- Displaying Videoframes with DirectX As I've answered to someone else in that post , I would recommend to don't lock the back bugffer but rather to fill a texture (using the some lock/unlock technic) and then render that texture to the back buffer. This can seems quite similar to what you've done, but modifying the back buffer introduce a synchronization stage between the cpu and the gpu (during the lock). During that time only one of the component will be able to work : the cpu. So avoiding that has the advantage to keep cpu and gpu tasks parallel and thus get more performances. It can also allow to do some of the video format conversion in a pixel shader, wich can be a huge optimization in some cases. In the other post I gave you the link, I've explained a bit how to do and also speak about non square and/or non power of two texture sizes issues.. Tag: cloud of dust like in battlefield 2 : mc

- Hiding the minimize/maximize/close buttons UNTESTED!!!!!! Add a reference to system.windows.forms and then pop this code in System.Windows.Forms. Form f = (System.Windows.Forms. Form )System.Windows.Forms. Form .FromHandle( this .Window.Handle); The you *should* be able to adjust about anything you can with a form class. I cant stress enough I havent tested this yet, nor do I know if its even recommended. Obviously this will only work on Windows too........ N EDIT Just added it to my code and it compiles and runs fine. The returned value IS a window but I havent tried chaging any proprties of it yet. EDIT 2 Removed the minimise box fine using f.MinimizeBox = false ; so I know it works here, but again, I dont know if its a recommended way of doing things........

- Help on some shader issues The simple answer to your problem is to use a 1 byte per colour format like D3DFMT_L8 for your texture. Unfortunately, doing a palette lookup like this in a pixel shader may not produce the results you're expecting. You'll need to disable filtering (ie. use point sampling) otherwise your texture's index values will get interpolated before being sent to the pixel shader. If you want filtering you'll need to do it yourself in the shader. As for the complexity of colour indexed textures, video card manufactures actually dropped support for them because they were too expensive, in terms of space on the chip, to implement. You should consider whether it's possible for you to use one of the DXTn compressed texture formats (eg. D3DFMT_DXT1 ) instead. Tag: cloud of dust like in battlefield 2 : mc

- Stuttering in D3D application Most often stuttering is caused by dynamic creation of resources during gameplay. Other reason can be that you allocated more resources than total size of video memory and occasionally Direct3D runtime will swap textures in/out of video memory.

- Content Pipeline All of your content will need to be pre-processed. You can load any of the processed content at runtime, for example if you had 10 models you could add them to a combo box and let the user pick the one they want. You can do this dynamically too, but you have to create an MsBuild document and run MsBuild on that document file telling it what to do, there are examples of this on the forum. Several people wanted this to make editors. This would be suitable for that purpose, but not for a real-time game (too time consuming). Tag: cloud of dust like in battlefield 2 : mc

- Xbox 360 Hardware limits There are 3 cores, each of which is hyper-threaded, so there are 6 hardware threads. Of those, the XNA runtime has chosen to reserve 2, so you get 4 hardware threads for yourself. It appears that you get one thread for core 0, 1 thread from core 1, and both threads from core 2. The Xbox has 512 MB of RAM, which is shared between graphics, sound, game state, etc. Managed resources don't necessarily need to be duplicated in memory, though, because there's no risk of device loss/reset. You can do the math yourself based on that. (I would assume that some amount of space is used by the XNA framework, too -- say 32 MB for a conservative estimate) If you really want to know, you could create a linked list, and add class instances size 4000 bytes successively to that list, until you run out of memory. Count how many you could create before the exception. Tag: cloud of dust like in battlefield 2 : mc

- HLSL shader(s) using CPU instead of GPU It can't switch to using the CPU in the way you seem to suggest - that would require you to pull down your device and recreate it with the reference rasterizer. Vertex processing can run on the CPU but not pixel processing. That said, I don't know why you'd see this characteristic - but I'd hazard a guess it isn't directly the shader you're using. More likely the change has caused a bottleneck somewhere, or you're starting to see more draw-call overhead (etc..) Stepping through your frame in PIX and doing some decent profiling might help you find the true reason for the performance difference. hth Jack Tag: cloud of dust like in battlefield 2 : mc

- New XNA Game: Warriors of the Shining Star. Looks good. A few comments: Need to scan over the text a little. Found a couple typos (secure, sergeant, etc.) I think the enemies need to be a different color than blue. They look too much like the main character. The effects look great. I see that your next build is going to focus on making it look nice and I think thats good because it appears you have all of the hard work (AI, pathing, effects, game design stuff) done pretty well. The movies run really fast for me, so I'm guessing that's not the actual game speed. :) I've visited your site a few times recently (don't remember how I got there), but I remembered the previous movies. On the personal side, I enjoy reading about the problems that you ran into during your game dev on your blog. So when I finally get time to finish/work on my game, I'll know what to do or not to do :) Once you get the game ready for release, don't forget to submit it to sites like http://www.xnagamereviews.com.

- loading textures on array I think I have it right.... you want to have an array of textures loaded, here is a simple method that I am using. Declare your array under the main dec' for the contant manager private Texture2d[] textureArray; then when loading the content trough the pipline... this.textureArray = new Texture2d[5]; this.textureArray[0] = content.load<Texture2d>("Ball_01"); this.textureArray[1] = content.load<Texture2d>("Ball_02"); this.textureArray[2] = content.load<Texture2d>("Ball_03"); this.textureArray[3] = content.load<Texture2d>("Ball_04"); this.textureArray[4] = content.load<Texture2d>("Ball_05"); Hope it helps.

