      • Hi, I have an app that records audio from the soundcard, saves as wave file at sampling rate of 44100/16bits. This gives a datasize of 10MB/min. For large recordings > 30 mins the file size becomes very large.

      • Hi guys, any help with this would be much appreciated, We have heard that it is not possible to export cameras or lights to an X file, as they only contain meshes. Is this true If it is, is it possible to export cameras and lights to a different format that can be used with directX, or do we have to insert all cameras and lights in C++ Thanks.

      • I've hit a really weird problem with the game I'm writing for the DBP competition. The reason it's so weird is because I'm sure it wasn't a problem before. Basically, I'm implementing the p1_wedge model in a class I have created called Player. Originally, I only had one player on screen but now I've added a second player. The problem I'm having is that it only draws the model for the second player

      • XNA uses Collections for a lot of things: ModelMeshCollection, ModelEffectCollection, EffectPassCollection, ModelMeshPartCollection, etc. which results in a lot of foreach iteration in code. I recently discovered the CLR Profiler and started poking around. It appears that using foreach on these Collections results in creation of SZArrayHelper and Enumerator helper objects. Most other systems are d

But I found that those values in FX are static; I cannot change them in code. I tried to resort to SetSamplerState(), but I don't know the sampler stage index which a sampler is bound to.
