Java Edition 1.5

1.5, the first release of the Redstone Update, was a major update to Minecraft (Java Edition), released on March 13, 2013, which added a number of new redstone-related blocks and a new decorative block – the block of quartz. Also included was a scoreboard system, a new texture pack format and a lighting engine optimization.

A pre-release for 1.5 was released on March 7, 2013, though the full release of 1.5 is identical to this pre-release.

Blocks

 * 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 redstone.
 * Emits constant redstone signal, the same as a redstone torch.
 * 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 cobblestone 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 the player, while a dropper “throws" items at the player.
 * Can face all 6 directions, with a different texture when facing up or down
 * Needs 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
 * 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 × 3 = Signal strength


 * 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
 * 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
 * Proportional, so 10 strength signal means twice as many items as a 5 strength signal


 * Nether quartz ore
 * Drops 1 nether quartz item when mined
 * Can be smelted in a furnace to obtain nether quartz
 * Can be legitimately obtained with Silk Touch enchantment
 * Drop more when mined with Fortune enchantment


 * Block of quartz
 * The crafting recipe is 4 nether quartz in a square
 * Decorative block


 * Quartz slab
 * The crafting recipe is 3 blocks of quartz
 * Can be placed upside down
 * Decorative block


 * Quartz stairs
 * The crafting recipe is 6 block of quartz in a usual stair recipe
 * Can be placed upside down


 * Chiseled Quartz Block
 * The crafting recipe is 2 quartz slabs
 * Decorative block


 * Quartz Pillar
 * 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 log


 * 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 are the same height as a slab. However, five layers of snow have 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
 * The block ID is

Items

Non-mob entities

 * 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
 * Only obtainable with world editors
 * Have only the entity not the item
 * Uses the same NBT format as a normal spawner


 * Minecart with TNT
