ActionScript 3.0 :: AddChild() - DisplayObject Isn't Visible Immediately

Aug 17, 2011

When I add a DisplayObject to a DisplayObjectContainer (e.g. a Sprite to a Sprite) in a function, it seems that the DisplayObject is actually added not immediately, but after finishing the function.

See this example:

Code:
package {
import flash.display.Sprite;
import flash.events.MouseEvent;

[Code].....

So we have a simple green button, and when it is clicked, there's a red Sprite constructed and added to the stage. But actually the red Sprite isn't visible until the onClick() function has been fully executed.

Why is that and what can I do for the red Sprite to be visible immediately?

Is there some (for the developer invisible) global paint() or update() function, that is not executed until some stack is fully executed or something?

Flash :: Get Visible Size Of DisplayObject With Perspective Projection

May 2, 2010

The following is entirely a math question. As we know, PerspectiveProjection delivers perspective transformations in 3D represented by the interdependent values of fieldOfView and focalLength according to the following formula:

focalLength = stageWidth/2 * (cos(fieldOfView/2) / sin(fieldOfView/2)

Q: How to get the visible on-screen size of the DisplayObject (Cube on the above-linked image) to which PerspectiveProjection has been applied? A more thorough description and illustrative code on the issue in ActionScript 3 lacks functionality for visible bounds of DisplayObject.

Actionscript 3.0 :: Scale DisplayObject Based On Visible Bounds

Nov 5, 2010

I've been banging my head trying to figure out how to get this to work with no success... I have a class that extends MovieClip which loads a large image into it. This image has a mask applied to it to only display a specific section of the image. I need to be able to scale this MovieClip based on it's visible width & height while maintaining it's proportions.

I'm currently using Collin Moocks' approach (see it here:[URL]) to get the visible width and height of the movieclip, but I can't figure out how to get it to scale correctly based on those dimensions... Preferably I'd like to be able to set it's visible scaleX & scaleY properties similar to how you currently set the scaleX & scaleY, (i.e. movieclip.visibleScaleX = 1.5).

ActionScript 3.0 :: DisplayObject And AddChild - Use The Variable OpenType In The Call For The Image??

Nov 24, 2009

I am working on a project where we are making a "wizard" where you answer a series of questions and in the end you are presented with a "parts list" based on your answers.There is also logic which decides which questions you are asked based on how you have answered certain questions so far. The outcome is a list of door control hardware (locks, mounting plates, handles etc. etc.). show a "live image" of the parts list as it builds. For example one of the questions is this: Door Type?

A) Aluminum

B) All Glass

C) Wood

Depending on which you choose I need to show an image of an aluminum, glass or wooden door.Then if the next question is about lock types then your new lock shows up and so on and so forth until you reach the end.The questions all relate to their own variable which are each defined at the beginning of the movie like this:

Code:
var doorType:String = "DT0";

The questions use radio buttons and each question (re)defines it's variable like this

Code:
DT1.addEventListener(MouseEvent.CLICK, doorTypeHandler);[code]....

Now the tricky part (for me at least) is figuring how in the world to use this in conjunction with the questions (more accurately, the variables they define) to produce this live image.Another thing to add complication to this whole mess is that there are basically two entire sets of images. Single doors or Double doors, they both have (nearly) all the same hardware but they are two different sets of images. They are differentiated by the ot1 or ot2 in front of the class name. The variable openType defines OT1 or OT2 in a previous question. I would like to be able to use the variable openType in the call for the image

Code:
//This is how I tested it
currImage = new ot2_wood_exit();

//I would like to use openType instead of hard coding ot1 or ot2

currImage = new openType_wood_exit(); //I KNOW this is wrong, but I don't know what is right!So that is my basic dilemma. I need to show or hide specific images based on the answers to previously answered questions AND questions currently being answered (live update).

ActionScript 3.0 :: Flash DisplayObject Container Matching All Elements With AddChild() On Criteria?

Mar 1, 2012

I'm coding this minigame implementation where a sprite traverses tiles on a screen, and when he's done traversing a tile, the tile "disappears" (its alpha decreases and it becomes a "wall" the player can not move onto). Now, simple enough. Make use of a traversing and traversed boolean arrays to store if a tile is currently being traversed, or if it isn't, but it has been traversed. So, if traversing == 0 and traversed == 1, make the tile "disappear". However, and here's the weird part, if I just set the alpha to, say, 0.5 in this if statement, it sets the alpha on just the tile I traversed, whereas if I try to make it part of the wall as well (in the same if), every tile except the one I've traversed to becomes a wall.

