And as you can see that enemy is attacking from different height. And 2nd problem is that he is floating. he have rigidbody how can i stop him from floating…
Also here is my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemyChase : MonoBehaviour {
	
	public Transform player;
	static Animator anim;

	void Start () {
		anim = GetComponent<Animator> ();
	}
	
	// Update is called once per frame
	void Update () {
		if (Vector3.Distance (player.position, this.transform.position) < 10) {
			
			Vector3 direction = player.position - this.transform.position;
			direction.y = 0;

			this.transform.rotation = Quaternion.Slerp (this.transform.rotation, Quaternion.LookRotation (direction), 0.1f);
			anim.SetBool ("isIdle", false);
			if (direction.magnitude > 3) {
				this.transform.Translate (0, 0, 0.05f);
				anim.SetBool ("isWalking", true);
				anim.SetBool ("isAttacking", false);
			} else {
				anim.SetBool ("isAttacking", true);
				anim.SetBool ("isWalking", false);
			}
			

		} else {
			anim.SetBool ("isIdle", true);
			anim.SetBool ("isWalking", false);
			anim.SetBool ("isAttacking", false);

		}
	}
}

He can shoot when you are above because you are not checking about it. You are actually discarding the y value. So even though you are 10 or 200m above, your enemy “sees” your player just next and will aim at him.

You would have to add a altitude check as well as a vision check.

Use a linecast between the enemy and the player so it can check whether it is seeing it or not.

Then if it can see it, check the y values.

if(Mathf.Abs(enemy.transform.y - player.transform.y) > 2f){ // He is above or below}

So as pseudo code you get:

void Udpate()
{
    if (distance > maxDistance) return;
    if(LinecastSuccess == false) return;
    if(AltitudeCheck > maxAltitudeDifference) return;
    Shoot();
}

The flying problem is because you are moving the enemy with transform. When a NPC has Rigidbody or CharacterController, if you use transform, that won’t do.
Try the following to begin with:

Hi… that check didn’t even worked… my enemy still can hit me from 10 meters above. :frowning:
