      • My content, using JPG's, is roughly 14.4 MB. However, the XNB version is roughly 515 MB. About 38 times bigger than the original. Is this normal What steps do I need to take to reduce the size of this I'm just begining with my development but if I can't augment this behavior of the Framework I'll have to serverly strip down my game.

      • I'm kinda new to this whole XNA C# programming stuff so sorry if this is an insanely easy question. I have recently tried to play around with some physics for a 2-d game that I am making. I tried to make an object go towards a point that the mouse clicks on. Here the code i used: private void PointPhysics( Vector2 pos, Vector2 force) { totalpos = (Position - pos); mulpos.X

It worked fine untill I tried passing data in the noise. No mater what i set in my vertices, the vertexshader aparently received uninitialized data. noise1 is always 1 and the others are always 0.

      • Can someone tell me why the following piece of code won't work on the XBox 360 I don't have an XBox 360 myself (and it will be at least 6 more months before I plan to afford one), so I can't test this at home. If anyone could tell me what's needed to make this snippet working, I'd be very happy :) // Look up the maximum texture size supported by the device Point textureResolution = new Point

      • Morning all, I've been observing some strange behaviour that appears to trace back to ID3DX10Mesh, the fact it's randomly reproducible is worrying me a bit... There is no obvious visual errors - I get the image rendered exactly as I expected it to be. I'm rendering the Stanford Bunny (note: large mesh = 32bit IB & lots of data) and for one or more initial frames the DrawSubset() call

      • Sorry to be asking such an obvious question, but I did a search and couldn't find this topic previously discussed. I'm having a problem where I seem to be getting the wrong value from the Math.Sin(x) function. The lack of search results on the subject would leave me to believe that there's not a bug in the software, so it must be something on my end. I'm trying to use sin to determine an object's

In fact, the XBox 360 works fine as a media center extender for that PC, so I know that to some extent they can communicate across the network. I cannot ping the X360 from the PC (I get timeouts) and I cannot deploy XNA program (the X360 sits at the

      • Currently volume textures aren't supported in the Content Pipeline. So if I have a mesh that references a volume texture it will fail compiling. So, is it just a matter of writing a custom importer for volume dds files or is it all the way through the pipeline Will ContentManager.Load<Texture3d>(...) work if I just write the importer Say it is so...it is Christmas after all :-)
