    - Generating Grid With Loops I'm trying to create a grid for my program, but I can't get it to work. Right now it just draws real long lines instead of a nice grid. I understand the buffers, but I feel like I'm calculating either the vertices or indices incorrectly. Any ideas int numVerts = (size * 2) * (size * 2); int numVertsRoot = (size * 2); verts = new VertexPositionColor[numVerts]; int numIndices = numVerts * 2; indices = new short[numIndices]; int index = 0; for (int i = 0; i < numVertsRoot; i++) { for (int j = 0; j < numVertsRoot; j++) { verts[i * numVertsRoot + j] = new VertexPositionColor( new Vector3(i - size, 0, j - size), Color.White ); if (j > 0) { indices[index++] = (short)(i * numVertsRoot + j - 1); indices[index++] = (short)(i * numVertsRoot + j); } } } Tag: Need info about .X files

    - Global lighting This might seem silly but here goes.. is there a way to set the default lighting for all objects This is what im doing now..(taken after spacewars) Matrix m_view = Matrix.CreateLookAt(cameraPosition, Vector3.Zero, Vector3.Up); Matrix m_proj = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f), aspectRatio, 1.0f, 20000.0f); for (int i = 1; i < MAX_MODELS; i++) { foreach (ModelMesh mesh in Enemy .C_Model_m.Meshes) { //This is where the mesh orientation is set, as well as our camera and projection foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); //effect.LightingEnabled = false; effect.World = Enemy .C_Actor_m; effect.View = m_view; effect.Projection = m_proj; } //Draw the mesh, will use the effects set above. mesh.Draw(); } } When i do this my Frame rate takes a big hit... I narrowed the problem down to the line of code effect.EnableDefaultLighting();....... Its not so much the lighting, because if i shut the lighting off after this call i still get a crazy slow FPS. Is there anyway i can just EnableDefault lighting through out my game... so its not enableing it for every effect in every mesh of every model Thanks, -Wes Tag: Need info about .X files

    - Joysticks with XNA Before I start I already know that XNA has no joystick input support - but I'm using an xbox 360 styled joystick input with force feedback (so its exactly like the xbox 360 control) this is it: http://www.powerwave.com.au/index.php evnF=productImage&format=&title=Powerwave%20360%20Shape%20Controller%20-%20Carbon&id=2.195326&acode=APCPW2C3C And I want to know if anyone can help me get it working so when I debug a game in XNA I can use this controller I've bought instead of my keyboard. Or at least if anyone knows any software I can use that converts joystick input to keyboard so I can map the triggers on the controller to the keys that XNA uses. Thankyou for your time.

    - Terrain & Terrain-Physics (intersection, dynamic slicing) Hi, at the moment i am wondering how to deal correctly with a terrain in XNA. For now i just have a static terrain model loaded from file. So i have an object (a buggy for example) and want to get some physics on it, therefore i need to check for collision with the underlying terrain. The collision with the buggy could be done with a boundingbox, but the terrain needs to be checked per face (3 vertices triangle) i think. But i cant find a way to check this. I think iteration throught all faces of the terrain would take to long for all objects in the world. How do other developers solve this problem So if I do it this way i will always need to calculate every object in the world each frame, no mather if its visible or not, is this the correct way I really get crazy about this whole scenario and don't know what ways are right and wrong Also i am confused about slicing of the terrain, a big game world with hundret-thousands of vertices needs a slicing algorithm, but do i automaticly need a dynamic terrain based on a vertex array in XNA How else to slice an existing model Hopefully someone can help me out here Cu Thunder2002 Tag: Need info about .X files

