    - Dealing With .X Files To Effects / Shaders usually, a .x file will contain things like; vertex positions, normals, texture coordinates, materials, bones, animations. here is an article that defines everything that can be contained in a .x file ( link ). yes, .x files can contains references to .fx shaders. here's a tutorial for linking your shaders to your .x models in 3ds max ( link ). you could also manually link them within your .x file if your handy with notepad. for writing your shader and setting the parameters in XNA, here is a tutorial provided in the XNA Documentation ( link ). you can find out what vertex declaration XNA passes in by accessing the VertexDeclaration in Microsoft.Xna.Framework.Graphics.Model.Meshes.MeshPart. you can get the VertexDeclaration from a .x file, that data is contained in the DeclData template (although, from what i've seen, not many meshes contain this). but a lot of this is simplified by the XNA Framework. here is a tutorial for the simplest way to load and render a mesh with effects ( link ).

    - Rotating points in 3D I'm not sure if this is helpful specifically to DirectX but I can give you a general overview on transforming points in 3d, and on rendering 3d points on to a 2d plane. In 3d space you have the 3 standard basis vectors e1 e2 and e3, one is pointing in positive x dir (length 1) the other in y, the next in z. So we have: e1 = (1,0,0) e2 = (0,1,0) and e3= (0,0,1) Now if you want to rotate a vector by n degrees on some axis. simply rotate e1 , e2, and e3 by n degrees on that axis , the new values for e1, e2 and e3 will be the columns of your transform matrix. For example if we rotate e1(the x Axis) 90 degrees about the z Axis in the negative x direction the new vector will obviously be pointing towards the y Axis so the transformed vector is : (0 1 0) now rotate e2 and we get (-1, 0, 0) rotating e3 about the z axis gives no change so t(e3) = (0,0,1) from this we make our transform matrix: 0 -1 0 1 0 0 0 0 1 that's all there is to it, if you use angles other than 90 you might need to figure out the components of the vector using simple trig but other than that it's easy Projecting points on to a plane is a bit tricky to explain To find the Y coordinate: You calculate the distance of the object (point) from you in the xy plane: dist = sqrt((myX-objX)^2 + (myY-objY)^2) you can then find the Y coordinate using this inequality: (ObjZ-MyZ)/dist = (screenY) / focalLength You choose an arbitrary focal Length (this will determine how skewed the image is!) Finding X coordinate is done in much the same way: (ObjY-MyY)/(ObjX-MyX) = otherFocalLength/(screenX) MyX, Y, Z are your camera coordinates, you might have to play around with the camera position and focalLengths to get it to look perfect. All you are really doing is using properties of similar triangles I dunno if that helps you at all but it's good to know how things work, and transform matrices are certainly very important Tag: XNA Framework Where is the PositionColoredNormal Vertex type in XNA?

    - Anyone else rolling their own numerics? Just wondering how many other people out there are finding that XNA numerical classes/structures fall a little short of their needs and therefore are writing their own For us, we needed to give our scene graph objects a coordinate frame where the rotation, scale, and translation transformation components are kept separate from one another; this is something similar to what is described in the book 3D Game Engine Architecture ( http://www.amazon.com/Game-Engine-Architecture-Engineering-Applications/dp/012229064X ). XNA didn't quite fulfill this niche, which is understandable as I imagine one constraint during its design was to make it easier to use. So, in the end, I'm thinking about writing my own 3x3 matrix struct, and my own Transform struct (which represents the above mentioned coordinate frame construct). Has anyone run into any problems integrating their owns numerics with XNA's Tag: XNA Framework Where is the PositionColoredNormal Vertex type in XNA? Game Technologies: DirectX, XNA, XACT, etc.

    - Calculating normals for large mesh with no vertex to triangle info Imagine a pyramid with its top cut off. Only the very very last bit of the top is removed leaving a square of 1mm^2, while the pyramids base area is 100x100 meters. You would calculate the four normals at the top as the average of the connected faces. In a way this is correct, but then you interpolate the normal down the sides to calculate lighting and you get the effect of a 1mm^2 horizontal surface imposing its normal on the sides and influencing it just as much as the huge surface. That explanation may be somewhat wanting without actual numbers, but the normals will be calculated wrong. Yes, on the very vertex where you calculate the normal, it will be correct, but when interpolating it away from that exact vertex position, it is very much wrong. This is ofcourse for smooth shading.

