Ice Bomb

The **ice bomb** is an item that is used to freeze water into ice.

## Usage

Ice bombs can be thrown by using them, similar to an egg. They are affected by gravity.

Similar to ender pearls, there is a short cooldown before the player can throw another ice bomb. The cooldown is shown in the hotbar by a white overlay that shrinks before the player is able to use it again.

Ice bombs explode upon hitting most blocks, including non-solid blocks, but not air. They also explode upon hitting other entities, but they do not deal damage, and unlike eggs and snowballs, the impact is not considered an attack and does no damage or knockback. When exploding, any water (including flowing water, but not waterlogged blocks) in a 3×3×3 cube around the ice bomb freezes into ice. Ice bombs can be used to contain and displace mobs in ice under water.

While endermen teleport away from arrows shot at them, they can be hit by ice bombs.

Throwing an ice bomb while underwater encloses the player in ice.

## Trivia

* In real life, mixing a sufficient amount of sodium acetate in water does solidify it, but creates hot ice (sodium acetate trihydrate) instead of normal ice.

**Discontinued games**

***Minecraft: Story Mode*** was an episodic point-and-click narrative-driven graphic adventure game based on *Minecraft*, made by Telltale Games where players had to complete chapters in order to progress, and their choices and actions had effects on the story.

***Minecraft: Story Mode - Season Two*** was the sequel to *Minecraft: Story Mode* and had a new story continuing the adventures of the original game, with elements from newer versions of *Minecraft*.

***Minecraft Earth*** was a free-to-play augmented reality spin-off mobile game where players travel to real-life locations to build structures and collect resources. It featured many unique gameplay aspects and interactions similar to the main game. The game became discontinued on June 30, 2021.
Smarter Watch

The **Smarter Watch** was a joke offhand item.

## Usage

Smarter watches were "equipped" by having them placed into the offhand slot. Upon equipping, they would display the current time above the hotbar, in minutes and seconds, with one minute of in-game time being 5/6 of a real-time second, and one in-game hour being 5/6 of a real-time minute or 50 seconds.

The smarter watch would also notify the player of statistics milestones, alongside taken damage, item specific info, crafting items and more.[*more information needed*]

## Issues

Smarter Watches are an unsupported item due to being an April Fools' joke, and therefore issues relating to them will not be fixed.
Gold Ingot

A **gold ingot** is a metal ingot used to craft various items, and also used as currency for bartering with piglins.

## Obtaining

Gold ingots are mainly obtained by smelting raw gold, gold ore and nether gold ore, or just mining nether gold ore, dropping gold nuggets. Gold generates more frequently in badlands biomes.

### Smelting

### Mob loot

Zombified piglins have a 2.5% (1⁄40) chance of dropping a gold ingot if killed by a player or tamed wolf. The chance is increased by 1% per level of Looting, for a maximum of 5.5% with Looting III.

## Usage

### Crafting ingredient

As a material for weapons, tools, and armor, gold is not a straight upgrade from iron (except in the case of horse armor). Gold has a higher mining speed and enchantability than any other material, but attack power and durability is less.

### Trading

Apprentice-level cleric villagers buy 3 gold ingots for an emerald as part of their trade.

### Repairing

Golden helmets, chestplates, leggings, boots, swords, pickaxes, axes, hoes and shovels can be repaired with gold ingots in an anvil.

### Bartering

Main article: Bartering

Piglins throw the player item(s) if the player throws or uses a gold ingot on them.

### Beacons

Gold ingots can be used to select powers from a beacon. The player must select one of the available powers, and then insert an ingot in the item slot.

A gold ingot can be substituted for an iron ingot or netherite ingot, an emerald, or a diamond.

Wheat

**Wheat** is an item primarily obtained by harvesting fully-grown wheat crops. It is used for crafting as well as to feed certain animals.

