The EntityLivingDeath event is fired whenever an Entity is about to die.
It can be canceled to let the entity live.

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

EntityLivingDeathEvent implements the following interfaces and are able to call all of their methods/getters/setters as well:

• ILivingEvent
• IEventCancelable
