Well, I'm just curious about the building blocks. I've spent hours on per-algebra, and some on algebra, and a quite a few on trigonometry learning the basics. Still, none of it had anything to do with this... What's going to make understand what you've said here. Have I skipped a math subject?
I don't think you've really skipped anything. Seems to me one of the problems is that the math books and things you've been reading aren't helping you understand how to apply the info to do what you want. It's a learning process.
I'm gonna check out the vector 2d math. This stuff is kill'n me.. I would never have guessed that formula, and don't understand the explanation. I just don't think I'm smart enough for this game stuff. I keep trying to get better at it, but I just don't have the intelligence... I guess the only thing I can do is learn math, and hope it clicks in.. not sure... just learned a bunch of algebra, some trig, and it was no use... nothing I learned in the past 4 days applied here..
Another potential problem is that you might be overwhelming yourself with trying to understand all the math at once. It took me several years in secondary school to wrap my head around these concepts. Like any practiced skill, it's only "easy" once you've done it a thousand times. Plus, if you're really trying and still don't understand it, it's not your fault. The job of any teacher or learning tool is to break down the concept. My personal experience of learning new things from the Internet is that it takes a lot more time since it isn't always broken down nicely and there's no one to really ask (except on forums). Even then, it's hard to explain it over text.
One last thing, have you checked out BSVino's Youtube videos? At the very least, they'll help you see how the math is used.