## Obtaining

### Farming

Main article: Tutorials/Crop farming

When a fully-grown wheat crop is harvested, it drops 1 wheat and 1 to 4 wheat seeds (2 5⁄7 per crop harvested on average). A wheat crop has a total of eight stages (0-7) from the time it is planted until it can be harvested. If a crop is harvested before it is fully grown, it just drops one seed. Wheat needs light to grow; a seed is destroyed if planted without light. Harvesting with a Fortune-enchanted tool increases the number of seeds dropped but does not increase the yield of wheat.

### Drops

A fox sometimes spawns holding wheat, which it always drops upon death. Alternatively, the player can drop a food item, causing the fox to drop the wheat.

ADVERTISEMENT

## Usage

### Food

When wheat is held, it causes nearby cows, sheep, goats and mooshrooms to follow the player, until either the player stops holding the wheat or goes too far away from the animal, thus leading them to lose interest.

Wheat may be used to breed cows, sheep, goats, and mooshrooms by first herding two of them together and then using the wheat on them to begin "Love Mode."

Wheat can heal a horse 1 health or lower its temper by 3% when attempting to tame it. It can also decrease the time it takes for a foal to grow by 20 seconds.

Similarly, wheat can heal a llama 2 health, and it decreases the time it takes a baby llama to grow by 10 seconds.

### Crafting ingredient

Sugar +
Egg +
**Wheat**
 Cookie
Cocoa Beans
**Wheat**

### Trading

Novice-level farmer villagers have a 25%‌[*Bedrock Edition only*] or 40%‌[*Java Edition only*] chance to buy 20 wheat for one emerald.

### Composting

Placing wheat into a composter has a 65% chance of raising the compost level by 1. A stack of wheat yields an average of 5.94 bone meal.

## Data values

### ID

*Java Edition*:

*Bedrock Edition*:

## Video

*Note: the narrator demonstrates at 0:56 that walking over wheat can destroy the crop and un-till the land. This is outdated: since version JE 1.1, wheat can be destroyed only by a player or mob jumping on it or falling on it.*

算法

算法（Algorithms）是解决问题的方法。

描述
--

**算法**是在解题过程当中使用的方法的描述，其可以形成一个完整的解题思路。并没有一个算法能解决所有的问题。一般解决一个问题的时候需要用到一种算法。

特征
--

1. 有穷性 算法必须在特定且有限的步骤中结束，不存在一个算法能执行无限次。
2. 确切性（可读性） 对于任意一个算法，必须保证其定义明确，不得有二义性、无意义的指令。
3. 可行性 算法必须可以在现有条件下执行，不能存在着超出现有条件才能执行的情况。
4. 输入 一个算法有零个或多个输入。当用函数描述算法时，输入往往是通过形参表示的， 在它们被调用时，从主调函数获得输入值。
5. 输出 一个算法有一个或多个输出，它们是算法进行信息加工后得到的结果，无输出的 算法没有任何意义。当用函数描述算法时，输出多用返回值或引用类型的形参表示。

时间复杂度、空间复杂度越低越好。

### 正确性

算法的正确性是评价一个算法优劣的最重要的标准。也是基本的标准。算法的正确性是这个算法是否可以正确的计算出，如果不能计算出正确的结果，那么这个算法是没有意义的、无用的。

### 鲁棒性

鲁棒性是指一个算法对不合理数据输入的反应能力和处理能力，也称为容错性。但是一般在OI中不常用这种特性，因为OI题目中通常保证数据是正确的。

### Mob loot

See also: Tutorials/Iron golem farming

Iron golems drop 3-5 iron ingots upon death, regardless of the way they die. The looting enchantment does not increase the amount of iron ingots dropped.

