When a class does not define a constructor function explicitly, ActionScript automatically
provides a default constructor that performs no initialization on new
instances of the class. Despite this convenience, as a best practice, always include a
constructor, even if it is just an empty one. The empty constructor serves as a formal

indication that the class design does not require a constructor and should be accompanied
by a comment to that effect. For example:
class SomeClass {
// Empty constructor. This class does not require initialization.
function SomeClass ( ) {
}
}
Unlike classes, the accessibility of constructor methods cannot be controlled with
access-control modifiers. In ActionScript 3.0, all constructor methods are implicitly
considered public. (Future versions of ActionScript might, however, allow for nonpublic
constructor methods.) As a matter of style, this book always includes the
public access-control modifier when defining constructor methods, stressing the fact
that all constructor methods must be public. The following code demonstrates:
class SomeClass {
public function SomeClass ( ) {
}
}
The rule that constructor methods must be public in ActionScript 3.0
was instituted due to engineering time constraints and volatility of the
ECMAScript 4 Language Specification. For details, see Sho Kuwamoto’s
article at: http://kuwamoto.org/2006/04/05/as3-on-the-lack-ofprivate-
and-protected-constructors. (Sho is Adobe’s FlexBuilder 2’s
development team lead.)
The constructor method of an application’s main class plays a special role in a program.
It provides an opportunity to execute code immediately after the application
has started. As such, the constructor method of an application’s main class is considered
the program point of entry.
The following code adds a constructor method to our VirtualZoo class (shown in
bold):
package zoo {
public class VirtualZoo {
public function VirtualZoo ( ) {
}
}
}
Our application now has an official point of entry. When our application starts, the
Flash runtime will automatically create a VirtualZoo instance, executing the
VirtualZoo constructor method in the process. Given that our application is a virtual
zoo, the first thing we’ll do in the VirtualZoo constructor method is create a
VirtualPet object (i.e., add a pet to the zoo). We’ll learn how to create objects next.

Ab hier wird es etwas kompliziert, ob Sie das so ganz ohne Checklisten und eBook hinbekommen ist schwer zu sagen, wir drücken Ihnen aber die Daumen, nicht das dieser Kurs am Ende nicht nur kostenlos, sondern gar auch noch umsonst war. Funktionieren tut ea aber auf jeden Fall, wir selbst optimieren nur noch einmal im Monat und auch dann dauert es in der Regel keine 5 Minuten- Aber wie gesagt, wir haben es die ersten Monate auch erst einmal mit Checklisten gemacht, es ist halt nicht ganz einfach.
