ActionScript 3.0 :: Override Alpha Inherited From Parent
Dec 22, 2009
i want to use alpha on a nested object where the hole object act's as one unified element.
i have a main container (sprite) holding some sprite objects with more nested sprites inside them (typical layout structure).
when i use alpha on the main container, flash set all Child objects to the same alpha resulting in an "overlapping" effect rather than one unified object
how do you override the alpha inheritance of a displayObject.
im already setting the cacheAsBitmap to true with no result. my last idea to fix this would be to, precalc the end result, create an bitmap object and position it correctly, hide main container, do the fading, remove image object and set original main container to alpha=1;

Override seems to completely replace a function's code.s there any way to "append" to the superclassed function instead of replacing it?i.e. - so that both traces show in this example:
Code:
package {
public class Top {

is there a way to override a MovieClip's parent and stage properties? In a custom class extending the MovieClip class we can override the get parent() and get stage() methods. But is there a way to do it to existing MovieClip?
I mean I have an external swf content (loaded) and assigned to a movieClip. But now, how can I assign the loaded MovieClip to my custom class, so that it "doesn't see" the parent and stage properties?
Or can I override functions of existing classes? Sth like:
override public function myMovieClip["get parent"]():DisplayObjectContainer
{
...
}
I just need to prevent a loaded MovieClip from having access to the main movie's stage.

I always have a question about override custom event. I am not sure why or what do to inside override function. I searched google but didn't get too many feedbacks. EDIT: My projects seem work fine even though I use my custom event without override. Anyone could explain it?

If I change some value for a parent sprite, the same value will affect all of its children. So if I set alpha or width on the parent, the child will automaticly get the same value.

[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]

I got a "preloader" that creates an movieclip and loads an SWF. Now in the loaded SWF i want a close button to go back to the "preloader". The preloader isn't an actuall preloader but some sort of mainclip.Now i tried this:removeChild(MovieClip(e.currentTarget).parent.pare nt.parent)But i get error:ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.at flash.display::DisplayObjectContainer/removeChild()at MethodInfo-6()

I'm having a hard time calling a method from a particular class within a MVC design pattern. I'm successful at calling the methods from the base (Model) class but haven't been able to call methods from it's subclass (PhotoModel).
My Objective From within the Controller subclass (PhotoController) call a method from my the Model subclass (PhotoModel).
In my document class file I have the following code which connects the two classes together.
PhotoDocument.as
ActionScript Code:
public class PhotoDocument extends MovieClip
{
public var photoModel:PhotoModel;
[Code]....
I thought that defining the model class in this way would declare the PhotoModel class as the model for the PhotoController class, therefore letting me call it's methods and any inherited methods with syntax similar to this; model.method();. Using this syntax I can call the methods in the base Model class but not in the subclass where I've defined additional methods the base Model class does not have.
I've tried a billion different ways to call the methods inside the extended model class but have only a huge pile of failure to show from it.

I have a class (Wall) that inherits from Sprite.Sprite already has width and height properties. But for wall, I need to do some other additional calculations when the properties change (f.e. make sure the new size won't cause it to overlap any other walls).So, how do I set the width property inherited from the Sprite class from within the width setter of the Wall? (or perhaps there is an alternative way to do my bounds checking whenever width is set?)[code]

There's a Loader that I'm filling with different images depending on the button clicked. Now to keep it tidy I'm using the exact same loader. The problem is that no matter what I do to the image, the next image loaded always get's the properties of the previous one. I've used unload and the Loader returns 0 in width and height, and still the next image get's the previous image's w/h. Othe attempts have been separating it from the parent container and taking it out of the display list, and also using an Event.UNLOAD to make sure the previous image is out before the loading of the new image.
Script is gonne kinda long, but the basics would be these,
BrowserLoad.unload();
BrowserReq = new URLRequest("ImageB.jpg");
BrowserLoad.load(BrowserReq);
[Code]....
I guess it's general question: how can i be sure the image previously loaded in a Loader will not affect the next one coming? (its width and height being 0 has not been enough...)

just spotted this curious trick. If you want to flip something to go invisible on a click, and then reappear on another click (etc etc), try this:
create the sprite, setting alpha to either to 1 OR -1
mySprite.alpha=1; //OR
mySprite.aplha=-1;

I am writing this post because i have not found an answer to this. I wrote a class that will get several function names and then proceed to call them. Thing is, i want this code on a base class, which is on a separate swc.
[Code]...
If i override the createThing function, and add the exact same code, there is no problem. Is there a way around this? I think this is a bug on AS3 not distinguishing its real context, but i am not sure.

