Telepistons
by Tec
Telepistons changes how piston arms move on Fabric and Quilt, adding the telescopic arm animation from Bedrock Edition to Java.
What it does
The mod replaces the default piston arm motion with a telescopic extension, and offers an alternative squishy animation with optional steam particles. Each behaviour is switched on or off in the piston arm model file, through the squish and particles entries, so a resource pack author decides per model. The mod requires Fabric API to run and is published for Fabric and Quilt, with files for 1.16.5 – 26.3.
Because it is a client-side change, only the client needs it: players install it and servers run without it. The code is released under the CC0 1.0 Universal license and is open source, with its source code published publicly.
Three add-on resource packs ship with the mod. They add sticky piston sides, squishing bellows and scissors or springs. Pack developers build custom arm shapes that fit the vanilla piston head geometry and place those in their pack as normal.
Key features
Telescopic piston arms
The piston arm extends in a telescopic motion modeled on the Bedrock Edition animation.
Squishy animation option
A squish setting in the arm model file changes the arm to a squishier animation instead of the telescopic one.
Steam particles
A particles setting controls whether pistons emit steam particles while they move.
Sticky piston sides
An add-on resource pack gives pistons sticky sides that the arm model can use.
Squishing bellows and springs
Further add-on packs add squishing bellows and scissors or springs as alternative piston looks.

Use cases
Resource pack authoring
Pack developers shape piston arms around the vanilla head models and set the squish and particles entries in arm.json to choose the animation.
Bedrock-style pistons on Java
Players who want the telescopic arm animation from Bedrock Edition can get it on a Java client without changing any blocks.
Who it’s for: Players who want Bedrock-style piston animations on Java, and resource pack developers who build custom piston models.

This tiny mod adds the telescopic piston arm animation seen in Bedrock Edition to Java, as well as the option for a squishier alternative animation and particle emission. It's also compatible with the G4mespeed mod for smoother piston animations over all.
