SimpleFileBrowser and Meta Quest 3s

[gabberthomson]

Hi all, I am a total newbie on Unity, therefore I apologize in advancce for dumb questions. I need to load some files on a meta quest app I am trying to do. The issue is that the File Menu is never shown.
The step I did so far:

• taking the prefab SimpleFileBrowserCanvas from Assets/SimpleFileBrowser/Resources and dragging to the root of the scene (also changed render mode to World Space)
• Modified a metod I was previously using to show files in custom way to use SimpleFileBrowser. The code is at the end of this post
• I have no exception in the log except this one (which I don't know if it's related or not): [Error ] xrGetInstanceProcAddr: XR_ERROR_FUNCTION_UNSUPPORTED

Code where I use FileBrowser:

public void ShowFileBrowser()
{
    if (FindObjectOfType<FileBrowser>() == null)
    {
        UnityEngine.Debug.LogError("ERRORE: Nessun FileBrowser trovato nella scena! Assicurati di aver creato il GameObject.");
        return;
    }

    if (panoramaConverter == null)
    {
        UnityEngine.Debug.LogError("ERRORE: panoramaConverter non è stato assegnato in FileSelector!");
        return;
    }

    if (FileBrowser.CheckPermission() != FileBrowser.Permission.Granted)

    {
        FileBrowser.RequestPermission(); // Richiede il permesso per accedere ai file
    }



    // Abilita la UI del file browser
    FileBrowser.SetFilters(true, new FileBrowser.Filter("Images", ".jpg"));
    FileBrowser.SetDefaultFilter(".jpg");
    UnityEngine.Debug.Log("Menu avvio");
    // Mostra il file browser
    string initialPath = "/storage/emulated/0/Download/";
    FileBrowser.ShowLoadDialog((paths) =>
    {
        if (paths.Length > 0)
        {
            string selectedFile = paths[0]; // Prende il primo file selezionato
            string selectedAudio = selectedFile.Replace(".jpg", ".m4a"); // Cerca il file audio con lo stesso nome

            UnityEngine.Debug.Log("File selezionato: " + selectedFile);
            panoramaConverter.LoadPanorama(selectedFile, selectedAudio); // Carica il panorama e l'audio
        }
    },
    () => { UnityEngine.Debug.Log("File selection cancelled"); },  // Annullato
    FileBrowser.PickMode.Files, false, initialPath, null, "Select a file", "Load");
}

Your code looks good at first glance. Did you position the World Space Canvas to a visible location in your scene? It'll be displayed at exactly where you placed. And can you verify that you made this placement via the root object (SimpleFileBrowserCanvas) and not the SimpleFileBrowserWindow child object? SimpleFileBrowserWindow is restricted to SimpleFileBrowserCanvas' bounds so if you modify the window object instead of the canvas object, there may be issues.

Hi, first fo all, thanks. I managed to maket the window appear, it was just badly positioned besides to my lack of knowledge. Althouh I see it, I don't know how to interact with it through the rays (no rays appear from the controller when pointing). Is it something that I have to implement?

You need to type "t:Canvas" to SimpleFileBrowserCanvas prefab's Hierarchy and delete all Canvas and GraphicRaycaster components from its children. Then replace SimpleFileBrowserCanvas' GraphicRaycaster component with whichever VR raycaster component that other UI canvases use in VR.
