Using Sprite to draw 2D graphics

Hi all,

I use Sprite class to draw Bitmaps on the screen. In the sprite class, I only know how to do some simple effects on the texture, such as setting the transparency.

The problem is that I want those textures to be affected by Lighting.
E.g. If the color in the texture is blue, the outcome result is Green.
Also I want to do other effects like a spot light on the texture. I have read a book (C++) and seems that I have to use "device->draw primitives" instead of Sprite to do such effects. But I don't know whether there are simply ways to do that(in C# and MDX).
Thank you

You cannot make sprites (i mean ID3DXSprite drawn textures) be affected by lighting or any other effect.

You should study the 3D rendering basics.

The trick is to draw a screen aligned quad, with the appropriate texture.

Hi!

You can load bitmap with transparency layer (alpha layer).

I am reading a book that has a chapter in on the basics of Managed DirectX, in this chapter there are some small samples that will help you do the task at hand.

I would suggest having a look at it, although it is using an older version of the SDK, the principles are the same. Check out "Beginning .Net Game Programming in C#, by David Weller and co"

You might want to do some searching and research on Textured Quads on www.gamedev.net and on Google.
