Random order of animation

[niklasinla]

Hi there!
I'm trying to wrap my head around making random animations out of nine mc's.
Trying to make a simple alpha animation that is random (within certain max - min duration) & also having a random order for which mc that is to be animated. Then also a stop of these animations after a set of time.
I don't really know how to do this.

Did some searching in the forums here but didn't find anything that I understand.

Anyone have some tips?

I'm in AS2.

Here is a tutorial for AS3 GSAP v11 that shows the basic approach

I don't have time (at the moment) to convert that to AS2 GSAP v12, but I would recommend the following steps:

 

1: place all of your movie clips in an array

 

myMcs = [mc1, mc2, mc3, fred_mc]

 

2: shuffle the array (search google for shuffling AS2 array)

 

3: loop through the shuffled array of movie clips and create a tween for each movie clip with a random start time like Math.random()*3 which will ensure that each tween starts within 3 seconds.

here is the as2 code:

 

import com.greensock.*;
//create array
clips = [mc1, mc2, mc3, mc4, mc5];
//shuffle it
clips = shuffleArray(clips);


function shuffleArray(arr) {
var arr2:Array = [];
while (arr.length > 0) {
arr2.push(arr.splice(Math.round(Math.random() * (arr.length - 1)), 1)[0]);
}
return arr2;
}




//construct a timeline where each item animates from opacity 0 at a random time
var timeline = new TimelineLite();
for(i=0; i< clips.length; i++){
trace(clips[i]);
timeline.from(clips[i], 0.5, {_alpha:0}, Math.random()*3); 
}
