using UnityEngine;

public class Example : MonoBehaviour { //Attach a new Camera in the Inspector window public Camera m_SecondCamera; //This is set as the main Camera in this script Camera m_FirstCamera;

void Start() { //Disable the second Camera m_SecondCamera.enabled = false; //Set where to place the second Camera along with its width and height m_SecondCamera.pixelRect = new Rect(0, 0, 400, 200); //Set the first Camera as the main Camera m_FirstCamera = Camera.main; }

void Update() { //Press the space key to toggle the second Camera and output camera pixel width and height if (Input.GetKeyDown(KeyCode.Space)) { //Check if the second camera is enabled yet if (!m_SecondCamera.enabled) { //Toggle the second Camera and output the second Camera's details ToggleCamera(m_SecondCamera, m_SecondCamera); } else { //Toggle the second Camera and output the first Camera's details ToggleCamera(m_SecondCamera, m_FirstCamera); } } }

//Toggle the Camera and output the Camera specified void ToggleCamera(Camera cameraToggle, Camera cameraOutput) { //Set Camera on and off cameraToggle.enabled = !cameraToggle.enabled;

//Output the Camera's new Pixel width Debug.Log("Pixel width :" + cameraOutput.pixelWidth + " Pixel height : " + cameraOutput.pixelHeight); } }
