- Right-click a powered, extended piston to cycle its extension length between 1, 2, and 3 blocks (an overlay message confirms the new length)
- Works on both regular and sticky pistons: sticky pistons pull the block back when retracting, and re-adjusting length while extended repositions any stuck block accordingly
- Adds an intermediate Piston Shaft block that fills the gap between the piston base and its head when extended more than 1 block; it behaves as an inert, unmovable connector and is removed automatically when the piston retracts
- Extension length is persisted per-piston (survives world reloads) via a
SavedData-backed store - Respects vanilla pushable/block-count rules when extending: a push that would fail on a vanilla piston (unmovable blocks, too many blocks in the chain) still fails here
Learning It
Right-clicking a piston cycles how far it pushes, and there is nothing to find: no recipe, no item, no particle. The block looks identical at every setting, so the only way anyone learns this is being told.
With village-quests installed, a mason or toolsmith wants a gate that actually opens and asks you to set a piston to a reach of three. One is what a piston already does and two could be an accident; three is unmistakably somebody who knows.
Optional and guarded: without village-quests the mod behaves exactly as before.
Pandorical
Piston Extension runs server-side, and Pandorical is a hard dependency (fabric.mod.json): the server will not load this mod without it. The Piston Shaft is registered as a Pandorical content block and its assets are synced from this jar.
Clients are the optional half. A player on a Pandorical client sees the shaft; because it is a real registered block, a vanilla client cannot render it and cannot receive chunks containing one. Extension length, sticky behaviour and the push rules are all server-side and unaffected.
