[Xerte] FW: Transition setup?

Wed Nov 18 09:19:57 GMT 2009

That's helpful. I'll look into it - either delay the transition by a
frame, or make sure things happen in the right order. The CSS stuff is
done automatically by the Flash Player though - it's not something the
Xerte engine messes with.

Busy this morning, I'll have a look later,

Good thought.
Yep, that seems to function as expected.
I removed the default fontsize from the LO and the transition from the
icon itself.
Does that point to anything?
A transition applied directly to the icon is executing prior to the css
render?

did you try running the transition using a button after the text has
rendered? Create an ad-hoc button, add a script to
iconID.wipe(...blah...) and then click it once the text has been
rendered? Does that make any difference?

Excellent. Cheers!

Still wish I could figure out why the css is ignored by the transition
engine.
Setting the default font to the largest used in the piece lets the
transition function, but of course on smaller fonts it still thinks the
area is much larger.
The effect is that the same transition applied to smaller fonts appears
to move much slower. (As it is wiping a non-text area for a while before
it hits the visible text.)

It must be ignoring the css font def, and uses the default text size it
it's place.
Couldn't reproduce in Flash, and not a peep out of the Flash lists I
queried.

OK, got it.

Download the latest build from the website.

Create a new piece.

Add script 

trans = "wipe('in', 2, 'None', 'easeNone',2)" ; //so you can define
popular transitions upfront and reuse them throughout the piece

then in the transition field of the icon put {trans}

cheers,

Hmm. Not easy to add the variable route. Either set the icon proeprties
ahead of time, or call IconID.wipe(...) afterwards. You can call the
transitions dynamically afterwards iconID['wipe'](..blah..);

Have you tried you transition sometime after the icon has rendered? Is
it a timing issue - i.e. the tranition is being called before the screen
has updated with the textField's contents?

Cool, but I guess that means I have to pop a script icon above each icon
I want to transition:

icon.nextSibling.attributes.transition = trans_var;

At the minute it takes a string, but you can set what that string is:

icon.nextSibling.attributes.blah = "my value for the icon's property
when it gets parsed"

Well, I asked about it in a couple Flash type places and got no
response, so I went back to brute force and discovered:

If I set the default font size on the LO to the largest I'm using in the
CSS, the transition works on all fonts that size and below.
??

and

This alters the speed of the transition. (I guess it thinks it is
dealing with that larger size font).

Which leads me to the next question:

Can I use a variable in the icon "transition" parameter?
I've tried a bunch of variations and no go.
No way to even "eval" a variable into that spot?

I dunno.

This si what the engine does:

   if (transition != undefined) {
    script(this+'.'+transition, engine);
   }

so that basically runs the script iconID.wipe(...blah...), which is
here:

IconID.wipe:

ICON.prototype.wipe = function(dir, duration, easing, easeType,
startPoint) {
 var direction = dir == 'in' ? Transition.IN : Transition.OUT;
 var tween = TransitionManager.start(this, {type:Wipe,
direction:direction, duration:duration,
easing:mx.transitions['easing'][easing][easeType],
startPoint:startPoint});
 tween.mc = this;
 tween.onMotionFinished = function(){
  this.mc.broadcast('onMotionFinished');
 }
};

After that? I haven't a clue. 

I would build a very simple Flash file, recreate the situation ( a text
field in a movie clip with your styled test in, and then wipe that) and
find out if transitionManager fails even when it's not suppposed to,
before you take it any further. Take Xerte (and everything else) out of
the picture. I don't think this is a Xerte problem, as Xerte doesn't
really do much other than act to pass on the transition to the
transition manager - check the values of the parmeters getting sent?

Forget the .fla, I found it in google code.

The AS is over my head, but as far as I can make out:

The transition AS files get imported.
The guts are in
Transition.as
TransitionManager.as

They seem to use getcontent() as one of the means of determining the
area to be affected. An overlay clip is built and that is what is erased
off.

So the overlay is being built to the correct size, but the erasure
function is using some other value, not completing the "wipe" of the
overlay.

Any Flashmeisters care to tell me how far off base I am before I start
fatfingering class files?
;-)

Interesting. I'm not a big user of styles as we tend to use the default
interface.

In this situation, I would open up the XMLEngine.fla, look into how the
transition works, put some debug statements in there and see what things
look like as it runs, and see what I can figure out...

Gaa.
I found it.

Plain text works fine.
Text tagged with html tags works fine.
However, if I use a CSS style tag, the transition only covers the area
where text would have been without any formatting e.g. the default text
face/size.

Reproducible?

First crack at transitions.

Text icon, transition property added.
wipe('in', 1, 'None', 'easeNone', 2);
(the Help file example)

Transition reveals 3/4 of text block then halts.
Tried a few variations, other transitions, same result.
