That's what happens with a 50/50 chance. Change the rate to 1/7 or so and people will get the alt a lot less.

Yeah, and the randomization isn't perfect. It uses PHP's rand() function which is based on the system clock, so with a low chance such as 1 in 2 this can be affected by the server's clock or time of day.

I see...
so the reason one is comeing up more then the other is merely coincidental?

Yes.. basically. I have done one 50/50 and I got one of each on 2 adopts without having to change the DB... a member got 5 of the alts before getting the regular & another member tried for 9 days before she got the alt.

would there be a way to insert a code to make there be more than two alternates allowed? I am starting a site where I'd like to have maybe ten or so random images be possible to be picked for pets!

thanks!

ahh never mind, lol, I see on the FAQ where I ought to have looked first, there is no way right now.

Just while this topic's back on page one, I heard that mt_rand() is "truely" random, whereas rand() is not.

This is coming from someone who deals a lot with random chances on his php site, so I thought I'd put it out there. It certainly seams to be working with my finch pets!

It is closer, but still not a "true" random. The closest thing to a true random available right now is a commercial script that runs about $800.00 That basically takes wind variance calulations into effect to create the random and it is said to still only be about 95% true.

Urgh, that's sorta annoying. :P Perhaps mt_rand() could be used more in the script, even if it isn't perfect..?

Also I've heard of using seeds to make rand() more random. But which would be best and are there any better than mt_rand?

For example, I heard s_rand(time()) is what neopets use..?
