trying to build a custom pod for Adobe Connect.
Found some source code, trying to replicate in my code for a simple drag and drop. The error message tells me it's expecting a "right paren before dot" on the third to last line of text below. I've been at this for a few days now with simple errors and I'm just totally stuck!
connector.dispatchSyncMessage("MouseEvent", Expo, true);
connector.addEventListener(SyncSwfEvent.SYNC_MSG_RCVD, mouselisten);
function mouseListen(e.SyncSwfEvent): void {
if (e.data.msgNm == "MouseEvent") {
expo = e.data.msgVal as Array;
}
}

In flash, I created a button and gave the button this code (in AS1-AS2)
on (release)
{
gotoAndPlay(5);
tellTarget("/Anim") //'Anim' is just short form for 'an animation'
{
gotoAndPlay(5);
} // End of TellTarget
}
Since you can't give specific buttons actions in AS3, I gave the button an instance name (the buttons instance name is now 'runButton') and then decided to do this in the actions layer.
runButton.addEventListener(MouseEvent.CLICK, startAnimation);
function startAnimation(event:MouseEvent){
gotoAndPlay(5);
tellTarget("/Anim")
{
gotoAndPlay(5);
} // End of TellTarget
}
but it is giving me an error saying that a '{' is expected after the
function startAnimation(event:MouseEvent):void{
line and it is saying that there is an unexpected '}' on the last line. Any idea how to fix this?
Note: Anim is a movieclip on the main timeline. When I double click the Anim movieclip, it has it's own timeline. I want that timeline to play along with the main timeline, hence the 'gotoandPlay(5) and then the other gotoAndPlay after doing 'tellTarget(Anim').
Use "with" instead of tellTarget. But I do not recommend this at all.
Instead:
this[ "/Anim" ].gotoAndPlay(5);
Similar to Discipol's answer though I think you'll need to cast to a movie clip first:
MovieClip(this[ "/Anim" ]).gotoAndPlay(5);
tellTarget is deprecated since Flash 5. (http://help.adobe.com/en_US/as2/reference/flashlite/WS5b3ccc516d4fbf351e63e3d118cd9b5f6e-7a2b.html)
function startAnimation(event:MouseEvent):void{
runButton.gotoAndPlay(5);
//that slash in the beginning of name (/Anim) I have no idea what to do with,
//basically it used to tell a moveiclip named "/Anim" to "gotoAndPlay" however,
//that is an invalid name so you probably have to change the name of it inside
//Flash unless I'm missing some kind of awesome legacy from old AS1/AS2.
runButton.Anim.gotoAndPlay(5);
}
runButton.addEventListener(MouseEvent.CLICK, startAnimation);
Okay found the answer, turns out I needed to change
tellTarget("/Anim") //'Anim' is just short form for 'an animation'
{
gotoAndPlay(5);
} // End of TellTarget
to just
Anim.gotoAndPlay(5)
and it worked.
I am getting this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Skool_fla::MainTimeline/frame1()[Skool_fla.MainTimeline::frame1:10]
at flash.display::MovieClip/gotoAndStop()
at Skool_fla::MainTimeline/goback()[Skool_fla.MainTimeline::frame2:22]
What is causing this error and how do I fix it?
This is my code for both the frames:
Frame 1: This is the main menu screen where you can access the credit section
import flash.events.MouseEvent;
//setting up the variables
//events
//stop the timeline
stop();
//the play button
play_btn.addEventListener(MouseEvent.CLICK, playani);
function playani(e:MouseEvent)
{
//asking it to progress to the load menu
gotoAndStop(3);
}
//the credits button
credit_btn.addEventListener(MouseEvent.CLICK, creditslide);
function creditslide(e:MouseEvent)
{
//asking it to go the credits frame
gotoAndStop(2);
}
Frame 2: This is where the credits appear
//
//
//all the imports
//events
var credit:credits_bck = new credits_bck ();
var credits_name: credit_nm = new credit_nm ();
var back_butn: back_button = new back_button ();
addChild (credit);
addChild (credits_name);
addChild (back_butn);
back_butn.addEventListener(MouseEvent.CLICK,goback);
function goback(G:MouseEvent)
{
removeChild (credit);
removeChild (credits_name);
gotoAndStop(1);
}
Either play_btn or back_butn is null. Your error message's line numbers don't correspond to your code so it's hard to say. But the gist is you're trying to access a property of something that isn't anything. Check to make sure you're initializing your variables/references properly.
Maybe your problem is Flash bug too.
In my FLA there was a layer with one empty keyframe. If I puted a vector graphics on it, the error was gone. If there was one or multiple MovieClips and there was no vector graphic - the error was there again.
Then I made a new layer and copy pasted all the objects from damaged layer to new and deleted the damaged layer. It solved the problem.
