The '''cobweb''' is a new item introduced in [[Version history#B1.5|Beta 1.5]]. It was previously found in the terrain.png file, but had no block ID assigned to it. It is not generated or crafted in any way. Current thoughts are that spiders will nest in it, shoot the web at you to slow you down, or drop it as loot. Cobwebs are also flammable, but they can't be ignited.

  +
Moving into a cobweb limits your movement abilities. When you are "inside" the cobweb, you will move at a speed equal to about 15% of the normal walking speed. Additionally, jumping will vibrate the player, akin to jumping in a 2 block high space. dropping an item into it will make the item stick and gradually sink through it. Unlike water, however, falling into a cobweb will not prevent fall damage, although it will be delayed until you make contact with the ground.
'''Pistons''' are [[blocks]] capable of pushing or pulling adjacent blocks, depending on the direction they face.
 
The original version of this feature was a mod posted on the Minecraft Forums by Hippoplatimus.<ref>http://www.minecraftforum.net/viewtopic.php?t=247686&f=1032</ref> Pistons were added in version 1.7, along with [[Sticky Piston]]s, and the features are demonstrated by a player [http://www.youtube.com/watch?v=DlmIcB54DJI here].
 
   
  +
When cobweb is destroyed by [[shears]], [[pistons]] or a [[sword]], it drops 1 [[string]].

== Functionality ==
+
== Notes ==
  +
[[File:WebBlockIngame.png|thumb|left|200px|A cobweb.]]
  +
* Cobweb blocks can be used as air pockets in the same manner as [[Sugar Cane]].
  +
* Cobwebs can be placed on cobwebs.
  +
* Items thrown on the cobweb are also slowed and will fall down after about 20 seconds.
  +
* A block of [[Sand]] or [[Gravel]] which falls or is shot into a cobweb, will slow down, then be destroyed and become a resource after about 4 seconds. [[TNT#Primed TNT|Primed TNT]] seems to be not affected by this phenomenon, as it doesn't disappear and will eventually explode destroying the cobweb.
  +
* Animals that walk into the cobweb will slow down, even spiders.
  +
* Minecarts treat it as a solid block, like glass mixed with wool.
  +
* Players are unaffected by cobwebs when in a minecart, except when they are in the way of the cart. This allows creation of a mob-slowing tunnel that can be ridden through with ease, making safe rooms even safer.
  +
* Signs and paintings can be placed on cobwebs.
  +
* [[Ghast]]s will not see players in or behind cobwebs.
  +
* Since Beta 1.6.6, Cobwebs stop chests from being opened.
  +
* Jumping from as little as one block above a cobweb, onto it, will induce half of a heart in fall damage.
  +
* A shot [[Bow#Arrows|Arrow]] cannot pass through cobwebs and will not slow down.
  +
* Any kind of mechanism (excluding [[Dispenser]]s and [[Note Block]]s) can not be placed on top of cobwebs.
  +
* Players are unable to jump while in a cobweb.
  +
* Cobwebs can be placed on [[Sugar Cane]].
  +
* When falling into a cobweb, if a player gets into a minecart or boat before hitting the ground, they will not take the fall damage until they exit the cart/boat.
  +
* Cobwebs have proven to be useful particularly in water-filled moats 3 blocks in depth. Adding a layer of cobweb to the bottom of the moat will render any mob (or players) stuck. It is possible to get out (granted you will lose health from a near drowning experience) but most mobs will drown. This is a particularly efficient method of repelling creepers from hiding around the corner of your house entrance.
  +
* In SMP, the particles given off when breaking a cobweb '''may''' slow down whilst falling, as they appear before the cobweb block disappears. This also seems to cause them not to fly outwards, but just drop directly downwards after the cobweb disappears. This phenomenon only seems to happen if there is a considerable amount of lag on the server.
  +
* Placing cobwebs on ice will increase the slowing effect of the cobweb.
  +
* Cobwebs will slow the time of a player breaking blocks like when in water.
  +
* Cobwebs can be broken with shears or swords, but they will drop string instead of cobweb.
  +
* You can enter Cobwebs like water
  +
*In 1.5 if a cobweb is where your head is, but not where your feet and body are, you will suffocate.

Piston functions include:
 
  +
*Forum topic: http://www.minecraftforum.net/viewtopic.php?f=1020&t=295999
* Pushing (and pulling if sticky) at least 1 block, and at most 12.<ref>http://twitter.com/#!/jeb_/status/81386768913534976</ref> Pulling will always only pull 1 block, while pushing will push between 1 and 12 blocks.<ref>[[Media:Sticky_Piston_Mechanic.jpg|Sticky_Piston_Mechanic.jpg on Minecraft Wiki]].</ref>
 
* Moving the player and other [[Mob|mobs]], as well as entities.
 
