How do I make the camera follow my character moving up but not down

Question

I am making my first mobile game where the player controls a jetpack and the goal is to get as high as possible, I have a camera follow script and my next step is to have it not follow the player if the player is descending. an example of how i want the camera to function is doodle jump where the player dies once he goes below the screen but my game is 2.5D, i've tried checking players velocity and if it is negative then don't follow but nothing is working

You can check the position of the camera vs its position in the last frame, if is lower than the last position then stop your follow script

 Float lastPos;
 Float camPos;
 Bool follow;
 
 
 Void LateUpdate() 
 { 
    camPos = gameobject.transform.position.y; //vertical position of the camera 
    If(camPos >= lastPos) 
       {
         lastPos = gameobject.transform.position.y; 
         follow = true; 
        } else 
          { 
            lastPos = gameobject.transform.position.y;
            follow = false; 
           } 
 }

Then something like this

 void Sart()
 {
 YourFollowScrip camFollow = gameobject.GetComponent<YourFollowScript>();
 }
 
 void Update()
 {
 camFollow.enable = follow;
 }

Just a solution off the top of my head, why not use something like

 transform.position = new Vector3(x, Mathf.Max(new_y_value, transform.position.y), z);

That way, it can only either be the height you give or the current height.