    - texture moving on a vertext shader Hello Noobie question here for you. I'm copying the example from the help files in GSE (the example titled: How to create custom texture effects), and have managed to successfully port the cube into my game world (which is a hacked version of the top-down spaceship example that is right at the begining of the help files). I have changed the spaceship example to always keep the spaceship in the middle of the screen, so I can fly around asteroids that I have put into the game, and I've also managed to set a boundary to stop the spaceship flying off in one direction for ever. Now I want to adapt the custom texture effects code to stay in one place while my spaceship flies around it. I did this by updating the custom texture effect "world-view-projection" data with the view of the spaceship during the draw() function. This makes the cube stay in one place, but the texture on the cube moves with the spaceship. What I think is happening is that the tex2D part of the code is using the spaceship view to position the texture on the cube. So when the spaceship moves the texture moves around on the cube. Any idea how I can edit the custom texture "fx" file to seperate cube coords from texture coords Many thanks, SuperArmySoldier Here is the ReallySimpleTexture.fx code... uniform extern float4x4 WorldViewProj : WORLDVIEWPROJECTION; uniform extern texture UserTexture; struct VS_OUTPUT { float4 position : POSITION; float4 textureCoordinate : TEXCOORD0; }; sampler textureSampler = sampler_state { Texture = <UserTexture>; mipfilter = LINEAR; }; VS_OUTPUT Transform( float4 Position : POSITION, float4 TextureCoordinate : TEXCOORD0 ) { VS_OUTPUT Out = (VS_OUTPUT)0; Out.position = mul(Position, WorldViewProj); Out.textureCoordinate = TextureCoordinate; return Out; } float4 ApplyTexture(VS_OUTPUT vsout) : COLOR { return tex2D(textureSampler, vsout.textureCoordinate).rgba; } technique TransformAndTexture { pass P0 { vertexShader = compile vs_2_0 Transform(); pixelShader = compile ps_2_0 ApplyTexture(); } } Tag: Need info about .X files

    - Content Pipeline Alex: I would not use the MsBuild approach for what you describe, I would add the file to my project as well as all the textures and create a custom processor to write out the file names. Or your custom processor could process each file and write them as external references, meaning you would only have to add the 1 file describing all assets to your project. I am taking this approach for some of my objects that have metadata and assets attached with them. Tag: Need info about .X files

    - Animation sample An AnimationChannel contains a set of keyframes for a given bone. The name of the bone to which the channel corresponds is stored as the key for that channel in the AnimationContent.Channels property. A keyframe in the channel stores the non-absolute transform for the bone at a given time. If you want to get the absolute transform of the bone at that time, one way to do it is to set all the Transform matrices on the Model.Bones collection to your keyframe transforms, and then call the CopyAbsoluteTransformsTo method and have them copied to an array. But that just gives the absolute transforms and you still need to do more work to make your model display in a skinned aimation. The next step is to make an effect that uses (usually) a matrix palette to display the vertices properly for a skinned model. Then, you need to find out how the bone indices in the vertex buffer will map to the indices on the model. I'm not exactly sure how the default mapping works, but I think it is one of two possibilities (the first is that it is mapped directly to the indices in the bones of the model and the second is that it is mapped in the order that the bones containing skin weights appear in the hierarchy). I just overrode the default implementation and manually mapped them. Once you have resolved this, you can make your matrix array that will be passed to your shader as a matrix palette. Finally, vertices in the model are stored in the bind pose. In other words, if you were to just render all the vertices of a skinned model on a screen and not transform them by any bone matrices, the model would appear as it did when it was initially rigged in the modeling program. So, because of this, just passing the absolute bone transforms to the shader will not display the model properly. For the final step, you will need the matrix that transforms the vertices from the bind pose bone space to the local space of the bone. This can be found by multiplying the absolute mesh transform by the inverse absolute transform of the bone (when the model is originally loaded). This transform has been called a large number of different names by many different people (its "official" name is perhaps the inverse bind pose transform), but I just call it the skin transform. Finally, you can get the transform that you want to pass to the shader by multiplying the "skin transform" by the absolute bone transform for that frame. Edit: The one thing I forgot to mention is that the keyframes are not interpolated, so if you don't keyframe your animation to 60 fps in your modeling program, you probably also want to do that in the processor.

    - By the numbers - why so big? I would suggest doing a batch convert on all of your textures to DDS and use Dxt compression on them. Then you can use the passthru processor (At least thats what i've heard) and your file sizes should be nice and tidy. The content processing time will also be cut down to nothing.

    - The documentation needs seperation between PC and XBox 360 I'm trying really hard to enjoy XNA. It seems like a clean break from native programming. I enjoy the innovation that MS gave, but maybe its just their docs that are just annoying right now. I read the docs and when I try to follow something on the Windows development side, it goes right into the XBox code and doesn't give me the source code I need for Windows. I thought I was reading a Windows section too, or sometimes hoping that I am. I wish Microsoft could seperate the differences because right now its just "oh and while you're doing reading about what relates to Windows development here, take a look at the XBox code below." All I can say right now is the documentation needs some seperating. I'm do PC development and I have no care how machine #2 differs, especially when it only gives me machine #2's source code. Sure, its somewhat of a rant, but MS is on the right track, had deadlines and all which is reasonable, etc., but the documentation definitely needs some rearranging. It's like VB.NET and C# programming. They both do basically the same calls, but the details differ. The Visual Studio team recognized that and made a seperation between how VB.NET and C# did a task. I would suggest doing the same between the PC and XBox 360. I'm just not finding what I am looking for although it gives me the code for machine #2, but it doesn't even explain the difference for machine #1 almost half the time I look up something.

