Steven,
thanks for that helpfull reply. It is funny becuase I was just thinking
about the dualism, on the one hand there are these wonderfull elegant
design patterns that supposed to make things easier and on the other
hand it seems like coding has just became harder ever since when I
started applying them. Knowing about them seems sometimes almost a
burden. But the absolute elegance of how they can be used, which is
reflected in the many articles and books on them, just makes me want to
understand them better. And as you say, applying them and failing
horribly is a perfect way to get to know their individual intrisic
workings.
Strategy is the one that I am just now looking into, because the
Decorator and the possibilty of not removing them just doesnt make them
suitable for the behaviour I was after on that level.
I have something like this now.
var item = new Item()
item.executeModifier() {
modifier.execute(item.mc)
}
item.setModifier(modifier) this.modifier = modifier
item.setClip(mc) this.mc = mc
Then I will use the Decorator pattern, for decorating (what else) the
items. It so happens that some Items contain text that can be edited.
class ItemTextDecorator implements itemInterface{
_item:Iteminterface
function ItemTextDecorator(item:Iteminterface)
{
_item = item
}
function executeModifier() {
_item.executeModifier(_item.mc)
}
function setModifier(modifier) {
_item.setModifier(modifier)
}
function.setClip(mc) this.mc = mc
//additional function to set Text and edit text
}
It feels beautiful to piece things together like this :)
Just understand that you won't understand until
you code yourself into a corner a few times. :)
When will it end, if ever?
What you're experiencing is premature enlightenment. - Tyler Durden
The Gang of Four specifically warns about this, and it's important to
acknowledge that it's happening.
When people first learn about design patterns, they will immediately
begin looking for places to apply them. They will do this and fail in
some particular way, and in doing so, learn more about that design
pattern or perhaps one that they don't know of, yet. The issue most
people have is trying to solve a problem with a design pattern they just
learned without understanding that it isn't an appropriate pattern.
But, you have to do it wrong in order to learn why. Prepare to fail and
learn from those failures. It will make you a better coder.
Your initial hunch is that your problem would best be solved by the
Decorator pattern, but it very well may not be. The Decorator pattern
has fallen out of favor in recent years, as many people believe it
violates good OOP practices. It has its uses, but they're limited.
You should continue coding this using Decorator if you like, so you can
discover what its limitations are. It sounds like you're already
hitting them. It's possible that Strategy and Composition might be
useful here, as well. Just understand that you won't understand until
you code yourself into a corner a few times. :)

hi guys
i'm a bit stuck with a project i'm working on. I have a timeline
which all runs off a scrollbar similar to the one in the kirupa

amended to go horizontal and us Tweener to act a bit more smoothly)
at the moment, i have 2 sprites, 1 scrolls with the scrollbar and 1
doesn't.
on the scrolling sprite i have several panels and the start of some
ticks plus a mask for the non-scrolling textfield which is on the
other sprite
everything works as it should with this, however - i'd like to push
it a bit further so that the title (mainTitle) scrolls with the
rest of the panels but when it hits the left hand side, it
reparents to the non-scrolling sprite and stays there
you can see an example of this at http://www.bbc.co.uk/history/
british/launch_tl_british.shtml - which i think is a really elegant
solution to the problem of overlong panels, designed to take
several points of interest
i've tried having everything on the scrollable sprite and moving

[Flashcoders] AS2: Tweening a very large vector file causes shaking
Hi,
so this is a very odd problem, but I'm tweening an extremely large
vector file (about 4000x4000px), using the Fuse tween classes. Its
basically your standard slide across the surface of a massive object
from point to point effect, nothing fancy. But I'm having a bear of a
time getting it to animate smoothly. In particular, as it eases into
and out of tweens, I'm getting a weird jittering of the MC, so that it
stutters to a stop, like a car with bad brakes. The tweens themselves
are nothin fancy (see below). It seems like the problem started when I
added _rotation to the the mix. The file is vector, imported from AI.
is anyone familiar with this problem? Any recommendations for handling
this sort of basic (or so I thought) effect?
thanks,

Re: [Flashcoders] AS2: Tweening a very large vector file causes shaking
That's a myth. If he's tweening one or two things the tweening engine
makes absolutely no difference. The only differences in terms of speed
between tweening engines is how each of they handle a massive number of
property updates on a massive number of objects. So there's absolutely
no problem using Fuse on that case, the problem's somewhere else. A
bottleneck problem isn't solved with a larger bottle.
All I can say about the problem is that it seems to be related to
rendering so yeah, you'll have to look into what you're doing. Use
cacheAsBitmap WHERE appropriate (not in the whole movieclip - it's too
big for that), use scrollRect when possible.
Remember, complex vector rendering is EXPENSIVE. So 4000px x 4000px is
nearly suicidal.

RE: [Flashcoders] AS2: Tweening a very large vector file causes shaking
Fuse is really really bad IMO for tweening when performance (like with your complex vector graphic) is a concern. I dropped it because it became unusable for me in high stress situations. My current tweener-of-the-month I like is TweenLite. Also, Flash does have a hard time, tweening aside, when very very complex vector graphics are used. We designed a very complex photo-realistic assets representing the inside of an ATM machine, which took us several days to build, and had performance issues that were unrelated to any code (we tested it in fresh .flas with no code) - and these graphics were done with only Flash drawing tools. We used a ton of gradients to achieve photo-realistic rendering, but it came with a price. The main problem we had was sometimes the Flash player (8 at the time) would not load the graphic, sometimes it would - completely random. We finally got it working fine, but learned there are limits to what the browser/player/memory can render. Possible it was related to the video card too, to be fair. Anyway, something to keep in mind.

