ActionScript 3.0 :: Triggering A Simple Action With An Enter_frame Event
Sep 9, 2009
I'm struggling to move from AS2 to AS3 and trying to mimic an old AS2 trick. When the playhead hits a frame on my mc's timeline with this code:
_root.gotoAndPlay("3");
the main/root/parent timeline would go to frame 3. Clean, short, simple. How can I do this in AS3?I've tried this code but it didn't work:
this.addEventListener(Event.ENTER_FRAME, proceedNow);
function proceedNow(event:Event){
//parent.nextFrame();
parent.gotoAndPlay("3");
}

Lets say we have a movieclip "Enemy" in the Flash library and a class "Enemy.as" is associated with it which listens to ENTER_FRAME event as follows,
public function Enemy():void
{
//constructor of this "Enemy.as" class

I have a FLV video that I need to stop when my flash video reaches a certain frame. I named my video "SMB3video" Using AS3.
I don't want something super advanced, just keep it as simple as possible.
I tried to create a script which gave me no errors until it reached the frame for the timeline.
Code:
this.addEventListener(Event.ENTER_FRAME,ent_frame);
function ent_frame() {
SMB3video.stop();
}

I have an input text field set to Password and set to a max of 8 characters. When the 8 characters have been typed in to the input field this needs to trigger (without any sort of button action involved) the playhead moving to frame 20 of the timeline.
I have labeled my input field as passwordTxt.

I was having a go at a tutorial which worked fine but then I started seeing how it would work in an external file. Object Oriented Flash. On line 27 it picks up the following error... 1046: Type was not found or was not a compile-time constant: Event. //function enterFrames(e:Event) I've tried this for myself but what are the function parameters I need to mimic the same motion of the bouncing ball?

I just want to make a simple button action using actionscript 2 but I can't get it to work! I'm sorry for even asking but I've been at this for too long now for it to not work I'm using Adobe Flash CS4 and I do the following --
File -> New Flash File (ActionScript 2.0)
Insert -> New Symbol
Name - test
Type - button
Export for ActionScript
Identifier - test
And then draw it in using the keyframes and add the code to 'Actions - Button' for my button
Code:
on(release) {
trace("trace");
}
I click on the button and it animates but no action event in the trace?

I have a little problem while trying to get a URL on a Enter_Frame event using Flash AS3.I would like to trigger the URL request on the last frame of the movieclip.Everything works fine except that instead of getting the URL once, it keeps loading it all the time.
Result: I get hundreds of web pages opening in my browser.
Here is the code I use:
stop();
addEventListener(Event.ENTER_FRAME,my_function);
function my_function(e:Event):void{
var homeLink:URLRequest= new URLRequest("http://www.myurl.com");
navigateToURL(homeLink, "_self");
}

I want to create an endless loop, 8 items moving in a circular shape. When you roll over of each item, it will stop the moving, and you should be able to click it.
I dont know what should I use, should I use Event.ENTER_FRAME or the circular shape should be in movie clip, so that when there is a mouse over event, it will stop moving?
Oh ya, I code everything in AS3, including the movement, objects etc. Something like a new class

I wanna apply a glow filter to a button. What I want to happen is that if for a media player the currentFrame = totalFrame i.e, if the seekBar reaches last frame, I want the next_btn to animate,...like Glow In and Glow Out.
I dont want a mouse_over / mouse_out event to handle the animation.
Possibly I think that I'll have to use a Enter_Frame event, but I cant think of a function to do so.
my glow filter is like this...
var myGlow:GlowFilter = new GlowFilter(0xFE4110, 4, 2, 2, 4,2, false, false);

Variable called "switch" has a boolean value of "false".Event.ENTER_FRAME event listener method fires, and calls method "onEnter()".Within the "onEnter()" method, the "switch" variable is set to boolean "true".My question: What is the best way to make sure "switch" variable is called, and set, only once during the ENTER_FRAME event?
Is it as simple as checking if "switch" is false, and then setting it to true... Does it matter that I would be doing the if() for every frame of the Event.ENTER_FRAME?

I have an ENTER_FRAME event on one of my pages to create a progress bar for an audio track. It is working great, but I when I click on a button to goto the next frame, it continues to run the ENTER_FRAME event continuously. I have many audio tracks in this project and need a progress bar for each. however, once a second one starts, it really begins to bog down the player. Is there a way to stop an ENTER_FRAME event from continuing after you leave a page? Here is the code i have:
Code:
import flash.events.Event;
tb_mc.scaleX = 0;

how to do this, but I was wondering if there is a way to do the following without setting up an event listener for each textfield...
I have a bunch of input textfields on the stage (50+).
I want flash to gotoAndStop at frame 5 whenever ANY of the text fields have something typed in them.
Possible to do without setting up 50 event listeners? Is it possible to just set up one event listener that is trigerred when any input field on the stage is changed?

I am trying to build a simple application. The first phase is selecting to upload a file from the user desktop or from the site's gallery.
The question is if the user chose to upload from the gallery, say, go to an PHP page gallery, choose a photo and then redirected to the Flash app. How would you trigger the Flash up to know there was an image chosen and it should load it?
Does PHP send a variable or create an XML based on a choice and pass it via Flash variable, or does it need JavaScript to tell Flash that if the Flash var is not empty run this function?

