View 12 RepliesFirstly, I've created a global variable called mc to store a movieclip instance:[code]Later on inside a function, I've created a new instance of my movieclip and added it to the stage.[code]Now, this is working fine most of the time. But at one particular point in my program, after many other things have happened, when trying to remove this movieclip it throws the 'display object must be a child of the caller' error.So, I'm thinking if mc isn't a child of the stage, what is it a child of? Tracing mc.parent returns null - so it seems to be telling me that the parent (which was definitely the stage when it was created) has wandered of somewhere and abandoned my movieclip!I have no idea how this has happened, and as the whole program is several thousand lines long I can't post it here. So, does anyone have any idea what might cause a display object which is added to the stage to become orphaned like this?
View 1 RepliesI have a data grid in one frame, then upon moving to the next frame use removeChild to get rid of it, which works fine.But it seems to leave behind the keyDown handler that is naturally part of the component (which is used to navigate the rows of the datagrid).Is there any way to get rid of this?The first time (and only the first time) I press the up or down arrow key in the next frame which does not have the grid, I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

I've got a Vector of ViewToActionMap objects, which have following constructor:

I'm trying to get this one function to be able to call many functions (not at once, but call many possible ones)In other words, I'm trying to get this variable to be named as a function. That way, this one variable can create multiple functions.example:
actionscript Code:
class Thing extends MovieClip{ var funcvar; var othervar; function onLoad() funcvar = "YYY"; othervar = "ZZZ"; function onEnterFrame()
[code].....
is it possible to write a function to move an object and then call that function on a clip event for instance
function (bounce){
script;
script;
}
and then call it by saying
on(mouseOver){
this.bounce;
}
is it possible to store a list of params needed for a function in an array and then use that in a funciton call?
[Code]...
or something like that?? Prob have to iterate the array but how do i get the params into the function call? Is this even possible?
How do I execute callback functions dynamically by passing a function in as an argument to another function?
Look at this example:
Code:
package {
public class myClass extends MovieClip {
public function myClass(callback) {

I have a set of Cue Points in an FLV I'm playing. It's an interactive quiz, so the idea is that flash will change a variable, theAnswer, to a different letter depending on which question it is. The answer to question 1 is B, question 2 is D, etc. Either the cue point event listener isn't working, or else it is working and Flash isn't declaring the variables. 1120: Access of undefined property theAnswer. I literally can't find a single problem with my code. I have an almost identical Event Listener further down which works.

I need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards.
The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?
Let's say I have a Custom Event Class, and it has several Event types stored in static Constant:
[Code]...
Is there an easy way to validate that the type passed to the Constructor is one of the Static Constants of the Class, without having to check it against each value?
is it possible to declare function this way
ActionScript Code:
function startShake(e:MouseEvent, num1, num2):void
what i mean is it possible to send to the function not only en event but also a variable and a second question how can i access
ActionScript Code:
function stopShake(e:MouseEvent):Array
this array that function return.
How create baseurl function in flash and how i call that function in button script

Is it possible to call a function and fill in the parameters based on an array and it's length?
is there a way to refer to all movie clips on the stage or apply a function to all movie clips without applying the function to all manually?

This runs contrary to my understanding of the pre-compiler and code execution order. In my way of thinking, any reference creation and related memory allocation is made when the object is instantiated, and indeed that allocation, unlike C depends not on code order (declaration before use), though this is an order that would satisfy even the C pre-compiler. If I understand the Flash compiler at all, it's not even a question of 'code order'... the symbol is pre-compiled such that for it to exist... for it to be instantiated, the variable would exist before the function would even be 'available' to be called internally or externally. Is my thinking way off, or is this a bug?
I have an AS3 program that calls a function multiple times. The function must return multiple variables, so I created a class for the function to declare an object containing all of these variables. For example, here's my class:
package
{
public class PER
{
[Code].....
Let's say the calling program calls the function, which returns the variables into data_set1 (where data_set1 depends on input variables arg1, arg2, arg3) using:
var data_set1:PER = function_name(arg1, arg2, arg3);
The calling program does some stuff, then calls the function again, but returns the variables into a new variable name, data_set2:
var data_set2:PER = function_name(arg4, arg5, arg6);
My intention is that data_set1 and data_set2 are different (e.g. not linked together).
My question is, given that arrays are passed by reference, will data_set1 be modified to agree with data_set2 upon the 2nd function call? Why or why not?
I'm doing a basic site with frame labels on the main timeline whose name corresponds to the btn names. A simple otoAndPlay(evt.target.name); I have a basic navigation setup of 7 mcs with mouse eventlisteners for CLICK, ROLL_OVER and ROLL_OUT.
Example:
prepare.addEventListener(MouseEvent.CLICK, navigate);plans.addEventListener(MouseEvent.CLICK, navigate);retire.addEventListener(MouseEvent.CLICK,
[Code]....
Does anyone know a better way to do this so when my mcs are clicked they display the rollover content/art? In essence I'm trying to achieve that when the user clicks a btn it goes to that "page" and the corresponding btn stays highlighted. Pretty standard web navigation technique but I just don't know what the best way to do this in flash is and with how my site is setup.