Here's part of the code (it happens in the enterFrame game loop):

Code:
const NUM_TILES = 15;
//Add MC for all the tiles
var tiles = new MovieClip();
addChildAt(tiles,5);

ActionScript 3.0 :: MovieClip AddChild - TextField Not Visible?

May 8, 2009

I have a movieclip, an image at the same size as the movieclip (it's like the backgroundImage of the mc) and a textfield. I have first created a movieclip object 'my_mc' then I loaded an external image 'ld_image' I created also a TextField object 'txtField' with backgroundColor red
then I did:

Code:
my_mc.addChild(ld_image);
//my_mc size = ld_image size
After that I did:
Code:
my_mc.addChild(txtField);
addChild(my_mc);
but now the txtField isn't visible but my cursor changes if I go over it with my mouse.

Flash :: Check If DisplayObject A Is A Descendant Of DisplayObject B?

Oct 26, 2010

I would like to be able to quickly check if a given DisplayObject is a descendant (not in the inheritance sense - ie. child, grandchild, great-grandchild, great-great-grandchild, etc.) of another DisplayObject. There doesn't seem to be a native way to do this and I can only think of two ways to achieve it: Create the mother of all nested loops. Seems a bit, I dunno, wrong? Dispatch a bubbling event at the 'child' and check if the potential 'parent' receives it.

ActionScript 3.0 :: On Click Object Visible Not Visible

Aug 8, 2010

I want to click on an object and make it appear and disappear. As the object is rectangular, I figured putting a white button the same size on a white background on a layer underneath the object would do this, but I can't seem to make it happen.I'm a complete novice, frustrated as I've been trying to achieve this all day and I'm sure it should be pretty simple, but could you give me the idiots guide. I know how to name an instance, make an object, script in actions on a separate layer. I would like to draw the button myself and give it an instance rather than drag it off the button component (as I can't work out how to make the component button white, change its size etc.!)

Okay, this should be relatively easy but I'm running into errors. My main character is visible in the beginning of the game (where the main menu is) and because I coded it so that all of the enemies don't spawn unless the main character is visible, the enemies spawn too. As a result, if you stay at the main menu for long enough, the score continues to go up, the health goes down when enemies attack, etc.

ActionScript 3.0 :: Load External SWFs, AddChild(Loader) Versus AddChild(Loader.content), Etc?

Jul 29, 2009

I have a main "shell" swf which, by clicking several buttons, will load/unload various external swfs into a Placeholder_mc which resides on the main timeline in Shell.swf In the documentation and tutorials I've seen a couple different methods, and I'm not sure I quite understand the difference, or at least the reason you would use one over the other...In the 1st method, you can just add the Loader object using the addChild() method:

Code:

var myLoader:Loader = new Loader();
var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf");
myLoader.load(myURLRequest);
Placeholder_mc.addChild(myLoader);

This will apparently add myLoader to the display list once it has completely loaded.The 2nd method, you supposedly can add the Loader.content; however, it appears you can only do this once the content has completed loading, so you need to incorporate an event handler with the contentLoaderInfo object:

Code:

var myLoader:Loader = new Loader();
var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf");
myLoader.load(myURLRequest);

[code]....

What are the pros/cons of adding the entire Loader object, as opposed to the Loader.content and vice versa?

Flex :: Air - Dialog Not Display Immediately?

Sep 11, 2009

In an AIR application I have the following code:

theDialog = PopUpManager.createPopUp( this, TheDialogClass, true ) as TheDialogClass;
theDialog.addEventListener(FlexEvent.CREATION_COMPLETE, cpuIntensiveCalc);

At the end of cpuIntensiveCalc the dialog is removed. The dialog informs the user that "something is going on, please stand by."

The problem is that cpuIntensiveCalc starts before the dialog draws. So the user experience is that the application freezes for 10 seconds with no indicator, then the modal dialog flashes quickly (less than a second) on screen.

The Adobe docs say this about creation_complete

Dispatched when the component has finished its construction, property processing, measuring, layout, and drawing.

So this feels like the correct event. In the name of completeness, I also tried

theDialog = PopUpManager.createPopUp( this, TheDialogClass, true ) as TheDialogClass;
cpuIntensiveCalc();
