(from v in points orderby Vector3.Distance(myPoint, v) select v).First(); But using a space partitioning datastructure is definitely the way to go, consider e.g. KD-Tree for fixed points... How about using Min?
points.Min(p=>Vector3.Distance(p, v))

I watched all the videos and recently started to actually do the coding in XNA. Everything has gone well, except for one problem in the editor. The editor works as expected as far as the UI components (buttons,checkboxes,etc.) but the tile textures do not actually draw on the grid of the layer. The white boxes dissapear as if something was drawn there, but no texture appears. Have you heard of this before? Any idea what might be wrong? For your info, I tried the unmodified solution in both VS2005 and VS2008(with the help of the conversion wizard) and get the same results in both cases. Any suggestions would be appreciated. As a side note I have used your tutorials as a basis for an isometric game engine. I will check back with you when I get it more complete if you are interested. So far it only draws the tiles and allows scrolling. Thanks again. Hi Nick,

I am fairly new to C# and XNA and had some questions that I cant seem to find in any forums, so I am pleading to you. If you could email me or contact me somehow (however you want to make contact) it would be very appreciated. First of all, I love your info and tutorials (long time listener, first time caller).

I did knotice from above that you had issues with no2 but have you had the chance to resolve them at all. all in all really helpful thanks Hi Nick, i have been looking for a tutorial to make sense of the tile engine (the ones on the xna related sites have made things really messy as they just keep hacking previous engines to bits). i have however hit a small problem, when downloading episode 2 video and 3 videoA the zip files seem to be empty although the download size is massize for an empty zip file.

If you have a bunch of components you want to be singletons, I'd make a SingletonGameComponent class which derives from GameComponent and adds in the singleton behavior. You could do the same with DrawableGameComponent to make a SingletonDrawableGameComponent if you wanted.

Let's say I wanted a Singleton GameComponent. I obviously can't inherit from both, and I'm having a hard time thinking up a design without re-creating the Singleton class for each type where I would need to inherit from multiple classes (I have a GameBase class that inherits from Game that I think would be helpful to make a Singleton, as well). Any ideas? Nick,

My implementation is a little more involved than yours ( I like the simplicity ) but does provide a threadsafe instatiation. http://blog.magenic.com/blogs/michaelc/archive/2006/03/11/Simple-but-it-works.aspx Nick,
