After about 10-15 minutes of gameplay, the audio slowly begins to become more and more distorted and fractured sounding. Both the sound FX and BGM gradually become more choppy and grainy sounding while dragging down the overall performance of the game. Any ideas

- Poor XNA performance or my poor code... or normal? Set your effect variables that don't change outside the draw method, then, change your draw method to something like this public void Draw(GameTime gameTime) { graphics.GraphicsDevice.Clear(Color.CornflowerBlue); foreach (ModelMesh mesh in CubeMesh.Model.Meshes) { BasicEffect effect = (BasicEffect)model.Effects[0]; foreach (CubeMesh cube in captureZoneSystem.capturePoints) { effect.DiffuseColor = cube.Color.ToVector3(); effect.World = Matrix.CreateScale(cube.Scaling) * Matrix.CreateTranslation(cube.Position) * Matrix.CreateRotationX(MathHelper.ToRadians(captureZoneSystem.XRotation)) * Matrix.CreateRotationY(MathHelper.ToRadians(captureZoneSystem.YRotation)); mesh.Draw(); } } } Tag: General Audio Disfunction

- 2D Pixel Perfect Collision Thanks, I'll check them out. Also, I didn't consider the implications of trying to collide sprites from the same texture sheet so I'll have to factor this in as well. Another thing I just realized is that the origin will have to be considered as it determines the draw offset when SpriteBatch.Draw is called. So that means Rotation, Scale, Origin and Offset(tilesheet location) Thanks for the help. Tag: General Audio Disfunction

- (Clip) Plane transform? Hi there Derek, thanks for the reply, I got it working using your vector4 approach ;) Somehow, the creation of a plane using the 3 points vector doesn't want to give the correct results. I have one more question: are you sure about the projectedPlaneCoefficients.Normalize(); line Ofcourse, the direction of the normal can be normalized, but generally if you apply the Normalize method to a Vector4, the w component is also affected. This w component is the distance from your origin perpendicular to the plane, so I think this should give problems. I think you only want the direction of the normal to be normalized.

- Dream Build Play Contest Question - Using languages other than C# Hi Catalin, I did read the DreamBuildPlay site, but my question still stands as .NET is supposed to be a cross-language API, I think it would make sense that they would also allow and accept non C# langauges to show off their XNA and .NET technologies.

- Xbox 360 D-pad issues Since XInput on the 360 and the PC should operate the same I don't see any reason why this shouldn't work. The DPad controls show up as 'buttons' in XInput so I don't see why they can't be down at the same time. Are you using C++/XInput or XNA Framework Which dance mat at you using You might also take this over to creators.xna.com if you are using the XNA framework. Tag: General Audio Disfunction

- [XNA] different textures on different polygons Thanks for your answer. But now if want to use ModelMeshPart type, i need to create a new model. But how can do this without the classical "content.load<model>" because it's a file type created by me. So i have currently one vertex buffer and one index buffer and i want to use them to initialize a new instance of Model class. How can i do Thanks Tag: General Audio Disfunction

- Model Exporting From Maya (.fbx) I am new to working with XNA, and this isn't exactly a response to your question, but I know that the .x exporter for Maya works rather well. I had to develop some SAS compliant shaders for viewing in DXViewer. I used the .x converter in Maya so I could make some more interesting models to look at. If I happen to work with the fbx format exporter for Maya, I will make sure to let you know what I find. I'm sure that will happen in the next few weeks. Take care, -Burton Tag: General Audio Disfunction

- How can I get XNA to draw stuff faceted? Ey up Here's a very dirty way to do what (I think) you want : 1. First draw the mesh solid, using a shader which outputs just black (you can probably do this with basic effect by setting diffuse to black or something, can't tell you off the top of my head though) 2. Next draw the mesh again as wireframe, using a shader which outputs just yellow, and probably mess with RenderState.SlopeScaleDepthBias and/or RenderState.DepthBias to bring the wireframe slightly closer to the camera Here's a better way : 1. Bevel the model's edges in your 3d app of choice 2. Apply different materials to the main faces and the bevelled edges And another way : 1. Parse the original model's verts and indices and recreate a new model with 2 extra faces for each edge and nice junctions at the corners 2. Render the new faces differently from the original ones I guess it depends what look you're going for. Is this a debug thing Or a Tron-style effect Cheers... Tag: General Audio Disfunction

- Help on some shader issues I'm aware that palleted textures aren't the best way of doing things or even a good way of doing things this days, the deal is that I'm stuck to using 16-bit color textures with 8-bit palletes (2 pallete indexes per texture color), that is the constraint. So I was trying to pass all the work to the gpu since I though that the .NET framework would do things like that pretty slow even on fast computers. I'll see if I can come up with something. BTW thanks for pointing out the point sampling issue, that would've had my head spinning otherwise. Again, if someone has any ideas no matter how crazy they are, please share.

- Getting the Model width and height The BoundingSphere class already mentioned will give you a basic idea of the overall size of a Mesh (or the entire Model if you Merge the BoundingSpheres for each Mesh). The left most point is BoundingSphere.Center.X - BoundingSphere.Radius, right most BoundingSphere.Center.X + BoundingSphere.Radius, etc. This is just an approximation: the spheres don't work well on non-spherical objects. There is a tutorial on www.riemers.net (in the forums, I believe) about creating a new Model class that will allow you to read the Model indices directly. Or, you could wait until the April/May XNA update which will provide updated access to the Mesh. Just some ideas... hope they help. Tag: General Audio Disfunction

- Stuttering in D3D application We are not loading or unloading any resources during the time that the hickups occur. Your second suggestion seems somewhat more likely, but still unlikely, because I'm running this on a 128 MB video card, and NvPerfHud4 reports a usage of about 25 MB video memory.

Now, could I ask you a brief question on how you would do this certain thing Let's say I had a text file, with 50 lines, each line containing the path/filename of a certain model/texture I want to load. This file can be changed by the user at any point while the program is not running.

- Cross-platform development question Most XNA code will work without changes on either platform, there are some exceptions like if you want mouse support on the PC, that code will need to have #if blocks around it or it needs to be in a PC-specific file, and there are some differences with point sprites. There are probably others as well but those are the major oes I've heard about. And of course you will want to avoid using any .Net Framework classes that are not implemented in the XBOX version of the .Net Framework. Bill Tag: General Audio Disfunction

- HLSL shader(s) using CPU instead of GPU I am using D3DXCreateEffect to create a vertex and pixel shader HLSL effect. The process I use to create and activate the effect is the same every time, I am only changing the pixel shader code, and here's what happens: My program renders about 50 fps generally with CPU usage around 4% and when I do a trivial RGB to BGR color swap with the following shader, this usage remains: PS_OUTPUT RenderScenePS( VS_OUTPUT In ) { PS_OUTPUT Output; // Lookup mesh texture and modulate it with diffuse Output.RGBColor = tex2D(MeshTextureSampler, In.TextureUV) * In.Diffuse; float r = Output.RGBColor.r; Output.RGBColor.r = Output.RGBColor.b; Output.RGBColor.b = r; return Output; } So with this shader the rendering does a dynamic RGB to BGR swap entirely on the GPU I figure, because the CPU usage is still around only 4%. Now I just change the shader, nothing else in any of the code anywhere, to this: PS_OUTPUT RenderScenePS( VS_OUTPUT In ) { PS_OUTPUT Output; // Lookup mesh texture and modulate it with diffuse Output.RGBColor = tex2D(MeshTextureSampler, In.TextureUV) * In.Diffuse; // Demo: 4-bit grayscale float avg = (Output.RGBColor.r + Output.RGBColor.g + Output.RGBColor.b) / 3.0f; avg = round(avg*16.0f) / 16.0f; Output.RGBColor.r = avg; Output.RGBColor.g = avg; Output.RGBColor.b = avg; return Output; } To me this seems simple enough but for reason my CPU usage goes way up when this shader is running (and the system lags like crazy). The rendering shows the grayscale image, so it is working, but the CPU usage is off the charts. I thought shaders were supposed to execute entirely on the GPU so I'm confused how it's possible that my CPU usage is going up unless something needs to be emulated in software. In my D3DXCreateEffect call I have the D3DXSHADER_NO_PRESHADER flag, (along with the not cloneable flag) which seems to be the only CPU-related flag available. My video card should be more than capable of such a shader even though it's not an ultra-powerful card (NVIDIA GeForceFX 5200).

