Flash :: Reference Var From Frame On Timeline In An Object Class?
Jan 17, 2011
I'm using Flash Professional cs5/AS3 I'll try and describe this the best I can. I'm new to ActionScript. So, in my timeline I have a var on a frame that represents "lives" and i have some code in the timeline that takes down the number of lives depending on certain events, which all works great.
so, now i wanted to make a constructor class that I could reuse for a bunch of movie clip objects and I only want these objects to be able to move if the lives variable is greater than certain number. So now, building my constructor class for these objects i just wanted put an if statement that is looking to see if the lives are greater than a certain number, which if it is then should make these objects do what i want...But, when i run the project I get "1120: Access of undefined property lives."
lives is the var I made obviously like I said, and it works fine being referenced everyone else except when I make a new .as file for these objects then try and reference it. I get the same error when I try and establish "lives" in the main project class too. I'm not sure where I should put this var or how I can make it so i can reference it from an object class. I'm not really sure how to word or describe my issue which has made it hard to search for a tutorial.

Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:
stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)

So I have a MovieClip symbol created in the Flash IDE with a baseClass of flash.display.MovieClip and Class name of "Square". I have placed it on the timeline of my fla at frame 30 and given it an instance name of "square". How can I control that MovieClip from my DocumentClass? I have an ENTER_FRAME listener listening for the arrival of frame 30. At that time I want to simply do something to the "square" MovieClip. But I keep getting a compile-time error of "1119: Access of possibly undefined property square through a reference with static type flash.displayisplayObject.".

Is there a way to get an instance reference to the document class to call a method of it from the stage's timeline?I see that here's a possible solution: using a singletonOther solution I though of is using stage.getChildAt( 0 ) but it's not very nice.Is there an 'official' instance reference? because the document class is obviously instantiated at startup, but is that instance accessible in any way without having to use a custom solution like the ones mentioned?

I've been programming with AS2 for a few years and I just made the switch to AS3. I'm hoping there is an easy solution to this problem. I have a class 'Actor' (extends MovieClip) that needs to hitTestPoint on a nested MovieClip 'root.World.walls' in a function moveRight(). The line of code looks like this: ...while (MovieClip(root).World.walls.hitTestPoint(pnt.x, pnt.y, true)) {... But I keep getting various errors when I try different solutions.

The button on that frame (frame 50) is a new instance of the mainMenu button which was used on frame 1, but with new code (see below), which tells it to gotoAndStop on frame 2, but doesn't work. Any thoughts on this?

I'm trying to reference objects on the stage in the current frame from a document class in Actionscript 3 in Flash CS3. In this example, I'm trying to get at a dynamic text field with the instance name "question_txt", but there are also buttons and other things I'll need to get at to put event listeners on and such.
I have "Automatically Declare Stage Instances" checked in the publish settings, so the references should be there -- in fact, if I try to declare them in the class, I get errors about a conflict with the name -- but when I try to reference these objects (in any of several ways I've now tried!) I always get Null.

I'm building a game which makes use of a few extended classes. I've recently made a few changes in the way the graphics are ordered and am now running into problems, namely:
ReferenceError: Error #1069: Property grab not found on flash.display.Sprite and there is no default value.
at DraggableSprite/grabObject()
ReferenceError: Error #1069: Property drop not found on flash.display.Sprite and there is no default value.
at DraggableSprite/dropObject()
The general structure is as follows ('>' means extends) :
MovieClip > DraggableSprite > PlantPart > Seed or Flower.
DraggableSprite manages dragging/dropping objects with the mouse. It contains the offending lines of code being:
Code:
private function grabObject(evt:MouseEvent) {
trace("grabTarget: "+evt.target.name);
if (this._draggable) {
_origX = evt.target.x;
_origY = evt.target.y;
[Cde] .....
The Seed and Flower classes contain a public 'grab' and 'drop' function which manage some different effects of being picked up and dropped, but the code seems to stop short at the PlantPart class and register a sprite it contains as the 'evt.target'. I added this intermediate sprite to overcome a colission problem with the mouse. The sprite functions as a dragbox, while the Seed and Flower graphics offer visual feedback.

I have got a Swf file that contains only two frames, one has a timeline object called movie, the other doesn't. I place a trace(movie); statement in both the EnterFrame event listener and frame scripts on each frame and i found that the object movie is not available in EnterFrame event but can be accessed in the framescripts.[code]So I am just wondering when the timeline object is available during processing a frame and i can access the object? And from the output, it seems after the the SWF file being setup, there is no EnterFrame event dispatched for the very first frame, is that true?

