Gameplay

Enchanting

New enchantments have been added for fishing rods that change the player's luck of catching an item when fishing.
- Lure - Increases chance of catching fish.
- Luck of the Sea - Increases chance of getting treasure.

Command Format

`/summon`

/summon is a new command used to spawn, or "summon", entities.
Usage: /summon [x] [y] [z] [dataTag]

General

Particle Effects

Fishing now has many different particle effects.
- Bubbles will show up moving towards the player's bobber just before the player has something on their hook.
- It has the appearance of a fish swimming towards the hook.
Falling now has particle effects.
- The particle size depends on the distance fallen.

Changes

Blocks

Command Blocks

Command blocks now show what command they ran recently.

Dead Bushes

Dead bushes can now be placed on hardened clay and stained clay.

Ferns

Ferns and large ferns now display their coloring from foliage.png, the texture used to identify various colors for blocks (like grass, leaves, etc.) in biomes.

Flowers

Flowers are now flammable. They cannot be placed dead center on a block, but have certain variations in which they are placed, making the flowers more varied and a lot more natural.

Grass

Grass and double tall grass display their coloring from foliage.png, which was explained before.

Item Frames

Item frames now drop the item inside them when punched, then drop themselves if they are punched when empty.
They will display the name of the item they hold (if it is custom named) when looked at up close.

Melons

Melons now generate in Jungles, making them easier to find than previously.

Sugar Cane

Sugar canes now change color depending on the biome, taking their colors from foliage.png as well.
The texture is unchanged, however. This makes biome color added onto sugar cane appear different than most.

Weighted Pressure Plates

Weighted pressure plates now output a signal relative to the number of entities on them, always starting at 1 signal strength if any entities are present.
- For Light Weighted Pressure Plates, every entity adds 1 strength to the signal.
- For Heavy Weighted Pressure Plates, starting at 1, every 10 entities adds 1 strength to the signal.
  - Example: 11 entities increases signal strength to 2.

Items

Enchanted Books

Multiple enchantments can now be added onto books, and, when combined with a tool using an Anvil, they give enchantments according to the tool.

Flint and Steel

Flint and steel is now a shapeless recipe, meaning that the two items can be put next to each other in the crafting table in any order the player desires.

Written Books

Written books can now be cloned the same way maps can, but by using Book and Quills instead of Empty Maps.
The player can clone multiple copies of the same book by putting more Book and Quills in the crafting grid.

Mobs

Creepers

Creepers can now be manually exploded after igniting the mob with flint and steel.

World Generation

General

Biomes are now put into four main categories:
- Snow-Covered
- Cold
- Medium
- Dry/Warm
Biomes will now attempt to avoid getting placed next to a biome that is too different to itself.

Extreme Hills

The generation of extreme hills now tends to include more flat areas, and more extreme mountainous regions.
Stone is also now generated more frequently than in the previous versions, even outside of Extreme Hills+ biomes.

Oceans

Oceans are now smaller and take up much less of the map.

Rivers

Rivers now have gravel patches.

Swampland

The grass in swampland is greener and fluctuates more in color, depending on biome temperature.
In shallower parts, the coast is covered in staggered dirt blocks.

Taiga

Normal taiga biomes no longer receive snowfall below y=120.

Gameplay

Fishing

Some changes have been made to the mechanics to make fishing better.
- More rewards: treasure and junk.
  - Treasure: 6 items total, including:
    - Enchanted fishing rods
    - Enchanted bows
    - Enchanted books
    - Name tags
    - Lily pads
    - Saddles
  - Junk: 13 items total, including:
    - Damaged fishing rods
    - Water bottles
    - Rotten flesh
    - String
    - Leather
    - Bowls
    - Sticks
    - Bones
    - Tripwire hooks
    - Ten stacked ink sacs
    - Damaged leather boots

Fog

The distance for fog has been increased.

