Creating super classes for NMS entities

I created a superclass for a few entities that will share many characteristics that extends EntityCreature. I then created a subclass that I registered as a wither skeleton. When I spawn it in, it is a invisible thing. Anyone know why?

 

Dude, what do you expect us to tell you if we don't even know what you have coded?

 

superclass:

Code:

public class Thing extends EntityCreature{
public Thing(World world){
        super(((CraftWorld) world).getHandle());
        Set goalB = (Set) Reference.getPrivateField("b", PathfinderGoalSelector.class, goalSelector);
        Set goalC = (Set) Reference.getPrivateField("c", PathfinderGoalSelector.class, goalSelector);
        Set targetB = (Set) Reference.getPrivateField("b", PathfinderGoalSelector.class, targetSelector);
        Set targetC = (Set) Reference.getPrivateField("c", PathfinderGoalSelector.class, targetSelector);
        goalB.clear();
        goalC.clear();
        targetB.clear();
        targetC.clear();
        targetSelector.a(1, new PathfinderGoalHurtByTarget(this, true));
}
}

subclass:

Code:

public class Basic extends Thing{
public Basic(World world){
super(((CraftWorld)world).getHandle())
}
}

spawning it in (player = player that typed out command):

Code:

Basic basic = new Basic(player.getWorld());
                        ((CraftWorld) player.getWorld()).getHandle().addEntity(basic);
                        basic.setPosition(player.getLocation().getX(), player.getLocation().getY(), player.getLocation().getZ());
}

 

I'm probably wrong, but I think that's an issue in Bukkit itself. The fix I'm aware of is restarting your server or such.

 

You haven't registered the entity

 

@Drakonn I did, I just did not show it above. I know the registering works.
