I desperately hoping someone can shed light on my problem. I am trying to reference a movieclip with a variable. I've done it before but in loops reading from xmlobjects but cannot get it to work in the most simplist way....??ar i = 0;_root.movie[i]._visible=0;
View 2 RepliesIs it possible to reference an object using a variable value?
For example, I have a function that is supposed to hide an image and add that image to an inventory list when the item is clicked.
All the image info is stored in an object (name, imgSource, visible, x, y);
I was thinking I could do something like this:
<fx:Script>
<![CDATA[
public var item:Object = new Object();
[Code].....
I want "item" to stand for knife so that I could change knife.visible, knife.xPos, ect.
If I wanted to change the 'x' of a object, and a variable contained a the object's name, how would I change the 'x' by using the variable.Without variable:
Code:
myObject.x = 123;
With variable maybe?:[code]....
i'm referencing variable names and object names dynamically such as:[code]i have 5 balls (insert joke here) which get all the same functions etc so i wanted a way to avoid making 5x functions to handle each one of the balls. Now one function can handle all 5, etc.what i can't figure out is how to use this same set up to reference a variable or object name inside another movieclip. if i have another movieclip named "myParent" for example, i thought i could refer to it with:[code]but this doesn't work.
View 5 RepliesBasically I have 2 classes, A and B. B derives from A. Inside A, I declare a static variable/constant to the class of B. When I run the program, I get a null object reference error, with the line pointing to the class declaration of B, i.e.
Code:
public class B extends A
For reference, these are the 2 classes:
Code:
package
{
public class A
{
[code]...
Also, this error only occurs when the variable is static. If it's just a normal variable it works fine, i.e.
Code:
private var OTHER:Class = B;
If I change the static variable to point to a different class, it's also fine, i.e.
Code:
private static var OTHER:Class = Main;
I can probably work around this, but it's a bit of a pain in the ass. Anybody know what's causing it, or is this a Flash bug?
How do I reference the variable pointed to by the variable text but pointed to by more than one function?Say I have:
engine_level = 5;
tank_level = 3;
v_name = 'engine';
[code].....
How do I reference the variable pointed to by the variable text?
Say I have:
engine_level = 5;
v_name = 'engine';
pb_name = v_name + '_p_button'; // so pb_name = 'engine_p_button';
level = v_name + '_level'; // so level = 'engine_level';

I want to be able to reference the text of a text box within an MCThe MC is called "box1", the text field is called "field1"...I have many MCs (all with field1 in them)... box1, box2, box3 etc etcObviously I can set the text to being something by saying...box1.field1.text = "set_this_text"However, I'm using a variable to come up with the "box1" bit. (Using an array and a loop to figure out which box I want to update based on where the user clicked). So, let's say I have a variable... and I want to say..boxClickedon = box1 //will be defined by userSo I don't know in advance about box1... I can only access it through "boxClickedin" variable, but
boxClickedin.field1.text = "set_this_text"
or
[boxClickedin].field1.text = "set_this_text"

Is there a way to reference a function via a variable? In other words, instead of saying something like:
var theVar = someString + 'function';
if (theVar == 'functionName') functionName ();
to access it directly:
(someString + 'function') ();
using some kind of bracket notation?
Using AS2. I have a variable defined:
activenav = "services";
I then want to reference the variable in a MC string. I've tried many variations of this:
_root.my[activenav]Clip.gotoAndPlay("Out");
Essentially, I want Flash to see this as:
_root.myservicesClip.gotoAndPlay("Out");

i have a function that read a variable from a text file, yet i can only read the variable from within the function. How could i create a global variable or such that i can then read from outside of the function.

Can you have "ByRef" arguments in AS3 functions?
Primitive types in AS3 pass by value instead of reference. Is there a way to override that behavior and pass by reference for certain variables? [code]...
Code:
public function Text1Down(e: MouseEvent): void{
var textArea:Label=Label(e.currentTarget.id);

I get this error:
Code:
TypeError: Error #1034: Type Coercion failed: cannot convert "text1Area" to mx.controls.Label.
I know that e.currentTarget.id is of type Label. All I want is to make a reference variable so I don't have to keep typing long names.
I'm writing a function which can take the names of different variables and use them to do some calculations. Long story short, I want to be able to call the function like this:
It probably seems like a really roundabout way to pass the variable through its name rather than just passing the variable itself. This is related to me using XML to get the variable names, so they come in as strings. Just bear with me here.
Inside the function, I want to be able to do something like this:
which should then trace the variable's value. Unfortunately, I just get an 'undefined'. How do I use 'this[]' to get the value of the variable from a string corresponding to the variable's name?
I'm not entirely sure that I've even asked the question correctly in the title but hopefully) this description will make it a little more clear.

private var mySpriteA:Sprite;
private var mySpriteB:Sprite;

function foo(bar:Number){
bar = 5;

simple example. How do I pass bar by reference to change it's value in the function.
well at least in C++ it's called passing a variable by reference.
Is there, uh, a way to use the value of a string to reference a variable name?

View 1 RepliesLets say I have 3 Movie Clip Symbols in my Library : Movie0, Movie1 and Movie2
Each movie has a dynamic text box: "TextBox1"
I want to be able to write a function that can manipulate the alpha(or any attribute) of the TextBox1 in all three MovieClips.
In my limited experience I thought I could do something like the following:
for (var row:int = 0; row < dataArray.length; row++)
{
Movie(row).TextBox1.alpha = 1;
}
I hoped that this would loop through 3 times and set the alpha of the TextBox1 in all three movies to 1.

I have 10 text fields named "text1", "text2" etc;
I'd like to use a for loop to pulate each one, so that each text filed is populated with whatever i is:
for (var i:Number=1; i<=10;i++) {
"team"+i.text = i;
}
I keep getting errors with regards to how the text filed name is referenced.
What is the correct way to increment the text filed name and reference it?
I've tried:
["team"+i].text = i;
"team"[i].text = i;
but they don't work.
I'm creating a dynamic movieclip and the name/instance name is stored in a variable. How can I reference the instance if its stored in a variable?This is what I'm using and it doesnt seem to work (for obvious reasons). I know in php that you do this "blah blah" . $variable.
