From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Phoenix616 Date: Tue, 21 Aug 2018 01:39:35 +0100 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. == AT == public net.minecraft.world.entity.LivingEntity getDeathSound()Lnet/minecraft/sounds/SoundEvent;