- problems with sprites hello I am trying to make a weapon system on my first xna game. I was wondering if anyone could help me with a problem I have. Im using the XNA "How to" examples to try and render a simple texture as a sprite. I managed to use the first "how to render a sprite" example to render a sprite. the problem is, but i want to be able to position my sprite where I want so I used the second "How to" example. so I read through the tutorial and got the code in my game but when I run, I get an error saying my texture is being called as a texture2D instead of an AnimatedTexture(the code is made for an animated texture) so i guesss my texture is not animated.. but I dont want an animated texture! I just want a simple one and I just cant work out how to do it.. I found this other tutorial that seemed good but included this weird camera that can be rotated around the sprite... the camera code was buggy and didnt let my code run.. all I want is to know how to render a sprite at a given location and be able to change the variable to move it around. So Iv been fiddling around aimless, not knowing what Im doing trying to get this sprite to appear. Once I get this sprite rendered I think I might be able to work out a way to get it moving like a rocket or something. anyway this is my code , can somebody please help me, or maybe point me to a good tutorial. at this point in time Im getting an error saying Error 1 'Microsoft.Xna.Framework.Vector3' does not contain a definition for 'ViewMatrix' C:\Documents and Settings\something \My Documents\Visual Studio 2005\Projects\WindowsGame3\WindowsGame3\Game1.cs 133 45 Spaceshooter this is my code (i know its very messy and some parts are completely useless but hey Im new and Im experimenting with anything I can find, also iv commented a lot of stuff out because I experiment but I dont want to loose the original working partts of the code so I comment them out, add the new code and see how it goes).

I do call audioengine.update in the update method. Audio works perfectly fine for a while. What coding issue would cause audio problems to occur over a period of time
Re: General Audio Disfunction
Fluxtah
might be an idea to post your code that deals with the playing of audio, XNA is very new so its highly likely no one has experienced the problems you describe.
Re: General Audio Disfunction
dagfari
my code for audio is pretty straight forward. My general routine for calling sound FX is;
1) call 'cue stop' in case the effect is still playing
2) call 'get cue' to retrieve the sound again
3) call play
I do this in most cases where I only want one instance of the effect occuring at a time and there is a chance the sound will not have finished playing before it needs to be played again like in the case of a rapid fire weapon.
Re: General Audio Disfunction

I had this problem once, and when I called the Play method that doesn't require a previous GetCue() it worked fine.

1) When the bug happens, break into the debugger and check what your code is doing. It's possible that your game is starving XACT by doing a lot of computation on other threads.
2) Try to verify that your audio engine's Update method is actually being called frequently. Maybe add a counter and print out a debug message every 60 times that Update is called, or something like that.
3) When the problem happens, use the "Task Manager" to see what your CPU usage is. If the problem is related to XACT having too much work to do, then you'll typically see a high CPU usage (one hardware thread maxed out.) If you don't see a high CPU usage, then it's possible that you've got some other problem.
4) See if you can cause the problem to repro sooner by giving XACT more work to do -- change your game code to fire off 10 sound effects each time, rather than just one.
5) Create a repro case you can file a bug report for. If you want the bug fixed, the easiest way to get the XNA team to help you is to have an automatic, or nearly automatic repro case. When I had a similar problem, I added an event recording and playback system to my game, so that I could record 10 minutes of gameplay manually, and then automatically repro it.
Once you have your repro case, either pack it into a 2 MB ZIP file (the max size for a Connect bug report), or figure out how to post it on a web site some where. Then follow the bug reporting instructions on the "Frequently Asked Questions" portion of the XNA Game Studio Express online docs.

Yeah, I'll try to narrow down on it. By the way, this is all happening on Xbox360.

Any update on your problem
I've fiddled with XACT for the first time these last days, and I'm having a similar issue (windows only, since I have no xbox360). The distortion happens right away. I am using a rather large wav file (around 20 megs - as a side note, it is a playback recording of a 50k MOD file, heh).
As soon as I put comments on audioengine.update() 's method in the game's update method, the problem goes away and the playback is smooth.

It seems to be working ok for me but it's hard to test. I did simplify things a bit by not making every sound a Cue object. I only make Cue objects when I need control over the sound such as stopping it in the middle of playback. Otherwise I simply use PlayCue.

I had a similar problem when using cue objects. It seems it's a garbage collection issue - the cue object gets garbage collected while the cue is still playing - so the sound stops at random points. PlayCue() doesn't have these problems.
