Set Attack Damage and Speed based on NBT

[drok0920]

Hello again,

I have a custom tool that has an nbt tag on it.  I would like to map this nbt tag's value to damage and swing speed.  I know how to map my value i just dont know where i can set the damage and speed.  I thought i could use getItemAttributeModifiers but im not aware of a way to get the nbt data in that method.  I hope this makes sense.  Please point me to a method that can do what i need.

When the item stack is created you need to set the attribute modifiers (attack damage and attack speed).

Anytime you update the NBT to have a different value, you would have to update the attributes as well.

Override Item#getAttributeModifiers, the ItemStack-sensitive version of Item#getItemAttributeModifiers. It has an ItemStack argument that you can access the NBT of.

You can hide the attribute modifiers from the tooltip completely by setting the "HideFlags" key of the ItemStack's compound tag to a number with bit 2 set to 1 (e.g. 2).

 

You can also subscribe to ItemTooltipEvent and modify the list of tooltip lines as you want.

Do i use setInteger or setShort?  By what im reading on the wiki its a value 1-63 so i would assume its a short because an integer would hold way to many values.

ItemStack#getTooltip checks for its existence using the type ID 99, which is "any numeric". This means you can use any numeric data type for the tag, including integer and short.
