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);

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.

I have a main.swf and a slider.swf. I load the slider.swf into main.swf. In my slider.swf I have this code which adds an image to the stage from the Library:

I assume it has to do with the stage.stageWidth. Is there a another way to reference the stage. If I load the the image externally via a loader I can use the stage.stage Width.
On 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
button_mc.visible = true;
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 would like to know the way to prevent a child swf from referencing its parent swf stage width/height?
for example, i created a child swf that loads image and center it on it's stage. As a stand alone its fine but i loaded it with parent swf, it centers on the parent swf instead.
Ok, this is one of those walls that I know once I can jump over it, I will be a much happier developer again.
I've done tons of reading, and think I have a firm understanding that the general consensus is that if you want to reference something, it needs to be added to the display list, using addChild().
I hate to be defiant, but what if I don't want to?
Or at the very least, what if I want to add a movieclip class to the stage using addChild, and then reference objects inside it?
It is much easier this way than what most people recommend - adding 15 objects via addChild, then setting the x and y for the, etc.
That said, I'm all about using classes and using as3 the way it was meant to be used. So what this is, is a best practices question I guess.
HERE ARE THE STEPS I'M TRYING:
- Create new flash document
- Draw graphic symbol bg, with text field over it, select them, convert to movieclip symbol, and export class name "box", then delete it from stage
- Add document class .as file, which simply adds that class "box" from the library, to the display list using a simple addChild()
- Set a name for that box using box.name = "test" let's say
- Do a simple trace like the following - "getChildByName('test').textFieldName" - it shows up great
- So then, I'll now try to set the text by doing this - getChildByName('test').textFieldName.text = "yo";
That last line above, is what doesn't work. I know I'm referencing wrong, but how would a pro as3 developer, reference something on the stage within a movieclip class, from the document class?
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);

[CODE]...
I haven't gotten a handle on coding classes and the appropriate syntax with all the "public" "private" "static" keywords, etc. Anyway, one thing I miss in AS3.0 is having "out-of-the-box" global variables and functions. I've read a lot of forums and articles about making a simple "MyGlobal" class that could hold variables and functions which could be called from the timeline as "MyGlobal.doSomething()" However, I seem to be running into a problem trying to reference "stage" from within one of the global functions... I imagine this is because "stage" is an instance property. I'm basically trying to add/remove an event listener to the stage whenever the global function "MyFunction" is called.

I am new to AS3 and trying to figure out how to set a focus to a textfield on the stage. I found out that if I use stage.focus = tf; then the tf get the focus and it does, when I type letters they go directly to this textfield.Problems are, I don't have a blinking cursor in the textfield. I added event listener to catch up when the user press the ENTER key but it catches the ENTER key ONLY after I click the textfield with the mouse and having a blinking cursor in that textfield.
