Minecraft:Sticky Piston

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.

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.

Trivia

• Jeb considers inertia to make sense as an interpretetion of why can sticky pistons drop blocks Template:In.<ref>https://reddit.com/r/Minecraft/comments/5c752g/help_us_decide_should_observers_update_at_1_or_2/d9zmv4l/?context=3#d9zmv4l</ref>
