Migrate dari versi 4.6 ke versi 4000 contoh: migrasikan sampel SpatialMap_Sparse_Building

Artikel ini menjelaskan cara memigrasikan sampel SpatialMap_Sparse_Building dari EasyAR Sense Unity Plugin versi 4.6 ke versi 4000.

Ganti paket plugin

Lihat panduan migrasi umum untuk mengganti paket plugin.

Ubah kode yang tidak kompatibel: paling cepat untuk dijalankan

Ganti SparseSpatialMapWorkerFrameFilter di skrip MapBuilding_SparseSample asli dengan SparseSpatialMapBuilderFrameFilter:

Kode versi asli:

private SparseSpatialMapWorkerFrameFilter sparse;

Diubah menjadi:

private SparseSpatialMapBuilderFrameFilter sparse;

Di Awake, perbarui kode untuk mendapatkan SparseSpatialMapBuilderFrameFilter:

Kode versi asli:

sparse = Session.GetComponentInChildren<SparseSpatialMapWorkerFrameFilter>();

Diubah menjadi:

Session.StateChanged += (state) =>
{
    if (state == ARSession.SessionState.Ready)
    {
        sparse = Session.Assembly.FrameFilters.Where(f => f is SparseSpatialMapBuilderFrameFilter).FirstOrDefault() as SparseSpatialMapBuilderFrameFilter;
    }
};

Di Update, hapus kode yang mencetak Status, dan perbarui referensi peta spasial jarang menjadi sparse.Target menggunakan API versi baru:

Kode versi asli:

private void Update()
{
    Status.text = $"Device Model: {SystemInfo.deviceModel} {deviceModel}" + Environment.NewLine +
        "Frame Source: " + ((Session.Assembly != null && Session.Assembly.FrameSource) ? Session.Assembly.FrameSource.GetType().ToString().Replace》("easyar.", "").Replace("FrameSource", "") : "-") + Environment.NewLine +
        "Tracking Status: " + Session.TrackingStatus + Environment.NewLine +
        "Sparse Point Cloud Count: " + (sparse.LocalizedMap == null ? "-" : sparse.LocalizedMap.PointCloud.Count.ToString()) + Environment.NewLine +
        "Cube Location: " + (onSparse ? "On Sparse Spatial Map" : (Session.TrackingStatus.OnSome && Session.TrackingStatus != 》MotionTrackingStatus.NotTracking ? "Air" : "-")) + Environment.NewLine +
        Environment.NewLine +
        "Gesture Instruction" + Environment.NewLine +
        "\tMove to Sparse Spatial Map Point: One Finger Move" + Environment.NewLine +
        "\tScale: Two Finger Pinch";

    if (Input.touchCount == 1 && !EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId))
    {
        var touch = Input.touches[0];
        if (touch.phase == TouchPhase.Moved)
        {
            var viewPoint = new Vector2(touch.position.x / Screen.width, touch.position.y / Screen.height);
            if (sparse && sparse.LocalizedMap)
            {
                var points = sparse.LocalizedMap.HitTest(viewPoint);
                foreach (var point in points)
                {
                    onSparse = true;
                    TouchControl.transform.position = sparse.LocalizedMap.transform.TransformPoint(point);
                    break;
                }
            }
        }
    }
}

Diubah menjadi:

private void Update()
{
    if (Input.touchCount == 1 && !EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId))
    {
        var touch = Input.touches[0];
        if (touch.phase == TouchPhase.Moved)
        {
            var viewPoint = new Vector2(touch.position.x / Screen.width, touch.position.y / Screen.height);
            if (sparse && sparse.Target)
            {
                var points = sparse.Target.HitTest(viewPoint);
                foreach (var point in points)
                {
                    TouchControl.transform.position = sparse.Target.transform.TransformPoint(point);
                    break;
                }
            }
        }
    }
}

Sampel sekarang sudah dapat dijalankan.

Bangun ulang adegan: siap untuk fitur baru

Hapus node Sparse SpatialMap di adegan:

Hapus AR Session di adegan:

Buat ulang AR Session:

Tetapkan ulang ARSession di skrip sampel ke AR Session baru yang dibuat (EasyAR):

Sekarang adegan dan skrip sampel telah diperbarui ke versi 4000.0 dan dapat dijalankan.
