BezierTween Flake Particles

It’s been a while since I did an experiment just for the fun of it. This uses Airtight Interactive’s BezierTween class together with the Fuse tween library. Yes I know you can do bezier tweens with Fuse but I haven’t really played with that yet. Click on the image to check it out. The code for the experiment is below that.

Main Code Block
[as]import mx.transitions.Tween;
import mx.transitions.easing.*;
import com.leebrimelow.effects.*;

var leader:MovieClip = this.attachMovie(“leader”,”leader”,1);

function getNewPosition()
{
leader.x = Math.random()*Stage.width;
leader.y = Math.random()*Stage.height;
leader.p1 = Math.random()*Stage.width;
leader.p2 = Math.random()*Stage.height;
}

function tweenLeader()
{
getNewPosition();
var twX:BezierTween = new BezierTween(leader, “_x”, leader._x, leader.x, 1, true, leader.p1, leader.p2);
var twY:BezierTween = new BezierTween(leader, “_y”, leader._y, leader.y, 1, true, leader.p2, leader.p1);
twY.onMotionStopped = tweenLeader;
}

getNewPosition();
tweenLeader();

var count:Number = 2;
this.onEnterFrame = function()
{
var t:MovieClip = this.attachMovie(“flakes”,”flakes”+count,count++);
t._x = leader._x;
t._y = leader._y;
}[/as]

Flake Class

[as]import com.mosesSupposes.fuse.*;

class Flake extends MovieClip
{
public function Flake()
{
ZigoEngine.simpleSetup(Shortcuts,PennerEasing);
tweener();
}

private function tweener():Void
{
var f:Fuse = new Fuse();
f.push({target:this,scale:Math.random()*1000,tint:Math.random()*0xFFFFFF,rotation:Math.random()*520,alpha:0,seconds:Math.random()*7,func:function(){this.removeMovieClip();}});
f.start();
}

}[/as]
