All my other instances I can access on my main movie from within my main movie except my button named play_game. Whenever I tried to trace or access it, it says its null. Do I have to do something special in order to access button instances?
View 5 RepliesI'm trying to create an Event Listener used with all buttons placed on the stage rather than a listener for each button object.Are coding examples of a class listener?
View 5 RepliesI'll keep this simple (I hope). There's a button with an event listener on a frame of the main timeline. You click the button to go to the next frame and a movie clip plays. The instance of that button doesn't exist on that next frame. Does the event listener for the button automatically get removed when you go to that frame since the button doesn't exist there?
The movie clip is set up to send the main timeline back to the previous frame when it's finished and my event listener seems to vanish when I go back to that frame.
I'm creating a minesweeper game as my first flash project, but I'm already stuck on something technical. I have created a button named Button which contains a bitmap. I have a lot of instances of that button on stage, and they are put there by actionscript using a for-loop. Their instance names are button0, button1, button2, button3, etc.
This is the code for the eventlistener: It's in the first keyframe of the actions layer.
var buttonListener:Object=new Object();
buttonListener.click=function(evt:Object):Void{
trace("clicked");
} for (i=0; i<rows*cols; i++) {
eval("button"+i).addEventListener("click", buttonListener);
}
I also noticed that when I do this for one button that I created myself and put on the stage manually, this also doesn't work, but when I pick one of the predefined buttons, it works just fine.
isit possible to call two functions from one button event listener?
or is it even possible to write two seperate listeners for one button that listen for the same thing an example is shown in the code;
also, i have string variable, that i want to use to call a certain funtion depending on the variable, for example the vairables name is phase_no can i do next_btn.addEventListener(MouseEvent.CLICK,nextPhase,beginSubmit+phas e_no)??
Is there any way in AS2 to add an event listener NOT to a particular button instance in the stage, but to any symbol in the stage which is a Button?[code]...

I would like to have a movie to play when the mouse is over a button instead of when it is clicked. My script is now:
btn1.addEventListener(MouseEvent.CLICK, buttonClick);
Here is my full code
import fl.controls.*;
var test:MovieClip = new MovieClip();
var btn:Button;
[code]....
Result:
You clicked 8
You clicked 8
You clicked 8...
Is there anyway, such that, I can use for loop to create different name button, and add it to an event listener?
make the nearest button to the clicked text input default. For this purpose, I wrote the below code.
why is my buttonSwitcher function following behind the MouseEvent.CLICK?

I have a set of buttons on, and what i would like to do is change the value of a variable, depending which button you are over.i know i could do this by writing an event listener and a function for each button, but this is too time consuming.I'm sure in the old days it would have been as simple as if btnwhatever.mousedown = true then.... but now i have no idea.
View 1 RepliesI would like to know if it is possible to pass a clip event on to both the function that has a listener, and to the button that is being pressed. I am finding the listener takes it and thus the button doesn't see it.I found a walk around, however, I'd like to know if it is possible say for one clip event to be seen by both objects?For example, with the mouse over a button the listener function detects the event and carries itself out, however, the button misses the event now.
View 2 RepliesWhenever I remove an event listener to a button then that button no longer works. Does it cause memory leaks to not remove these listeners.....come to think of it I have about 30 eventListeners that I cannot remove otherwise the application ceases to function correctly. Is my application a memory black hole? How should i proceed with garbage collection?
View 3 RepliesI have a situation where I'm calling a function with an event listener attached to a button, which in turn calls a function, which does a number things including calling a second function which resides in a child swf.
Just as an example:
Code:
myBtn.addEventListener(MouseEvent.CLICK, firstFunction);
function firstFunction(e:MouseEvent):void{
//I call another function in here (among other things)
externalSwf.stopTimer();
}
"StopTimer" resides in an external swf which for our purposes is called externalSwf and it resets a running timer.
Code:
function stopTimer():void{
myTimer.reset();
}
I'm getting argument mismatch errors, which often have to do with the Event Objects not matching. The event object for firstFunction is a mouse event triggered by a click so I put in e:MouseEvent...what I don't clearly understand is, what type of object event is dispatched when I call the function stopTimer from inside the function firstFunction?
On the main timeline, I have placed a movieclip (movieclipone) which contains some content. On frame 85 of movieclipone, there is a new keyframe which contains a movieclip that hasn't previously appeared in the movieclipone timeline, (moviecliptwo) which contains four buttons (btnone, et cetera).Is there a way to have code in the main timeline that attaches listeners to the buttons inside moviecliptwo, which, when pressed, trigger a function that increases a counter and tells movieclipone to go to the next frame? This is the code I am using right now:
stop();
movieclipone.addEventListener(Event.ENTER_FRAME, onEnter);function onEnter(e:Event):void [code]........
When I debug the movie, I get this error at frame 85:TypeError: Error #1009: Cannot access a property or method of a null object reference.
I have a tab navigator defined in MXML, with two tabs.In each tab, I have some buttons. I have used ActionScript to add event listeners to all the buttons, and they work for the buttons that are visible (and in the currently "active" tab) when I load my Flex 4.5 AIR application.However, I get an AIR error for the event listeners attached to the buttons in the second tab.Here's the crucial part of the error:TypeError: Error #1009: Cannot access a property or method of a null object reference.

