Actionscript 3 :: Distributing Changes To An Existing SWF Application Theory
Jul 11, 2011
Lets say we have an online application written in AS3 and served from a server as a SWF. The first version to go out is V1.0.
Several users, some behind a proxy server, use the V1.0 application and now there is a cached copy on the client machines and the proxy server.
V1.1 is released and placed on the server. All users should see V1.1, but results will vary, some will be served the fresh copy, some will for a period receive their cache's copy, and finally some will be served the cache'd copy in the proxy server.
I can be code in the V1.0 that checks a server variable to see if it's out of date. BUT if it is out of date, is there a way in AS3 to force it download a fresh copy, or apply the differences into itself?
Considering that I don't have access to the proxy server and can't manually or automatically clear the cache.
what I am trying to do and maybe some of you nice people can point me in the right direction or present some code examples etc.I am an intermediate Flasher but have never really done anything too hardcore....Here goes.I have an html file(or maybe it's flash depending on what's easier) with 5 radio lists in a form. Each of the lists have post variables that consist of say, option1a,b,c etc... option2a,b,c etc.Once you have checked each option and submit I want to post those variables to an XML file.
NOW STEP 2....I create a flash file with 5 empty movie clips named box1,box2,box3 etc.I create individual LoadMovie actions which dynamically get the name of the .swf file they need to load in each box by calling the variables from the xml file.
I have a Flash application with one scene, three frames and a bunch of ActionScript code to provide a number of ExternalInterface hooks. The three frames contain a single Input Text box which, as the <embed> tag is resized using JavaScript, grows and shrinks (not scales) to fit. I now want to add the ability to zoom in/out of this application, for enlarging small text on screen without increasing the text point size. I thought this would be easy using the Javascript Zoom(percent) method of the Flash object, but this doesn't work because my ActionScript code contains:
[Code]...
I suspect I need to take the entire movie as I have it now, and put it inside a movie clip, add a zoom ExternalInterface call which somehow scales the movieClip, and move the External Inteterface methods I have now from the new Movie Clip outside to the stage... but this sounds like a near complete rewrite? Will this method even work? Is there a better way?
I am trying to make my flex app work on Android, and that involves making an AIR app to run on Android. Seeing as the flex app needs the mic, an AIR app is required. I am using flash builder 4.5 on win7 with air 2.6. The trouble seems to be that most of it is now not available. For example mx.containers is there, but not mx.containers.viewStack. I notice that there are obvious equivalents in spark for some components but not others. VBox, HBox, Canvas VDividedBox, AdvancedDataGrid and associated custom renderers are the components my application uses the most. What is the fastest way to make this work on Android, I am under time pressure. Is there a site somewhere that recommends the best way to do this, and what components can be replaced with which?
I have n number of movieclips, each with a different name, I need to arrange them around a centered movieclip. The movie clips are in the library, so I assume I will need to create an array and work from that?
say I load an external SWF, "objects1.swf" onto a skeleton of a car. Inside the car movieclip, there are headlights, door, and hood, each that need to be loaded with the movieclip inside of the car's respective movieclip. Instead of loading objects1_hood.swf, objects1_door.swf, and objects1_headlight.swf separately into their respective locations, I would just like to load objects1.swf, and take the 3 movie clips in it, and distribute them into their spots, eg "_root.car.headlight"
I am using a slightly modified version of [URL]. The problem I am having is that my thumbs get arranged out of order because they aren't all the same width. The way the code from the tutorial works is it reads the width of the image onLoad, then multiplies it by the number image it is.
This doesn't work, cuz some images are much thinner, so the thin images end up way too far left.
My method was to define a starting width (curWidth), then set the position of my thumb by using that value. once that is postioned, add the width of the image to curWidth plus a space. Reapeat for each image.
Code: curWidth = 10; function thumbnails_fn(k) { thumbnail_mc.createEmptyMovieClip("t" + k, thumbnail_mc.getNextHighestDepth()); tlistener = new Object();
[Code].....
The problem with this is it puts the image out of order. In fact, it orders them based on the order they download. I understand why (cuz of onLoadInit) but I am not sure what to do about it.
I'm loading several thumbs of a XML gallery in sequence, one after another, in the _x coordinates. The problem is that the thumbs do no have all the same _width, so they create some empty spaces between them if I set a distance. how can I set a distance of 5 pixels between the thumbs, no mather the width they have?
I have four objects with a .speed property. I want to compare all four and snag the object with the lowest speed. That alone I can get a grip on no problem. But, it's quite possible that 2 or more of the objects could have the same lowest speed. Here's where my ideas start to get muddled and rather involved. Compare two, toss the lowest in an array, if equal toss them both in.Compare the third to the array, if it's lower replace the existing item(s) with this one, if it's equal add it.Do a similiar thing with the fourth.To do all that I can't think of anything but a boatload of IFs and nested IFs.
I am trying to get a handle on interfaces with AS3 and am kind of at a sticking point. Someone tried to explain them to me using legos and conceptually I get the idea of consistent interaction. Where I seem to get stuck is, I don't really see how the implementation of interfaces accomplishes this.
