Multiple Prefab Instantiation, Camera, Button and Scroll View Question

Questions & Answers
1

I am trying to:

Instantiate a prefab Sphere Game Object
Instantiate a prefab Camera and assign it as a child of the new prefab Sphere Game Object
Instantiate a prefab button that includes the script to switch the camera from the default to new
Add the new button to a scroll view canvas object as a child

This is what I have so far:

    public Camera CameraPrefab, DefalutCamera;
    public Camera[] cameras;
    private int currentCameraIndex;
    public Transform GenericCanvasScrollViewObject;
    public Button ButtonPrefab;
    public GameObject SpherePrefab;

`   void NewSphereObjectSetup()

    {
          GameObject newSphere = Instantiate(SpherePrefab, SetSpawnPos, Quaternion.identity);
          Camera newCamera = Instantiate(CameraPrefab);
          newSphere.transform.parent = newCamera.transform;
          Button newButton = Instantiate(ButtonPrefab);
          newButton.onClick.AddListener(SwitchToCamera(newCamera));
          newButton.transform.SetParent(GenericCanvasScrollViewObject);
    }

    public UnityAction SwitchToCamera(Camera anyCamera)
    {
          DefalutCamera.enabled = false;
          anyCamera.enabled = true;
    }

There are no errors until I get to the SwitchToCamera in the UnityAction.
Error not all code paths return a value.

Any ideas? Or Am I on the wrong path altogether?
(SetSpawnPos is brought in from another working function, please ignore the script exclusion)

At this point I will start basic and I will add the rest of what I need when I get the a working version of just one.

I need to

  • instantiate a SphereObjPrefab
  • instantiate a ButtonObjPrefab
  • add the instantiated newButtonObjPrefab to an existing Scroll View, Scroll Rect transform
  • switch the main camera to the newSphereObjPrefab on newButtonObjPrefab on Click()

That is it. The characteristics of the newSphereObjPrefab or newButtonObjPrefab, or even the camera setting don’t matter at this point. I just need to make a sphere, click the button, and see it. Any help is greatly appreciated. Thanks for your response.
