View 2 RepliesActionScript 2.0 :: Checking If Symbol Exists In Library
Aug 13, 2007My situation is thus: I have an XML file with entries, each of which contains a handle (linkage ID) to the movie clip that represents that entry onstage. So I dynamically load these symbols in from the library accordingly. Only problem is, I need to be able to count how many of those entries are valid, that is, how many of the XML entries have handles that actually do correctly correspond to the names of the symbols in the library. So right now in order to count the entries I am using the value of how many entries were in the XML file but this is wrong, I need a value of how many entries in the XML correspond correctly to a library symbol.
As it stands now, if all the names in the XML file match those in the .fla, all is good. Otherwise, issues. The thing is, I want this setup to be robust so the program takes responsibility and resolves issues if there are errors in the XML. Now, the only way I can see to fixing this simply, is if there is a way to check if a symbol exists in the library -- without actually trying to load it. That way I can count just those symbols from the XML file that also do exist in the library.
ActionScript 3.0 :: Checking To See If A File Exists Before Loading?
Jun 11, 2009in AS3 to check if a file exists before loading it. There was not very much about so I wrote these classes to do it. There are two classes, the FileLoaderUtils and the UtilEvent. the FileLoaderUtils has the function doesFileExist(url:String) and when called the class uses the URLStream class to attempt to load the file. If the file exists a UtilEvent.FILE_EXISTS event is dispatched. If the URL is incorrect or the file doesn not exist a UtilEvent.FILE_NOT_FOUND event is dispatched.

Actionscript 3 :: Determine If A Child Exists?
Mar 19, 2012I have an event driven flash program. I need to be able to call removeChild() if and only if an object is a child. getChildByName() and most other functions don't seem to allow for this and if you call removeChild() on an object that isn't a child it will throw an error. I suppose an option may be to catch the thrown error and just ignore it, but that seems like a bad solution.

ActionScript 3.0 :: Creating A Conditional To See If Child Exists
Mar 9, 2010I m making a basic menu effect. Normally I would animate all this in flash on the timeline but im trying to learn as much as i can about coding. I was actually impressed that i was able to create just this simple animation, but i want to write a conditional that lets me see if a child exists on the stage, if so remove it, if not run a function. Heres where I am so far.[code]as you can see the hardware text drops down and comes in from the top but stays on screen when you mouse out.basically what i want to do in my hardwareOut function is to run a conditional to see if topText exists, if so remove it and if not then gotoAndPlay().

so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler.
