ActionScript 3.0 :: Set Parent Variable From Object?
Apr 1, 2011
I've got an external class and make like 20 objects with it. If I e.g. hover my mouse above them, the objects themselves know that, the parent clip however does not. Now I want a global boolean to be set to true, if one of those objects is focused. So in other words I want to set a parent variable from inside of an object that I created with a class.
I could make myself an enter-frame-loop and check all of the objects all of the time, but that doesn't sound like a good solution.
I could also add 20 change-listeners to the parent clip, but I'm not sure about the performance of that. And I have listeners inside the objects anyway, so those should be somehow able to take care of that, or isn't that possible?
I've been trying to use the object.watch() method. I've never used this before, so I'm assuming I'm pretty far off base here. What I have is a parent movie (_root.) that has a bunch of variables. As the user progresses through the movie/project the variables change based on the user's actions. Within this parent movie there is another movie embedded. In this movie, things change based on the variable changes of the parent movie. So, for instance, say the user gets through frame #20 and hits the "next" button in the parent movie, this triggers a variable change in the parent movie, which then causes the embedded movie to change its color from blue to red (or whatever, action doesn't matter)
I want to listen for a custom event dispatched from the document class in a custom subclass. For example, let's say in the document class I have:
ActionScript Code:[code]....
So that the subclass will trace 'Event from document class received' when the 'customEvent' event from the document class is listened by the eventlistener. However, the output is only 'customEvent dispatched', meaning it wasn't heard in the subclass.
I am calling on different types classes from within a loop. The objects can be of different types so therefore I am using the getDefinitionByName method. here is a piece of my code:
for(var y = 0; y < mapH; y++) { brickHolder[y] = new Array();
[Code]....
But I got an error when I tried to call on methods. The interface is blank; doesn't have any methods in it. I am not sure if that makes a difference. But the parent class inherits it and the subclasses inherit the parent class. Can I instead use the parent class?
var brick:ParentBrick2 = ParentBrick2(new classRef());
In a nutshell, what can I do to loosely cast these objects so I am able to use any subclass methods that get called?
[code]All clips are squared.Ok, on the PlayerPlane, there are little soldiers, which have hotkeys. The effect I'm trying to create is I want to position the GameStage so that the currently selected soldier appears in the center of the GameClicker clip.The GameStage is movable by the player (to scan other areas of the map)by holding the CTRL key, so it's easy to kinda lose track of where your players are.I have tried using localTo Global and globalToLocal techniques, but I think I'm lost on the actual math of getting the GameStage to move the correct distance so that the selected soldier is centered to the GameClicker.[code]
This is probably a fairly easy answer, but I can't figure it out. I have a dynamically added child, and I have a dynamic text box on the parent. I'm thinking that it should be possible for me to add to the text box from the child timeline, but I don't know how to target the text box.
Is it possible to pass a variable from child to parent movieclips. I can pass it from parent to child but not the other way around. I have a main movie which loads a child movie: loadMovieNum("slides.swf",1); I want to pass variable from slides.swf to the main movie. Is this possible?
ActionScript Code: function createMaskBox():void { var maskBox:MovieClip = new MovieClip(); galleryContainer.addChild(maskBox); }
creates maskBox under the function therefore not accessible form outside of this function from what i understand. Is there a way to create a var WITHIN a function which would exist as if defined outside of it, directly in code?
I have an app which basically has a page with 2 entry points - each of these entry points needs to pass information into the same variable (colourName). The only way I can envision doing this is to put the variable in the parent class - which for some reason is modifyable and will trace details, but once I've removed the child, and added the new child, the variable returns a null object error!
I have a simple BOOK script where I have 10 pages (for example purposes). Each page has a vocabulary word on it. Currently, I simply created a vocabulary MC separately for each page and it works fine. Problem is, that leaves me with 10 Vocabulary pages and I would rather have 1 that loads info based on a var on the main page.
WORKING SCRIPT var loaderZ:URLLoader = new URLLoader(); loaderZ.dataFormat = URLLoaderDataFormat.VARIABLES; loaderZ.addEventListener(Event.COMPLETE, loading);
[Code].....
I am getting the word "depressed" from page 1 (verified by trace) Unfortuntely this does not work.
If I change the last line of code to:
VocText.htmlText = loaderZ.data = word;
Then it outputs the word DEPRESSED to the text field VocText but does not return the value from the txt file.
I'm also relatively new to programming with actionscript, so my code might look quite messy to you Here is my function. It loads the contents of an .xml file and creates a playlist for a video player. Now my problem is that i want to set the "onRelease" function dynamicaly for each playlist item. but inside the onRelease-function i cannot access the variable i. do you have a hint / workaround for me?
I am getting the following error:1119:Access of possibly undefined property through a reference with static type TenI am explicitly casting, and tried this.parent and still get the same error. What am I doing wrong.
Here is the code: package { import flash.display.*;
For instance, in the below code a parent can control a SWF child's function "alert ()". But how a SWF child can control parent's function "ReceivingChildMsg()" ?
I have a public variable set within fx:Script tags in a parent component that I'd like to access directly from a child component. How can I do this? I don't want to pass the variable to the child component (I know how to do this and am currently using this approach). Following is a simplified version of the mxml:
Note: SimpleComp is an HBox with a couple of lists. <mx:Accordion> <comp:SimpleComp/> </mx:Accordion>
Assign an event listener to a protected timer variable in the parent class.
I am working with Adobe LCCS, and created a BatonProperty which implements Baton
Now, Baton has a protected timer variable declared like this, and for some reason, I am unable to get access to this _autoPutDownTimer, from a BatonProperty instance.[code]...
is there anyway to create and define a variable in a child from the parent? For example, if I add a child to the stage with code, and then want to be able to say
child.variable=0
to create a variable in the child and be able to edit and read the variable. I know the above code is way off but it's just to kinda get the point through.I have to define the variable this way.
I'm coming to Flash from a mixed graphic design / 3D animation / motion graphics background. In any of the animation programs I've used before, including After Effects, parenting is a simple operation. ...But it seems that in flash, it's more complex. So far, I am beginning to understand that it has to do with nested scenes, or nested time lines (which may be the same thing?)... So my question is... What is the easiest way to parent one object to another?
