Re: [Flashcoders] Actionscript 3.0 help w/ simple HelloWorld
Hi Ron,
Thanks for the suggestion but still no luck on my end.
It seems that on my set up I need to have a constructor named the same as
the .as file and that constructor has to be initiated prior to any of the
other classes being initiated. So I set up
public class MyPackage{
public function MyPackage{
}
}
and then can either do an import or set up the .as file as my document
class and after that I can access HelloWorld or MyClass. This seems to
follow the examples that came with the Flash 9 alpha, which all use the
document class approach and none of the .as files has more than one class
in them, even though you can put more than one class inside. So I'm still
a bit flummoxed as to how the package is working for Jason and not me, ah
well. Probably something stupid I'm doing and the light will go in a few
days.
Just to complete this I've also tried creating a folder called MyPackage
and putting the .as files in there and again without the constructor named
the same as the .as file it did not work
My understanding of 'package' is that the dot path that occurs after it is
the path to the .as file so if the MyPackage.as is sitting in the same
directory as your .fla then I would only have 'package' at the top of the
file, if it were in a directory called MyPackage then the syntax would be
package MyPackage
thanks for ideas,
Rob

Re: [Flashcoders] Actionscript 3.0 help w/ simple HelloWorld
Hi Rob,
The ability to define multiple classes in a single package was removed as of
Flex 1.5. It was removed with the class modifier *private*. There is still a
way to do it though.
First you need to change your file name to match the main class that is
being defined. The main class is the class that is within the package block.
You can then define any additional classes *outside* of the package block.
Classes outside of the package block cannot have any modifiers. The classes
are scoped to the classes within the .as file; no class outside of the .as
file can access these classes.

Re: [Flashcoders] Actionscript 3.0 help w/ simple HelloWorld
Here is a good article on class/package syntax and structure:
http://probertson.com/articles/2006/07/28/one-file-many-as3-classes/
It turns out that one class per package is a Flex limitation.

Hi Jason,
I wrote a simple tutorial for AS3 (and Flex2) in FlashDevelop, doesn't
involve the FlashIDE but a good place to get started playing with AS3 and if
you're interested in flex it covers the basics of that too. Also explains my
setup for having an FD for AS2 and one for AS3.
http://danny-t.co.uk/index.php/tutorials/free-flex2-development-environment/
Hope it helps you or anyone.

RE: [Flashcoders] Actionscript 3.0 help w/ simple HelloWorld
I have a question back at you along this example.
any insights why yours can run as MyPackage.as?
Do you start out your package as:
package MyPackage
{
//class definitions
}
and then import like this:
import MyPackage.*
?
That should work.
if I change the name of the .as file to
HelloWorld.as
then all works fine
Yeah, I think it will still drill down and look for a class with the
same name if it doesn't find a package of the same name as the file. You
wouldn't want to name your files the same name as the class though...
the package file can contain multiple classes.

This seems to me as if it should work. I don't know if it is the Flash IDE
causing me grief, if there is some preference file I don't have set
correctly or what.
Other than this issue I'm having a lot of fun with AS3 especially the new
text features.

I have a question back at you along this example.
any insights why yours can run as MyPackage.as?
Do you start out your package as:
package MyPackage
{
//class definitions
}
and then import like this:
import MyPackage.*
?
That should work.

Hi Jason,
I wrote a simple tutorial for AS3 (and Flex2) in
FlashDevelop, doesn't involve the FlashIDE but a good place
to get started playing with AS3 and if you're interested in
flex it covers the basics of that too. Also explains my setup
for having an FD for AS2 and one for AS3.

Hope it helps you or anyone.

Re: [Flashcoders] Actionscript 3.0 help w/ simple HelloWorld
Hey off the top of my head, I think I see the problem.
So, you add the text field child to the HelloWorld Sprite. Adding the
child in the hello world sprite, does not add it to the stage. When you
use add child alone, you have to pretend it's this.addChild. If you
chose to import flash.display.Stage and do Stage.addChild(message_txt)
you'd see it. What you did is add the field to just the sprite. But
where's the sprite? It's nowhere still.
In the fla, I'd bet if you put
import MyPackage.*
var hw:HelloWorld = new HelloWorld();
addChild(hw);
it might just work!

