This event is fired to determine if an animal is going to be tamed. If canceled, the tame does not succeed. Otherwise, it simply serves as a notification of the tame taking place.

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