I have an phone app that displays certain text info, on stage, based on the day (e.g. Sunday, Monday...). When the day changes, Sunday to Monday, it should display Monday's info but it doesn't update when I test in the phone. I think this is because the phone holds the memory of where the user was. So, I need to make the app reload somehow, so it gets the correct info matching the day. I was thinking to do this with a user button (see below) but have not been successful with the reload. Any ideas please? Thank you in advance.
myButton.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
function fl_MouseClickHandler(event:MouseEvent):void {
if (myText1.stage) {
removeChild(myText1);
}
else {
addChild(myText1);
}
}
That piece of code just removes the text from it's parent or adds it back.
What you probably want to do is to update the text property of it using the current day.
Something like :
myButton.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
function fl_MouseClickHandler(event:MouseEvent):void {
var days:Object = {
0:"Sunday",1:"Monday",2:"Tuesday",
3:"Wednesday",4:"Thursday",5:"Friday",6:"Saturday"};
myText1.text = days[new Date().getDay()];
}
I was able to put the function that gets the information, within a button function, which updates when the user clicks.

When I navigate to a page using this event:
this.events.subscribe('liveTrackingEvent', (time, unit) => {
console.log("event triggered");
this.searchForm.controls['unitID'].setValue(this.unitSelected.unit.name);
this.GetLiveData();
});
everything gets called, also the function GetLiveData(). (I didn't post this function's code because it's irelevant)
However when I look at the page, not 1 element is updating. So this line:
this.searchForm.controls['unitID'].setValue(this.unitSelected.unit.name);
doesn't update the searchform control, however when I call this line of code from the page itself without the event getting triggered on another page, it works smoothly and updates the searchform control.
(It's like I'm on a separate thread for some reason), I'm putting this between brackets because it's just a thought.
So my question is: How do I force this page to update itself also when the event is triggered?
Thanks in advance and if you guys need more code just ask, but this is the most relevant code because everything is working just not when it gets called inside the event.
By using page life cycle events instead of custom events from the ionic framework I managed to make this work and even have a cleaner code.
example:
1st page:
GoToLiveTracking(unitID){
this.navCtrl.push(MapPage, {redirected: true, unitID: unitID});
}
2nd page:
ionViewDidEnter(){
if(this.navParams.get('redirected')){
let unit_id = this.navParams.get('unitID');
this.unitSelected = this.completeService.GetUnitByID(unit_id);
this.searchForm.controls['unitID'].setValue(this.unitSelected.unit.name);
this.GetLiveData();
}
}
I could think of only 1 reason for this behavior. You are updating your form outside of Angular Zone. That’s why the changes are not getting detected.
To fix the issue, wrapped the call of last 2 lines of event into “this.ngZone.run(() => { ... })”.
e.g
this.events.subscribe('liveTrackingEvent', (time, unit) => {
console.log("event triggered");
this.ngZone.run(()=>{
this.searchForm.controls['unitID'].setValue(this.unitSelected.unit.name);
this.GetLiveData();
});
});
Let me set the stage because it's too much code to post everything:
I have a Main.as that is setting up my SoundController.as so I can trigger sounds from any other class (SoundController.as has all the functions needed to call all my sounds as needed)
I have a ControlPanel.as that can access these sounds by using docRef.soundControl.laserFire or whatever other function name I want, and in this case the laserFire sound would trigger once.
So here is my question. I want to let this laser sound effect finish playing before you can fire another laser. So in SoundController.as I've set up the following pieces of code:
private var _laserPlaying:Boolean = false;
internal function laserFire():void {
_sfxChannel = _laser.play(25);
_laserPlaying=true;
_sfxChannel.addEventListener(Event.SOUND_COMPLETE, laserFinished);
}
internal function laserFinished(event:Event):void {
_sfxChannel.removeEventListener(Event.SOUND_COMPLETE, laserFinished);
_laserPlaying=false;
}
public function get laserPlaying():Boolean {
return _laserPlaying;
}
public function set laserPlaying(value:Boolean):void {
_laserPlaying = value;
}
Now in my ControlPanel class in the enterFrameHandler function I want to do an
if (docRef.soundControl.laserPlaying()==false)
or something to that effect so I can check when the sound is done and allow the player to once again press the trigger to fire the laser. So far any variant I've tried on this either gives me an error (in this case 1195; Attempted access of inaccessible method laserPlaying through a reference with static type SoundController) or it actually compiles but after firing the first laser shot it never allows the trigger to be pressed again. So I'm obviously doing something wrong and am hoping someone can help.
