NMS More Range

How could I make a hostile mob able to acquire and track targets that are further than the default limit of 16 blocks?

 

Plugers11 There was a similar thread a while ago: https://forums.bukkit.org/threads/extending-a-hostile-mobs-awareness.71000/

 

2012 ? :F

I have question GameplayJDK
That : https://forums.bukkit.org/threads/tutorial-increasing-pathfinding-range-of-an-entity.177678/

Could work to get more range to go specific location?

 

Plugers11 Hmm... It's 1.6 code, possibly some classes and fields got renamed.. But it should do the thing
I don't know if this code is still working, it's from 2012 too :/

Code:java

private boolean livingEntityMoveTo(LivingEntity livingEntity, double x, double y, double z, float speed) {
return ((org.bukkit.craftbukkit.entity.CraftLivingEntity)livingEntity).getHandle().getNavigation().a(x, y, z, speed);
}

 

I know how to navigate mob ..
But if blocks range is < 16 then path is null

 

Plugers11
Possibly you can try to navigate the mob step by step.. calculate the next position within 16 blocks, then the next and than the next again..

 

GameplayJDK You don't have other idea?

 

Plugers11 I have ever been someone who trys to avoid working with nms too much because the resulting solutions are not very version persistent and cause a lot of updating work, so I'm not that familiar with the possibilities.. :/

 

Plugers11
Let me get back to you on this.

How to set to go on location ?
I have this:

But how do this for my creeper?

Code:

            }

    }
 
    public static class PathfinderGoalWalktoTile extends PathfinderGoal {
 
        public EntityInsentient entity;
        public PathEntity path;
 
        public PathfinderGoalWalktoTile(EntityInsentient entitycreature) {
            this.entity = entitycreature;
        }
 
        @Override
        public boolean a() {
       
                    boolean flag = this.entity.getNavigation().c();
                    this.entity.getNavigation().b(false);
                    this.path = this.entity.getNavigation().a(425 , 83, 402);
                    System.out.println(path);
                    this.entity.getNavigation().b(flag);
       
                    if (this.path != null) {
                        this.c();
                    }
           
            return this.path != null;
        }
 
        @Override
        public void c() {
            this.entity.getNavigation().a(this.path, 0.8D);
        }
    }
}

This can be for walk to location of mob ?

Code:

import net.minecraft.server.v1_7_R3.EntityInsentient;
import net.minecraft.server.v1_7_R3.Navigation;
import net.minecraft.server.v1_7_R3.PathEntity;
import net.minecraft.server.v1_7_R3.PathfinderGoal;
 
import org.bukkit.Location;
 
public class PathfinderGoalWalkToLoc extends PathfinderGoal
{
  private double speed;
 
  private EntityInsentient entity;
 
  private Location loc;
 
  private Navigation navigation;
 
  public PathfinderGoalWalkToLoc(EntityInsentient entity, Location loc, double speed)
  {
    this.entity = entity;
    this.loc = loc;
    this.navigation = this.entity.getNavigation();
    this.speed = speed;
  }
 
  public boolean a()
  {
    return true;
  }
 
  public void c()
  {
      PathEntity pathEntity = this.navigation.a(loc.getX(), loc.getY(), loc.getZ());
 
      this.navigation.a(pathEntity, speed);
  }
}
 

Code:

public CustomCreeper(net.minecraft.server.v1_7_R3.World world) {
        super(world);
        this.getAttributeInstance(GenericAttributes.a).setValue(48.0D);
        this.goalSelector.a(1, new PathfinderGoalWalkToLoc(this, getToLocation(), 2D));
    }

Ok i solved go to location but now i'm waiting for this range @zombiekiller753

I think it's done :3
I must do attribute

protected void aC() {
super.aC();
this.getAttributeInstance(GenericAttributes.b).setValue(100.0D);
}
