Someone asked me an interesting question on Twitter about when one should have code on the timeline as opposed to a class. My answer was never unless you are controlling the timeline itself.
After thinking more about it, is that really the correct answer? Are there other situations where you may want to have code live on your timeline even if it doesn't have anything to do with the timeline itself?
As stupid as my question might sound, i have spent the last 2 weeks reading oop books; but could use some guidance. I have a flash project that is basically a supped up slide show. On the stage i have the following: main_mc (instance name = images_mc) = movieclip which holds "pictures" ui1 (instance name = ui1_mc) = user interface that allows user to draw on picture (when drawing is enabled) ui2 (instance name = ui2_mc) = activates invisible hit areas (buttons) on select pics, when hit area is clicked, we jump to another pic in the main_mc.
I accomplished all of this on the timeline, but am updating the code to OOP. I am having A HELL OF A TIME trying to figure out how to store references to the instances (images_mc etc..), so i can control them from varying class files. I have found it is easy to control the instances from the documentclass, but not from unrelated class files. Example: images_mc.stop(); works in document class; but ovieclip(Parent).images_mc.stop() doesn't seem to work from any class file.(ui2 class file for example);

View 3 RepliesIs there a way to make code on the timeline and code in a separate AS file communicate with each other?I have two buttons, a yes button and a no button.I have a confirm box which is a movie clip. In the movie clip I have the two buttons on it and code so that every time one of the buttons is clicked it runs a function.I have the rest of my code for the movie (so the code to make the confirm box appear) on a separate AS file.Is there a way I can define the functions on the movie clip and run the functions with the separate AS file?

How would I get to play backwards a timeline from a specific frame to another frame?
I need to be able to play back from frame 62 to 1 and from 101 to 62 depending on what frame I am on. I know I can do 2 if loops with if (currentFrame == 62) etc but what is the code to play the timeline in reverse for AS3?
I'm creating a simple banner for my site. I found some cool landing confetti code but it seems like after it hits the keyframe with the confetti actionscript it stops and the rest of my simple timeline animations don't play. I just wanted to have a few type animations and a logo fade in and out while the confetti is falling. I removed the stop on the confetti frame and after I do that the animations play but the confetti doesn't work. This code is on the main timeline that causes it to stop

I am using onLoad and onEnterFrame events to dynamically align my_mc. The problem I face is the following:When I put my code in the mc instance it works beautifully but when I put it in the timeline it does not work.[code]I assume it is something tiny, perhaps it is an issue with the correct paths of x and y. I tried in many ways changing paths to this._x and my_mc._x but unsuccessfully.

Here i'm actually not talking about a problem but rather wanted to raise a discussion thread. (Kirupa you may also move this thread to some other more relevant section. Few of my good colleagues till prefer writing code on the Flash timeline, on the frames (code as bigh as 100-150 lines), rather than using external AS files, when rest of the world has reached to AS 3.0 which is close to Java (OOP).I'm just wanted to know the big benefit of writing the code on the frames. I know that it is highly un-manageable and I have personally faced many instances of code not initializing, or behaving strange on a frame.

I have the seek bar component on my stage and need to be able to use it to seek through the timeline just like any other video player. However, I am not using this to control a FLV movie, but just need it to control where I can seek through my animation.
View 4 RepliesI have a movieclip in which I show pictures. Each picture was 1 frame long, so my button (mc) to go ahead to the next picture had the following script:
this.onRelease = function(){
_parent.nextFrame();
}
Now I've changed the timeline so that each picture is 24 frames long. By reading some posts I've found this code:
gotoAndStop(_currentframe+5);
Still I don't manage to go ahead 24 frames. Does anyone know how I can change the first code to go ahead 24 frames, or even better, to the next keyframe?
I've written a game in Flash using timeline code like this:On the main timeline:
Code:
stop();
include "includes/mySourceCode.as";
init();
Then,in mySourceCode.as I have a set of functions (including init(), of course).I know this technique of coding is frowned upon by many,but it was what I learned when I started out with Flash and it has always worked well for me. It also means I don't usually have to bother with importing classes to make most methods work as I guess they are all 'built in' to the main timeline already.
The problem I have now is that I have got the game sponsored, and the sponsor needs me to include his preloader, which is a document classfile.So I have his preloader working, and once loaded it tells the main timeline to proceed to the next frame, where I have my usual code as above - which now doesn't work.Firstly, it can't find my include files because it is now looking in the document class folder instead of the main .fla folder it usually looks in.Secondly, once I have moved my include files to the same folder as the document class, it gives me around 70 errors about undefined properties and methods, and things not being'compile time constants' whatever that means.
I am guessing that for some reason, since there is now a document class, Flash is no longer importing all the classes it usually does automatically for me - so could it be that I need to go through my whole game and figure out the class import paths for all the methods I have used? Or is there an easier way to get my code working how it was before without having to change it? If I do impoort all the right classes, should it work then or will I still face problems?

