Is it possible to rotate the entire screen orientation?

Questions & Answers

I want to rotate the entire display output for a PC standalone build, the same way you’d expect a mobile app to rotate when you rotate the device (i.e. “Screen.orientation”).

The goal is to create a TATE mode so the game can be played on portrait monitors like an arcade cabinet game.

I’ve managed to achieve a similar effect by changing the Windows display settings, but I want to do it in-game so users don’t have to do that whenever they play the game.

Is that even possible? And if so, how?

Thanks!

Certainly! If you don’t want to change the screen resolution in Windows you could always just rotate your camera -90 on the z axis.

Your UI and controls would also have to be rotated accordingly.

One way to rotate your canvas would be to add a Grid Layout Group to it:

I set the cell size to be my screen resolution and made sure I set the canvas to Screen Space Overlay.

Next I added a layout object that could be set to fill the whole screen and contain all my UI items. That item should be set to fill the whole screen. I added all my UI elements under it.

Finally I added a script to my canvas. The script has a “tateMode” boolean to track the current state and rotates the camera and UI to match. The script I made is below, and I’ve zipped the whole project and attached it so you can test it out. I think using this the controls could remain the same.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class FlipToTATE : MonoBehaviour {

    private bool tateMode;
    public GameObject myCamera;
    public GridLayoutGroup myGrid;
    public RectTransform layoutRotator;

	// Use this for initialization
	void Start () {
        tateMode = false;

    }
	
	// Update is called once per frame
	void Update () {
        if (Input.GetKeyUp(KeyCode.Space))
        {
            tateMode = !tateMode;
            if (tateMode)
            {
                myCamera.transform.eulerAngles = new Vector3(0f, 0f, -90f);
                layoutRotator.eulerAngles = new Vector3(0f,0f,90f);
                myGrid.cellSize = new Vector2(Screen.currentResolution.height, Screen.currentResolution.width);
            }
            else
            {
                myCamera.transform.eulerAngles = new Vector3(0f, 0f, 0f);
                layoutRotator.eulerAngles = new Vector3(0f, 0f, 0f);
                myGrid.cellSize = new Vector2(Screen.currentResolution.width, Screen.currentResolution.height);
            }
        }
	}
}
