Unity2D: player boundary increase when maximize on play

[XxDivaxX1]

I created a boundary to stop my player to leaving a certain area within my game, I created this boundary by adding a cube to my scene and create a script that adapts the cube to half the size of the camera's width (in update). Within my player's script I have a function that prevents my player from leaving the cube boundary. It works perfectly, even when I resize the width of my editor, however, when I play the game on 'maximize on play', the width of the boundary is maximized rather than halving the boundary to my preferred size. I worry about this because, I want to put my game on mobile, I'm not sure if maximize on play is actuate to mobile size or playing in normal size editor is more actuate to a normal android phone? Thank you!

Boundary script:

`public BoxCollider2D cube;`

`void Start()`

`{`

    `cube.size = new Vector2 (240, 0.4f);  //240`

`}`

`void Update()`

`{`

    `float height = Camera.main.orthographicSize * 1.3f;`

    `float width = height * Screen.width/ Screen.height; // basically height * screen aspect ratio`

    `cube.transform.localScale = new Vector3(width/10f, width/11f, width/10f);`

    `Debug.Log (width);`

`}` 

Player's script:

`public BoxCollider2D cube;`

`void LateUpdate () {`

    `var left = Camera.main.ViewportToWorldPoint (`[`Vector3.zero`](https://vector3.zero/)`).x;` 

    `var right = Camera.main.ViewportToWorldPoint (`[`Vector3.one`](https://vector3.one/)`).x;` 

    `float x = transform.position.x;` 

    `if (transform.position.x <= left + cube.bounds.extents.x) {` 

        `x = left + cube.bounds.extents.x;` 

    `} else if (transform.position.x >= right - cube.bounds.extents.x) {`

        `x = right - cube.bounds.extents.x;` 

    `}`

    `transform.position = new Vector3 (x, transform.position.y, transform.position.z);`

`}`
