If you actualy want to learn these skills then "painting by numbers" style of programming you get from most online tutorials really doenst teach you anything more than how to rip-off the tutorial.

The best bet is to learn the theory. If you know the coding lang' your going to use and learn the theory then coding somthing based on the theory is both fun and a good programming exercize it also alows you to adapt what you have learnt for use on other programs.
As for online stuff I personaly dont know anyone who studies any subject who can learn better from behind a keybord than they can sitting down in a comfy chiar with a book.

You know what you want and what you need from this material so im not trying to say your wrong. just chucking in my 2 pence worth as someone hos not long started in hobbyist games developing.

3d land involves boku calculus and any AI short of a finite state machine is going to involve modal logic. And the practice behind making an "engine" involves a pretty good level of understanding of things like inheritance and polymorphism and general abstraction of graphics protocols and...what I'm tryin to say in a nut shell is there is no cover-all step-by-step tutorial for these topics. These topics fall under advanced, and what that means is you're going to be doing less of readin tutorials and more of reading articles and books. Classes would be a huge benefit too.

The articles on this site are pretty good. I'm gonna check out that "ai depot" place myself. And I'm taking calculus over the course of this coming summer =) cause it's been years since I done that fancy stuff.

Good luck!
