How to make Enemy Shoot in Player Direction

In this article we will make the enemies shoot at the player. We start off with the pseudocode. There are 3 parts that need to be done. The enemy projectile prefab creation, enemy script fire feature, enemy projectile script.
(We changed up the player laser and created a new enemy projectile)

Enemy Projectile Creation

Create a prefab with a a sprite
Add Component: Rigidbody2D
Add Component: Collider 2D adjust when necessary
Is Trigger checked
Gravity Scale set to zero
Add Component: Script

We chose a round projectile so we can move it in any direction looking good.

Enemy Script

Enemy fires every x seconds
handle to enemyshot prefab
fire coroutine
while enemy is alive
instantiate enemyshot
wait x sec

IEnumerator FireRoutine()
    {
        while (_isAlive)
        {
            yield return new WaitForSeconds(_fireInterval);
            Instantiate(_enemyShot, transform.position + _offset, Quaternion.identity);
        }
    }

Enemy Projectile Script

Enemy laser move to player

handle to player
findobject of type
set player position as target
target minus own position = direction
normalize direction
(When normalized, a vector keeps the same direction but its length is 1.0.)

Vector3.Normalize

move enemy projectile in the calculated direction
destroy enemy projectile after X seconds

private GameObject _player;
private Vector3 _targetPlayer;
[SerializeField] private float _speed = 2f;
private Vector3 _direction; 

// Start is called before the first frame update
    void Start()
    {
        _player = GameObject.Find("Player");
        //null check into get current target location
        if (_player != null)
        {
            _targetPlayer = _player.transform.position;
        }
        else
        {
            Debug.LogError("EnemyShot.player is NULL");
        }
        //calculate direction to move (normalized scales values of vector to be max 1)
        _direction = (_targetPlayer - transform.position).normalized * _speed;

        Destroy(gameObject, 10f);
    }

// Update is called once per frame
    void Update()
    {
        transform.Translate(_direction * Time.deltaTime);
    }

Enemy_shot hit detection

if tag is player
then player.damage()
then destroy self

private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.tag == "Player")
        {
            other.GetComponent<Player>().Damage();
            Destroy(this.gameObject);
        }
    }

Game Balance

Game balance is now changed greatly so tweak the numbers: spawnrate, fire rate, bullet speed etc.

Don’t forget to add SFX for the immersion.
