fileReference.addEventListener(Event.COMPLETE, uploadCompleteHandler); private function uploadCompleteHandler(event:Event):void {}
Above is one way to add an event listener in Actionscript. By default the callback function needs to have an argument with name event and type Event. Is there a way to declare this function without any arguments :
private function uploadCompleteHandler():void {}
Edit : It's possible to add an event handler without any arguments in mxml. So one student wanted to know, why isn't it possible to do the same in actionscript?
I am trying to create a drag and drop activity, and I would like to use an array for easy reusability.I'm new to as3 so I've been adjusting my old as2 code. I am using a component for each of my drags and most of it is working well.My problem is with the event handlers. I use the array to populate all of my 'drags' with the information added in their parameters and this works, but when I create my event listeners it seems to only want to move the last item in the array.My drag components are called drag1, drag2, and drag3.[code]
I'm trying to make a flash version of those refrigerator magnet poetry kits. As such I have about 150-180 little MCs each with a different word. They are all named sequentially, so theoretically I could just make some array counter or something to stick the handlers on right?
I have some MovieClip class that has eventListener, added from inside the constructor of the class (it's MouseEvent.MOUSE_DOWN). Now, I want to add the same listener externally, from parent class, for other purposes. Will these two interfere with each other or it's okay?
I want to make a little game. What I need is to add event listeners to all of Tank objects inside the Battlefield instance. I just can seem to figure out how.
I have made an event listener:text0_mc.addEventListener(MouseEvent.CLICK, showMe);showMe is a function, but I need it to call more than 1 function at once i.e. -ext0_mc.addEventListener(MouseEvent.CLICK, showMe1, showMe2, showMe3, showMe4, showMe5, showMe6, showMe7);Each function contains an if statment as below.
function showMe1(event:MouseEvent):void { if (shuffledArray[1]==orderArray[1]){
What I am trying to do is, if a user presses keyboard (key 1), picture 1 should FadeIn and if a user presses keyboard (key 2) picture one should FadeOut and picture 2 FadeIn and vice-versa. With the code mentioned below it works fine sometimes if I am not pressing any other key while it is performing one action but sometimes it behaves weird also. What I want AS3 to do is not to take any action or in other words it should not listen to keyboard until it finishes the opening or closing animation of a picture or any other object assigned to the key.
stage.addEventListener (KeyboardEvent.KEY_DOWN, KeyDownHandler); /**///keyboard keycode for 1 & 2var key1:uint = 49; var key2:uint = 50; var BG1:Image1 = new Image1(); var BG2:Image2 = new Image2(); [Code] .....
I've had this glitch for a long time, and I've tried several ways to get rid of it, and now that I just recoded everything to see if it was something I did, it's back again! basically, whenever I press space (regardless of whether or not I am listening for a space press [or any key press]), the last function fired by an event listener will run itself again, with the exact same arguments supplied to it in the first time.
For example, if I make a simple button to trace("text"); and take you to another frame. Once you get to that frame you can press Space and it'll trace "text" again! I really have no idea what's causing this, and it doesn't seem to be happening to me in new files. and there's too much code to show you, but I just want to know if anyone has heard of this before or if they have any theories to what's going on.
I'm currently working on a nav bar but I've run into a questionable situation. There are several links in the menu, and for each i'd like a mouse event on over and on out. Do I have to specify both of these events for each link, or is there an easier way to do it that I don't know about? Can you apply event listeners to multiple objects/functions?
I have some functions that when applied directly to buttons work as planned, but when I create a function from them to apply to the array, they fail to execute properly. This function is meant to set all 56 buttons to alpha 0, and as unselected. What happens is the buttons flash onscreen at 100% before setting to alpha 0. They do behave as if unselected, but don't know if that's due to the code.
This function should fade the button up on rollover. But on rollover the button only increase by 10% then stops. Each subsequent rollover increases it another 10%. Code: for (_root.i = 0;i<56;i++){ _root["btn"+_root.i].onRollOver = function() { this._alpha<100 ? this._alpha += 10 : this.onEnterFrame = ""; }}
This function should fade the button out on rollout. Since the rollover increases them only by 10% increments (above), the result is the buttons just bounce back and forth between alpha 20 and 30. Code: for (_root.i = 0;i<56;i++){ _root["btn"+_root.i].onRollOut = function() { (this._alpha>20 && this.bSelected==false) ? this._alpha -= 10 : this.onEnterFrame = ""; }}
Last one: This function should set several behaviors on release. Right now none of them appear to work. Code: for (_root.i = 0;i<56;i++){ _root["btn"+_root.i].onRelease = function() { this.bSelected = true; this.enabled = false; pastBtn.enabled = true; pastBtn._alpha = 20; pastBtn.bSelected = false; pastBtn = this; }}
I have 2 functions. Each one is being called by a different event listener. Both event listeners work because I am able to trace strings in both of them.. my problem is that i am trying to create a variable that is local to both functions. The first function "working" adds a number to the variable and when the second event listener triggers function "notworking" which retrieves this same variable called "counting" both functions are called automatically by event listeners.. how do I do this? i am stomped!
I've managed to create a button which on MOUSE_DOWN scales its parent object- it works just like windows in your OS, where you grab the corner and can change the scale of the window.
Here's how I've done it, (minus the MOUSE_DOWN listener)
Code: function scaleDragHandler(event:Event):void { var mcWidth:Number = event.target.parent.width; var mcHeight:Number = event.target.parent.height;
[Code].....
