Anybody know any good resources for touch interface in AS3? Maybe with example downloads of simple user interface examples such as swiping lists etc. I could write code that reacts to the mouse events but I was wondering if their is a more a intuitive way of doing it using the native touch events class? Thanks. I also believe better 3rd party classes are available but I would rather stick with the adobe classes right now unless you guys think otherwise?
Check out Multi Touch Gesture Applications and Responding to Raw Touch Data for a start.

Actually I'm developing a simple game. In my game, I need to connect multiple buttons by swiping. But I don't know which events should I use to do that. What I want is kind of similar to Candy Crush game.
Please help me out guys!
Take a look at Handling pointer input on MSDN, specifically the PointerPressed, PointerMoved, and PointerReleased events. You can keep track of the pointer information by making use of the PointerRoutedEventArgs argument passed in those events, including checking whether the pointer belongs to a mouse or if it is brought about by touching the screen. There are some good examples in each article.
I'm making an app in which I need to make some photo effects similar to Instagram's effects. I was wondering if it's possible to somehow emulate the work of Photoshop's color levels in AS3.
I've tried using AdjustColor, ColorMatrixFilter and ColorTransform classes but desired image is very hard to achieve using those.
So does anyone have a solution easier than that? or maybe someone knows a library that I couldn't find on Google?
You should have a look at Joa's image processing library.
Have a look on this library:
http://peternitsch.net/bitmapdata.js/
This is actually implemented in Javascript, but it's based on the Flash API. All You need is there. Or i can recommend Foundation ActionScript 3.0 Image Effects by Todd Yard.
Flash API reference is another good resource for inspiration.
There is another good resource for pixel manipulation found here: http://evanw.github.com/webgl-filter/. This is done in WebGL but if your target API is still Flash, then you can easily transposed the GLSL language into Pixelbender and inject the shader
into the Flash by making reference to the pbj file.
Check Grant Skinner's TweenMax plugins, especially ColorMatrixFilter.
I would like to create a 3D navigation wall similar to http://www.dior.com/couture/en_us/The-House-of-Dior/THE-HOUSE-OF-DIOR.
I've seen a similar plugin in http://www.flashloaded.com/flashcomponents/3dwall/.
However, I want to create it from scratch as I need to customize it very much.
Any starting template you know would be helpful.
A template might be helpful, but if you truly need to customize it very much, I would suggest that you learn the ins and outs of a nice 3D code library. If you do find a template, you will probably spend just as much time tweaking it only to find that it doesn't allow for what you want.
There are many existing 3D libraries for ActionScript that could make this a pretty straightforward task. PaperVision3D, Away3D or even the native Stage3D API in the Flash Player could get you going in the right direction.
If you want to customize it and have full control over the content you better learn something from scratch: Alternativa3D, Away3D, Flare3D (quite yeasy), Minko.... Those are the most popular and depends on your needs.
I have a Flash Datagrid component being populated by data from Robotlegs services. However as the datagrid needs to show more and more rows of info I need to implement a way of loading the data as it is needed. Ideally this will be as the user scrolls down the list, I have seen this in Flex examples but I could do with a pure AS3 solution. Does anyone have any guidance or ideas how to approach this?
Here is the Flex example: http://www.jamesward.com/2010/10/11/data-paging-in-flex-4/
Any guidance would be appreciated.
I think you'll need to extend the Flash DG to use something like an AsyncListView and look at the AsyncListView to see how it does it, then write it to generate the correct events when an item isn't found, but remove any dependencies to Flex. You'll also need to do something that acts like the Responder class to support having different overlapping calls to the same service.
I am looking to get into learning how to use the html5 canvas to do animations as well as other things. I have an excellent knowledge of javascript and programming in general (mostly php but can adapt to anything). However, I have not had the opportunity to do much with graphics in the past. I have created nice smooth animations using javascript/jquery but the canvas object seems to be alot more than just that. The hardest part I am finding as I have been playing with it is that you have no reference to an object on the stage unless you store the reference. For example if I create a div on the page I have that reference to the object. However, with the canvas object if you create something within it, it draws that element on the stage giving you no reference to it. So you have to manually store the details of that object as I understand it and I could be wrong (if I am please correct me).
Anyways the whole point of this post is to see if anyone can point me to some really good articles/help about working with the canvas object. Not just drawing graphics to it cause I have been able to accomplish that very easily. But I would like to articles/help on managing the objects on the canvas. I want to make sure that I am doing this correctly/efficiently for the future of the technology. Also I am willing to purchase a book on working with html5 canvas/graphics/animations but most of them that I have seen go over the whole scope of html5 and leave out alot of the details of actually working with the canvas. So if you know any good books with my requirements please recommend them here.
Any help is appreciated.
There are nice libraries to do very basic to complex graphics using HTML5/WebGL
This may not actually teach you how the animations work. But if you are interested, check Three.js
https://github.com/mrdoob/three.js/
Read article "Creating a Framework For Canvas: Objects and Mouse". Not animation, but you can find there something interestring.
Read source code of any big framework, e.h. three.js, or LibCanvas
Read "HTML5 Canvas - Native Interactivity and Animation for the Web"
