I am new to minecraft modding, and I want to make a event let player HP - 1 when player kill a animal, but I can't find a event which will fire when a animal being kill (I tried LivingDeathEvent but it donsn't work.)

	@SubscribeEvent	
	public void bloodMinxsOne(AttackEntityEvent event){
    	if(event.getTarget() instanceof AnimalEntity) {
            if (!event.getTarget().isAlive()) {
                PlayerEntity player = event.getPlayer();
                player.setHealth(1);
                if(!player.world.isRemote()){
                    String msg = TextFormatting.YELLOW + "you kill a animal";
                    player.sendMessage(new StringTextComponent(msg), player.getUniqueID());

                }
            }
        }
    }

I tried to use AttackEntityEvent but somehow it doesn't work

When the animal being kill, the isAlive will return null, I think that is the problem, is it have another method can detect target being kill?

How to check whether the DamageSource is cause by player? I want to use getDamageType method but I don't know how to check it is cause by player.

check if the Entity of the DamageSource is an instance of PlayerEntity

I have deal my problem, thanks you guys so much!