NOTE: Don't copy the keyframes. Only copy the contents.
Now my project is much more complicated and sadly the error came back again.
Test movie frequently and if the error comes back, check the last keyframes and layers you created.
I have been creating a hypermedia player, and i have got to a stage where it is glitching out and it is apparently a...
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at AvalancheCityHypermediaPlayer_fla::MainTimeline/fl_CustomMouseCursor()
Here is my code:
import flash.events.Event;
cust_cursor.mouseEnabled= false;
cust_cursor.addEventListener(Event.ENTER_FRAME, fl_CustomMouseCursor);
function fl_CustomMouseCursor(event:Event)
{
cust_cursor.x = stage.mouseX;
cust_cursor.y = stage.mouseY;
}
Mouse.hide();
I am not sure why it is not working properly, basically when a button is hovered over it is meant to jump to frame 2 and stop, but it is jumping to that frame, and then jumping straight to frame 1 without stopping on frame 2, and stops on frame 1.
1 . Your error isn't producing a line number. You (and I) will find this invaluable for debugging; if in the Flash IDE, you can turn this on in the Publish Settings under swf preferences as a toggle titled "Permit debugging".
2 . Is this code inside a class, or in document code (e.g., Flash IDE "Actions" tab)? If it's inside a class, make sure you pass a reference of the stage to the constructor of your class and assign it to an internally persistent variable so that fl_CustomMouseCursor can address it. By default, classes have no internal way of referencing the stage, and I'm assuming that's what's producing your #1009 error.
For example, inside your class constructor...
package com.example {
public class MyClass {
private var stage;
public function MyClass(arg) {
stage = arg;
}
}
}
And outside when instantiating the class...
var myObj:MyClass = new MyClass(stage);
3 . If you want your code to stop on a frame, use stop(); or gotoAndStop()
4 . Finally, if you're compiling with Flash IDE, you can debug this and see exactly which variable in the stack the runtime environment is having issues with. You can access it from the debug menu or by compiling with control-shift-enter.
I'm currently enrolled in an ActionScript course, and cannot seem to get my progress bar to work correctly. We were tasked with creating a simple image loader application, which would access externally hosted images (through use of a PHP proxy script), and then spit the image onto the user's screen (with a progress event and progress bar to track the image's download progress).
However, when I run it, I get these mysterious black graphical glitches everywhere, as well as a non-functioning progress bar. In some browsers I get the following error: "ArgumentError: Error #2109: Frame label NaN not found in scene NaN. at flash.display.MovieClip/gotoAndStop() at Document/imageLoadProgress().
Here is my code - I cant for the life of me figure out what is wrong. I figure it has something to do with the imageLoadProgress() function, or my progress bar (which is just a simple 100-frame movie clip with a motion tween and a "stop()" command at the beginning).
public function loadImage()
{
var imageURL:String = imageArray[currentImageIndex];
if(loaderInfo.url.substr(0,4) == "http")
{
trace("we're online");
//use the proxy script
//escape() will replace spaces in file names with %20
imageURL = "./image_proxy.php?filename=" + escape(imageArray[currentImageIndex]);
}
var imageRequest:URLRequest = new URLRequest(imageURL);
this.imageLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, this.imageIOError);
this.imageLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, this.imageLoadProgress);
this.imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, this.imageLoadComplete);
this.imageLoader.load(imageRequest);
//end loadImage
}
public function imageIOError(e:Event)
{
trace("ImageIOError called. Error=" + e);
//end imageIOError
}
public function imageLoadProgress(e:ProgressEvent)
{
var percentLoaded:Number = e.bytesLoaded/e.bytesTotal;
percentLoaded = Math.round(percentLoaded * 100);
//this.progress_mc.scaleY = percentLoaded;
if (percentLoaded < 1)
{
this.progressBar.gotoAndStop(1);
}
else
{
this.progressBar.gotoAndStop(percentLoaded);
}
//end imageLoadProgress
}
Your loader script seems absolutely fine to me, except for a tiny flaw:
The only way the NaN(== not a Number) in your error message makes sense to me is if your ProgressEvent's bytesTotal property equals 0 - because division by zero doesn't produce valid results, as we all know.
I can't say for sure why this happens, not knowing any of your server-side code, but I assume it would occur if your PHP proxy script does not set the Content-Length HTTP response header correctly. If you were loading an actual image file, the web server would automatically set the header for you - in the case of your proxy script, it seems you have to take care of it yourself.
Anyway, you can make your loader script more error-proof by testing for NaN, and making sure the frame you jump to is never greater than 100:
var frame:int = isNaN (percentLoaded) || percentLoaded < 1 ? 1 :
percentLoaded > 100 ? 100 : percentLoaded;
progressBar.gotoAndStop(frame);
(I chose shorthand notation, but this is essentially the same as writing two if statements and an else).
Using AS3 / Flash CS4
Alright thanks to everyone who is reading this. My problem specifically I am designing a user interface with controls on it. 5 buttons rotate left, rotate right, zoom in, zoom out, and auto rotate. The interface in itself works fine, I can trace out button clicks, toggle the auto rotate button etc...
My program reads an xml file. Loads some images, fills an array with links for each image, and when the image is clicked a loader loads a swf from a URL and displays it on screen. No problem.
Now I originally had the zoom controls user interface in the runtime_loaded.fla library, and the mouse listeners in the same linked document class. The interface works with the movieClip in runtime_loaded.swf when it is in the same code.
Now to practice good coding, I decided to remove the UI from the runtime_loaded.fla and add it to the Main.fla. This is essential because the main is going to handle possible 100's of images/objects that each have their own unique swf to link too. If I decide to change out the look of the interface but leave the function calls the same, I could essentially put in as many as I want into the main.fla instead of the runtime_loaded.fla which I would have to do for every single object.
THE FILE STRUCTURE
Main.fla <- interface in the library. 5 mouse event functions. Inside each function calls
a property of loaded_swf (loaded_swf.rotateLeft, loaded_swf.rotateRight) etc...
Runtime_loaded.fla <- links specificObject.as in properties (AS3/CS4)
specificObject.as <- has 5 public static functions{ rotateRight, rotateLeft, zoomIn, zoomOut, toggleAutoRotate }
THE CODE
//showFlashBox
function showFlashBox(temp_string:String):void {
if(!flash_box_on){
var temp_top:uint = numChildren;
addChildAt(FlashBoxContainer,temp_top);
newXButton.addEventListener(MouseEvent.CLICK, flashBoxXClick);
1. addChild(new_loader);
2. var url:URLRequest = new URLRequest(temp_string);
new_loader.x = 0;
new_loader.y = 0;
new_loader.load(url);
3. new_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, gotSwf);
flash_box_on = true;
}
}
function gotSwf(e:Event){
4. //loaded_swf = e.target.content;
trace(e.target.content);
5. new_zoom_controls.button_minus.addEventListener(MouseEvent.CLICK, zoomOutFunction);
new_zoom_controls.button_plus.addEventListener(MouseEvent.CLICK, zoomInFunction);
new_zoom_controls.button_left.addEventListener(MouseEvent.CLICK, rotateLeftFunction);
new_zoom_controls.button_right.addEventListener(MouseEvent.CLICK, rotateRightFunction);
new_zoom_controls.button_rotate.addEventListener(MouseEvent.CLICK, toggleRotateFunction);
function rotateRightFunction(e:MouseEvent){
6. //loaded_swf.rotateRight();
}
function rotateLeftFunction(e:MouseEvent){
//loaded_swf.rotateLeft();
}
function zoomInFunction(e:MouseEvent){
//loaded_swf.zoomIn();
}
function zoomOutFunction(e:MouseEvent){
//loaded_swf.zoomOut();
}
function toggleRotateFunction(e:MouseEvent){
//loaded_swf.toggleAutoRotate();
if(new_zoom_controls.button_rotate.currentFrame == 1){
new_zoom_controls.button_rotate.gotoAndStop(2);
}
else new_zoom_controls.button_rotate.gotoAndStop(1);
}
new_loader.contentLoaderInfo.removeEventListener(Event.COMPLETE, gotSwf);
}
If you follow steps 1-6 you see my steps of loading the .swf, mouse event listeners and click handlers, then the object call of the var loaded_swf:Object;
public static function rotateLeft():void
{
object.yaw(animation_turning_speed);
}
public static function rotateRight():void
{
object.yaw(-animation_turning_speed);
}
if I run the main.fla and try to click the buttons. This happens.
ReferenceError: Error #1069: Property rotateRight not found on
ThreedsKU39web and there is no default value. at MethodInfo-82()
ReferenceError: Error #1069: Property rotateLeft not found on
ThreedsKU39web and there is no default value. at MethodInfo-83()
I actually stumbled upon the answer before I finished submitting this as I went through the code to copy it. But after spending a few hours of frustrating moments on this last night, I will post it to ensure the next guy doesn't meet the same demise.
The answer was in the function of the runtime-loaded swf class.
public static function rotateRight():void
{
object.yaw(-animation_turning_speed);
}
It turns out it only needs to be public function instead of public static.
Mainly human error as after the file was working, I attempted to copy the code over to all my other object files, and somehow static got back in there and messed it up. So for future reference when loading in the external swf, public function should do the trick. *Note that many of my variables were returning errors until being declared as public static though.
