Problem to draw a mesh buffer (again)

[carlosgc]

Hi to all

I have a problem to draw a mesh buffer.The problem is that my mesh buffer does not appear when I use the drawMeshBuffer() method, only with drawAll().

First, I already have searched about this problem and I have tried a lot of thing but none of that work for me. Second, I am using the .NET wrapper for Irrlicht and I need to know if my code is right before start to think that the problem could be with the wrapper.

As I said before, I have tried a lot of code and below is the last version of my code.

Code: Select all

static void Main(string[] args)
   {
      IrrlichtDevice device =
         new IrrlichtDevice(DriverType.Software, new Dimension2D(512, 384), 32, false, true, true, true);

      device.WindowCaption = "Hello World! - Irrlicht Engine Demo";

      VideoDriver driver = device.VideoDriver;
      SceneManager smgr = device.SceneManager;

      MeshBuffer mb = new MeshBuffer(VertexType.Standard);
      mb.BoundingBox = new Box3D();

      float fSide = 25f;
      Vector3D vec3D = new Vector3D(-fSide, 0, -fSide), vecN = new Vector3D(0f, 1f, 0f);
      Vector2D vec2D = new Vector2D(0f, 0f);
      mb.SetVertex(0, new Vertex3D(vec3D, vecN, Color.White, vec2D));

      vec3D = new Vector3D(-fSide, 0, fSide);
      vec2D = new Vector2D(1f, 0f);
      mb.SetVertex(1, new Vertex3D(vec3D, vecN, Color.White, vec2D));

      vec3D = new Vector3D(fSide, 0, -fSide);
      vec2D = new Vector2D(0f, 1f);
      mb.SetVertex(2, new Vertex3D(vec3D, vecN, Color.White, vec2D));

      vec3D = new Vector3D(fSide, 0, fSide);
      vec2D = new Vector2D(1f, 1f);
      mb.SetVertex(3, new Vertex3D(vec3D, vecN, Color.White, vec2D));

      mb.SetIndex(0, 2);
      mb.SetIndex(1, 0);
      mb.SetIndex(2, 1);
      mb.SetIndex(3, 2);
      mb.SetIndex(4, 1);
      mb.SetIndex(5, 3);

      Mesh m = new Mesh();
      m.AddMeshBuffer(mb);

      SceneNode node = smgr.AddMeshSceneNode(m, smgr.RootSceneNode, -1);
      node.SetMaterialTexture(0, driver.GetTexture("num.png"));
      node.SetMaterialFlag(MaterialFlag.Lighting, false);
      mb.Material = node.GetMaterial(0);

      CameraSceneNode cam = smgr.AddCameraSceneNode(smgr.RootSceneNode);
      cam.Position = new Vector3D(50, 100, 0);
      cam.Target = new Vector3D(0, 0, 0);

      while (device.Run())
      {
         driver.BeginScene(true, true, new Color(255, 0, 0, 0));

         driver.SetMaterial(mb.Material);
         driver.SetTransform(TransformationState.World, node.AbsoluteTransformation);
         driver.DrawMeshBuffer(mb);
         
         //smgr.DrawAll();

         driver.EndScene();
      }
      //In the end, delete the Irrlicht device.
      device.Dispose();

What's is wrong with my code? Any solution for me?
Thanks in advance.
