   Point light
  Hello trying to get a point light to work.  My game is 2D so I just have a camera facing a plane of squares.I have each square a normal that is pointing towards the camera (I guess this is right way).  And a material with ambient and diffuse set to white.here is my code[source = "csharp"]   Material m = new Material();   m.Ambient = new Color4(1f, 1f, 1f, 1f);   m.Diffuse = new Color4(1f, 1f, 1f, 1f);   device.Material = m;   device.SetRenderState(RenderState.Lighting, true);   device.SetRenderState(RenderState.Ambient, Color.White.ToArgb());   device.SetRenderState(RenderState.AmbientMaterialSource, ColorSource.Material);   device.SetRenderState(RenderState.DiffuseMaterialSource, ColorSource.Material);   Light light = new Light();   light = new Light();   light.Type = LightType.Point;   light.Position = new Vector3(0, 0, -1);   light.Ambient = Color.White;   light.Diffuse = Color.White;   light.Range = 500;   light.Attenuation0 = 1f;   light.Attenuation1 = 0f;   light.Attenuation2 = 0f;   //light.Direction = new Vector3(0, 0, 1f);   device.SetLight(0, light);   device.EnableLight(0, true);This just gives me black.  I check in PIX and the normals are correct.   
  The light must be on the same side of the squares as the camera and, since it's a point light, close enough to the squares to illuminate them.;  Light light = new Light();   light = new Light();Not related to your problem...but not good.   ;  ty guys i get better idea now   ;Sry, I just so happy with outcome that I have to post picture ^_^   ;  Congratulations !
