Making camera follow upwards

Question

How do I make the camera follow my character upwards at a certain height, I want the horizontal camera to move upwards after I reach a bit under the top like in New Super Mario Bros. I also need the camera to go back down after the character get under the red line in the photo. I am using unity 5.6.6

alt text I want the camera to follow after the character reaches the red line

So this is my current code, I;m only missing what I mentioned

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class CameraController : MonoBehaviour {
 
     public GameObject target;
     public float followAhead;
 
     private Vector3 targetPosition;
 
     public float smoothing;
 
     // Use this for initialization
     void Start () {
         
     }
 
     // Update is called once per frame
     void Update() {
         targetPosition = new Vector3(target.transform.position.x, transform.position.y, transform.position.z);
 
         //Makes camera move ahead of player
         if (target.transform.localScale.x > 0f)
         {
             targetPosition = new Vector3(targetPosition.x + followAhead, targetPosition.y, targetPosition.z);
         } else {
             targetPosition = new Vector3(targetPosition.x - followAhead, targetPosition.y, targetPosition.z);
         }
 
         //transform.position = targetPosition;
 
         transform.position = Vector3.Lerp(transform.position, targetPosition, smoothing * Time.deltaTime);
     }
 }

hi, if you want camera follows player constantly you can see this link: https://unity3d.com/learn/tutorials/projects/2d-ufo-tutorial/following-player-camera but in if you want to follow the player only up the red line you have to store the first y position and use that after player moves down. I'v changed your code :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class CameraMovement : MonoBehaviour
 {
     public float redLineY;
     public float firstCameraY;
     public GameObject target;
 
     public float followAhead;
 
     private Vector3 targetPosition;
 
     public float smoothing;
 
     private Vector3 targetOffset = new Vector3(0,0,0);
 
     // Update is called once per frame
     void Update()
     {
         //Makes camera move ahead of player
         if (target.transform.position.y > redLineY)
         {
             targetPosition = new Vector3(target.transform.position.x, target.transform.position.y, transform.position.z) + targetOffset;//you can change the offset 
         }
         else
         {
             targetPosition = new Vector3(target.transform.position.x, firstCameraY, transform.position.z);
         }
 
         //transform.position = targetPosition;
 
         transform.position = Vector3.Lerp(transform.position, targetPosition, smoothing * Time.deltaTime);
     }
 }

Thank you so much that works it's following up the way I want beautifully but it doesn't follow ahead in front of the character so I added something to the code but it won't follow ahead the other way when I turn around. Sorry I'm kinda new, also the camera is perfect for my game, I love it so don't worry too much about helping me fix it again :D

  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  
  public class CameraController : MonoBehaviour
  {
      public float redLineY;
      public float firstCameraY;
      public GameObject target;
  
      public float followAhead;
  
      private Vector3 targetPosition;
  
      public float smoothing;
  
      private Vector3 targetOffset = new Vector3(0,0,0);
  
      // Update is called once per frame
      void Update()
      {
          //Makes camera move ahead of player
          if (target.transform.position.y > redLineY)
          {
              targetPosition = new Vector3(target.transform.position.x + followAhead, target.transform.position.y, transform.position.z) + targetOffset;//you can change the offset 
          }
          else
          {
              targetPosition = new Vector3(target.transform.position.x - followAhead, firstCameraY, transform.position.z);
          }
  
          //transform.position = targetPosition;
  
          transform.position = Vector3.Lerp(transform.position, targetPosition, smoothing * Time.deltaTime);
      }
  }

how do you make it is that it only follows it upwards?
