Trying to get Box to follow NPC

Troubleshooting ai
1

Hey guys, so i have created an npc that randomly moves. I want to implement an aggro range so if you walk inside the range the npc walks towards you. So i made a cube and the cube is positioned perfectly when i first run the program and move if the npc moves, however the cube goes flying off the map and not relative to the npc.

My npc:
[java]
public class Ogre extends Node {
private BetterCharacterControl ogre;
private Box aggro;
private Geometry aggroRange;
}

public Ogre{
ogre = new BetterCharacterControl(1f, 10, 1f);

this.addControl(ogre);
}
[/java]

This is how the ogre moves:
[java]
movementTimer = new Timer();
movementTimer.schedule(new TimerTask() {
@Override
public void run() {
Random walk = new Random();
if (walk.nextInt(3) == 1) {
direction = walk.nextInt(8);
if (direction == 0) {
walkDirection.set(0, 0, walk.nextInt(5));
ogre.setWalkDirection(walkDirection.normalize().multLocal(movementSpeed));
}
if (direction == 1) {
walkDirection.set(0, 0, walk.nextInt(5) - 11);
ogre.setWalkDirection(walkDirection.normalize().multLocal(movementSpeed));
}
if (direction == 2) {
walkDirection.set(walk.nextInt(5) - 11, 0, walk.nextInt(5));
ogre.setWalkDirection(walkDirection.normalize().multLocal(movementSpeed));
}
if (direction == 3) {
walkDirection.set(walk.nextInt(5), 0, walk.nextInt(5) - 11);
ogre.setWalkDirection(walkDirection.normalize().multLocal(movementSpeed));
}

                if (direction == 4) {
                    walkDirection.set(walk.nextInt(5), 0, 0);
                    ogre.setWalkDirection(walkDirection.normalize().multLocal(movementSpeed));
                }
                if (direction == 5) {
                    walkDirection.set(walk.nextInt(5) - 11, 0, 0);
                    ogre.setWalkDirection(walkDirection.normalize().multLocal(movementSpeed));
                }
                if (direction == 6) {
                    walkDirection.set(walk.nextInt(5), 0, walk.nextInt(5));
                    ogre.setWalkDirection(walkDirection.normalize().multLocal(movementSpeed));
                }
                if (direction == 7) {
                    walkDirection.set(walk.nextInt(5) - 11, 0, walk.nextInt(5) - 11);
                    ogre.setWalkDirection(walkDirection.normalize().multLocal(movementSpeed));
                }
            } else {
                walkDirection.set(0, 0, 0);
                ogre.setWalkDirection(walkDirection.normalize().multLocal(movementSpeed));

            }

        }
    }, 0, 1000);

[/java]

I made the cube and in my update method:
[java]
ogre.aggroRange().move(ogre.getWalkDirection().normalize().multLocal(ogre.getMovementSpeed()));
[/java]

But like i said, the cube goes flying. It does stop when the ogre stops and moves when the ogre moves but where the ogre is.

How do you edit on this forum? Anyways my last sentence:
But like i said, the cube goes flying. It does stop when the ogre stops and moves when the ogre moves but not where the ogre is.

You may need to multiply the velocity by the elapsed time to get an offset. The argument to your update function should be an elapsed time. Try that.

Or copy the position from the ogre to the cube on each update. Or simply attach your cube to the ogre’s main node.
