Make mobs stationary

Hey bukkit,

So, I am working on a plugin that involves mobs. However, I am having a problem making them stationary (so players can't push them) I have tried using remoteenitites, but it is out of date. Are there any others that I can use to use the NMS code? Thanks everyone for reading!

Give them slowness 10 or above.

 

@Dsi_Mario Yea, but its kinda buggy looking. With that you can still move it then it gets tp'd back. I was looking for something more along the lines of you can't move it at all.

 

You can use the NMS: http://bukkit.org/threads/nms-tutorial-how-to-override-default-minecraft-mobs.216788/
It can be hard to learn but then its easy :3

@Leo38638 Man, that is kinda confusing. Is there away to do it without NMS? Other than what @Dsi_Mario said?

 

I would Use NMS.

 

I have used NMS before. I can't think of any way other than NMS to easly change the behavour of mobs.

 

@Antybarrel Can you help me on the thread? That way if other people are stuck, they can use this

 

@glasseater sure I'm free now if u still need help. How far you got?

 

@Antybarrel Well, not far I was about to resort to adding a potion effect but you can see the particles. Any ideas?
Thanks!

 

@glasseater You still want to use NMS or do you wan't to scratch that and just go down the potion effect route?

 

@Antybarrel I mean, I think I would prefer NMS for better results

 

@glasseater Well the guide linked above (http://bukkit.org/threads/nms-tutorial-how-to-override-default-minecraft-mobs.216788/) really does give a good insight into what it involes. First thing you're going to want to do is take the class 'CustomEntityType' straight from that page and put it into your plugin. You may not understand a lot of what is in there but don't worry someone has done all that for you.

 

@Antybarrel Ok, so I did that and I should change the Zombie to a villager?

 

2 Great ways!

Without NMS:
Make it ride a WitherSkull
NMS:
Speed.

 

@ChipDev What do you mean, sorry

 

@glasseater ^^^

Yea you do, the first "Zombie" you change to villager quite simple the id 54 needs to be changed to the
villager id which is 120

Code:

ZOMBIE("Zombie", 54, EntityType.ZOMBIE, EntityZombie.class, CustomEntityZombie.class);

VILLAGER("Villager", 120, EntityType.VILLAGER, EntityVillager.class, CustomEntityVillager.class);

After this you now need to make your 'CustomEntityVillager.class'

 

@Antybarrel Would I use the CustomEntityZombie class?

 

@glasseater No, unless you want to customise the zombie too. You can also delete the ZOMBIE line as well if you havn't done already. All you need to do is make a blank class name CustomEntityVillager.class.

 

@Antybarrel No luck :/

 

@glasseater Have you got your blank CustomEntityVillager.class open.

Code:

public class CustomEntityVillager extends EntityVillager {

    public CustomEntityVillager(World world) {
    super(world);

    try {
        Field bField = PathfinderGoalSelector.class.getDeclaredField("b");
        bField.setAccessible(true);
        Field cField = PathfinderGoalSelector.class.getDeclaredField("c");
        cField.setAccessible(true);
        bField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
        bField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
        cField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
        cField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
        } catch (Exception exc) {
        exc.printStackTrace();
        }


    }

}

Oh make sure you have
import java.lang.reflect.Field;
Imported



EDIT: I forgot! Also you will need to register and unregister these mobs in your onEnable and onDisable

Code:

public void onEnable(){
   
         CustomEntityType.registerEntities();
       
    }
   
    public void onDisable(){
        CustomEntityType.unregisterEntities();
        // Very important make sure you unregister
    }

 

@Antybarrel
Still no luck these are a few of the errors I get. http://gyazo.com/64b5a2e90eba206109818d6eca1a552c

 

@glasseater Can I see the whole class?

Make sure these are imported.

Code:

import java.lang.reflect.Field;
import org.bukkit.craftbukkit.v1_7_R3.util.UnsafeList;
import net.minecraft.server.v1_7_R3.EntityVillager;
import net.minecraft.server.v1_7_R3.PathfinderGoalSelector;
import net.minecraft.server.v1_7_R3.World;

The imports can vary depending on what verison of craftbukkit you are using.

 

@Antybarrel

Code:

import java.lang.reflect.Field;

import org.bukkit.craftbukkit.v1_7_R3.util.UnsafeList;
import net.minecraft.server.v1_7_R3.EntityVillager;
import net.minecraft.server.v1_7_R3.PathfinderGoalSelector;
import net.minecraft.server.v1_7_R3.World;

import org.bukkit.World;
import org.bukkit.craftbukkit.v1_7_R1.util.UnsafeList;

public class CustomEntityVillager {


public CustomEntityVillager(World world) {
super(world);

try {
    Field bField = PathfinderGoalSelector.class.getDeclaredField("b");
    bField.setAccessible(true);
    Field cField = PathfinderGoalSelector.class.getDeclaredField("c");
    cField.setAccessible(true);
    bField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
    bField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
    cField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
    cField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
    } catch (Exception exc) {
    exc.printStackTrace();
    }


}

}

 

@glasseater You might be getting errors if you havn't Referenced the Craftbukkit also it looks like your using v1.7_R1 so you will have to change that verison on the imports.

Try this:

Code:

import java.lang.reflect.Field;

import org.bukkit.craftbukkit.v1_7_R1.util.UnsafeList;
import net.minecraft.server.v1_7_R1.EntityVillager;
import net.minecraft.server.v1_7_R1.PathfinderGoalSelector;
import net.minecraft.server.v1_7_R1.World;



public class CustomEntityVillager extends EntityVillager {

    public CustomEntityVillager(World world) {
    super(world);
   
    try {
        Field bField = PathfinderGoalSelector.class.getDeclaredField("b");
        bField.setAccessible(true);
        Field cField = PathfinderGoalSelector.class.getDeclaredField("c");
        cField.setAccessible(true);
        bField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
        bField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
        cField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
        cField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
        } catch (Exception exc) {
        exc.printStackTrace();
        }
   

    }
   
   

   
   
   
}

 

@Antybarrel Ok, I changed the imports. What do you mean "Reference Craftbukkit"?

 

@glasseater What IDE do you use?

 

@Antybarrel Eclipse

 

@glasseater Ok, if you right click your project, click properties, java build path.
Then Click libraries and if you already have it there it should say something like craftbukkit-1.7 etc

If not, You need to click add external jars then locate your craftbukkit.jar server that you are running.

 

@Antybarrel Yea, I already had craftbukkit there.
