使用鼠标移动在x轴上移动对象

Question

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.

Answer 1

这可能起作用：

transform.position = new Vector3(Camera.main.ScreenToViewportPoint(mouse).x, 0, 0);

Answer 2

You're doing a few things in your code that are unnecessary, mainly the first and third lines. I will try to simplify your code with my answer.

Anyway, you have the mouse's X and Y, so all you need to do is have your object only move to its X position. Right now you assign the object's entire position to match that of the mouse.

Vector3 mouse = Camera.main.ScreenToViewportPoint(Input.mousePosition);
transform.position = new Vector3(mouse.x, transform.position.y, transform.position.z);

This will maintain your object's position along other axes, but align it to the horizontal position of your mouse cursor.
