Xamarin Forms - Urho - 創建場景網頁

這是我第一次使用urhosharp，我有一些問題。我嘗試了一些示例示例，但我的應用崩潰了。Xamarin Forms - Urho - 創建場景網頁

我安裝了NuGet包UrhoSharp.Forms

我只是想創建一個場景，攝像機在此我可以360度旋轉的中間。

這是我的網頁：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

using Urho; 
using Urho.Forms; 

using Urho.Resources; 
using Urho.Gui; 

using Xamarin.Forms; 

namespace testApp.Pages.Urho 
{ 
    public partial class urhoPage : ContentPage 
    { 

     Scene scene; 
     Camera camera; 

     protected Node CameraNode { get; set; } 


     public urhoPage() 
     { 
      InitializeComponent(); 

      scene = new Scene(); 

      scene.CreateComponent<Octree>(); 
      scene.CreateComponent<DebugRenderer>(); 

      var planeNode = scene.CreateChild("Plane"); 
      planeNode.Scale = new Vector3(100, 1, 100); 
      var planeObject = planeNode.CreateComponent<StaticModel>(); 

      // Create a Zone component for ambient lighting & fog control 
      var zoneNode = scene.CreateChild("Zone"); 
      var zone = zoneNode.CreateComponent<Zone>(); 

      // Set same volume as the Octree, set a close bluish fog and some ambient light 
      zone.SetBoundingBox(new BoundingBox(-1000.0f, 1000.0f)); 
      zone.AmbientColor = new Urho.Color(0.15f, 0.15f, 0.15f); 
      zone.FogColor = new Urho.Color(0.5f, 0.5f, 0.7f); 
      zone.FogStart = 100; 
      zone.FogEnd = 300; 

      // Create the camera. Limit far clip distance to match the fog 
      CameraNode = scene.CreateChild("Camera"); 
      camera = CameraNode.CreateComponent<Camera>(); 
      camera.FarClip = 300; 

      // Set an initial position for the camera scene node above the plane 
      CameraNode.Position = new Vector3(0.0f, 5.0f, 0.0f); 

      // var renderer = Renderer; 
      //renderer.SetViewport(0, new Viewport(Context, scene, camera, null)); 


     } 
    } 
}

，我不得不刪除那些2線，因爲我漸漸的錯誤。渲染器和上下文未設置。我從那些沒有使用頁面的功能樣本中獲得了這個功能

// var renderer = Renderer; //renderer.SetViewport(0，new Viewport（Context，scene，camera，null））;

浮的的Vector3（）爲您的平面節點規模，FogStart，FogEnd和FarClip應該浮動。
如果我們不知道上下文您的視口，Urho肯定崩潰。

通過用typename：Node，Component，Renderer替換'var'來提高應用程序的穩定性。

using Xamarin.Forms; 
namespace testApp.Pages.Urho 
{ 
public partial class urhoPage : ContentPage 
{ 
Scene scene; 
Camera camera; 

protected Node CameraNode { get; set; } 


public urhoPage() 
{ 
    InitializeComponent(); 

    scene = new Scene(); 

    scene.CreateComponent<Octree>(); 
    scene.CreateComponent<DebugRenderer>(); 

    var planeNode = scene.CreateChild("Plane"); 
    planeNode.Scale = new Vector3(100f, 1f, 100f); 
    var planeObject = planeNode.CreateComponent<StaticModel>(); 

    // Create a Zone component for ambient lighting & fog control 
    var zoneNode = scene.CreateChild("Zone"); 
    var zone = zoneNode.CreateComponent<Zone>(); 

    // Set same volume as the Octree, set a close bluish fog and some ambient light 
    zone.SetBoundingBox(new BoundingBox(-1000.0f, 1000.0f)); 
    zone.AmbientColor = new Urho.Color(0.15f, 0.15f, 0.15f); 
    zone.FogColor = new Urho.Color(0.5f, 0.5f, 0.7f); 
    zone.FogStart = 100f; 
    zone.FogEnd = 300f; 

    // Create the camera. Limit far clip distance to match the fog 
    CameraNode = new Node(); 
    Camera camera = CameraNode.CreateComponent<Camera>(); 
    camera.FarClip = 300.0f; 

    // Set an initial position for the camera scene node above the plane 
    CameraNode.Position = new Vector3(0.0f, 5.0f, 0.0f); 

    var renderer = Application.Current.Renderer; 
    renderer.SetViewport(0, new Viewport(Application.CurrentContext, scene, CameraNode.GetComponent<Camera>(), null)); 
} 

}}
