      • Hey all - just another noob question :-) I've got a local 2d rotation in radians that's converted to a 3d rotation matrix via: Matrix.CreateRotationZ(localRadianAngle); When I take that resultant Matrix and multiply it against the translated position matrix and apply it to my BasicEffect 's world property, my drawn object behaves and moves very oddly - I know the angle and position are correct, bu

      • Hi! I'm just in the process of writing a proper text rendering component for XNA. It fully integrates into the content pipeline and can import any TrueType font during compile time. Just like any other XNA framework content, an .xnb file is generated from the font which can at runtime be loaded by XNA's ContentManager, eg. BitmapFont myFont = this .content.load< BitmapFont >(   "Conten

      • 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

However, using a 24-bit buffer, the tga textured materials appear nice and smooth... but, the jpg
