RE: [Flashcoders] A Question that I've been asking for years ...
Interfaces allow 'Polymorphism'. Many say this is OOP's greatest contribution to computer science. Polymorphism occurs when a superclass stands in for a subclass. This is extremely useful when you don't know exactly what type of class (usually a concrete class) is needed at a specific spot within your code. Example: class Vehicle extends Sprite - class Car extends Vehicle class Boat extends Vehicle class Plane extends Vehicle Using the above, you can declare an attribute as type Vehicle in any spot where you don't know exactly which of the 3 vehicle types the application will be operating on. There needs to be a way (in my opinion) to define a type, it's methods/properties and whether these methods/properties are public or private. Also, you should be able to define concrete implementation within these methods. As I understand it, the closest you can get to what I've described above, is an abstract class which implements an interface, and methods within the abstract class throw an error - to make sure that a class extending the abstract overwrites said methods.

What you've described above has no need for interfaces. That's just standard OOP polymorphism based on inheritance of concrete objects. Interfaces are actually more useful for objects which aren't necessarily related via inheritance. It's worth reading back through this long (and quite old, as Jason points out) thread - there are a lot of good answers in it.

First thought was PaperVision3D, but I really wonder if it's up to doing the rotating globe with cities attached effect. Second thought was pre-rendered sequences switched frame by frame, but it looks rather more sophisticated than that - it rotates at any angle. Your second assumption is correct. It's a pre-rendered sequence. It does not rotate by any angle - it just give you the impression that it's doing that because it rotates the container (in 2d).

Re: [Flashcoders] AS3 Call a function from an array
Mike asks an important question, but assuming for the moment the function is
in the same class as playNextSection():
What you're retrieving from the XML is a String. So the line
stepArray[stepCount][fnct](val);
isn't going to call a function. It's going to try to treat a string as a
function... and the main way to do that is via [ ] notation.
I think it's most readable to separate it into two steps:
var functionName:String = stepArray[stepCount][fnct];
this[functionName](val); // assuming it's in this class. You may also have
to cast this[functionName] this as a function; can't test right now

Re: [Flashcoders] AS3 Call a function from an array
Crap...
My bad, I sent a code sample that didn't have the function calls I was
getting from the XML.
Your sample is exactly what I was looking for.
I never included the functions that the array contains because I
figured that was assumed.
They are just two functions right now that look like this...
private function playNextSection(e:MouseEvent):void{
//
var val:Number = stepArray[stepCount].pv;
var functionCall:String = stepArray[stepCount][fnct];
this[functionCall](val);
textwindow.captionTxt.text = stepArray[stepCount].txt;
stepCount++
}
private function testFunction(num:Number):void{
trace(you called testFunction, num -- +num);
}
private function testFunctionOne(num:Number):void{
trace(you called testFunctionOne, num -- +num);
}
Everything is working the way I wanted.

Re: [Flashcoders] fun with embedFonts - NOT
I would guess embedding fonts off screen in a text field will be
'slightly' more kb as you are loading a text field that is loaded but
not used AND embedding the font; whereas in the first case you are just
embedding the font in the library. But we are taking a very small
difference for sure.
