It is the first snapshot released in 2013. == Additions == === Blocks === ; [[File:Block of Redstone JE1 BE1.png|32px]] [[Block of redstone]] * Stores redstone dust similar to [[blocks of diamond]], etc. * Emits constant redstone power. * Works as a pushable redstone power source. ; [[File:Daylight Detector.png|32px]] [[Daylight sensor]]s * Output power while receiving sunlight. * The level varies depending on the time (more sunlight = more redstone power), and it does not function at night. ; [[File:Hopper (D) JE1.png|32px]] [[Hopper]]s * Places and takes out items in hoppers, [[chest]]s, [[furnace]]s, [[minecarts with chests]], [[dispenser]]s, and [[brewing stand]]s. * Allows for the automation of many processes. * Still a work in progress (as indicated by the inventory icon [[File:Hopper (item) JE1.png|32px]]). ; [[File:Nether Quartz Ore JE1 BE1.png|32px]] [[Nether quartz ore]] * New ore exclusive to the Nether. * Drops 1 [[nether quartz]] item when mined. * Generates around [[netherrack]]. ; [[File:Redstone Comparator (S) JE1.png|32px]] [[Redstone comparator]] * Has 3 inputs and 1 output. Input from the back is considered signal A, and whichever side gives the stronger signal is considered signal B. * Has 2 modes: comparison and subtraction. * In comparison mode, if A≥B, the output is A, otherwise output stays off. * In subtraction mode, if A≥B, the output is A-B, otherwise output stays off. * Replacement for the "capacitor" idea. ; [[File:Trapped Chest.gif|32px]] [[Trapped chest]]s * Gives out a signal depending on the amount of players looking inside. 1 player = 1 strength signal, 2 players = 2, etc. * Crafted with a [[chest]] and a [[tripwire hook]]. * Large trapped chests can be staggered with large chests to allow more compact storage. * Texture is slightly different than a normal chest, with a red stain around the latch. ; [[File:Light Weighted Pressure Plate JE1 BE1.png|32px]] [[File:Heavy Weighted Pressure Plate JE1 BE1.png|32px]] [[Weighted pressure plate]]s * Detects item stacks. * [[Light Weighted Pressure Plate|Gold]] version reaches full strength at 60 items. * [[Heavy Weighted Pressure Plate|Iron]] version reaches full strength at 600 items. * Linear, so 10 strength signal means twice as many items as a 5 strength signal. === Items === ; [[File:Nether Brick JE1 BE1.png|32px]] [[Nether brick]] * Used for crafting [[nether bricks]]. * Obtained by smelting [[netherrack]]. ; [[File:Nether Quartz JE1 BE1.png|32px]] [[Nether quartz]] * Item dropped from [[nether quartz ore]]. == Changes == === Blocks === ; [[File:Locked chest JE4.png|32px]] [[Locked chest]]s * Texture for the block was changed from [[File:Locked chest JE3.png|32px]]. ; [[Piston]]s * Are more stable from previous versions. ** Sticky pistons are less sticky. ; [[Redstone circuit]]s * Are now more consistent. === Items === ; General * Now shows the item name in-game. === Gameplay === ; [[Death messages]] * Now show the weapon someone was killed with. ; Inventory management * Double-click items to fill the stack up as much as possible. * Drag item stacks around to divide them up over the dragged-over slots. * Drag item stacks around with the right mouse button to place one of that stack in each dragged-over slot, if that slot is not occupied already. * Shift double-click an item stack to move all other item stacks of that kind to that part of the inventory. * Press {{key|Q}} while the mouse is over an item in the inventory or a container to drop it. == Bugs == * [MC-5711] Redstone torches attached to the side of a block do not pop off if the block supporting them is destroyed. * [MC-5721] Dragging to spread an item out in the Creative inventory, then clicking on the inventory tab, and placing the 0 stack item down, the game crashes. * [MC-5728] Infinite loop caused by subtraction mode comparators causes the world to be unplayable. * Mineral duplication: players can exponentially dupe minerals by putting then in a crafting table with a block of their material, then double clicking on a mineral in the crafting table, works on the same principle as the method below. * Crafted item duplication: any stackable crafted item can be duplicated by setting up its recipe in a crafting table, then double clicking an existing version of this item in the inventory. Requires at least one of that item to be present in the inventory. == Fixes == {{fixes|fixedin=13w01a|prefix=Snapshot |;old |177|''[12w26a]'' Clocked piston arm turns invisible when exiting game/dying/etc. |184|''[Beta 1.2]'' (Powered) redstone doesn't update right. |5621|''[Beta 1.7]'' Blocks like redstone dust, repeaters, doors, and levers don't drop when the underlying block is pushed by a piston. }} == Gallery == 13w01atorches.png|A bug with torches in this version. == Trivia == * Along with [[18w01a]], 13w01a was released on the earliest calendar year out of all snapshots, on January 3. ** Until this point, the snapshot released on the earliest calendar year out of all snapshots was [[12w01a]] on January 5. * 13w01a is the first snapshot to feature a [[version banner]] alongside the official changelog. == References == {{reflist}} == Navigation == {{Navbox Java Edition versions|1.0}} [[de:13w01a]] [[es:Java Edition 13w01a]] [[fr:Édition Java 13w01a]] [[ja:Java Edition 13w01a]] [[ko:Java Edition 13w01a]] [[lzh:一三週〇一甲]] [[pt:Edição Java 13w01a]] [[ru:13w01a (Java Edition)]] [[uk:13w01a (Java Edition)]] [[zh:13w01a]]