Command Format

`/give`

/give can now give items to players with custom names and lore.
The command can also give enchanted items.
- Example: /give {display:{Name:"",Lore:["",""]},ench:[0:{id: ,lvl: }]}
The command can also give items to players with custom NBT tags, such as SkullOwner to obtain the Head of a specific player.
- This removes the necessity to use an NBT editing program to obtain these items.
Attribute modifiers have also been added to the /give command.
- Example: To give a diamond sword with +50 Attack Damage to the nearest player, use the command /give @p 276 1 0 {AttributeModifiers:[0:{AttributeName:"generic.attackDamage",Name:"generic.attackDamage",Amount:50,Operation:0,UUIDLeast:894654,UUIDMost:2872}]}
- This enables the possibility of additional attributes to items using commands without the use of an NBT editing program.

`/time set day`

/time set day now sets the time to 1000 instead of 0.

Scoreboard

Scoreboards can now use statistics to create objectives; anything that statistics can track can be used as an objective.
They can also track achievements.
- This is the reason why statistics/achievements were changed to be stored per world/server.

General

Achievements

There has been a rewrite of the achievement system.
- Achievements are now per world/server instead of per player.
744 new objective criteria have been added.
New achievements:
- Repopulation: Breed two cows with wheat
- Adventuring Time: Discover all biomes
- The Beginning?: Spawn the Wither
- The Beginning.: Kill the Wither
- Beaconator: Create a full Beacon
The achievements screen can now be zoomed in and out using the mouse wheel.
Achievements don't appear on the achievements screen if more than five achievements need to be achieved first.
- Example: "DIAMONDS!" doesn't appear until "Getting Wood" is achieved.

Controls

The Key Config has been rewritten.
- Function and sprint keys can be changed.
  - By default, sprinting can be activated by holding down the left control key.
    - In Creative mode, this can also be done while flying.
- The original sprinting controls (double-tap forward or double-tap backward while holding down forward) still function.
- Smooth mouse, formerly available by pressing F8, will now use F4 by default.

Inventory

The display item for the Decoration Blocks tab in the Creative mode inventory is the Peony, changed from the old Rose flower.

Lighting

A lot fewer "black spots" appear in the terrain generator. Because of this, torch bugs in strongholds and mineshafts have been fixed.

Options

Several option screens have been rewritten.
A completely new options menu, the "Select Resource Pack" menu, has been added as well.

Resource Packs

The ability to select multiple resource packs at once has been added.
- Resource packs at the top take precedence over those below.
- This allows for non-manual merging of textures from multiple packs, a sound pack, and a different texture pack, etc.

Statistics

New statistics have been added:
- Distance by Horse
- Animals Bred
- Junk Fished
- Treasure Fished
The statistics system has also been rewritten.
Statistics now tie in with the scoreboard system.
744 new objective criteria that were previously tracked with statistics and achievements have been added.
Much like achievements, these are now per world/server.
Data for a block, item, or mob doesn't appear in their respective tab in the Statistics screen unless the player has crafted/placed/mined that block, crafted/used/depleted that item, or killed/was killed by that mob.

Sounds

The volume of in-game music, Jukebox and Note Block music, hostile mobs, passive mobs, players, weather, blocks/environment, and the master volume can now all be modified separately.

Additions

Command Format

`/setblock`

/setblock is a new command that places blocks without the use of FallingSand.
- Syntax: /setblock <x> <y> <z> <TileName> [dataValue] [oldBlockHandling] [dataTag]
  - Valid values for oldBlockHandling: "replace" to place the specified block (throws error message if the same block exists already), "keep" will only place blocks in air, and "destroy" will mine the existing block and drop an item before placing the new block.

`/testforblock`

/testforblock checks for blocks in specific locations.
- Syntax: /testforblock <x> <y> <z> <TileName> [dataValue] [dataTag]
- All blocks beyond X/Z 30 million (±30,000,000) from origin now act as solid blocks, and cannot be targeted with the crosshair.
  - This includes air blocks.
  - This creates essentially an invisible wall which extends infinitely, even above and below the chunks.
- As all blocks function as solid, if the player is moved outside the boundary via external tools, they will be unable to move outside the block space they are within.
  - Despite the above, the camera can still move normally.
    - This reveals that ghost chunks still generate, as the camera can pass through normally solid blocks beyond the boundary.

