AS3 :: Flash - Returning A Variable From An Event Listener Function?
Sep 28, 2011
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:
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 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.
I have a variable which needs to be updated upon user input. It works inside the function, the trace function returns the correct type, but for a reason it wont pass it on the variable on the main timeline.[code]
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].....
i'm trying to check if a movieclip has an event listener with a sepecific function bound to it. The hasEventListener function only accepts one parameter (the listener). What i would need would be an hasEventListener that accepts a second parameter, namely the function that is bound to it.
Code: if (!mc.hasEventListener(MouseEvent.ROLL_OVER) { mc.addEventListener(MouseEvent.ROLL_OVER, overHandler); }
but what i would need is:
Code: if (!mc.hasEventListener(MouseEvent.ROLL_OVER, overHandler) { mc.addEventListener(MouseEvent.ROLL_OVER, overHandler); }
because i bind more than one ROLL_OVER listeners to that mc.
ok so i've been stuck on this for a while...What i'm trying to do is create a function that updates a global variable (randomVar) that is itself a parameter in the function e.g
[Code]....
Basically, i thought randomVar and vari were the same so when vari was changed randomVar would too but that's not the case. So how do i make the parameter equal the new value(5). I want to repeat the function using different variables so putting randomVar = vari in the function is not possible.
I am working with code where the variable "k" is a counter. I stripped out the extraneous stuff from the code below - so essentially when the function onExamPlusClick is called, the counter "k" and the minutes of an activity in an array both increment (as well as other things not shown). I'd like to return "k" as well as "activity[0].minutes" to the main program. Since the function is a MouseEvent, I'm unable to change "void" to "number"... and not sure how to return (pass) those variables back to the ain program.
However, on a bright note its coming!!!! So far, everything is going well and I am now seeing the light with AS3I do have a question on returning a variable from a function that loads an external CSS. This particular function is located inside a LoadStyleSheet.as class along with another public function that sets text properties to fields when accessed. What I am looking for is accessing the stylesheet after its been loaded in another class. I know in AS2 I could use the Delegate method for something similar to this situation. Not sure what the next step is for AS3. Anyhow, function script is below.
ActionScript Code: public function loadStyleSheetItem(loadStyleSheet_str:String):void { var styleSheet_css = new StyleSheet;
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 trying to return an XML object, but having issues. The object is only created via an Event.complete function. I need to return the XML created from my loadXML function via my grabXMLfromFile function.
Code: function grabXMLFromFile(attrPathToXML:String):XML { var fileUrl:String = attrPathToXML; var myUrlRequest:URLRequest = new URLRequest(fileUrl);
I headed some problem which can't solve. It's simple. I'm making slideshow, and wanna pictures to be dynamically loaded. List of images is stored in list.xml - a valid xml file. Now, here is piece of the code:
var imgno :Number ; //the var which tells the number of images listed in list.xml var myXML:XML; var myLoader:URLLoader = new URLLoader();
[Code]....
So, the triggered function processXML cannot change value of any variable which stands out of her. Is there a way to export (in this case) information about amount of images listed in list.xml to some of the variables that I can use later (for example imgno).
I have 3-4 swf those i want to load one after another like a slideshow.What i want to do is get the total frames of loaded swf and want to pass that value to Timer object's delay parameter. i have converted total frames to milliseconds so i can use it in timer constructor. But i am not getting the value of that variable outside of my Event.COMPLETE listener method. Here is my code what i have done
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 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:
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 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.
