Ease Caddy: the missing flash panel.

Ease Caddy is a really cool Flash Panel that allows you to create an easing library. I did create a file with Penner equations so you can use them both in the IDE as you use them on Tweenlite/Tweener.

Just copy and paste the following code into an empty .xml file and then import it into Ease Caddy:


How to use TweenNano for filters and frame animations

Sometimes, specially in Flash banners, we really need to bring down the file size.

One solution is to use programmatic animation, however if you are using TweenNano you might have experience 2 of its drawbacks:

  1. You can not use filters
  2. You can not use frame tweens

This is due to the fact that TweenNano does not support the TweenLite plug-ins.

However there is a very simple solution to incorporate both options without modifying the TweenNano code (you can even think of other solutions you can apply with this methodology).

Create some fake values you will apply every time the tween updates.

import com.greensock.TweenNano;
import com.greensock.easing.*;

//mc is the instance name of a movie (with 50 frames on it) on the stage
//Movieclips are dynamic classes therefore you can add any property you want
mc.frameValue = 1;
mc.blurValue = 0;
mc.strengthValue = 0;
applyGlow(); //init the movie

function applyGlow(){
        //round up since is not possible to pass floating values or zero
        //apply the values as they tween
	mc.filters = [new GlowFilter(0xFF0000, 1, mc.blurValue, mc.blurValue, mc.strengthValue)];
//call the custom function on every update
//you can combine actual properties with the fake ones on the tween
TweenNano.to(mc, 3, {x:300, delay:2, ease:Elastic.easeOut, frameValue:50, blurValue:60, strengthValue:1.5, onUpdate:applyGlow});
