[Flashcoders] AS3 new Class from string
Hey fellows, in AS3 how can I create class instances from a list of classes
names. Take for example something like this:
import Circle;
import Square;
import Triangle;
var list:Array = new Array(Circle,Square,Triangle);
for(var i=0;ilist.length;i++){
var class = new list[i]();
}

Re: [Flashcoders] AS3 new Class from string
Not sure since eval() is gone.
Try keeping a reference for each class in some object and use it like a hash
map.
import Circle;
import Square;
import Triangle;
var classes:Object {
Circle:Circle
, Square:Square
, Triangle:Triangle
};
var list:Array = new Array(Circle,Square,Triangle);
for(var i=0;ilist.length;i++){
var cls:Class = classes[list[i]];
var instance:* = new cls();
}
It would be nice to see a less involved solution though...

Re: [Flashcoders] AS3 new Class from string
Just remove the quotation marks from your array so it looks like this: var list:Array = new Array(Circle,Square,Triangle); Assuming your import statements are right, your code will work.

Re: [Flashcoders] AS3 new Class from string
There's also this: var ClassRef:Object = getDefinitionByName(flash.display::Sprite); var element:Sprite = new ClassRef(); That allows you to really use a string and not a class reference, which is what I think you want... But, as with Flash 8, the class reference must really exist in your swf somewhere, so you may as well do what elibol suggested...

Re: [Flashcoders] AS3 new Class from string
Actually, I would do it how Jim suggested - using the getDefinitionByName function. It's that less involved solution I did not know about. Where is this function documented?

Re: [Flashcoders] AS3 new Class from string
flash.utils.getDefinitionByName()
There's some more useful stuff in the flash.utils package.
Have a look in the docs.

Re: [Flashcoders] AS3 new Class from string
In AS3 is done like this...
import flash.utils.getDefinitionByName;
var ObClass:Class = getDefinitionByName( fully.qualified.class.name ) as
Class;
var instance = new ObClass();

Re: [Flashcoders] AS3 new Class from string
Jim:
getDefinitionByName(flash.display::Sprite);
Should read:
getDefinitionByName(flash.display.Sprite);
I think.

Re: [Flashcoders] AS3 new Class from string
I see what you mean Jim. Maybe it's best used for classes loaded via swc libraries.

RE: [Flashcoders] AS3 new Class from string
But using getDefinitionByName, can you find a class that's inside a loaded swf?
Like in this example, Test is a class inside test.swf but I get an Error #1065:
Variable Test is not defined. But it works fine if I call getDefinitionByName
from within test.swf
public function GetDefinitionByNameExample() {
var request:URLRequest = new URLRequest(test.swf);
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,completeEvent);
loader.load(request);
}
private function completeEvent(e:Event):void{
trace(completeEvent);
var ClassReference:Class = getDefinitionByName(Test) as Class;
var instance:Object = new ClassReference();
}