* The ability to toggle fluid flows like a flood gate.
 
* Redstone triggered, so that en masse automated block is possible (e.g. piston walls and retractable bridges).
 
* Pistons can be moved by other pistons, but only when the piston is not extended.
 
 
Pistons cannot move blocks like obsidian and bedrock to avoid abuse, and any blocks with tile entities,<ref name="NoMoveBlocks" /> as moving blocks are stored as [[tile entity|tile entities]] on the piston.<ref name="TileEntityPiston" />
 
 
A basic demonstration on the functionality of pistons can be seen here:

==Trivia==
 
 
* Pistons are slightly altered from the original mod. For example, while the original Piston Mod could propel gravity-affected blocks, as well as entities and mobs several meters vertically or horizontally, vanilla Pistons do not.<ref>http://twitter.com/jeb_/status/55921671009353728</ref> However, if a gravity-affected block is sitting on an upward-facing piston, and the piston retracts, the block will fall.
 
* [[Tile entity|Tile entities]] are destroyed if they are pushed by a piston.
 
* Pistons cannot be used to 'crush' players or mobs against walls. A piston will simply pass through them if attempted.
 
* Pistons appear to be destroyed at the same rate, regardless of the tool used.
 
* If attached from up above, pistons may be able to push blocks downwards and suffocate the player or mobs. This can be very useful for mob traps.
 
* If a water spring is placed on top of a piston, it will disappear if the piston is extended.
 
*Pistons can push dropped items as well, which can be useful to collect mob grinder items on command.
 
*Pistons can't move chests.
 
 
== Bugs ==
 
*When a piston is placed facing upwards, and a block with a pressure plate on top of it is placed on the piston, activating the pressure will make the "Saving Chunks..." screen appear. In singleplayer this will, as you might understand, always make your game load to the "Saving Chunks..." screen, unless you change your spawn position in a Minecraft-editor.
 
* When gravity-affected blocks are pushed over a hole in the ground and quickly pulled back again (or pushed away with another piston), a duplicate block appears in the hole.
 
* In Beta 1.7, pushing any tile entity with a Piston would cause the game to crash with a "Saving Chunks..." screen, and could also corrupt your world. This was fixed in Beta 1.7_01.
 
*At first during the 1.7 update some pistons appeared purple.
 
* When attempting to push ice blocks, they will turn into water in their original position, and the piston head will disappear. The piston will return to normal once retracted.
 
* When Pistons point down it is possible to glitch through the pistons, demonstrated here:
 
{{#ev:youtube|4NRXY-6GFsA}}
 
* When a piston or a sticky piston is placed upwards (with the redstone input being located 1 block bellow) and a rapid pulse signal is applied to the redstone, if the player tries to break the piston or sticky piston with any item, block, tool, or hand, the piston or sticky piston will break, dropping an item, but leaving a breakable piston head in mid-air. This is demonstrated in the following video:
 
{{#ev:youtube|cMF6qBmkwW4}}
 
* Beds can be pushed lengthwise with a piston, but if pulled back with a sticky piston the bed will split in half, dropping a bed item although still being usable.) [[File:Bed_piston.jpg|thumb|Bed after being attached to a retracting sticky piston]]
 
* Powering pistons with a redstone torch in some cases seems to always consider the torch as "on", even if powered off.
 
* When a torch or redstone torch is placed on a piston and the piston is removed, the torch will float in mid-air.
 
* When a piston attempts to push a redstone wire, the game crashes with a "Saving Chunks..." screen, corrupting the world as well.
 
{{#ev:youtube|KgmSejESEbo}}
 
* When powered, both types of pistons cannot power surrounding blocks.

This article describes content that may be included in a future update. 
This content has appeared in development versions, but the full update containing it has not been released yet.

The cobweb is a new item introduced in Beta 1.5. It was previously found in the terrain.png file, but had no block ID assigned to it. It is not generated or crafted in any way. Current thoughts are that spiders will nest in it, shoot the web at you to slow you down, or drop it as loot. Cobwebs are also flammable, but they can't be ignited.

Moving into a cobweb limits your movement abilities. When you are "inside" the cobweb, you will move at a speed equal to about 15% of the normal walking speed. Additionally, jumping will vibrate the player, akin to jumping in a 2 block high space. dropping an item into it will make the item stick and gradually sink through it. Unlike water, however, falling into a cobweb will not prevent fall damage, although it will be delayed until you make contact with the ground.

When cobweb is destroyed by shears, pistons or a sword, it drops 1 string.
