SCRIPTING
----------
MISSLE_ENEMY.CS - Will instantiate the missle object
ENEMY_MISSLE.CS - Missle fired FROM the enemy and the behaviors associated with the missle.

  STEPS FOR SCRIPTING MISSLE_ENEMY.CS
  ---------------------
  - Serialize a GameObject object variable to assign a prefab
  - On spawn, the missle will fire

  STEPS FOR SCRIPTING ENEMYMISSLE.CS
  ---------------------
  WHY WAS A SEPERATE SCRIPT MADE?
    The ENEMY will shoot off the missle. The missle needs to know how to get to the player. Not the enemy.
  HOW IS THE OBJECT CREATED?
    INSTANTIATE the prefab through the missle_enemy script
  WHAT do I need to have for the missle to move in the player direction
    a GameObject to store the player location
  Start() 
    needs to find the player 
  Update()
    Modify the missle transform using translate. Will utilize Vector2.Down * _speed * Time.deltaTime
    Create a Vector3 direction to store the player transform.position and subtract it's own transform.position
    
   Now the missle knows how to move down and the direction of the player. Need rotation to give the effect of a heat seeking missle.
   Found this super neat formula to calculate rotation of the missle based on the player location:
    float rot_z = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
    transform.rotation = Quaternion.Euler(0f, 0f, rot_z + 90);
    
    This handles the missle going in a downward direction at start, after initial spawn, the missle will adjust.
    If the player fired the missle it would be a -90 adjustment of rot_z.