Let me just state that the laser sound is playing just fine that first time, so don't worry about all the code I'm not bothering to show to make that portion of the code work. However, if more info is needed to understand how I'm making anything work just let me know. And Thanks in advance!
If your soundController AND ControlPanel are instantiated in Main:
handle the firing event, in ControlPanel, like this:
if(MovieClip(parent).soundController.soundChannel.position==0)
{
MovieClip(parent).soundController.laserfire();
}else{do nothing;}
Of course use proper instance names.
If this doesn't work you'll have to make your code a little easier to understand.
Sorry for wasting everyone's time. I ended up figuring out what I needed to do to make this work. This probably won't be of much use to anyone else since my setup was probably unique to my layout and not something that anyone else will try, but here is what I did anyway.
In my ControlPanel.as I added the following code:
private var _soundController:SoundController;
And then I have a function that waits for the ControlPanel to be added to the stage and once that occurs I fired:
_soundController = new SoundController(docRef);
Now by adding those I was able to simply call:
if(!_soundController.laserPlaying) { do stuff; }
It now seems to wait for laserPlaying to be false and then moves on as intended.
Im trying to set my LWJGL Mouse to grabbed and not grabbed when i push the left mouse button.
However this has proven to become a tricky matter since the LWJGL mouse for some matter executes the command multiple times randomly. For an example:
if (Mouse.isButtonDown(0)){
Mouse.setGrabbed( !Mouse.isGrabbed() );
System.out.println("Pushed");
}
if(Mouse.isGrabbed()){
camera.processMouse(1, 80, -80);
If i run this code it will print "Pushed" several times randomly per push. As you can imagine that becomes a problem when i try to set my Mouse to grabbed true or false from each click. the times i have tried this code it has printed "Pushed" 4 - 7 times per click
is there any way to make the Mouse only carry out the command once per click?
many thanks in advance to everyone who will take time to help me solve this problem.

An easy way is to check a boolean field which you flip on the first iteration of the block after the mouse is clicked or released to tell you if this is the first time since the click that the if block has been executed. Here's an example:
private boolean alreadyClicked;
void someMethod(){
if(Mouse.isButtonDown(0)){
if(!alreadyClicked){
alreadyClicked = true;
// do what you want to do when the mouse is clicked
}
}
else{
alreadyClicked = false;
}
}
Alternatively you could use the event buffer of the Mouse class to detect clicks like this:
while(Mouse.next()) {
if(Mouse.getEventButton() == 0) {
if(Mouse.getEventButtonState()) {
// clicked
}
else{
// released
}
}
}
this is actually a noobish question, but is there a possible way to save a certain state of a movieclip?, example i dynamically added a movieclip called big_mc, then inside big_mc contains three(3) smaller movie called child_mc1 and child_mc2 and a close_big to remove big_mc from the stage, when i click either of child_mc1 and child_mc2, the child_mc will disappear prior to which child_mc i clicked.
so the scenario is when I click child_mc1 which remove itself from the scene, then next I'll click the close_big movieclip to remove big_mc from the stage and will save it's own state, so then the next time i run the SWF file and dynamically add big_mc to stage, child_mc1 would be still missing and child_mc2 would still be displayed (EVEN IF I CLOSE THE SWF FILE, the state should be saved). please help..much is appreciated.
