleeves, pants legs, hat, and jacket respectively.
Backward-compatible with older skins.
- Old skins still work, but do not have the new features.
- New skins when used in pre-14w02a versions act like old skins.
New "Skin Customization" button in the options menu.
- Cape visibility is now toggled from here.
- Players can toggle the visibility of overlays, independent for each limb/body part.
