      • Hi people. I'm having a problem using effects. Of the 15 or so fx files in the samples, only 2 will successfully go through with my code. It doesn't really make any sense :( I do know that those that fail will cause effect to be null in the following code. Note that this code is from a wrapper and each new effect will be in its own object that initializes using the code: DX9Effect::DX9Effect(char*

      • I caught some people quoting managed performance loss at only 2% (over unmanaged). I am just curious how accurate that assessment is. Last time I was looking into it, DX programmers were quoting 90% of managed performance as a BEST case scenario. (usually much lower) If the margin has grown so low, is there any large scale games developed using C#

      • Well, I finally decided to write a little utility that checks for the required components of XNA (excluding .Net2.0 because i wrote it using .net 2.0 ) because I've seen just too many threads about the game not working on non-dev pcs. This program lets the user know if they have an outdated graphics card, installs the latest directx using directx webinstall, and installs the xna framework red

I've got a problem and i think it has something to do with uv-sharing. i want to render my helicopter - in rendermonkey everything looks fine (with culling set to counter-clock-wise!!) but in XNA many parts do not get rendered. As it seems, they are exactley those parts which share some texturecoordinates with other parts (i.e. I textured only one side of the helicopter and use this texture fo

      • I am making an FPS. In the FPS, your gun is visible to you (in first person) as it would be in CS. The problem I am having is that other objects will show over this mesh if they are close enough. Is this because I have a bad projection/view/fov set up, or is there some way I can make sure this one model stays on top of all of the other models no matter what. I'm not really sure how t

The object is a big bowl, and I need the selection of vertices around the edge of the bowl, that way I can render something such as water in the object. How do you suggest I'd do something like this Thanks

      • Hello, I'm having a bit of trouble rotating models around their own centers; instead any new physical object I place in the world will perform its rotations from the world origin, not their own. I understand that the order of the matrices matter, and as far as I know I'm applying these correctly. Each object is a DrawableGameComponent and has its own transform matrix. In the drawing code updates b

      • I'm having a big problem on moving vertices with the mouse. Using the Vector3.Unproject, automaticly sets the Z coordinate for a point (the distance from camera)(in my case to 7). When I set the Z coordinate of a vertex to 2, it's not on the same position on the screen as the mouse is. How do I unproject a Vector without modifying it's Z coordinate, but the Vector coordinate to look on the screen

      • I've been simply using the A8R8G8B8 and X8R8G8B8 format to create textures for quite some time. These formats are quite commonly supported in recent years, as well as R5G6B5, DXTn, etc. But I'm just thinking that in theory they're not guaranteed to succeed, and it may need some fallback to other formats. It reminds me of the OpenGL way that you can pass in data in any format and it will convert th
