Rand() is not Randomizing...
BlitzMax Forums/BlitzMax Beginners Area/Rand() is not Randomizing...

| There's probably a really simple solution to this that I just haven't found yet, but when I use the Rand() (or Rnd()) command, it gives me the same result. Every time. I even shut down and restarted my computer, still the same result. And its one out of about 10,000. Any help? Thanks |

| Try adding SeedRnd MilliSecs () to the start of your program. |
| ||
| KryzBlu, Have a look at the SeedRnd() command. *EDIT* And BlitzSupport takes the gold! :) |
| ||
| :D Thanks! That worked |
| ||
| it would be better to use the mersenne twist method rather then the inbuilt blitz rand(aka blitz rand sucks) |

| In what way is the blitz rand not good enough for 99.999% of users needs? |

| > In what way is the blitz rand not good enough for 99.999% of users needs? Well have a try yourself. Do: local moo = rand(0,1) In my experience 0 is often chosen about 60-75% of the time instead of it being 50/50 with 1. Dunno why. Otherdays it's totally different. But often you have to do extra stuff like this:- local moo = rand(0,9) Select moo Case 0,2,4,6,8 default end select or local arse:float = rnd(0,1.9999999999) moo = int(arse) to make things a bit more random. |

| How many samples are you taking? It will average out over an infinite timeline. Or maybe it won't. See, it's random. |
| ||
| Anybody got a BlitzMax mersenne twist function that they could post here? I left my math degree and kanji charts in my other brain. |
| ||
| er do a search for "mersenne" in these max forums, there is a module |
| ||
| Interestingly, the only way to evenly distribute Rand(0,1) over any number of samples would require it to return the opposite of the previous sample. Which isn't random at all. |
