ActionScript 3.0 :: Set Variable When Event.ENTER_FRAME First Fires?
Jun 12, 2009
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 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?
It doesn't work because "updateNumCsrLoaded" is firing 6 times (twice per image) instead of 3. I could just change the if statement to "if (numCsrLoaded == 6)" but this is not
I'm looking for a way to add an EventListener which will automatically removes itself after the first time it fires, but I can't figure a way of doing this the way I want to.[code]
Tracing the keyCode for the 'a' key (65) only works once for KEY_DOWN events and sometimes KEY_UP behaves in the same way, making development a pain when trying to do things quickly.
Clicking on the stage makes it start working, but why is it just the 'a' key that is affected?
This is on a new MBP running OSX 10.6.5, Flash version MAC 10,1,102,64
[URL]
The issue can be reproduced every time with this code:
I have a block of code that I want to execute directly after a url is known to be valid. What I mean by 'valid' is that the program has checked to see if that filepath actually exists. This could be accomplished by a COMPLETE listener, because after all, a loader couldn't finish loading its content if the referenced file didn't exist, but I want it to happen before any of the bytes begin to get sucked in. I have also tried the HTTPS_STATUS event, with a conditional saying "if the status is this [some non-error status number], then run this block of code." This would have worked great, except that different environments produce different network codes, and some even can't distinguish between errors and non-errors, just returning 0's no matter what. Because of this, I can't write a conditional that works no matter what browser....
I have created a player that loads video FLV files and plays them in a sequence. On loading the videos I retrieve the total video time by stream.client.onMetaData = ns_onMetaData;" and in an EnterFrame event I check whether the video playtime is equal the totaltime. If the video playtime is equal to the totaltime then the player loads the next video. Sometime, even if the video ends, the playtime and total time doesn't match. So to fix the issue, I decided to put an event cue point (END) at end of each video FLV. So whenever the FLV fires the END event, the player removes the current video and loads the next one.
Suppose the video total time is 44:00. The cue point is also at 44:00 in the FLV. So whenever the player gets the END event from the FLV then it loads the next one. Now the issue is, if I pause the video at 42:00 and wait for 2 sec, the player gets the END cue point and jumps to the next video. When I paused the video the timer says "42:00 of 44:00". The timer doesn't increase, that means the video has actually paused. But I still don't understand that why I'm getting the END cue point where the video has not reached the time.
When executing dataprovider.refresh() for a chart component it redraws the chart. How do I determine when the chart is redrawn? I would like to take a png screen shot of the chart when it is fully drawn.
How can I access to an object who fires an eventListener event?
Let's say I have a mc:
var element = new MovieClip();
which has an eventlistener: element.addEventListener(MouseEvent.CLICK, elementEventHandler);
[Code]....
So that is what I want to achieve... Recover the object who fired the event and then do crazy things with it (in this example, add another object in it).
pd: yes, I know I can directly use the var element in this snippet, but in the real code I'm generating the mcs in a loop, according to a xml file.
I have a Loader class which I'm using to load an image:
Code: var request:URLRequest = new URLRequest('https://some website path to .png'); var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, error); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, done);
[Code].....
The code above works when I run it from FlashDevelop but fails when it runs from a website. The domain is protected by a crossdomain file which allows the website I'm calling it from. I've tried other https requests to the same domain using URLLoader and those work fine. This code never calls Event.COMPLETE or IO_ERROR and no alert error comes up.
With the KEY_DOWN event handler, if the user holds the key down it fires the event constantly. I want to create a KEY_DOWN event which only fires once on the initial key press, even if the user holds the key down.
I have an array of loaders loading .jpgs. After the Event.COMPLETE fires, I trace the content at the current page and it tells me the content is null, BUT on testing the images appear just fine. Here's my code:
It seems to be the case that the MOTION_FINISH event fires of prematurely in the Flash Tween class. I've heard that it is not the best tween engine to use, but this seems like a particularly egregious. I am using "Strong.easeOut" for the motion. What are some alternative tween engines that people like?
I added a click event to the stage but this event also fires when i'm clicking a movieclip on the stage.How can i make this event fire only if i click directly on the stage?
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 have multimoduled application and I need to monitor when the mouse is moving or not moving on a protion of my swf file.The app is consisted of video player , text part and video list on the right.So I want monitor when the mouse is moving just over the video player not the whole swf application.I have this function
Code: vidPlayer_mc.addEventListener(Event.ENTER_FRAME, checkMouse); function checkMouse(e:Event):void { if (sw==0) {
[code]....
I use vidPlayer_mc.mouseX/Y; property but i doenst seem to work.I need the functionality when mouse moves over video player the playbar on the bottom shows up and vice versa.
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);
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:
I'm attempting to use the ENTER_FRAME event listener in order to change the text value of a field every 60 frames..I have the strings I want rotated out in an array that is being referenced in the if/else statement The movie doesn't even error out, it just doesn't work.
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?
