    - Newbie question - spawning new objects For the timing, create a variable in the game class (say int _elapsedGameTime), set it to 0 in the Initialize event, and check in the Update event: _elapsedGameTime += gameTime.ElapsedGameTime.Seconds; if (_elapsedGameTime >= 10) { //spawn new ball //reset the variable _elapsedGameTime } Tag: XNA Game Studio Express Processor Parameters Game Technologies: DirectX, XNA, XACT, etc.

    - Load/UnloadGraphicsContent You cannot create content before the graphicsdevice is actually created. Once the device is created, you can create assets at any time. However: 1) If you cache the graphics device value, you have to re-cache this after the device is re-created in some circumstances. 2) If content is loaded when the device is in a lost state, you may already have gotten the unload call, but not the balancing load call. What I do, is check the GraphicsDeviceState, and only actually create content if it's in "Normal" state. After the device is created, unload(false) followed by load(false) will be called if the device is lost, such as when changing screen resolution. Unload(true) followed by load(true) will be called if the user drags the window to another monitor, so that the graphics device needs to be re-created. It also has to be called if there's an internal bug in the reset handling of the graphics driver -- the proper work-around is to tear down the device, and re-create it, but I don't know if XNA actually implements this. Because Load and Unload can be called "at any time" (although after unload, load is called before draw), it's not a good idea to create the game-level entities in these functions. Instead, create the game-level entities somewhere else, and make them load/unload their graphical resources as needed in those functions.

    - XNA vs Intel 915G I think the safe answer to this is no it does not. I have a laptop that has the Intel 945, which should be a generation or 2 ahead of the 915. This laptop - for being as powerful as it is can't run City Life, Ceasar 4, or age of empires 3. Age of empires 3 actually will run, while the others crash, however all of the triangles are flying all over the screen. Suffice to say I've not found a single game that uses pixel shaders that will run on this laptop. So I'm sure you can guess where I'd place my bets.

    - Problems to Create a Vertex Buffer... Anybody, HELP...? Hi, ... ... ... Well, you see... m_pVertexBuffer is an LPDIRECT3DVERTEXBUFFER stuff ... and shithappens which is the structure of the vertexes is an SIMPLE_VERTEX stuff ... So now, where do I point the pointer to... #define D3DFVF_SIMPLEVERTEX (D3DFVF_XYZRHW | D3DFVF_DIFFUSE) struct SIMPLE_VERTEX { float x, y, z, rhw; DWORD color; }; #define NUM_VERTICES 1000 #define RANDOM_NUMBER ( float )rand() / ( float )RAND_MAX LPDIRECT3DVERTEXBUFFER8 m_pVertexBuffer = NULL ; SIMPLE_VERTEX shithappens ; BOOL CVertexApplication::CreateVertexBuffer() { if (FAILED(m_pD3DDevice->CreateVertexBuffer( NUM_VERTICES * sizeof (SIMPLE_VERTEX), NULL, NULL, D3DPOOL_DEFAULT, &shithappens ))) return FALSE; m_pD3DDevice->SetVertexShader(D3DFVF_SIMPLEVERTEX); m_pD3DDevice->SetStreamSource(0, m_pVertexBuffer, sizeof (SIMPLE_VERTEX)); return TRUE; } _________So, first I tried this, but it didn't work...

    - Managed DirectX reference for C# project If I install a project from "DirectX Sample Browser" the references for DirectX (december 2006) are like this: C:\WINDOWS\assembly\GAC\Microsoft.DirectX\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.dll But this folder path don't exist, exist only until C:\WINDOWS\assembly where I found all library, DirectX too. If inside Visual Studio I click "Add Reference" I find only folder path like this C:\WINDOWS\Microsoft.NET\DirectX for Managed Code\1.0.2902.0\Microsoft.DirectX.dll and this folder path exist. Both version of dll work very well on my PC, but the second don't work if i try it on other computer. Don't work the exe and don't work if I open project too: wrong reference. SDK is installed also on second computer (always december 2006). Now the question. How can I add reference to right DLL (without using "DirectX Sample Browser" projects) that will work on any computer with right runtime installed From "Add Reference" I don't see the path C:\WINDOWS\assembly\GAC\... for dll. Thank you for help. Bye Toni Tag: XNA Game Studio Express Processor Parameters Game Technologies: DirectX, XNA, XACT, etc.

