Accessing next Camera from array

Questions & Answers

Hello, I’m doing camera swap so when Player press “C” current camera will be disabled and next camera from the array will be enabled. I know that i can’t use that number to pick array element but I don’t know how to do it other way. I’m not really good with arrays so I’m asking for advice. Here is part of the code:

    GameObject[] availableSpecCameras;
            int number;
            GameObject mainPlayerCamera;
        GameObject nextCamera;
        GameObject lastCamera;
            
            void Start() {
            mainPlayerCamera = GameObject.FindGameObjectWithTag("MainCamera");
            availableSpecCameras = GameObject.FindGameObjectsWithTag("SpecCamera");
            number = availableSpecCameras.Lenght;
            }
            
            void Update () {
            if (Input.GetKeyDown (KeyCode.C)) {
            			if (mainPlayerCamera.gameObject.activeInHierarchy) {
            				nextCamera = availableSpecCameras [number];
            				nextCamera.gameObject.SetActive (true);
            				mainPlayerCamera.gameObject.SetActive (false);
            					number--;
            			} else if (number != 0) {
            				nextCamera = availableSpecCameras [number];
            				nextCamera.gameObject.SetActive (true);
            				lastCamera = availableSpecCameras [number + 1];
            				lastCamera.gameObject.SetActive (false);
            					number--;
            			} else {
            				mainPlayerCamera.gameObject.SetActive (true);
            				lastCamera = availableSpecCameras [number];
            				lastCamera.gameObject.SetActive (false);
                            availableSpecCameras = GameObject.FindGameObjectsWithTag("SpecCamera");
                            number = availableSpecCameras.Lenght;
            			}
            		}
            }

@knightmar Here is some much simplified code for you. First, I used a List because it’s much easier to work with. You can replace it with an array and it will still work. Second, I combined “availableSpecCameras” with “mainPlayerCamera” because you don’t need them separate. If you ever need to refer to the player camera, just use “Cameras[0]” and you can always find it there. Third, I removed the references to the next and previous cameras because they were unnecessary. If you need to access them, use Cameras[counter - 1] for last camera and Cameras[counter + 1] for next (if counter == 0, last is Cameras.Count, if counter == Cameras.Count, next is 0).

List<GameObject> Cameras = new List<GameObject> ();
    int counter = 0;

    void Start () {
        Cameras.Add (GameObject.FindGameObjectWithTag ("MainCamera"));
        Cameras.AddRange (GameObject.FindGameObjectsWithTag ("SpecCamera"));
    }

    void Update () {
        if (Input.GetKeyDown (KeyCode.C)) {
            Cameras [counter].SetActive (false);
            if (counter < Cameras.Count) {
                counter++;
            } else {
                counter = 0;
            }
            Cameras [counter].SetActive (true);
        }
    }

Hope this helped!
