ActionScript 3.0 :: Preloader Class Timer - Keep Getting Error Message After Simulating A Download?
Sep 21, 2010
I recently switch from AS2 to AS3 (too late - I know) and bump into (probably easy) problems now and then. I'm making this preloader in a class - I read that this might not be a good idea to put it in a class (?) - and I'm using a timer in it. But I keep getting this error message after simulating a download:
Code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at MethodInfo-7()
at flash.utils::Timer/_timerDispatch()[code].........
I made a preloader for this movie: [URL]. But when I simulate a download, it goes straight from 0% to 100% and the bar goes from nothing to filling only half of the screen. I'm using Flash CS3. Here's the code for the Preloader.fla file:
var req:URLRequest = new URLRequest("movie.swf"); var loader:Loader = new Loader(); var nPercent:Number; loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, preLoad); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, fileLoaded); [Code] .....
The graphic for the preloader is made up of two parts. background_mc is the light blue background for the progress bar and bar_mc is the dark bar that's supposed to fill it up.
I use fileReference.download() to download files. The fileReference send request to java servlet.In servlet, some error may be checked. For example error - 'File not found'. I want to send the error to flex side. I tried lots of methods,but fileReference in flex can't receive them.Such asresponse.sendError(HttpServletResponse.SC_NOT_FOUND, "File not found");r PrintWriter out = resp.getWriter(); out.print("File not found");It seems fileReference can't triggers event 'DataEvent.UPLOAD_COMPLETE_DATA' and'HTTPStatusEvent.HTTP_STATUS'.
In the main class (DocumentClass) I have the following code to set up the preloader:[code]Although I am not getting any error messages, I have a strange issue going on where the first frame stays blank until the last second then flashes the preloader before going on to play the game.If you change the code "loadingPercent.setValue" to just "trace" you will notice that the game isn't even keeping track of the first 90% of the loading going on.
I'm trying to catch a Sound class error. The error message that I want to catch is Error opening URL 'file:///E:/blablaFolder/sound.mp3'. So far I'm in this code block: ActionScript Code: var error:Error; try { _sound.start(); } catch (error:Error) { trace("error--> "+error.toString()); }
im getting an error message that flash cant find the base class. i put the as file and the fla file in the same folder, isnt that the first place in the classpath?
button1_btn.addEventListener(MouseEvent.CLICK, showimage1); function showimage1(event:MouseEvent):void { gotoAndStop(1); }
This is my script (with more buttons done the same) to have the user click a button and a new photo appears, but the movie just runs continuously. I get an error message saying "The class or interface 'MouseEvent' could not be loaded.
i am writing script for a preloader and when i come to compile the script for testing i recive this error message: The class or interface 'Event' could not be loaded.
When opening a fla - made in cs5 - in flash cs 5.5 a message asks if I agree that the file will be converted to cs5.5. I agreed to the conversion and saved the file.When opening this "converted" fla I get an output error message: #1014: class fl.video::UIManager could not be found.The file is 08End.fla from Classroom in a Book Lesson 8.
I am attempting to use a simple preloader that I've used many times in the past but am now receiving an error. The difference this time is that I've created a Class as opposed to just placing all of my code in the the time line.
[Code]....
When I publish the file, I get the error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at game() Everything runs perfectly fine when i publish the file not using any preloader.
I am attempting to use a simple preloader that I've used many times in the past but am now receiving an error. The difference this time is that I've created a Class as opposed to just placing all of my code in the the time line. I've placed the following code in the timeline of my preloader movie and am attempting to load the SWF of my main movie, which uses an external class for all of its code.
how to make a dynamic unfilled and filled circle. that will take input from a slider to dertermine how much of the circle is drawn. I wanted to use this for a preloader. Unlike the author I would like to use it inside of a document class. I am getting 1061: Call to a possibly undefined method createEmptyMovieClip through a reference with static type document. and 1120: Access of undefined property circ1. The second is caused from the first. How would I get this to work in my document class?
//original code // x: circles center x, y: circles center y // a1: first angle, a2: angle to draw to, r: radius // dir: direction; 1 for clockwise -1 for counter clockwise
I have buils a flash movie using a document class, all works fine. When I load the movie using a preloader all reference to the stage as in stage.scaleMode = StageScaleMode.NO_SCALE; or stage.stageHeight throws a TypeError: Error #1009: I think i undrestand the problem, I am no longer accessing the stage properties. How do i access stage properties from the document class once loaded into the prelaoder?
I am trying to and I have the following message error:"the video player is in the connection error state. It enters this state when a video stream attempted to load but was unsuccessful. There are two possible reasons for the error: no connection to the server or the stream was not found."
I've created some error handling for external images loaded via a path in XML. Within the Flash preview it's fine and shows the full error message (and most importantly, the URL that isn't loading).
