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.
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';

When using LocalConnection that have two SWFs talking back and forth to each other. Are objects passed by value or reference?
View 2 RepliesI have this:
for (var i:int = 0; i < 3; i++) {
var newChoice:MainButton = new MainButton(function(){
trace(this["func" + i])} );
}

However, I get func3, which I assume is do to it finding the value of i. But shouldn't it pass by value since it's a number? How do I get the wanted result?
if i have multiple movieclips on the stage and i am writing a document class and in document class i import another class and i need to pass these movieclips to that class.
View 1 RepliesIs it possible to pass arguments "by reference" instead of "by value". I know it's possible in almost every programming/scripting language I came across until today, but I didn't find any hint for doing it in Actionscript For those who don't know what "by reference" means: If you want to pass a Number to a function, say
Code:
var mynumber:Number = 5;
calculate(mynumber);
and you change the value of the argument inside the function, e.g.
[code]....
then the call to calculate normally does NOT change the value of mynumber because you have passed mynumber "by value", which means the value of mynumber has been copied to the num argument. This means mynumber is 5 all the time.Now sometimes u want to be changing arguments given to a function inside the function, and this is where u will normally use references. Passing mynumber "by reference" would mean that after calling calculate the value of mynumber will be 6...I know complex Objects like MovieClips are passed by reference. But how to do it with simple DataTypes like Number, Boolean etc.?
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 know that in C# when you pass an object (non primitive) to a method the following is true: A reference to the object is passed Changes made to the object in the method are reflected outside of the method. Also, you can pass a reference to a reference in C# e.g this.changeObject(ref myObject);, in which case: Changes to the object and also to the ref are reflected outside of the method e.g. myObject = new new List(); would change the passed objects referred location. Is this possible to do in Flex/Actionscript - can a ref keyword be used?
View 1 RepliesI'm attempting to write a performance testing function that can take any function, run it X times and spit out how long it took that function to run in AS3. I've got it working just fine if a function doesn't take any parameters but it comes up with an error otherwise.Here's the code:

I loaded a SWF and passed the reference to a Class called Portfolio:

Now I keep getting one error or another. Right now, it's telling me:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I tried extending the thing but then I got a: "1203 No default constructor found in base class" error I just want to pass a simple MovieClip reference from one class to another.
It took me hours to figure our why this was returning the wrong value - when assigning one array to another it passes by reference not Value. I need a way to force it to pass by values. e.g. copy the existing array and have the second array reference it, so i am free to modify the first array without changing the values of the second.[code]From the example above You see that in Actionscript when assigning one variable to another it does it my reference not value. So when you chage the value of one array it changes the value of the other automatically.I need to have the "test2" variable reference the "test1" array only by value so if modify "test1" the values of "test2" won't be modified.
View 7 RepliesI'm trying to reference a movieclip that's been passed through the class primary function (constructor/instance, tried both) but can't get a button event instance to recognize it. Since the button's based around an event, I'm not sure how to pass the reference. I stripped a lot of the code, but left the function sctructure as the button events are tied into a dynamic loop structure, a main reason why I can't move the buttons to a different class.
The example looks something like this:
package {
import flash.display.*;
import flash.text.*;
import flash.utils.*;
import flash.events.*;
[Code] .....
I'm trying to figure out how to get the site_mc reference to the button event so it can trigger other nested movieclips inside it (gallery_mc, etc). If this were AS2 it'd be a piece of cake but now I have all these invisible walls for variable passing.
In a game me and a friend are creating, the levels are stored in MCs. In the level MCs there are several other MCs that the player should be able to interact with.
This means the objects in the levels need a stage reference. I can place all the objects manually and pass the stage ref in the constructor of the object's class, but this is a pain when the levels are going to be pretty big.
Is it possible to make sure that flash always passes a stage ref to the object even though it's not placed there by code?
I want to create a MovieClip, pass this MovieClip to a function in another class where it will be modified.The problem is, when I pass the MovieClip as a parameter to a function and start making changes, the changes are only made locally. The "copy" of the MovieClip inside the function gets changed, but the "real" MovieClip back in my main game class remains unchanged. Here's the code from my Main class:
Code:
var resourceLoader:ExternalResourceLoader = new ExternalResourceLoader();
var myMovieClip:MovieClip;[code].....
I have a flash file that has an XML driven menuing system to select and play various FLVs. I want to be able to craft different URLs to open the swf and start playing different FLVs. (The others will be accessible from the menu once the sfw is opened, but I am looking to control what plays on opening, dependent on what link a user click.) Not really sure about the best way to get the selection into the swf.

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?

I have several movies (movieA, movieB, movieC) that have a button in them that loads another movieb into the same level thus replacing them. My problem is that i need the movieB to start playing from a particular frame depending on which movie, a, b or c loaded it.
I'm trying to find a way of using variables to make it work or maybe just a simple gotoAndPlay function but with no luck. Can you send a variable via loadmovie function?
