I am using ActionScript 2.0, but I think in this case the difference is small.
I have created a scene with a symbol inside which there is a timeline and export it for actionscript with class name "def". I want to play sound only on specific frames of "def", but it continues to plays on other frames.
My code:
soundsamp = new Sound(this);
soundsamp.attachSound("soundsamp.wav");
soundsamp.start();
soundsamp.onSoundComplete = function(){
if (def._currentframe <= 8){
soundsamp.start();
}
}
if (def._currentframe > 8){
soundsamp.stop();
}
Why it is not working?

I'm using Lance for a game where the gameplay area is a tiled map. When a player presses the left-arrow key, their character should move one tile to the left, etc. I tried two approaches, see below, but got neither to work.
Could either approach be modified to work with tile-based movement? Or is a third approach needed? Or is Lance not suited to this kind of game?
Approach 1: Adjust the player's position directly when a key is pressed. From my GameEngine class:
if (inputData.input == 'left') {
player.position.x -= 32;
player.angle = 180;
}
While this works well for a single player, it doesn't in multiplayer. When player A moves, their position is not updated on player B's screen.
Approach 2: Set the player's state when a key is pressed:
if (inputData.input == 'left') {
player.state = 'walkLeft';
}
Then add a postStep handler in the common GameEngine class. (Adding it to Player didn't work). This code turns the player (over many steps) to face 180 degrees and then accelerates the player in that direction:
onPostStep(event) {
let players = this.world.queryObjects({instanceType: Player});
players.forEach(player => {
if (player.state == 'walkLeft') {
if (Math.abs(player.angle - 180) > 2)
player.turnLeft(2);
}
else {
player.accelerate(1);
player.state = '';
}
}
})
}
With this approach, if a player presses the left arrow key, their angle changes as expected at first, but the acceleration and movement is erratic. Also, Player A's position appears different on their screen vs the screen of Player B.
The Spaaace demo is the base for my project, so my project uses the same bending, physics engine, etc.
The first approach is better. The Brawler game in the sample collection does exactly what you describe. You can look at the BrawlerGameEngine.js code in https://github.com/lance-gg/tinygames/tree/master/brawler
Make sure that the action is processed in the method
GameEngine::processInput(inputData, playerId)
i don't know how actionscript get all speakers' name, how actionscript can do this？
i know actionscript can get microphone name list by using Microsoft.names
but how to do for speakers ?
like the skype, it can specify which speaker to ring, but how actionscript to implement the same function
I'm assuming you mean the left and right speakers? If that's the case, use the SoundTransform class and the pan property:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/media/SoundTransform.html
Using a value of -1.0 will mean that your sound will play out of the left speaker, while a value of 1.0 will mean that your sound will play from the right speaker. This is what Skype is doing from what I can tell.
// create our sound and play it, storing the SoundChannel created
var sound:Sound = new Sound( new URLRequest( "../assets/myMusic.mp3" ) );
var channel:SoundChannel = sound.play( 0, 10 ); // loops 10 times
// create our SoundTransform object
var st:SoundTransform = new SoundTransform( 1.0, 0.0 );
// add a stage listener for mouse click - we'll take the x position of the click
// and use it to set the pan
this.stage.addEventListener( MouseEvent.CLICK, function( e:MouseEvent ):void
{
// sets the pan between -1.0 and 1.0 depending on where on the stage
// important - we need to set the soundTransform property on the
// SoundChannel for our change to take effect
st.pan = -1.0 + ( e.stageX / stage.stageWidth ) * 2.0;
channel.soundTransform = st;
trace( "Set the pan to " + st.pan );
});
I'll start off by admitting that I am a beginner to ActionScript and I am in the process of coding my own basic arcade game (Similar to that of the old arcade game "Joust"). Whilst I have been able to code the sprite's movement I am looking to make the sprite flip to face the other way when I press the right arrow. I figured either I could try and rotate the object around its axis (Which I've tried multiple times and has proved difficult) or I could try and "Replace" the current sprite with another sprite (Which is just the sprite facing the opposite way). I've searched everywhere for a method of replacing a sprite with another sprite but to no avail. How would it be possible to give this sprite a flip effect when a certain keyCode is used?
