Title: SFML 2.1 Randomizer?
Post by: 5gum on November 11, 2013, 03:16:09 pm

Hello guys,
at first: Sorry for my bad English, I usally speak German but I hope you will understand me. (My question is for your luck very short ;D)

I've got 2.1 and I'm looking for something like the Randomizer in 1.6. but I can't find any similar function. Is there any random function in SFML available?

Thanks for answers

Welcome! :)

The Randomizer got removed since it didn't have anything to do with SFML anymore, plus with C++11 we now have the <random> header that provides much more in a much better way, that also means one shouldn't be using rand() and srand() anymore!

If you happen to use Thor, you can still get random numbers in one line, see here (http://www.bromeon.ch/libraries/thor/v2.0/doc/_random_8hpp.html).

C++11 random generators don't allow getting a uniform random number without setting all the engines and distributions up. For C++14, an overloaded function std::pick_a_number() has been proposed (n3551 (http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2013/n3551.pdf)).
