Despawn specific animal

Hey,

I searched 1 hour for this but didn't find anything:/
So I spawned an animal, lets call it Charles. Now I wanne despawn him when someone leftclicks with wheat. The event stuff is no problem, onliest problem is that I have no idea how to remove Charles again.
Another dev gave me the tip to try world.getLivingEntities, if that helps^^
Thx for your reply!

If the entity is a per-player thing, save their UUIDs in a map.

If there's just one, save its UUID. If there are many, save their UUIDs in a set.

Alternatively, tag them with metadata.

If you store Charles (or its UUID) anywhere like a HashMap, you can fetch him back and call Entity#remove().

If not, use the World#getLivingEntities (or getLivingEntitiesByClass to be specific) to loop through the entities in that world, check if the entity is Charles (e.g. by comparing custom name), then again call Entity#remove().

edit: ninja'd.

Sorry, could you give me an example?

Code:java

 
// If there's one Charles
UUID charlesUniqueId = null;
 
// If there are a lots of Charles
Set<UUID> charlesUniqueIds = new Set<UUID>();
 

Just simply instantiate them:

Code:java

 
charlesUniqueId = <charles>.getUniqueId();
 
// or
 
charlesUniqueIds.add(<charles>.getUniqueId());
 

To remove them:

Code:java

 
for (Entity entity : Bukkit.getWorld("world").getLivingEntities()) {
    if (entity.getUniqueId().equals(charlesUniqueId)) {
        entity.remove();
        break;
    }
 
    // or
    if (charlesUniqueIds.contains(entity.getUniqueId()) {
        entity.remove();
        break;
    }
}