Zombies, husks, and zombie villagers have a 2.5% (1⁄40) chance of dropping either an iron ingot, carrot, or potato when killed by a player or tamed wolf. This is increased by 1% (1⁄100) per level of looting. This gives iron ingots the following chances of dropping:

* 1⁄120 (about 0.83%)
* 7⁄600 (about 1.17%) with Looting I
* 9⁄600 (1.50%) with Looting II
* 11⁄600 (about 1.83%) with Looting III

ADVERTISEMENT

## Usage

### Trading

Apprentice-level Armorer, Toolsmith, and Weaponsmith villagers buy 4 iron ingots for an emerald as their third trade.‌[*Bedrock Edition only*]

Apprentice-level Armorer villagers have a 50% chance to buy 4 iron ingots for one emerald, and apprentice-level Toolsmith and Weaponsmith villagers always offer to buy 4 iron ingots for one emerald.‌[*Java Edition only*]

### Repairing

Iron ingots are the repair items for the iron tier and chainmail and iron armor materials, and thus can be used to repair the following items in an anvil:

* Chainmail Helmet
* Chainmail Chestplate
* Chainmail Leggings
* Chainmail Boots
* Iron Helmet
* Iron Chestplate
* Iron Leggings
* Iron Boots
* Iron Sword
* Iron Axe

Netherite Ingot

**Netherite ingots** are items obtained from crafting netherite scraps and gold ingots together, as well as loot from bastion remnant loot chests. Unlike other items, they are immune to fire and lava damage. They are primarily used to upgrade diamond gear and craft lodestones.

## Obtaining

Netherite ingots are obtained by crafting four netherite scraps and four gold ingots. It is a shapeless recipe, therefore the placement of the netherite scraps and gold ingots does not matter when crafting it.

### Chest loot

ADVERTISEMENT

## Usage

Netherite ingots are crafting materials used to make netherite tools, weapons, and armor.

### Smithing ingredient

Netherite ingots can be used on a smithing table to upgrade diamond items to netherite items, as well as trim any armor piece. Data such as durability, enchantments, and custom names are preserved.

Pitcher Pod

A **pitcher pod** is an ancient bulbous seed that has a chance to be dropped by sniffers when they finish digging. It is the seed for Pitcher Plants.

## Obtaining

Sniffers occasionally bury their nose in the ground and start digging. Once the sniffer has finished digging, one pitcher pod has a chance to be dropped on the floor as an item.

Sniffers can only dig for pitcher pods in the following blocks:

* Dirt
* Grass Block
* Podzol
* Coarse Dirt
* Rooted Dirt
* Moss Block
* Mud
* Muddy Mangrove Roots

They cannot dig for pitcher pods on mycelium.

ADVERTISEMENT

## Usage

### Pitcher Crop

Main article: Pitcher Crop Farming

Pitcher pods can be placed on farmland by using, where they grow through three stages as a **pitcher crop**.

Breaking the crop before it matures drops the pitcher pod, while breaking the final stage produces a pitcher plant and does *not* yield the pod. Pitcher crops break if pushed by a piston or if their supporting farmland breaks or turns to dirt (i.e. by being trampled), dropping their usual drops.

Farmer villagers can plant pitcher pods, but cannot harvest them once they have fully grown.

### Feeding

Pitcher pods can be used to breed chickens and reduce the remaining growth duration of and chicks by 10%.

### Taming

Pitcher pods can be used to tame parrots.

Nether Wart

**Nether wart** is a fungus harvested from nether wart crops and is used to plant them, as well as being vital in the creation of potions.

**Nether wart crops** are found in nether fortresses and bastions and is used to grow nether wart in soul sand.

## Obtaining

### Breaking

Nether wart can be mined instantly with any tool. A fully mature nether wart crop yields 2–4 nether wart. This is increased by one for each level of Fortune, this allows for a maximum of 7 nether warts dropping from one crop. Less mature stages drop one nether wart, even with the Fortune enchantment.

### Natural generation

Nether wart can generate in nether fortresses in soul sand gardens around stairwells. Nether wart can also generate in the courtyards of housing unit bastion remnants. Due to only spawning in these specific structures, it's entirely possible for a nether fortress or bastion remnant to generate without nether wart (though they may still appear in the chests that generate in the fortress).

