  • collisionRule added as a team rule to the scoreboard.
    • It determines whether or not entities can push each other, and whether or not it's team dependent.
    • Subcommands: always, never, pushOtherTeam, pushOwnTeam


  • Most entities can now be pushed by other entities.
    • The exceptions being: items, paintings, ender crystals, areaEffectCloud, item frames and xp orbs.
    • These can be overridden for mobs and players through a team rule.
    • The same class of entities are now "magnetic" to the fishing rod bobber, and in the case of mobs/players will no longer suffer from knockback or pseudo-damage.
  • Armor protection calculations have been nerfed:
    • Max (20) armor points damage reduction reduced from 80% to 66%. (Changed back again in 16w02a)
    • Armor points count for less as the attack strength increases: Each 2 (Heart.svg) done by the attack reduces the effective defense points by 1 (Half Armor.svg).
  • Sharpness and Protection enchantments have been nerfed.
    • Each sharpness level now adds 1 (Half Heart.svg) damage to the base damage at level I and an additional 0.5 (Heart.svg × 0.25) for each additional level, down from a flat 1.25 (Half Heart.svg) per level.
    • Protection enchantment bonuses are now linear instead of quadratic.
Command Blocks
  • Can no longer be placed by players who are unable to use commands.
All mobs
  • No longer reset their AI when hit.
  • Due to MC-87946, all hostile mobs can now draw line of sight through solid blocks in order to track the player.
Skeletons, creepers, and zombies
  • Detection range for players wearing their corresponding mob head adjusted to be 50% of the normal range again.
  • Optimized memory usage when connected to servers.[2]
