My plans for learning java opengl and making a video game? SCREWED.

My web app is getting crashes I need to investigate, so its off to c# asp.net land.

So, for the library I am working on, it will be able to handle sprite sheets potentially much larger than your standard curses. Meaning you could have tiles for different sorts of weapons, books, scrolls potions and all sorts of things. Think if I ever get to the stage of distribution, I should include a spritesheet that includes some weapons and shit?

does anyone have a good random number c++ code snippet?
the one I'm using right now isn't very random.

Here's a self-contained c++ implementation of the Mersenne Twister RNG.

The readme does a good job of explaining how to use it. Just put it directly in your project.

That will do Nicely, thank you

Or, you could, you know, use the Mersenne Twister algorithm that is included with C++11.

Woot! Made my first game! Sure it's console only.. and pretty terrible. But by golly it works. Now if only I could figure out how to get it out of the console.

Or just use just use a library, Plenty of them available

Doesn't rand() come with the standard libraries? I think with math.h.

[Valid_Dark]

Well right now I'm using (rand()*time ())% 6+ 1

And I don't like it.

Why multiply it by the time?  It should work just fine without that.

[Valid_Dark]

For extra randomness, duh

[GlyphGryph]

Wouldn't you be much better off using the time as a seed?

[MorleyDev]

rand() sucks though. It uses a simplistic Linear congruential generator so isn't all that random (some pretty obvious (mathematically at least) patterns show). To demonstrate what is wrong with it, have it randomly generate numbers between 0 and n with a variety of values of n, where it generates until it has generated every number between 0 and n. For a lot of values of n and depending on the seed, this will often never finish.

C++11 (the latest version of the C++ standard which is being veeerrryyyy sllooowwwlllly adopted by all the major compilers) implements a pretty clever and solid set of random number generators and since the new random generators are already in Visual Studio 2010 and GCC...why not use them? ^^

Code: [Select]

std::uniform_int_distribution<int> distribution(0, 99);
std::mt19937 engine; // Mersenne twister MT19937

int random = distribution(engine); // Generate another sample directly using the distribution and the engine objects.

Alternatively Numerical Recipes has a few decent pseudo-random number generators I'm sure the code is for somewhere (Kinda proud I own the third edition of Numerical Recipes, is that sad? xD)...

I'm not convinced it works that way.
