There's probably a million posts about scrolling in AS3, but the problem I'm having is quite different. I have no problem making scrollbars work (have done loads of times), but I'm having a problem with custom skins. I'm basically trying to make the bar in this concept:
concept http://img842.imageshack.us/img842/5081/screenshot20130507at140.png
The key part is the thumb. When customising the skins in Flash, it scales the thumb bar (which hasn't been a problem in my previous projects, but in this one I want to have a non-scaled graphic like the one in the concept.
I've done a few searches and apparently this isn't easily achieved (something about extending the component class that I didn't really understand), but I find the UIScrollBar very easy to use. So my questions are:
Is there anyway to get UIScrollBar to do what I want?
Failing that, is there a third party equivlent of UIScrollBar that'll do what I want?
Failing those, what is the most pain-free way of making a custom scrollbar in AS3? (I realise there's a lot of tutorials for this out there, but there's too many, so if someone could point me towards a tutorial that doesn't require cause pain I'd appreciate it)
Thanks! (:

I'm a designer and animator, I newly start to coding with Adobe Animate CC, In all versions of adobe flash there is List item but i couldn't find a simple way to add image and text to it, if possible guide me how can i make a scrolling list like below sample image (scroll to receive content from server "like a news app") with simple way not complex coding. I prefer to use Adobe Animate not Adobe FlashBuilder/Flex.
Simple suggestions, Link to tutorial, ...
If you take a look here, you might find what you are looking for. However, if you are just starting to code in AS3, expect to go through some rough spots.

This scroller is pretty good, as it works with touch devices, as well as mouse input (desktop). This still requires you to create a movieclip or sprite and attach whatever items to you want to them. Read the documentation and take your time. Best of luck
I'm a beginner in programming world, never touch any programming language before. But last 3 days I decide to try make a flash game, I looked some tutorial about AS3, try it, yes I understand a little bit. But I'm still confused about this:
How do I know or to decide what codes I write first, what next? example: I want to add a hero, then a enemy, then a tiles, then a background, event listener.
Is it okay if I write code randomly, example: first I add enemy, then add tiles, add background, then add hero, etc?
What is the best way to completely learn all AS3 codes, especially about flash game dev?
I'm now in frustration mode, so I decide to learn from you all who have mastered AS3.
Check out this guide by Michael James Williams. I was in the same situation as you, and that guide helped me a lot. It goes through a lot of the basics and does a good job of explaining each step.
To answer some of your questions, the order in which you code stuff doesn't matter too much. You can always go back and adjust your old code, and you'll definitely end up doing that at some point.
For learning AS3 syntax, just look through some examples and tutorials, and don't be afraid to read the official AS3 docs. They might be intimidating at first, but once you start learning some of the terminology, they're very helpful.
you can try some video tutorials like these