Try this simple code below. Here 'object' is the movieclip/sprite that you want to flip
stage.addEventListener(KeyboardEvent.KEY_DOWN, OnKeyDown);
function OnKeyDown(event:KeyboardEvent):void
{
var uiKeyCode:uint = event.keyCode;
switch (uiKeyCode)
{
case Keyboard.LEFT :
object.scaleX = -1; //flip
break;
case Keyboard.RIGHT :
object.scaleX = 1; //unflip
break;
}
}
NOTE: If you want the movieclip to flip without any shift in its position then the movieclip must be horizontally center registered.
Tell me if this works for you.
Are you using as2/as3? you could flip the axis Y 180 degrees
if your using as2 you will need to either mirror the bitmap via actionScript or
add a second bitmap that is mirrored to the display list.
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressedDown);
function keyPressedDown(event:KeyboardEvent):void
{
var key:uint = event.keyCode;
switch (key)
{
case Keyboard.LEFT :
myMovieClip.rotaionY = 180; // MC will be mirrored
break;
case Keyboard.RIGHT :
myMovieClip.rotaionY = 0;
}
I'm creating an app for iOS (mainly) in Flash CS6 and I'm having a few problems with getting a particular page to work.
The layout is as follows: I have a movie clip that is 3 times the width of the stage with my content, with the instance name of txtContent.
On a separate layer, my Action Script (v3.0) reads as follows:
import com.greensock.*;
import flash.events.MouseEvent;
//Swipe
Multitouch.inputMode = MultitouchInputMode.GESTURE;
var currentTile:Number = 1;
var totalTiles:Number = 3;
txtContent.addEventListener(TransformGestureEvent.GESTURE_SWIPE , onSwipe);
function moveLeft():void{
txtContent.x += 640;
}
function moveRight():void{
txtContent.x -= 640;
}
function onSwipe (e:TransformGestureEvent):void{
if (e.offsetX == 1) {
if(currentTile > 1){
moveLeft()
currentTile--
} else {}
}
if (e.offsetX == -1) {
if(currentTile < totalTiles){
moveRight()
currentTile++
}
}
}
stop();
When I test the movie, with a touch layer, the movie clip successfully moves left and right for each swipe, and does not continue to move too far in either direction, in effect ignoring any other swipes.
However, when I compile the IPA and test on the iPhone, only the first two "tiles" move (I can only see two thirds of the movie clip with swiping), as if I swipe to the third "tile" I cannot swipe back at all. No matter what I do, it gets stuck on that third section.
Is there a problem in my code that isn't registering properly in iOS?
FYI, I'm testing on an iPhone 3GS.
It was my own mistake - the final 'page' of the slides did not have a large background with the alpha set to 0% like the others, therefore to slide it back it would only work when holding the text (which was small). With the addition of the background, the movieclip is solid and therefore swiping the whole screen worked fine.
I'm using openCV to split a video into frames. For that I need the fps and duration. Both of these value return 1 when asking them via cvGetCaptureProperty.
I've made a hack where I use AVURLAsset to get the fps and duration, but when I combine that with openCV I get only a partial video. It seems like it's missing frames.
This is my code right now:
while (cvGrabFrame(capture)) {
frameCounter++;
if (frameCounter % (int)(videoFPS / MyDesiredFramesPerSecond) == 0) {
IplImage *frame = cvCloneImage(cvRetrieveFrame(capture));
// Do Stuff
}
if (frameCounter > duration*fps)
break; // this is here because the loop never stops on its own
}
How can I get all the frames of a video using openCV on iOS? (opencv 2.3.2)
According to the documentation you should check the value returned by cvRetrieveFrame(), if a null pointer is returned you're at the end of the video sequence. Then you break the loop when that happens, instead of relying on the accuracy of FPS*frame_number.
