It's Okay to be Shelfish!

If you've been excitedly waiting the upcoming shelves, or if you are unable to update to newer versions, this is for you! This is my attempt to bring the new shelves early, completely server-side, powered by Filament.

How to Use

This mod requires Filament and Polymer to function, both of which are only required server-side.

For the pack's resources to function correctly, you will also need to set "enabled": false to true under /config/polymer/auto-host.json.

If you are having problems with placing/breaking sounds (1.21.5+), you can also set "always_handle_vanilla_block_sounds": false to true under /config/polymer/sound-patch.json.

Features & Incapabilities

Though this datapack currently implements the display functionality of the new shelf block, it does not yet implement the redstone locking or hotbar switching features that have been showcased in snapshots.
