ActionScript 3 :: Navigation Menu - Adding Listeners To MovieClip
Apr 4, 2012
I'm new to Actionscript 3, and what I'm trying to do is build a navigation menu. What I did is I made a movieclip, added two listeners to it, MOUSE_OVER, and MOUSE_OUT, the MOUSE_OVER tells the menu to play, so it then animates the opening of it. The problem though, that when I put my mouse on the buttons themselves, the menu thinks that the mouse is out of it. I understand that the mouse left the menu itself and entered some other object. I thought of making a new rectangle, and on the mouse out, to check whether the mouse is really out of the menu's regions, it didn't work though.
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 have a movieClip button in my library that I dynamically add multiple instances of to the stage using code (so each instance has a unique name). The button has two frames, so it has a basic rollover effect (just changes color. To make the rollover work, I've had to dynamically add an event listener to each new instance of the movieclip, which triggers the rollover function.
I was wondering, instead of adding an event listener each time, can I somehow have an event listener within the movieclip to take care of the rollover? Or will it not make any difference to the number of event listeners, as it will still add a listener with each new instance of the clip?
I've used a Loader object to add a SWF to my stage. I'd like to attach a listener to the SWF for timer events. I'm wondering what the best way to do this would be. I've been working with this idea but with no luck so far. I thought I could add the listener to the loader content the same way as I would call MovieClip methods.
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 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 have a DAE model that is parsed into several parts. I am able to deal with them separately, such as changing their material or colour but I am having problems adding click or hover listeners over the children. For example, lets say I have a model of a kitty where each facial feature is a child. I want to be able to hover or click the features and have a window pop up explaining the feature. I've tried parsing the model and adding listeners but it doesn't seem to work.
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'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 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'm trying to think of the best way to add event listeners(mouse events) to an invisible object which is quite large. A straight forward way I can think of is probably setting the object's alphy property to 0. However since that object is very large, it will probably have a huge impact in performance. Setting invisible to flash however, will stop it listening to events.
e.g. I have a massive area 4000x4000, but I only want the 2000x2000 area to listen to events.
Other methods I can think of is to have the smaller area in the layer below the big area, covering it from view, though I'm not sure if the lower layer can pick up events? another way is maybe just have the big area listen to events, but in the handler I'll write some code to check if its within the boundary of the smaller area.
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"); }}
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.
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'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'm struggling with a 2 level menu and it needs to follow this condition: The "menuItem" button should be trigged with MOUSE_OVER to open its SubMenu, cause it needs to be also associated with the CLICK event.I'm managing the objects in the display list like this:
stage __menu ____menuItem ______bt_title (movieclip that contains textfield with title of the button)
[code]....
how should I manage the EventListeners ?I've done like that:
I should be able to MOUSE_OVER the menuItem to open the subMenu, and leave it open while I'm still able to MOUSE_OVER and CLICK the menuItem.bt_title and every other subMenuItems.If i do:
Code: menuItem.mouseChildren = false;
then i don't have access anymore to its children. If i do that:
then I get the "epileptic" effect created by continuously mousing OVER and OUT the menuItem. Is there something to do with the capture / bubbling phase of the event flow?Where exactly should I place the listeners?
I want to build a flash based website and place there 4 button MovieClip instances. Once the user clicks a button, all the EventListeners the button attached to (Mouse_OVER, Mouse_OUT, CLICK) are removed until you click another one. Then the previous button gets these listeners back again. One button is always active at a time, so you can't turn on/off buttons.I thought it would be easier to write a ButtonClass and link the button MovieClip to it. But I had to realize that I can't listen that previous button from that class, because it only listens itself obviously. I'm trying to use "dispatchEvent" but I can't get it to work.In the flash movie I have only one frame, 'cause I'm trying to do this without the timeline. I want to use Classes and this and that to practice but I'm stuck with this problem.
I'm making an application that uses a branching tree type structure, and need to get the buttons to refer to and be able to manipulate individual XML nodes. I tried putting a button reference directly in the XML and setting the reference to that node with the event data, but it didn't work, because the XML didn't recognize the event.currentTarget as an actual button, so couldn't find the node that contained the click target. I assume there is a standard way to do this, since it's so common. Just for clarity, the tree will basically look like this:
PrimaryNode1 Subnode1 Subnode1a
[code]....
I need to be able to keep track of which subnode goes where for determining other data as well as graphically positioning the node and subnode data); PrimaryNode2 etc., with add and expand buttons. I can't set static references, since all of the nodes are added through the program depending on if they're needed. I tried doing this with multidimensional arrays, but since I want each level to be theoretically (but not practically) infinite with infinite subnodes, checking through the arrays got kind of messy. I just figured there has to be a standard way to set this up, since it's so common.
I followed a tutorial to build a click-thru photo gallery that is linked to an XML file. The tutorial set up the navigation as being controlled by clicking the images, but I wanted to add some more obvious navigation prompts for viewers on my website. The "next" button was easy to do as I just copied the actions for clicking the images on the main section of the stage, but when it came to building the "previous" button, the code was not working. I want the button to take the audience to the image before the image they are on when clicked.
I've pasted what I have below and highlighted the sections that I have altered. If you could please tell me what I'm doing wrong, that would be great.
I have never messed around with flash before so I downloaded a template. I open it with Flash CS4 and most everything is simple to edit. The problem is I dont seem to find anything about editing the menu/navigation bar.