But in the browser, even locally, it doesn't out put this message!
Here's my code:
function loadIOError(event:IOErrorEvent){ errorLog+=event.text+' '; }
#1006: value is not a function. at MethodInfo-43() I don't know what the problem is, or where could it be, here is the problem code, but first a brief description: Every 3 seconds 3 enemies will be created with a random position, the enemies can't be appearing on top of the other so I check if they collide with any previously added enemies, if they do I assign other random coordinates and check again until there is no collision (I'm using the collision detection kit CDK for the collisions[URL]..the first 3 enemies appear correctly but afterwards the error appears and the next time the program enters the generation part the enemies begin appearing in ridiculous numbers.
i am new to flash (yet i have been using it for years) by that i mean, i struggle with it a lot. i was hoping someone could help me with the "incompatible override" error message and the "duplicate function definition" message.
i am currently trying to learn ZendAMF, but i have a hard time troubleshooting which makes learning it quite hard. Is there a way to make the PHP file throw an exception that gets traced as an error message in AS3 (not Flex), the only error i seem to be able to get is "Error #2044: Unhandled NetStatusEvent:. level=error, code=NetConnection.Call.Failed", but it tells me jack ****.
i have gotten ZendAMF working, i just want to know how i can make error handling better, so that as an example can use PHP to tell flash that no results were found, or that the typed text was invalid. Is it better to use AS3 to check if the field was filled properly?
I'm using Flash CS5 with AS2. However, there's this project I'm working on right now. When I simulate a download, the preloader is somehow skipped. I'm staring at a blank screen for a minute instead of a preloader and then the main menu pops up. You just see the preloader for one single frame.
Now the code for my preloader is really the standard code: Actionscript Code: stop();onEnterFrame = function(){ p = getBytesLoaded()/getBytesTotal(); percent_txt.text = String(Math.round(100*p)) + " %"; if(p == 1){ nextFrame(); delete onEnterFrame; }}
I have some code on frames 2 and 3, but I tried to see what would happen if I left it out, and the same thing occurs regardless of there being code on frames 2 and 3. All I can really tell you that may mean something is the file size is 2.9 MB. Why Flash Player doesn't just display the preloader, especially since I've never encountered this before.
how a download is simulated to be able to test the preloader. I tried view>Download settings as stated in the help file, but I couldn't find download settings under view. My Flash version is "flash CS3 provessional, version 9"
I've been searching through code FOREVER and can't find anything helpful or functional yet. Right now I have a page that downloads a file to the user's computer when you click a button. But, I want to create a loader so that the user can follow the progress of their download as well as a way to go to the next frame on the main timeline when the download is complete.
I know how to setup a preloader and I have that working. But when I debug the flash application and simulate a download, it has a blank background until a few seconds have passed. I know it is "downloading" the swf file and I'm wondering if I can show a progress bar for that, or do I need to have the swf file as small as possible and pre load everything needed and have all assets as a separate file I fetch? I found something with ProgressEvent.PROGRESS but this only loads after the flash file is finished downloading.
I followed a tutorial on gotoandlearn.com and followed it to a "T," yet cannot troubleshoot this myself. I built a simple preloader in AS2, but when I simulate the download for a Flash website in Adobe Flash CS4, all I see is a white screen, then it continues to the website. I previewed the bandwidth profile and I can see that it's working it's preloading magic; I just can't see the animation.
I looked through numerous forums and I am not using an components that are exported to the first frame -- at least that I know of. Has anyone experienced the same issue?
I would like to create a preloader type effect for when my Image gallery changes images. I have a timer that runs my function "changeFrames" that just MovieClip(root).nextFrame(); . out or point me to a good source for creating this preloader type effect based on a timer. I would like to show a progress bar that when it reaches the top will be when my timer is up and the changeFrame function starts. I could make a movie clip of a load bar that lasts the same amount of time as my timer but I would have to create many different load bars this way because some of my frames pause longer than others.
I've been working on some actionscript 3 system. And all of a sudden, it wouldn't execute anymore. When I pushed CTRL-Enter in Flash CS3, a white screen would open up (instead of the normal flash program) and no trace-output would be given.
Three hours later I found the cause of this weird problem.It's (simplified) the line:
var value:Number = -(true ? 1 : 0); // This one doesn't work.
Put this line in your script, and your entire program won't execute. And without any error message! I was wondering, why is that? By the way, the following lines do work[code]...
I am building a calculator which recommends battery chargers based on the value the user inputs. If the user inputer letters instead of numbers (including spaces) the numeric result displays as NaN, is there any way to create an error message which pops up when the result is NaN and tells the user what they did wrong I have tried [code]where ampSuggest is a numeric variable that is the resulting number from the users input and wrongInput is a one frame movieclip.This method gets no error messages but doesn't seem to actually do anything.
