Its one of those, do I say screw the pipeline and write everything myself, or do I wait and reap the benefits.
Are you under some kind of deadline? If not, wait. Isn't there other non-pipeline code you can work on?
[.net] [XNA] What have you discovered by playing with XNA?

It just occured to me that XNA Game Components require you inherit a class and that C# does not allow multiple inheritance. Kind of lame if you ask me.
I haven't had a problem with it yet. I've whipped up almost a half-dozen components so far. I've rarely come across a need for multiple inheritance with C#. There's always interfaces, which you can implement along with inheriting from a base class in C#.

While its true that you can only inherit from a single class, you *can* inherit from as many interfaces as you wish (in addition to a single class if you so choose.)
Honestly, I have never run into a case that was best solved by true multiple inheritance. The implimentation is sticky in languages like C++ and its considered to be a broken paradigm by many smart programmers (though I'm sure there are smart programmers who would disagree with them.)
I've discovered that it took me 30 minutes to get something vaguely looking like a pong clone with no prior experience with XNA. That's what I discovered and it freaking rocks.
Deriving the class you want to inherit from the game component class.

I have discovered that if you get it installed, there is no reason at all why you can't use it with .Net languages other than C#. I was kinda annoyed that I had to download both C# Express and Game Studio Express just to use the XNA Framework assemblies in a VB.Net Project. It works just fine. I plan on using it for a lot of 2D graphics, but I haven't gotten that far into it yet.

Well, I think I just learned something new. You can't pass a GraphicsDevice by reference. So, does this mean the only way to do it is by value? That seems like a lot of memory copying going on, each time I need to use it in my own home grown modules.
Isn't a GraphicsDevice a reference type? Passing by value then means that the reference is copied, not the entire object!
Quote:Original post by MoeI think what you're talking about is ownership of the GraphicsDevice object, which introduced the concept of GameServices and the GraphicsService to manage the creation and deletion of GraphicsDevices.

Is that the case? If it is, sweet! [smile] I can't say I have done much more than reading a few simple tutorials, and my own poking around with XNA. Perhaps I should do a little more digging around in the documentation...
