Would like to be able to play a sound from the navigation helper class (after back button handling). Can play from a page, but can't seem to figure the logic on playing from a class with no visual elements.
Use the the following code in the page where the user would press back button:
HardwareButtons.BackPressed += HardwareButtons_BackPressed;
In the event make the checks and play the sound and make
e.Handled=true;
this prevents the back navigation(to prevent the navigation while the sound is still playing)
When the audio has finished playing remove the handler
HardwareButtons.BackPressed -= HardwareButtons_BackPressed;
and invoke
Frame.GoBack();
Hope it helps :)

I am trying to figure out how to implement a pause screen on background. In my game scene I have a method called pauseGame. I set this up so that the user can click on pause button while playing and menu comes up asking them if they want to resume or go to main menu. Now when the phone goes into the background I want to also call this same function in my game scene so that it will show that menu so that when the user comes back to the app they will be able to resume instead of it automatically starting. I have googled for hours now and tried a few things but the only thing I am able to come up with is to call the directors pause() method from the app delegate. Which is what is happening any way but I need to call the pauseGame method of my game scene. Is there an event that I can listen for in the game scene or is there a way to call my pause from the appdelegate. I just cant seem to find an answer for this one.
App Delegate has this function, void AppDelegate::applicationDidEnterBackground(), which gets called every time app enters background.
You can access current scene by using this,
Director::getInstance()->getRunningScene(); cocos2d-x 3.0
CCDirector::sharedInstance()->getRunningScene(); cocos2d-x 2.x //Not entirely sure of the syntax, pls to check
After right typecasting and importing the appropriate header file, you can call required function from here.
Also,
AppDelegate also has, void AppDelegate::applicationWillEnterForeground(), which gets called every time app enters foreground.
Alright I've managed to make an almost web page style thing in flash. I have all the coding to navigate the pages finished, but now I'm having the issue of when I change pages my main page music continues while the other pages music begins. I.,m unsure of how to code this. can anyone help? also I already have click sound effects going for my buttons and they seem to be working fine. Don't know if that helps at all. I'm also using flash cs6 and don't want to go to cc, because the removal of the bone tool.
To stop a sound, you will need to use a SoundChannel object when you tell the sound to play. Then, with the reference to the SoundChannel, you can stop the sound before you exit the section.
// save this reference for later so you can stop the sound when you want..
var mySoundChannel:SoundChannel = mySound.play(); // Get a sound channel.
// Call this later
mySoundChannel.stop();
Without a SoundChannel to control it, the sound object will do its default behavior, which is to play to completion.

I made a .swf Application which goes automatic to the fullscreenmode with the functions
stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
stage.scaleMode = StageScaleMode.NO_SCALE;
So what i wanted to do is to start a .flv video and in front of this .flv include, i want to have a Movieclip, which is in front of the .flv Video.
That doesn't work, in the Fullscreen mode. If i minimize the windwow. The Movieclip goes in front of the flv- included video.
So what i need is, to have something like a z-index function in the fullscreenmode.
Can anybody help me
Thanks
Flash Player: 11.4
Assuming you have a reference to every Display Object, you could use swapChildren to swap the depth or the z index:
var index1=this.getChildIndex(child1);
var index2=this.getChildIndex(child2);
this.swapChildren(index1,index2)
where child1 & child2 could be any display object including video player.
I'm not in front of Flash right now so I can't test the problem but I'm sure its considered bad practice to have an app that goes auto-fullscreen by itself on loading. Adobe considered it a security risk and they may have taken security steps that conflict with what you're doing... just a guess though.
"That doesn't work, in the Fullscreen mode. If i minimize the windwow.
The Movieclip goes in front of the flv- included video."
My advice is to make a button somewhere on the screen for going in/out of fullscreen. So when it looks okay in the window mode, click that button to go fullscreen again and then tell me if its okay now or is the problem still happening?
A) If its okay then you need to lose auto-fullscreen and just start with a button on stage. Give it text label like "Start App" or something like that so users know what to do (much better than just throwing them in fullscreen with some unexpected loud video etc).. Anyway when in fullscreen thats when your function should addChild the flv container MC and then your other MC. Use removeChild commands when F.S mode is exited. Make the "Start" button visible or hidden depending on screen mode (F.S is hidden, Window is visible etc).
B) If its not okay you have other problems.. I'm off to sleep but will check later if there's a reply. Peace..
I made my own solution :
var container:Sprite = new Sprite();
container.addChild(logo);
container.addChild(startVideo);
container.swapChildren(logo, startVideo);
this.addChild(container);
Whith this Sprite object it works fine.
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'm creating a DDR-like game for an assignment and my keyboard seems to respond and trace it, but only if I press on the screen with the mouse first.
How can I get rid of that and just have it respond right away?
right_mc is the arrow that's moving
ArrowRight_mc is the arrow at the top
perfect_mc should pop up briefly
and so should a glowing arrow where it hits.
Here is what I have so far:
if(rightDown){
trace("right arrow");
if(right_mc){
if(right_mc.y >= ArrowRight_mc.y){
perfect_mc.visible = true;
glowRight_mc.visible = true;
}
}
}
This has been a long standing issue for Flash developers. Flash needs keyboard focus before it can detect keyboard events.
The problem is that the browser does not give focus to the SWF until the user clicks somewhere inside the SWF. This does make sense though. I don't want the web page I am on to lose focus just because there is a flash movie embedded somewhere. This is a security feature, to stop things like Flash banner ads being silent key loggers. However there are some instances that it makes sense to force the focus e.g. a Flash game where its the only thing on the HTML page.
Usually the best thing to do is have start menu screen with a "play" button. This forces the user to click on the SWF without even knowing about this "focus issue".
There is more info at the Adobe Technote - Giving keyboard focus to an embedded Flash movie.
***EDIT****
Whether the Flash has focus or not, only affects keyboard events. It will not affect code from running, movieclips from playing, or sounds/video from playing.
The issue here is that the embedded SWF file does not have focus when the screen first loads. You can assign focus to it using JavaScript but in my experience, this does not always work 100% of the time because of variations in the way browsers interpret JS. What a lot of people do is have a big START button following the load of the game so that players have to click on the SWF to begin playing. Some sites, even use JS to detect when the game has lost focus and will pause the game and alert the user.
I suppose I haven't exactly answered your question because I'm not that great at JavaScript but I hope this points you in the right direction.
In response to your comment...
I'm unclear on something. If you have to click to start the song then you've already clicked on the SWF and you should be getting keyboard events, right? So if you're having to click to start then click again, maybe you need to make sure your mouse listener is at the root of your display list.
// in your document class / main AS file...
this.stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown);
Or perhaps you need to poll for input during an EnterFrame loop rather than listen for key events.
I know what you mean. You have a specific object on the stage that needs focus before keyboard events will trigger. I'm having the same issues with a game here. A sprite needs to move with the keyboard arrows but the container needs focus so it will respond. I'm just setting the object I want to move to be tabEnabled as my requirements are only for accessibility purposes so tabbing to the object first will give it keyboard control.
