I have an entity:

package com.DEBmods.modularships;

import net.minecraft.entity.Entity;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;

public class EntityShipBlock extends Entity{
public EntityShipControl controller;
public int Xoff;
public int Yoff;
public int Zoff;
public float rotationRoll;
public int counter = 0;

public EntityShipBlock(World par1World) {
	super(par1World);
}

public boolean canBePushed()
    {
        return false;
    }

@Override
protected void entityInit() {
}

@Override
protected void readEntityFromNBT(NBTTagCompound var1) {
}

@Override
protected void writeEntityToNBT(NBTTagCompound var1) {
}

//STUFF FOR onUpdate ONLY!!!
public void onUpdate() {
	//Updates rotation and position
	if (controller != null) {
		this.setRotation(this.controller.rotationYaw, this.controller.rotationPitch);
		this.rotationRoll = this.controller.rotationRoll;
		this.setPosition(controller.posX, controller.posY, controller.posY);
	}

	if (this.counter == 20) {
		System.out.println("X = " + this.Xoff + " Y = " + this.Yoff + " Z = " + this.Zoff);
	}

	//Updates counter
	if (this.counter >= 20) {
		this.counter = 0;
	}else {
		++this.counter;
	}
}
}

 

When I have one in the world, I get an output like:

X = -1 Y = 0 Z = 0

X = 0 Y = 0 Z = 0

(both lines at the same time) and any time I try to use offX, offY, or offZ they act like 0.

How would I go about doing that?

 

Looked up DataWatcher and find some examples out there.

 

I used it on one of my entities and it works like a charm.

Thanks, got it working!
