Minecraft snapshot 15w34d

Update: Snapshot 15w34d has been released to fix a memory allocation crash with the previous snapshot. Blame grum.

Update: Snapshot 15w34c has been released with even more changes to the melee combat mechanics, and some further (experimental) optimisations. Another reminder, nothing is final, we aren’t finished yet, and we are taking all feedback into account whilst designing the new gameplay. Take a backup before trying this snapshot, as it may break your world (in which case, you may yell at grum).

Update: Snapshot 15w34b has been released with further changes to the melee combat mechanics. Once again, please remember that the changes are absolutely not final nor balanced not even a little bit.

Zoooom!

That’s the sound of this update being pushed out really fast, due to some new speedy optimisations and speedy combat mechanics.

Todays snapshot makes a start on the melee combat changes, which are completely not final nor balanced at all in the absolute slightest not even a little bit really honestly seriously. We welcome all feedback, but please remember that nothing is yet balanced and the mechanics themselves are subject to change and redesign.

Here are some of the notable changes:

  • New “attack strength” combat mechanic.
  • Maps now start at a more useful zoom level.
  • New recipe for zooming in a map.
  • Lots of optimisations!
  • Improved command blocks.
  • Worsened Zombies’ arms getting tired.

And these are some of the fixed bugs:

  • [Bug MC-83471] - “CustomPotionEffects” Inoperable with Splash / lingering Potions
  • [Bug MC-85115] - Dragon Fireball doesn’t have a name (entity.DragonFireball.name)
  • [Bug MC-85592] - Default log4j2.xml is suboptimal
  • [Bug MC-86137] - Crash when breaking heads
  • [Bug MC-86138] - Pick block on Mob (Dragon) Head / Structure block crashes the game
  • [Bug MC-86152] - Records lose their custom name when placed in a record player
