## Adding items

### Special fields
|
||||
|
||||
Items can have these fields:
|
||||
* `_mcl_generate_description(itemstack)`: Required for any items which manipulate their
|
||||
description in any way. This function takes an itemstack of its own type and must set
|
||||
the proper advanced description for this itemstack. If you don't do this, anvils will
|
||||
fail at properly restoring the description when their custom name gets cleared at an
|
||||
anvil.
|
||||
See `mcl_banners` for an example.
|
||||
|
||||
All nodes can have these fields:
|
||||
|
||||
* `_mcl_hardness`: Hardness of the block, ranges from 0 to infinity (represented by -1). Determines digging times. Default: 0
