NMS Cant change a zombie into a villager zombie

I'm trying to get a zombie villager but it always just spawns a normal villager :/
I tryed overriding 2 methods:

Code:

@Override
public boolean isVillager()
{
    return true;
}
   
@Override
public void setVillager(boolean flag)
{
    getDataWatcher().watch(13, Byte.valueOf((byte)(1)));
}

 

@NortherKnight And you are not using the Bukkit API why?

 

Did you try calling setVillager(true); on your zombie? Without overriding the methods

 

@NortherKnight
When the new entity is created you need to set the value in the datawatcher, because no external source will call setVillager() when the entity is spawned.

 

1. I tryed to set it as a Villager with the bukkit API still gives me only a normal villager

Code:

for(Entity e : loc.getChunk().getEntities())
{
    if(e.getType().equals(EntityType.ZOMBIE)
    {
        Zombie z = (Zombie) e;
        z.setVillager(true);
    }
}

And i tryed setting the difficulty to hard but still only a villager
2. I dont know what you mean by setting the date watcher when the entity spawns maybe this:

Code:

@Override
    public void a(EntityLiving entityliving)
    {
        super.a(entityliving);
       
         EntityInsentient entityinsentient = (EntityInsentient)entityliving;
         EntityZombie entityzombie = new EntityZombie(this.world);
         
         entityzombie.m(entityliving);
         this.world.kill(entityliving);
         entityzombie.prepare(this.world.E(new BlockPosition(entityzombie)), null);
         entityzombie.setVillager(true);
         if (entityliving.isBaby()) {
           entityzombie.setBaby(true);
         }
         entityzombie.k(entityinsentient.ce());
         if (entityinsentient.hasCustomName())
         {
           entityzombie.setCustomName(entityinsentient.getCustomName());
           entityzombie.setCustomNameVisible(entityinsentient.getCustomNameVisible());
         }
         this.world.addEntity(entityzombie, CreatureSpawnEvent.SpawnReason.INFECTION);
         this.world.a(null, 1016, new BlockPosition((int)this.locX, (int)this.locY, (int)this.locZ), 0);
       
    }
