Prevent villagers from walking

How do i prevent a villager from walking?
Example?

 

Replace the normal villager mob with a custom one, that doesn't move.
Edit: Can also surround them with blocks.

 

But how i do that?

 

You can use world edit to set invisible iron doors around them
//set irondoor:1

 

...or use a slowness potion?

 

just remove movement ai goal.

 

((CraftVillager)villager).getHandle().getAttributeInstance(GenericAttribute.d).setValue(0);
Sets their internal walking speed to 0.

 

So does a slowness potion.

 

Maybe he doesn't want a potion effect on it...

 

your'e right i don't want potion effect

 

Well it's probably easier than learning NMS (sure, you've given him the code now, but what happens if the obfuscation changes?), but whatever he wants to use I suppose.

 

What is wrong with it?:

Code:java

package me.Ricardo.VillagerSelection;
 
import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.craftbukkit.v1_7_R1.entity.CraftVillager;
import org.bukkit.entity.Villager;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;
 
/**

public class VillagerSelection extends JavaPlugin implements Listener {
 
    @Override
    public void onEnable() {
        System.out.println("[VillagerSelection] Has been enabled!");
        PluginManager pm = Bukkit.getServer().getPluginManager();
        pm.registerEvents(new VillagerSelection() ,this);
 
    }
 
    @Override
    public void onDisable() {
 
    }
 
    @EventHandler
    public void Villager(Villager v){
        Location loc = v.getTarget().getLocation();
        Villager mob = (Villager)loc.getWorld().spawn(loc, Villager.class);
        ((CraftVillager)mob).getHandle().setProfession(5);
 
        v.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 180067, 6776767));
        v.setMaximumNoDamageTicks(60000);
        Bukkit.broadcastMessage("Test");
        v.setCustomName("EcoCraft selector");
        v.setCustomNameVisible(true);
        v.setMaxHealth(1000.0);
        v.setCanPickupItems(false);
        v.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 244444444, 244444444));
        return;
 
    }
}
 

 

That's not something to listen to if you're just going to spawn the villagers that don't move... Put that spawning code in a method that spawns the villager (or edits one if one is supplied) in the onEnable(). Look over the Bukkit API, as it's clear that you don't have much experience in events.
