Feb 13, 2009Is there a way I can pass complex objects like sprites or timers through LocalConnection? It seems like you can naively pass simple objects like String, Number, Array thru the LocalConnection. But I can't seem to send other data types.I read that you have to use the method "registerClassAlias()" within the receiving SWF file before that SWF file can accept complex objects. For example, when I attempt to send instances of Sprites or Timers, I get the following error:
"Error #2044: Unhandled AsyncErrorEvent:.text=Error #2095:flash.net.LocalConnection was unable to invoke callback sendState.error=TypeError: Error #1034: Type Coercion failed: cannot convert Object@b9210b1 to flash.utils.Timer."
How can I send complex data types or are some data types not send-able?
Actionscript :: Passing Reference Types By Ref - Flex
Jun 30, 2010I know that in C# when you pass an object (non primitive) to a method the following is true: A reference to the object is passed Changes made to the object in the method are reflected outside of the method. Also, you can pass a reference to a reference in C# e.g this.changeObject(ref myObject);, in which case: Changes to the object and also to the ref are reflected outside of the method e.g. myObject = new new List(); would change the passed objects referred location. Is this possible to do in Flex/Actionscript - can a ref keyword be used?
View 1 RepliesFlash :: LocalConnection Between Swf Sending Delay & LocalConnection Sniffer Tool
May 6, 2011The first one (FLEX application) sends a message on a dedicated LocalConnection to a second one (Flash application). The Flash then answers by sending a message on another dedicated LocalConnection. This message is not directly received by the FLEX and the delay is at least 30s, up to 1 or 2 minutes! It seems the issue only occurs with Flash Player >= 10 and it never occurs with Chrome.
I didn't find anything on the web concerning a similar issue nor something in Flash Player release notes. Did someone already have this kind of problem?
By the way, is there any tool that can be used to sniffer LocalConnection communications?
Additional information:
swf are located in different frames swf are embed with swfobject I tried to delay the Flash sending, I tried to create another LocalConnection dedicated to this call but I always had same result: for all calls, the FLEX method is called after the same delay. I also put a timer in FLEX to periodically log to see if there is no background process delaying the method processing but everything seems fine
Flex :: Different Flex Swf's To Send Large Blocks Of Data Between Each Other Without Localconnection?

View 2 RepliesFlex :: Strategy For Making LocalConnection Ids Unique
Aug 8, 2009I'm using a localconnection to allow communication between an actionscript 2 swf and an actionscript 3 swf.Localconnection objects share a global namespace across a user's pc.So, this means, a user can fire up my flash app in one browser, and submit commands, back and forth, which is what i want. But the user can also fire up another browser, and all commands sent to my application will be handled by the first application if its still loaded in the first browser.When I make the LocalConnection, I specify an id, but the id must be known to the actionscript 2 swfs, and therein I find a problem. I don't know how to let the actionscript 2 swfs know what the unique id is.

View 1 RepliesActionScript 2.0 :: Passing Arguments By Reference?
May 12, 2005Is it possible to pass arguments "by reference" instead of "by value". I know it's possible in almost every programming/scripting language I came across until today, but I didn't find any hint for doing it in Actionscript For those who don't know what "by reference" means: If you want to pass a Number to a function, say
Code:
var mynumber:Number = 5;
calculate(mynumber);
and you change the value of the argument inside the function, e.g.
[code]....
then the call to calculate normally does NOT change the value of mynumber because you have passed mynumber "by value", which means the value of mynumber has been copied to the num argument. This means mynumber is 5 all the time.Now sometimes u want to be changing arguments given to a function inside the function, and this is where u will normally use references. Passing mynumber "by reference" would mean that after calling calculate the value of mynumber will be 6...I know complex Objects like MovieClips are passed by reference. But how to do it with simple DataTypes like Number, Boolean etc.?

Flex :: Does LocalConnection In Flash Player Randomly Fail Sometimes
Jul 31, 2009I have two flash movies communicating with each other using localConnection, passing an object from swfA to swfB. This seems to work fine, but will occasional fail. The only information we have is that the status event is fired with a level of error, there is no other information. Once a connection has failed it will continue to do so.
I don't know why it's happening but it is not a security problem (both movies are running on the same domain) and all communication is wrapped in a try..catch.
alternative method for communicating between movies? I've tried using ExternalInterface but it's too slow for the number of updates that are sent.

