So in this ChainedTweener class i’m gonna extend the BaseTweener class and make it execute tweenings in a cool easy chained way, so to have a glimpse of how this class can be used here’s an example :

var tweener:ChainedTweener = new ChainedTweener(_targetSprite, new Array("x","y")) ;
tweener = tweener.chainedTweenTo(new Array(100,200)).chainedTweenTo(new Array(50,300)).chainedTweenTo(new Array(1,10))

this will make a sequence of tweenings that will execute one after another, the benefits of this method is that you don’t have to worry about calculating delays to execute a sequence of tweenings anymore, and this class has the same functionalities as the BaseTweening class since this extends that.

Is there more examples of this ?

Off course, here’s a page of an example with the Document class code. In this example i’ve set the loop property of the ChainedTweener object to true, this makes the sequence of tweenings get inverted at its end. see here.

Explain more, how this exactly works and what can be done more ?

Actually what this class does is when the methods chainedTweenTo or chainedTweenFromTo are called, the tweener object creates a clone of itself, calculates the delay in function of how much tweening to go before he can fire, then pushes the clone into a static array, then the clone just pushed executes his tweening.

Also i’ve created a ChainedTweenerEvent class the contains the different events needed to listen to the chained tweenings. this class adds to the BaseTweener events a bunch of chainedTweener events that are fired when the chainedTweenTo and chainedTweenFromTo methods are used. Cool animations can happen when using the yoyo and the loop properties too.

So what can done more? well i plan to add the feature of defining sequences, store them , than call them whenever you need them, yeah , that’s definitely in my 2 do list.

Can you rapidly show me how did you extend the BaseTweener class and made this class out of it ?

yes, here’s the ChainedTweener actionscript file, see here.

Ok, i want to download this class

There you go, this archive file contains examples files + source files (ChainedTweener.as + ChianedTweenerEvent.as), download here (this has the file extension .jpeg but it’s a .rar file, i had to do that in order to host it here, please click : saveTargetAs or SaveLinkAs then when finished downloading change it’s extension to .rar, sorry for the extra work you have to do, i’ll be fixing that soon).

What is BaseTweener ?

BaseTweener is a very straightforward easy to use tweening class. It’s extensible, it supports delay, and supports a wide variety of general known tweening features.

Why should i use BaseTweener ?

the main feature of the BaseTweener class is that is extensible, i’m gonna show in my next post how can i extend my BaseTweener class to make it chainable in a very elegant, handy and easy way.

How can i use BaseTweener ?

I’ve made an example showing how to make a tweening in the very simple way :

go to Example

Finally, where the heck is the download Link ?

there you go : BaseTweener.rar , size 17Ko | archive contains : example files + source files. (this has the file extension .jpeg but it’s a .rar file, i had to do that in order to host it here, please click : saveTargetAs or SaveLinkAs then when finished downloading change it’s extension to .rar, sorry for the extra work you have to do, i’ll be fixing that soon).

how come this is not on some svn server ?

as i said the YLib library is still under heavy development, and it’s not my right to make it public yet.

Feed you inner Beatle !
