The problem is not passing the arguments, but how many arguments pass.
I can't use a text file, there I could only store basic types, but not
complex properties nor objects. I think about a dirty solution:
public class ClassFactory{
public static function createInstance(className:String, args:Array):Object
switch(args.length){
case 0:
var clazz:Class = getDefinitionByName(className) as Class;
return new clazz()
break;
case 1:
var clazz:Class = getDefinitionByName(className) as Class;
return new clazz(args[0])
break;
case 2:
var clazz:Class = getDefinitionByName(className) as Class;
return new clazz(args[0],args[1])
break;
....
case N:
var clazz:Class = getDefinitionByName(className) as Class;
return new clazz(args[0],args[1],......., args[N])
break;
default 0:
throw new Error("Too many args. Max is N")
break;
}
}
}
Could you send the parameters/arguments into a text file and retrieve them
from there using loadVars?

Subject: Re: [Flashcoders] ClassFactory and Reflection in Actionscript
Oh, it's very sad. I developed a script language that can be loaded
and run at runtime in a flash movie.
At this moment I can create instances with no arguments, it's very
impressive, but if I can not pass arguments I can't continue the
project.
