Item Capabilities (1.16.5)

[Babelincoln1809]

Hello, I'm trying to better understand capabilities and how they work. I see a lot of examples/tutorials for entities and tile entities but not much for itemstacks, at least from what I could find. I'm trying to make an itemstack store an entity and a sound event for my own item, I dunno if I can possibly do that any other way as well. Any where I could look as an example/guide, or just an explanation?

it's the same, the only thing that changes is you attach the capability to and ItemStack and not to an Entity/BlockEntity

Alright, so how would I go about about attaching it to my own item? There's an initcapabilites method in the item class that the bucket uses, so I'm assuming that? And how would I set things like soundevent and entity in the item class?

I attached it to the item by using that event, it keeps crashing though saying that the sound event could be null. I did add a null check, but it still crashes. I'm a bit stumped on what to do

okay first of all, you don't need an IStorage, just return and empty CompoundNBT, you should because the error occurs there
inside of getCapability you need to check if it is your Capability
and your serializeNBT and deserializeNBT methods in your StaffProvider are broken,
add a serializeNBT & deserializeNBT to your DefaultStaffCapability and call them inside the method

why did you add two providers to the ItemStack?
you should also create a git repo because it is terrible to look at many classes when using pastebin
