d3d9 vertex buffer
December 30, 2002 05:52 PM
Ok, I have my vertex buffer set up right, the FVF struct set up and everything, but when I try to do a DrawPrimitive, nothing happens. I''ve scoured the DX9 docs and the books I''ve got, but nothing works. My init code and redering code is like this:
I''ve tried changing everything I could find. I''ve asserted everthing that might go wrong, but it runs and shuts down fine, but nothing is shown on screen.

try putting these lines after the beginScene function and in this order:
or this:
I also noticed:
The last parameter should be a Long according to DX8 docs. So try a 0L instead.
Sorry im not more helpful but im not onto DX9 yet !

I''ve tried all that... I''ve also been playing with RenderStates like lighting, culling, and stuff like that. I know the back buffer and everything is working right because I can change the color value and the screen will change colors. I know the vertex buffer is created right because there are no errors in the project file (I output them to a text file) and all my assertions pass.
