New Enemy Type with Shield

How to create shielded enemies

To create this behavior we create a new variation of the Enemy Damage script. We created a child game object shield that is set active and when the enemy gets hit it doesn’t take damage and the shield is deactivated. We use the following code:

private void OnTriggerEnter2D(Collider2D other)
{
    //Debug.Log(other);
    if (_isShieldActive == true)
    {
        _shield.SetActive(false);
        _isShieldActive = false;
        if (other.tag == "Player")
        {
            //dmg player
            _player.Damage();
        }
        else if (other.tag == "Laser")
        {
            //destroy laser
            Destroy(other.gameObject);
        }
    }
    else { 
        //if other is player
        if (other.tag == "Player")
        {
            //dmg player
            _player.Damage();
            //add 10 to score
            _player.AddScore(10);
            //destroy us
            StartCoroutine(EnemyDeath());
        }
        //if other is laser
        else if (other.tag == "Laser")
        {
            //destroy laser
            Destroy(other.gameObject);
            //add score
            _player.AddScore(20);
            //destroy us
            StartCoroutine(EnemyDeath());
        }
    }
}
