Minecraft:Sticky Piston: Difference between revisions

Template:For Template:Earth hatnote Template:Infobox block A sticky piston is a variant of the Minecraft:piston that can additionally pull most blocks when it retracts.

Obtaining

Breaking

A sticky piston can be broken using any Minecraft:tool with equal efficiency, and always drops itself. Template:IN, it is faster to break them with a Minecraft:pickaxe. The pickaxe is also the preferred tool for breaking the head when extended.<ref>Template:Bug</ref> Template:Breaking row

Natural generation

Three sticky pistons generate as part of each Minecraft:jungle pyramid. Five sticky pistons also generate in each Minecraft:ancient city.

Crafting

Template:Crafting

Usage

Template:See also A sticky piston behaves the same way as a normal piston, except when pulling. A sticky piston pulls when it is unpowered.

Template:IN, the start delay is fixed at 1 Minecraft:redstone tick which is Template:Convert, meaning that the sticky piston starts to extend or retract 1 redstone tick (2 game ticks) after it is activated. Sticky pistons can only activate on the input/consumer redstone tick (Minecraft:C-tick).

Pulling

A sticky piston also pulls the block attached to its head and any blocks attached to the head via slime- or honey blocks, but not any of the other blocks it may have pushed.

A sticky piston cannot pull a falling block.

Block dropping

Template:Exclusive A sticky piston finishes extending early and starts retracting if it loses power before the extension process is over (assuming it can detect the signal change). If the sticky piston was pushing one or more blocks during the extension, the first block ends up in its final position immediately and all the other blocks continue moving as if they were still being pushed.

This behavior is intended<ref>Template:Bug</ref> and is referred to as "block dropping"<ref> Jeb has once said that the observer block's pulse "Allows tricking sticky pistons into dropping blocks"—https://www.reddit.com/r/Minecraft/comments/5c752g</ref> or sometimes "block spitting".

Block dropping only works for blocks that were being pushed by the sticky piston before its extension was canceled—if it wasn't pushing any, the sticky piston attempts to pull blocks as usual once it starts retracting.

With block dropping it's possible to push (but not pull) a waterlogged block without causing the water to disappear.<ref>Template:Bug</ref>

Limitations

Sticky pistons have the same limitations for pushing as normal pistons. These limitations also apply for pulling: when a sticky piston is unpowered but cannot pull a block, it retracts without doing so.

The table below lists which blocks can or cannot be pulled.

-==== Soft Inversion ====
-{{exclusive|bedrock|section=1}}
-{{IN|be}}, a unique mechanic known as "soft inversion" occurs when a sticky piston is "soft-powered" by redstone. A [[Minecraft:redstone torch]] attached to such a [[Minecraft:soft-powered]] sticky piston will be deactivated, deviating from the normal rule that requires a block to be "[[Minecraft:hard-powered]]" to deactivate an attached torch. This piston-specific behavior allows for circuit designs where the torch is turned off by a dust line running into the side of the sticky piston's block, a feature exclusive to this edition.

-Sticky pistons finish extending early and start retracting if they lose power before the extension process is over; most 2[[Minecraft:Tick#Game tick | game tick]] long pulses, some 3 game tick long pulses (when [[Minecraft:Piston#Start delay|start delay]] is present) and all pulses equal to or shorter than 1 game tick that pistons can react to allow this to happen. This causes a sticky piston to "drop" the blocks it's pushing, leaving them behind when it starts to retract. Also, the first out of the blocks that are being moved ends up in its final position as soon as the piston starts retracting.

-* When toggled between on and off rapidly with a gravity affected block (such as sand) above it, a sticky piston can eventually break the block, which can be picked up as a resource. However, gravel broken this way never drops flint.
-* If a sticky piston powered by a short pulse directly pushes a waterlogged block, the block remains waterlogged at its new position.
-* Carpet can be placed on the sticky piston extension block, and remains even if it is replaced with a solid block using {{cmd|setblock}}.
