Play random predefined set of frames

[freetL]

hi

i am pretty new to AS3 so i need a bit of help from you guys. I want to randomize the  results when i press a button, right now i have this code. i have 5 Images. Each is set on a frame where only this image is visible. So i am randomizing the frames when i click on the button. Each time it gives me a random frame number and shows me the image on that frame. Here is the code (made this with a tutorial)

stop();

random_btn.addEventListener(MouseEvent.CLICK, choose);

function choose(event:MouseEvent):void{

          var pic_number : Number = 6;

          var randomFrame:Number = Math.ceil(Math.random() * pic_number);

          trace(randomFrame);

          gotoAndStop(randomFrame);

}

Right now i want to do this more advanced, i want to animate in the image. for example i have 5 animations, the first animation goes from frame 2 till 8, the second goes from 9 to 12 and etc, so i got a set of frames (2to8)(9to12) and not like in the previos where i just got one frame. Whats the best way to accomplish it, so pressing the button gives me each time a diffrent animation, it animates from start and then stops. I hope you can help me, thx

i wanted to add also, that this should be for a small game, so the user pushs the button and gets a random pice. I would have 9 prices for example, and each price have a diffrent animation. thats the plan i am open for any kind of suggestion how to make this, thx

add the initial keyframe numbers to an array and select one of the array elements at random.  put a stop() on the last frame of each animation.

thx for your answer. I am really new to flash, so i dont understand you that much , can you paste me a short example of the code you mentiond. I am right now trying to make a intro that plays from frame 1 till frame 10, and then on frames 11 12 13 14 15 16 17 i would playe movie clips on each one( for example movie clip 1 on frame 11 as a keyframe and on the rest of the keyframes blank so it dosent appear there and i would add stop on the end of the frame in the movie so it stops and dosent repeat). Thx again for your reply,

best regards

:

stop();  // and put stops on each frame where you want the timeline to stop

var frameA:Array=[1,11,12,13,14,15,16,17];

random_btn.addEventListener(MouseEvent.CLICK, choose);

function choose(event:MouseEvent):void{

          var randomFrame:Number = frameA[Math.floor(Math.random() * frameA.length)];

          trace(randomFrame);

          gotoAndPlay(randomFrame);

}

thx , the code is good,

one last question, can i add a code that would check the last result with the current one , if the same that another result comes, basiclly what i mean that the results not repeat each another, because i get sometimes for examples, the frames 12 12 12 in a row by hiting the button. thx in advance.

use:

stop();  // and put stops on each frame where you want the timeline to stop

var frameA:Array=[1,11,12,13,14,15,16,17];

shuffle(frameA);

var index:int=0

random_btn.addEventListener(MouseEvent.CLICK, choose);

function choose(event:MouseEvent):void{

          var randomFrame:Number = frameA[index]

          trace(randomFrame);

          gotoAndPlay(randomFrame);

index=(index+1)%frameA.length;

}

function shuffle(a:Array) {

    var p:int;

    var t:*;

    var ivar:int;

    for (ivar = a.length-1; ivar>=0; ivar--) {

        p=Math.floor((ivar+1)*Math.random());

        t = a[ivar];

        a[ivar] = a

;

        a

= t;

    }

}
