I have a Timer, and when the time expires it goes to another scene. When you move the mouse, Timer gets reset. However, when time expires (and it goes to the other scene) and I go back to the first scene (via clicking the on the stage of the other scene), my timer mouse event no longer works. The time does not get reset, and instead time expires and goes to the other scene again. I put a trace in my MOUSE_MOVE event method so I see what is going on in there, and the time is just not being reset. Can anyone help?
Here is my code:
//Define, Set and Start Timer
var myTimer:Timer;
myTimer = new Timer(10000, 1);
myTimer.addEventListener(TimerEvent.TIMER_COMPLETE, onTimerComplete);
myTimer.start();
//Mouse Move Events, Reset Timer when you move the mouse
stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoved);
stage.addEventListener(TouchEvent.TOUCH_BEGIN, mouseMoved);
//Timer Complete Method
function onTimerComplete(event : TimerEvent) : void
{
gotoAndStop(1, "Screensaver");
}
//Time Mouse Move Method, Reset Timer when you move the mouse
function mouseMoved(event:MouseEvent):void
{
myTimer.stop();
myTimer.reset();
myTimer.start();
}
And here is the click event on my screensaver scene:
stage.addEventListener(MouseEvent.CLICK, stopScreensaver);
function stopScreensaver(e:MouseEvent):void
{
screensaver1.visible = false;
screensaver2.visible = false;
screensaver3.visible = false;
screensaver4.visible = false;
screensaver5.visible = false;
screensaver6.visible = false;
screensaver7.visible = false;
screensaver8.visible = false;
touchStart.visible = false;
timer.stop();
timer.reset();
stage.removeEventListener(MouseEvent.CLICK, stopScreensaver);
timer.removeEventListener(TimerEvent.TIMER,timerListener);
stage.removeChild(whiteBackground);
gotoAndStop(1, "Home");
}

