Protocol version


13w03a is the fifth snapshot released for Java Edition 1.5,[1] which adds droppers, minecarts with hoppers, and the /testfor command.

13w03a was reuploaded twice. The first time was later on January 17, 2013, to fix an issue with droppers duplicating items,[2] and it was soon reuploaded for a second time half an hour later fixing the inability to break blocks by punching, and random crashes when breaking blocks and items.[3]



  • Places items in containers in front of them.
    • If there is no container it will eject the item without using it.
    • A dispenser "shoots" items at the player, while a dropper "throws" items at them.[2]
  • Crafted using cobblestone, a hopper, and a piece of redstone:
Ingredients Crafting recipe
Cobblestone +
Hopper +

Non-mob entities[edit]

Minecart with Hopper
  • Crafting recipe is a hopper on top of a minecart.
  • Can only be emptied by passing over a hopper.
  • Can pick up items it passes over.

Command format[edit]

  • Command to test for players.
  • Uses comparators to get an analog redstone signal indicating the amount of found players.



Pillar quartz blocks
  • Can now be placed in any orientation – placement works like with wooden logs.
Command blocks
  • Comparators fed by command blocks will now indicate whether the last run command was run successfully.
Detector rails
  • Comparators powered by them now give out a signal depending on the fullness of the container on the rail.
Locked Chests
  • Now have their crash fixed causing their texture to be changed again.
  • Creating an infinite water source no longer needs a block underneath, but has to have a water source block.
    • Players cannot ruin oceans/rivers with buckets.


  • Scales to difficulty.
  • They now shoot faster when their target is closer.
  • They shoot players one block away.
  • Made them harder to shoot.
  • Scales to difficulty.
  • They now group upon targets.
  • When on fire, they can now set players on fire.
  • Now become aggressive and come towards the player when shot from further away.

Non-mob entities[edit]

Minecart with TNT
  • When blown up using activator rails, they no longer destroy rails and supporting blocks.
  • Still blows up redstone materials.


  • Added some new chat options in multiplayer menu:
    • Focused Height
    • Unfocused Height
    • Width
  • Moved the texture packs button (no longer appears on the main menu).
    • Players can now change texture packs in-game.