- XNA's use of Collections Use a simple for() loop to do the work of your collection set. Eg: LinkedList<Type> myLL = new LinkedList<Type>(); // add a bunch of things of Type to the collection... for(int nLoop = 0; nLoop < myLL.Count; x++) { LinkedListNode<Type> cur = myLL[nLoop]; Type curType = cur.Value; // Manipulate curType here } That same code could be turned into a foreach() call ( eg: foreach(Type curType in myLL) ), but as you said this generates some overhead which needs to be managed by the GC. You could also use a while() loop to do the same thing using the ability of the LinkedListNode<> class to traverse the list. While I am using a LinkedList here, the same general principle works on any of your mentioned collection sets. Anything with the array sub-script overloaded can be done with a for() or while() loop. Try using one of those methods instead. Tag: cloud of dust like in battlefield 2 : mc

- The future of 3D grahics programming with managed code (Microsoft technology) Do you have the URL Hard to argue with an article I can't see. >Microsoft(MS) will stop the developoment of DirectX with the managed code Unlikely since XNA was launched 2 months ago. However I do agree that there is little published about Microsofts future plans for managed APIs. We don't know if the MDX style API is dead and XNA is the only future, we have heard nothing about DX10. Here is similar responses I have posted recently http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1274507 and http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1273547 But if OpenGLs vision of the future is more compatibile with your goals then its a valid alternative.

- .xnb files are huge Maybe I need to explain myself better. When the background images are stored as compressed jpg's they are about 75 KB in size for at 1280x720 resolution.

- Is my normal code wrong? Some tips: It looks like you are trying to average the normals to create smooth shading. Can you do "flat" calculations first, to try to see if it is your normal calculation that is wrong, or if it's bad data (pulling the wrong triangles to average, etc) Make sure your triangles have the same winding (when you pull in the invidivual vertices) Try using the Plane constructor that takes 3 vectors. You can then use Plane.Normal for the results. Tag: cloud of dust like in battlefield 2 : mc

- Meshes, Material and Light dga wrote: Problems: First big problem is the lighting that takes place through the shader. It seems like the lighting is done for every "Mesh" (Net, Ads, Floor) again. Its hard to explain. But as you can see in this Screenshot the floor is lightened in the TopRight corner, but the ad there is very dark. Same for here . You can also see another "specular" on the net besides the one on the bottom left. When i move the light and the floor is getting dark, you see best, that every add got its OWN lighting. Look here . So my questions is, what am i doing wrong Is it because the whole playground is ONE model Do i have to draw the models seperate..floor, net, ads My feeling is just, that the lightning is done on every "object" and not for the whole "scene". If i would draw the model seperate wouldn't i become the same problem, because every seperate model is now lightened seperate Hope you can help me with this explanation. I think there is something i have misunderstood in the basics of working with shaders. Difficult to tell from those pictures. Try using a single blank texture for everything so that you're not being fooled by the texture - difficult to compare a black surface with a white and a blue one. It could be your shader, it could be the normals on the meshes, it could be many things. dga wrote: Whats going on with the floor texture. It looks like mirrored. AdressU/V in the TextureSampler (shader) is set to "Wrap". When i set it to "Clamp" the outside of the field is gray, but it should be blue. Well there is no texture for that blue, but a MaterialColor and my shader is just getting the "diffuseTexture" of the current meshpart. So is something wrong here Clamping a texture will make everything outside of 0.0 to 1.0 in your UV coordinates be the colour of the texture's border (I'd guess gray in your case). You could have a border around the texture that is the same blue as the inner parts of your texture, or you could split the mesh so that you only texture the middle of the playing court with lines and the outside is untextured or plain blue texture. Hope that gives you a little more to go on. Cheers, Leaf. Tag: cloud of dust like in battlefield 2 : mc

- Could C# be the future of gaming? For now, at least, no; C# as well as Managed DirectX still have a hurdles to get over (IMO). The language is still relatively new, developers are still learning the ins and outs and how to push applications developed in C# to the limit. In my opinion, although I love C# and swear by it, the professional community is and will be very reluctant to drop C++ for a newcomer such as C#, especially considering its lack of cross platform abilities.

I played BF2 on a ps2 a good number of months ago so I'll admit that my memory is a bit foggy (yes, that was a pun). But if I'm not mistaken, the effect you're talking about is the smoke grenades right
When I played it, I seem to remember them just being a particle system with big sprites. With the alpha blending, it did a good job of partially obscuring the other players in the smoke ... a sniper with a straight shot could still pick them off, but it wasn't easy.
Is that what you were referring to

A truely volumetric effect would be overkill for something like smoke behind a car (or fire, for that matter). I remember volumetric fire from Quake II - It looked like a horrible solid explosion. I used to throw grenades just to watch the explosion geometry animate.

Now that I look at the *correct* photo you're pointing out I think it's pretty clear to see in the foreground where the billboard-ed sprites are intersecting with the terrain. It may be an advanced sprite system (it does look good) but the intersections do give it away.

Maybe you can use impostors and/or spherical volumetric billboards.
