I'm using qsrand. See the function: randInt2

I found this in other forums that spoke the same problem.



"What you see is the effect of pseudo-randomness. You seed it with the time once, and it generates a sequence of numbers. Since you are pulling a series of random numbers very quickly after each other, you are re-seeding the randomizer with the same number until the next millisecond. And while a millisecond seems like a short time, consider the amount of calculations you're doing in that time."



"If you make the call fast enough the value of QTime::currentTime().msec() will not change, and you're basically re-seeding qsrand with the same seed, causing the next random number generated to be the same as the prior one."



I think I need something faster than milliseconds, maybe the CPU clock cycles.

Is there any solution to this problem?
