Hostile custom mob wont spawn since 1.9

Hey guys,

i have trouble spawning my Custom Skeleton, which made no problems in Minecraft 1.8.
The strange thing about this is, passive mobs work properly.

On spawning there happens nothing, no errors.

working CustomChicken: (removed unessessary code for debugging)

Code:

public class CustomChicken extends EntityChicken{
    public CustomChicken(org.bukkit.World world)
    {       
        super(((CraftWorld)world).getHandle());
    }
  
    public CustomChicken(World w)
    {
        super(w);
    }
}

not working CustomSkeleton:

Code:

public class CustomSkeleton extends EntitySkeleton{
     public CustomSkeleton(org.bukkit.World world)
    {       
      super(((CraftWorld)world).getHandle());
    }
  
    public CustomSkeleton(World w)
    {
        super(w);
    }

the EntityTypes enum:

Code:

public enum EntityTypes {

    CUSTOM_CHICKEN("Chicken", 93, CustomChicken.class),
    CUSTOM_SKELETON("Skeleton", 51, CustomSkeleton.class);

    EntityTypes(String name, int id, Class<? extends Entity> custom) {
        addToMaps(custom, name, id);
    }

    public static CustomChicken spawnEntity(Entity entity, Location loc) {
        entity.setLocation(loc.getX(), loc.getY(), loc.getZ(), loc.getYaw(), loc.getPitch());
        ((CraftWorld) loc.getWorld()).getHandle().addEntity(entity);
        return (CustomChicken) entity;
    }
   
//made it just like the Chicken one for debugging, normally its a bit different
    public static CustomSkeleton spawnEntitySkel(Entity entity, Location loc) {
        entity.setLocation(loc.getX(), loc.getY(), loc.getZ(), loc.getYaw(), loc.getPitch());
        ((CraftWorld) loc.getWorld()).getHandle().addEntity(entity);
        return (CustomSkeleton) entity;
    }
(... get fields etc...)

Every suggestion is greatly appreciated!

Edit: btw, i tried multiple EntityTypes: Chicken, Pig, Sheep, Villager are working, Skeleton, Creeper, Spider etc. dont. Thats why i think hostile mobs make problems.

 

@Lordloss

1. It looks like you're replacing all Skeletons with your custom entity. Is this what you want, are do you just want to be able to spawn your custom entities?
   
2. 93 (id for your chicken) is not taken for any other base minecraft entity. 51 Is already taken by EntitySkeleton. You may want to change "51" to "94".

 

93 is ID for chicken, 51 for skeleton, it must be them, other IDs force the MC client to crash

@Zombie_Striker
And yes, i want to only spawn them myself. And no they dont replace the normal entitys, it worked all the time before, just have issues after the 1.9 update. I had the Skeleton Pets working for about a year without any problems. :/

 

@Lordloss
Then most likely this is either a bug or that they modified/added a new way to spawn in hostile mobs. Since the packets for spawning almost all entities require the same packet, the problem is with the API.

 

@Zombie_Striker thats what i thought, i just hope that somebody can tell me whats wrong with it, im not the only one with custom mobs i also tried EntityMonster instead of Entity, without success.
But thanks for your help

 

@Lordloss When registering custom entities like that you need to replace them in the NMS maps for the entities, are you sure the maps are still the same? Maybe there is now something new there or something changed and that's why they don't work properly.

I don't have a 1.9 build so I can't see it for myself.

 

This is the rest of the class:

Klick (open) Klick (close)

Code:

    private static void addToMaps(Class clazz, String name, int id)
    {

        ((Map)getPrivateField("c", net.minecraft.server.v1_9_R1.EntityTypes.class, null)).put(name, clazz);
        ((Map)getPrivateField("d", net.minecraft.server.v1_9_R1.EntityTypes.class, null)).put(clazz, name);
        ((Map)getPrivateField("e", net.minecraft.server.v1_9_R1.EntityTypes.class, null)).put(Integer.valueOf(id), clazz);
        ((Map)getPrivateField("f", net.minecraft.server.v1_9_R1.EntityTypes.class, null)).put(clazz, Integer.valueOf(id));
        ((Map)getPrivateField("g", net.minecraft.server.v1_9_R1.EntityTypes.class, null)).put(name, Integer.valueOf(id));
    }
  
    public static Object getPrivateField(String fieldName, Class clazz, Object object)
    {
        Field field;
        Object o = null;
        try
        {
            field = clazz.getDeclaredField(fieldName);
            field.setAccessible(true);
            o = field.get(object);
        }
        catch(NoSuchFieldException e)
        {
            e.printStackTrace();
        }
        catch(IllegalAccessException e)
        {
            e.printStackTrace();
        }
        return o;
    }

If they made something different here, hopefully i would get an exception somewhere what is not the case. Again, please note that passive mobs are working.

 

Anybody who knows whats going on?
