Java Edition 1.9

1.9, the first release of the Combat Update, was a major update to Minecraft (Java Edition) that was released on February 29, 2016. This update completely revamped combat by adding a timed attack system, dual wielding, spectral and tipped arrows, and shields. The End was revamped with an updated ender dragon boss fight sequence, an expanse of additional End islands with chorus plants, end cities, end ships, purpur blocks, shulkers, as well as elytra, which a player can wear to glide through the air. It received a lot of backlash from the PvP community after launch due to the changing mechanics of combat. Many servers chose not to update to 1.9, and are still like this today.

 * Tree-like arrangements of the new chorus plant and chorus flower blocks.
 * The whole structure is destroyed when the bottom-most block is destroyed, like cacti.
 * Can be farmed by planting the chorus fruit flowers that come from the top of the plants, on top of endstone.
 * Unlike cacti, chorus plants do not require the supporting block to be below it, but rather adjacent.
 * This allows the structure to grow around obstacles, like other chorus trees.


 * The End
 * Generates many islands in every direction from the main island, though separated by a gap of about 1,000 blocks.
 * Mini islands generate between the center and main islands.
 * End islands and mini end islands (except for the main one) will have chorus trees spread throughout them, as well as end cities with end ships.

 * Resembles a tree house.
 * Contains loot inside of chests.
 * Generates with shulkers in it.

 * It consists of the gateway block in the middle and two little bulbs of bedrock on the top and bottom.
 * Since the bulbs of bedrock only leave a one block slit on the horizontal plane, it is only accessible by throwing ender pearls at it, or by riding pigs, boats or minecarts.
 * When used, it generates another gateway at the player's destination.
 * The gateways are linked so the player has a way back.


 * End ship
 * Sometimes generates up in the air next to the end city dungeon.

 * Igloos
 * Spawn randomly in ice plains and cold taiga (but not the Hills variant).
 * Spawning parameters are shared with desert temples, jungle temples, and witch huts: the fact of a structure spawn is decided, then the biome determines which structure (if any) is spawned.
 * An igloo contains: 9 white carpets, 3 light gray carpets, 2 blocks of ice, a redstone torch, furnace, bed and a crafting table.
 * Some igloos have a stone brick basement, with a cauldron, 2 red carpets, a brewing stand, 3 spruce stairs, a cobweb and loot chest, along with a villager priest and zombie villager priest in iron bars. A trapdoor with ladders leads down, into the mossy brick basement, cracked and stone brick also available, with 2 torches.
 * In the loot chest there is a golden apple, hinting that the player needs to cure the Zombie.
 * Always spawns with a splash potion of weakness hinting the player to use these on the zombie to turn him into the villager next to him.
 * The zombie has the PersistenceRequired tag which makes it not despawn.
 * Silverfish spawn in some stone brick blocks.


 * Superflat
 * New preset: The Void
 * Spawns the player on a stone platform. No other terrain generates.
 * The Void is now a biome with an ID of 127.

Gameplay

 * Combat
 * New "attack strength" combat mechanic.
 * A meter shows up after switching items or attacking.
 * Damage done depends on the fullness of the meter, with a quadratic reduction (attack does 20%–100% of normal damage as the meter fills).
 * Fills at different rates depending on the new attack speed attribute (see table on the changes to gameplay section for a complete list).
 * The effect will cause the meter to fill faster
 * Can be displayed next to the hotbar (left or right based on the player's main hand), under the crosshair or turned off.
 * Looks like the icon for the effect on the side of the hotbar, or like a dagger under the crosshair.
 * This is controlled in video settings.
 * A cooldown animation is displayed of the tool slowly being lifted up, when first switching to it.
 * Play sounds when attacked strongly, weakly, and parried.


 * Dual wielding
 * Players can now use both hands to perform different actions using the left and right mouse buttons.
 * For example, if a player has a pickaxe in their main hand and a torch in their other hand, right clicking will place the torch.
 * This happens because a pickaxe lacks a right click use, and therefore the game tries to then treat the other item as if it's being right clicked.
 * The player cannot click both buttons at the same time.
 * This is achieved through an extra inventory slot called the "offhand" slot.
 * Pressing (by default) will switch whatever item is selected in the hotbar with the item in the offhand (including no item).
 * The offhand slot is displayed next to the hotbar when it's not empty (left for right-hand players and vice versa).
 * It's available on all iterations of the inventory screen.
 * It is distinguished by an outline of a shield like symbol.
 * The player can hear an item switching sound, only for other players.
 * The player cannot hear their own items switching.
 * Only the main hand can be used for physical attacks.
 * Bows choose their arrow type based on the offhand.
 * Arrows in the offhand take priority over arrows in any other slot.
 * If there are multiple arrow types and none in the offhand or selected hotbar slot, the arrow that is in the lowest numbered slot will get fired.
 * The offhand model is invisible in first person view while it's empty.
 * Some attributes and enchantments will apply to the offhand item, if specified through a new tag.