However, it throws the error, "Access to undefined property 'scaleMC'" on the removeEventListener line. My thought was to put another listener for mouse up inside the first, but that sounds wrong
I'm trying to do something that I'm not sure if it's possible. I have to add or remove multiple listeners that will trigger the same three methods (onComplete, onError and showProgress). I was trying to do something like this:
[Code]...
Is there anyway to solve this? It seems that after passing through the addListeners method, the loader instance gets lost.
ive made a flash website containing 5 pages all accessed via flash buttonson one of the page ive tried loading a external swf file and then added event listeners to each of the buttons so when a new page is selected the swf file doesnt continue to play in the background on the other pagesthis works, however when i then try to change page again this error is displayed:ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.at flash.display:isplayObjectContainer/removeChild()atValleyViewingWebsite_fla::MainTimeline/btnClick()below is the code im using:
var Xpos:Number = 110; var Ypos:Number = 170; var swf:MovieClip;
I've created this code to loop through an array of image names and load them to the stage. Currently I'm just stepping them down 175 pixels each, which eventually I'll want to offset by the height of each of them (but I'm having an issue with that too lol ). Anyway...my question is, I've seen code to add event listners to each movie clip dynamically, but that code was working on static movie clips. I want to add the listners to my dynamic images and I'm not sure what that should look like.
[Code]....
I know this isn't correct, specifically in the captureAllClicks function...but I'm not sure how else to reference the current item since it was dynamically generated.
I'm adding and removing stage event listeners I am relatively new to AS 3 and have been building a liquid layout site unfortunately I do not have a strong grasp of classes and have been doing all of my scripting on the main timeline with encapsulated script within MC's.
basically I am calling on the same functions over and over and those are mostly resize functions which I have added StageEventListeners on the appropriate frames to listen for resize events on that stage now as of now I have literally dozens of these scattered about the site. when testing my site things are running fairly smoothly however I keep getting error messages in my output window that go a little something like this.
I have 22 buttons (each named buttoni where i is a number between 0-21...e.g. button0, button1, button2) that I've created and artfully arranged on the stage in my .fla file. The document class for the .fla file is People.as, and in People I'd like to give each button a rollover and click event listener, but I can't figure out how to refer to them using a loop.
Here's my code, which obviously doesn't work:
ActionScript Code: private function initButtons() : void { for (var i:int = 0; i<numSquares; i++) { var thisButton : String = "button" + i;
What I want to do is be able to click a button that adds an Item to the stage and then you are able to drag the item around on the stage. I know how to do these things separately as in if the item is already on the stage I know how to add the code to drag it and I know how to create a button that brings a library item on the stage. How would I combine the two?
I have done this same thing in ActionScript 3, but am not familiar with ActionScript 2, which I am forced to use for this project. I am loading products into a SWF via XML and attempting to add a click event to each dynamically-created movieclip. Simply tracing the text from a node in XML will do for now. I'd like to assign a property called "desc" or "description" to each movieclip and have it trace that property's value when clicked. Here is the relevant portion of my code as it stands:
I'd like to add event listeners to movieclips (already on the stage), whose names are called from an array one by one, into a for loop.
Code: // there are 4 movielcips on the stage with name a1 - a4. // create array var Bro:Array = ["a1","a2","a3","a4"]; // for loop for ( var i:Number = 0; i < 4; i++) { // Add event listener to array values to buttons. Bro[i].addEventListener(MouseEvent.ROLL_OVER, roll, false, 0, true); //execute this function on rollover function roll() { trace("why wont my arrays work in for loops"); }}
What is the best way to make a menu with items that can be bought ( a.k.a shop ), bought items are invisible and there are about 20 items or so. What's the better approach than adding mouse event listeners to all 20 items?
I've created a drop down list and populated it with dynamic buttons. (I made a DropDown_btn class with a dynamic text field in it and then filled the button text from an xml file). On rollover I tint the button blue and then set the tint back to black on rollout. When you click on the button I'd like it to stay blue until a different button is clicked.
...and then I need to addEventListeners back to any button that doesn't have them and set that button back to black. I could do this by looping through an array of the buttons but I can't figure out how to access them as objects.
I also gave them each a property of "buttonValue" when I loaded them so I can access event.currentTarget.buttonValue (which in this case is a number from 1-5) but once again I can't figure out how I might leverage this information.
I would imagine it's a simple enough bit of additional code, but I'm no programmer, and trawling the Web has proved fruitless to date...ithin Flash CS5 and using AS 3, I'm attempting to create a series of drag-and-drop interactions for a learning exercise where items must be dragged into the correct box with positive and negative feedback being generated as a result of where the learner drops the item. All I need is the code to link the drag and drop code snippet (which I have working) to a specific object/location on the stage (which I cannot find nor figure out for the life of me)
I am using CS3 set to AS3. On frame one I have 120 buttons ( yes, one hundred twenty buttons), unfortunately I have tried to reduce this but to no avail. Anyway, I know I can put these into an array to take away some of the coding. but my question is can I also use a integer?
My button are named Btn1 - Btn120. I would want to use the array and integer for simple things such as event listeners for roll over, click, roll out, and a couple of basic if statements. All of the buttons are movie clips.For some other more detailed functions I know I could still call the button name ( at least I think I should still be able to), but wanted to make sure.