This code works fine in my IDE but when I test it in a browser, the Event.COMPLETE function appears to trigger twice. I put a throw error command in to make it show up in Flash debug Player and the error gets thrown twice. I've even done a string search through the code to see if I've added more than one listener but no luck.
ActionScript Code:
private function downloadCompleteHandler(event:Event):void {
_s.removeEventListener(Event.COMPLETE, downloadCompleteHandler); // Clean up
_s.removeEventListener(ProgressEvent.PROGRESS, preloaderBar); // Clean up

My code is contained in a movie clip that plays an animation on roll over and reverses the animation on roll off. The reverse uses a timer that backs up a frame on the each time event. It works for the most part.
Problem: I tried to use watchTimer.stop(); to end the timer. But the eventListener that tracks timer events keeps triggering which I don't want.
Code:
var watchTimer:Timer = new Timer(30);
this.addEventListener(MouseEvent.MOUSE_OVER, foldUp);
this.addEventListener(MouseEvent.MOUSE_OUT, foldDown);[code]....

I'm working on a custom tween class. Everything work good, instead of sound volume.I'm using the following code:
Code:
package {
import flash.events.Event;
import flash.media.SoundTransform;[code]....
It seems that if I use the ENTER_FRAME event for transformation nothing happens.

I have a script that relies on ENTER_FRAME event to run every time. I have noticed on some slower computers there can be some lag when a flash movie is playing. Does ENTER_FRAME run on every frame, even if its on a slow computer? If the flash movie lags, does the ENTER_FRAME event still run and the rendering just try to catch up? Is running code on ENTER_FRAME a reliable way to execute code every time a frame is entered?

I've got a button that, when clicked runs a method. The method waits for a condition to be met (or rather, waits for a variable to be set in the model) and then updates the view. I did this by setting an ENTER_FRAME listener and it works fine:
ActionScript Code:
private function loadHouseRoom(e:MouseEvent):void
{
view.addEventListener(Event.ENTER_FRAME,loadStuff);
[Code]....
I also tried setting the addEventListener to use a weak reference, but the Event never gets fired in the first place.
Note: I have to use a method like this. I removed a bunch of code irrelevant to this question to make this more readable, but the user needs to be able to change his mind and click another button before the loadStuff function is called.

No matter where the EnterFrame event is registered, the frame would not be rendered after the EnterFrame event handler done in each frame.For example, I have two unrelated MovieClips:
Code:
oneMC.addEventListener(Event.ENTER_FRAME, tick);
function tick(event:Event):void {
if (otherMC.currentFrame == 20) {
otherMC.gotoAndPlay(5);
}
}
The frame #20 of "otherMC" will never be rendered on the stage, right?

I use 2 options when i comes to animationg objects with Action Script
1. Timer based animation
PHP Code:
initTimer = new Timer(1000/fps);
initTimer.addEventListener(TimerEvent.TIMER, moveItem);
[code]....
2. ENTER_FRAME event based animation
PHP Code:
var time:int = getTimer();
addEventListener(Event.ENTER_FRAME, moveItem);
function moveItem(event:Event){
[code]....
Both of this options work ideal for my needs and they produce smooth animation. My question is witch one is better and why? And is there more ways to animate objects with action script?

But when I roll over then I rool out and roll over again (not wait until zooming out is completed) the addEventListener does not stop and text is mixed (part pf the text is from first zooming in a nd part of the text ist from second zooming in)
This is my code:

the code below is placed on one frame of the main timeline...it works, but apparently continually triggers the "gotoAndPlay" action over and over again. How can an ENTER_FRAME event be made to play a moive clip such as "staged_kiss_mc" only once?
The playhead on the main timeline rests in this single frame for a while; it would be great if "staged_kiss_mc" were to only play once, when the playhead first enters this frame, rather than apparently repeating continually...is there code to stop this repetition?

I'm attempting to use a custom event and cant figure out what I'm doing wrong.The event just doesn't seem to be either triggering or received.I borrowed the code from the internet, but I only know enough about custom events to sort of figure out what the code is doing.I have a movieclip inside of another movieclip.I need to close the child movieclip when a button on the child mc is pressed.I'm attempting to listen for a custom "close button clicked" event on the parent mc.[code]again...the event just never happens.I never see the output of the trace in the parent movieclip.I do see the output of the trace "OK button pressed" from the child movieclip though.

I've a MovieClip named "Player" that contains three MovieClips (one on each frame): "Idle", "Walk", and "Attack". Idle and Walk are working as intended�when Player is on the appropriate frame, the animation cycles constantly; however, I am having trouble with my Attack animation.I want the Attack animation to only play through completely one time then throw an event so I can resume either the Idle or Walk animation. Is there an event that fires at the end of a MovieClip's timeline, or is there a better way to do this?

This code works fine if the timeline is moving forward through the .flv file. However, the going in reverse produces choppy results. The choppyness seems uniform, as in, it's always choppy and always the same intensity. [code]...
