ActionScript 3.0 :: Stops Working If Text Button Is Modified?
Dec 20, 2010
I have a perfectly working text based button positioned inside a movie clip and being called from the main time line.Then I decided to add a color changing effect on the up state of the button. Originally button had a static text for the Up, Dow, Over, Hit frames. As soon as I modified the text into a mc I am getting an error code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at acolyte24A_fla::mainsite_mc_2/frame30()[acolyte24A_fla.mainsite_mc_2: :frame30:4]
Here is line 4 from frame 30:

I have some movie clips that hold the contents. (ie I have a movie clip to hold my navigation buttons and another to hold the actual content.) I wrote some action script on a separate layer that is outside of the movie clips, the AS adds event listeners and a few simple functions. All my navigational buttons work prefectly, I have a button that I use for email, this works the first the frame is loaded. If I go to another frame (another page of the website), and then go back, the button no longer works, I tested with just using trace("the email button was clicked"); oh, I thought I might add that each page of the website is a different frame, that is inside my content movie clip. my AS looks like this:
stop();
navigation_mc.home_btn.addEventListener(MouseEvent .CLICK, homeClickF);
navigation_mc.rates_btn.addEventListener(MouseEven t.CLICK, ratesClickF);

When creating a dropdown for a button, I noticed the dropdown will stop working if the button does not run the entire length of the timeline. i.e.: if you navigate to a page that is out of that button's "range" it will stop working unless reset by returning to the root page. Nesting the problematic button in a movie, however, solves this problem...

My friend and I have been working on a game for about a year. There's a few buttons on the stage that have been on the stage for six months, and always worked fine, but today my friend moved them and I just realized they don't work anymore. They are literally completely unresponsive to all mouse input, they have event listeners for mouseover and click but the events never get triggered (I checked for sure with breakpoints and traces).
I tried the obvious things first; move the buttons to the top layer and set .mouseEnabled = true, but that didn't do anything. I tried moving them around the stage in case something invisible was covering them but that didn't work.
We've got one button instance named "btnSell" that is broken, and another named "btnMenu" that works. They are instances of different objects in the library, but I tried swapping their instance names on the stage; then "btnMenu" was broken and "btnSell" worked.
So I swapped the names back, deleted the broken "btnSell" and created a new instance from the library. Only, it still doesn't work.
My friend deleted a bunch of old and no-longer-used assets, including previous versions of the PNGs that make up those buttons, so maybe that's related to the problem?

I'm trying to make a simple "gallery" that has 6 images, each on a different scene and using 2 buttons to navigate through them. One moves 1 scene right and the other moves 1 scene left.
Everything works except that after I click on any combination of the buttons (left or right) 6 times, it will then only let me move 1 more page as if it no longer has an event listener for the other button.
To clarify a little more:
Starting at scene 1, if I click "right" 6 times and come back to scene 1, when I click right again it will not go to scene 2 again, but if I click "left" it will go back to scene 6 but then once there, it will not go "left" again to scene 5, it will only let me go back to the "right" to scene 1 again. So then I become stuck on these 2 scenes. [code]...

I have a movieclip being used as a button. After a random amount of clicks the button stops working. In other words, the mouse will become a hand when hovering over the button but no clicks are registering to fire the function. I've even clicked it 40 times and it will work but then suddenly, bang!, it stops working. Heres the function that adds the btn, listener, animates it into the screen and also adds text.[code]...

I need to know which part of the text is been modified by the user inside a Flex TextArea. I'm listening to TextArea's Event.CHANGE and my code run on everychange but i don't know what the user have done to the text and it's too long to process it again at every keypress or paste
We are still with Flex 3.5 but i may consider Flex 4 if the solution is easier.

I want to take a static text field, convert it into a button, and use it as a button. I need it static, because I changed orientation, and I do not know how to do that otherwise. The problem is, even though I converted it to a Button symbol, it does not work when I test the movie. It works fine with "Enable simple buttons", but when I test it, the button is not there, no change in mouse cursor, no reaction at all.So this is what I did:
Made text. // static, not selectable, Orientation: vertical left to right, / //rotated; Two filters: Drop Shadow and Glow;
Converted text field to Button - Symbol (scrollBT)
Editing the Button,I put the same content (the static text field) in all four frames: No luck, not working. without the Hit frame filled (which I think doesn't really make a difference): No luck, not working.Tried again, converting the static text field in the button into a Graphic Symbol: No luck, not working.Tried again, and put some differences in the frames for "ON" and "OVER" etc.: No luck, not working.Tried again, duplicating a similar, working button, edited it, and: No luck, not working.
To the button itself and the AS: The button will be a scroll-button for a text field, with different scroll speeds on rollover and press, but nothing else. The code for that I have (I think). It's something like (and please excuse my incorrect syntax here, but I'm typing from memory; still, I use the Script-Assistant and my syntax is apparently correct; it's also working with other buttons):
on {rollOver} {
function (scroll) {
textfieldtxt.scroll - = 1;}[code]....
I'm at the end of my wits. The only difference I can tell from other (working) buttons I did the same way, is that the scrollBt does not do anything except scrolling, while all of the others have frame actions (gotoAndplay etc.) associated with them.

