Replace Elytra with Max HP

GAMEPLAY:

Every Elytra in an item frame will be replaced by a Bottled Heart when the Datapack is first activated. Any loaded in Elytras after the activation will also be replaced. Elytras put into an item fram AFTER the activation will not be replaced.

Currently 20 Hearts is the max.

Currently there is no method to subtract or transfer Hearts. (But if you are interested in that, I stole a lot of this from the Lifesteal Datapack, which does have those features.

HOW IT WORKS:

Every tick this datapack checks for item frames without a certain custom tag.

If a frame is found, and it has an Elytra, that Elytra is replaced with custom item and then tagged with the custom tag.

The custom item is a Regeneration potion with an item model set to a custom item from a resource pack, with some custom data, and other aethetic changes.

The custom item model is the "Bottled Heart" png, which is part of the resource pack.

Drinking a potion with the custom data of a Bottled Heart give you an acheivement, which activates a command to increase you Max Health by 1, and then revokes the acheivement.

Thank you to the Lifesteal and Elootra projects for the inspiration and code that I used as a foundation.

Other Notes:

• This is my first modirinth project so if something is off or different, thats why.
• This was made for version 1.21.8 and I dont plan on backporting it, but may keep up with future versions as needed.
• If you use this please feel free to let me know if you liked it. I made it because I think the Elytra is OP and makes the game less fun, so I figured Max HP is OP but hopefullly still keeps the game fun. Use it however you like!
