ActionScript 2.0 :: Skip Over Branches In XML?
Jun 3, 2008
I have an tree component that is populated via XML. There are branch nodes and child nodes for each branch. This is a user interface for an elearning course. The branch nodes/folders in the tree component are for course sections and the child/leaf nodes for each are the content topics. each have a url attribute with a path to the appropriate content swf. The branch nodes/folders in the tree component do nothing when they are clicked on, as intended.
I also have previous/next buttons. They basically just navigate between leaf nodes. However, if the currently playing topic/leaf node is the first underneath a branch/folder, and I click on the 'previous' button, nothing happens. How can I set this thing to 'skip over' branch nodes? Here is the relevant code (the tree change listener, and the previous/next button event handlers:
Code:
var treeClickListener:Object = new Object();
treeClickListener.change = function() {
var item = menu_ctr.selectedItem;

I'm trying to populate a mx:tree component with values that I'm getting from BlazeDS. The returned data from BlazeDS is fine it's an ArrayCollection of Folder value objects.I've been instructed to use Cairngorm for this project. I'm pretty new to Flex and Cairngorm. According to the limited documentation that I've read online I should populate the model with data so I've stuck the array collection there.What I'm stuck with is trying to update the tree component. I feel that I need some way to notify the container component for the tree that the data (i.e. the subfolders) is available on the model. I was hoping that it would be possible to fire a function in the container component to add the subfolders as children of the selected node (I could chuck this on the model before the remote object call I guess) then fire tree.invalidateList() and tree.validateNow(). Any ideas?

I have (4) buttons with a play action that all play the same series of frames labeled:"1out"(19 frames long), when they get to the (19th) frame the action at that frame tells it to goto frame label "begin". I want only one of those buttions to have a different action when it gets to frame 19, instead of going to frame label"begin" I want it to goto frame label "2in" I thought I set up the code right for the single button, and frame 19 but it wont work,

Is there a way to skip to the next record in a for loop, without executing whats in the for loop? I hade an idea:
Code:
for (var i=0;i<testXml.product.length();i++) {
if (testXml.product[i].related != productToRelate) {
next();
};
Execute some code
};
The "else" isn't really working in the real code, so I really need a way to skip the record in some case.

I am looking for an actionscript that will go to a certain frame in the timeline, play several frames and then jump to another frame in the timeline. Basically, I want to use this on several different buttons that use the same animation sequence to get to another part of the timeline.
The following is a scenario, but not script:
Buttons A and B are on Frame 1. Animation is on Frames 2-20:
When Button A is pressed, go to Frame 2. Play Frames 2-20, then go to Frame 21.
When Button B is pressed, go to Frame 2. Play Frames 2-20, then go to Frame 22.
I am currently doing this in a different way.
Buttons A and B are on Frame 1. Animations for Buttons A and B are the same, but are located on different frames. Animations for Button A would be on Frames 2-20. Animations for Button B would be on Frames 21-39. So...
When Button A is pressed, go to Frame 2. Play Frames 2-20 and stop on Frame 20.
When Button B is pressed, go to Frame 21. Play frames 21-39 and stop on Frame 39.
Do I have to create this extra timeline? Can I just put the animation in a separate movie? How can I play the movie and then connect each button to different parts of the timeline after the movie ends?

I'm making a flash project and I have 10 different videos on it (embedded using FlVPlayback) and all the videos have the same stupid intro. My boss would like me to add a "skip intro" button which would allow you to jump to about 19 seconds in the video.
what I have done so far is insterted a video file without the introduction in a new keyframe and have the "skip intro" button linked to keyframe.the only problem is that if you do not wish to press the skip intro button, it stays up on the screen the entire time, and we would like it to disappear. I've thought about using skipintro.alpha = 0 at a cuePoint located 19 seconds in, but i'm not really sure how that would work.

I am editing a .FLA file that has been given to me. I would like to have the movie jump frames (skip frames) to cut out a part of the movie so I do not have to edit the time line. What is the Action Script that I should use?
Right now on the frame I want it to jump from I have
gotoAndPlay(8220);
This does not seem to be doing the job.