[Flashcoders] strange effects when tweening alpha
Our artist made an animated character by over-lapping different body parts. Strange thing, when I fade out the character using an alpha-tween of the outer-most clip, I can see the overlapping parts at the joints. It's like the alpha is affecting the individual parts within the movieClip rather than being applied to the composite movieClip. This is in AS2, and I just use the mx.transitions Tween class. I guess to cacheAsBitmap before doing the tween, but shouldn't alpha be applied to a composited clip by definition? I can't think of any reason why you would ever want an alpha effect to apply to the individual parts within a movie clip. I mean, if I wanted that effect I would set the alphas of the individual parts, right?

Re: [Flashcoders] strange effects when tweening alpha
I think that's what happens in Flash too (including older versions of Flash...) with timeline tweens, etc...

I mean, if I wanted that effect I would set the alphas of the individual parts, right? This is the usual behavior. It's unrelated to player version, actionscript version, or fading/tweening code used. Alphas of children containers are simply multiplied by the alpha value of the parent container. If you don't want that x-ray effect, set blendMode of the container to layer. That forces precomposition of the container content before the alpha is applied so it'll fade as a whole. That's the correct solution for that problem. Using 'empty' filters (say, a blur with a radius of 0) has the same effect. Using cacheAsBitmap *usually* has the same effect too, but it is erratic - depending on changes done to children content, it may force redrawing and you'd lose the flattened transparencies. With all those solutions, if you use different blendModes on the container children you'll lose them.

Re: [Flashcoders] strange effects when tweening alpha
Thanks Zeh. Your solution should have been SO easy for me to implement, but it seems that setting this using AS right before doing the tween doesn't work. I had to change it in the IDE. But it works great! Thanks! Zeh Fernando wrote: Our artist made an animated character by over-lapping different body parts. Strange thing, when I fade out the character using an alpha-tween of the outer-most clip, I can see the overlapping parts at the joints. It's like the alpha is affecting the individual parts within the movieClip rather than being applied to the composite movieClip. This is in AS2, and I just use the mx.transitions Tween class. I guess to cacheAsBitmap before doing the tween, but shouldn't alpha be applied to a composited clip by definition? I can't think of any reason why you would ever want an alpha effect to apply to the individual parts within a movie clip. I mean, if I wanted that effect I would set the alphas of the individual parts, right? This is the usual behavior. It's unrelated to player version, actionscript version, or fading/tweening code used. Alphas of children containers are simply multiplied by the alpha value of the parent container. If you don't want that x-ray effect, set blendMode of the container to layer. That forces precomposition of the container content before the alpha is applied so it'll fade as a whole. That's the correct solution for that problem. Using 'empty' filters (say, a blur with a radius of 0) has the same effect. Using cacheAsBitmap *usually* has the same effect too, but it is erratic - depending on changes done to children content, it may force redrawing and you'd lose the flattened transparencies. With all those solutions, if you use different blendModes on the container children you'll lose them.

Re: [Flashcoders] strange effects when tweening alpha
It's also important to clarify something Zeh mentioned when he used the phrases container children and precomposition. (Zeh said it well, but I've seen lots of folks not quite get this idea the first time they hear about it, so this is just a bit of overkill.) The Layer blend mode will not work if applied to a lone, childless movie clip on the stage. Instead, it works on a movie clip within which the children are overlapping. For example, if your character is in the root timeline, it's not possible to apply Layer to all the body parts and correct the problem. If the character is in a movie clip (as it likely is/should probably be), you apply Layer to the parent clip, not the body parts within. The default tool behavior for applying the alpha is to go into the parent and apply it to all the children. This yields the result you're seeing. Layer was introduced with Flash 8 to prevent that. It precomposes everything in the clip so the alpha is applied to one thing as a whole.

[Flashcoders] referencing external CSS file
Hi list... I have an AS2 project with 10 classes with TextFormats instanced throughout. Can anyone recommend a best practice to keep all of these TFs in one place and just have them referenced when needed? I was thinking of making a class just to return different TFs. Is there a way to load a CSS file - not glued to a specific TextField - so that all classes can reference the styles within it? Also, if I can load a global external CSS file, can I apply styles to instanced V2 components from it? - Michael M. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
[Flashcoders] Custom MovieClip Classes
List, I have a MovieClip in my Flash Library with Class Name APanel. The class obviously extends MovieClip; Also I have another MovieClip in the library Called RegistrationPanel and It's class also would extend the MovieClip's one. Now I would the like to let RegistrationPanel inherit some behaviours from APanel. But it allready extends MovieClip... How can I do this ? -- Omar M.

You need to inherit from MovieClip, but you don't have to do it directly. APanel extends MovieClip, so when RegistrationPanel extends APanel, it will also extend MovieClip. Like a dog is a mammal, and a mammal is an animal, so a dog is an animal, too.

Do you want to inherit some or all? If you want to inherit all, have RegistrationPanel extend APanel. If you want to inherit some, have RegistrationPanel instantiate APanel and have proxy methods to just the ones you want. -Steven Omar Fouad wrote: List, I have a MovieClip in my Flash Library with Class Name APanel.

Re: [Flashcoders] Custom MovieClip Classes
Nope look at this.
package amlak.ui
{
import flash.text.*;
import flash.display.MovieClip;
public class RegistrationPanel extends APanel {
public function RegistrationPanel(){
}
}
}
5000: The class 'amlak.ui.RegistrationPanel' must subclass '
flash.display.MovieClip' since it is linked to a library symbol of that
type.
I thought that RegistrationPanel would inherit also MovieClip since APanal
does. But same Error.