## Usage

### Brewing ingredient

Nether wart's primary purpose is to brew the awkward potion, the base for all potions, but optional for Weakness.

Water Bottle

### Crafting ingredient

 Red Nether Bricks
Nether Brick

### Trading

Master-level cleric villagers buy 22 nether warts for an emerald as part of their trades.

### Farming

Main article: Tutorials/Nether Wart farming

When planted on soul sand, nether wart grows through four stages, though the middle two stages use the same texture (the hitbox of stage 3 is three pixels taller). In *Java Edition*, the exact age can be seen using the debug screen, and the ages range from 0 to 3. Each random tick, nether wart has a 10% chance of growing one stage. At default random tick speed, each nether wart grows one age step approximately every 13653 game ticks (11.3775 minutes) on average, and fully grows from planting to harvest every 40960 game ticks (34.133333333333 minutes) on average. The growth rate is not affected by light or any other environmental factors. Bone meal cannot be used on the nether wart.

Nether wart can only be planted on soul sand. It cannot be planted on soul soil. It can grow in any dimension.

Nether wart is ready to harvest when it reaches its fourth stage (age:3). Breaking a fully grown nether wart drops 2 to 4 nether wart, while an immature one drops a single nether wart. Using a tool enchanted with fortune increases the maximum number of nether wart dropped by 1 per level, for a maximum of 7 for a tool enchanted with Fortune III.

Arc Hill Tunnel

Arc Hill Tunnel is a SLRT train tunnel.

## Description

Arc Hill Tunnel goes through Arc Hill Mountain and is located to the south of the city. It is named after the city to connects to.

## Structure

The tunnel goes through the mountain and crosses a ravine that splits the mountain. While the tunnel crosses the ravine, the sides were cut open to allow passengers to view the ravine.

## Usage

The tunnel is used by the E and G lines. During the night, only the G runs to Arc Hill, with the E ending at Mirfield.
Adventure

**Adventure** mode is a game mode intended for player-created maps, limiting some of the gameplay in *Minecraft*. In this mode, the player cannot directly destroy any blocks with any tools or place any blocks, in order to avoid spoiling adventure maps or griefing servers.

## Gameplay

Adventure mode is similar to Survival in that players receive damage from their environment, dying is possible, and players must manage hunger. However, it is different in many ways as well. In *Java Edition*, blocks can be destroyed only with an item/tool that has the `CanDestroy` NBT tag, and cannot be destroyed by the player's fist. Likewise, blocks require the `CanPlaceOn` NBT tag to be placed. In *Bedrock Edition*, similarly, `can_destroy` and `can_place_on` NBT tags are required to destroy and place blocks.

However, players are able to make use of the environment in other ways - including interacting with mobs and other entities (for example, killing them), turning a redstone mechanism (such as a lever) on or off, and trading with villagers. Additionally, players are able to craft items as they normally would in any other game mode. Another feature is that players always spawn exactly on the world spawn point, no matter where it is - unlike Survival mode, where players can spawn anywhere within a certain grid.

Custom *Minecraft* maps make good use of Adventure mode, and many custom maps are set to this game mode; players cannot break blocks or place them, therefore disallowing them to destroy the map, or add anything to it that would ruin the map. Also, it is often used to protect various multiplayer servers from griefers. Command blocks are usually used in conjunction with Adventure mode, in servers and custom maps.

Players with the ability worldbuilder set to true can break and place blocks freely on Adventure mode.‌[*Bedrock Edition and Minecraft Education only*]

A player can switch to Adventure mode from any other game mode by using the commands `/gamemode adventure` when cheats are enabled.

Clay

**Clay** is a block that can be found abundantly in lush caves, in patches in shallow surface water or converted from mud using pointed dripstone. It can be smelted into terracotta or broken into clay balls which are smeltable into bricks.