    - exporting x and fbx files Right - after much mucking about with exporters I thought I'd have another look at the code. If you want to screw up the face normals in a 3D model - simply do the following before your 3D code - spriteBatch.Begin(SpriteBlendMode.AlphaBlend); // Draw some 2D stuff here, possibly using the sample code - or draw nothing! spriteBatch.End; And try drawing your 3D models here - it all breaks! What!! ! How can this be If I send some 2D sprites down the pipeline, then render some 3D models, everything goes horribly wrong. Perhaps 2D sprites corrupt the z buffer, though I'm not sure how. I've tried it without SpriteBlendMode.AlphaBlend, but that makes no difference - and anyway, you need alpha for sprites. When I say "goes horribly wrong" - I mean faces appear through each other. Is there some vital process I've missed My display code is mostly from the various samples, and I've tracked it down to just those two lines anyway. For ages I've been assuming Max and Blender are exporting incorrectly, that face normals are broken but it appears to be something more esoteric. Cheers for any advice. Robin. "And Lo!

    - Using multiple passes in same technique Ultrahead wrote: ... Passes within a technique are not really intended to be used individually ... Well, unless you need to improve performance and thus, decide to avoid changing techniques -and consider a pass as a "different technique"- to gain some speed ... I very much doubt you'll see any perf gain from doing something like that. The reason changing effect technique costs is because this has to alter lots of renderstates on the graphics device. There is no difference in how much state has to change when you switch between two techniques, compared to two passes that change the same amount of state, so there isn't any huge performance difference between one and the other. The effect system is designed to use techniques to represent different ways of rendering an object, and passes to represent multiple draw calls that are needed to display a single object. I would very much recommend using it like this: trying to force passes to do what techniques were designed for is just going to cause hassle and not gain you anything useful.

    - 2D-3D Brawler help. Thanks! Yeah, I'd highly recommend 2D. I've done a lot of games in 2D and one in 3D and 2D is so much less frustrating to work with. I'll probably upload my source sooner or later, but it's a bit complicated, and not well documented at all. Basically, in a nutshell, you want to make lots of robust editors where you can define as much information outside the game engine as possible. I've got a character editor where you can place body parts to make up frames of animations, then define specific animations as being composed of certain durations of frames; also each frame can have a few script commands (for looping, making the character slide forward a bit, etc). I used to hardcode the script stuff, and believe me, it got ugly. That game has a character editor and a map editor; the map editor does little more than let you set ledges, which are sort of like mostly horizontal left-to-right polylines. And that's about as uninformative as crash courses get ;) . Tag: Need info about .X files

    - Fullscreen and multimon Hello community. First I appologise if this is the wrong forum to ask this question. I have signed up here hoping to find a community of D3D developers who could help me out a little while I learn the ropes. Anyway, I have a multimonitor setup where I am trying to create a fullscreen window on my secondary monitor. This is mainly for debug purposes but it would be great to enable this in my final product. I have no trouble creating the device, but when I start working on my primary screen the secondary loses focus, and with it loses the device. There is probably a really simple solution to this, but I have yet to find it. Also, when creating a fullscreen window, is it ordinary for for both screen to start flickering while the fullscreen device is being created I have a feeling this is related to my first problem. Regards. Tag: Need info about .X files

I am searching for more info about .x files I mean not those mesh
(model) files but files which can be created with help of templates

template my_struct

{

<xxxxxx-xxxx-xxx-xxxxxxxxxx>

STRING some_str;

}

For me most intresting thing is f.e can I use data types like bool int float or maybe even class data types

I gues I could findout this if have some articles to read. Now I have only one book which talks about it but unfortunately I assume that threre is much more about X files then just in that book.

I tryed google but no useful links.

SDK mhhh only methods/interfaces/structures etc. again not what i want :(

Does anyone know some tutorials/articles about it