    - Use of professional 3d Game Engines with XNA - Port Thanks for your answer. An other Question Is the the Torque Engine already a C# Engine In some Thread there are User taking about starting with the Torque Engine until the Torque X Version is released. There they say that i would be no big deal to port the standard torque Content and Code to the Torque x Pipeline. What are the cost with Torque and when will the torque x be released Our game is just realisable with a real 3d game engine, Someone of you outhere allready know the content pipeline of Torque or Torque X What exporter are included (max maya ) what is the pipe with animations and are there some overall specialities If theres someone out there how has allready realised a project with the Torque engine it would be nice if you contact me at : ce@project-barcode.com thanks a lot have fun - creating games Tag: XNA Game Studio Express Processor Parameters Game Technologies: DirectX, XNA, XACT, etc.

    - HLSL design and compiler cleverness I have a good amount of shaders/fx files where all have several techniques for various shader level and detail implementations. In a worst case scenario this leads to a lot of similar code being represented in the various vertex and pixel shaders I use, which is really a maintenance hell if left like that. Change code in one place and 5+ other places need the same change. So this leads me to the following idea: Split the code into various functions and place them in suitable include files. Include the needed files for a given shader and call the functions. A few examples of such functions: translatePosition(), getSpecular(), getDiffuse(), getNormalMapSpecular() getShadowValue() and so on. Doing this would mean one task only exists in one file and only one function, which would make it very maintainable. However, as with normal code having excess amount of function calls leads to a certain amount of overhead. My questions are then: Since shader efficiency is important to maintain a highest possible frame rate, especially in pixel shaders, will doing this make my shaders slower, even if more maintainable Is there a way to force inline behavior of such code or does the compiler perhaps already handle that If the compiled shader will suffer a slowdown, does there exist any statistic as to how much, or does anyone have any experience with this themselves /Thomas Lindquist Tag: XNA Game Studio Express Processor Parameters Game Technologies: DirectX, XNA, XACT, etc.

    - Grouping units like in a RTS game Shouldn't be a problem, it's just a question of implementation. XNA can certainly handle cursor location, mouse clicks and dragging. It's up to you to draw the box and figure out what objects are within in. Then its just a matter of assigning orders to those units. (I assume this is for a RTS game ) Tag: XNA Game Studio Express Processor Parameters Game Technologies: DirectX, XNA, XACT, etc.

    - Material vs Shader I should have mentioned I have no problems understanding HLSL, that was not my question. Maybe the original usage of Material is out of place with current technologies used to describe properties of a surface (shaders do this), this is my idea of material: Glass Wood Concrete Rock Stone Clay Carpet Paper Plastic Plant Metal Cloth Fluid This is the dictionary definition of material: the substance or substances of which a thing is made or composed: Stone is a durable material. The original D3D Material, in my mind is out of place with shaders, maybe LightingProperties would have been more suitable, because a material is so much more than how a surface deals with light, surely Tag: XNA Game Studio Express Processor Parameters Game Technologies: DirectX, XNA, XACT, etc.

    - Custom Content Processor - Usage Rick, Thanks for your answer. In the days between posting and not getting a 'this is a good idea' / 'this is a bad idea' I went ahead and implemented it. It was painful down to the lack of good documentation on customising a content processor but with the kind help of serveral people I got it up and running. It now works really well, I can design my multi-level maps in my Windows map editor, import the xml file into my game and the content processor spits out a top level class containing all my levels and the code to render each level. I am now hooked on the content processor and my mind is spinning with possible custom processors You do mention that I can use the default importer for XML which is the bit I missed so I kind of do it myself but you live and learn Thanks again for your reply.

    - Bug in BoundingFrustum.Contains()? Hi, I know the box has zero volume, thats why i choose it as a test ;) What i thought would've happened is that a box with all corners being at (1,1,1) would be like the point (1,1,1) and so should still count as being contained within the Frustum just like the Vector at (1,1,1) is in the frustum. Is there any documentation explaining what counts as being "intersecting" or "disjoint" or "contained" I.e. is a box Contained or Intersectin if one of the boxes planes lies exactly on top of one of the Bounding Frustum planes but the rest are inside the Frustum I cant seem to find useful documentation on that kind of thing.

I am using a model processor to produce a path finding network. It is working quite well!

http://sharpx.blogspot.com/2007/01/first-steps-along-path.html

The green nodes are some offset away from the corners that were detected as significant to the path network. I would like that offset to be configurable; preferably as a property of the file in Visual Studio.

How do I provide custom parameters to a processor

Thanks,

Brandon Bloom

Re: XNA Game Studio Express Processor Parameters

Shawn Hargreaves - MSFT

User defined parameters on processors are something we'd like to do someday, but they didn't make it in for version 1.

The best workarounds I'm aware of are either to make your processor look up the value you want to tweak through a virtual property, so you can quickly make new processors that use different values by deriving from the first one and overriding just that one value, or alternatively to make your input data be an XML file that contains both the filename of the real asset you want to process, plus the parameters you want to use in that processing.

Ok, I'll hack something together :-)
