[Golist] HydroTween is enought?

You can also have a look at the go playground:

There you can find several example parsers for Go. Choose what you like best

Betreff: [Golist] HydroTween is enought?

hi,

i wonder that, can we use HydroTween comfortably instead of preparing one
for us using core GO( i mean, for example i dont want to make a tweener pack
for myself right now with GO from the beginning.)

i will enter to AS3 soon i hope. just wondering that topic now.

regards.

Burak

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

 :-)

Thanks man!  Great Idea. I'll add that in there for the next update

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!

Hey folks. I made a formal post on the latest HydroTween updates with some
usage, etc. I also updated the wiki. 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.
