Today I learned about Multi-dimensional arrays, enumerations, type convertion, and more about how arrays are stored in the memory. I'm trying to learn about classes but the XOAX tutorials are trying to teach me piano instead :saddowns: ([url]http://xoax.net/comp/cpp/console/Lesson30.php[/url]) , also I'm getting sick and tired of all the ads there. Does anybody happen to have a better simple classes tutorial than this?

Yeah, that'll take a few months. But believe it or not, this is the first time I've successfully compiled something in Code::Blocks.

I prefer Visual Studio on windows, but Code Blocks is a pretty good IDE for windows too, I just don't like the wxWidgets look.

Code Blocks doesn't actually come with a compiler, it usually just comes with the GCC compiler.
Not calling you out but it's good to note that Code Blocks can use all sorts of compilers, even the Visual Studio compiler.

I know. I choose to use Code::Blocks because it's tiny, I can make it look good and I can just slap it on my pendrive and, when I'm bored, I can just do some programming. I find Visual Studio to be too.. "clunky", if you know what I mean.

There's 12 pages of maths behind this image.

The three purple lines are axes. The lower green line is a target object on a trajectory with constant acceleration, but it could be on any polynomial trajectory. The above green line is an object that's accelerated to one possible collision course with the target.

I need a better way to draw these graphs but my first priority is to get interception courses working. The difference between an interception and a collision is that ideally interception shouldn't result in a collision, but rather after interception the objects would continue on the same trajectory.

My current plan (and the reason for most of the math) is to approximate the interception course as a collision course, and then gradually alter the course to match their velocities.

More precisely, the interception course is a function that maps a real (time) to a vector (position) - preferably without being limited to any arbitrary number of dimensions:
[img]http://latex.codecogs.com/gif.latex?%5Coverline{f}%20:%20%5Cmathbb{R}%20%5Crightarrow%20%5Cmathbb{R}^n[/img]
The target function is similar:
[img]http://latex.codecogs.com/gif.latex?%5Coverline{g}%20:%20%5Cmathbb{R}%20%5Crightarrow%20%5Cmathbb{R}^n[/img]

and there exists such a moment in time, [img]http://latex.codecogs.com/gif.latex?t_1[/img], that

[img]http://latex.codecogs.com/gif.latex?%5Coverline{f}(t_1)%20=%20%5Coverline{g}(t_1)[/img]

and

[img]http://latex.codecogs.com/gif.latex?%5Coverline{f}'(t_1)%20=%20%5Coverline{g}'(t_1)[/img]

(or at least they must get very close)

Other limitations on the solution are that its acceleration should never exceed the given maximum thrust the interceptor is capable of producing, and the solution should be a minimum of some (still unspecified) cost function - probably one that minimizes interception time and fuel, or the total amount of acceleration.

Considering how it forces a load of shit onto my C:\ drive, yes Visual studio is a clunky pile of ass.

[QUOTE=Jallen;29129633]Seriously you can buy it for $0.01 and you are still asking people to buy it for you?
Not that I'm saying it's a good thing to pay only that much for it.[/QUOTE]

Anybody who pays less than $10 is an ass. If you can't afford that, don't buy it. They really should put a minimum amount in to cover the costs and give at least a small amount to the developers and charities. It really annoys me seeing people pay such a low amount. Instead of being a greedy shit go put that cent into a charity collection box at your local Tesco or whatever.

Yeah, please don't do that. That won't even cover the paypal cost. Do you like making people lose money? Think of the children.

Basically, don't read ANY of the free OpenGL tutorials. I haven't found one that's not horrible and deprecated. (Such a thing would be much appreciated if anyone knows of one. I should probably buy a book)

I'm not an expert, but I'm sure that the Sum of the money given by the people who pay < $10, is still contributing, since if it was capped at > $10, they wouldn't have bought it anyway.

Also, they cannot incur charges from paypal, and under no circumstances can they 'lose money' just because some idiot paid $0.01

Do you understand how PayPal get their money? If you send money you have the option to incur the charge yourself or deduct it from the money the other person receives. If you're buying something like this the seller incurs the charge.

"Do you guys incur charges for payments? i.e if someone decides to be a horrible person and pay $0.01 via paypal do you actually get that money?

Lauri/Frozenbyte: heh

Lauri/Frozenbyte: no we lose money with that
&#8594;Yeah, I thought so

Lauri/Frozenbyte: the payment processor and the download/server costs make like 30-50 cents of loss to us"

Paypal does not charge you for payments under 0.31$. You simply get nothing.

[img]http://i53.tinypic.com/j63m76.png[/img]

Although I agree that anyone who buys it for under 1$ is an asshole. Because while they aren't charged for your 0.01$ payment they are still paying for your bandwidth, bringing you the great deal, etc.

So they don't charge you under $0.31 they just take it all (i.e. charge you?)

I'm sure for businesses receiving thousands of payments it's different. I doubt they'd lie about this, they don't even put it on the website. Or maybe they're only talking about bandwidth and organisational costs. Or maybe the other two transaction handlers charge you.

They don't charge you in the sense that if you are paid 0.01$ they don't charge you 0.30$ in transaction fees. Also I have a business account, the fees aren't different.

Ya, I think they are talking about bandwidth costs, etc.
