My EnemyAI is flying towards me

can someone look at my code and tell me what i did wrong? because i really don't understand what i did wrong. My enemy should be walking on the ground but instead it's hovering in the air don't really know why.

here is my code:

i hope someone can help me!

using UnityEngine; using System.Collections;

public class EnemyAI : MonoBehaviour { public Transform target; public int moveSpeed; public int rotationSpeed;

 private Transform myTransform;

 void Awake() {
     myTransform = transform;
 }


 // Use this for initialization
 void Start () {
     GameObject go = GameObject.FindGameObjectWithTag ("Player");

     target = go.transform;
 
 }
 
 // Update is called once per frame
 void Update () {
     Debug.DrawLine (target.position, myTransform.position, Color.yellow);


     // look at target
     myTransform.rotation = Quaternion.Slerp (myTransform.rotation, Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed * Time.deltaTime);
 
     // move towards target
     myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;

 }

}
