Additions

• Slime Block
  • Crafted with 9 Slimeballs, can also be crafted back into 9 Slimeballs
  • Players, mobs and particles that land on their top side will bounce, as if on a trampoline
    • Bounce rebound velocity is scaled by impact velocity
    • A bounce can be avoided by holding spacebar
  • Prevents fall damage
  • Walking on them is slower than walking on Soul Sand, about the speed of sneaking
• Granite, Diorite and Andesite
  • Generates within Stone terrain below y=80, each in veins similar in size and abundance to Gravel or Dirt.
  • Diorite can be crafted with 2 Cobblestone and 2 Nether Quartz in a checker board pattern
  • Andesite can be crafted with 1 Cobblestone and 1 Diorite
  • Granite can be crafted with 1 Nether Quartz and 1 Diorite
  • Can be crafted, with 4 of the raw stone in a 2x2 configuration, into Polished Granite, Polished Diorite, and Polished Andesite, respectively
  • These 6 have the same data value, blast resistance, mining time, and other properties as Stone
• Crafting Recipes for blocks previously only obtainable from generated structures
  • Mossy Stone Bricks, crafted using 1 Vine and 1 Stone Brick
  • Chiseled Stone Bricks, crafted using 2 Stone Brick Slabs on top of each other, similar to Chiseled Sandstone
• An NBT tag that can lock containers
  • Mostly useful for (adventure) maps in adventure mode
  • NBT Tag in JSON format: {Lock:Key}, containers can be unlocked by clearing their string for Lock (changing it to {Lock:})
  • The lock can be cleared with the command /blockdata
  • Locked containers can only be opened while holding an item renamed to the given string
    • Example: If the value of the Lock tag is "Key" ({Lock:Key}), a player will not be able to open the chest unless they are holding an item named Key
    • Item is not removed on use
    • Only works if the item has a custom name (default names will not work)
      • Example: a chest with the tag {Lock:Diamond} cannot be opened when holding a diamond; the item held must be renamed Diamond
• A new Splash
  • "That's Numberwang!"
• A target selector that can select entities: @e
  • Can specify type of entity by entity ID to either include or exclude with [type=Chicken] or [type=!Skeleton], example: /kill @e[r=50,type=Chicken]
• A new command: /blockdata
  • Usage: /blockdata <x> <y> <z> <dataTag>
  • Can amend and modify the NBT data of the block at specified coordinates
