Re: A86: Re: question
a nice way to get random numbers that ppl can't tamper with, and that doesn't
require the OP registers is the 'r' register (which i believe is what ztetris,
or at least one of the zshell versions, if not jimmy mardell's, uses)...
something like this is good:
ld a,r
shr a
the shr a is necessary b/c the r register increases by 2 each clock cycle, so
the right bit is always the same. now a is a 7 bit random #... if you need
less bits, then shift it right some more... also, you can't really use that
method again until you do something that requires some sort of user input
because it will always be so much above the original, anyway, i'm babbling, so
i'll stop now... hope this helps.
