I have a custom class which uses some buttons on the stage. Or at least is trying to.say have this code in the customClass.as file
package{
import flash.events.*;
import flash.display.MovieClip
[code].....
i have 3 check box's and input text fields on stage that i would like to null out using the reset button however i seem to be targeting the objects incorrectly as i am getting this error:
Error #1009: Cannot access a property or method of a null object reference.
Code:
package
{
import flash.display.*;
import flash.events.MouseEvent;
[Code].....
this is the code and the movieclips are target1_mc & target2_mc
package { import flash.display.MovieClip; import flash.events.MouseEvent; import flash.text.TextField;
public class recipeMC extends MovieClip {

I am making dynamic drag and drop game.I have a class for the dragged items containing the drag drop code.My problem is I can't call/access the movie clips I've already put on the stage in my hit test statement.Here is my code and target1_mc & target2_mc are the existing movie clips on the stage:
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
[code]......
me only still learning as3, i've checked google there and back, but somehow i can't find the answer for this: how to target a movieclip instance which is already on the stage from within a class file? i mean, targeting it from the document class file is easy, but what is i want to target it from another class file?
View 2 RepliesOk. So heres what I am trying to do. I want one movie clip to follow another one that I move around with actions on the main timeline.The problem is that the follower clip is linked to a class file and I cannot find a way to find the players position.

I have created a class, call it Class1, that has various objects drawn on the stage (drawn in the IDE). It also has a function, called setColour, for changing the colour of those objects. The function works fine if I call it from within Class1.
Now I have another class, call it testClass1, that imports Class1 and calls the setColour function. First of all, none of the stage objects from Class1 are visible. Secondly, when setColour tries to modify the colour of an object, I get the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
This is the code for testClass1:
ActionScript Code:
package
{
import flash.display.*;
[Code].....
So, what is the problem? Is it possible to change objects that are drawn on the stage of an imported class?
The following is that long only because I gave examples of what I want to know, not because it is complex .I have three basic questions regarding AS 3.0 classes.
1. How can I make a class object interact with an object on stage?
For example, when I have a square (mc_Square) with class "square" attached to it and I want it to trace "Colliding!" and print the X and Y of the mc_Box on contact with an on-stage *hollow* box (mc_Box) that has no class attached to it.how to do it vice-versa would also be awesome .
2. How can I make a class object interact with the same class object? For example, when I have two squares (mc_Square) that both have the class "square" attached to it and when they collide, it prints the X and Y of both of them.
3. How can I make a class object interact with a different class object?
For example, when I have two squares mc_Square1 with class "square1 (that also has a variable Primary=true written in it)" and a mc_Square2 with class "square2"; When they collide, the one with Primary=true would be removed and it's X,Y position traced.
How you can assign a class to an object on stage.[code]...
This would make a new object, but the current object already exists, it just needs to be notified that it's of the type "ClassName" so it can inherit it's properties.I've also tried assigning the "ClassName" in the linkage as either the base path or the class name. But in either situations I get an error saying that the class needs to be unique when I use the same class on multiple objects.
I have a document class called Main, and a class called DispatchEventExample. In DispatchEventExample, I'm trying to add an event listener to the stage but get an 1120 error, access of undefined property stage.
If I understand things correctly, even though I create an instance of DispatchEventExample in Main, it's not added to the display list & therefore cannot access stage.

Linking class with stage object..
View 14 RepliesI have a class that have a method to do some work and return a MovieClip. How can I access the stage from the class ? I don't add the class object to stage.
My code is like this :
Code:
import com.ClassName
.
.
.
var c:ClassName= new ClassName();
var mc:MovieClip;
mc = ClassName.create("some parameter");
I want to get access to the stage from ClassName class file.
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've googled this to no avail, I've only found how to manipulate the stage itself and not a display object on it,I have a movie clip on the main timeline with instance name displayName. I created a button that should change what frame displayName goes to (in order to...did you guess it?! diplay the Name of the button.So I am trying to write the code in a reusable fashion and have the buttons all linked to a class called GeoPuzzle. Inside GeoPuzzle I instantiate a touch event and run the code. However, the function has to be able to change displayName in the main part of the timeline and, of course, the compiler says displayName doesn't exist because I'm in a class and I'm talking about the stage.[code]How can I tell displayName to change it's current frame from within display object class?

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 was wondering if there is a simple way to access variables from a class object, where the variables are not actually a part of that class. So if you had an array defined on the first frame of the stage, and added some elements to it, you could use the methods of the custom class to manipulate the array's data.
Stage Frame 1
Code:
var myArray:Array = new Array( "apple", "banana", "pear" );
var myClass:someFunctions = new someFunctions();
myClass.addValue( "orange" );
myClass.sortValues();
[Code] .....
It might not seem logical as to why you would ever want to do that, but it's a very simple example, and it's the means I'm after, not the result. I'm creating a list of functions available to execute by a user via an input field. To keep things simple I made them the methods of a class. The issue, however, is that these methods need to manipulate objects which are on the stage, added and removed by a separate controller class. Passing the objects by reference to the class as a parameter would not be viable with what I'm trying to do either.
I have a dynamic textfield called neighName on my Flash stage. I also have a movieclip that I call a region on my stage. When I mouseover the region, I want a word to display in a little popup *and* I want some text to display in my textfield. I have an external .as file for handling the region. I can make the code "see" my region, but I can't seem to make it see my textfield, although no errors are being thrown.
View 1 RepliesIs there a way to make an static method act over an object of its class that is already on the stage, without using the keyword "this"? I mean, like "generic object of this class: do what I'm telling you to do, wathever your instance name".My goal is to create an method that get called by any object of this class, based on the changing on the value of an external variable, but since I cannot use the "this" keyword to reffer to each instance, I could not figure out a solution.

I have a class called shapeC that only creates a rectangle and then addChild(rectangle);. That class is instantiated on the main timeline. Currently, the only way you can see that rectangle is to add the instantiated class to the stage via addChild(shapeC);. My question is, is there a way that the shapeC class can add the rectangle to the root stage without requireing the instantiated class to be added to the stage?

I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

I'm creating an interactive time line, which for our purposes now will consist of flags and poles. The flags will just contain information like "December 2004" for example. The flag MC has a linkage name of ABFlag, and for each instance of it dragged onto the stage, the pole is dynamically drawn.The problem that I'm having is that I would like to be able to target all instances of the flag that are on the stage from an external class (not the document class), and I don't want to add instance names to all the flags. Is there any way that I can target movieclips that are on the stage using their linkage name instead of naking instance names? I do not have the option of placing these flags on the stage dynamically.
