XNA Essentials

Game Programming for Xbox 360, PC + Windows Phone


Problem in Chapter 4

Hello fellow XNA Programmer!

I have a problem. In the section in Chapter 4 where, you venture to find out the difference in performance of the DrawUserPrimitives and DrawPrimitives methods, you found nothing. However, I found one important thing. While the performance between the two version may have not been altered, the display was: the DrawIndexedPrimitives method showed nothing at all!


So now what? I've checked my programming, and the errata, and have done everything right. Have I missed a post where this was covered?

Re: Problem in Chapter 4

Sorry for missing this post.  I hadn't check the original book forums in quite a while.  Are you using the original book or XNA Game Studio 3.0 Unleashed?

If so, this thread (in the 3.0 book forum) may help:


Again, sorry for the late response.  I guess I need to close down this forum for the original book.
