ActionScript 3.0 :: Duplicate MC Or Create New Instance
Jul 10, 2009
I am trying to get up to speed on AS3.
I am trying to dynamically create a number of click buttons based on the content of an XML file.
So I have a MC (window_mc) which contains a single button (more_details_btn). I add an event listener to send the user to a web page on click.
However. On some items I need more than 1 more_details_btn's. What is the best way to duplicate this MC and assign a new click event and different text.
Below is the code I am currently using and it is causing me all sorts of problems
Code:
for each(var detail:XML in productXML.details) {
var btn = new more_btn_cls();
btn.label_txt.text = detail.@name;
[code]...
Firstly, it wont assign btn.label.text - it says it "Cannot access a property or method of a null object reference" btn in this code traces as an object not a movieclip is that why?
The other problem is that window_mc.addChild(btn); does nothing, yet if I take away window_mc it does add the clips to the Stage. (I need them inside window_mc though)
My problem is that when I click the letter movieclip it does create the duplicate as it should and it starts to drag the duplicate mc. However, when I release the clip it doesn't stop dragging? I realized that if I put onMouseUP event instead of onRelease it actually does stop dragging when I release the mouse. I would, however not like to use the onMouseUP event if possible.
On line 72 of DragGame.as, I have the following function which should place a copy of the selected movieclip in the container_mc movieclip:[code]I don't get any errors on publish but when I click a movieclip I get the following message:[code]I've tried rewriting this function over and over to no avail.
I have a movie clip, that has various codes attached to it to snap to areas of the screen. If I apply the duplicate movie clip command to this, the second instance will have a new name right? so how can I change the code that addressed the original movie clip to relate to the new instance with the new name?
I haven't seen much to explanation of this in any Flash documentation,but maybe someone knows more about this. Initially I was trying tofix a buggy application. The app is fixed now, but I'm still curious.I have an app that defines some object instances (buttons and movie clips)in various frames and on various levels of a timeline. For any object thatneeds to be manipulated by AS, I give it an instance name. However, there's no safeguard against giving several instances the samename. So, I experimented with giving two buttons, on differentlayers and different frames, the same instance name ("playbtn"). Then I defined an event handler:
playbtn.onRelease = function () { gotoAndPlay(1); }
Ive made a FLA that has 360 frames.. on each frame there are 5 instances of a movie clip, each of which ive had to painstakingly position and adjust the perspective of with the 3d tool to make them look like they rotate with the clip. Each of the 5 instances on the stage have different instance names (screen1_mc - screen5_mc).My problem is, after all that frame by frame positioning, ive gone to render out the SWF and its telling me that there are "Multiple 3D objects on the same frame have the same instance name. 3D instance names must be unique. All but one of the instances will be renamed during export."
Soo frustrating. I must have either hit ctrl+v twice on one of my frames or perhaps not renamed the instance after pasting it.. but i cant figure out which frame the problem is happening on. Im really hesitant to have to go through all 360 frames clicking on all 5 of the instances to see which frame is causing the issue.Can anyone think of a programmatical way to figure out which frame has the duplicate instance on it?I was thinking about using an enter frame event to loop through tracing out the frame number, then somehow trace out the instance names and the number of instances of screen_mc that appear on each frame to see which frame has the instance thats been automatically renamed by flash?
have a imageHolder_mc wich is calling the image from the local drive / server, and this container is inside of PictureHold_mc and that inside of Image01_btn.image01_btn.pictureHold_mc.imageHold01_mcand all this for 1 image tobe displayed in the website. But I am going to have something like 300. This is for example HomePage to ProductPage to SpecificIndividualProduct.I have created an instance but DO I NEED TO DUPLICATE ALL _btn and _mc all the way down? Or is there any better ways.And next question. I have done Home Page with 18 images called from the local drive but despite of Preloader showing 100% loaded page look empty for about 30 sec. and suddenly all images starts popping out ramdomly.
I am planning to create Dynamic Boxes, in which may contain buttons, pictures and textboxes in the box. but I'd really want to know are
When a duplicated Movieclip was clicked, I want it to return a value so which I can know what Movieclip was clicked.
How do I manage them in one duplicated movieclip? for example, A duplicated box, and then in that box is an image, textbox and a button MOVIECLIPS, so when dragged, they can be dragged also.
I have a mc that is added to the stage. It extends a dragdrop class. How can I duplicate it so the orig stays where it is and the duplicate is draggable.
I've been playing around with custom classes. My objective was to create a custom class (Testing) that would create a box when an instance of the class is created. I've tried three different approaches, however only (3) seems to be showing up. I'm just curious why (1) or (2) doesn't work?
Also is there a better approach than (3)? Since at the moment it's been created on _root. I hope the box can only be accessible through the instance. Since I'd like to incorporate the whole idea of public, private, encapsulation, etc.
I have a client that is wanting me to create a flash website in which they can add products pages (product info, images, etc.) themselves after the website is completed. I will setup up the first few products then they will do the rest. Would I wanted to go with dynamic text and empty movie clips loading the images? If so how could I have this create a duplicate page that refers to the new text and image?
I am having problems dupliating a movie clip. I can make a duplicate from an original but when I edit the duplicate it also modifies what is in the original. (I am just changing the text, thats the only difference between the 2) How come it effects both clips when I only change one?
What's the best method to put 100 (or 25 or any large number) of movieclip instance on stage & give them all the exact same onRollOver event/function ? Ofcourse with the fewest possible lines of code.
var richiesta:URLRequest = new URLRequest("img/foto1.jpg"); var immagine:Loader = new Loader(); immagine.load(richiesta); addChild(immagine);
Now all works fine but I don't know how to use this image. If I want for exemple change the alpha of this loaded image how to do this? Do i have to make a new instance of it?
I have a movieclip called bg_mc. I don't want bg_mc to show up until I click the btn. When I click the btn it will perform a wipe.Currently I have bg_mc on stage because I need to access its instance name. I can't remember how to create an instance name in AS3.[code]
Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
I have a graphic or movie clip as an example which is a water bottle. An what I wanna do is that depending on what is the user response, in my case is how long the person is doing some activity, depending on that I want flash to generate a number of graphics/movie clips on the screen. As example the person says that takes 6 minutes doing "x" activity, so as a response of a button click which says "generate consumption", it generates on the screen how many water bottles he has consumed for that range of time doing that activity, for example each minute is 2 water bottles, so it has to generate 12 water bottles on the screen when the user press "generate consumption".
If you declare an instance of an object with out assigning it a variable, does it stay in memory or does flash automatically garbage collect it? For example if I just keep using new Date().getTime() to update a persons time from his/her system clock with out assigning it a variable will instances of Date() objects just keep piling up in memory or is it ok to do this?
using AS to draw a shape, or loading in external files to a MC, etc. Basically, they're all overcomplicating it, as far as I'm concerned.
All I want to to is create an instance of a symbol on my stage.Let's say the symbol's name in the library is "picture_mc".How can I create an instance of that on-stage using AS2?
I want to be able to create a movie clip on the fly, inside another movie clip, not duplicate, but create an instance of a clip that only exists in the library. The movie clip that the new clip must be created in is going to have a loadMovie already applied to it, so anything existing in it will be removed. I need a way to insert a clip from the library into this parent mc. I tried attachMovie() but its not seeming to work.