Changes

Blocks

Command Blocks

The character limit for command blocks has been increased to "many thousand characters", according to Dinnerbone.

Lava

Lava source blocks can no longer be destroyed by explosions.

Technical Blocks

The item forms of many blocks have been removed:
- Bed (26)
- Piston head and extension (34 & 36)
- Redstone wire (55)
- Wheat crops (59)
- Standing and wall sign (63 & 68)
- Wooden and iron door (64 & 71)
- Lit redstone ore (74)
- Unlit redstone torch (75)
- Sugar cane (83)
- Cake (92)
- Unpowered and powered repeater (93 & 94)
- Locked chest (95)
- Pumpkin and melon stem (104 & 105)
- Nether wart (115)
- Brewing stand (117)
- Cauldron (118)
- Lit redstone lamp (124)
- Tripwire (132)
- Flower pot (140)
- Skull (144)
- Unpowered and powered comparator (149 & 150).
- These items can no longer be obtained with /give, but can be created with /setblock.
- Because the game is still told to drop a Lit Redstone Lamp when mining a lit lamp with Silk Touch, doing so will result in a Null Pointer Exception crash as such an item no longer exists.

World Generation

Mesa

The mesa biome generation has been slightly changed to appear more layered.

Gameplay

Nether Portals

Nether portals can be planned to have odd width to allow for design variations.
- They can be built large enough so that Ghasts can enter the Overworld.
- Portals can now be activated from any block within the portal, not just the bottom (when any fire block appears inside the frame).
- There are now new nether portal building rules: Any size from 4×5 to 23×23, but the designs have to be rectangular.

Command Format

`/give`

/give will now print renamed items' name in chat and show tooltips when hovered over.

Block/Item IDs

Block and items can now be referred to with names instead of IDs.

General

Chat System

The chat system has been updated to be more "useful to map makers, modders, players and server admins".
- A way to do things when clicking things in chat, like executing a command, has been added.
  - Other actions include opening a URL and showing an item tooltip when hovered on.
- "Saved screenshot as" messages can now be clicked to open the screenshot; this takes players to the .minecraft folder.
- Names can now be clicked to PM people.
- The command /tellraw <player> <raw json message> has been added as well. The command is used to send chat messages with custom functionality to players - sender will not appear.
  - Syntax example: /tellraw @p {text:"Daytime? ",color:"green",extra:[{text:"Click here!",color:"blue",clickEvent:{action:"run_command",value:"/time set day"}},{text:" Nighttime? "},{text:"Click here!",color:"blue",clickEvent:{action:"run_command",value:"/time set night"}},{text:" Have fun!"}]}

Additions

Command Format

Commands

The command /setidletimeout <minutes until kick> has been added.
- The command is used to automatically kick idle players after a set length of time.
- This is a multiplayer-only command, and can be used only by server operators.

  - Temple.dat (desert temples, jungle temples, and, strangely, witch huts)
  - Stronghold.dat (strongholds)
  - Mineshaft.dat (mineshafts)
  - Others are also included for other generated structures.
The NBT structure consists of the individual parts of each structure, labeled "children," the chunk it originates in, a tag called BB, and an ID for what type of structure it is.
- The children tags have information on each part of the structure and the type of part it is.

General

Achievements

The achievement "Diamonds to you!" has been added. It is obtained by throwing diamonds at another player.

  - For example, running a command block minecart across a single powered activator rail at full speed will run its command thrice.
- They can be success-tested while on a detector rail with a redstone comparator next to the rail (just like how the minecart with chest and minecart with hopper can be fill-checked).

A desynchronization issue that appeared at high coordinates has been fixed. This varied depending on hardware.
