Hello there,

 

I would like to spawn my new working mob (working when summoned) instead of a Cow entity. I've seen on other posts that the best way to do that is to create a new entity at the spawning event of a cow, and to remove the old cow.

 

I've tried this way (and some others) :

 @SubscribeEvent
        public static void onWorldJoin(final EntityJoinWorldEvent entityJoinWorldEvent) {
            Entity entity = entityJoinWorldEvent.getEntity();
            if (entity instanceof CowEntity) {
                NewCowEntity newCow = e.create(entity.world);
                newCow.setPosition(entity.getPosition().getX(), entity.getPosition().getY(), entity.getPosition().getZ());
                entity.remove();
            }
        }

 

It's not working at all, the original cow just disappears and the newCow never comes. I've tried to teleport to any entity of type new_co but no entity is found (the EntityType is found however).

 

How could I repair this behaviour please .
