I'm wondering if I should always use "===" (strict equality) when doing equality checks... Is there any example of when it is preferable to use "==" (non-strict equality)? In particular, should:
if (param1 == null || param1.length == 0)
be
if (param1 === null || param1.length === 0) ?
Im trying to create a 'simple' check statement for a textbox of type input. I used the following to check whether the user has entered something in the textbox
Code:
if(subject =="" || message =="")
{
trace("please enter something");
}
Simple eh ? well unfortunately if the user hits the space key in both these text boxes this statement validates false ! ..
What am I doing wrong !? lol, I even tried
Code:
if(subject ==null || message ==null)
{
trace("please enter something");
}
and i get same problem.
Got two numbers and need to check if they match up (same value).
this won't fire/doesn't work:
if(codeNumb == exCode){};
But this does work:
if ( (codeNumb + exCode)/2==codeNumb){}
What gives?
I'm testing the equality of an input textfield and a string variable. For some reason, it's always resolves to false even when the values it traces out are the same.[code]
View 1 RepliesI've been spending some of my spare time working a set of collections for ActionScript 3 but I've hit a pretty serious roadblock for the way ActionScript 3 handles equality checks inside Dictionary Objects. When you compare a key in a dictionary, ActionScript uses the === operator to perform the comparison, this has a bit of a nasty side effect whereby only references to the same instance will resolve true and not objects of equality. Here's what I mean:

Using php to declare a few Flashvars. No problems - they all arrive and behave. One of these populates a dynamic text field inside an MC. Simple enough stuff right? But.... when I try to test equality on that text field I get nothing. I've tried EVERYTHING I can think of. The MC is called "fake2". The text field inside it has a variable name of "choice_dyna" and an instance name of "fd2".

I'm working on a portfolio. Right now theres two buttons that both expand and close the box which contains my content. The only problem is once the box is expanded (viewing about me for example) and you clicked the contact me part, the box would just close and not re-open. So what I need to know how to do is to close the box and have it re-open with new content.This has to be done in actionscript because that was my challenge so please do not give me other solutions such as making more MovieClips,
View 5 RepliesI've made an external preloader (loader.swf) that loads another file (test.swf) - it works fine. However, if I change the test.swf-file with a new version, I have to clear my browsers cache to "update" the new version.
CTRL+F5 only seem to check for a new version of the loader.swf - i cannot force update the file which the loader checks for.
So to the question, is there an easy way to have the preloader check for a new version of the test.swf?
I would like to have menuItems with checks that show what element of the menu has been selected. I know it is possible to have checks with XML. But is it possible to have variables in XML because the elements of my menu are variables. If there is a component on sale that has exactly the design of the flash component menuBar + menu and that is more easy to program,
View 0 RepliesI was writing some stuff today and i realized that variables inside a class are not constrained to the constructor or method scope. In my opinion this is utter lazynes. Scopes need to be fully enforced to force programmers to comply with correct OOP styles and organization.
to force yourslef to comply with the standards, when reffering to the consturctor always use the 'this' prefix and use 'var' for all temporary variables that should be inside the method scope.

finishing a function that checks 6 positions (indiciesOfInterestShape) in a dynamically updated array (productCode) for two types of values; the number 0 or any number between 1 to 8 .I need the result of this function to update the finalNumber variable to a number between 0-6.If a 0 is found at any of the 6 indicies it will mean the final number does not increase.If a number between 1-8 is found at any of the 6 indicies then the final number increases by 1. And seeing as there are only 6 indicies to check the maximum number will only ever be 6.This is what I have so far
// indicies that are dynamically updated 10 19
public static var productCode:Array =
[C,A,1,A,1,A,A,1,A,A,0,0,A,0,0,A,0,0,A,0,0,A]

I have a MovieClip that when the update(); function is called, it checks the cells (on a grid) around it to see if there is an object there. If so it updates it's image to reflect that.

I am learning ActionScript 3.0. Coming from Java world I can easily relate to strict compilation mode. I think having type safety checks at compilation time makes perfect sense. This makes me wonder, why the compiler allows a standard mode were all the type safety checks are deferred to run time? Is compatibility with older ActionScript specification the sole reason for having standard mode?

