What is the difference between declaring a variable like this: variable = 1; and declaring it like this: var variable:Number = 1? Why is it better to use the second way?

whats the correct syntax for declaring a variable thats name changes according to a different variable.
What I want to achieve is pretty basic: I have an input text with instance name (contact_date) and I want the information the user enter in this input field to be kept in a variable that I can reuse later on in my movie.

View 2 RepliesI have several movieclips that I exported to actionscript from the library (c01,c02,c03,...)In the actions I have a conditional that checks a variable and depending on the variable provided I want to create a new instance of that movieclip. For example if cityY==1 then I want to create a new c01.
I tried with conditional and with a switch/case but I get an error declaring the newCity variable more than once.[code]...
Im using a tween engine, and its syntax for use is as follows::
[Code].....
How can I write "_x",100,1,"easeout",0,callback as a string?? I have tried to put "these" around the text. The problem seems to be that "_x" and "easeout" which are effectively strings inside the string! -- but for the tween engine to work - I need to declare that.
I'm trying to find information in how or if it it possible to declare a Variable Type that can accomodate 1 of 2 different Types In this particular case I'd like to set a Variable able to accept either Integrals or Strings I know i Can use a wildcard as below and it works, but it also allows for any other type to be added.
private var _destination:*;
My first Thought was something like this
private var _destination:String^int;
private var _destination:String|int;
Unfortunatly this does not work
I'm trying to create a unique variable and reference to it with myRewind for some button functions.
I'm trying to create this rewind+variable as the unique identifier but it just seems to be using myRewind as the variable and overwriting it.

View 1 RepliesI am trying to send a value from one of my xml nodes (<marker>) by declaring it in a function 'showData' as a variable 'XMLMarker'. If I trace this value (XMLmarker) it returns the right data found in the node <marker> (which is 'myMarker_mc'). However, I need to tell the stage that myMarker_mc is a MovieClip...please see the 'PROBLEM' stated in the code below.

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.

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.
Whats the difference between a variable and a function? Ive started reading an actionscript book.....and to me it seems there the same.
View 4 Repliesi want to access variables from within movie clips, and my question is, when declaring variables from the root, is it necessary to add the _root? e.g.:
Code: var _root.imgSource:String = "img001.jpg"; or would it be sufficient to declare the variable in the root timeline, then refer to it in child clips as _root.imgSource?
I want to create a vector, then call a function that populates that vector with arrays. Fine. The only catch is the function itself will declare new array variables to put into the vector, but are these new array variables private to the function only?e.g. something like this

public var vec:Vector.<Array> = new Vector.<Array>();
private function populateVec():void {

I would like to know what's the difference when I write a temporary variable like this (these are just examples): version1
[Code]...
What's wrong and right? Currently I write it like version 2 and I'm not sure if I should change it to version 1. I know most developers write like version 1 but I'm a little bit confused because I am totally unaware about version 1. If I use version 1 does that mean that my value is stored explicitly in a temporary variable that is cleared in every cycle?
Should I declare the _mcContainer var before the loop or no? (performance increase?)

I have a simple math game where the user enters his answer and clicks a button. The problem I am having is that if the answer is wrong, the numbers in the question do not change on the screen but but in the actionscript, the variables being used to check the answer change. How do I get the variables to stay the same when the user's answer is wrong? Not redeclare all of the variables.
Code:
var num1:uint = Math.Random()*1000;
var num2:uint = Math.Random()*1000;
var sum1:uint = num1 + num2;

I want to declare on multiple numerated variables like this:
var myVar1;
var myVar2;
But I don't want to do this manually for every variable instance but automatically, so I need a way to instruct the compiler to declare by himself on every variable and to numerate them automatically.
So hopefully I explained myself well, I wanted to know if there is such way to do this?
If you declare an instance of an object with out assigning it a variable, does it stay in memory or does flash automatically garbage collect it? For example if I just keep using new Date().getTime() to update a persons time from his/her system clock with out assigning it a variable will instances of Date() objects just keep piling up in memory or is it ok to do this?
