Minecraft:Cobweb

Template:Infobox block A cobweb is a Minecraft:block that drastically slows down the movement of most entities touching it. The Minecraft:Weaving effect lessens this movement speed decrease.

Obtaining

Breaking

Cobwebs can be obtained as an item using Minecraft:shears. Cobwebs can also be obtained with a sword enchanted with Minecraft:Silk Touch, which is possible only through commands or while in Creative modeTemplate:Only. A cobweb drops one piece of Minecraft:string if broken with a non-Silk Touch sword, if Minecraft:water touches or flows over it, or a Minecraft:piston pushes it. Breaking cobwebs costs two durability on a sword. It drops nothing when broken using anything else, or if Minecraft:lava flows over it.

Natural generation

Cobwebs generate naturally in Minecraft:mineshafts, Minecraft:stronghold libraries, Minecraft:igloo basements, Minecraft:abandoned villages, Minecraft:woodland mansion spider spawner rooms, and Minecraft:trial chambers around specific Minecraft:trial spawners.

Post-generation

When an Minecraft:entity with the Minecraft:Weaving effect dies, 2–3 cobwebs can generate in a 3×3×3 cube centered on the entity's location of death. The cobwebs can generate only on top of blocks with a full top face, meaning that cobwebs cannot generate on top of other cobwebs. When the Minecraft:game rule Template:Cd is set to Template:Cd, entities excluding the player do not generate cobwebs upon death.

Usage

Minecraft:Mobs can spawn inside of cobwebs. Cobwebs also diffuse sky Minecraft:light. Minecraft:Undead mobs do not catch fire from sunlight if they are under a cobweb or their head is inside a cobweb.

Blocks can be placed on cobwebs. Minecraft:Paintings Template:Only and Minecraft:signs can be placed on their sides, or on top in the case of signs.

Despite being slowed down by them, mobs do not try to pathfind around cobwebs, which can be exploited to construct clever mob traps.

Redstone circuits

2 cobwebs delay for around a minute

Cobwebs can be used as a delaying mechanism in a redstone circuit, for example, to delay an item falling on a Minecraft:pressure plate or into a Minecraft:hopper. They can also be used to cancel random momentum of an item thrown from a Minecraft:dispenser or Minecraft:dropper by placing them directly on their face.

Effects

All mobs except for Minecraft:spiders, Minecraft:cave spiders, Minecraft:shulkers and Minecraft:vexes experience slow movement through a cobweb and, if affected by gravity, fall approximately 0.078 blocks/second while within it, taking nearly 13 seconds to fall 1 full block. A cobweb can partially stop blast damage if a player/Minecraft:entity and another entity causing the Minecraft:explosion are both caught in the cobweb.

Cobwebs halt item entities' horizontal momentum completely and make item entities fall around twice as slow as mobs do, taking ~27 seconds to fall 1 full block. Experience orbs, on the other hand, would fall approximately ~2.54× slower than mobs, taking ~33 seconds.

A cobweb affects the Minecraft:player's movement abilities, as well. While in contact with it, the player can move at a speed of about 25% of the normal walking speed, and their Minecraft:jumping height is severely reduced. A cobweb also limits the rate at which a player can Minecraft:break blocks. Like Minecraft:water, falling into a cobweb prevents a player from taking Minecraft:fall damage, meaning a fatal fall can be mitigated with cobwebs. Attacking while falling through cobwebs counts as a Minecraft:critical hit, the same as when falling after a jump.

Players and mobs affected by the Minecraft:Weaving effect move through cobwebs at 50% of their normal speed instead of 25%.

The slowing effect of the cobweb increases if it is placed on Minecraft:ice. The slowest a player can move in vanilla Minecraft without commands or other third-party tools is by placing cobwebs on Minecraft:blue ice, Minecraft:sneaking, drinking a level IV Minecraft:Turtle Master potion, and Minecraft:blocking, which causes the player come to a near-total standstill, moving only a single block every few minutes.

Minecraft:Items thrown into a cobweb are slowed and fall through it after a maximum of about 24 seconds depending on where it enters. They do not merge with other items of the same type thrown on the ground.

Cobwebs have different effects on other moving Minecraft:entities. An Minecraft:arrow shot at a cobweb passes through without being slowed. Template:IN, a Minecraft:falling block that enters a cobweb slows down, then drops as an item after existing for 30 seconds.

A Minecraft:minecart with no players in it takes about 9 seconds to fall through a cobweb if a Minecraft:rail is placed directly under the cobweb, however, if there is air between the cobweb and the rail, the minecart takes about 34 seconds to fall. Every extra cobweb added gives an additional 25 seconds of falling time. Players are unaffected by cobwebs when in a minecart unless they come into direct contact.