I am working with AS3 to build a very simple mp3 player on my site. So far the play and pause button work fine, but when I try to move the slider then click the pause button, it doesn't pause, and then clicking the play button again causes it to play a new file.I'm assuming that for some reason when I call the playMp3 function from my MouseEvent, it's within an object or something and not at the root, so it's like loading a new sound file, but I don't know how to fix that.URL...

I'm trying to find a function that will repeat my Rotational tween function. I found the yoyo() function to be what i want to do but i don't want the tween to change the rotation to CCW while originally moving CW. Basically i want the animation to move CW at a steady rate continuously.
I'm using the following code at the moment, i'm not too sure if this is the most suitable code for this situation, maybe im off track.
From my thoughts, i assumed that i would need to put the stars function in a onEnterFrame to repeat the animation and change yoyo() to continueTo() function. or maybe some sort of if statement in the stars function?
ActionScript Code:
import mx.transitions.Tween;
import mx.transitions.easing.*;
var stars:Tween = new Tween(ring, "_rotation", Regular.easeInOut, 0, 360, 4, true);

I had a function that occured on mouseclick called go_out. I want this function to occur when the timer fires after 5 seconds. After the 5 secons I receive this error:

I am currently trying my 5. workaround to get my menu done. . I want to move a series of 4 buttons up, after a click and when all buttons finished their movement I want the bottom 3 to move down again.
My big problem ist, that I dont get a check working to see if the function move() hast finished in order to fire the function open(). Is there any listener or so?
Here is my code:
Code:
//Setup and register with Zego Engine
import com.mosesSupposes.fuse.*;

The generally used workaround for this, is to use a regular function instead of a getter/setter. This results in having to have ( ) after the function variable obviously. The question is, can a Function variable be assigned to a getter/setter function and retain its attribute of not needing brackets.
Below is some Pseudo code representing the question:
#########################################################
public class Foo(){
private var prop:Object;
public function get Prop():Object{return prop;}

I'm having some trouble passing parameters with a function that is itself being passed as a parameter.In my application code I'm instancing that class five times:they are buttons in a menu.In that class, I've got an onRelease handler that does a number of things when a button is released, one of which is to invoke a function that is defined in the application level of the code.My problem is that I don't know how to send the function parameters.In my StandardButton class I have:
class StandardButton extends MovieClip
{
/* define properties */[code]..........
The function is successfully being "sent" to the StandardButton class, but without any parameters.How can I send parameters to the class instance with the way I've got this architected.
i have a function that receives a function as a parameter. example:
function foo(bar:Function):void() {};
how can i set a default value for the function to be an empty function so the user will not have to paste a function as a parameter ?
I have 2 functions, 1 loaded before another. Some value are determine by the other function data, but since one of it has to load before the other 1, how should I get the data that is loaded after current function?
private function wMessage():void {
Message.width=Name.width+20;
}
[Code]....
I've taken out some other unnecessary codes, but as you can see Name position is set according by the position + width of Message, but I want Message's width to be not smaller than Name
I have a situation where, upon loading my swf, I add an event listener to the stage to listen for keyboard commands. One of them is to listen for the spacebar, and if it is pressed, it should play a movie. The problem is, that movie is not loaded until later on, depending other user interactions, therefore, until it is loaded, the reference to it would be undefined.
But if I wait and add the listener for key commands only when the movie is loaded, then I can't utilize the listener for other keyboard commands, like RIGHT or LEFT, which are the buttons which get you to the movie in the first place. Is there a way to add a conditional or something to prevent that code from being executed if the video is not defined yet? Here's my code:
