Fired every tick that a player is 'using' an item, see MCLivingEntityUseItemStartEvent for info.
Cancel the event, or set the duration or <= 0 to cause the player to stop using the item.
The event is cancelable.
If the event is canceled, the player will stop using the item.
The event does not have a result.
Importing the class
It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import at the very top of the file.
