Okay, so problem #2.... calling the correct version of the interface (I think this is the problem?), since I am getting a "violates the constraint of type 'T'" error.
I set up a XNA VertexBuffer using: l = Array.CreateInstance(VertexPositionColor,6) ..... self.vertices = l Then: self.VertexBuffer = VertexBuffer(self.graphics.GraphicsDevice, \ len(self.vertices) * VertexPositionColor.SizeInBytes, \ BufferUsage.WriteOnly) self.VertexBuffer.SetData[Array[VertexPositionColor]](self.vertices) And I get: ValueError: GenericArguments[0], 'Microsoft.Xna.Framework.Graphics.VertexPositionColor[]', on 'Void SetData[T](Int32, T[], Int32, Int32, Int32)' violates the constraint of type 'T'. The documentation for the VertexBuffer.SetData method can be found here: http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.graphics.vertexbuffer.setdata.aspx The methods are: VertexBuffer.SetData (Int32, T[], Int32, Int32, Int32) VertexBuffer.SetData (T[]) VertexBuffer.SetData (T[], Int32, Int32) This works fine in C# with a List of VertexPositionColor objects, so I assume that Array in IronPython is the equivalent ? So why does it not work ? _______________________________________________ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
