Enemy follow player on planet

Hello everyone, I’m working on game like Mario Galaxy. I have a problem with “enemy follow script”.
The script works fine until enemy reaches equator of planet and then starts spinning crazy.

Here is my Enemy Follow Script:

var lookPos = GetComponent<AiBehavior>().targetNode.transform.position - transform.position;
lookPos.y = 0;
var rotation = Quaternion.LookRotation(lookPos);
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * 5f);

GetComponent<Rigidbody>().MovePosition(GetComponent<Rigidbody>().position +   transform.TransformDirection(moveAmount) * Time.fixedDeltaTime);

Scripts for Gravity:


public float gravity = -10;

    public void Attract(Transform body)
        Vector3 targetDirection = (body.position - transform.position).normalized;
        Vector3 bodyUp = body.up;

        body.rotation = Quaternion.FromToRotation(bodyUp, targetDirection) * body.rotation;
        body.GetComponent<Rigidbody>().AddForce(targetDirection * gravity);


Gravity body

public FauxGravityAttractor attractor;
private void PlanetGravityCalculation()
        attractor = GameObject.FindGameObjectWithTag("Attractor").GetComponent<FauxGravityAttractor>();
        GetComponent<Rigidbody>().constraints = RigidbodyConstraints.FreezeRotation;
        GetComponent<Rigidbody>().useGravity = false;
    private void PlanetGravityProces()

Any Ideas :)?

Well, you could write a better script… or you could flub it so your enemy is never on the equator, such as its start coordinate being an odd number and its coordinates increasing by 2 so it never touches the equator – or if its location is on the equator it increases by +1 in the current movement vector.