## Obtaining

### Breaking

Clay blocks can be mined with any item, but shovels are quickest. Destroying a clay block yields 4 clay balls. If broken with a tool enchanted with Silk Touch, it drops itself instead. Destroying a clay block with a tool enchanted with Fortune does not increase the amount of clay dropped.

 Tool
 Default
 Wooden
 Stone
 Iron
 Diamond
 Netherite
 Golden

1. ↑ Times are for unenchanted tools as wielded by players with no status effects, measured in seconds. For more information, see Breaking § Speed.

### Natural generation

Clay generates in large quantities on the floors of ponds in lush caves.

Clay can also generate in lush caves in the form of blobs. Clay attempts to generate 46 times per chunk in blobs of size 0-160, at any height. It can replace stone, granite, andesite, diorite, polished granite‌[*BE only*], polished andesite‌[*BE only*], polished diorite‌[*BE only*], tuff‌[*JE only*], and deepslate‌[*JE only*].

Clay is found underwater in swamps, beaches, oceans, and at the bottoms of rivers and lakes in shallow, crystal-shaped disks, disregarding adjacency to other types of blocks.

Clay generates in mason houses in plains, savanna, and desert villages, and under fisher cottages in taiga villages.

### Mob loot

An enderman holding a clay block drops the block upon death.

### Villager gifts

See also: Tutorials/Raid farming

In *Java Edition*, when the player has the Hero of the Village status effect, a mason villager might throw that player a clay block as a gift.

### Post-generation

If mud is placed above a block with a pointed dripstone underneath, the mud eventually turns into clay, although the dripstone does not deposit any water into a cauldron. This conversion does not happen in the Nether.

Clay can be placed under note blocks to produce flute sounds.

Cutting Recipe

### Cutting

The stonecutter can be used as an alternative to the crafting table to craft most stone-related blocks. All of its recipes require just one ingredient and produce one product (in varying quantities). It allows skipping steps to craft certain blocks; for example, a stone block can be directly turned into chiseled stone bricks, but requires multiple steps with crafting.

Stonecutting is also more efficient than crafting for certain recipes. Crafting stairs is more efficient with a stonecutter than a crafting table, as 6 full blocks are crafted into 4 stairs, while stonecutter yields 1 stair per full block. The recipe for cut copper is even more efficient: with stonecutting, 1 block of copper turns into 4 blocks of cut copper, allowing the amount of copper blocks to be quadrupled.

The GUI contains a block selection menu that is empty. The menu is populated with blocks that can be crafted from that particular material, only if a block is inserted into its input.

Hardcore

**This feature is exclusive to *Java Edition*.**

**Hardcore** is a variant of Survival and one of the main game modes in *Minecraft*. In this mode, the world is locked to Hard difficulty and the player cannot respawn after dying.

The key feature of Hardcore mode is that the player is not given the option to respawn upon death as they would in other game modes. Instead, there are two buttons on the death screen: "Spectate world" and "Title screen". "Spectate world" sets the player to Spectator mode and respawns the player at the world's spawn point, making them able to view and explore the world only in that mode. The "Title screen" button simply leads the player to the main menu screen; re-opening the world simply returns the player back to the same death screen as before. Respawn anchors do not resurrect players in Hardcore mode.

In addition, Hardcore mode worlds are restricted to Hard difficulty, being the second key feature.

When creating a Hardcore mode world, the *Enable Cheats* and *Bonus Chest* world options are locked to OFF. On the world selection menu, Hardcore mode worlds display dark red text reading "Hardcore Mode!"

* While in Hardcore mode, the hearts representing the player's health look different, as they include dark red marks inside the icon

Hardcore mode is specific to worlds, not players; the variable determining whether the world is in Hardcore mode is saved in `level.dat`. Thus, the player can use `/gamemode creative` (if cheats are enabled) to set themselves to Creative mode. Players in Creative mode while on a Hardcore mode world still see Hardcore mode's death screen upon death.

