How to turn an enemy towards the player in Unity2D?

Question

Unity

I'm making a game on Unity2D with a top view, where you need to destroy the enemy base. Various robots (enemies) should interfere with me, but I stalled on creating AI. I did a patrol but couldn't implement the pursuit. I want the enemy to turn towards the player and walk forward and I don't know how to do it. Tried through LookAt, but the turn is too sharp. If through Qutarnion.Lerp, then the enemy is constantly rotated to the 0th value in Z, or rotated, but in all coordinates, although only Z is needed. So how do I rotate the enemy towards the player? Here is the code, do not judge strictly because I'm just starting.

public class EnemyAI : MonoBehaviour {

  public float speed;
  public float mSpeed;
  private float waitTime;
  public float StartWaitTime;

  float angle;
  public float value;
  public float mvalue;

  public Transform player;

  void Start()
  {
    waitTime = StartWaitTime;
  }


  	void Update() {

    if (waitTime <= 0)
    {
      value = Random.Range(0, 10);   
      mvalue = Random.Range(1, 4);   
      waitTime = StartWaitTime;   
 			RandomAngle();   
    }
 		else
    {
 			waitTime -= Time.deltaTime; //таймер
    }
  		if(Vector2.Distance(transform.position, player.transform.position) < 10f)
    {
      Quaternion Rot2 = Quaternion.Euler(0, 0, player.position.z);

      transform.rotation = Quaternion.Lerp(transform.rotation, Rot2, Time.deltaTime * speed); 
    }
 		else if (mvalue == 2)
    {
      transform.Translate(Vector2.left * mSpeed * Time.deltaTime);
    }
    else
    {
      Quaternion Rot = Quaternion.Euler(0, 0, angle);

      transform.rotation = Quaternion.Lerp(transform.rotation, Rot, Time.deltaTime * speed);
    }
  }

  void RandomAngle()
  {
    if (value == 1)
    {
      angle = 45;
    }
    if (value == 2)
    {
      angle = 90;
    }
    if (value == 3)
    {
      angle = -45;
    }
    if (value == 4)
    {
      angle = -90;
    }
    if (value == 5)
    {
      angle = 135;
    }
    if (value == 6)
    {
      angle = 180;
    }
    if (value == 7)
    {
      angle = -135;
    }
    if (value == 8)
    {
      angle = 0;
    }
  }
}

Answer 1

Hey ! You need to rotate on the y axis (probably ) try using lookat(your player) also to look up player position you need to use if(distans() player position , tansform.position)
You can also look at this ( https://youtu.be/S7- unUDLI6A ) yes, yes, this is advertising (no)

Answer 2

I recommend to look at this , suddenly it will help. (not advertising, dear administration)
