ActionScript 3.0 :: How To Combine Multiple MVC Components
Jan 8, 2010
I am trying to understand how MVC works and have been able to build components using it. However, my understanding ends when I'm trying to combine these components into larger components. So for example I build a streetRacer class and it is composed of all the usual car parts and more. Inside my streetRacer class (which is considered the client in all of this, correct?) it would have parts like engine, tires, spoiler, etc. Now suppose the engine is created using MVC as are the tires and depending on the RPMs of the engine, that will change the speed at which the tires rotate. (I'm no mechanic and obviously this is highly simplified but I think it serves the example). Having said all that, how would the engine Model drive the tires to update it's view and model? Through the controller? And where would the relationship be set up? in the client?
I have a situation where I want to load portfolio of items into flash from xml. I have three categories for the portfolio and plan to create an xml file for each. I'd like to set it up so that when the user first arrives at the portfolio all of the work is displayed (and then they can narrow down the list by selecting a category).What's the best way to load all of the work in the 3 xml files? Can they be combined into one large xml object? Is it better to read through one xml file and then load the next and read through that followed by the last one?
I have finally figured out how to get both parts of my code to work. Now they don't seem to want to work together. I have a timer, so after 3 minutes of inactivity the movie will move back to frame 1. I also have a scroller that will scroll either up or down depending on the location of the mouse.
The way I have the code now allows the timer to work but the scroller just scrolls in a loop disregarding the mouse location. I'm thinking the problem is that both codes need to be properly combined so as not to conflict with each other. Can anyone lend a hand on this? I'm so close to getting this done and don't know what to do.
I'm making a simple drag-and-drop style dress up game, and I want to know if it's possible to combine multiple movie clips on different layers so that they can be gragged as a single object in the game, but retain their seperate layers. For example, if I make a hat and I want the front part of the hat to be on a layer above the doll base's head, and the back of the hat to be on a layer behind it, but the hat has to move as a whole when dragged.
Im trying to make a game where you are given the choice of 10 object, you choose 2 and they combine in the middle. Is there some actionscript i can use to make this without having to make a complex layout of frames for each button press?
i built and application that load multiple sound files play it in a sequence as the user order them but i wonder is there a way to save this sequence into one mp3 or wav file
I'm still learning flash and actionscript 3 and i am having trouble with variable and object names. I need to be able to combine variable names together (in the same way as php can combine by doing var1.var2).
My swf contains 4 loaders (image1_loader, image2_loader etc..) which are a child of (image1_content, image2_content etc.....)
I then have 4 buttons which load an image into the loader and while doing so they define the currently active loader.
Finally i have 4 control buttons - scale up/down and rotate clockwise/anticlockwise which should only control the currently active loader (as set by the buttons above)[code]...

So my buttons as well as loading the image have the event listener:
image1_btn.addEventListener(MouseEvent.CLICK, setCurrentSelection); image2_btn.addEventListener(MouseEvent.CLICK, setCurrentSelection); (and so on..) function setCurrentSelection(e:MouseEvent):void {
[Code]...
So within the rotateClockwise and rotateAntiClockwise functions i need to be able to recognise which is the currently active loader and have that number instead of the X - so if it is image1_loader - it needs to be image1_content, if 4 - image4_content... I had tried to do it as this but it doesn't like it being a string:

I was wondering what is considered to be a best practice when I have multiple components and use RemoteObject for AMF communication with a PHP backend.
Have the RemoteObject in the Main.mxml file with all the methods declared here (with handlers and all) and have all components call functions from the parentApplication, thus having a centralized result and fault handling, but making reusiability more difficult.Have a RemoteObject in each component with only the methods (and handlers) relevant to that component, thus making it easy to have clean, reusable components.
Let's say you have a large number (N) of spark buttons in your app. Let's also say that your buttons all have very similar skins (size, various effects, etc) - the only difference being the specific png that they use as their BitmapImage. Do you end up with N skin files, all differing by 1 line? Or is there a smarter way to do this while not adding a lot of code when you create the buttons in MXML (in fact, ideally, none).
I wanted to ask if there is a possibility to have both strings and radiobuttons in one column depending on the value of another column perhaps|column1 | column 2 | |r | radiobutton||s | string |If there is an r in column 1 in column2 should appear a radiobutton, otherwise column 2 just shows a string.
how do you properly handle namespace collisions in SWC files if one SWC has fewer classes from that namespace than another?I have a rather large Flash application which I'm building in Flash Builder (because coding/debugging in the Flash IDE is.not good) and I've got a ton of external SWC files which I'm linking in to my application. This has worked well so far - the file size is on the large side, but it's a lot simpler than loading in SWFs, especially since I am extending most of the classes in each SWC and adding custom code that way (it's a very design-heavy app.) The problem I'm having is when I have Flash Components, like ComboBox or TextInput, in more than one SWC. Whichever SWC was compiled last will work fine, but the others will fail with errors like the following:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@1f21adc1 to fl.controls.TextInput. at flash.display::Sprite/constructChildren() at flash.display::Sprite()

