• Puzzled XNA/Xbox 360 memory management heads-up...

  I was just browsing through some docs on the 360's heap manager, and it turns out it is a compacting mark and sweep collector rather than the generational model used on the desktop... So... what's the deal regarding: Large block allocation (will it have a large object heap like the desktop version ) GC pauses times (do all threads halt during GC) Rico Mariani recommends a heap size equivalent to the Gen 0 size on the desktop, i.e. ~cache size. That seems way too small unless we are dumping lots of game data into unmanaged memory! Andy.

• akin_l DirectInput with Parallel Port Joystick

  How to create a DirectInput device connected to parallel port The parallel port uses the interface lpt-switch. thanks jpimentel, There is a complete sample in the SDK. The most recent version for this can be found here . If you download the SDK for Feb2007 there is also a solution in the ( SDK root )\Samples\C++\DirectInput\Joystick directory. Thanks. Cale This would really be up to the DirectInput driver. The driver needs to make the device appear to DirectInput.

• CalBob kW X-port for 3ds Max 9 (X file exporter with XNA support)

  I have made a preliminary version of the kW X-port plug-in available for Max 9. The full Max 9 download from Autodesk is almost 3 GB and is still going, so I haven't been able to test it yet -- it's just re-compiled with their new SDK. I give it a good 90% chance of working fine, though :-) The version for Max 8 has been tested, of course, and is still available. It might work as far back as Max 6, because they are apparently version compatible from 6 through 8, but I have only tested on 8. kW has some features that might help with XNA usage, such as support for the Max Direct3D9 material with shader parameters; support for mirroring along Z and mirroring the V coordinate ; support for properly exported skinned meshes even if ...Show All

• leonlai Custom ContentTypeReader

  Hi, I'm trying to make my own content loader for a custom font file. I've got the custom file to compile using an importer that I wrote, and I can see the XNB file is generated as expected, but the content manager can't seem to find my ContentTypeReader. Here's the writer: [ContentTypeWriter] public class GameFontWriter : ContentTypeWriter<GameFontStub> { protected override void Write(ContentWriter output, GameFontStub value) { output.Write("hello"); } public override string GetRuntimeReader(TargetPlatform targetPlatform) { return "Importers.GameFontStubReader"; } } The game compiles fine, but when it reaches the line: hudFont = content.Load<GameFontStub>("Fonts/main"); ...Show All

• WV John Geometry instancing support on 360?

  I'm working on a geometry instancing demo and I noticed in the XML documentation for GraphicsDevice.SetFrequency() that the method (and related methods) are "Windows Only". Is this a mistake That's interesting. It's the first time I've ever heard anything like that (about performance being hurt with geometry instancing). Do you have any online references of articles/tests I could read Here are the  NVidia thoughts: "Use of instancing isn’t free. There is a small amount of per instance overhead in the driver (luckily this is much less than normal draw calls). Also, since we are passing down extra instance data in the vertex stream, all the instance data adds to our vertex stride, which will reduce our ve ...Show All

• WestMike Torque X for XNA release

  Hi guys! Somebody know when Torque X will be released I think everyone in here is greatly anticipating this release. For now, it's fun just to get a good feel for the XNA framework. As long as it doesn't drag out too long.... any hopes to have it for free I dont know the specific answer, but their website says to: " Keep your eyes on this page for more information regarding release dates and pricing information." http://www.garagegames.com/products/torque/x/ That's probably a question best left for Garage Games. I don't think they have announced any pricing details yet. Mehdi Mahdloo wrote: any hopes to have it for free Well: 1. Garage games needs to make profit to pa ...Show All

• ralfkret Custom processor with additinal data - Content pipeline

  I understand one can use the Tag property to add custom data while processing a model. Is that the only way Meaning, do I have to create a whole hierarchy of user defined classes with the Tag property as a root I though of something like deriving ModelContent but that's sealed. Guess you are like the rest of us and just want to be able to read the vertex and index data from a model Hopefully they'll add it so that most of these issues don't need custom importers. Create a collision skin (other than the supplied bounding sphere), add hard points to attach weaponry or any other thing that would require processing of the original geometry or exporting custom data directly from the modeling tool. ...Show All

• Thanh Where's the XAP for spacewar?

  The sound project file. Is there one It seems all the sound content is locked up in SpaceWar.xgs, spacewar.xsb, and spacewar.xwb files. How do I load those to edi the sounds Can I load multiple sound, um, data files There's nothing to stop you opening as many soundbanks as you like.

• Roman S. New to this - Keyboard Input

  Hey guys. I'm pretty new to the C# language. I've downloaded XNA and I've been messing around trying to create a pong game. So far I've managed to get the two paddles on the screen along with a red ball. I want to add keyboard input to the two paddles (they are sprites). I've been looking around on how to add keyboard input, but the more I look, the more confused I get. If someone could help me that'd be great. Some other things I am in the dark about are how to make your window application a bigger size, and if there is a coordinate plane for the window application. I normally find myself just guessing coordinates for my sprites untill they are places where I want. Thanks. Thanks! I'll have to try that ...Show All