    - XACT with XNA Hi I recently attempted to use XACT for a 2d game using C++, and i got an error when loading the global settings file, which i never managed to debug and so used a different audio API instead. Now i am coding audio for a 3D game using XNA and C#, the same thing happens when i attempt to load the xgs file. However it throws a much more helpful sounding Exception: "XACT could not load the data provided. Make sure you are using the correct version of the XACT tool." I have checked that i have the most up to date, december 2006 version of XACT. I heard that only the august 2006 version of the actual creation tool works with XNA, is this true it seems a bit silly if it is, does it mean i have to use the august 06 version of DirectX if i want to use XNA properly Is there anyway of just downloading august 2006 version of XACT without reinstalling the whole SDK Also does anyone know if is there any plans in giving XACT anywhere near half the useful features that DirectSound has Thanks :) Tag: XNA Framework Where is the PositionColoredNormal Vertex type in XNA?

    - Sprite Blitting question - Wondering if this is still a problem here we go: OK, for my textures I had this issue using both a .PNG fine and a .dds I made using the texture tool (from both my PNG and a .BMP after following the XNA guide). My sprites weren't standard sizes. The player sprite was 96x54 (here's a link to a .png of it: http://img46.imageshack.us/img46/8177/playerfx0.png - note that that's a tileset with a walking animation) At the moment I'm having trouble finding a screenshot I took that clearly shows the problem, but I'll keep looking. I do have a video of it, though: http://www.nformant.net/XNA/movie1.avi If you blow the video up to fullscreen, you can see that in the very beginning the player sprite looks very good. As I move it to the right side of the screen, it gets a white outline (around 3 seconds in or so), and this disappears again as it moves back left. It's not simply a video compression error, as I made the video to show off what i was noticing while playing. I found part of the code I was using in my Move function that set the new location for the player. Here it is: //this is the movement function. It moves the player around based on the controller values it's sent public void Move(float x, float y) { //This moves the X and Y locations for the player based on how the thumbstick is pointing location.X += 2 * ( (float) ( Math.Cos( Math.Atan2( (double)y, (double)x ) ) ) ); location.Y -= 2 * ( (float) ( Math.Sin( Math.Atan2( (double)y, (double)x ) ) ) ); Tag: XNA Framework Where is the PositionColoredNormal Vertex type in XNA?

    - Could C# be the future of gaming? I develop serious games/simulations at my job and we use C++ exclusively, and any loss of performance would put us below our minimum requirements for framerate, etc. However, I plan on downloading the new XNA software and learning C#. Since hardware can make up for some performance loss in the future, and for some smaller applications it would be great to reduce dev time and the number of lines of code when performance is not as important. At some point the total cost of developing an application is offset by the performance gain you would get with using C++, if C# is really as easy as I have read about.

I'm migrating from mdx to xna but I can't seem to find the xna equivalent of the mdx vertex type 'PositionColoredNormal' how do i get this vertex type in XNA

I just want a texture-less colored cube with lighting, it seems strange that there is a more complex VertexPositionNormalTexture type, but no VertexPositionNormalColor type...

Am I missing something here

Re: XNA Framework Where is the PositionColoredNormal Vertex type in XNA?

dczraptor

There is no VertexPositionColorNormal in XNA. You can implement your own vertex types though. I'm not sure why they were left out thuogh. It wouldn't be too hard to implement the 7 different basic vertex structures.

Re: XNA Framework Where is the PositionColoredNormal Vertex type in XNA?

Ceres629

Thats strange...

While i love the structure of the XNA framework over the old MDX one, being a beginner I find there are some very strange and simple things missing from it that were in MDX (like meshes)

Creating a lit non-textured coloured cube or a sphere at run time in mdx was incredibly easy. Now with both meshes gone AND ColoredNormal vertex types gone in XNA I'm completely clueless as to what to do.

The general message is that u can create your own mesh class or vertex type and that it is easy to implement, but if it is so easy to implement why not just include it anyway Does anyone know where i can find some code that implements the Mesh classes and vertex types from MDX in XNA Or a simple explanation on how to do it

Can i just lift the vertex type from MDX straight into XNA
