Getting held item's NBT information

[Coder]

Hi,

 

Is it possible to get the items NBT information while holding it? 

(when hovering above items there is a text that says how many tags are there inside the item, but I would like to know what's inside those tags)

ItemStack has a number of methods related to this. Did you look at the type hierarchy to see the list of methods? You can check if it hasTagCompound(), and there is getTagCompound() and a bunch of other related methods.

I would recommend taking a look at how Actually Additions does it in the item Tooltip event. They did it really well
