hey guys i just wanna make simple script that an object will follow point using point's position of x and z, but when i try to play it its gonna to wrong direction not to the point.

Question

void Start () {

     float xpoint = point.transform.position.x;
     float zpoint = point.transform.position.z;
     float xme = this.transform.position.x;
     float zme = this.transform.position.z;
     Debug.Log(" point x: " + xpoint + " point z: " + zpoint + " me x: " + xme + " me z: " + zme);

 }
 
 // Update is called once per frame
 void Update () {
     if (xme <= xpoint)
         vectorx = 1 * speed;
     if (xme >= xpoint)
         vectorx = -1 * speed;
     if (zme <= zpoint)
         vectorz = 1 * speed;
     if (zme >= zpoint)
         vectorz = -1 * speed;


 }

 

 void FixedUpdate()
 {
     if (xme != xpoint)
         Debug.Log("hey pewds");
         transform.position += new Vector3(vectorx * Time.deltaTime, 0f, 0f);
     if (zme != zpoint)
         transform.position += new Vector3(0f, 0f, vectorz * Time.deltaTime);
 }

}

It would be faster, and more reliable to do something like this:

 public Vector3 TargetPoint;
 public float Speed;
 public float TargetDistance;
 
 private Vector3 m_MoveDirection;
 
 void Start () {
     m_MoveDirection = TargetPoint - transform.position;
     m_MoveDirection.Normalize();
 }
 
 void Update () {
     float CurrentDistance = Vector3.Distance (TargetPoint, transform.position);

     // If moving full speed for one frame would have the object overshoot, just move to the target
     if (CurrentDistance < Speed * Time.deltaTime) {
         transform.position = TargetPosition;

     // If we are further than our minimum distance to the target, move full speed towards it
     } else if (CurrentDistance > TargetDistance) {
         transform.Translate (m_MoveDirection * Speed * Time.deltaTime);
     }
 }
