I have a working Flash movie, using a couple of AS3 scripts. The main stage has some animation going on. My player.as plays some mp3 clips when I click a button. The problem is, the stage animation stops as soon as the sound starts ie. Sound.play() starts, then animation starts again when the sound ends.
The animation is based on
this.addEventListener(Event.ENTER_FRAME,loop3D);
so I gather something happens to ENTER_FRAME due to Sound.play(). What is weird is everything works perfectly on the Flash Test movie (ctrl+Enter). The animation does NOT stop during sound. What to do to make sure the animation goes on always?
There is no inherent problem with playing sound and animation at the same time, nor is there one with combining a (however large) number of class files - you have another problem. There must be an error causing the Flash player to suspend execution of ActionScripts, and it is most probably one of these:
A security sandbox violation.
An IO error or a problem related to playing stuff that has not yet completed loading.
A problem related to loading classes from a separate SWF.
Some other problem causing a null pointer exception.
To debug this, first check your flashlog.txt. If you don't have one, set up the Flash content debugger plugin. See what error codes are thrown, go on from there.

I have a Movieclip for a soldier, who can load, aim and fire a rifle. The animations work fine, but if I put 2 or more of them on the stage, when I run it it immediately crashes flash.
Is there any way to reduce the quality of the Movieclip so that I can have multiple soldiers on the screen without it crashing flash?
I am making a game which requires at least 40-50 of them to be on the screen at once.
Thanks.
Actionscript compiled by external soft crashes when uses symbols with set to false "visibility" attribute after adding this symbol to the stage. But when you compile same code in Flash IDE nothing happens. It's very hard to find.
Try to make all layers except one inactive by setting them "guide" type. Trying one by one you can find this violator layer and faster find sub symbol with switched off visibility.
as you may have noticed just by reading the title it is quite hard to summarize the problem,
which is probably why I couldn't find a solution anywhere.
I am currently working on a flash game using adobe flash pro CC.
I started by creating the first level of my sidescrolling game and got everything to work just as I wanted it to. All my work was on a single frame (frame 1) and on a single layer and it worked fine.
However, when I then went on to move the frame a little further back and added frames in front of it for the menu I encountered a problem.
When I "gotoAndStop" to the frame with my game content on it, everything works except the collision between my character and my objects. My character is now sunk into the "floor object" about have his size, while when i move the frame back to "frame 1" everything works fine again.
I am losing my mind over this. Please help me :(
in flash when you start changing a dynamic property such as x or y, that object will be independent from the keyframe where it originally was ~forever~, even if you go back to the original keyframe. therefore if you start some enterframe and change the playhead afterwards you will get some awkward (but expected) behaviour.
ideally, jump to the game keyframe and just then call whatever methods needed to start the game.
I'm trying to create an EXE projector using flash 5.5 AS3 where I have a few videos (FLVs) to show (their location is right next to the exe file in the same directory) - each load in a different frame, and all of those videos should also have a full screen option to them. Those are original videos that people WILL want to watch in full screen. It's essential for the experience...
The problem(s) I currently have (after fixing the sound that didn't stop after going to a different video) are hard to describe, but I'll try really hard.
Ok, so when I click the full screen button on a video and watch it in full screen, I will eventually want to exit the full screen, so I click on the same icon at the bottom to exit full screen (or ESC button, it's the same) and then click the navigation button to go to the SECOND FLV's frame to watch the other video. After watching the second video in full screen and then exiting full screen, flash takes me to the FIRST video's frame and that is a big problem. Also, now the button that takes me BACK to the second video's frame won't work. It's like flash is stuck.
I use the Components --> FLVPlayback 2.5 from the componant menu (I don't really know AS3 programming) and I fix its properties in the component parameters.
Also, I don't think that any of the followings are the reason for the bug, but I use these 3 scripts to stop all sound when navigating away from one frame (with an FLVplayback) to
another frame with another FLVplayback:
MyFLV.stop();
SoundMixer.stopAll();
MyFLV.addEventListener(Event.REMOVED_FROM_STAGE,xyz);
function xyz(e:Event):void{
MyFLV.stop();
}
I've found these online where people asked help for the sound bug I described.
The third script was suppose to remove the FLVplayback from the stage before going to another frame, but it works only when NOT GETTING INTO FULL SCREEN. I need something that will COMPLETELY remove the previous video from the stage so after exiting the SECOND viewed video, flash won't take me to a video that from some reason is still in its memory. I have something like 30 videos in my project and I need to remove each and every one of them off of the stage before navigating to the next frame to open a new FLVPlayback.
I tried to add a link to a demo I made with the problem so you can look at it, but it triggered a "oops, something went wrong" error, probably anti spam mechanism...
I would recommend using only one frame and only one flvplayback instance. Otherwise you have to deal with weird bugs like the one you are getting (usually caused by misplaced or forgotten code). Of course, using only one frame requires using more code, but with the number of hard-fixes it looks like you were making for the bugs, you may end up with less code.
Don't worry, I'll walk you through everything!
Reasons to use code (as opposed to multiple frames):
Easier to keep track of:
Know where all your code is so you can easily find and fix any problems.
Make changes more easily
You want to switch an existing video? edit a file reference and you are done.
Want to add a video? no more dragging a new flvplayback instance onto a new frame just add some very simple code and a button and you're done.
More customization
Reasons to use multiple frames (and multiple flvplayback instances):
easier to place visually
Some people find it easier when they have an actual movieclip that they can visually place on the stage
Less code
Here we go:
//import flv library
import fl.video.*;
This allows you to use ActionScript to manipulate the flv player
//video playback code-----------------------//
var myVideo:FLVPlayback = new FLVPlayback();
this creates an instance of FLVPlayback called myVideo (referenced from now on in the code as myVideo)
this next chunk shows many of the customizable features of the flv player. It is not necessary to include them.
//places the video player on stage at x,y
myVideo.x = 115;
myVideo.y = -10;
//uses SkinOverPlayFullscreen.swf for controls
myVideo.skin = "SkinOverPlayFullscreen.swf";
//color of controls
myVideo.skinBackgroundColor = 0x333333;
//hide controls and time it takes controls to fade and reappear (milliseconds)
myVideo.skinAutoHide=true;
myVideo.skinFadeTime=300;
//add the player to the stage
addChild(myVideo);
And now comes the important part. I have made buttons and added them to the stage. I gave each of the buttons a different instance name (box1_btn, box2_btn, and box3_btn). When someone clicks on a button, an "event" will occur.
//button listener code-------------------------//
//when button 1 is clicked throw button 1 event
box1_btn.addEventListener(MouseEvent.CLICK, clicked1);
//when button 2 is clicked throw button 2 event
box2_btn.addEventListener(MouseEvent.CLICK, clicked2);
//when button 3 is clicked throw button 3 event
box3_btn.addEventListener(MouseEvent.CLICK, clicked3);
//play different videos for different buttons---------//
//when button 1 event is thrown
function clicked1($e:MouseEvent):void
{
//play video 1.flv
myVideo.source = "1.flv";
}
//when button 2 event is thrown
function clicked2($e:MouseEvent):void
{
//play video 2.flv
myVideo.source = "2.flv";
}
//when button 3 event is thrown
function clicked3($e:MouseEvent):void
{
//play video 3.flv
myVideo.source = "3.flv";
}
This code will not have any sounds that keep playing because two videos cannot play at the same time in one instance of the player. Nor will it have any mess-ups when you come out of fullscreen because there is only one frame for the video to go back to.
Some possible problems you may run into:
It doesn't work at all:
Make sure you have added an instance of FLVPlayback to the library by adding an instance to the stage from the components menu (window>>components or ctrl+F7) and then deleting it from the stage (it should still appear in the library).
The playback buttons I want aren't showing up:
There is a great explanation of how to use As3 to manipulate FLVPlayback here:
http://www.republicofcode.com/tutorials/flash/as3flvplayback/
find the section about "Applying a Skin to the FLVPlayback Component" and follow it to use an adobe playback skin. If you want to make your own unique skin I would recommend opening and editing one of the pre-made skins. I found mine in
C:\Program Files (x86)\Adobe\Adobe Flash CS6\Common\Configuration\FLVPlayback Skins\FLA\ActionScript 3.0
I hope this helps!
Below would be simplest way to unload the FLVPlayback
removeChild(MyFLV);
it works fine for me
flvPlayBack.stop();
removeChild(flvPlayBack);
stops the sound and removes the playback.
I have a simple expandable advertisement which loads an external SWF file. The external SWF file contains an embedded video.
Using the UILoader component, I have loaded the SWF, added it to the stage and the video displays and plays fine.
The main issue is that I have a close button, which should unload the video, and stop it, essentially returning to the default state of the advertisement.
To unload the SWF, I am doing the following:
myUILoader.unload();
removeChild(myUILoader);
When I do this, the video and UILoader disappear from the screen. However, you can still hear the sound in the background, and if I load the SWF again, it creates multiple tracks in the background. Any suggestions?
There are a couple of things that could cause this. One is that the content inside your UILoader is adding event listeners to outside of itself. You can fix this by not allowing it to touch anything outside itself. I believe you can do this by placing it either in its own ApplicationDomain, SecurityDomain, or both. Consult the help for more details.
If this is not feasible, you can try SoundMixer.stopAll(), which will stop the obvious symptom, but will not fix the memory leak you probably have in this situation.
Another possibility, as Ronnie has alluded to, is that you still have a reference to the content of the loader somewhere. If you don't clear that, it will stay in memory.
However, there is another problem that can also cause this, which is that if there is navigation in the movie that skips over a frame that contains a MovieClip with audio set to "stream," the MC will be created but not fully instantiated and will stay in memory with no way to get any control over it or release it. I don't think this is what is happening from your description. If it is, the fix is to make sure that you visit the frame that contains the sound, however briefly, on the way to the other frame. This is actually something you might want to consider even without sounds, because it does occur any time you skip frames in nested MovieClips (you just have no evidence unless you profile the swf), and over time this will create a memory leak.
I have a background MovieClip in a custom button class, which moves the play head to a different frame (via gotoAndStop("framename")) depending on which mouse events it receives.
When the mouse up event is received, it sends the play head back to the "release" frame, where the background should shift back to its original location, but instead nothing happens and the background remains where it was. It's as though Flash is not honoring the background's position defined by the key frame it enters.
The only workaround is to add a frame script to each frame which manually sets the x and y position to what it should be, but this defeats the purpose of using keyframes for the position.
What is going on?
Try calling event.updateAfterEvent(), it's supposed to
Instructs Flash Player or Adobe AIR to render after processing of this event completes, if the display list has been modified.
from here: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/events/MouseEvent.html#updateAfterEvent%28%29
This appears to have been a bug in the Flash IDE, specifically some kind of corruption in a timeline layer.
The corruption originated in Flash CS4, but persisted when opened and compiled in Flash CS5, which is why I suspect it was some kind of content-generation bug, rather than something specific to either IDE version. The IDE probably gets confused when you construct the timeline out of order or drag things around, rename things, copy things in from other files, etc. I think, specifically... it was the fact that I copied this particular object in from another file. And it wasn't even a complex object, it was just a MovieClip that contained a rounded rectangle and had a drop shadow applied, seriously.
Steps I took to resolve the issue were to remove any classes associated with the library item, reverting it back to a standard MovieClip. I then completely removed the problematic layer. I then reassigned the class to the library object and exported it for ActionScript. Finally, I rebuilt the layer from the first frame, adding subsequent keyframes as necessary. I reapplied filters, and adjusted the clips location on each frame.
Now, everything is functioning as expected. The clip's position, filters, etc. are all updated as expected when the playhead moves to any frame. It's working now as expected, so I wasn't doing anything wrong or not possible. It simply must have been some kind of incrementally constructed key framing confusion within the data structures of the IDE. Glad it's working now.