code in main time line:
var big_mc:mother_mc = new mother_mc;
add_big_btn.addEventListener(MouseEvent.CLICK, call_big);
function call_big(e:MouseEvent):void
{
addChild(big_mc);
}
the code inside big_mc:
child_mc1.addEventListener(MouseEvent.CLICK, remove_child1);
child_mc2.addEventListener(MouseEvent.CLICK, remove_child2);
close_big.addEventListener(MouseEvent.CLICK, bye);
function remove_child1(e:MouseEvent):void
{
removeChild(child_mc1);
}
function remove_child2(e:MouseEvent):void
{
removeChild(child_mc2);
}
function bye(e:MouseEvent):void
{
this.parent.removeChild(this);
}
You want to start with SharedObject, which as Adobe puts it, "is used to read and store limited amounts of data on a user's computer or on a server". To save the "state" of the MovieClip is more complicated.
What about it do you want to save? The x property? Perhaps the alpha? EVERYTHING? Each object is stored in a default state in your swf. Library items in the Flash IDE are technically miniature classes, as evidenced by the way we instantiate them. Assuming you create something called customButton, you could spawn thousands of them onscreen (or one) like this:
var foo:customButton = new customButton();
Like a hand-written class, a copy of the customButton is created with all the properties you defined on it before you compiled it. If you want to change those properties, you have to address each and every one you want different.
Looking at this broadly, let's assuming you want to save the position of your button every time you load the swf. Load with getLocal(), and save with flush().
var settings:Object = SharedObject.getLocal("foo");
function updateState(e:Event):void {
myButton.x = settings.x;
myButton.y = settings.y;
}
function saveState():void {
settings.x = myButton.x;
settings.y = myButton.y;
settings.flush();
}
It's not impossible; there's simply no push-button solution for it. If you wanted, you could write a function which iterates over all DisplayObjects, and loads/saves each relavent property from/into your SharedObject. Might be overkill, though.
I am relatively new to ActionScript (have started with it 2 months ago), and have a little doubt of 'procedure' or 'technique' related to passing information between objects.
I have made a class that Pops-up a window that contains a panel with a textbox and two buttons, one for accepting, other for cancelling. It should work as a prompt in which you enter some text, and then if you like the changes, you accept, else, you cancel and the text you entered is discarded.
The thing I'm not sure how to handle is how to receive the text, once the user presses 'Accept', from the class I want to receive it from.
So, the approach I took is a bit cumbersome: firstly, when launching the popup, I associate with it a function (called onResult() in the code) from the 'class that launches', which will be called after the user presses the 'Accept' or 'Cancel' buttons; secondly, to get the text that the user inserted in the box, I keep a reference to it public from my class.
Please have a look at the code here:
http://pastebin.com/Kmud8rBe
I've also programmed in Android before, and the approach there would be much cleanier, just putting the text result from the popup inside a bundle inside an intent, and receiving it from the launched class. Here, I have to pass functions and such, which I don't like at all (although it works!).
So, my question is, for you ActionScript gurus out there, how would you approach this?
Thanks and regards!

good that you created a class for your popup-functionality but why did you make all functions static? normal class with normal methods would be better ... and let the class extend from Sprite so that you can add the instance right to the stage.
package
{
import flash.display.Sprite;
public class Popup extends Sprite
{
public function Popup (label:String)
{
// add text and buttons ...
}
}
}
then you can just say:
var pop:Popup = new Popup("message");
addChild(pop);
and to get the data back after the popup is closed you would do sth like this:
private function onPressedAccept(event:MouseEvent):void
{
var text:String = _label.text;
// dispatch a custom event which saves the text as its data
dispatchEvent(new MyEvent(MyEvent.ACCEPT, text));
// close popup ...
parent.removeChild(this);
// or you would remove the popup in the ACCEPT eventlistener ...
}
listening for accept/cancel:
var pop:Popup = new Popup("message");
addChild(pop);
// add eventlistener
popup.addEventListener(MyEvent.ACCEPT, onAccept);
popup.addEventListener(MyEvent.CANCEL, onCancel);
private function onAccept(event:MyEvent):void
{
trace(event.data);
}
