Thats a good idea! I'll consider it

i think the actual datapack is inside the folder u downloaded

Minecraft datapacks don't allow fully custom items in the game without mods, so we have to use vanilla items and modify it from there



If u want more detail on this:

In Java coding language, every item is calculated using a "Registry Handler", I know a bit about this since I have made actual mods before



Every item gets coded through a "model", "texture", and "abilities" such as using an ender pearl



In a datapack, if u try and make a FULLY custom item, the game wouldnt be able to calculate it unless ur also using a mod with that item at that time

I hope this was useful.
