ActionScript 3.0 :: Connect To The Same Class From The Stage As Well As From Inside A MovieClip?
Aug 7, 2011
How do I connect to the same class from the stage as well as from inside a MovieClip?
In other words: I've set a document class in my properties panel - I cannot access the class's methods from inside an MC. Why?
What are the different ways to connect a fla-file to a class (as-file)?
I've been playing around with AS3 for a few years now, but always avoided classes. But now the day has come for me to finally trying to get a hold of it.
Ive been working on a project at the momment and ive been having an issue with accessing a MovieClip that has been created in another file called fileA and i want to access it from fileB the only Problem is that FileB Doesnt know it exists in FileA and it returns back this error
Code: Error #1009: Cannot access a property or method of a null object reference.
Code below is in fileA
Code: public var ChangeControlMc:MovieClip = new control();//This one is defined in FileA
My Code for FileB is as Follows
Code: public var ChangeControlM:AntarcticaGame // this is Defined in fileB trace("test level 1"); trace("called after super save()" + ChangeControlM);
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?
On the stage I have a movieclip called mc_back. I also have a movieclip on the stage called mc_content. Now, inside mc_content I have a bunch of code and some of it adds, or should add, an EventListener to mc_back as well as a a function that works when mc_back is pressed.
So basically, all code is written inside mc_content and some of it needs to interact with mc_back.
how to target mc_back from inside mc_content. Using stage.mc_back or root.mc_back doesn't work and Google should be my friend, but in this particular problem, it's acting more like my enemy.
In simple example, I have a class called RedSquare that extends a Sprite. I need to have it in a central position of the stage. I do not know if importing definition of Stage class to RedSquare changes anything, but in the constructor of the class i could write [code]...
I'm have trouble attaching graphics to the stage from a class. I can do it on the timeline but the code doesn't work in a package.[code]this doesn't seem to work even if I import the picture in the package.[code]
I am building a simple ToolTip-Class. In case the cursor gets to close to the stage's border's I'd like it to flip accordingly, so it won't get cropped.
For this I'd like to compare the stage width and my mouseX and then scale and wove things accordingly.
However when I try to get stage.stageWidth from inside my package it will return null.
I have a .as file with a load of functions that i include using : include "myFunctions.as".They can be accessed alright.I have a custom class that extends movieclip, and i want to use a function inside that class that is located in my "myFunctions.as" file.How do i do that? Seems like the class loads before the myFunctions.as file so the functions are unavailable at this time. I get that error message :
The attached SlideshowExample.as file works quite nice when I use it on stage directly. But when I tried to use it in Gallery_mc movie clip, it doesn't work
I have a MovieClip that I want the user to be able to drag inside the stage, but I don't want it to be able to move outside the stage. Currently I'm using this._parent.startDrag(); to allow the MC to be dragged, but I don't know how to stop it from being dragged outside the frame.
I was wondering if it's possible to change the frame of a movieclip (present on the stage) by going on a certain frame or clicking a button in the main movie, if you get what I mean. Let's just say I want to go to frame 2 in movieclip "Symbol". Also, would it be possible to do the opposite and go to a frame in the main movie from a movieclip?
I'm just starting with as3 object oriented programming -- i've always liked the idea, but could never "see" how the whole objects/classes worked with actual game development.in my fla file i have this...
Actionscript Code:
var moveBob:MoveMan =new MoveMan()
in my MoveMan.as file...
Actionscript Code: package { public class MoveMan { public function MoveMan() { bob.x = 5 } }}
and on the stage i have a movieclip with the name set as "bob" If i use this line in my fla file... bob.x = 100 it works.But when i try to move the movieclip inside the class i get this.1120: Access of undefined property
i'm trying to use compiled assets and code from a swc. Inside a new fla I select the swc to be included when exporting. When create the instance in the timeline of the code works and I can see assets that are inside the swc and trace a propertie from the same object. The problem is only when doing the same inside a movieclip, can't reach the assets (movieclip) but I can still trace properties from the class. I've uploaded the working files: master.fla is the one that creates the swc. template.fla is where I test the swc. files (This are cs4 .fla + .swc + .as)
I can't acces my MC that was created inside my class. 've got a MC "bttn" on my stage, if u create an instance of the BttnClass a copy of the MCbttn is made and given an other position, than I want to play the bttn's(contains multiple frames) and NOTHING happens. The Bttn's are copied,but I can't play them. So my class works but how can I play my buttons?
Class file: ActionScript Code: class Bttn { //variables private var num:Number //constructor function public function Bttn(i) { [Code] .....
I'm making a sidescroller for school and im trying to get my hit test working.
I'm having trouble because I'm not sure how to properly reference an movie clip that i added in my game engine (zombie_mc), to a seperate class for my bullets the code for adding my zombie to the stage
Quote:
if (zombieTime < zombieLimit) { //if time hasn't reached the limit, then just increment zombieTime++;
I have an animation (movieclipX) on frame 2 of main timeline. At the end of movieclipX I'd like the main timeline to move to the next frame, frame 3. How can I do this??Sorry if this is an easy question, I'm in the process of learning.
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 have a movieclip and within it is a bit of actionscript and a couple of different movieclips to make it function like the button on a ball point pen (you click it and it stays clicked until you click it again).
var booleanClick:Boolean = false; var colorTransform:ColorTransform = optBox.transform.colorTransform; optHitState.addEventListener(MouseEvent.CLICK, onClickHandler); function onClickHandler(myEvent:MouseEvent){
[Code].....
I don't want to get deeper into this monster of a project without making sure this is working first. Is my boolean working and just my trace statements aren't worded right or is my method to change the boolean wrong?

I have a movie clip symbol placed on the main timeline. The class linkage to that movie clip is Sheet. Inside Sheet class, I make a public string call _textRow. Inside the Sheet's constructor, I create a new TextField call values_txt. Inside the Sheet class again, I create a public function call updateTable().
The document class is Main. From the Main.as, I need to call updateTable() function to update the text inside values_txt. And I need to find a way to get to values_txt. That's where my problem lies.
Actionscript Code: package{//imported stuff herepublic class Sheet extends MovieClip{public var _textRow:String = " Lorem Lorem again";public function Sheet(){addEventListener(Event.ADDED_TO_STAGE, initSheet);}public function
[Code]....
Basically, I need to run Sheet's updateTable() from Main.as and update the values_txt.text with _textRow string. But I don't know value_txt's target path.
