  • FX effect varying by time?

    Last post by Bill Reiss
      • I have a Vertex Shader in an fx file that I created in NVIDIA FX Composer, and it contains a timer parameter as follows: float Timer : TIME < string UIWidget = "None"; >; I then use the Timer variable in my shader. In FX Composer I get the result I want, with the shader varying over time. In XNA, I just get the same deformation all of the time, like the timer is set to a c

      • I am converting some MDX code to XNA and ran into this issue. My old code used Device.CreationParameters.FocusWindow to get the control that the device was associated to. XNA instead provides the FocusWindowHandle. Am I able to convert the handle back to a control some how Thanks

      • This seems to be a common problem, but I've yet to find a real solution. The only thing I've found that works so far is to include a bunch of dlls with XNA applications. What does not work, however, is satisfying the posted requirements: .NET Framework 2.0 XNA Framework DirectX 9.0c (latest update) When a machine satisfies the above requirements, it still cannot run XNA applications (dies when in

      • Hi! This is going to be a newbie question... I am a complete newbie in terms of game development and also a big fan of managed languages :-), so I was extremely happy to read about XNA. I know, this question might seem a bit strange, but I wonder if it is possible to integrate XNA-code (soundrelated) in a "Windows Application". I am not working on a game, but rather on a tool to supp

Now, I'm thinking - what if I want to load a certain model/effect or anything else that the Content Pipeline supports - BUT I want to load it dynamically/at run-time, e.g. I have a certain filename that my code wants to use to load content, but I don't know it until runti

      • Hi All I have created some 2d textures from bmp files and want to combine them in a new texture. I have been trying the surface getData()/setData() commands unsuccessfully. In fact if I get the data from a surface, modify only one pixel of it, and set the data back to the same surface I get a graduated pattern instead of just a pixel being modified Which is not really what I was expecting.

Any Y movement is supposed to make my model move along the Z axis. Any X movement causes the model to rotate around the Y axis. Simple enough. When I move the joystick directly forward the model moves...if I move the joystick directl

You want to have the plane model always be rendered to move with it's nose forward. is there a simple way to translate the movement vector into corrolating rotation x,y,z.

The lack of search results on the subject would leave me to believe that there's not a bug in the software, so it must be something on my end. I'm trying to use sin to determine an object's

There's an "introduction to XNA" and a "FAQ" in the documentation, neither of which talk about what actually changed. I can't find any actual release notes, as traditionally used when releasing a new SDK version. Do they exist