It is normally impossible to toggle Hardcore mode once the world has been created, though it is possible to use external programs such as NBTExplorer to change it by setting the `hardcore` tag to either 1 (hardcore) or 0 (normal).

However, it is possible to enable cheats through the *Open to LAN* feature in the pause menu. From here, the player can, while spectating the world after death, type `/gamemode survival` to bring themselves back to Survival mode, being able to play again by cheating death.

ADVERTISEMENT

## Multiplayer

Hardcore mode is an option for multiplayer, and its functions are similar to those in singleplayer. All players have Hardcore mode enabled — it is impossible to have some players in Hardcore and some not. Hardcore mode cannot be played in Realms.

Server operators can use the `/gamemode` command to change the game mode of themselves or another player.

Honeycomb

**Honeycombs** are items obtained from bee nests and beehives.

## Obtaining

See also: Tutorials/Honey farming

When a bee nest or beehive at `honey_level` 5 is sheared, it drops 3 honeycombs and angers any bees inside, causing them to attack. Having a lit campfire or lighting a fire underneath the nest or hive prevents the bees from becoming hostile.

A dispenser with shears inside can be used to shear the nest without angering the bees. The honeycomb pops out as a dropped item.

## Usage

### Signs

Using a honeycomb on a sign or a hanging sign prevents the sign from being edited.

### Waxing

Using a honeycomb on a block of copper changes the block into its waxed variant, preventing oxidation of the copper.

Footprint

The **Footprint** was a joke item from Java Edition 20w14∞, found only in the `missing` dimension.

## Appearance

This item is semi-transparent with a grey colour scheme.

ADVERTISEMENT

## Obtaining

### Dimension

Footprints were obtained only from a chest in the `missing` dimension. Only existing in 2020 April fools snapshot 20w14∞, it cannot exist in any non-April Fool's joke versions and April Fool's joke versions before or after 20w14∞. There is a maximum of 2 footprints that can be obtained legitimately in any given world.

### Cheats/Creative Mode

## Usage

As of snapshot 20w14∞, this item cannot be placed or used in any way other than a trophy. This item can be inserted and/or rotated inside of an item frame, and it has a stack limit of 64.
Amethyst Shard

An **amethyst shard** is a crystal obtained from mining a fully grown amethyst cluster or can be obtained from chests in ancient cities.

## Obtaining

### Mining

An amethyst cluster mined using a non-Silk Touch, non-Fortune pickaxe drops 4 amethyst shards. When mined using any other tool, item or mechanism (such as explosions or pistons) it drops 2 shards. The maximum amount of amethyst shards dropped can be increased with Fortune. Fortune I gives a 1⁄3 chance for eight shards, averaging 5.33 shards; Fortune II gives a 25% chance (each) to give eight or 12 shards, averaging 7 shards, and Fortune III gives a 20% chance (each) to give 8, 12, or 16 shards, averaging 8.8 shards.

If the amethyst cluster in any of its growth stages is mined using a pickaxe enchanted with Silk Touch, it drops itself rather than amethyst shards.

Ankle Monitor

The **Ankle monitor** was a joke foot item.

## Usage

Ankle monitors were equipped in the boots slot. In survival mode, when equipped, it could not be taken off. However, players in Creative mode are unaffected.

When equipped, the player would be afflicted with Slowness I.

During the night, being a certain number of blocks from the world spawn, above a certain minimum,[*check the code*] would prompt the following message in chat: "CURFEW WARNING! You are violating your house arrest! Get back by [distance] meters!"

If in the Nether or the End, a different set of messages would be cycled through which can be seen in the section below.

### Nether and End messages

* CURFEW WARNING! You are violating your house arrest! Uuuh... where are you anyway?
* CURFEW WARNING! Hello, are you there?
* CURFEW WARNING! I'm sure you have important things to do, but you need to go back!
