Re: [Flashcoders] AS3 instantiating a new class object from a string value
How about using the abstract factory design pattern?
public class MyFactory {
public static function createObject(objType:String):* {
switch (objType) {
case Foo:
return new Foo();
case Bar:
return new Bar();
default:
return new Foo();
}
}
var myObj:* = MyFactory.createObject(Foo);

RE: [Flashcoders] AS3 instantiating a new class object from a string value
MaTT, See getDefinitionByName() function in flash.utils It will give you a reference to the class name that is specified by a string. You can then use that reference to get an instance of that class. Of course you must make sure the class is loaded.

Re: [Flashcoders] AS3 instantiating a new class object from a string value
Thanks, I ended up doing this though... var ClassReference:Class = getDefinitionByName(com.foo.view.playerSkins. + aTopNavItems[i].classType) as Class; this[aTopNavItems[i].class_id] = new ClassReference(); cheers, MaTT On 7/26/07, Jake Prime [EMAIL PROTECTED] wrote: I'm not sure about the actual code to instantiate, however make sure that the class you are creating is actually compiled in the first place.

Re: [Flashcoders] AS3 instantiating a new class object from a string value
Hello :)
in AS3 to instanciate an object with only this class name (String) you can
use the flash.utils.getDefinitionByName() method :
http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/utils/package.html#getDefinitionByName()
EKA+ :)

I'm not sure about the actual code to instantiate, however make sure that the class you are creating is actually compiled in the first place. If it is not explicitly mentioned in your code somewhere it will not be compiled and will not be able to be created at run-time. jake On 26/07/07, Matt Muller [EMAIL PROTECTED] wrote: Hi, I'm trying to instantiate a new class object from a xml attribute which is a string, but its not having any of it.
