The PlayerDestroyItem Event is fired whenever a player destroys an item.

You will need to cast the event in the function header as this class:
crafttweaker.event.PlayerDestroyItemEvent
You can, of course, also import the class before and use that name then.

PlayerDestroyItem Events implement the following interfaces and are able to call all of their methods/getters/setters as well:

• IPlayerEvent

The following information can be retrieved from the event:

ZenGetter	Return Type
ZenGetter player	Return Type IPlayer
ZenGetter originalItem	Return Type IItemStack
ZenGetter hand	Return Type string
