[Server thread/WARN]: Skipping Entity with id

Discussion in 'Spigot Plugin Development' started by KuramaStone, Apr 27, 2017.

  1. So I've been creating custom entities lately and have come across this problem:
    Code (Text):
    [Server thread/WARN]: Skipping Entity with id HarvestGolem
    I have found several people with a similar problem however the recommended fix tends to be the method below.
    Code (Text):
        public void registerGolem(Class<? extends Entity> customClass, String name, int id) {
            try {
                List<Map<?, ?>> dataMap = new ArrayList<Map<?, ?>>();
                for (Field f : EntityTypes.class.getDeclaredFields()){
                    if (f.getType().getSimpleName().equals(Map.class.getSimpleName())){
                        dataMap.add((Map<?, ?>) f.get(null));
                if (dataMap.get(2).containsKey(id)){
                Method method = EntityTypes.class.getDeclaredMethod("a", Class.class, String.class, int.class);
                method.invoke(null, customClass, name, id);
            catch (Exception e) {

    The entity does not save with the world. When the chunk it is in is unloaded it gives the error Skipping Entity id. I have seen several people mentioning that it is a problem with registering. Is there anything wrong with my method of registering?

  2. Can you post the code line how you used this method?
    Which server version do you use as dependency?
  3. Ah, yes. I apologize for forgetting to add these details.
    Here is how I register the entities:
    Code (Text):
            registerGolem(HarvestGolem.class, "HarvestGolem", 54);
            registerGolem(SeekerGolem.class, "SeekerGolem", 54);
            registerGolem(GuardGolem.class, "GuardGolem", 54);
            registerGolem(MinerGolem.class, "MinerGolem", 54);
            registerGolem(BreederGolem.class, "BreederGolem", 54);
    And I am using 1.8.8 which uses: net.minecraft.server.v1_8_R3
  4. Ok, the reason is simple, you used the entityId 54 which is the id of a Zombie, as i can read, you are trying to use a golem ( IronGolem ) the Id of the entity is 99 and not 54 should solve your issue :)

    You can also simply get those informations by going into the EntityTypes nms class
  5. Not quite. The golem is a Zombie which is set to a baby.

    EDIT: Here is a screenshot of the Harvest Golem:
  6. Ok, so does anything appear in the console after executing those methods?
    Something like "ID is already registered:" or "Cannot register to reserved id:" or similar?
  7. I am not. You may check the log yourself if you wish:

  8. ok, so just asking for that, your entity seems to be spawned correctly? is there a new issue or what?
  9. EDIT: It seems part of my post was cut from my first post. Please look at it again
  10. I changed them to this:
    Code (Text):
        @SuppressWarnings({ "unchecked", "rawtypes" })
        public void registerGolem(Class<? extends Entity> clazz, String name, int id){
            try {
                //Remove the lines with // in front of them if you want to override default entities (You'd have to remove the default entity from the map first though).
                ((Map) getPrivateField("c", EntityTypes.class, null)).put(name, clazz);
                ((Map) getPrivateField("d", EntityTypes.class, null)).put(clazz, name);
                //((Map)getPrivateField("e", net.minecraft.server.v1_7_R4.EntityTypes.class, null)).put(Integer.valueOf(id), clazz);
                ((Map) getPrivateField("f", EntityTypes.class, null)).put(clazz, Integer.valueOf(id));
                //((Map)getPrivateField("g", net.minecraft.server.v1_7_R4.EntityTypes.class, null)).put(name, Integer.valueOf(id));
            catch (Exception e) {
        public Object getPrivateField(String fieldName, Class<? extends Object> clazz, Object object) {
            Field field;
            Object o = null;

                field = clazz.getDeclaredField(fieldName);


                o = field.get(object);
            catch(NoSuchFieldException e)
            catch(IllegalAccessException e)

            return o;
    However when the server attempted to load them again I received the same warning:
    Code (Text):
    [12:39:53] [Server thread/WARN]: Skipping Entity with id HarvestGolem
    [12:39:53] [Server thread/WARN]: Skipping Entity with id GuardGolem
    [12:39:53] [Server thread/WARN]: Skipping Entity with id SeekerGolem
    [12:39:53] [Server thread/WARN]: Skipping Entity with id MinerGolem
    [12:39:53] [Server thread/WARN]: Skipping Entity with id BreederGolem
  11. As a small line is already inside, check this:

    //Remove the lines with // in front of them if you want to override default entities (You'd have to remove the default entity from the map first though).

    So you may remove the // from "e" and "g" also update the nms path
  12. I don't want to override them and I may have to override entities at a later time, so I will leave them there as they do no harm. However just to ensure that there was no misunderstanding I did so. While I did not receive the warning the entity still did not appear from the saved chunk. However this may be because I did not override the default entity as I do not know how to do so. Could you explain it to me?
  13. Not really, because i haven't done something like you asked for but tryed to help out a bit sry :/