Turn off when the programa is not touched for 5-10 minutes.
I am using timer
Even when the program is touched, it closes when the time is up
How can i solve it?
var myTimer:Timer = new Timer(300000);
myTimer.addEventListener(TimerEvent.TIMER, timerListener, false, 0, true);
function timerListener (e:TimerEvent):void{
fscommand("quit");
}
myTimer.start();
myTimer.reset(); reset it and then start it again myTimer.start(); you just have to put that in some event handler that indicates "activity" - perhaps every n time to keep it from firing a lot
var myTimer:Timer = new Timer(300000);
myTimer.addEventListener(TimerEvent.TIMER, timerListener, false, 0, true);
function timerListener (e:TimerEvent):void{
fscommand("quit");
}
myTimer.start();
I won't dive into the custom event class but there are a good number of sources for that but basically use the .reset() and .start() in those.
For example
https://gamedev.stackexchange.com/a/12230
https://stackoverflow.com/a/23559690/125981
Here is a simple example to study...
var myTimer:Timer = new Timer(300000);
myTimer.addEventListener(TimerEvent.TIMER, timerListener, false, 0, true);
stage.addEventListener(MouseEvent.MOUSE_MOVE, reset_Timer); //check for any mouse movement
myTimer.start();
function timerListener (e:TimerEvent) :void
{
//# function happens when Timer amount is reached (eg: mouse did not move to reset it)
//choose one below..
//fscommand("quit"); //# close app
//myTimer.stop(); myTimer.start(); //# stop and then restart Timer
//stage.removeEventListener(MouseEvent.MOUSE_MOVE, reset_Timer); //# cancel any further usage of this function
}
function reset_Timer (e:MouseEvent) :void
{
//# function happens after mouse not moved for total millisecond count of Timer amount
myTimer.reset(); //reset countdown because mouse was moved
}
I am a new new person who learn action script 3.
i have problem when i convert keyboard event to mouse event when i moving a walking character.
when use the keyboard event i have no problem. this is my code
import flash.ui.Keyboard;
var speed:Number=2;
stage.addEventListener(KeyboardEvent.KEY_DOWN, stikman);
function stikman(e:KeyboardEvent)
{
if (e.keyCode==Keyboard.LEFT)
{
stik.x-=speed;
stik.scaleX=-1;
stik.stik2.play();
}
else if (e.keyCode==Keyboard.RIGHT)
{
stik.x+=speed;
stik.scaleX=1;
stik.stik2.play();
}
}
and then i try to change keyboard event to mouse event when moving character with button it should press click, click and click. i want to hold the click when moving the character and when mouse up the character stop. but i still don't know how. this my code when i try to change to mouse event
var speed:Number=2;
mundur.addEventListener(MouseEvent.MOUSE_DOWN, stikman);
function stikman(e:MouseEvent)
{
stik.x-=speed;
stik.scaleX=-1;
stik.stik2.play();
}
maju.addEventListener(MouseEvent.CLICK, stikman2);
function stikman2(e:MouseEvent)
{
stik.x+=speed;
stik.scaleX=1;
stik.stik2.play();
}
Because keyboard produces KeyboardEvent.KEY_DOWN event repeatedly as long as key is pressed, while MouseEvent.CLICK as well as MouseEvent.MOUSE_DOWN are dispatched only once per user action.
With mouse you need to change the logic.
// Subscribe both buttons.
ButtonRight.addEventListener(MouseEvent.MOUSE_DOWN, onButton);
ButtonLeft.addEventListener(MouseEvent.MOUSE_DOWN, onButton);
var currentSpeed:Number = 0;
var isPlaying:Boolean = false;
function onButton(e:MouseEvent):void
{
// Set up the directions and start the animation.
switch (e.currentTarget)
{
case ButtonLeft:
currentSpeed = -speed;
stik.stik2.play();
stik.scaleX = -1;
break;
case ButtonRight:
currentSpeed = speed;
stik.stik2.play();
stik.scaleX = 1;
break;
}
isPlaying = true;
// Call repeatedly to move character.
addEventListener(Event.ENTER_FRAME, onFrame);
// Hook the MOUSE_UP even even if it is outside the button or even stage.
stage.addEventListener(MouseEvent.MOUSE_UP, onUp);
}
function onFrame(e:Even):void
{
// Move character by the designated offset each frame.
stik.x += currentSpeed;
if (!isPlaying)
{
// Stop at last frame.
// if (stik.stik2.currentFrame == stik.stik2.totalFrames)
// Stop at frame 1.
if (stik.stik2.currentFrame == 1)
{
// Stop the animation.
stik.stik2.stop();
// Stop moving.
removeEventListener(Event.ENTER_FRAME, onFrame);
}
}
}
function onUp(e:MouseEvent):void
{
// Indicate to stop when the animation ends.
isPlaying = false;
// Unhook the MOUSE_UP event.
stage.removeEventListener(MouseEvent.MOUSE_UP, onUp);
}
I'm new to AS3 and have made a simple "asteroids" game with a game over screen and a resetButton that lets the user play again. When the user clicks on the reset button, the game over screen and the reset button are removed from the stage, and the game proper is added to the stage, along with eventListeners. One of these is a MouseEvent.CLICK listener added to the stage, which calls a fireBullet function. This function draws a bullet and adds it to the stage (other parts of the code then make the bullet move on the screen).
The issue that I am having is that when the user clicks on the reset button, the gameover screen is removed correctly, and the game proper (player, asteroids, eventListeners) are added to the stage correctly, but also at the same time a bullet fires even though the user has not clicked after clicking on the reset button.
My gameOver() function is like this:
stage.removeChild() all objects
stage.removeEventListener() all listeners
null out all objects
draw and add to the stage the game over text and resetButton
addEventListener(MouseEvent.CLICK, onReset) to the resetButton
Then, the onReset() function looks like this:
stage.removeChild() the gameover text and the resetButton
call gameStart();
The gameStart() function looks like this:
initialize variables
draw and add player and asteroids on the screen
add eventListeners including MouseEvent.Click, fireBullet
I've added traces at each function to see what's going on, and this is the flow:
added fireBullet listener //this is gameStart() function being called from Main() and adding everything to the stage the first time
fired bullet //shooting at the asteroids
fired bullet
fired bullet
fireBullet listener should have been removed //this is gameOver() being called that removes everything from the stage and adds the resetButton
clicked on reset
added fireBullet listener //gameStart() being called again from onReset() function
fired bullet //I did not click a second time after clicking on reset
I've read somewhere that events are dispatched all the time regardless if any listeners are actually listening for them, so my suspicion is that my MouseEvent.CLICK listener is picking up the mouse button click from the time when the reset button is clicked, even though this listener is added to the stage afterwards.
I don't have enough experience with AS3 or programming to figure out if this is really the case and what can I do to make sure that the MouseEvent.CLICK listener does not respond to any clicks that happened before it was added to the stage, so any help with this would be greatly appreciated.

EDIT
I was assuming I had a logic problem or didn't know something about AS3 and flash, so I just used pseudo code above. Below is a link to the full .as file including the generated .swf
And below that are the relevant functions in full

private function gameOver():void this is called from an onFrame(called every frame) function that I am not including (it's too big and not exactly relevant). it's called when all asteroids are removed.

trace("fireBullet listener should have been removed");
}

//remove gameover objects and null them

startGame();

