ActionScript 3.0 :: Calling Function With Event Listener Attached To Button
Jul 26, 2011
I 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?
I just started a course that does a little flash. To teach us they have us build a brick breaker game. I have come to a part were I have to remove all the Listener that were created for the game. Each level is a movie clip and when the level is over the level instance is removed from the child. From what I understand when the level is removed the Event.REMOVED_FROM_STAGE becomes true and the function attached should be called however it is not. Here is the code of the function that sets the listener and the function to be called:
Basically what I want to do is call a function attached to an event listener, without the event actually happening - for example:I have a function that is attached to Event.RESIZE.I would like to call that function from time to time, but this function of course requires an Event argument, so attempting to just call the function throws an error that it expects 1 argument and got none.
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.
I have an eventListener listening for mouse events, which will obviously call a function.The function being called is expecting a mouse event as a parameter (obviously).Question is, can I call the same function outwith the eventListener i.e. calling it without a mouse event?
I created a movie clip (mcPopup), deleted it from the stage, and set it to export for ActionScript. I then set up the movie to attatch the clip to the stage and then load a JPEG image into it. Now, I need to be able to let the viewer dismiss the popup, but I cannot figure out how to add an event listener to the movie clip. I tried several different ways, but the popup doesn't seem to be clickable and doesn't respond to clicks (perhaps the image is in the way?) Here is what I have for the code for the thumbnail the visitor clicks to open the popup:
on (release) { _root.attachMovie("mcPopup", "popup_mc", _root.getNextHighestDepth());
var timer:Timer = new Timer(milliseconds, repititions); timer.addEventListener(TimerEvent.TIMER, callback); timer.start();
and if a user click I want to call the callback early. Is there was a way to either force the timer to finish immediately, or stop it and send the TimerEvent.Timer on my own?
I'm looking for something simple like the tween classes fforward().
I am having problems with a flash project I am working on (flash cs5.5, as3).I have a movie clip with some animation in it, and when it reaches a certain point, I want it to call out a function that is on the first key frame on the stage (as in on the main timeline and not in a movie clip...).This is what I have so far in side that movie clip:
I'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.
I am working on a game for my university project and I have run into a bit of trouble. I have the following code here:
function launchBall() { this.stage.addEventListener(KeyboardEvent.KEY_DOWN ,launchBallHandler); function launchBallHandler(e:KeyboardEvent):void { if (e.keyCode==32) {
[Code].....
Its set up so that when a ball goes off screen, it resets to a coordinate and launchBall is called.
LaunchBall then adds the event listener to see when the Space key is pressed and that starts the ball moving again. The problem I have now is I cant seem to get rid of that eventListener. I have tried removeEventListener and that doesn't seem to work. I have tried:
if (ball.xVel>0 && ball.yVel>0) { removeEventListener(KeyboardEvent.KEY_DOWN,launchB allHandler);
just below that code and that doesn't work either. It's not spitting any errors out at me but I am completely stumped.
I have a method which registers an event listener to each of the MovieClips in an array I have. The method is inside a class, and so is the listener function. The problem is, I'm getting an error that's says "Access of undefined property handleNavToggle", even though is declared.
Does anyone know how to call a function setup to accept an event argument without triggering it through the event?
Example... I have a button with a CLICK event. When you click on the button, the associated function is executed. Now say I want to call that function from within another function. Is there a way to "send" the event information manually?
Right now I have the CLICK function simply call another function that would then be available to be called from any other location. Below is a code example of what I am trying to accomplish.
Code: Select allbutton.addEventListener(MouseEvent.CLICK, doButtonClick); function doButtonClick(e:MouseEvent):void {
How do i pass a variable to a function from an event listener which is inside a function Below is a function that is called when after loading some variables
function dataOK(mydataevent:Event):void{ var j:int = 0; do { trace(j);
[Code]....
This is a simplified version of the original code. The above function generates an error because j is undefined in the function. I am wanting to get the variable j when the button is pressed.
How do I pass the variable j to the Button_Click function?
I'd like a movie clip called "following_cursor_mc" to follow the cursor, regardless of which of several different frames the playhead may be on. I've reproduced the code below on each frame in which I would like the cursor to be followed by "following_cursor_mc" but these errors are thrown for each of the frames:
I'm trying to return XML from an event complete back to the main function, but can't figure out how to do it.Here's the functions I'm calling:Main File:
public var mySendAndLoad:SendAndLoad = new SendAndLoad(); mySendAndLoad.sendData(url,variables) The mySendAndLoad class:
I am trying to create an event listener to check that a function has completed before the next action is run. In simple terms I have a module that is opened and closed via two functions... module_open() and module_close().Each function has tween elements that must complete before the next element is processed... i.e the next function, etc.This is the code I have ( have attempted to create an event listener but I seem doing something wrong. I am not even sure that it is possible to create an event listener that checks for a function finishing before calling the next function.
Code: function onAbout(event:Event):void { module_close() module_close.addEventListener(Event.COMPLETE, onClose_Complete);
I cant because it runs off a VideoEvent, not a MouseEvent.The obvious work around is to copy and paste the function and rename this part, or alternativly just make a function such as:
Code: button.addEventListener(MouseEvent.CLICK,callMyVideoFunction); function callMyVideoFunction (event:MouseEvent) { myVideoFunction(null);[code].....
The keyBoard event listeners call on the rotate and unrotate functions and based on the key inputs(A and D) will implement either of the functions and rotate the image or return it to the original upright position. However, I haven't been able to get the function to work. When I press the A or D keys on the keyboard nothing happens. I even put trace() in one of the functions to see if the function will even be implemented but I don't get anything. I put in my Scripts below. Why are the functions not working? Do the eventlisteners fire or are there conflicts? I'm not getting any error messages.
I am trying to essentially pass a string as a function name into an event listener, but I am not sure how to approach this. Is there a way to convert a string into a function?
Here is some code I have for me to show you what I am doing.
package{ //some import statements public class changes extends MovieClip{
Since when using sql lite if you try and do a function at the same moment it throws an error, im just trying to make a function that will check if its executing, and if it is try again in 10 milliseconds, this exact function works fine if i dont have to pass any arguments to the function but im confused how I can pass the vars back into the function it'll be executing.[code]
