Solved [UNSOLVED] Entity walk to tile not working

Hey guys,

I am trying to let an entity move to a specific location, but it doesn't work.

Here's my code:

CustomEntityPig:

Code:java

package com.me.test;
 
import net.minecraft.server.v1_7_R2.*;
import org.bukkit.Location;
import org.bukkit.craftbukkit.v1_7_R2.util.UnsafeList;
 
import java.lang.reflect.Field;
 
public class CustomEntityPig extends EntityPig {
    public CustomEntityPig(World world, Location target) {
        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();
        }
 
        this.goalSelector.a(0, new PathFinderGoalWalkToTile(this, target));
        this.goalSelector.a(1, new PathfinderGoalFloat(this));
        this.goalSelector.a(2, new PathfinderGoalPassengerCarrotStick(this, 0.3F));
        this.goalSelector.a(3, new PathfinderGoalBreed(this, 1.0D));
        this.goalSelector.a(4, new PathfinderGoalTempt(this, 1.2D, Items.CARROT_STICK, false));
        this.goalSelector.a(5, new PathfinderGoalTempt(this, 1.2D, Items.CARROT, false));
        this.goalSelector.a(6, new PathfinderGoalLookAtPlayer(this, EntityHuman.class, 6.0F));
        this.goalSelector.a(7, new PathfinderGoalMeleeAttack(this, EntityHuman.class, 6.0F, true));
    }
}
 

PathfinderWalkToTile:

Code:java

package com.me.test;
 
import net.minecraft.server.v1_7_R2.EntityCreature;
import net.minecraft.server.v1_7_R2.PathfinderGoal;
import org.bukkit.Location;
 
public class PathFinderGoalWalkToTile extends PathfinderGoal
{
    private EntityCreature entitycreature;
 
    private double x = 0;
    private double y = 100;
    private double z = 100;
 
    public PathFinderGoalWalkToTile(EntityCreature entitycreature, Location target)
    {
        this.entitycreature = entitycreature;
        this.x = target.getX();
        this.y = target.getY();
        this.z = target.getZ();
    }
 
 
    public boolean a()
    {
        return true;
    }
 
    public void c()
    {
        this.entitycreature.getNavigation().a(x, y, z, 1);
    }
}

Spawn command:

Code:java

    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
    {
        Player player = (Player) sender;
 
        if(cmd.getName().equalsIgnoreCase("test"))
        {
            Location loc = player.getLocation();
 
            CustomEntityPig pig = new CustomEntityPig(((CraftWorld)player.getWorld()).getHandle(), new Location(player.getWorld(), 100, 100, 100));
            pig.setLocation(loc.getX(), loc.getY(), loc.getZ(), 1, 1);
            ((CraftWorld)player.getWorld()).getHandle().addEntity(pig);
        }
 
        return true;
    }

So it spawns the entity just fine, it just does everything right except the PathFinderWalkToTile.

Anyone?

nms can be a bitch. Make sure you got the correct methods. Have you double checked with the nms code, and not just copied of a tutorial? Got a stacktrace we can see aswell?

 

Mathias Eklund There is no error. And yes I have double checked the code.

I tried doing this:

Code:java

System.out.println(this.entitycreature.getNavigation().a(loc.getX(), loc.getY(), loc.getZ()));

So now I know the problem, it's always null for some reason. I tried using reflections to make the l() method which returns a boolean true, but that didn't work either.
