I am trying to reference a movieclip from the stage which is nested. I really have no idea how to do that.
View 5 RepliesIn a new document when I create a movie clip on the stage and reference it in a script in the first keyframe, like aaa.scaleX = 0.2;, everything works fine.
But when I try this in the game I'm making, I get this error "1120: Access of undefined property aaa.". Why?
In my game I use a document class, here is the code that is executed at the beggining.

I created a custom class in a .as file. I then linked this custom class with a symbol from the library in my .fla file. However, I can't reference stage.stageWidth in my custom class file. I get a null object error.
I think this happens because the custom class file is associated with a symbol on the stage and not the stage itself. For example, if I set the fla file's Document Class to the name of my custom class I can reference stage.stageWidth in the custom class. But I don't do this because I am creating multiple instances of the symbol on the stage. In order to do that properly i found I have to set the class in the properties panel of the symbol to the underlying class which then defines how each symbol behaves.
Under this type of linkage, is there a way to reference the stage width from the class? I've tried root.stage.stageWidth and parent.stage.stageWidth to no avail. I also made sure to import flash.display.* in my custom class. Below is the code for my .fla file and my .as file. In the .as file you'll see the line "x = Math.random() * stage.stageWidth;". This is the line giving me problems. I could hard code it, as I do for the y variable on the next line, but I'd prefer not to in order to keep the code flexible.

I'm having problems referencing the stage from an external class. I've tried :
Code:
stage.addEventListener(MouseEvent.MOUSE_UP, onUp, false,0,true);
And also
Code:
MovieClip(parent).addEventListener(MouseEvent.MOUSE_DOWN, onDown, false,0,true);
But no luck. Can I not do this? I'm making a pencil class that I want to be able to reuse. I also tried "this" and while it didn't throw and error, it didn't work either.
I have a movieclip "submenu" that is on the main timeline, and inside this movieclip, I have some ActionScript:
[Code]....
I'd like to know how I can reference root stage values from within a movieclip, or even worse, from a class. For example, I have a class called Bground.as. It does stuff, according to current stage size - so if someone were to resize the window/browser, Background updates in real time and does something fancy while it's at it. To do this "fancyness", I need stageheight and stagewidth. However, simply pointing to them does not work.
Here's the simplified ActionScript Code:
package klaseFP{
// imports
import flash.events.*;
import flash.display.*;
public class Bground extends MovieClip{
[Code] .....
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at klaseFP::Bground()
at FullScreen_03_fla::MainTimeline/frame1()
Background works as a document class, works perfectly in fact. However, if I use it as the class of a library object, error 1009 shows up. Same thing happens if I simply put the code into the timeline of the library object - stage referencing simply causes it to break. So, how do I dynamically change the values of variables in Background, according to values in the main movie/app?
I feel like I should know this by now, but I'm having trouble. I want a function in one of my child functions to increment an integer in its parent function.

i'd trying to build an interactive tree that allows the user to move the tree's branches and nodes. the lines (branches) of the tree are drawn programmatically between points (nodes and tips). i'd like for the user to click on points to drag them while having connected lines and points move correspondingly. i've gotten this to work to some extent using the code below:
ActionScript Code:
function startMoveOa(evt:MouseEvent):void {
thisPtOa = Sprite(evt.currentTarget);
[code].....
Just wondering, is there any way to dynamically reference movieclips on the stage, as in through a for loop like so:
for (var i = 0; i < 10; i++) {
["mc" + i].x = 10;
}

I have been trying to reference to the stage from outside Document class and tried many different ways I found on google and it seems none of them works (maybe there were some changes in flash since they were posted.For example TopLevel approach by Senocular doesn't work either I do it as described in here.URL...The only way it seemed to work is by passing a stage as a variable. Has anyone any idea of a way to do it without the need of passing it by.
View 7 RepliesI have just recently started playing around with AS3 and am pretty new to what is going on in Flash (though I do have a lot of programming experience.) I have an object that I am dragging around on the mouse. I want it to be destroyed if I drop it anywhere but in a target location. I have the part where it is destroyed working, but I am running into a problem trying to find the target. When I try the following...
PHP Code:
public function DropObject(){
if (! this.hitTestObject(stage.getChildByName("Target"))){
stage.removeChild(droppedObject);
stage.removeEventListener(MouseEvent.MOUSE_MOVE,droppedObject.MouseCursorMove);
}}
I get "TypeError: Error #2007: Parameter hitTestObject must be non-null." So, "getChildByName" is returning null, but I'm not sure why. I've verified that there is an Instance name of the Target on the stage. Why can't I find it?
I have a media player that I am codging together, one that will play either videos or MP3s depending on the variables it is passed. The video player part works fine. The MP3 player controls are all actual physical MCs on the stage; each one has its own AS class file as part of the package, but there is also a lot of AS that is happening in the main FLA as well. Messy, I know, but it mostly works great.
The MC on the stage in the main FLA is properly linked to the class file via Actionscript linkage, and the control itself works. However, I am trying to make some aspects of the control respond to variables that are set within the AS on the timeline of the main FLA, and I cannot seem to pass values to the control no matter what I do.

View 2 RepliesOn the main stage I have a button that I have made invisible once the file is loaded. Inside a movieclip I have on frame 15 the following actionscript 3 code

I want the button to become visible at the end of this movieclip. I am not using an external as3 file, I am putting the as3 code in its own layer on the first frame.
I know it has something to do with the path to the button, but I cannot figure it out. If there is anyone who can point me in the right direction for referencing instances by instance name that reside on the main satge from inside a movieclip

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 can get an error-free compile if I take the seemingly unrelated TLF text box out of the equation, either by changing it to a classic text box, deleting it, or unlinking its containing MC from MyClass.
I can also get rid of the error by removing myOtherFunc()'s definition or moving it below myFunc()'s, which I had to do a few times just to convince myself that it was true.
Update: I just confirmed the same behavior on a friend's version of CS5. He's using a Mac as opposed to my Windows setup, and he only has the CS5 version installed, whereas I have both CS5 and CS4.

How can I refer to the global trace method in the constructor, and not TraceTest's method?
does anyone know if there is any possibility to do simple elementwise math on bytearrays without having to program it explicitely, e.g. a built-in function for multiplying all elements of a bytearray (of type float) by a constant or adding the elements of two bytearrays (with specified datatype)?