ActionScript 2.0 :: Passing Array Variables By Value Not Reference
Dec 11, 2006It took me hours to figure our why this was returning the wrong value - when assigning one array to another it passes by reference not Value. I need a way to force it to pass by values. e.g. copy the existing array and have the second array reference it, so i am free to modify the first array without changing the values of the second.[code]From the example above You see that in Actionscript when assigning one variable to another it does it my reference not value. So when you chage the value of one array it changes the value of the other automatically.I need to have the "test2" variable reference the "test1" array only by value so if modify "test1" the values of "test2" won't be modified.
View 7 RepliesFlex :: LocalConnection AsyncError : Dispatched When An Exception Is Thrown Asynchronously?
Nov 6, 2010I'm working on implementing communication between an Adobe AIR app and a browser Flash object, and the LocalConnection documentation mentions an asyncError as a potential event:
asyncError: Dispatched when an exception is thrown asynchronously — that is, from native asynchronous code.
However, that's the only documentation I can find on it. Does anyone know what this error actually means? I've searched around but couldn't find any reference -- most sample code I found does an addEventListener() for the asyncError but doesn't give any clue as to what it means or when it could occur (i.e. if it could occur when sending or when recieving).The Adobe documentation page also lists potential events for each method, but asyncError isn't listed under any specific method, only for the general class.

ActionScript 3.0 :: Passing Parenting MovieClip Reference To Button Event?
May 10, 2010I'm trying to reference a movieclip that's been passed through the class primary function (constructor/instance, tried both) but can't get a button event instance to recognize it. Since the button's based around an event, I'm not sure how to pass the reference. I stripped a lot of the code, but left the function sctructure as the button events are tied into a dynamic loop structure, a main reason why I can't move the buttons to a different class.
The example looks something like this:
package {
import flash.display.*;
import flash.text.*;
import flash.utils.*;
import flash.events.*;
[Code] .....
I'm trying to figure out how to get the site_mc reference to the button event so it can trigger other nested movieclips inside it (gallery_mc, etc). If this were AS2 it'd be a piece of cake but now I have all these invisible walls for variable passing.
ActionScript 3.0 :: Passing A Stage Reference To An Object Placed In The Design View?
Nov 28, 2010In a game me and a friend are creating, the levels are stored in MCs. In the level MCs there are several other MCs that the player should be able to interact with.
This means the objects in the levels need a stage reference. I can place all the objects manually and pass the stage ref in the constructor of the object's class, but this is a pain when the levels are going to be pretty big.
Is it possible to make sure that flash always passes a stage ref to the object even though it's not placed there by code?

LocalConnection In Mac Browsers
Feb 21, 2008I have a relatively simple localConnection between three swfs: one swf is an image gallery; another swf controls the playback of the image gallery; and the third displays xml-driven captions from the image gallery.Everything works flawlessly in a PC environment, on all browsers, using AS 2, flash player 9. But when I test in a mac environment, the captions will display on load, but it will no longer show if you refresh the page; only a cache clear and refresh will bring it back, but the same issue will happen again. The navigation doesn't work at all, ever (though the swf is loaded and visible).

ActionScript 3.0 :: LocalConnection - Communicate From One SWF To Another
Apr 23, 2009I'm having a little issue with LocalConnection - trying to communicate from one SWF to another. From my main SWF I've loaded an external SWF of same dimensions ( effectively replacing the main SWF). What I wanted was then to re-load the main SWF, but rather than have the main SWF play from the start, I wanted to go to a specific frame instead (I used a frame label called "myMarker"). Thought LocalConnection was the way to go to achieve this. Gave it a shot and it all works well locally BUT when uploaded to server it doesn't work, but throws the following error:-

ActionScript 3.0 :: LocalConnection Limitations?
Feb 12, 2009limits to number of SWFs that can establish local connection on MAC? The architecture is: One Manager ("server") and N number of other SWFs that communicate with the manager.When I embed more than 8 SWFs (manager + more than 7 dependents) and attempt to establish connection between them - only first 7 dependent swfs are capable to communicate with the manager on MAC (both Safary and FF). The rest are ignored. It doesn't seem to be an issue on PC where I went up to 20 and it worked (with some quirks of course). Is it a native behavior on MAC?
I did not check if number of connections is at stake (as opposed to number of swfs). There are 14 connections all together when 7 dependents are involved.
