    - Realtime debugging seems to make game progressively slower... Hi, When I am running my game on the 360 via the solution on my pc it just gets gradually slower and slower until it almost grinds to a halt. It doesn't exhibit this behavior on the pc solution and they are using all shared components so the code is identical. It seems ok when I run it without debugging. Any ideas Tag: XNA Game Studio Express Protection level to high Game Technologies: DirectX, XNA, XACT, etc.

    - Can't deploy to Xbox 360 from GSE I have had to fix deploy issues for a few friends now and without fail it has been one of three things 1. incorrect creators club code entered into xna game studio. 2. not starting the 360 xna launcher first before attepting to deploy their game. 3. Selecting the windows version of a project and then wondering why building it does not deploy anything to the 360. I also noted that not one of my friends said thanks once the problem was pointed out to them. Embarrased at the error I guess.

    - Problems binding a texture to a sampler (InvalidCastException) I'm trying to do something as simple as setting a sampler2D parameter in the effect to a Texture2D object loaded by the content manager, like this: tex = content.Load<Texture2D>("assetname"); For importer and processor for 'assetname' i use Texture - XNA Framework and Texture (mipmapped) XNA Framework, respectively. The loading works fine, but when i try to bind it to the sampler, like this: effect.Parameters["tex"].SetValue(tex); i get an InvalidCastException . This happens no matter what importer/processor i try in whatever combination, and no matter if i change the type and Load<> parameter to Texture instead of Texture2D. 'tex' is the correct name of the sampler2D in the shader, and i don't think i've messed up anything else in particular. Googling this issue gets me about zero relevant hits. Any ideas what might be wrong Tag: XNA Game Studio Express Protection level to high Game Technologies: DirectX, XNA, XACT, etc.

    - Rotation help Hi: Your question sounds like a problem I had to solve that simulates orbiting the Earth along an equitorial orbit inclined 28.5 degrees (and a polar orbit too), while simulating the Earth rotating throughout its day. I used a combination of Matrix.CreateRotationY to simulating the satellite's orbit around the planet, and Quaternion.CreateFromRotationMatrix (passing in the rotation matrix from Matrix.CreateRotationY) to simulate Earth rotating about its own axis. If you're interested, check out my Earth Orbit Demo at http://www.spellflight.com/GameModels/EarthOrbitDemo.zip and look at Planet.cs' Render function to see how I did it. Hope this helps.

    - Spacewar .fbx models. So far my complaint with their models isn't the complexity but the sheer size of them. For my game I had to write a custom processor that scaled them down by .01 to even start to get the size I would need. I guess, though, for SpaceWars, the large models were fine and allowed high detail, so it does make some sense for them.

    - Stream Output after VS Direct3D10 documentation states that: " The purpose of the SO stage is to write vertex data streamed out of the GS stage (or the VS stage if the GS stage is inactive)..." Does this indicate we can stream out of the vertex shader There is no CreateGeometryShaderWithStreamOutput- like function to create a VS with SO, and if you disable the GS with SO buffers bound, all you get is a bunch of d3d warnings stating the buffers are redundant. Is there some other way to stream out of VS somehow Thank you. Tag: XNA Game Studio Express Protection level to high Game Technologies: DirectX, XNA, XACT, etc.

    - Plane constructor values question Hello all. When creating a new plane object (for collision detection) I am curious as to the values used for the Plane(x,y,z,d) constructor. If for instance I wanted a plane located at 0,0,0 and is pointing straight up (+Y ), what would the correct values be for the constructor The d component I ASSUME(probably wrong) is the distance from world 0,0,0. If say the plane is rotated 90 degrees on the Z axis so that it runs up and down the world Y axis, what does that constructor look like I'm just not sure what the values should be specified in. World units, radians, degrees There isn't much of an explanation in the documentation and I'm sure this is probably trivial knowledge to most of you but I could use a little nudge in the right direction. Thanks so much for your time. Dan Tag: XNA Game Studio Express Protection level to high Game Technologies: DirectX, XNA, XACT, etc.

