Counting Linkages

[jspears]

Hello,
I am using Flash CS4, AS3. I have within my library pictures with linkages: pic1, pic2, ... Is there a way that I can count these?

for(var i:Number = 0; i<1000; i++){
     var linkageName:String = "pic" + i;
     if(testIfPictureExists(linkageName) == true)
           count++;
} 

Could someone please guide me in the right direction on creating the function 'testIfPictureExists()'?

Thanks in advance!!!

Give this a try.

var i:int = 0;
while(++i){
    try{
        getDefinitionByName('pic' + i);
    } catch (err:ReferenceError){
        trace('No pic' + i + ' detected. Stopping.');
        i--;
        break;
    }
}

trace(i);

private function testClassExists(className:String):Boolean {
  var toreturn:Boolean = false;
  try{
	var c:Object = getDefinitionByName(className);
	toreturn = true;
  }catch (referror:ReferenceError) {
	  trace(className +" does not exist");
  }
  return toreturn;
}

However, this will only work if the classes are actually present in the exported swf. If you only have them in the library and do not refer to them in a static context, the compiler will not include them.

Thank you very much!! That was just what I was looking for!
