Flash :: Check If DisplayObject A Is A Descendant Of DisplayObject B?
Oct 26, 2010I 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 :: Convert Global Coordinates To Local Coordinates Of A UIComplenent In Flex Project?
Dec 19, 2011I was trying to convert global coordinates to local coordinates of a UIComplenent in my flex project using below code using below code
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
uic is UIComponent in which I have subclass of Sprite for drawing something I have set the sprite's mouseEnabled and mouseChildren to false to not interrupt the mouse event. above code is within uic's mousemove event where I was tracing the gp and lp gp was giving correct value and suprisingly lp was giving negetive values. when I move the move to the top left corner of uic i expect lp to be 0,0 but it is giving the -width of of uic. I broke my head for hours and ended up finding an alternate by using offsets. Infact my original code was much simpler like this which was same issue
var lp:Point = new Point(e.localX,e.localY);
I am not sure what exactly is causing this problem. the workaround had lot of issues and it creating a mess in my rest of the algorithms.Just now I found even more interesting thing (which is actually weird). for some reason I went and create a new lp2
var lp2:Point = new Point(e.localX,e.localY);
now surprisingly it was giving correct values as expected and I went back and changed the code as
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
var lp2:Point = new Point(e.localX,e.localY);
var lp2:Point = uic.globalToLocal(gp);
now it is expected to have all the lp, lp2 and lp3 variables to be same but weiredly lp two is giving wrong value and lp2 and lp3 were giving correct. I am suspecting using the variable lp has something to do. I am not sure about that but above proves it so right now I am using lp2.
ActionScript 2.0 :: Converts 3d Coordinates To 2d Coordinates - Difference Between MoveTo And LineTo?
May 21, 2007I was reading the 'Isometric Transformations' tutorial by Danko Kozar and I have a few questions. I understand what all the code does, but not how it does it. First of all, how does the following code work:
transforms x,y,z coordinates into Flash x coordinate
xFla = function (x, y, z) {
// cartesian coordinates[code].....
I understand that it converts 3d coordinates to 2d coordinates, but I don't understand how. What numbers whould be punched into x, y, and z to acquire certain desired effects?Also, what's the difference between moveTo and lineTo:
red line
style(1, "0xFF0000", 100);
plot(0, 0, 0);
draw(200, 0, 0);

View 2 RepliesActionScript 3.0 :: A DisplayObject Becomes NaN?
Apr 8, 2010I've come across a pretty bizarre bug in my code when working with level generation in a side-scrolling platformer I'm trying to make... I've been desperately trying to debug it for the past 2 days! I have a movieclip (exported for AS) called Section1, that contains the first section for a level. It's basically a huge movieclip containing other movieclips; this Section1 movieclip contains the graphics for the level, as well as collision detection (the graphics are .pngs converted into movieclips, the collision detection is transparent rectangles converted to movieclips). FYI, it's a BIG movieclip... roughly 3400 pixels wide.
So, since it is the 1st section of a level, I have it spawn at the beginning of the game. However, I need to access all the platforms, walls, and graphics inside section1 from inside AS. So, here's the code I am using to do this:
public var s1:Section1;
public var platforms:Array, walls:Array, levelGraphics:Array;
...
// in Main's constructor now:
s1 = new Section1(2236, 8);
[code]....
Initially, it works... I've traced the data in the arrays in my update method (run every frame), and I can see that the arrays contain displayobjects... for a split second, that is. Seemingly out of nowhere, the values for all the elements in the arrays become NaN! I think to myself... of course these DisplayObjects are "not a number"... they're displayobjects! Of course, this renders my arrays useless, since I can no longer access the data I need to do collision detections!

ActionScript 3.0 :: DisplayObject Being Orphaned From Parent?
Feb 25, 2009Firstly, I've created a global variable called mc to store a movieclip instance:[code]Later on inside a function, I've created a new instance of my movieclip and added it to the stage.[code]Now, this is working fine most of the time. But at one particular point in my program, after many other things have happened, when trying to remove this movieclip it throws the 'display object must be a child of the caller' error.So, I'm thinking if mc isn't a child of the stage, what is it a child of? Tracing mc.parent returns null - so it seems to be telling me that the parent (which was definitely the stage when it was created) has wandered of somewhere and abandoned my movieclip!I have no idea how this has happened, and as the whole program is several thousand lines long I can't post it here. So, does anyone have any idea what might cause a display object which is added to the stage to become orphaned like this?

Flash :: DisplayObject Snapshot In Flex 3?
Jul 9, 2009i'm creating a visual editor in flex and need to let users export thier projects into Image format. But i have one problem: size of the canvas is fixed and when user add element which is out of these sizes some scroll bars added. And user continue working on the project. but when he want to take snapshot of the canvas he just get the visible part ot the canvas with scrollbars. how to get image of the fullsize canvas?
The only solution i found is to check the positions and sizes of canvas child objects and rezise it to fit them. then take snap and resize back. But it hmmmm... too complicated i think. Is there some "easy methods"?

Flex :: Inheriting Properties From A DisplayObject?
Dec 21, 2009In regards to as3 project: Is there a way to inherit the properties of a given DisplayObject? I am looking for a single method that will grab something like the x, y, width, height, color, etc. Whatever is involved in the common classes between the two display objects.
Edit:
I don't think I was clear enough... Let me give an example of the type of functionality I am looking for.
var sp1:Sprite = new Sprite();
sp1.x = 30;
sp1.y = 30;
sp1.width = 500;
sp1.height = 30;
var tf1:TextField = new TextField();
tf1.inheritTransform(sp1);
So, in this case I know that the method 'inheritTransform()' doesn't exist, but I am wondering if there is something similar. Or maybe I am missing the point of extending a class in some way? I don't see how the two would relate in such a case.