    - 3d collision detecting with level I was just wondering has this is done usally (collision detection with the 3d game level).

    - Effect file parameters Actually sorry I did not look at it to well I thought it was just the worldviewprojection but it seems its working on the other input matrices also: vertexOutput mainVS(appdata IN) { vertexOutput OUT; half4 normal = normalize(IN.Normal); OUT.WorldNormal = mul(normal, WorldIT).xyz; half4 Po = half4(IN.Position.xyz,1); half3 Pw = mul(Po, World).xyz; OUT.LightVec = normalize(LightPos - Pw); OUT.TexCoord = IN.UV; OUT.WorldView = normalize(ViewI[3].xyz - Pw); OUT.HPosition = mul(Po, WorldViewProj); return OUT; } Looks like it needs all of these set: half4x4 WorldIT : WorldInverseTranspose < string UIWidget="None"; >; half4x4 WorldViewProj : WorldViewProjection < string UIWidget="None"; >; half4x4 World : World < string UIWidget="None"; >; half4x4 ViewI : ViewInverse < string UIWidget="None"; >; I am not an expert at HLSL but I do use them and code my own 'basic' shaders, so I am not the best person to help, but I tried :) Tag: XNA Game Studio Express Protection level to high Game Technologies: DirectX, XNA, XACT, etc.

    - How to associate material info with a ModelMeshPart? So each set of polys in a Model with a common material becomes a ModelMeshPart once you load it into the game. What I can't figure out is how you determine which material got associated with which ModelMeshPart. There don't seem to be any public members of ModelMeshPart that tell you the name of that part, or any way to somehow implant your own "blind" data (to use Maya's terminology) and then read it back. Here is why I want to do this: Say I've got a spaceship model, like in the Spacewar demo. I want the cockpit to have a separate material with completely different properties than the rest of the ship (textures, specular settings, etc.) The SpaceWar demo gets around this with its 2 reflection maps by hard-coding the index of the ModelMeshPart that uses it second, different map, then assigning the different map once the draw loop gets to that index. Aside from the fact that it's a patently terrible way of doing things, I don't want to use that method because it would require me to figure out what index the exporter assigned to each material . . . and I may very well end up with hundreds of Model objects to have to read through by hand just to get the index. I also thought of simply skipping ModelMeshParts altogether and having the cockpit be a completely separate ModelMesh. What is the real way to do this Thanks, Tom Tag: XNA Game Studio Express Protection level to high Game Technologies: DirectX, XNA, XACT, etc.

    - RenderDarget2D() exception Hi. I have a problem launching my game on friends computer - "Report problem" dialog appears... I gave him source to compile himself. Now i know, that line: glowMaskTarget = new RenderTarget2D(graphics.GraphicsDevice, graphics.GraphicsDevice.PresentationParameters.BackBufferWidth, graphics.GraphicsDevice.PresentationParameters.BackBufferHeight, 0, graphics.GraphicsDevice.PresentationParameters.BackBufferFormat); ...throws an exception with no helpful information. Code is in LoadGraphicsContent method as automatic content. I got GF 6200 card, and that game runs on one friends of mine computer with same card as well, but in this case, with GF FX5200 - it throws an exception. What device cap could it be Are there some specific tricks to walk-around this Thanks. Tag: XNA Game Studio Express Protection level to high Game Technologies: DirectX, XNA, XACT, etc.

    - Drawing a 3d model with shader effects It could just be that I am a complete and total idiot but I have been looking for an easy way to draw a 3d model with shader effects (.fx file). I had orignally guessed it would be easy becuase of the Tutorial 1: Displaying a 3D model on the screen, but that uses basic effects, not an effects file. Can someone please show me a simple way of doing this because I am evidently too dumb to figure it out. I am looking for something like the tutorial draw code...

