Question

Say, I have a motion tween from frame 0 it has 100×100 size. Then on frame 20 the size became 100×500 so the movieclip will stretch vertically. What if I want the value be between 450 to 550 instead so when I play rapidly the animation will not looked the same? I feel like it requires action script (3.0 preferred) but I try accessing the movieclip’s variable and can’t find anything close to my requirement.

Mainly I want to randomize the size,position, skew and if possible, the glow filter’s color. (e.g. like R +- 10% from 150 and green +- 10% from 64)

Would be useful when mass-produce this MCs so the animation will not look so repetitive.

Answer 1

In your case, you may not want to “score” the animation but use ActionScript 3 to script the resizing animation. This can be accomplished by using AS3 Tween class provided by Flash.

// import the namespaces
import fl.transitions.Tween;
import fl.transitions.easing.*;

var endHeight:Number = Math.random() * 100 + 450;
var startHeight:Number = 100;
var myTween:Tween = new Tween(your_movie_clip, "height", Elastic.easeOut, startHeight, endHeight, 20);

More information on Tween class can be found on Adobe and this tutorial.