I'm trying to go to the next frame in the main timeline from a class with no luck.
I have a movieclip called winner_mc that is created in the document class.
winner_mc is linked to the Winner class.
The Winner class creates a movieclip called nextlevel_mc which is linked to the Nextlevel class.
Then when I click on the nextlevel_mc movieclip I want to go to the next frame on the main timeline.
I tried this for the Nextlevel class:
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class Nextlevel extends MovieClip {

I am trying to code a flash app entirely in the document class. I am using GestureWorks with a touch screen. When a user essentially presses a button it calls a method that should hide a specific graphic but not the graphic they touched.
Essentially I need a way to refer to a graphic on the screen using a method besides 'e.target'.
I am receiving this error: Error #1009: Cannot access a property or method of a null object reference.
[Code]...
It can access photo1Sprite as 'e.target' when the button click happens on the photo1Sprite. The problem happens when to click one button (not photo1Sprite) and have it effect photo1Sprite. So I can make photo1Sprite react if my method is attached to it directly using 'e.target' but not if I am trying to call it from a method that was called from another element on the screen.

I followed the example from a previous question and I am loading an external swf using a loader and inside the loader event handler I am trying to cast the loader.content as my custom class PanelReferenceClip which extends MovieClip
When I publish I receive a this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Just to make sure and test that the swf location was correct and the swf was actually being loaded, I changed the type of the content to as MovieClip and it worked fine.
EDIT: I also wanted to add that these swfs are being stored locally and not being pulled across the internet, multiple networks or servers.
I am not sure if I did something quirky in my class so I am providing the source to my custom class PanelReferenceClip
package com.components
{
import com.UI.DevicePanel;
import flash.display.MovieClip;

I have the Dynamic Text field that has an instance name on a mid-timeline frame in Flash CS4. I have a class that inherits from Sprite, and which is always added to the stage on instantiation. How can I get a reference to my Dynamic Text instance from this class?
Example:
My Main class (linked in Flash's publish settings) goes like this:
protected function beginGame(e:MouseEvent){
gotoAndStop(8);
var game:GameContainer = new GameContainer(41,8);
addChild(game);
game.x=36;
game.y=128;
}
Game Container extends MovieClip, and draws some pretty gfx. On Frame 8, in the Flash IDE, there is a Dynamic Text element instance named "scoreText". I want to access this from the GameContainer class. Possible?

I've just started using classes while developing my basic platform game in Flash AS3.
On the stage I have a character, instance name 'ball_mc'. I have AS in the time line which controls the characters movements.
I have an external AS file named 'Ground.as' which is basically an ENTERFRAME hittest which stops the character from moving when the character 'hits' the ground.
I have placed a rectangle MC on the stage to represent the ground and linked it to the external AS file 'Ground.as'
The Code for Ground.as is as follows:
package
{
import flash.display.MovieClip;
import flash.events.Event;

I have a class, and I'm trying access an object outside of that class. For example, in my class I have function: onNodeLoad(node:Object)with that function I can access the properties of node just fine, but outside the class I cannot.In the function that is inside the class, I can trace (node. title)I want to be able to do that trace on the main timeline.[code]So right now, in my main timeline, trace(con.node) comes up null.I've tried to declaring _node public, private, public static.

I am doing a looping background with 2 identical BG movieClip (B1 and B2). Those 2 are "new" by the same class.
var B1:MovieClip = new BG();
var B2:MovieClip = new BG();
But because this BG class picture is loader from the internet and the picture is rather big. When I addressed its loading by using progressEvent. The picture is really loaded 2 times. Is there anyway I create B2 based on B1 without using new BG() again? Since it definitely makes a new BG with Loader code inside.

this is one of those upsurdly basic questions for which google does not work. I have usually dispatched events from my classes and dealt with the user interface in the document class. But now i want to separate all the UI in a separate class, accessible by other classes. have added it as a child to the main/document class, but how do i reference the main class without going through parent.parent shananigans?dit. one more thing i remembered. Some of my UI elements are not programatically added.here is the code i have. i get possibly undefined property error.

I've been trying to reference a Library symbol that is introduced in Frame 2 by using it's instance name, using timeline scripting only. I am trying to make a colour picker MC symbol for multiple re-use. Firstly I drew a small button on the stage and converted to MC, called textColourPicker of type CPicker (the class used to represent this MC in the Library). Inside this MC I have a button symbol called pickerButton