I'm trying to get a custom flash gallery going by using the loadMovie command with Jpeg's. I must use this method as it's what is required by our project. I am trying to figure out some way to make an array to keep all of my image names and then detect which button is being pressed and have it call the corresponding number within the array.Currently I have some code that is working quite well but not fully

stop();
var thumbArray:Array = ["i1", "i2", "i3", "i4", "i5"];[code]........
I have two buttons currently instanced named i1 and i2.The trace is working and calling "i1" but for some reason even though i set i1 = "thejpeg.jpg" it isn't calling the jpeg.I can upload my file if necessary.Also i'm going to need to be able to unload the opened jpeg by clicking anywhere off of the jpeg's area, .i know how to unload a jpeg but I don't know how to detect when you click any surrounding area of it.
In flash, is it possible to have your application check that the environment it is running on is "recognized". If so, how do you go about doing it? I want to put my swf on my website and prevent people using it on their site.

I'm struggling with the transition to AS3, specifically not being able to use parent like I used to. Aside from it making me a better coder, are there any good reasons to use strict mode? If I dont use it, are there any 'side effects' to my swf I should be aware of? Any input on parent and strict mode.

I need to create a custom Object that basically stores some custom parameters (properties?), which I have successfully done, and the code below works fine.
PHP Code:
myObject = new Object();
myObject.nameLabel = "New Releases";
myObject.artOrientation = "portrait";
myObject.artAmount = 5;
I find the new compiler and debugger capabilities very useful, since I'm not the most detail-oriented, so I (usually) like that Flash forces me to strict-type my variables and such. Anyway, I was wondering if it's a "best practice" to strict data type a custom objects' properties, and if so, how to do it in the logic above? I kept getting syntax errors when I just tried it initially.
I know if I created a custom Class .AS file, I would be forced to data type the properties... but I'd rather just do it "in-line" in my main .FLA file. Also, I know I can just pass typed VARIABLES to the properties... but I'd rather have the properties strict-typed themselves... so if I try to pass a variable as the wrong type, then I would still get an error.
I'm looking for will all happen in about two or three seconds. I'm re-building my own website using AS3 package classes. When the API loads I want everything to appear in sequence from invisible to visible. First the logo, a few lines drawing themselves, then all the navigation buttons at the top appearing in a quick-fire horizontal row, then the content rolls in, etc. I want strict, accurate control over about two or three seconds, of how and when everything on stage goes from invisible to visible in a quick-fire sequence. I know it can all be done with several timers for each alpha going from 0 to 1. But can all the variables going from alpha 0 to 1 be bundled into an Array? And the Array fired by ONLY ONE Timer using a For Loop? Or am I just barking up the wrong tree? Should I just use a bunch of Timers? I want to avoid a Tween because I want very accurate control of the quick-fire invisible to visible effect. And I want it to be easy to change later. Can this effect be done by ONLY ONE Timer rather than several Timers? And if it can, how do I make the timer fire all variables in strict sequence? Do I use an Array with a For Loop? Or something else? I've been looking for a couple of days but still haven't found anything close.

View 2 RepliesI am following a code example in a book and have the final fla and as files, so I know the project works when fully coded.In the book, it tells me I can test the movie to make sure that it is working so far. When I do that, I get the error 1120: Access of undefined property.
The "property" is a component instance. If I take the example completed code and remove everything up to the point I am at, I receive the same errors, so I know it's not a spelling/syntax mistake.I have a feeling it is the Compiler in Strict Mode. But, when I change it to Standard Mode, then I get error 5001: The name of package 'com.foundastionAS3.ch12' does not reflect the location of this file. etc.
note:: attached is a file of the compiler when it gives me multiple 1120s.
I have a BUNCH of bumpers of four types bounceUp, bounceDown, bounceLeft, bounceRight. during a collision which you hit determines the bounce so they always do the same thing so here's my question.....can i just name every bounceUp instance the same thing and then just add that one instance name to the list the collision detector checks?
i just dont wanna go through and name a hundred each of bounceUp s and bounceDown s individually as the potential for screaming increases proportionally.......
