Something like this should get it working

public enum Direction { Left , Right }

// Given the player's position and an other's 
// return where the "other" object should face to look at the player
public Direction GetDirection(Vector2 player , Vector2 other)
{
     return player.x < other.x ? Direction.Left : Direction.Right;
}

As for how to make the other actually use this method to look in the right direction , there are many ways, you can either :

  • set the object’s rotation.y to 0 or 180
  • set the object’s scale.x to 1 or -1
  • set SpriteRenderer’s flipY to to true or false