1 main flash movie called game.swf 1 external flash movie called maze.swf
The thing is from my main movie game.swf I load the external "maze.swf" true the LoadClip procedure. This works "fine".
The maze.swf as you can guess contains a maze game, and as you all will know this works with the Hittest commando to check if the character doesn't walk up against the wall.
If I start the maze.swf as a stand-a-lone this works fine, but as soon as I load maze.swf in my main movie. The hittest doesn't work anymore, because in some way the hittest is now checking with the coordinates of the entire main movie instead of only the boundaries of the maze.
I checked If I was calling to the right path, with _root and _level0 and etc. This is al correct because I can trace all the properties from maze.swf in my main movie. But the hittest simply won't work.

I'm trying to set up an app that moves one movie clip to the top of the screen, regardless of where it is or how deeply it is nested. To do this, I take the full path of the movie clip and go in, movie clip by movie clip, putting the depth of each nested clip on top. This part works perfectly. Afterwards, I want to move everything back to where it was. In the first step, I store the current depths of everything in an array before changing depths. In the second step, I'm trying to change everything back to its original depth, as shown in the array.
The code is below:
_global.videoPath = _root.clip1.clip2;
var pathString = String(_global.videoPath);
var videoPathArray = pathString.split(".");
var depthArray:Array = new Array();

I've tried it on several different copies on Flash(on college computers and at home) with different files and no matter what, once I save the file, any action script I had will stop working and will never work again no matter what.
When I create a new document and put in some Actionscript (3), it will work at first. For example if I have one line telling an object to have a lower alpha. Then, consistantly, when I go to "save" it'll stop working.

it's a little ridiculous; and probably unbelievable, but when I have more than five hundred lines of actionscript in tags in my MXML FLEX Main.mxml, all syntax highlighting, error and syntax verification, error reporting, "Problems" pane, and even sometimes compilation fail. Upon removing any chunk of code, it works again.I don't see why Adobe could release a product such as Flash Builder 4.5 Premium, have this big of a problem; and nobody notice. Therefore I believe the problem has to do with my computer, or my project; as there's now ay more people have had this happen if I can't even find it on Google.
Additionally, many objects that have been defined in the MXML properties above the code, even those in All States, are now showing as warning: Access of undefined property down the side of my document. However, these warnings are not showing up in the "Problems pane", and aren't even yellow squigly underlining the right sections of code to pertain to the message.Steps I have taken to TRY and fix this:I have tried restarting, as well as re-installing the IDE (Adobe Flash Builder 4.5).I have tried creating a new projectI have tried splitting my code into smaller .as files and including them.I have tried compiling my application.

In my current flash application I and my co-workers are using Loader to load some SWFs from our server. It works perfectly while we have the flash application on our computers running it trough Adobe Flash CS3 but when we publish it and move the html page to our server and try and run it from there the loading doesn't seem to start. I have the firebug plugin for Firefox so I checked if flash actually loaded the images and according to firebugs network monitor it found all needed resources and downloaded them successfully. But the behaviour of our application is as if the loading starts but the complete event is never sent.

I have this piece of script:
function dataImporting(target, type, path)
{
if(type == "IMAGE")
{
[Code].....
This function is suppose to deal with loading requests from different kind of movieclips throughout the movie. There is something wrong with 'load(path as URLRequest)'. It compiles fine, but upon running flash simply crashes over and over (flash stopped working). It seems as if there is something wrong with it but flash not being able to catch the error.
The path is given as an argument to the function in the form of a string, but should be converted to a URLRequest before being able to be loaded.

I have a flash app that I have been working on for 5 months or so, it relies heavily on Flash remoting with numerous custom classes each making service calls via AMF.I have been developing this app in CS4 on Windows and never had any trouble, it works great.I just got CS4 for my Mac and installed it and copied over the flash files for this app so I can continue working on it on the mac instead of the PC, but on the Mac the app stops working after a few seconds, particularly after doing a few commands that issue flash remoting calls.Even stranger is it will not return to working condition again until I close all of the files involved with the project( the .fla and all .as files involved) and then reload them,if I keep trying to test run the movie from the flash editor it hangs at the first flash remoting call and never returns any error message or any indication that its trying to connect, on the server end my logs show no requests are going to gateway.php.So basically to continue working on the mac I'd have to keep closing down the files every few mins and reloading them.

I am developing a website completely on Flash, it has an option for Fullscreen as well as keyboard navigation to switch between slides. On windows, when i do fullscreen, everything works fine. On Mac machines, after full-screen the keyboard navigation script stops working. This is the script I am using for keyboard action. Is there any particular script for Macs too ?

I've been really frustrated with the code hinting in CS5. It doesn't seem to work like it should. It appears to work fine if I am placing the code on the timeline, but if I create a class file I lose the class code hinting even for simple types like Boolean. The other thing I noticed is after the class file has been created even if I go back to the code on the timeline it has now lost code hinting. The only way to get them back is to close the fla I was working and close flash itself.how to resolve this or is this a legitimate bug? If others have seen this happen please post so that we can get some attention brought to this. It seems to work fine if you create flex components and then edit them in Flash Builder.

Well I have now managed to trace down the problem. It seems as the microphone stops working if I resize my flash application. In other words if I resize my flash application from its original size, the allow microphone dialogue is no longer displayed at the start of the application and the microphone remains muted.
