Minecraft:Java Edition 1.9.1-pre1

1.9.1-pre1 is the first pre-release for Minecraft:Java Edition 1.9.1,<ref>https://web.archive.org/web/0/http://www.mojang.com/2016/03/minecraft-191-pre-release-1/</ref><ref>Template:Tweet</ref> released on March 9, 2016.

Additions

Items

Minecraft:Armor

• New armor attribute: generic.armorToughness.
  • Damage formula is now <math>totalDamage=damage\times(1-\frac{max(\frac{defensePoints}{5},defensePoints-\frac{damage}{2+\frac{toughness}{4}})}{25})</math>, i.e. increased toughness means less armor defense point reduction from strong attacks.
  • Diamond armor has toughness 2, all other armor has toughness 0. A full set of diamond armor, therefore gives a toughness attribute of 8.
• New option enableWeakAttacks in options.txt.
  • Defaults to false. When false, the client will ignore attempts to attack when weapon cooldown is less than 75% recharged.
  • The effect was removed in the final release, however the option itself remains.

Minecraft:Elytra

• Added sound effects, while gliding in the Elytra.
  • Sound event item.elytra.flying.
