Re: FLASH: An array for random movies

[Nathan Dicken]

Troy,


Here's an method that you could use.  Might at first seem a little

complicated but it works great and is reusable.  Since 10 is a two-digit

number, form a list (string) like this to hold all possible values - all

with matching numbers of digits:


Set Variable: "digits" = "2"

Set Variable: "list" = "01020304050607080910"


Next, find the length of this list (which is 20 to start out) and divide it

by the number of digits you have.  This will be the number that you use in

the random function as so:


Set Variable: "rNum" = random((length(list)/digits))+1


Esentially, your random index number "rNum" coordinates with how many

numbers you have in the list at that time.  You'd find the number for the

random MC by finding the number in the list and converting it to an integer...


Set Variable: "rValue" =

int(subString(list,((rNum*digits)-(digits-1)),digits))


For example, the length of the list to start is 20 and the number of max

digits is 2 (as in 10).  In the rNum expression, the value inside the

random function would be 10, giving you random(10)+1.  Let's say this

provides you with a rNum value of 2.  Since each value in the "list"

variable is two digits, you'd want the subString function to start on

character #3 and go two digits (or the value of digits), therefore giving

you a value of "02".  Converting this to an integer gives you your random

MC value (rValue) of 2.  The next steps would be to reform your list with

the chunk of the "list" variable that is before the "02" and the chunk

afterwards".  In this case, your new list variable would be

"010304050607080910".  Running the above rNum and rValue statements again

and reforming the list will provide you with random, but unique numbers

each time until the list variable is empty.


Let me know if you have any questions regarding this and I hope this helps.


Nathan
