[vet-mm] Actionscript 3.0 Randomise

[Rob Swain]

To avoid getting a reference to frame 0 which doesn't exist, try

gotoAndPlay((Math.floor(Math.random()*24))+1);

Hi Travis,

 I am quoting from http://www.kirupa.com/forum/showthread.php?p=2112823

"  Like random(), Math.random() is used to produce random numbers,
however it functions slightly differently. Instead of providing a whole
number between 0 and up to but not including the number you pass into
random(), Math.random() instead returns a random decimal value between 0
and 1 without any need to pass it any value. If you want to have
Math.random behave like random, you need to use the following command
where n is the number you would have passed into a call to random();
   Math.floor(Math.random()*n); // = random(n) 


So , Math.floor cuts off any decimal value returned and just preserves
the whole number part. And Math.random() returns a value between 0 and
1. When multiplied by n eg. 25 and value returned is 0 to 1 times 25 = 0
to 25 ( no decimal part achieved by Math.floor ).

So replace the gotoAndPlay(random(25)); by

gotoAndPlay( Math.floor(Math.random()*25));



 Good luck

Guys,

Am currently writing the course for next year's Cert III students. As we
did Actionscript 3.0 this year, I would like to continue with it so as
to not disrupt the students' preparation. I am trying to make a flash
document with a button for interactivity that takes them to a random
frame (We covered interactive flash documents this year that jump to
pre-determined frames).

Here is the code I used to jump between frames (Used for a multi-choice
game):

start_btn.addEventListener(MouseEvent.CLICK, ask);

function ask(event:MouseEvent) :void {
gotoAndPlay("Question");
}

Here is what I have for actionscript 2.0 to jump to random frames:

on (release) {
gotoAndPlay(random ( 25 ));
}

I realise that there is no randomise function in Actionscript 3.0.

Is there anyone out there with a solution to this or should I just not
try it?!?!?

Many thanks and happy holidays

Trav
