AS 2.0 - Whats your preloading strategy? Mine isint working.

Hi all,
I was wondering how people are targeting the flash 6 player with AS 2.0 in regard to a preloading class.
I tried implementing a loader class written by Ralf Bolkenburg into my own classes. I get an error message saying that my line of code that is instantiating the loader object is not permitted within my class. The below class has more features than i need, I would love to have a "barebones" version of this class

I've been swimming through many posts on preloading. Does anyone have a simple, elegant AS 2.0 preloader class they want to share? I guess my main problem is that I cant seem to set onData or onEnterFrame event from an external class(object) to a MovieClip created from that class(object) in my main movie(.fla)

I would just use the MovieClipLoader class, but I dont want to force my users to upgrade to flash player 7

Basically I have my own image class, I want to import a preloader class into it so that I can set my container MC(created by createEmptyMovieClip) width and height to the size of the jpg(or swf) once it has loaded.
I instantiate my custom image object like so:

Code:

---

var image1 : ASImage = new ASImage("test.jpg",_root.createEmptyMovieClip("image",11),10);

I saw your post a couple of days ago and made a preloader which uses a .as file. I also made a loader for swfs with high MBs exported in frame1. I will send you the script and the loader tonight if you are still interested. I guess that was what you are looking for.

That would be just beautiful.

Here is my script. Not as fancy as the one you showed but it works. You have to open each fla and make swf. I did not get any error with your file by the way.

nice work.
you da man cancer!
I would like to try eliminate the need for an external preloader movie, and just create a loader bar with the drawing API, the displays with createEmptyTextField(, and the container mc with createEmptyMovieClip(); and then position them all the preloading items dynamically.
Wouldn't it be nice to setup a preloader with one line of code and no symbols in the library or anything on the stage?

I can try, you can try, somebody else seeing this thread might try :D

I am located in Davis.

I'm making the LoaderBar class, today. I'll post it whn I'm done. Maybe we can combine our coding efforts?
~Dev

Sounds good. I started to work on it and will continue tomorrow morning. We'll see.

Ok, it's done, a simple AS2 preloader which does not require any on stage objects. Everything virtually created. Just create a text file, copy the whole script and save the file as: FlashscriptLoader.as. For the movie follow the instructions in the script.

PHP Code:
