C# + Some directdraw questions
Hi all,
I am developing a graphics engine using DirectDraw and C#.
It is working very nice, but I have a few questions:
1) I have a big island with some bugs. I want them to rotate. How can I rotate a bitmap surface?
2) My graphics engine is able to resize and draw everything in the right size. However, when I am using large images which are getting very small, it looks very ugly. (wrong, as it should be). Is there anything I can do about this?
Thanks!

In DirectDraw, you can't. You have to rotate a virtual quad, and write a texture mapper that locks the target surface and maps the bmp into it. Basically, a mini -software-rasterizer.

Make the original bitmap small in size. In general, a 2D asset should have a size the same as or near to the one it has in game.
Hello,
Thanks for the reply! Too bad that option 1) is not possible in directdraw.
I have one question left. I am using this code
The strange thing is that the destrect function is failing. When I don't use the destrect, everything works, but when using destrect, the surface is not drawn in the rectangle I want it to be.
Any idea what I am doing wrong?

// Create our destination rectangle pntTarget = m_oRenderTarget.PointToScreen(m_oRenderTarget.Location); oDestRect = new Rectangle(pntTarget, m_oRenderTarget.Size); // Try to draw try { m_oSurfacePrimary.Draw(oDestRect, m_oSurfaceSecondary, DrawFlags.DoNotWait); } catch (SurfaceLostException) { // Create the surfaces CreateSurfaces(); }
