I have a issue with UrhoSharp. I want to load a Indoor Map image with 2D texture. I create a scene with Octree(Urho Class)with Box Shape and it's comes in a 3d view. So, how can I achieve the same in 2D view any suggestion or demo will be so helpful.

Thanks in advance.

You can use staticsprite2d to load your 2d texture and view from orthographic camera. Refer https://developer.xamarin.com/api/type/Urho.Urho2D.StaticSprite2D/

       //Create  sprite image
        var floorNode = _scene.CreateChild();
        floorNode.Position = new Vector3(0, 0, 0.0f);
        StaticSprite2D staticSprite = floorNode.CreateComponent<StaticSprite2D>();
        staticSprite.Color = Color.White;
        staticSprite.BlendMode = BlendMode.Alpha;
        var sprite = ResourceCache.GetSprite2D("floorplan_image.jpg");
        staticSprite.Sprite = sprite;

        //Create a camera
        Node cameraNode = _scene.CreateChild("camera");
        var camera = cameraNode.CreateComponent<Camera>();
        camera.Orthographic = true;
        cameraNode.Position = (new Vector3(0.0f, 0.0f, -10.0f));
        camera.OrthoSize = (float)Graphics.Height * PixelSize;

  • Thanks Tobi for your answer. Actually, I am using material to load the Image. – Puneet Mahali Sep 11 '18 at 07:40
  • Thanks Tobi for your answer.Actually, I am using material to load the Image. var plane = baseNode.CreateComponent(); plane.Model = CoreAssets.Models.Plane; var imageUrl = "here Image url"; var wc = new WebClient() { Encoding = Encoding.UTF8 }; var img = new Image(Context) { Name = "MyTextureImage" }; img.Load(new MemoryBuffer(wc.DownloadData(imageUrl))); plane.SetMaterial(Material.FromImage(img)); Image loading fine with 2D, but moving in a 3D way. So, how can I move the Image in a 2D way also when I zoom the Image it should display in a 3D way like Google Map. – Puneet Mahali Sep 11 '18 at 07:50
  • @PuneetMahali If you want panning effect like Google Maps, you can move your camera on XY plane. For zoom effect, change your camera zoom value. https://developer.xamarin.com/api/property/Urho.Camera.Zoom/ – tobi3245 Sep 12 '18 at 08:23
  • I already tried to change the camera zoom value but still moving in 3D. – Puneet Mahali Sep 12 '18 at 13:45
  • How can I zoom on X,Y axis also I tried Orthographic but it's stops the movement? – Puneet Mahali Sep 12 '18 at 13:47