I would like to create a swf that pulls images from a folder, creates a thumbnail for them and preloads them. This would have to work like a bare template that could pull 2 or 20 images depending on what folder it is placed in. I'm not asking for code here, what I would like to get from you is thoughts on what works, and what doesn't. paste code if you want to explain someting, but really I just want to be able to wrap my head around this, and then code it myself, and comeback here with specific questions if I run into problems. I would like to keep this to just flash and php if at all possible.
Can someone clear up for me the theory behind the fact you can not redispatch custom event?I am talking about the situation where you get custom event (in your event handler method) and try to dispatch it again as it is - and you get the Error #1034: Type Coercion failed.example:
I have been using flash since version 3 as a designer.I want to know how to make an object that I have manually placed on the stage from the library with a Class attached to it, interact with the Document Class? So I am basically dragging the item onto the stage and this item has a class attached and the Document Class with all of its SubClasses needs to know this exists.
Now I was dabbling with making geometry wars to learn AS3 Classes and it was great fun, I set up the Document Class, my enemies and Player 1 Spaceship. I worked out my different SubClasses, and everything was added to the stage by AddChild() along with all SubClasses being created through the Document Class....Every Class Object was linked to the Document Class as everything was created either by it or through SubClasses under it. So I had full control to do what I wanted. However, all I ever see are elements generated dynamically to the stage. As a designer I want to animate things here and there and then at specific times possibly gain control of this item with it's Class attached, but I want the Document to have a link to this Item.
Also can everybody please stop generating text boxes dynamically all of the time. just create a MovieClip with the form elements on it if it's a form that isnt going to change in layout at all. But this leads onto the same sort of questions, the items arent being created and added to the stage as objects so you still have to make the MovieClip Class understand the items under it exist, I would do it by the Instance Name but is this dirty these days in AS3..
My goal: To create a side-scrolling motocross game (horizontal - already have terms on side scrolling methodology).The bike - should react to jumps, etc.Wheels need to turn when gas is pressed, etc (is this a basic animation on keyboard events, or is it actually what 'drives' the machine??)The rider - should hang on to bike, lean forward, backward, etc.My question lies within where should be the best place to start? I know this isn't going to happen over night, and my primary focus is on the bike & suspension & rider physics (making sure the suspension/bike/rider react correctly to bumps).URL...
I understand flash does not allow to save text to file, but i have been using zinc 3.0 and can save and load a single text file within flash.1. run me through what the theory would be to have multiple input text fields that save to 1 text file and then is able to load the text from those text fields back into the same place? In theory or if someone knows.2. Is it possible to automatically load and save text to files using something similar to flush() with shared objects?3. Is it possible to have a username and password so multiple people can save and load there own answers? Perhaps having this password on the first frame as i have multiple frames with sl.
We have an application that works no problems on our server with FMS in test mode. As soon as we enter our FMS license key we get this error: "application is not a valid signed application loading access denied".We removed the license key and it works again, but with user limits obviously, so this is not an acceptable fix.
I am using Flash profassional cs5 and want to create an iPad application but it only allow to make iphone application. It allows to install on iPad but the resolution is very small.
I'm trying to develop a simple mxml Flex application to start Skype from the AIR/Flashplayer runtime. Is it possible to get back events from a native Windows application? In the simple example of Skype, the OS returns control to the Flex app when Skype exits. But what about native applications which have their own event model and wants to communicate with the Flex event model. For example, a Face detection system which shows "Hello" on a Flex app when the camera detects a face. Can this be done in the current Flex framework?
I am working on an Adobe AIR Application. The size on Application window is 800X600 and is contains border container and border container contains many controls. What I want is to if user re-sizes the application then that container should also be re-sized according to scale. i.e If user maximizes or minimizes the window then that border container should also be maximized or minimized respectively.
I have made one one mobile application in flash builder using flex mobile project I have a question that "why size of an .ipa file is large as I export a mobile application as iOS application.???? in compare to that same application for android takes small size!
how can i delete storage directory instances or folder while uninstalling any air application. In my application when i first time run my application, application copy some data from application directory to application storage directory. now i want to delete all data and application directory folder also while uninstalling application.
I am doing that because when i launch any update then application is accessing old data which conflict with my application new features.
I'm new to flex. Now I'm writing an flex application. I plan to split my application into some MXML files(Application as the root tag). How can I switch from one mxml to another?BTW, what is the best practice for design large flex application? Just one MXML Application and many MXML component or many MXML Application?
I have an AIR app that gets bundled with XML files that the app needs. These get put into the APP Storage Directory, of course. Works great. But when I install a new version ( which includes new XML files) , the new files don't get added or overwrite the ones from the previous version. It seems that if that directory is there from a previous install, the installer will ignore the part where it moves included files.
I want to read xml data to a mxml application from a xml file on my filesystem. The example I found was for AIR,link2, link3. But I want to target the Flash Player runtime. If I use the the tag, I can do it; however the xml compiles into my swf. How can I retain the xml file in my release build?
