14w26a is the twenty-ninth snapshot released for 1.8, released on June 25, 2014,^[1] which adds the debug mode world type and the /replaceitem command.

It was strongly advised to make a backup of a world before using this snapshot, because of block-corrupting problems that were not corrected until 14w26c.^[1] A potential means of recovering corrupted worlds using MCEdit is available.^[3]

This snapshot is the first after a decision to release snapshots on Wednesdays rather than on Thursdays.^[1]

Debug mode world type

• Useful for resource pack makers.
• Hold ⇧ Shift and cycle through "World Type" to select it.
• Spectator mode recommended to avoid crashes (Creative mode can also be used without any effect on some machines).
• All possible blocks with all possible data values are generated.
  • They are arranged in a grid across height Y=70, with a barrier floor at Y=60.
• Blocks placed are deleted, and blocks destroyed are restored.
  • There is a special generator option preventing this. It is called "debug_all_block_states". If the player changes this to "flat" or "default" in NBTexplorer, they are able to interact with the world. (Only for a short period though, on most machines there is a lot of lag or the game crashes - not recommended to play Survival on)

/scoreboard operation

• Added >< scoreboard operator.

/replaceitem <entity|block> ...

• Can replace items in any inventory, including the inventories of mobs such as zombies.
  • Full syntax:
    • /replaceitem entity <entity> <slot> <item> [amount] [data value].
    • /replaceitem block <x> <y> <z> <slot> <item> [amount] [data value].
  • Example: /replaceitem entity @e[type=Zombie] slot.weapon minecraft:iron_sword 1 0 gives all the zombies iron swords.
  • Example: /replaceitem entity @p slot.hotbar.0 minecraft:fish 4 2 puts 4 clownfish in the players first hotbar slot.
  • Example: /replaceitem block ~ ~-1 ~ slot.container.5 minecraft:redstone_block 1 0 puts a redstone block in the 6th slot of a container 1 block beneath the player.

Gamerules

• sendCommandFeedback
  • If set to false, player-run commands don't show a success message.

General

• Switched to only/mostly using blockstates in the code, though not all block combinations are blockstates yet.

Command blocks

• X/O button next to "Last output" in command block to turn off the last output string.

Furnace

• Empty furnaces now only accept fuel and empty buckets in the fuel slot.

Item frames

• The wood part of the frame now uses the oak texture rather than the birch texture.

Melon stems

• Changed model from to

Pumpkin stems

• Changed model from to

Customized world type

• Has an ocean monument toggle.

Swampland

• Re-added marsh-like areas which were removed in 13w38b after initially being introduced in 13w36a.^[4]

Witch huts

• No longer have a red mushroom inside the flower pot.^[5]

/execute

• Now has a detect argument (sub-command, only works when used with execute).
  • Allows the execute command to run only if a block is detected at a specific location relative to the target.
  • Example: /execute @a ~ ~ ~ detect ~ ~-1 ~ minecraft:grass 0 say You are standing on grass..

/fill

• Block limit changed from 4096 to 32768 blocks.

/worldborder

• • Now has an add argument.
    • Similar to the set argument, but can be used to add (or remove) a certain number of blocks to the world border distance.
    • Negative numbers can be used to remove blocks.
    • Example: /worldborder add -75 shrinks the world border width by 75 blocks.

Block models

• Instead of specifying uvs, the player can now choose textures to be projected onto the model.

Resources

• Reworked 3D resources, adding the possibility of new blocks with multiple textures.

• Items in first-person view no longer move up and down when switching between 2 identical items by changing the selected hotbar slot.