I have a preloader working fine but having problems integrating a "skip" button (so users can skip opening animation)Each of the code blocks ("//skip it" and "//Preloader" work ok without each other but when I combine them I get;"Error #1009: Cannot access a property or method of a null object reference. at xyz.fla::MainTimeline/updatePreloader()"I think when the skip buttin is pressed the prelodader code continues to be active???I guess IF skip button is pressed I need to gotoAndPlay (149) and also stop the preloader code but I cannot successfully combine the 2 code blocksHere is the code.
// skip It
orSkip_btn.addEventListener(MouseEvent.CLICK, skipped);
function skipped (evtObj:MouseEvent):void{ trace ("skipped");

I have created an animated home page that I have put a "skip intro" button. When the viewer clicks on the skip intro button I want them to go to the end of the animation/homepage. There are three embedded movie clips of test tubes filling (near the end of the main timeline and these testubes are also navigation buttons to the rest of the site). Even though the viewer goes to the end of the main timeline when they click SKIP INTRO, the testtubes fill at this point and the animation loops back to frame 1 and keeps looping. I want viewer to stay at last frame with all testtubes filled and animation complete. I'm guessing it's something in the individual testube clips AS that is causing this or some simple solution that I'm overlooking? I published an html file and when I tested in a browser and DON'T skip the intro animation it goes through the full animation - to end and stops and does not loop.

I'm creating a flash game which uses time intervals with setInterval and sometimes does heavy calculations. The problem is that on slower machines these calculations can't keep up with the framerate and the movie slows down BUT the timers are unaffected what makes them asynchronous to the movie. Looking back, it was a bad idea to use timers but I can't change it back now. So...is there a way to skip drawing frames?

Game I'm making slows to half the speed when there's a ot going on. I'm sure I'll be able to get rid of a lot of that whe I optimize it, but is there some way of telling flash to skip frames when things get slow?
If not, was thinking I might be able to change the speed of the character so when the frame rate drops to half they get twice as fast.

I'm actually having problems with some AS code. I have a news ticker successfuly adapted from this site, and it's working okay. But I have to add some features I cannot solve by myself, so I 'm asking some help here. My problem is the following :
By what means can I force the Setinterval to be "skipped" (I'd like to add a fast forward/rewind buttons) with a simple MC ? I know a bit about the clearInterval function, but this leads to an akward behaviour of my flash movie (once skipped, the XML is not read in a chronological order� and so on).
The trick is that I I have differents controls type :
- a simple combo previous/next + play-pause buttons
- 4 areas that lead to a particular node (which works partially)
Instead of posting the whole code here, I attach my source .fla + XML (to be renamed as .xml extension is not recognized in the attachments) for you to see how messy is my code (more than partially adapted from the news_ticker.fla used on the tutorials here)

Shouldn't the pre-loader skip and jump to the animation if the intended animation loads? Is this tutorial doing that?
I can't tell if that's happening. My animation is very light but it seems to be going through the entire preloader whether or not the animation is fully loaded or not.

why does my exported .mov file freeze/skip? I exported a .mov if HD 1280x720 and it freezes/skips. If I convert it to another format it's okay. Is it my video card or am I am not exporting it right? I used the h.264 and compressor quality best.

I have a CSV file that's being imported by users. I'm casting it to a string and splitting it up into an array using the line ending. The issue is, inside the quotes may be a line ending that I need to ignore. The RegExp I'm using to split the string is..
private var _newLine:RegExp = /[
]|[
]/;
how to ignore line breaks inside of quotes? or.. Find the line breaks inside quotes to use a replace method
String(myCSV).replace( _yourForumRegExp, "");

how to make my "animation" (more of an interactive slideshow) skip forwards and backwards by two frames rather than one.
Each frame's action starts with stop(); and I know how you can implement the Action script to register keystrokes, the problem is I can't get how to jump by 2 rather than 1 frame at a time.
It would be preferable not to have to use gotoAndStop(#); on every 2nd frame as I have over 350+ frames.

I have created a preloader for a video intro, with a skip button. This preloader is loaded inside the index.html file.When the user skips the intro video, he is forwarded to another page. This part works great.The problem is that if you ever go back to the index.html file after you skip the intro the flash file recognizes that the video is already downloaded, because it is partially downloaded because it begins to download before the user can press the 'Skip' button. I imagine this has to do with the fact that a partial file with the same name exists in cache.When the user clicks on the 'Skip' button I close the loader that was loading the video file like this:
loader.close();
Is this the problem? I thought that Flash automatically compared files.Is there any way to compare the file in cache on the users computer and have the file either resume or redownload if the file sizes don't correspond?