I've been researching components, ComponentShim, etc. but I'm running up against a brick wall. I thought it might be the fact that some of the components had their skins modified in the source FLA, so I tried replacing them with the default skins. How can I ensure that I have the components imported and available to all my classes, yet still be able to skin them and include them in my various FLAs?
I'm developing a Flex/AIR application that's growing big, and some of the components need to be seen from different points of view (i.e Admin, Staff, User, Guest). I've seen myself placing code in those components to handle what the user can and can't see. But it's becoming unmanageable as the code and the roles grow bigger. I was wondering what's the best way to implement multiple views inside the components while keeping them as reusable as possible.
I have created a custom component that I am using, more conveniently, as a SkinnablePopUpContainer and I want to use the same function that calls and receives data from it for several Buttons in the UI. What is the best way to achieve this without having to create a new function for each button?
I am using several instances of the same custom component on the same SWF. The component is essentially just a textfield with special sizing requirements. I also have another "wrapper" component that deals with the info from the textfield components. I was initially planning on using the stage index to associate the data with the textfield component it came from. This became more complicated than I anticipated. When I trace from the wrapper i can't get the index of the textfield components. So I got it in the component code and sent it with the info to the wrapper via a custom event. The problem there is that i can't tell which component is which because they are indexed identically. I can also see the component shim as well as the textfield.I'm just really confused about how programmatic components work on the display list.
My main Question. Is there a better way to associate the info with the proper component? I guess that's my only question. Please point me in the right direction.
EDIT2: I created a dummy place-holder component that just draws a rectangle then at runtime replaces it with programmatically generated textfield component.
Ok, this is a somewhat complicated issue dealing with SWCs and compilers. I've outlined steps to reproduce the problem below. I'm using the method outlined here to bring in Flash content to my project. I have 15-20 SWCs already, and it's working fine for those assets, the problem is specifically related to Flash's components (ComboBox, RadioButton etc.) If anyone has *any* advice on this, please let me know as we are completely stumped at this point!
The issue we're having involves using multiple external SWC files which contain AS3 components from Flash CS4. When two SWCs are linked to an ActionScript project (using Flash Builder 4 Beta (build 4.0.0)) there are collisions in the referenced classes which cause the most recently published SWC to knock out any duplicate classes in the other SWCs. A simple way to replicate this is as follows:
If I embed the same asset (i.e. image or sound file) in multiple components within a Flex Application, does the compiled swf contain the asset (and it's file size) only once or once for each time it is embedded?
I recently completed a project for a custom report UI in Flex. Now, I've been tasked with creating a new application that is essentially a "lite" version of the original UI. It will include only a few of the options that are in the original application. Also, it needs to be a separate application.
I do not want to duplicate my code, so I am planning on moving a bunch of the classes from the original application to a new library that can be shared by both applications. However, I'm trying to figure out how to make this work in my MVC environment.
For example, I have an Accordion component that lets users filter several items. Each Accordion child is an instance of a custom component with two lists (one for entities available for selection, the other for the entities the user has selected). Each child component has properties bound to the Model and functions that call Cairngorm Events.[code]...
I'm setting up an HTML page that automatically starts playing a flash video. Well at the bottom of that page - is an area with testimonials thumbnails that the user can click on loading up a small flash video in that component. Is there a way to tell the main video to pause or restart or whatever so that I don't have two videos playing at once

I am created a dynamically adding a VBox, that contains two images. Into a Custom Component that is derived from UIComponent. The problem is the Vbox that contains the two image is only a really tiny size. I would like the VBox stretch to the size of the two images. This is how I am creating the Vbox....
I created a custom textfield component that I need multiples of in a single swf. I also created a non-visual wrapper component to manage them. I am sending info from the textfields to wrapper. I was planning on using the child index to associate the info with the right component. The problem occurs when I have two instances of the textfield component and one of the wrapper on stage and I use stage.numChildren and it returns 1.
Is it bad practice/design to nest components inside components using Flex 4? Should I simply be creating components and inserting them into my main application as below, or doesn't it matter?
how i can use actionscript component code in mmxl components,as in actionscript components we use classes ,but in mmxl component we can not use classes function, so how i can use actionscript component code in mmxl component
[Code]...
but i cant use this code in mmxl components how i can use public class DialogTitle extends HBox implements IBindingClient in mmxl component code,what are the way to use it,sorry i am newbie if it is silly question
I have a problem with Flash CS5.5, AS3. I have two ScrollPane Components in my document.They are both in another scene and the (instant)names are unique. But it isnt working properly. When I go to the other scene with the second ScrollPane I get an error & it starts to flicker.
I created 2 separate swf files. One is a slideshow and the other is an interactive tool. I have have also converted these two files into a flash projector so as not to worry about plug ins that customer may or maynot have.I have another file right now which is the menu flash file that has buttons pointing it to the flash projector individual files. Since these are exe files, once the customer clicks on it, it will warn that it is potentially harmful and they have to click "run" in order for it to show.
Anyone can tell me the way to combine 2 fla files together. It mean in the 1st fla file I'll make a button and when I click the button it will run the content of 2nd fla file.
