This event is fired when an entity dies and drops experience, allowing for the amount of experience to be modified. Alternately, the event can be canceled to prevent experience from being dropped.

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

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

• IEventCancelable
• ILivingEvent

The following information can be retrieved/set during the event:

ZenGetter	ZenSetter	类型
ZenGetter player	ZenSetter ​	类型 IPlayer
ZenGetter droppedExperience	ZenSetter droppedExperience	类型 int
ZenGetter originalExperience	ZenSetter ​	类型 int

originalExperience contains the original Vanilla amount of experience. It is possible that droppedExperience when this event is fired has already been modified.
