C# Moving object on x axis with mouse move

Hi, I am trying to create a game where the player drops a cube from the top of the screen to the bottom, collecting points on the way down depending on where they dropped the cube from (like a Coin Pusher arcade game).

At the moment I am able to have my cube move to the mouse, but this in both X and Y values. See -
Camera.main.ScreenPointToRay(Input.mousePosition);
Vector3 mouse = Input.mousePosition;
mouse = mouse;
transform.position = Camera.main.ScreenToViewportPoint(mouse);

I am keen to have movements only on X but am unsure how to achieve this.

Thank you,

Just use the result of ScreenToViewportPoint(), create a new Vector3 from it, but leave the Y at 0.

 

I have 'fixed' the issue by changing the first posts code to:
Vector3 mouse = Camera.main.ScreenToViewportPoint(Input.mousePosition);
transform.position = new Vector3(mouse.x, transform.position.y, transform.position.z);

But the movement from a mouse is very slow and not very responsive. Is there a way to speed up, or more accurately follow my mouse movements?

 

Sounds to me like low framerate not an issue with this code specifically. What's your framerate? (click on stats in the play window)

 

lol its the code