What's happening is that MouseEvent.CLICK is a bubbling event. In Flash, events have three phases: the "capture phase", the "at target" phase, and "bubbling phase". You can read about it in this Adobe article.
Your reset button's click event handler happens in the "at target" phase. If you trace out the event's phase in the reset button click handler, it will show that event.phase is 2. Per the docs, 1 = "capture phase", 2 = "at target", 3 = "bubbling phase".
After the reset button click handler does its work, the event then bubbles back up through the display list. Since the stage is at the top of the display list, the click event "bubbles up" to the stage. And by that time, you've started the game again and added the stage's click event handler. So the stage's click handler is also triggered.
You can confirm this by tracing out the value of event.phase in your bulletFired() method:
private function fireBullet(e:MouseEvent):void
{
// most of this time it will trace out 2 for the phase
// except when you click on an asteroid when firing or
// click the reset button
trace("fired bullet, event phase: " + e.eventPhase);
bullet = drawBullet();
bullet.y = ship.y;
bullet.x = ship.x + (ship.width / 2);
bulletArray.push(bullet);
stage.addChild(bullet);
}
To fix the problem, you can stop the event from bubbling in your onReset() method:
private function onReset(e:MouseEvent):void
{
// prevent this event from bubbling
e.stopPropagation();
trace("clicked on reset");
//remove gameover objects and null them
resetButton.removeEventListener(MouseEvent.CLICK, onReset);
stage.removeChild(gameOverTxtField);
stage.removeChild(resetButton);
resetButton = null;
gameOverTxtField = null;
//restart the game
startGame();
}
It sounds to me like the previous iteration of your game has not had the MOUSE.CLICK event listener removed. Even if the game is removed, the MOUSE.CLICK event will continue triggering whatever handler you added to it, eg; addEventListener(MOUSE.ClICK, ). When the game is removed you also need to removeEventListener(MOUSE.CLICK, ).
how to disable keyboard keys in Action Script?
I'm creating Flash "memory" game, Idea to discover 2 equal cards. When 2nd card is discovered it is shown for 750 milliseconds, in that time player can't do any actions.
When I use this mouseChildren = false; player can't click with mouse for this time, but he can use keyboard arrows/enter/space/tab buttons... I need to disable It for this time.
Here is part of my code:
{
trace("Wrong");
_message = "Wrong";
message_txt.text = _message;
_secondCard = event.currentTarget;
var timer:Timer = new Timer(750, 1);
timer.addEventListener(TimerEvent.TIMER_COMPLETE, flipBack);
timer.start();
stage.addEventListener(KeyboardEvent.KEY_DOWN, blindKeyboard);//added here
stage.addEventListener(KeyboardEvent.KEY_UP, blindKeyboard);//added here
mouseChildren = false;
}
}
function blindKeyboard(e:KeyboardEvent):void{ //added here function
e.preventDefault();
e.stopPropagation();
}
protected function flipBack(event:TimerEvent):void
{
_firstCard.gotoAndPlay("flipBack");
_secondCard.gotoAndPlay("flipBack");
_firstCard.addEventListener(MouseEvent.CLICK, checkCards);
_secondCard.addEventListener(MouseEvent.CLICK, checkCards);
_firstCard = _secondCard = undefined;
mouseChildren = true;
}
You could just have functions for adding/removing listeners :
function addListeners():void
{
// loop through and add the listeners for the cards
// add keyboard listeners
}
function removeListeners():void
{
// loop through and remove listeners from the cards
// remove keyboard listeners
}
Before you set the timer, you remove your listeners :
removeListeners();
Then in your flipback timer handler you just call the addListeners :
addListeners();
Try
stage.addEventListener(KeyboardEvent.KEY_DOWN, blindKeyboard);
stage.addEventListener(KeyboardEvent.KEY_UP, blindKeyboard);
function blindKeyboard(e:KeyboardEvent):void{
e.preventDefault();
e.stopPropagation();
}
Okay, so I am a very amateur AS3 programmer. I have a timer setup, and after 45 seconds it should move to scene 6, however if it calls hitTestObject, it should stop and reload from 0 when the scene reloads. EDIT: I know this code is probably really bad coding, I'm also taking tips on how to fix this code up. Here's my code:
var myTimer:Timer = new Timer(1000, 1); // 1 second
myTimer.addEventListener(TimerEvent.TIMER, onEnterFrame);
myTimer.start();
{MAIN FUNCTION}
function onEnterFrame(e:Event):void {
var startTime:int=getTimer();
var currentTime:int=getTimer();
trace(currentTime);
if (currentTime>45000){
gotoAndStop(1, "Scene 6");
}
}
My issue, is that the timer keeps running when it hits test object and so when scene 3 is reloaded, the timer just keeps going. Therefore you only have to play for a total of 45 seconds, no matter how many times you die. It should be that once you die the timer reloads when you reload scene 3. Any ideas on what I can do?
Hope this helps:
var myTimer:Timer;
function resetTimer():void
{
// check if timer already initialize
if(myTimer != null)
{
// just reset
myTimer.stop();
myTimer.reset();
}
else
{
// initialize timer and set a 45 sec delay;
myTimer = new Timer(45*1000,1);
myTimer.addEventListener(TimerEvent.TIMER, handleTimerTick);
}
myTimer.start();
}
function handleTimerTick(event:TimerEvent):void
{
// stop and null timer;
myTimer.stop();
myTimer.removeEventListener(TimerEvent.TIMER, handleTimerTick);
myTimer = null;
// goto my 6th scene
gotoAndStop(1, "Scene 6");
}
// whenever a hit test is performed and a timer reset is needed just call
resetTimer();
