Camera Movement for my Platformer

When working on one of my projects, a 2D platformer, I ran into a little coding problem I don't quite know how to solve.
I know how to make the camera move along with the player all the time but I don't want that. I want the camera to move only in x and stay on the same y and only change that when the player get's to the top or bottom of the screen
I tried transform.position.x but it didn't quite work as I wanted it to, meaning it produced a compiler error.
So if any of you could help me that would be really great. Thanks.

 

You can't amend a transform's positional x,y or z individually, you have to adjust the whole property. i.e. create/amend a Vector3 and assign that to the camera.

Some example pseudocode:

Vector3 cameraPos=camera.transform.position;
cameraPos.x=player.transform.position.x;
camera.transform.position=cameraPos;

 

Thank's.
I can work with that.
