[Golist] HydroTween Updates/Post

Wed May 14 09:16:07 PDT 2008

I think the reasoning for doing that actually came down to having some difficulty with building the sequence.  I had to use the static go() call instead of instantiating a HydroTween instance when building the sequence in the parseAction() method otherwise it wouldn't work. When I used the static version it worked, but it automatically starts.

Can I make a couple more little code suggestions?
First, break out the _init routine into a private init() method. Cleaner to read, easier to repurpose, better OO practice - all of which go a long way with shared code.I know, I'm one to talk after Fuse's code ;-) but we're in AS3 land now so - best practice always!
Secondly, in adding sequencing I think your interface has gotten muddy. I get the AUTOSTART idea but don't like it, because if users wanted the extra convenience of a generate-then-start method like go() used to be, they definitely *don't* want the *in*convenience of having to set some special parameter first just to make that work.
Instead, just offer 4 ways to do the 4 different things: 1) Constructor makes a tween, leave it at that, you don't need a secondary method that does the same thing. 2) A method that auto-runs a tween, and reads like a verb, like go() 3) A noun method that generates a sequence like makeSequence(), generateSequence(), buildSequence(), makeChain(), etc. 4) A verb method that plays a sequence like sequence() or runSequence()
For example, new HydroTween() HydroTween.go():IPlayable HydroTween.parseChain():SequenceCA HydroTween.chain():SequenceCA
See what I mean? That only changes 2 things about the way you did it: it makes go() back into an auto-start method, and changes sequence() into two methods, one a "noun" and the other a "verb." More intuitive and would let you ditch AUTOSTART. (If you are bent on a 2-method interface I would just change go() to also detect and auto-start a sequence as well as a tween or tween group, and then have a makeSequence-type noun method as the second one.) 
Hey, that's just my 2 cents take it or leave it - Over all this is a very fine release my friend! Congrats

-Fantastic stuff!
Suggestion based on your color reset of -1: you might add a static const for that, like HydroTween.RESET:int = -1, which would make the code easier for people to read within the action objects.
Great job D!

Trying to get a direct download on the goplayground site, in the meantime you can get the source and example at the bottom of the blog post.

 http://blog.hydrotik.com/2008/05/13/go-048jg1-hydrotween-rev30-guide-source-code/

 Here are some snippets:

 // General/ColorMatrix Tweening!
 HydroTween.go(mc, {x:200, color:0xFF0000}, 2, 0, Elastic.easeOut, onCompleteHandler);

 // Fuse style sequencing!
 var seq1:SequenceCA = HydroTween.sequence(
     {target:fusebox, x:320, seconds:5, easing:Quadratic.easeInOut},
     {target:fusebox, Blur_blurX:8, Blur_blurY:8, seconds:5, easing:Quadratic.easeInOut},
     {target:fusebox, color:0x0000FF, seconds:5, easing:Quadratic.easeInOut},
     {target:fusebox, Blur_blurX:0, Blur_blurY:0, seconds:5, easing:Quadratic.easeInOut},
     {target:fusebox, x:400, seconds:.5, easing:Quadratic.easeInOut},
     {target:fusebox, rotation:270, seconds:.5, easing:Quadratic.easeInOut}
 );
 seq1.start();

 Also I will be at Flashbelt. Maybe we can all Go grab a bit to eat one night! :) sorry I couldn't help myself.     _______________________________________________