I have a Flash project which has about 90% of its code in the first frame, on a layer called 'actions'. the remeainder of the code is attached to several buttons throughout the project. I want to take the code attached to the buttons, and paste it into the first frame, 'actions' layer. what I want to know is how to do it, and still have the buttons function properly. This is in AS2, and will eventually be converted to AS3, when I get all the working code on the first frame. I don't know how to reference it, from the first frame of 'actions' layer.

I'm trying to hunt down some kind of class conflict I seem to be having when using TweeLite easing and found out the same code that errors in a document class works fine if I place it in the timeline. Example - this works in frame one of the timeline:
[Code]...
I have a parent movie that contains several buttons that load several child SWF files.The parent timeline has only 1 frame, and in that frame all the ActionScript (version 3) for the parent movie is imported with a single statement:
include "script.as";
The problem is that when a child movie loads, IF the child contains ANY ActionScript calls, it also somehow runs the code in "script.as", which accesses many elements of the parent movie which are not present in the child. This produces "NULL object reference" errors which crash the script:
TypeError: Error #1009: Cannot access a property or method of a null object reference.If I remove all ActionScript calls from the child's timeline, then the child doesn't run the parent's code - But if place so much as a stop(); call in the child timeline, then the child runs the parent's code after being loaded in.
I originally wrote this script for another project, which works fine, and then copied and pasted it to this one, so I don't understand why it's not working the same way. Earlier on I suspected the trouble might be from re-saving my current project as ActionScript 3, when before this upgrade was saved as ActionScript 2. So I went back and re-created each file in fresh AS3 FLAs, but it didn't solve the problem.The child SWFs are loaded with this code from "script.as".
var ldr:Loader = new Loader(); addChild(ldr); var url:String = "child.swf"; var urlReq:URLRequest = new URLRequest(url); ldr.load(urlReq);
Also in "script.as" is a simple trace call at the top of the file:
trace('script.as is running');
When de-bugging the file, the message 'script.as is running' appears in the output panel when each child SWF is loaded, which tells me that the child files are running the parent's code. Is there any way to prevent this from happening?

[Code]...
I had some code directly in the timeline that accessed/modified properties of some movie clips.
I then did the proper thing and moved the code to a Document class. I put the code that was formerly in the timeline into the document class constructor.
The issue I'm having is that if I access the movie clip properties "too soon" it reports that they are null. If I put the code in a timer event callback for half a second or so, or put an addFrameScript call with a frame of around 8 or higher, the movie clip references are valid and it all works.
So for some reason by the time the code in the timeline gets called all of the movie clip instances are valid. However, when inside of a document class constructor, they are not. I've tried using the ENTER_FRAME event callback but the movieclips still aren't ready.
The code is supposed to change some movie clip properties based on some loaderinfo parameters, so I do kind of need to set those properties before anything starts animating.
Is there any method with which I can get to know which of the two movieclips I'm using is lying above or below in the timeline 'layer' arrangement in flash.
what I'm asking is if have two movieclips 'a' and 'b'. One in layer 10 of timeline of flash professional and 'b' on layer 1. Will be able to change the index order using pure as3 code to visually keep the movieclip on the 10th layer on top of the movieclip on 1st layer?
