Each individual level has a numPlatforms variable which stores the number of platforms in that particular level. I currently have a for loop that runs from 1-numPlatforms and sets the level area (the image, more or less) the platform contains:

ActionScript 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.

Like so:

Actionscript 3 :: Targeting Unnamed Timeline Instances?
Dec 31, 2011Is there any way to control nested MovieClip instances placed on the timeline without naming them through the Properties panel? Are there any unique identifiers I can refer to?
Using instance names (like instance33, instance12, etc.) doesn't help since names are just properties, but how about references like sprite187_27 (as returned by trace(this) inside a MovieClip on the TimeLine)?

ActionScript 3.0 :: Check If Object Exists To Prevent Error #1010?
Oct 19, 2010I am trying to avoid this error:TypeError: Error #1010: A term is undefined and has no properties.It is being caused when I reference an object that does not exist. My code automically goes through an array of objects and will sometimes try to reference a location that does not exist (like [-1][6] for example).I am trying to set a variable based on another variable from an object in that array like so:ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;If it does not exist, my program stops and I am thrown that error. My question is, how can I check to see if that object's variable in the array even exists before assigning the variable?
I've tried this, but it did not work:
if(Map.baseTileArr[ob.upY][ob.leftX]){
ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;

Actionscript 3 :: Movie Plays Itself When Call Any Even Unnamed Function
Apr 23, 2010I actually don't need help, i just want to know your opinion about that weird Flash CS4 (AS3) behavior.there should be something i missed.
1) what happens: flash movie plays on any (even non-existent) function call between if(bytesLoaded==bytesTotal), and doesnot play on commented-out or blank line there
2) what should be seen instead: no action - i dont call any timeline functions so the movie shouldn't be playing.any warning or error? i dont know, flash is so *-nixy all the time in the way it handles errors.
3) where: in the.if(stage.loaderInfo.bytesLoaded==stage.loaderInfo.bytesTotal)[code]
