ActionScript 3.0 :: Reference A Object Through A Variable?
Mar 11, 2010
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 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;
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.
Basically 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?
I have problem with accessing object created by function imported from another package. I have 2 packages DragDrop and UserInterface. In UserInterface I create methods for buttons and later add them in DragDrop . I make it in two different ways: One(this one works):
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"
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.
Code: var Make:LoadVars = new LoadVars(); Make.onLoad = function() { VARIABLE = Make.textVariable;
The scene is a number of movie clips, all already added to the stage (i.e. not dynamically) and when one is clicked, I need to call a property of that clip. [code]...
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]...
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?
Is there, uh, a way to use the value of a string to reference a variable name?
I'm trying to dynamically assign XML node names and attributes using a string value, I tried something like this:
Code: var sItem:String = "book"; // to be dynamically assigned for (var i:uint; i < _xml.book.length(); i++) { aList.push(_xml.(this[sItem])[i].@title);

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.
