please can somebody tell me how remote control works? I have to create presentation in Flash platform using ActionScript 3. How to listen keys from remote control to show next slide, prev slide, pause, play etc? Is it like normal keys?
thanks for info
Generally projector remote controls are just left and right mouse click signals. LMB is the 'next slide', RMB is the 'previous slide'.
You're going to run into problems though, since right clicks in Flash open the context menu. Flash isn't really well suited for this purpose as you can see.
I recommend adding your Flash files into a PowerPoint presentation to save yourself all the stress of second-guessing which hardware is available to you.
When programming your flash presentation for use with a remote clicker, do not target left and right mouse clicks.
Instead you need to use keyboard events to target Page Up and Page Down.
The event listener that emulates the remote clicker's forward arrow is:
stage.addEventListener(KeyboardEvent.KEY_DOWN, forwardsFunction);
function forwardsFunction(event:KeyboardEvent):void {
var myKey = event.keyCode;
if (myKey == Keyboard.PAGE_DOWN)
{
The event listener that emulates the remote clicker's backward arrow is:
stage.addEventListener(KeyboardEvent.KEY_DOWN, backwardsFunction);
function backwardsFunction(event:KeyboardEvent):void {
var myKey = event.keyCode;
if (myKey == Keyboard.PAGE_UP)
{
This will allow you to use a remote clicker to work with your Flash presentations. At least this is the case with the Logitech remote I have tested.
Also, I found it necessary to determine the focus for this to work. My Actions were placed on a frame at stage level, ie they related to movieclips placed on the stage. Adding this code to the start of my Actions enabled this to work:
stage.focus=stage;

I'm creating a little developer console for an AS3 AIR application, I'm wanting F12 to add the toggle the display of the console screen but I don't want to litter my program with a bunch of calls to the Console to show or hide it, I also don't really want to be re-creating the console on different screens of my application.
I'm wondering if there's a way or a place I can put my keyboard event to toggle the display that will handle it across the entire application? At the moment I've tried putting it into my Main class which calls the first screen in the hopes that would be able to handle it but as soon as I click on another screen my eventListener isn't called.
Any ideas?
You could add your event listener to FlexGlobals.topLevelApplication instead of specific views, this would achieve the reduction you require
For true application level keyboard handling, attach the listener on the NativeApplication.nativeApplication object.
NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN, toggleDevConsole,false,0,true);
Attaching the listener to the stage will only work when that particular stage (window) has the focus. This will become an issue if your application has multiple windows that require interaction.
For single window applications, either will work.
Woops, I'm not quite with it today!
For future reference I added the event listener to the Stage in my Main function and it's being picked up every time.
stage.addEventListener(KeyboardEvent.KEY_DOWN, toggleDevConsole, false, 0, true);
So, I'm pretty much a beginner in Flash and Actionscript (using AS3, as I said in the title), and I'm trying to make a basic escape the room game. I haven't gotten far, and right now that's because every time I test my game (or publish preview it) the graphics get this annoying outline. Here it is when tested: http://i305.photobucket.com/albums/nn228/chokingondrama/flash.png
Every outline corresponds to some object present in the game, most of which have an alpha component of 0 since they're on different sides of the room. This didn't happen before, but once I added the code that allowed the player to change their view with the arrow (each viewpoint/wall is a different frame) these appeared.
It's a little different when published to HTML, basically it just gives each image a white background: http://i305.photobucket.com/albums/nn228/chokingondrama/html.png
Also, it would be nice if somebody could give me advice on how to make sure importing to flash won't result in lower quality.
Thanks in advance. If needed, I'll post any part of the code.
Some tips:
Don't set alpha to 0, instead use the visible property, setting movieclip.visible = false will make it a lot more efficient.
As for the importing and quality, after you import to stage or library, bring up the library (ctrl + l), and right click on the file you imported, go to properties. If it's an image, set compression to lossless, and allow smoothing.
For audio, go to file-> publish settings, and change audio stream and audio event (whichever you might use) to 128kbps.
As for your main question, I need more info, if you want you can post your source. It might be because of how you are placing your graphics on the stage.
For each of your MovieClips in question:
Try disabling button mode and see if the rectangles go away.
movieClipName.buttonMode = false;
If that doesn't help, or you really want button mode, try setting
movieClipName.tabEnabled = false;
There's a chance that since you added keyboard interaction each of your MovieClips are now expecting to be selected by the user when they press the tab key, much like any normal web form.
tabEnabled in the docs
You could also try
movieClipName.focusRect = false;

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 saw some online flash games can do this:
when you switch your current web to other windows or other web tabs, the application program will draw a black block and tell you've leave the application, click on the flash area to resume .
i've tried some event like focus in and out or mouse leave on the stage,but the reaction isn't what i expected.maybe i use them in the wrong way .please tell me if you got the solution.
var count:int = 0;
this.stage.addEventListener(Event.MOUSE_LEAVE,function(e:Event):void
{
//only be called if your mouse cursor leave the area,but can't detect whether you're actually switch to other program.
trace('mouseleave',count++);
});
this.stage.addEventListener(FocusEvent.FOCUS_OUT,function(e:Event):void
{
//no reaction
trace('focus out',count++);
});
this.stage.addEventListener(MouseEvent.ROLL_OVER,function(e:Event):void
{
//no reaction
trace('mouseenter',count++);
});
There are two methods:
Use Event.ACTIVATE event. But a swf should be on focus before.
Use JavaScript call from ActionScript to check is a window or a tab on focus.
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.
