The following code example shows how to use a LightsFixedCollection class.
' This code example is from the ' Direct3D Mobile Fixed Point Lighting Sample ' of the .NET Compact Framework Samples ' in the .NET Framework SDK. ' The FrameMove method is called once per frame, ' and is the entry point for animating the scene. Public Sub FrameMove() lightData = device.LightsFixed(2) ' Rotate through the various light types If Fix(appTime) Mod 20 < 10 Then device.LightsFixed(2).Type = LightType.Point Else device.LightsFixed(2).Type = LightType.Directional End If ' Make sure the light type is supported by the device. If ' VertexProcessingCaps.PositionAllLights is not set, the device ' does not support point or spot lights, so change light #2's ' type to a directional light. If Not _ device.DeviceCaps.VertexProcessingCaps.SupportsPositionalLights _ Then If device.LightsFixed(2).Type = LightType.Point Then device.LightsFixed(2).Type = LightType.Directional End If End If ' Values for the light position, direction, and color Dim x As Single = System.Convert.ToSingle(Math.Sin(appTime * 2.0F)) Dim y As Single = System.Convert.ToSingle( _ Math.Sin(appTime * 2.246F)) Dim z As Single = System.Convert.ToSingle( _ Math.Sin(appTime * 2.64F)) Dim r As Byte = System.Convert.ToByte((0.5F + 0.5F * x) * &HFF) Dim g As Byte = System.Convert.ToByte((0.5F + 0.5F * y) * &HFF) Dim b As Byte = System.Convert.ToByte((0.5F + 0.5F * z) * &HFF) device.LightsFixed(2).DiffuseColor = _ ColorValueFixed.FromColor( _ System.Drawing.Color.FromArgb(r, g, b)) device.LightsFixed(2).Range = 100.0F Select Case device.LightsFixed(2).Type Case LightType.Point device.LightsFixed(2).Position = _ New Vector3Fixed(4.5F * x, 4.5F * y, 4.5F * z) device.LightsFixed(2).Attenuation1 = 0.4F Case LightType.Directional device.LightsFixed(2).Direction = _ New Vector3Fixed(x, y, z) End Select device.LightsFixed(2).Update() End Sub
