partikel efek kembang api

Cara membuat partikel efek kembang api  bisa anda dapatkan script AS3 di bawah, sebelumnya anda buka dulu adobe flash milik anda, buat file baru , lanjutkan sendiri , jangan lupa tulis script di tempat Flash anda. coba baca juga : efek salju dg flash


In this free Flash ActionScript 3.0 source file and video tutorial we learn an interesting ActionScript 3.0 particle effect for making an animated fourth of july rocket blast. It uses tween effects to pull it off and also uses MOTION_FINISH event listeners on certain tweens to time things out correctly. I made this very quickly and it may have bugs... it is just an example made for people to learn advanced tween techniques and particle effect basics.

var i:uint;

var maxParts:uint;

var firstParticle:lilstar = new lilstar;

rocket1_btn.addEventListener(MouseEvent.CLICK, shootRocket1);

function shootRocket1 (event:MouseEvent):void {

rocket1_btn.visible = false;

addChild(firstParticle);

var rocket1FlyY:Tween = new Tween(firstParticle, "y", None.easeOut, 300, 120, 1, true);

var rocket1FlyX:Tween = new Tween(firstParticle, "x", None.easeOut, 200, 225, 1, true);

rocket1FlyY.addEventListener(TweenEvent.MOTION_FINISH, rocket1Explode);

function rocket1Explode(event:TweenEvent):void {

var explosionPoint:Number = firstParticle.y;

removeChild(firstParticle);

maxParts = 18;

for (i = 0; i < maxParts; i++) {

var randNum1:Number = (Math.random() * 150) - 10 + 150;

var randNum2:Number = (Math.random() * 150) - 10 + 50;

var particle:lilstar = new lilstar;

addChildAt(particle, 0);

var particleFlyX:Tween = new Tween(particle, "x", Strong.easeOut, 225, randNum1, 4, true);

var particleFlyY:Tween = new Tween(particle, "y", Strong.easeOut, explosionPoint, randNum2, 4, true);

var particleFade:Tween = new Tween(particle, "alpha", Strong.easeOut, 1, 0, 3, true);

particleFade.addEventListener(TweenEvent.MOTION_FINISH, removeParticle);

function removeParticle(event:TweenEvent):void {

removeChildAt(0);

rocket1_btn.visible = true;

}

}

}

}