 * Enchanting
 * "Treasure" enchantments
 * Can only be obtained from chest loot, fishing, or trading for enchanted books.
 * New "treasure" enchantment: Frost Walker
 * Turns water into meltable ice which decays in multiple stages.
 * Does not work on flowing water.
 * Different tiers:
 * Level I creates a circle of frosted ice around the player with a radius of 2 blocks.
 * Each additional level adds 1 to that radius.
 * Maximum radius is 16 blocks
 * Levels over 14 don't increase the range
 * Will not turn water into frosted ice if an entity is in that spot.
 * The water must have an air block above in order to be turned into frosted ice.
 * Works as long as the player is with in one block above a block.
 * Cannot be combined with Depth Strider enchantment.
 * New "treasure" enchantment: Mending
 * Any experience collected while holding the item repairs it instead of going to the experience bar.
 * Mainhand, offhand, and armor slots all count as held.
 * If multiple held items have the enchantment, one will be chosen at random for each experience orb collected.
 * Repairs at a rate of 2 durability per experience.
 * If the amount of repair needed is less than the value of the experience orb, the extra experience will go to the experience bar.


 * Status effects
 * Received when players or mobs are hit by spectral arrows.
 * Makes player's outline glow, even through non-transparent blocks.
 * Listed as a negative effect because it prevents players from hiding from other players.
 * It becomes colored differently if the player is part of a team to match its team color.
 * Received when the player or mobs is hit by shulker projectiles.
 * Makes player involuntarily float high into the air.
 * Can be used to get to higher places.
 * Listed as a negative effect due to the potential to kill from fall damage.
 * Higher levels of levitation result in faster floating.
 * Effect levels 128-254 result in floating downwards at a constant speed, with level 128 being the fastest and level 254 the slowest (one block per second).
 * Effect level 255 disables falling and jumping altogether, to an effect not entirely unlike flying in creative mode. Gaining or losing elevation is impossible without using pistons.
 * and
 * Increases/Decreases the luck attribute by ±1 per level.
 * and
 * Increases/Decreases the luck attribute by ±1 per level.


 * Transportation
 * The player can now glide using elytra
 * The player can also use the new "Elytra Control" option.

 * For example, the armor stand in the following command is at the bottom of the stack while the cow and pig are at the same depth:
 * One may also summon entities in stacks instead of the same height and with specific NBT tags attached to it:
 * All mobs

 * e.g.
 * (long): Seed for generating the loot table. Used in vanilla survival to replicate chest content in new worlds with same seeds. 0 or omitted will use a random seed.
 * Entity: MinecartHopper
 * (byte): Determines whether or not the minecart hopper will pick up items into its inventory.
 * e.g.

 * Non-conditional command blocks will always be 1.
 * e.g.
 * Tile: Command blocks & note blocks
 * (byte): now have the "powered" tag associated with them, stating whether or not the block is currently receiving a redstone signal.
 * They can be edited through block data so the block are activating even though no redstone is adjacent.
 * Changing a command block through the "always active" toggle, effectively makes that command block to always have a 1 powered state, even when the block is updated.
 * e.g.
 * Tile: Brewing stands
 * (byte): Stores how much fuel is remaining in a brewing stand
 * e.g.
 * Tile: End gateway portal (minecraft:end_gateway)
 * (compound): Holds a set of X/Y/Z coordinates to determine the general location the player will be "safely" teleported to when entering.
 * (byte): When set to 1, it will teleport entities to the specified coordinates exactly instead of at a safer location around those coordinates.
 * (long): Determines how long the end gateway has existed.
 * When lower than 200, the block will emit a purple beam.
 * This is to easily locate the gateway when it first spawns.
 * e.g.
 * Scoreboard
 * Added
 * The player can add and remove tags for any entity based on NBT tags of that entity/player.
 * e.g.  will add the tag "test" to all players that are in the air.
 * Tags can be accessed by using the parameters after the selector.
 * e.g.  will give 1 stone to all players that have the tag "test".
 * The player can use  to see what tags are on an entity.
 * Tags are stored in the  file as strings, not in the scoreboard files.
 * This means that any tag the player binds has to be bound to an existing online player or an existing entity.
 * Unlike objectives, tags cannot be displayed anywhere on the HUD or inventory.
 * Only via the list sub-command can the player see which tags an entity has on the chat.
 * Through  it is possible to obtain the number of scoreboard tags an entity has via.
 * Added five new objective types: XP, hunger, oxygen, armor and level.
 * "xp" can be used to track the players exact amount of XP points.
 * "food" can be used to track the hunger level of the player (ranges from 0 to 20).
 * "air" can be used to see how long the player has been underwater.
 * Starts at 300 (out of water) and then decreases 1 per tick as long as the player´s head is underwater (resets when the player gets out of the water).