If you're frustrated NOW, are you sure that you're ready to invest a couple of YEARS in becoming half-good with Actionscript? You'll have to like learning from your mistakes (an excellent way to learn, actually), because you will make thousands of them and they will cost you thousands of hours!
Do NOT write 'randomly' unless you want to greatly lengthen your time to mastery. Everything you do should have a purpose. I would start (if I were starting again) by giving myself a series of the smallest challenges: make an object appear; make it disappear; make it appear in one second from now; make it appear when I tap a key or click my mouse; make it move across the screen; make it move back; make it follow my mouse... etc.
There are many hundreds of basic programmatic elements like these that will add to your growing grasp of logic, data-structures and language. There are usually many ways to accomplish the same task -- learn and practice all of them.
Luckily, the Internet is full of good tutorials and references to Actionscript, and some decent forums like this one where you can get help.
I know this is king of old but someone might still find this useful.
I think that if you are serious about game development and also want to learn some techniques that are independent of the platform (Flash/AS3 in this case) you should use a framework.
For Flash the best game framework is the Starling along with Feather for UI.
They run on Stage3D which means that run on the GPU not the CPU which make them very fast.
With Starling you can also create mobile games that run in AIR so I think it really is something to consider.
On hsharma.com you can find a free video tutorial that goes through everything you need to know to get starting with game development so it should answer the question on how to create enemies, backgrounds, etc.
Hope this helps someone.
So I'm incredibly new to AS3, and barely know my way around.
I built a simple colouring book game, essentially changing some of the graphics of a tutorial, and replacing numbers and sizes to fit what I wanted to achieve. I then built a menu screen in a seperate scene and linked the two with code snippets and buttons to go back and forth.
The colour pickers are generated when the game is ran, however an issue I seem to be facing is that when I go back to my main menu, they are still there.
Can someone point me in the right direction as to how I can fix this? I'm sure it's a rather simple fix. I can provide the code from the tutorial if needed
I think you're right you need removechild this color to remove one color from stage... Maybe you need removechildren to remove all color, whin are on stage... Try this two way
everyone. This isn't as much of an specific technical question as it is about asking for some guidance on which steps should I follow.
The thing is I haven't worked with Flash in general for over a year and I'm very rusty, but now, here at work, I need to create an app that takes a picture, detects the face in said picture and then applies a certain animation effect. For example a slap to the face, so the detected face would shake from side-to-side or maybe something similar to the Fatify app, where it takes the pic, makes the person look fat and then you can touch it anywhere to see it animate. You get the idea.
So, my main problem is, that even after doing some extensive research, I'm still not clear on what the best method is or which would be the best tools to accomplish the animation effects on the detected face. I have read about Joa Ebert's Image Processing Library, but that seems to have been forgotten for quite a while and seeing as I have been out of the loop from the world of Flash for quite a while, I don't know if there's any novelty that could be what I'm looking for. I have also looked at countless image manipulation blog posts and tutorials, but most of it is simple stuff that doesn't really apply to what I need.
So, in summary, I would really apreciate it if anyone could point me to resources or topics that I should look into, that might prove useful for what I need to accomplish.
Thanks.
You should be using OpenCV. The library is quite extensive and has been ported to operate in many languages. OpenCV has an api for facial tracking. We've used it in our studio before for simple face tracking games.
These links are kind of dated, but should put you on the right track.

I am no expert in Flash, and I need some quick help here, without needing to learn everything from scratch.
Short story, I have to make a list where each cell contains an image, two labels, and a button.
List/Cell example:
img - label - label - button
img - label - label - button
As a Java-programmer, I have tried to quicly learn the syntax and visualness of Flash and AS3, but with no luck so far.
I have fairly understood the basics of movie clips etc.
I saw a tutorial on how to add a list, and add some text to it. So I dragged in a list, and in the code went list.addItem({label:"hello"}); , and that worked ofc. So i thought if I double-clicked the MC of the list, i would get to tweak some things. In there I have been wandering around different halls of cell-renderers etc.
I have now come to the point that I entered the CellRenderer_skinUp or something, and customized it to my liking. When this was done, I expected i could use list.addItem(); and get an empty "version" of my cell, with the img, labels and the button. But AS3 expects an input in addItem. From my object-oriented view, I am thinking that i have to create an object of the cell i have made, but i have no luck reaching it.. I tried to go
var test:CellRenderer = list.listItem;
list.addItem(test);
..But with no luck.
This is just for funsies, but I really want to make this work, however not so much that I am willing to read up on ALOT of Flash and AS3. I felt that I was closing in on the prize, but the compiler expected a semicolon after the variable (list.addItem({test:something});).
Note: If possible, I do NOT want this:
list.addItem({image:"src",label:"text",label"text",button:"text"});
Well.. It actually is what I want, but I would really like to custom-draw everything.
Does anyone get what I am trying to do, and has any answers for me? Am I approaching this the wrong way? I have searched the interwebs for custom list-cells, but with no luck.
Please, any guiding here is appreciated!

You could use a Datagrid as well, with each column pointing to the appropriate part of the data source (possibly even the same field, depending on what you're doing). You can then just use the ImageCell as the renderer for the second and third colums.
I think you're just not understanding that Adobe, in the own woolly-headed little way, is separating the Model from the View on your behalf. You hand the Model to the View and then get out of the way. The extent of what you can/should change is just telling it what renderer to pop your data into.
In fact, the fl.controls don't give you much control at all about how they work--I wouldn't go down the road of trying to create a custom itemRenderer with any signifcant functionality for them if you don't fully understand how the Display List works and if you're not comfortable digging around in the debugger and ferreting out all kinds of undocumented information.
For more details (to the extent anyone knows anything about how these work), see

Do you have the option to use the Flex Framework instead of pure Flash? It makes this kind of extension much more satisfying. It's aimed more at application developers, whereas Adobe sees Flash users more as designers.
