Check if all zombies dead?

Hello, I am trying to see if all my spawned zombies are dead. What is the best way to do that? Basically the goal is to kill them all so I'm trying to check if they're all dead. I do already have a listener set up. This is how I'm spawning them:

Code:java

while (i <= 10) {
Entity zombie = world.spawnEntity(to, EntityType.PIG_ZOMBIE);
((Creature) zombie).setTarget((LivingEntity) chicken);
areaRadius = 15; //Or any radius you want
minRadius = 10; // This would give me a radius between 500 and 1000
t = Math.random() * Math.PI;
radius = Math.random()*(areaRadius - minRadius) + minRadius;
x = Math.cos(t) * radius;
y = Math.sin(t) * radius;
z = Math.cos(t) * radius;
i++;
}

 

Add the zombies' IDs to a list. Listen to EntityDeathEvent, and if the entity's ID is in your list, remove it from the list and then check if the list is empty.

 

Thanks for the reply. What type should the list be though? Entity?

EDIT: I'm trying it with a string list. However, how would I find the index of the entity id in the list?

It would be a string list because you're using their ID. You wouldn't need to get the index for this solution, just use the contains() and remove() methods.

 

*int

Oh yeah, it would probably be int. I was thinking of player names.

 

adam753 how would you add the zombie to a list

 

Wantsome909 ArrayList<Integer> zombies = new ArrayList<Integer>();

 

Wantsome909
zombies.add(zombie.getUniqueId);

I think it should be getEntityId() but I'm nor sure what the difference is...