I was wondering best practices for views of inherited classes in PureMVC in this situation: Multiple classes inherit a BaseClass (lets say InheritedClass1 and InheritedClass2) Each InheritedClass has a respective view (derived from a base view class, but each unique) With a given dataset (lets say ArrayCollection of InheritedClass1/2 Objects), the respective views need to be dynamically loaded. The dataset is relatively large, so a TileList would be nice (since it only instantiates objects which are currently displayed) I can think of a couple solutions, but I find them to be too "hackish" to be the best solution:
In View: Repeater over a BaseClassView which attributes a view to a State (set to the "InheritedClass1" state to add a InheritedClass1 object) Pros: No unneeded memory increase (States' objects are instantiated when needed) Cons: View is dependent on the data types, so adds coupling In Mediator: Loop over the ArrayCollection and addChild() the views based on data type Pros: Works. Cons: Mediator is adding things to the View, which defeats the point of the separation of Mediator and View. Slower than a Repeater.

I made a document class for a project that is similar to this:
package{
public class test1{
// stage assets : these are all objects that were put on the stage in CS4
public var object1:MovieClip;
[Code].....
It seems the inherited class does not want to access the objects on the stage. Is this correct?

I have got to update one of his jobs.It's a set of images that scroll left and right with the mouse and scroll to the left when first loaded, also they enlarge when moused over, oh and they are buttons (this whole 'idea' was thought up by the client with a "I want it to do this" statement), and the code is a right mess.
All I have been asked to do is add an extra image, but I have added the image and the whole thing has broke. With some large gaps being added within the images.Can someone have a look at it and see what's going on, Alternatively i there is a better solution to get the same result (There has to be this looks like some sort of mash of various bits of other code).Links: Ziped FLA, SWF & current live site (about a third down the page next to "chose your favourite sport")

I have the following code:
package { import flash.display.Sprite; import flash.events.MouseEvent;import lib.CustomEvents.ItemLoadCompleteEvent;import lib.Room.Item;import lib.Room.ItemStruct;
public class DragTest extends Sprite{private var itemInstance:Item;public function DragTest(){var tempItemStruct:ItemStruct = new[code].......
I have used the same code with a normal clip and it works. When I use it with my own defined item it does not work. Here are the details.
itemStruct: containing the properties of the item to be made. item : Loads the itemstruct defined item and puts it in a movieclip (item is inherited from movieclip).Traces from the above code, show that only the mouseUp function works mouseDown does not work. Though the same code works fine for a simple movieclip.I have already tried
stage.addEventListener(MouseEvent.MOUSE_DOWN,mouse Down);
EDIT: I have tried put the mouseDown on stage again if I click outside the item and drag from stage it both mouseDown and Up seem to work. But If I click on the item and drag. Still no luck. I have also added the item as movieclip on stage.

Reading a book i stumbled on this example:
Here is the class:
package com.learningactionscript3.loading {
import flash.display.Loader;
import flash.display.LoaderInfo;
[Code]....
What I deduce from this example is that the swfLoader.contentLoaderInfo and _ldrInfo = this.contentLoaderInfo refer to the same object in the same memory location. So you may think: "well the last added event will overwrite the first one (the internally one added). But it doesn't. The two event listeners will respond sequentially. First the internal listener and then the external listener.

I'm currently making a platform game and when the player shoots i want to add the bullets to the stage. The players gun class is in charge of adding bullets. The "players gun" is a child of "players gun holder" which is a child of "player" which is a child of the stage. is there a better or more dynamic way for the "players gun" to add bullets to the stage rather than using parent.parent.parent.addChild (bullet);

I have an actionscript 3 library item, "BG", that is linked to the class BGClass. BG contains a Sprite that has an instance name, "bg" and likewise BGClass has a public bg property. So the class looks like this:
public class BGCass extends Base {
public var bg:Sprite;
public function BGCass() {
bg.width = 200
}
}
Everything works fine. But if I wish to move the public bg into the Base class like this I get the error.
public class BGCass extends Base {
public function BGCass() {
bg.width = 200
}
}
[code].....
I have tried using getter setters in Base and overriding them in BGClass and I still get the error. Is this a bug in Flash? Is there a clean solution or do I need to create some sort of proxy variable to finally get bg to Base? I know that turning off "automatically declare stage instances" in Flash will get rid of the error but I need to keep it on for the designers.
