Telepistons

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.

This mod requires the Fabric API to run!

Included are a few add-on Resource Packs which offer:

• Sticky Piston sides
• Squishing Bellows
• Scissors/Springs

(all of these support PBR)

Quick guide for Resource Pack developers:

• Model the piston arm around the vanilla piston_head models and put those in your pack as normal
• Split those models such that everything you want to not squish and to move at regular speed is in the piston_head_short models, and the arm parts are in a piston_arm model in the assets/telepistons/models/block/ directory
• Add the following to your piston_arm.json:

    "telepistons": {
    	"squish":"false",
    	"particles":"4",
    	"squishedScale": [ 1, 1, 0 ]
        }

• “squish” and “particles” determine whether the arm model gets squished and whether pistons emit steam particles respectively
• “squishedScale” determines the scale of the arm model once fully squished, i.e. the piston has fully retracted. Z points forward, so a vector of [1, 1, 0] will squish the arm just in that direction, while a vector of [2,2,0] will also make it get twice as wide and tall as it is squished.
