Flash :: Does The Display Index Effect The Scope Of An Object
Jan 29, 2010
know if the index effect the scope of an object because I am creating a game and for some reason, I get an error like below
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.objects::Torret/updateObject()
at com.objects::EngineApi/loop()
[Code].....
updateObject is the loop for all my objects. I have one centralized loop and in that loop it calls on an array of objects that have been placed on the stage. all of them containing the method updateObject. to update the status of the object. addGameChild() is a encapsulated addChild() , that not only adds the object to the stage, but places it in a array so it's updateObject() method can be called on. it is also used to make it easier for garbage collection.
Assume I have an array with references to different display objects on the stage. The display objects do not have any other explicit references except for the array indexes. How do I evaluate if a certain index of the array is a reference to a certain display object?Some code to clarify:
I have a set of buttons which trigger menu panels to tween up from below the screen. I want these menu panels to be displayed behind the buttons (which are displayed on the button edge of the screen). So I add the menus to the parent container, then I add the buttons, so that the menus would be behind the buttons and getChildIndex(buttons) = 1 and getChildIndex(menus) = 0.
The menus are correctly displayed behind the buttons when I comment out the tween code. But when I implement the tweens and start the tween of the menus, they do their motion tween but are displayed in front of the buttons instead of behind; somehow their display object index order got screwed up.from the Menu class:
This is a situation: i have a index.swf in which i have holder movieclip in which i load gallery.swf (where i load pictures in it's holder mc). The thing is i used _root in gallery.swf so when i publish it separately it works, but it doesn't work within index.swf. I suppose there is a scope problem where _root adresses _root timeline of index.swf instead of gallery.swf when index.swf is published and gallery.swf loaded inside. I tried to solve this by putting: Code: this._lockroot=true; inside of gallery.swf but now my Flash 8 player just freezes when index.swf is published and gallery.swf loaded into it but i have no idea why? What would be other solution for this problem?
I'm working on writing a tweening class in as2 that has a callback variable and I can't seem to find a good way to get the scope without specifically passing in a scope variable as well. This tweening class needs to work in classes as well as on the timeline. Here's what my codes looks like right now.params.scope[ params.onComplete ]( params.onCompleteParams );params is an object passed into the class. This works but I don't want to have params.scope in there.
I have swf object with z-index:-5; position:absolute; Also a div with ul in it where div has also, z-index:5; position:absolute; All browsers display div over my flash except IE9.
I am developing an application to display different time zones. Class works fine only once, later it fails to update the movie with dials of clock. I not sure what could be the issue, I am using delegates as methods weren't called previously.
In the first function homeL adds the 'restMenu' text field when it's called. In another function the hideTarget method is called and it checks to see if the objects name is "instance5" which is the name of homeL. Is there a way to link an objects name to the object because I get :
I'm using the jQuery oembed plugin to display videos from a Vimeo feed. The only problem is they display over the top of my navigation menu. I have tried setting the z-index of the menu but this makes no difference. A common suggestion seems to be to set the wmode parameter to transparent or opaque. However, passing this as a parameter to the oembed function makes no difference.
how do you find an object's index / position within an array in flash actionscript 3? I am trying to set a conditional up in a loop where, if an object's id is equal to the current_item variable, I can return its position within the array.
I have the following divs and I'm trying to make the iframe layer infront of my_flash. It's a common problem and I've read through all the solutions I could find and still I'm getting issues in IE8. I'm using SWFobject by the way.
After chatting with my coworkers, they have suggested I enumerate this into a large array of indexed values with references to which index they are associated with, for instance [code]...
I have a Debug class I've written, and I'd like to include a static trace() method in there, unfortunately I have no idea how to then access global / top level trace as effectively I've blocked it with the local static scope.[code]
If I create a rectangle with 100px width and 100px height and then rotate it, the size of the element's "box" will have increased.With 45 rotation, the size becomes about 143x143 (from 100x100).Doing sometimes like cos(angleRad) * currentWidth seems to work for 45 rotation, but for other bigger angles it doesn't.At the moment I am doing this:
var currentRotation = object.rotation; object.rotation = 0; var normalizedWidth = object.width;
I have a simple object defined by an object literal, and have a couple functions assigned to this object. Inside the functions, I try to access global variables, and it only gets undefined. The Flex debugger tells me the variables are just right up the scope tree.Yes, I know I can access Thing by using 'this', that doesn't solve my scope issue though.Project Flex Compiler Settings: Flex SDK 3.4, Require Flash Player 10.x.Example:
You will find enclosed a ".zip" file in wich there's a ".fla" file, a ".txt" file and 6 ".jpg" images. Frame 1 of the FLA only has a "Preload" class/constructor found on another site and works well. Frame 2 launches the graphic interface construction. The file "externalVar.txt" has one variable "maxVin" with a value of 6.
I would like to know WHY i can't acces this variable from outside of the loadVars object's scope (i would better say from outside of its ".onLoad" methode scope). In fact, when i trace my variable "maxVinNum" from outside of this function, flash player return "undefined". Even if i declare "maxVinNum" on the _root (_root.maxVinNum). For information, at the start of frame 2, i have let an instruction in comment: //var maxVinNum = 6; When we activate this instruction, then the variable is directely declared and everything works well. This test allow us to verify that scripts are not bugged. Here is the script of frame 2, some of you may understand quickly what's wrong :
I'm working on a project for a website, I need to display statistics in a flash video, and as easy as it sounds, I can't get it to work. Basically, I need some text to fade in, and the actual number to count up [from zero to the number]. I managed to get it semi-working, but I can't get the numbers to fade in. I didn't know if there was any easy way to do this without doing it frame by frame.
How can i cast a object to another type? in AS3 i tried putting (objectType) infront of the variable but it doesnt work, below i have added objects of fishes into the child, and i am getting the fishes back out when mouse down is triggered, and then calling the fishes what to do. however i cant call the method of the custom class fish because it is a displayobject.[code]...
Is there a direct way to get the item index of the data inside an itemRenderer? I need to display the item number against each item. I am currently doing a workaround and won't allow reuse of my itemRenderer component.
var index:int = model.dataColl.getItemIndex(data) + 1; itemNo = index.toString();
This is what i am using now, it works, but the concepts of component reuse and data abstraction are compromised.
in a nut shell I have found this wicked piece of open source actionscript.
It responds to the cursor and was wondering if it is posible to modify the x_position and y_position actions and make the action respond to a moving object???? (a movieclip with a variable name)
is this to complicated to attempt or is it doable??
I have a div with a flash object in it. That div is going to pop up in a modal triggered when a user clicks a thumbnail of the flash presentation. The problem occurs when I try to use the scale effect to scale in or out, it errors out.
Here is the HTML: <div id="modal"> <object id="presentation" width="720" height="576" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="[URL]" align="middle"> <param name="allowScriptAccess" value="sameDomain" /> <param name="movie" value=" video.swf" /> <param name="quality" value="high" /> [Code] ......
Like I have a parent with 5 children which are the same type of object, like the same class. Is there a function or property that tells me what index this particular child is in its parent? Like this child is the 3rd child in its parent.
