Showcase Standalone Revival - Source code on Bukkit

Showcase Standalone was last updated Sept 1, 2019 https://dev.bukkit.org/projects/scs

Unfortunately doesn't work for 1.16 as it console errors when creating a display. Source code is available on the page if someone could fix the errors.

I am looking for a replica that allows setting hovering items on a slab, that is protected by the player who created it/can add friends. OP can remove.

Various plugins like ItemShow, ItemFloat do not work. I have tested many already. I am not using Holographic Displays because the permissions do not allow for Item only commands.

Minecraft version: 1.16.2

Suggested name: Showcase Reloaded

What I want: Like the original Showcase plugin, like for like, or source code updated but only for item display, not buying or selling. You type a command to create a display, then right click the slab you want to set it to and the item floats dead center of the slab.

Example: /scs display feather - then prompts to right click slab to set display, right click, then the feather shows floating, and prompts that display was successfully created. Can not be broken by other players unless admin perm or added to edit by owner.

Ideas for commands:
/scs display <item>
/scs remove
/scs member add:remove name

Ideas for permissions:
scs.display - allows creation of displays
scs.remove - removes your own displays
scs.member.add - add someone who can edit your display
scs.member.remove - remove member
scs.admin - Can remove other players displays

When I'd like it by: Whenever possible.

 

I'm aware,

I've already tried to reach out, so now I'm requesting assistance here. I'm hoping to look for a more better solution that won't break every update.

 

This is the error you get when trying to display an item:
