I am writing a small Flash game using air for android and have encountered a slight issue.
The game has 3 screens (excluding the game screen) which are main menu, load game & create new game. On the load game and create new game screens I want to add a button which take the user back to the main menu.
I know how to add event listeners to buttons but I am wondering where do I bind the event listener for back to main menu, binding in the constructor of my main class produces an error at run time and binding after going to the frame is knocking out the other buttons when back at the main screen.
At present the app is across multiple frames (probably a better structure to this instead of loading a single frame with each menu), I am new to actionscript so I am not entirely certain on best practices for this sort of thing.
Thanks.
I recommend you to use only one frame in your Fla, then use a Document Class. In that main Class, you should place all your display objects using ActionScript.
I hope you know how to instantiate Class as library clips.

I have a flash movie with a interactive game in the middle. The game is a simple drag and drop with a target.
Now to my problem:
When the user plays the game the drag and drop symbols stays in the target spot on the next frame to the end of the movie.
I would like them to disappear after the game is over.
I am a noobie to actionscript 3.0 - is the a code i can implement on the frames after the game to make sure that the objects wont showup.
Thanks..
Frame navigation does not affect objects that were created by code (or even objects that were created by frames but modified by code). So you need to manually remove them via removeChild().
first of all I want to tell that I know there are hundreds of similar questions, but most of them are for projects/games which are built for "on stage development".
I'm using pure as3 approach to develop games. I don't use*main timeline and my project has only 1 frame*.
On my main class's constructor, I only add preloader to the stage.
But still my preloader is seen only when the game is completely loaded.
My question is simple: "Why?" and "How can I fix this?"
-When I try to "uncheck" export as3 on frame 1, flash gives error.(because some of my classes are imported on the main class.)
-Even if I create second frame and put every contents of the game except preloader, the problem is still unsolved.
Thank you very much for spending your time to read this and help me.

To make the preloader, you either need two SWFs or at least two frames. Even FlashDevelop has an ability to use two frames, for this the directive [frame factoryClass="ClassName"] is used in main AS file before public class Main. This is the core limitation of Flash player, that is, it first loads the first frame, and only then it can display that frame. Since you've said you have only one frame, then your game has to be loaded 100% (1/1 frames) before you will see a thing.
There's more - if you are referencing a certain class on frame 1 via its class name, the class with all its dependencies is embedded in the same frame (the first), so you're screwed again. To bypass this, execute stepos 10 through 14 from this instruction to set the frame for classes to be 2 (replace 10 for 2 while executing the instruction), clear "export in the first frame" for all classes except your preloader, and add an instance of game's main class to keyframe 2. Then in preloader code perform proper cleanup and do gotoAndStop(2).
I'm making a multi-part introductory animation for a game. It works when I preview in Flash, but not when I export using the CreateJS toolkit to get HTML5 output.
On my scene's timeline, I have this.stop(); on the first frame, as well as a movie clip that contains several seconds of animation (and which may have to change in length as we develop).
My second frame is labeled "sc2" and I would like the animation to pick up there when the first movieclip is finished. To accomplish this, I went into the first movie clip and put this on the last frame:
_parent.gotoAndPlay("sc2");
This works fine in Flash, but perhaps I can't use the _parent object in JS? Is there an alternative way to access the flow of control or another way to accomplish this? My goal is to avoid doing animation on the main timeline and to control the flow by scripting there so that if the length of the individual sections of animation changes, I don't have to change the start and end frames of the various sections in several places.
How do i get my UILoader to play a .swf file once then disappear until called upon again?
I am creating a guitar tutorial app that shows you chords and the transitions between them. to display the chords I'm using standard Flash graphics and for the transitions i am using a UI Loader to display the .swf files for instance, on the C chord frame, the fingers are in position and the UI Loader is a layer on top of it, when the chord transition is selected from the list component it loads the chordtransition.swf.
The problem is that once the swf is loaded it plays on loop, ive added "stop();" in many different places as people suggest and it doesn't make a difference.
I would like to be able to click "C-D" on the component list then for the .swf to play once then disappear.
Any ideas??
A strategically placed stop() should work (last frame on the timeline in the swf). You'll need to stop the right movieclip - if your movie has nested clips you might be stopping the wrong clip.
However, creating multiple swf's just to show different chords looks like overkill to me.
Create clips showing all chords on the main timeline, and add frame labels to indicate where they start and put stop() at the end of every chord animation (are you using animations?).
Use movieclipWithChords.gotoAndPlay("chord_C");
If you are not using animations you can use movieclipWithChords.gotoAndStop("chord_C");
Of course you can also create labels like 'C' and 'D', and use those as a direct mapping of the chords.
Update: After reading your question again I realize you are actually showing clips of a transition from one chord to another. In that case you can still use my suggestion as above, only your labels will not be for the individual chords, but for the chord transitions e.g. 'transition_C-D' or 'transition_G-B'.
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.
