I have created an application that needs to create random numbers very quickly. I have seeded it using the time function but this seems to produce the same random number when used quickly. Anyone know of a better seed i can use or a better way of doing it. Cheers.

Are you using rand()?


the problem could be that you are seeding it every time before you use it.

wrong:while(1){srand((unsigned int) time(0));rand() //however you use it.}right:srand((unsigned int) time(0));while(1){rand() //However you use it.}

Thanks for the help, much appreciated.

Seeding the random number generator with time then calling rand() does not produce real random numbers , but alas it is useful .......... *sigh*.

There are no such things as ''real random numbers'' anyway. Not when you''re dealing with computers anyway. At least seeding should give you more or less *different* numbers every time you run the program. Fango, if you want more control over your random number function, try investigating the Monte Carlo method - you can make it as fast or as ranging as you need.
