Subject: [PATCH] Improve death events
|
|
|
|
This adds the ability to cancel the death events and to modify the sound
|
|
an entity makes when dying. (In cases were no sound should it will be
|
|
called with shouldPlaySound set to false allowing unsilencing of silent
|
|
entities)
|
|
|
|
It makes handling of entity deaths a lot nicer as you no longer need
|
|
to listen on the damage event and calculate if the entity dies yourself
|
|
to cancel the death which has the benefit of also receiving the dropped
|
|
items and experience which is otherwise only properly possible by using
|
|
internal code.
|
|
|
|
TODO 1.17: this needs to be checked (actually get off your lazy ass and cancel the events) for the following entities,
|
|
maybe more (please check patch overrides for drops for more):
|
|
- players, armor stands, foxes, chested donkeys/llamas