I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
View 3 RepliesI'm having issue where the titleBar event listener is override the buttons (i.e. close button) event listener. In my codes, i have a button called close button added to the titleBar. when i try to do the mouse over/out event listener for titleBar and close button, only the titleBar would react. It seems that the event listeners for titleBar are overriding the button event listeners. (Basically i want to change the mouse cursor icon when targeting the title bar and then different mouse cursor icon when targeting the close button)
View 5 Repliesif I have an event listerner (mouse, keyboard, enterframe,....event) that is being triggered, and when it finishes its event, something that is able to detect the finished event listener and fire out another sets of event.
It works more like MOTION_FINISH in TweenEvent, but it is only available for TweenEvent only, what if I want to detect a mousclick, keyboard, enterframe or even touch event?
My stage has about 25 buttons on it. Each button when pressed to tweens the background to some random x/y coordinates and then loads an external swf file.This is all working, but the timing is off. How can I wait for the initial background tween to end before I make the loader call to the .swf file.Currently each button's behavior is called on the MouseEvent.CLICK event which calls a function that knows its unique filename.swf. I know you can add the MOTION_FINISH even to the tween event but then I would have to call a new function and lose track of the button that initially called it.
View 3 RepliesI'm moving on to my next massive programming project and I'm trying to decide whether I should code it in as 2.0 or 3.0. I came across the new click event model in 3.0. Right now it's looking like a pain in the butt to me. So now I have to make a function and add it as an event listener? what the hell? What's the benefit? I understand stuff like this makes AS a more complete language but it's kinda annoying.
View 1 RepliesThis is a very basic question but I can't seem to find an answer. I have a mouse over event and have created the buttons with the mouse overs which is working great. I created the actionscript to go to a specific web page when a user clicks the button. Now, I need to add a label to the mouse over so when someone mouse's over any area of the button, it will show them a particular name for the button.
I am sure that this can be done using actionscript in a mouse event roll over command but I can't figure out what I need to show the text. Here is where I am:

how can i access event.target outside event listener method.say for example
my_mc.addEventListener(MouseEvent.CLICK, onC);
function onC(e:MouseEvent):void
{
var m:MovieClip = e.target as MovieClip;
}
trace(m.totalframes);/// not working
now what if i want to get totalframe property of m instance, in short for every movieClip clicked.
I am doing this inside a module containing viewstacks and their childs.Calling onInit() on creationComplete of module.When I am inside one of the childs of a viewstack of this module and press Enter, it doesnt not invoke the listener function at all (bp inside this does not get hit).
private function onInit():void{
this.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
}[code]..........
This might be more of a subjective question, but is it generally best practice to have one dedicated method per event-types that you add an event-listener?
Such as:
myButton.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
myButton.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
//Somewhere else in the code...
[Code].....
And if you had a MouseEvent.MOUSE_UP, MouseEvent.MOUSE_DOWN and other relevant MouseEvents event-listeners to watch for, you could even set a switch statement to handle all the various MouseEvent types.
I have these buttons in a movie clip and I would like to have only one event listener for the parent, using event.target to point to the children. I have also tried event.currentTarget, and it didn't work.here is the code that works:
test01.abtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.bbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.cbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);[code]....
It is only targeting the movie clip, not the buttons inside the movie clip.