    - How Do I Determine The Currently Visible Area? You can probably increase your performance more by creating your bounding sphere once for each "Floor" and simply updating its position if needbe. This will not only save you time allocating memory, but also allow the GC to be less active, by giving it less data to clean up.

    - if (XNA < DirectX) { drool; } .... DirectX or XNA? I have been wanting to develop a game for a while now, and I am finally getting all my technologies together. Basically, I want to create a simple RTS that models that of starcraft because I am a major fan of that game. The problem is, I can not seem to decide if XNA will be able to do what I want it to do, or will I have to move to DX9c. I want to have multiplayer support as 1 of my big things, since the best thing about Starcraft is it's multiplayer, and I see that XNA does not have support for that sort of thing and certainly not an easy way to implement it. If you have any suggestions I would appreciate them, thanks. PS: My C++ skills are absolutely terrible, so I would probably have to learn C++ to use DX9c unless you can use it with C#.

    - MDX: Textures not appearing all the time I have some textures for labels which I have rendered onto triangles within a 3d model. They are Pool.Managed and they work fine normally, I just discovered something odd. By disabling my OnApplicationIdle loop that calls Render() (And it does nothing else) and forcing render from a toolbar button, textures will not render but the rest of the scene does Iv observed the following behaviour when I have my onapplicationidle loop disabled No z buffer / alpha blending - black boxes in place of textures forcing Render() alpha enabled - nothing z + alpha - nothing when rendered from onapplicationdle, success, nice pretty labels, etc forcing render() while onapplicationidle is active does not cause them to dissapear Any ideas on this one Tag: XNA Game Studio Express Protection level to high Game Technologies: DirectX, XNA, XACT, etc.

    - Calculating normals for large mesh with no vertex to triangle info I have tried dropping the scaling and it looks the same. I have done a test, which I assume is correct, but it is a little odd. In the pixelshader I draw the surface with the color of the normal. color is nx,ny,nz,1. This image is then saved as a 24 bit bitmap and i go in an pick a pixel which I think is too dak and see perhaps a color of 90,2,7. That corrosponds to a normal of arround 0.36 0 0.02, which has a length of 0.36 and not one. This surprises me since I explicitly in the pixelshader normalize the normal. Perhaps someone can tell me why this happens. I know that there will be rounding errors here and there and that the GPU is more relaxed than the CPU, but this is a very large error. The tool you used to show the normals, it is something I can get my hands on Did it show the little normal vectors I guess I should just get to work and render them myself, but the way I render does make it a little messy. The reson there is no red might be that this is part of the planet (did I mention this is a huge round planet ) which doesnt have terrain with normals with large x components. In other places, the red will be the dominant color, so all three are output. I just recently discovered Pix, so I dont really know if it can show the normals. It can however let me debug a specific pixel, so i should probably give that a try as well. Tag: XNA Game Studio Express Protection level to high Game Technologies: DirectX, XNA, XACT, etc.

I have made a game with 2 classes one for the game, and one for the sky box. For the skybox to function properly the class SkyBox needs to get some information from the Gam1 class. When i made a reference on the skybox class to the game1 class it said "Error 1 'Game1.modelRotation' is inaccessible due to its protection level"

case 0: //back

f = Vector3.Dot(Game1.modelRotation,new Vector3(0,0,1));

break;

I think the solution may be to make an instance of game1 somehow but being a

C# noob i am unsure on how to fix this. If anyones got any ideas that would be great

Hi,

Ensure your property modelRotation is marked as public.

can you make a vector public if so how :@

Re: XNA Game Studio Express Protection level to high

Stephen Styrchak - MSFT

You need to add a modifier to the member declarations. Here is an example that should help:

GraphicsDeviceManager graphics; // the default is private

private ContentManager content; // you can also explicitly make it private

internal Vector3 modelRotation; // internal means accessible within this assembly

public Vector3 otherThing; // public means accessible from anywhere
