Gameplay

Additions

• Scoreboard system

    • Good for PVP servers.
  • Used via /scoreboard command or command block
  • The scoreboard can be used to track deaths, players killing another player, players killing a mob, or players activating commands

  • Has team mechanics including custom name colors, friendly fire options and objective tracking per team instead of per player
  • Displays points below players nametags
  • Invisible players on a team can be seen using the SeeFriendlyInvisibles NBT tag
• Commands
  • /testfor command
    • Tests for whether specified player is online (testfor [player]), or at specified coordinate and/or in radius (testfor @p[x,y,z], testfor @p[r=radius] or testfor @p[x,y,z,r=radius])
    • Signal output to any Redstone Comparators surrounding the command block like testing content of a chest
  • /effect command
    • Usage: /effect <player> <effect> [seconds] [amplifier]
    • To remove effects: /effect <player> <effect> 0

Blocks & Items

Additions

• Activator Rail
  • The crafting recipe is 2 sticks, 6 iron ingots and 1 redstone torch
  • Used to trigger Minecart with TNT
  • Used to stop item passing on Minecart with Hopper
  • Needs to be powered by redstone
  • Transmits redstone signal to 8 Activator Rails far
• Block of Redstone
  • The crafting recipe is 9 Redstones
  • Stores 9 Redstone
  • Emits constant redstone signal
  • Works as pushable redstone power source
• Daylight Sensor
  • The crafting recipe is 3 Wooden Slabs, 3 Nether Quartz and 3 Glass blocks
  • Outputs a signal with a strength corresponding to the intensity of the sun
  • Only works with the sun's light (not man made light such as torches)
  • Rain affects the sensor's output
• Dropper
  • The crafting recipe is 7 Cobblestones and 1 Redstone
  • Places items in containers in front of them, if there is no container it will dispense the item without using it
  • A dispenser 'shoots' items at you, while a dropper 'throws' items at you^[6]
  • Can face all 6 directions, with a different texture when facing up or down
  • Need redstone signal to drop items
  • Fires once when the input becomes powered
  • Redstone signal emitted when a Redstone Comparator is placed against it directly - signal length depends on its fullness
• Hopper
  • The crafting recipe is 5 iron ingots and 1 Chest
  • Places and takes out items in Hoppers, Chests, Furnaces, Minecart with Chests, Minecart with Hoppers, Dispensers, Droppers, and Brewing Stands
  • Allows for the automation of many processes collecting drops
  • Powering the Hopper stops it from [taking] in items and releasing them^[7]
  • Redstone signal emitted when a Redstone Comparator is placed against it directly - signal length depends on its fullness
    • 1 item will give a signal strength of 1, a third of a stack (21 for items which stack to 64) gives a signal strength of 2
    • The number of full stacks x 3 = Signal strength
• Minecart with Hopper^[8]
  • Crafting recipe is a hopper on top of a minecart
  • Can only be emptied by passing over a hopper
  • Can pick up items from containers when it passes over
• Minecart with Spawner entity^[9]
  • Only obtainable with world editors
  • Have only the entity not the item
  • Uses the same NBT format as a normal Spawner
• Minecart with TNT
  • The crafting recipe is 1 TNT and 1 Minecart
  • Triggered by Activator Rails
  • Explodes even more violently the faster it goes
  • In Creative mode when left clicked while moving, the Minecart with TNT explodes
  • Doesn't destroy rails and supporting blocks
  • Still blows up redstone materials
• Redstone Comparator
  • Based on the idea of the Capacitor mentioned at Minecon 2012
  • The crafting recipe is 3 Redstone Torches, 1 Nether Quartz and 3 Stone
  • It is the same as a repeater, but with 2 inputs
    • If input A is stronger or equal to input B, it either repeats the signal or outputs the difference between A and B, so this can be used as an easier way make redstone contraptions like Piston Doors
      • Output is toggleable by right clicking
    • If input A is weaker than input B, then there is no output
  • All containers output a redstone signal when a Redstone Comparator is placed against it directly. The strength of it depends on how full the container is and what disc number is used in a Jukebox
    • This works with Trapped Chests as well, meaning it can provide two redstone signals with different causes at the same time
• Trapped Chest
  • The crafting recipe is 1 Chest, and 1 Tripwire Hook
  • Gives out a signal depending on the amount of players looking inside
  • Large Trapped Chests can be staggered with Large Chests to allow more compact storage
  • Transmit signal downward through one block. This does not apply horizontally^[10]
  • Texture is slightly different than a normal chest, with a red stain around the latch
• Weighted Pressure Plate
  • Used to detect item drops
  • Gold(light) version reaches full strength at 60 items
  • Iron(heavy) version reaches full strength at 600 items
  • Linear, so 10 strength signal means twice as many items as a 5 strength signal
• Nether Brick (item)
  • Obtained by smelting Netherrack
  • Used to make Netherbrick
• Nether Quartz
  • Picked up when you break or smelt Nether Quartz Ore
  • Is a crafting ingredient for Daylight Sensors and Redstone Comparators

  • Decorative block
• Pillar Quartz Block
  • The crafting recipe is 2 vertical Block of Quartz
  • Decorative block
  • Pillar Quartz Blocks can be placed sideways, using the side of the block to place similar to sideways Wood
• Multiple snow heights
  • Fully implemented - previously, a world editor could be used for different heights of snow
  • Drops one snowball for every layer of snow
  • Each level of snow has its own height collision
    • The topmost layer of snow does not have collision, so the player is always slightly sunken in the snow
    • Visually, four layers of snow is the same height as a slab. However, five layers of snow has the same collision height as a slab
  • Crafting recipe is 3 snow blocks in a row to create 6 snow layers
    • For each thin layer of snow crafted, the player loses exactly half the snowballs required to produce it
• Sandstone Double Slab
  • Place two sandstone slabs on top of each other
  • The block ID is 43:9
