A Simple Actionscript Class Definition

January 31, 2007

I know I’m a little late to the party on this one but I finally cracked Flash Classes last weekend - yay!

To be honest there wasn’t really a whole lot to crack, just the definitions of private and public functions.

Essentially a public function will execute when the class is initialised, and a private function will wait to be called, and that’s all there is to it .

Try this out:

In a text editor create a file and name it TestClass.as

Type the following:


class TestClass{

public function foo(){
trace(“Hello from Foo”);
}

private function baa(){
trace(“Hello from Baa”);
}

}

Now create a new Flash document and save it in the same folder as TestClass.as

On frame one (or any other) type:

var myTestClass = new TestClass();

now publish your movie and you should get the output “Hello from Foo”

If you now add the following line:

myTestClass.baa();

publish your movie and you should get the output “Hello from Foo”, “Hello from Baa”

Yes, it really is that easy.
