Whats the best way to generate a random number? randamize and rnd are ok if you can find an external source of variable, Ive done it with the mouse position , anyone got a snippet to do a random number call thats RANDOM!(not repeated)

Maybe try something insane, like "randomize rnd(timer()+mousex()+mousey())"

@tha_rami
its not insane but actually a good idea -
calling randomize before rnd will get you good results, and calling it like the code below will be quick,clean and very effective.

doing this will ensure that each time rnd is called that it will yeild a different number.
After calling randomize you can generate random numbers using the rnd call. example :

yes use RANDOMIZE TIMER(), doing that uses the internal clock to alter the random number generator, so it will make your program use a different random number calculation every time you run it.

I thought I was a genius when I thought that one up, but other people on here have been doing it for ages lol

hi OBese87

it was what I was looking for great, I found that unless you get an external random factor the random numbers repeated every time I started the program, I used MouseXY this was a useable method but could repeat when the button location was small, anyway all is well now with timer()

yes, if you call rnd without calling randomize first or provide the same number to randomize then the program will generate the same number every time its ran hence, the reason for using timer() to provide the random seed. You can use the mousex& y positions , but returning a variable from the timer() will ultimately prove to provide the most dynamic results.
