Additions

Mobs

Minecraft:Donkeys, Minecraft:horses and Minecraft:mules

• Added a UI to control saddle/inventory/armor.
• Can be accessed by sneaking and right-clicking, or by pressing the inventory button while riding.
• Some features of the UI are specific to certain mobs:
  • All three mobs have a saddle slot.
  • Only horses have an armor slot.
  • Donkeys and mules have an inventory of 15 slots when given a chest.

General

Minecraft:Attribute system

• Started to move over various things to a new attribute system:
  • Item attributes using NBT data:
    • Attributes can be additive, subtractive and multiplicative using a set value.
    • Some items have default modifiers in place of previously hard-coded attributes.
    • Examples of possible changes players could make: A bow that slows the holder, a helmet that buffs health, etc.
  • Entity attributes:
    • These properties can now be changed as easily as any other NBT attribute.
    • Entity speed, base health, base attack.
  • Other properties like weapon damage/bow draw speed/sword swing speed are yet to follow.

Internal chat system

• Lots of messages should be translated now that were not previously.
• Messages are now better modularized.
• Server messages can be sent by their code-defined name, allowing the client to utilize the correct translation according to their language settings.
• Color can be specifically designated, preventing leakage into further messages.

Changes

Items

Minecraft:Horse armor

• No longer stackable.

Minecraft:Tools

• Instead of replacing the barehanded damage (Template:Hp), pickaxes, shovels, axes and swords now add their damage onto the barehanded damage.

General

Minecraft:Resource packs

• Lots of work toward a new resource pack system, but not finished yet.
  • Currently still compatible with texture packs.
