Solved Trying to Override EntityExperienceOrb

I have a class (OV_Orb) that extends the EntityExperienceOrb in which the method d(EntityHuman) is overridden. There is nothing in that method yet, except a broadcast, but if I get it to be called I know what to do. (Look if the Player is a Spectator and cancel it)
I didnt forget to register the new Entity and there are no errors in the console but the method is not called.

My class:

Code:

package tl.thewalls.overrides;

import java.lang.reflect.Method;

import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.craftbukkit.v1_8_R1.CraftWorld;
import org.bukkit.event.entity.CreatureSpawnEvent.SpawnReason;

import net.minecraft.server.v1_8_R1.EntityExperienceOrb;
import net.minecraft.server.v1_8_R1.EntityHuman;
import net.minecraft.server.v1_8_R1.EntityTypes;
import net.minecraft.server.v1_8_R1.World;

public class OV_Orb extends EntityExperienceOrb {

    public OV_Orb(World world) {
        super(world);
    }

    public static OV_Orb spawn(Location loc) {
        World w = ((CraftWorld) loc.getWorld()).getHandle();
        OV_Orb orb = new OV_Orb(w);
        orb.setPosition(loc.getX(), loc.getY(), loc.getZ());
        w.addEntity(orb, SpawnReason.CUSTOM);
        Bukkit.broadcastMessage("test1");
        return orb;
    }
   
    @Override
    public void d(EntityHuman e) {
        Bukkit.broadcastMessage("test2");
        return;
    }

    public static void registerEntity() {
        try {
            Method a = EntityTypes.class.getDeclaredMethod("a", Class.class, String.class, int.class);
            a.setAccessible(true);
            a.invoke(a, OV_Orb.class, "ExperienceOrb", 2);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
   
}

The method registerEntity() is called from my Main class and the Orb is spawned in the ExpBottleEvent. The broadcast "test1" appears in the chat.
Thanks in advance!

 

@Toastlawine
Is it only the d method that is not being called? If you also override another method, are you able to broadcast a message there?

 

I tried overriding s_() - didnt work either. In the source code of spigot 1.8 which i am using you can also clearly see that the method d() is responsible for giving the Player XP.
btw s_() is the moevent towards a Player

Update:
I got it to work with a different method of registrating the Custom Orb (I dont really understand how it works) and now it seems to be working but the Orb is invisible... I saw others having this problem but couldnt find a good solution for this. Im pretty sure that it has something to do with how I register it.

Now I got this:

Code:

public static void registerNonInsentientEntity(String name, int id, Class<? extends Entity> typeClass, Class<? extends Entity> customClass) {
        try {
            List<Map<?, ?>> dataMaps = new ArrayList<Map<?, ?>>();
            for (Field f : EntityTypes.class.getDeclaredFields()) {
                if (f.getType().getSimpleName().equals(Map.class.getSimpleName())) {
                    f.setAccessible(true);
                    dataMaps.add((Map<?, ?>) f.get(null));
                }
            }
            if (dataMaps.get(2).containsKey(id)) {
                dataMaps.get(0).remove(name);
                dataMaps.get(2).remove(id);
            }
            Method method = EntityTypes.class.getDeclaredMethod("a", Class.class, String.class, int.class);
            method.setAccessible(true);
            method.invoke(null, customClass, name, id);
        
            for (Field f : BiomeBase.class.getDeclaredFields()) {
                if (f.getType().getSimpleName().equals(BiomeBase.class.getSimpleName())) {
                    if (f.get(null) != null) {

                        for (Field list : BiomeBase.class.getDeclaredFields()) {
                            if (list.getType().getSimpleName().equals(List.class.getSimpleName())) {
                                list.setAccessible(true);
                                @SuppressWarnings("unchecked")
                                List<BiomeMeta> metaList = (List<BiomeMeta>) list.get(f.get(null));

                                for (BiomeMeta meta : metaList) {
                                    Field clazz = BiomeMeta.class.getDeclaredFields()[0];
                                    if (clazz.get(meta).equals(typeClass)) {
                                        clazz.set(meta, customClass);
                                    }
                                }
                            }
                        }

                    }
                }
            }
        
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

The broadcasts are now called but the orbs only appear when they merge.

UPDATE: It works! If someone wants to see the code please write me. Thank you very much even when you just thought about this.
