Protocol version


13w05a is the seventh snapshot released for Java Edition 1.5.[1]



  • Fully implemented multiple snow heights.
  • Drops one snowball for every layer of snow.
  • Each level of snow has its own height collision.
    • The topmost layer of snow does not have collision, so the player is always slightly sunken in the snow.
    • Visually, four layers of snow is the same height as a slab. However, five layers of snow have the same collision height as a slab.
  • Crafting recipe is 3 snow blocks in a row to create 6 snow layers.
    • For each thin layer of snow crafted, the player loses exactly half the snowballs required to produce it.



  • Increased range.
  • Effects are infinite upwards with the beam.
    • 1 layer: 41 blocks diameter (previously 33).
    • 2 layers: 61 blocks (previously 49).
    • 3 layers: 81 blocks (previously 65).
    • 4 layers: 101 blocks (previously 81).
  • Now uses the 8s bit on block 149 to represent its powered state, rather than a separate block ID, 150.
    • Block 150 is deprecated.
  • Improved lighting.
  • No longer prevent sprinting.


  • Everything now randomly takes 2-3 uses to fully grow.

Command format[edit]

  • Added team mechanics including custom name colors, friendly fire options and objective tracking per team instead of per player.
  • Added a new display type – displays value below nametags.
  • Added a new criterion – health, ranging from 0 to 20.
