ActionScript 3.0 :: Accessing Local Variable (Never Declared Before)
Apr 24, 2009
I work with FlashDevelop, Flex SDK and FP10 debug. I am able to access a local variable (xcorner) which is never declared before, at the condition that it must be declared after... in an "if" for instance. If I remove the declaration of xcorner, within the if, errors occur at compilation, but otherwise it works.
PHP Code:
public function pushShape2Pool(name:String, sh:Shape, rotAngle:Number = 0):int{
[...]
// xcorner is NEVER declared before !!!
coordSprites[0] = new Rectangle(xcorner, 0, globalBmp.width, globalBmp.height);
trace("xcorner=" + xcorner); // display 0
xcorner += globalBmp.width;

On the stage I have a movieclip by the name of rect_mc. Inside it have have a MovieClip square_mc.In the time line that I get when I double click on rect_mc (timeline of rect_mc) I have written the following code
var width1:Number; width1 = sqaure_mc.width;
How can I access width1 from the document class?The thing that I want to is access the variable declared (width1) in the timeline of rect_mc. Just for the sake of a example only I choose the width of MovieClip.My doubt is how can access a variable declared inside the timeline of rect_mc from the document class. It could be any variable.My document class is:
ok so lines 2 and 3 are not real code. Im an old AS2 designer guy trying to learn to code all in the first frame. So how can I see if my var is set and leave it alone if it is?
Can I call a variable declared in a SWF, and call the same variable into another SWF, when i am loading it using XML.I am declaring a variable in the "Child movie", and am loading this "Child movie" into a "Parent movie" using XML. Can I retrieve the variable declared in the "Child movie" in the "Parent movie".
Am I not targeting it properly?Alternatively, I've tried storing the flashvars URL in a variable in my root SWF and accessing it from the loaded SWF, but I can't seem to grab it. How would I grab a variable that is declared in my root SWF?
I have a problem accessing a variable which is to store a frame label. Code has been shortened to relevant parts. The following is on the main timeline.
I have a movieclip called "sections" which loads different sections of the website.When the first section is clicked thencontainerCenter is true and the evt.target.name is loaded in to the nextSection variable.Now if a 2nd section is clicked then containerCenter is false. It plays the sections movieclip. Within that movieclip it will eventually play and come to the following script:
PHP Code:
gotoAndPlay(nextSection);
For some reason it won't pick up the variable "nextSection" within the movieclip. I'm getting the error message "Access of undefined property nextSection". It has no problem when it is in the main timeline.I know you can't access a variable declared inside a function, but I have it declared outside the function as you can see above. I've just amended the variable from within the function.
what i can't figure out is how to get a reference of that asm "buffer" variable into actionscript.
(i did think of one way... what i did was to throw the "buffer" from alchemy asm, and then catch it in actionscript, but unfortunately it seems to leak a lot of memory).
is there a better alternative to doing this?
note that performance is critical, and using default alchemy marshaling is way too slow.

function drop (thumbClip, xCoord, yCoord) { thumbClip._x = xCoord; thumbClip._y = yCoord; trace (thumbClip); trace (xCoord); trace(yCoord); }
receives the variables (specified in a later function) and traces them all right, but refuses to deposit the variable thumbClip in the x and y coordinates being specified?
I replaced thumbClip with a specific movie clip, and the fucntion worked perfectly. Does this mean Flash cannot use variables to set the x and y coords to?

I was thinking about how to streamline my code the other day and looked through my classes checking for possible memory leaks. I wonder when are variables declared inside of methods clear for garbage collection? or are they not and just hang around? For instance if I have a class like this:

Since the variable was declared without reference into the class how long does it stay in Flash's memory, or does it stay indefinitely because it cannot be nullified?
I want to make such flash file, which would contact web content without asking an user to add the file in the allow list on adobe web-page, is it possible to make it without help of other programing languages?
how you would target a function's local variable through a concatenated variable string.For example:
var txt = "Hello World"; function testing(msg) { var test1 = msg;[code].........
I'd expect the trace to be "Hello World" but rather is given "undefined". So if variables created outside functions are created on the main timeline, where are local function variables created and how would you access them?
I have the following problem when loading a swf file. I have content.swf file located at [URL]. The contetn.swf access a file settings.xml located in the same dir. I load it like this:
_settingsURLRequest = new URLRequest( "settings.xml" ); _settingsLoader = new URLLoader(); _settingsLoader.load( _settingsURLRequest );
Now I have another file loader.swf located at another domain [URL]. The loader.swf file loads content.swf but content.swf search for the settings file at domain2 not domain1. I know that I can use absolute address when loading the settings file but I'm loading a lot of files and I prefer another solution. Is there a way to specify that content.swf should always search for settings.xml in its own domain no matter the fact that its being loaded from onother file in onother domain?
I have a LoadVars object called loadText in which an external variable is loaded from a text file. Now, the whole thing works, I just want to create a template to optimize the system, so here is what I need: The external variable (in an external text file) is called page1. I am assigning that external variable to a local variable (at this point the external text has already been loaded in loadText, of course):
Is there a way that i can access Local SharedObject using a swf from the net.
For example, i have a .swf that creates SharedObject running locally on my desktop computer.. But when i'm somewhere else, i need to access some of the shared objects in my desktop, is that possible?
I am having a strange issue in my flex app. I have a Video element that loads an FLV file from the same directory as the SWF app. If I move my SWF and FLV to a local directory on my computer and load the SWF in my browser, the video plays without any issues. However, if I move the same collection of files (SWF, FLV, HTML) to a network share, the video no longer loads.
[Code]...
In my netStatusHandler() callback I get an event status of: NetStream.Play.StreamNotFound.
Again, I only have this issue when loading content from a network share.
I am facing a problem in accessing Local shared object from 2 diff. swfs. Let me explain the scenario clearly.I am developing a radio widget (in maindomain.com for ex)which has a button to open a html page (placed in contentserver.com) as a popup with specific wt and ht. The html page loads the same SWF file of radio widget from "maindomain.com", means whatever changes we do for the SWF in maindomain will be reflected automatically in the popup also.Here where the problem is:
1. Say I am playing radio station "A" in main window and added this station to favourite list (which is done by storing in Share object). So when i open the popup its reflect there.
2. Now when i change radio station "A" to "B" in the popup and added "B" to favourites and closed the popup.
3. When I refresh the main window, I can get both "A" and "B" in fav, as expected.
4. But if without refreshing in main window when I changed to some new station "C" and then open the popup, it has got only radio station "A" in the fav list.
I am pretty sure this is because of Sharedobject.flush(). The thing I am wondering is, why the station "B" which is also pushed to sharedobject when added to favourite is getting deleted when I flush() the SO.?I googled many forums but not satisfied solution for this. Even I tried to get the Sharedobject.getLocal("SO","/") every time before using data in it. but no use.Is it a Flash limitation accessing LSO from diff SWF?
I am creating a web page that allows users to upload their own swf files to my web page, which are then used by the main web page as components. This creates a security issue though because I don't want the uploaded swf files to access other files on the server.
when the main webpage starts, it loads whatever third party swf files the user specifies. Is there a way for my main web page to change the security settings of the loaded swf so that the loaded swf is treated like it was loaded from another domain? Or is there another way I can provent these uploaded swfs from accessing local files on the server.
when i write prototype method and declare a variable inside the prototype method. this is fine but as sonn as i declare another variable with the same name i get an error. conflict with "variable" namespace internal. i've contact other users and they claim they don't get this same issue. i'm using flash CS3, i have flash player 10 installed but cs3 only supports up to 9 so i have 9 selected. and i'm using AS3. this is some code you can use to test to see if you get this issue:
How to access a local variable from another class? I have this powerup class that changes the speed value of the enemy in enemy class(it's a game). For instance, if player hits the powerup it changes the local variable 'speed's value inside enemy class.
I have 2 methods in a actionscript class.[code]I get duplicate variable warning. Is the local variable scope not limited to the method. Can't I declare same name variable in multiple methods?
