Hi,

I started to write an overhead 2D game using Managed DirectDraw in VB .Net and was hoping to use 3D Sprites in order to rotate the game character using Direct3D.

I can't seem to gain access to any background surface in Direct3D to blit the results of the DirectDraw off-screen scroll buffer. So, I' m thinking that I need to do everything in Direct3D?

What is a good way to create a scrolling background in Direct3D? If I'm using a tile-based engine, how do I blit to a large surface in Direct3D? Or, do I use small polygons for each tile? Can I blit from a tile surface to the individual 3D Sprite tiles? Or, can I only load a texture from a file? Is there blitting/.Draw support for Direct3D?

Thanks,

Jim
 
There is a Sprite class within Direct3D (and a simplified version in D3DX I believe, but I use the Direct3D one). To do the actual drawing all you have to do is a call such as this:

Sprite theSprite = new Sprite(device);

theSprite.Draw(texture, rectangle, scale, rotationPoint, rotationValue, translation, color);

You would just call Draw for each of your background tiles, I am using this for a 2d game I'm making and it works quite well. Also remember to draw the background first :)

Hope that helps!
