Vector3.MoveTowards while also following cursor? - unity3d

Question

I'm making a character that follows my mouse position.
I also have enemies that are being instantiated and would like that character to move towards the location of the enemy but be a few feet higher than the enemy.
Since my character is a flying enemy I'm unsure how to use move towards in unity.
When my enemies are destroyed I would also like the character to continue following the cursor.
public class FollowCursor : MonoBehaviour
{
// Use this for initialization
void Start ()
{
}
// Update is called once per frame
void Update ()
{
if(GameObject.FindWithTag("Enemy"))
{
transform.position = Vector3.MoveTowards.GameObject.FindWithTag("Enemy").transform.position;
}
else
{
transform.position = Camera.main.ScreenToWorldPoint( new Vector3(Input.mousePosition.x,Input.mousePosition.y,8.75f));
}
}
}

I understand you wish to move towards a flying enemy and/or have the flying enemy move towards your character.
I also understand that you wish to use the MoveTowards method to do this.
You should be able to do this by ignoring the Y position or setting it to a fixed value.
Like this.
//Method used: Vector3 MoveTowards(Vector3 current, Vector3 target, float maxDistanceDelta);
//Set movespeed/steps
float speed = 5f;
float step = speed * Time.deltaTime;
//Define y position
float yourFixedYValue = 8.75f;
//Find target
Vector3 enemyPosition = GameObject.FindWithTag("Enemy").transform.position;
Vector3 target = new Vector3(enemyPosition.x, yourFixedYValue, enemyPosition.z);
//Move from current position towards target with step increment.
transform.position = Vector3.MoveTowards(transform.position, target, step);
Please elaborate what you mean if this didn't answer your question.
EDIT:
To move towards the mouse you could use a Raycast something like this inside your Update method.
if (Input.GetMouseButtonDown(0))
{ //If left mouse clicked
RaycastHit hit;
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); //Fire ray towards where mouse is clicked, from camera.
if (Physics.Raycast(ray, out hit)) //If hit something
target = hit.point; //point is a vector3 //hit.point becomes your target
}
That "something" can be any collider, also an enemy one. So can be used to move around in general and to move towards enemies.