Re: [Flashcoders] Actionscript 3.0 help w/ simple HelloWorld
Hi,
In your fla add:
import MyPackage.*
var hw:HelloWorld = new HelloWorld();
//You need to add the Child to the Stage
addChild(hw);
Other way to do it is set as 'Main Class 'of the fla file Helloworld.as, you
can do it in Publish settings in ActionScript option (the same where you set
the source paths).

RE: [Flashcoders] Actionscript 3.0 help w/ simple HelloWorld
Hey Jason,
If I remember correctly, I believe you also have to attach your HelloWorld
class to the stage (or was it display list?) via addChild. Instantiating it
via the constructor will only create it in memory and not automatically
attach to the display. I don't have the exact syntax, but I'm sure you can
search around on LiveDocs and get the answer you need.

I'm pretty good in AS2, but with AS3, I'm not getting a simple script
working. I have the Flash 9 AS3 preview, trying to write a simple
HelloWorld class (based on an example in the book) to show a
TextField:
//MyPackage.as
package MyPackage
{
//do I actually need this one?:
import flash.display.DisplayObjectContainer;
import flash.display.Sprite;
import flash.text.TextField;
public class HelloWorld extends Sprite
{
public function HelloWorld()
{
var message_txt:TextField = new TextField();
message_txt.text = Hello World;
addChild(message_txt); //does not show!
trace(constructor runs)//traces fine
}
}
}
Then in the .fla, I put:
import MyPackage.*
var hw:HelloWorld = new HelloWorld();
The constructor traces fine in the output window, but the TextField
does
not show. What have I done wrong? My Export settings in F9 As3
preview
are for AS 3.0 and FP9. In later scripts, I tried moving the
textfield,
changing the color, changing the stage color to be sure it wasn't
matching the textfield and this invisible, etc...(but it should show
as
black Times New Roman text by default anyway...)
Thanks,
Oh, and as a side note, I use FlashDevelop 2.0.1 and have my syntax
set
to AS3, but have notices code hinting doesn't always work or is
sometimes incomplete - has anyone else noticed that? Maybe I just
need
to update it.

Re: [Flashcoders] Actionscript 3.0 help w/ simple HelloWorld
Try adding this to your fla
addChild(hw);
In your HelloWorld class you've added your textField inside but since you
have added you HelloWorld() object to the display list of the movie it
will never get drawn.
I have a question back at you along this example. I'm running on windows
and if I set up my project that I have
my.fla
[MyPackage]
MyPackage.as (with the HelloWorld class)
using the code in the fla I never get HelloWorld to properly initiate.
Instead I get an error
**Error** Scene 1, Layer 'Layer 1', Frame 1 : Line 2, Column 8 :
[Compiler] Error #1046: Type was not found or was not a compile-time
constant: HelloWorld.
var hw:HelloWorld = new HelloWorld();
if I change the name of the .as file to
HelloWorld.as
then all works fine
any insights why yours can run as MyPackage.as?

RE: [Flashcoders] Actionscript 3.0 help w/ simple HelloWorld
That's weird that you also have to addChild() the class instance to the stage,
but makes sense I guess - I thought addChild(textField) in the class would be
enough, but I can see it now. Works. Thanks.

Hi,
In your fla add:
import MyPackage.*
var hw:HelloWorld = new HelloWorld();
//You need to add the Child to the Stage addChild(hw);
Other way to do it is set as 'Main Class 'of the fla file
Helloworld.as, you can do it in Publish settings in
ActionScript option (the same where you set the source paths).

Getting my feet wet with AS3, I just bought the AS3
cookbook and have
learned a lot already - great book. I feel like an idiot
asking this
as I'm pretty good in AS2, but with AS3, I'm not getting a simple
script working. I have the Flash 9 AS3 preview, trying to write a
simple HelloWorld class (based on an example in the book)
to show a TextField:

public function HelloWorld()
{
var message_txt:TextField = new TextField();
message_txt.text = Hello World;
addChild(message_txt); //does not show!
trace(constructor runs)//traces fine
}
}
}
Then in the .fla, I put:
import MyPackage.*
var hw:HelloWorld = new HelloWorld();
The constructor traces fine in the output window, but the TextField
