Harry,

I think it has to do with complying to the ecmascript standards:

Hi. Why did they incorporate “package” keyword in AS3? Why not live without it? I find it useless.. AS2 was good enough without it, why the changing of class definition syntax?

package com.project{
public class MyClass {
}
}
class Helper1 {
}
class Helper2 {
}

it’s fine here to do.

Hey Chris,

This post is about syntax, I think you might be having some trouble with the actual concept of object-oriented design, try picking up a copy of Colin Moock’s ‘Essential ActionScript 3.0′.

Hi , i have a question: How to run a function from another class ?
I’m new in As3 (verry noob ).
Let me explain, …so :
first.as
———————————-
package {
import flash.display.*;
import flash.text.*;
public class first {
var txt1:TextField;
public function first () {
text1:txt1 = new TextField ();
text1.text = ” test text 1″;
addChild (text1);
if (text1.text = “test text 1″;) {
// hir i want to execut second function from second class
}
}
}
}

second.as
———————————————–
package {
import flash.display.*;
import flash.text.*;
public class second {
var txt2:TextField;
public function first () {
text2:txt2 = new TextField ();
text2.text = ” test text 2″;
text2.x = 100;
addChild (text2);
}
}
}

Hey kc, although constructors (in AS3) aren't allowed to actually return value, they are allowed a return-type. I always add the ":void" part just because I (personally) think it looks a bit messy if you leave it out (every other method does have a return-type, right?)..

I dont think a constructor is allowed a return type…as indicated in your first example. Thats prolly gonna cause someone a bit of confusion.

package com.rubenswieringa {
public class MyClass {
public function MyClass ():void {
}
}}

To answer your question, “oi!” will first be traced and then “Hello”.
Before the constructor of a class is executed, any expressions (variable-definitions, but also method-calls) outside of method-definitions (and within the class-definition) will be executed.
