Solved [NMS] Custom Entity is like invisible

Hey.
I want a custom villager, which is unpushable (by players) and they can't move.
So i created a class:

Code:java

package net.dori99xd.***.listener;
 
import java.lang.reflect.Method;
 
import net.minecraft.server.v1_7_R4.EntityVillager;
import net.minecraft.server.v1_7_R4.World;
 
import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.craftbukkit.v1_7_R4.CraftWorld;
import org.bukkit.event.entity.CreatureSpawnEvent.SpawnReason;
 
public class CustomEntityVillager extends EntityVillager {
 
public CustomEntityVillager(World world) {
super(world);
}
 
// Removed for testing..
/*
@Override
public void h() {
Bukkit.broadcastMessage("h");
super.h();
}
 
@Override
public void move(double a, double b, double c) {
Bukkit.broadcastMessage("mv");
super.move(a, b, c);
}
 
@Override
public void collide(Entity e) {
Bukkit.broadcastMessage("collide");
super.collide(e);
}
*/
 
public static void spawn(Location loc) {
try {
CustomEntityVillager v = new CustomEntityVillager(((CraftWorld) loc.getWorld()).getHandle());
//v.setPosition(location.getX(), location.getY(), location.getZ());
v.setLocation(loc.getX(), loc.getY(), loc.getZ(), 0, 0);
((CraftWorld)loc.getWorld()).getHandle().addEntity(v);
v.setInvisible(false);
// Don't care if setPostion or setLocation, also tried after spawning
System.out.println("spawned");
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
 
public static void spawnPatched(Location loc) {
try {
if(!patched)
patch();
CustomEntityVillager v2 = new CustomEntityVillager(((CraftWorld) loc.getWorld()).getHandle());
//v.setPosition(location.getX(), location.getY(), location.getZ());
v2.setLocation(loc.getX(), loc.getY(), loc.getZ(), 0, 0);
((CraftWorld) loc.getWorld()).getHandle().addEntity(v2);
v2.setInvisible(false);
// Don't care if setPostion or setLocation, also tried after spawning
System.out.println("spawned");
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
 
public static boolean patched = false;
public static void patch() {
try {
Method a = net.minecraft.server.v1_7_R4.EntityTypes.class.getDeclaredMethod("a", Class.class, String.class, int.class);
a.setAccessible(true);
a.invoke(a, CustomEntityVillager.class, "CustomVill", 12);
patched = true;
System.out.println("registered");
} catch (Exception e) {
System.err.println(e.getMessage());
patched = false;
}
}
}
 

Problem is, the villagers are "invisible". I know that they are spawned. The make sounds, but if i activate the hitboxes (F3+B) i dont see they. Why?

Before i forgot it: Using lastest Patched Spigot Build #1649 with Protocol Hack and CraftBukkit 1.7.10-R0.1.

Don't care if i use setPostion or setLocation. "spawn" also works without "register" entity (patch method).

Nobody that can help me?

 

Do you want some of my code?. I don't really know the way you do it but I have a nice way using nms

 

DuskFireHD Sure.

 

dori99xd 1 question how to you like paste like bits of code here?

Im writing up a small example for you now

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

dori99xd Have you registered the mob?
This is what I have
SORRY FOR SPOONFEED

Code:

package com.funergy.ss.CustomEntity;
 
import net.minecraft.server.v1_7_R4.EntityVillager;
import net.minecraft.server.v1_7_R4.World;
 
import org.bukkit.Location;
import org.bukkit.craftbukkit.v1_7_R4.CraftWorld;
import org.bukkit.craftbukkit.v1_7_R4.entity.CraftLivingEntity;
import org.bukkit.craftbukkit.v1_7_R4.entity.CraftVillager;
import org.bukkit.entity.Villager;
import org.bukkit.event.entity.CreatureSpawnEvent.SpawnReason;
import org.bukkit.util.Vector;
 
/**
* @author Funergy

*/
public class FrozenVillager extends EntityVillager{
   
    public FrozenVillager(World world) {
        super(world);
    }
   
    @Override
    public String t(){
        return "";
    }
 
   
    @Override
    public void move(double d0, double d1, double d2) {
        return;
    }
 
    @Override
    public void g(double x, double y, double z) {
        Vector vector = this.getBukkitEntity().getVelocity();
        super.g(vector.getX(), vector.getY(), vector.getZ());
    }
 
    public static Villager spawn(Location location) {
        World mcWorld = (World) ((CraftWorld) location.getWorld()).getHandle();
        final FrozenVillager customEntity = new FrozenVillager(
                mcWorld);
        customEntity.setLocation(location.getX(), location.getY(),
                location.getZ(), location.getYaw(), location.getPitch());
        ((CraftLivingEntity) customEntity.getBukkitEntity())
                .setRemoveWhenFarAway(false);
        mcWorld.addEntity(customEntity, SpawnReason.CUSTOM);
        return (CraftVillager) customEntity.getBukkitEntity();
    }
 
}

And this is to register the entity

Code:

public class NMSUtils {
    public void registerEntity(String name, int id, Class<? extends EntityInsentient> nmsClass, Class<? extends EntityInsentient> customClass) {
        try {
 
            /*
            * First, we make a list of all HashMap's in the EntityTypes class
            * by looping through all fields. I am using reflection here so we
            * have no problems later when minecraft changes the field's name.
            * By creating a list of these maps we can easily modify them later
            * on.
            */
            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));
                }
            }
 
            /*
            * since minecraft checks if an id has already been registered, we
            * have to remove the old entity class before we can register our
            * custom one
            *
            * map 0 is the map with names and map 2 is the map with ids
            */
            if (dataMaps.get(2).containsKey(id)) {
                dataMaps.get(0).remove(name);
                dataMaps.get(2).remove(id);
            }
 
            /*
            * now we call the method which adds the entity to the lists in the
            * EntityTypes class, now we are actually 'registering' our entity
            */
            Method method = EntityTypes.class.getDeclaredMethod("a", Class.class, String.class, int.class);
            method.setAccessible(true);
            method.invoke(null, customClass, name, id);
 
            /*
            * after doing the basic registering stuff , we have to register our
            * mob as to be the default for every biome. This can be done by

            * we can loop though all available biomes afterwards. Here, again,
            * I am using reflection so we have no problems later when minecraft
            * changes the fields name
            */
            for (Field f : BiomeBase.class.getDeclaredFields()) {
                if (f.getType().getSimpleName().equals(BiomeBase.class.getSimpleName())) {
                    if (f.get(null) != null) {
 
                        /*
                        * this peace of code is being called for every biome,

                        * changes every version)
                        */
                        for (Field list : BiomeBase.class.getDeclaredFields()) {
                            if (list.getType().getSimpleName().equals(List.class.getSimpleName())) {
                                list.setAccessible(true);
                                @SuppressWarnings("unchecked")

                                */
                                for (BiomeMeta meta : metaList) {
                                    Field clazz = BiomeMeta.class.getDeclaredFields()[0];
                                    if (clazz.get(meta).equals(nmsClass)) {
                                        clazz.set(meta, customClass);
                                    }
                                }
                            }
                        }
 
                    }
                }
            }
 
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

And put this in the onEnable

Code:

NMSUtils nms = new NMSUtils();
        nms.registerEntity("Villager", 120, EntityVillager.class, FrozenVillager.class);

 

OMG!!! Thanks dude! I think i registered wrong... Thanks!!!

 

That's it
