  • PresentParameters.DeviceWindow usage

    Last post by darrellp
      • Does anybody know what PresentParameters.DeviceWindow is used for if anything I've got D3D running in a child window and it works just fine whether I set this parameter or not. Besides that, the parameter does seem a wee bit redundant since the device constructor takes the window as an argument anyway. So is this just a bit of legacy code that is totally unnecessary or are there situations where

      • I'm simply wondering if there is a way to somehow capture the backbuffer contents to a file on the xbox 360 and then transfer that file back to the PC I've checked the framework docs and this forum and it doesn't seem to be possible, but I'm hoping that I am wrong. :-) A screenshot looks slightly less amateurish on a website than if I photograph my TV, even though it still looks like programmer

My xbox360 has just fallen prey to the dreaded " three flashing red lights on the ring of light " issue and, I suspect, will have to be sent in for service. I'm working with support and awaiting their response, but that's not really the issue. I really really wanted my game to be cross platform such that the same code-base built for both windows

      • I'd like to call upon all the shader gurus here for some help :) I've been experimenting with writing some of my own effects, meaning I'm a HLSL newbie, and have been using NVIDIA's FX Composer to do my work. After producing a cool (albeit simple) effect, I decided to try using it in my little model viewer. The problem is that the way it shows up through XNA is different than the way it shows u

Worked through a few of the simpler ones successfully, and gaining a good understanding of HLSL in the process.

      • Update SetDataOptions.Discard is causing the exception to occur on the 360, changing the option to either None or NoOverwrite causes no exception. An interesting point though, on the PC build changing these options has little effect (the particles are still rendered) - the 360 however doesn't appear to render any particles. Strange I've started another thread to address the shader: http:/
