lukas2005 · January 28, 2017

I have my weight system where on startup each item/block gets a weight value from config or creates defaults

now i need to attach some data to itemstack. Do i do this trought capablilities?

Choonster · January 28, 2017

You can do this by storing the data in the stack's compound tag or by attaching a capability to the stack.

Subscribe to

AttachCapabilitiesEvent.Item

and use

AttachCapabilitiesEvent#addCapability

to attach a capability provider to the

ItemStack

.

Once this PR is merged, you should subscribe to

AttachCapabilitiesEvent<ItemStack>

instead.
