I'm fairly new to Direct3D so I was hoping someone wouldn't mind helping me out :) I'm making a 2D game using Direct3D and D3DXSPRITE to do my rendering. Is it possible to alpha blend rendered objects? And if so how? What I'm trying to achieve is a fading out effect on some of the images I'm rendering by giving them an alpha value and rendering the image with this alpha value and then decrementing the alpha so eventually the image will fade out and the background will show through. Thanks!

With the Sprite interface, you can pass the flag D3DXSPRITE_ALPHABLEND to the begin function of the sprite interface.

When you pass in a color to the Draw command (pSprite->Draw()), then set the alpha value of it. You can use the D3DCOLOR_RGBA macro.

Good luck,
Chris
