Xamarin Forms - Urho - 创建场景网页

这是我第一次使用urhosharp，我有一些问题。我尝试了一些示例示例，但我的应用崩溃了。Xamarin Forms - Urho - 创建场景网页

我安装了NuGet包UrhoSharp.Forms

我只是想创建一个场景，摄像机在此我可以360度旋转的中间。

这是我的网页：

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)); 


     } 
    } 
}

，我不得不删除那些2线，因为我渐渐的错误。渲染器和上下文未设置。我从那些没有使用页面的功能样本中获得了这个功能

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

浮的的Vector3（）为您的平面节点规模，FogStart，FogEnd和FarClip应该浮动。
如果我们不知道上下文您的视口，Urho肯定崩溃。

通过用typename：Node，Component，Renderer替换'var'来提高应用程序的稳定性。

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)); 
} 

}}
