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.

I'm using Flash CS6, AS3 to create buttons for my project. Below is my code:
Intro_btn.addEventListener(MouseEvent.MOUSE_DOWN, Intro_func);
function Intro_func(event:MouseEvent):void {
gotoAndStop("Intro");
}
No errors appear when I run it on the output and compiler panel, and the same happens when I run it through the debugger. Also, I have used the exact same code for five other buttons, and they have no problems working. Please can someone tell me what is wrong with my code???
I would need to know more info of your code and the type of buttons you're using, however I would try this steps:
1.- add a Button component from the component inspector, set its instance name, and add that same function to the Click event:
newButton.addEventListener(MouseEvent.CLICK, Intro_func);
function Intro_func(event:MouseEvent):void {
trace("function executed");
gotoAndStop("Intro");
}
2.- run your app and test if the action is executed with this new button. If this test pass, then your problem is your button.
check this on your button:
check the base class of the button (be sure its a MovieClip or a Button class)
check if your button is enabled/disabled.
check if your button or its children has mouseEnabled and mouseChildren set as
true.
check there is no other object on top of the button either in your artboard or added by code at runtime.
I finally would suggest you to set useHandCursor = true; this will replace your mouse pointer arrow to a hand when you move over your button (this is just to test that your button is actually interacting with mouse).
hope this helps.
sorry for the delay, But I've found your solution, It's easier than you thought: your frame is delayed.
your Intro_btn script is on frame 10, however in frame one you're telling it to go to frame 9 (the "Erhu" frame label) so the actions to setup the event listener are never being called.
Also keep in mind the following:
objects exists only in their frames life time, if you have an object from frame 5 to 10, it will only exist in there, so moving to a previous or later frame (e.g. frames 4 and 11) will internally delete the object in memory along with their asociated actions, in english:
you placed the button in frame 10 and added its MOUSE_DOWN listener however, if you go back to frame 0, since the button doesn't exists in this frame it will be deleted from memory along with its listeners, so if you go from frame 0 to any other frame different than 10, your button will never have its listeners associated.
So my suggestion:
1.- add your function into frame 0:
function Intro_func(event:MouseEvent):void {
trace("function executed");
gotoAndStop("Intro");
}
2.- create a new layer. In this layer add a keyframe at the same position where your Intro_btn is(frame 10), and fill the rest of the timeline of this layer with empty frames (no keyframes), finally in the same layer add in frame 10 your listener Intro_btn.addEventListener. this way, the action is available for every subsecuent frame from frame 10.
hope this solves your problem.
I was wondering if someone could share some thoughts about how best to implement an in app loading screen.
I am building a mobile app using Starling and Feathers UI for iOS and Android and some times when a menu item is clicked to go to a new page it takes a few seconds due to the components that are on the stage on the called page. I would like to display a generic 'loading...please wait' screen which will have a message and a loading spinner which will be shown every time a new page is requested.
Thanks
This is how it's actually done, while you're directing your user to the frame, you make the loader MovieClip visible, the loader movie clip is a simple animation, like this:
loader http://www.pockettorah.com/wp-content/app/images/loader.gif
Make a movieclip and in instance name name it loader, and animate it like above
At the top of your code, say loader.visible = false;
In your code, after gotoAndStop/gotoAndPlay or whatever, say loader.visible = true;
There is no real way of displaying this, usually it's just a fake animation that displays while the data is being processed.
Its called a splash screen, it can be a simple jpeg. Adobe help here
I've created a few buttons in Flash. I'm trying to make it so that if you click one button, the audio starts playing for that button. If you click another button, the active audio stops and the new audio of the button you clicked last start playing.
Any help please?
What you're describing is actually quite easy to do.
First things first, I recommend importing the audio into your Flash project. Alternatively, there is a way to play it directly from an external file. This is beyond the scope of my answer, so if you need help on that, you should post a question specifically covering it.
Assuming you have imported the audio file into your Flash project's library, make an as3 instance of it. (Right click the file in the library, click Properties --> ActionScript [tab] --> [Check] Export for ActionScript & [Enter name in] Class)
Now, create a definition of the sound in your code. (Assuming your two sounds were named "mySound1" and "mySound2" in the Class field of the previous step.)
var mySound1:Sound = new mySound1();
var mySound2:Sound = new mySound2();
Now, define your sound channel.
var mySoundChannel:SoundChannel = new SoundChannel();
There are two alternate ways of stopping one sound and playing another. The first is to create one function that does both every time. The second method is to create two formulas, one for "play" and one for "stop". You will need to decide which method works best for you. I'll use the two-function method below:
function stopSound():void
{
//This stops all sound in the sound channel.
//If there is nothing playing, nothing happens.
mySoundChannel.stop();
}
//In this function, we create an argument that allows us to tell the function
//what sound to we want it to play.
function playSound(soundname:String):void
{
mySoundChannel = this[soundname].play(0, 0);
}
[Note, you can tweak the play() properties to meet your needs, doing things like starting in the middle of the song, or looping it forever. 0,0 starts at the beginning, and doesn't loop. See the documentation for this.]
Now you hook up the event listeners for the buttons. (If you need help with event listeners, read the documentation.)
myButton1.addEventListener(Mouse.CLICK, btn1Click);
myButton2.addEventListener(Mouse.CLICK, btn2Click);
function btn1Click(evt:Event):void
{
stopSound();
playSound(mySound1);
}
function btn2Click(evt:Event):void
{
stopSound();
playSound(mySound2);
}
This should be enough information to get you started. In my game core, I actually have a custom class for dealing with sound playback that gives me the ability to repeat sounds, change volume, and keep sounds from conflicting with each other. I say that to emphasize that you can do quite a bit with the sound class. Do some digging in that documentation for ideas and help.
You may also consider putting a try-catch statement in the playSound function, since it will throw an reference error if you pass a name for a sound that doesn't exist.
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.
This may be very simple, but I have no idea how to do this.
I created a photo gallery in AS3, everything is on one keyframe. In this photo gallery I have a link to home. My goal is, when someone clicks the "home" link I want everything to start over. Any ideas on how to do this in AS3?
Appreaciate it.

call flash player container
usually the HTML page and use JavaScript to reload the flash player
flash.external.ExternalInterface.call(jsFuncRestart);
jsFuncRestart is a JavaScript function in the HTML file
and now in the js function just create a new object and replace the current flash object
with the new one
You probably animate everything with as3, right? Then just make a reset function that puts all the images back to their original place and start the animation all over.
