View 2 RepliesActionScript 3 :: Define Variable From Its Creator On Stage
Jul 3, 2010I am trying to split up my code in classes. But there is a issue what really bothers me. When I create a class for functions I am giving its own stage. Like this:
dragf:Dragfunctions = new Dragfunctions(this)
And in the class i use this
var stage:Object;
public function Dragfunctions(stage:Object) {
this.stage = stage;
}
As you can see I can now call a variable of the stage using stage.var1 = "hi" but when I need to adjust that variable many times it gets a quite messy. There is a way to tell that when I call var1 he knows i mean stage.var1 without need to call stage.
Its:
var var1 = stage.var1
And then using
stage.var1 = var1
But that is quite unhandy too is there a better way?
ActionScript 3.0 :: Using String To Define Function And Variable (?)
Nov 16, 2011I'm trying to make children of a tile and put them in their respective locations. To do that, I need to know what kind of tile is to be created, but if I just use my old method:[code]I will have to use a chunk of code like this for every single imaginable tile. Obviously, that is not efficient! So I'm trying to optimize it by having what tile type is to be posted saved in a string, then using the string to refer to what child is to be created, something like below:[code]how to make the above code work. Surely, there is a way to do this?

Flash :: Static Variable Showing As Null
Feb 13, 2012I have a class named Locator that I use to GeoLocate a user. There's a static method in that class called "locate()". This method then calls another method which sets a static variable called "loc" to an instance of a LngLat class.The issue I'm having is, when I call the locate method at Frame 1 on the scene, and then try to access the loc variable it shows as null... but when I trace the loc variable after it's set in the Locator class it shows as an object.[code]and then trace the variable at the end of the static method in the Locator class it shows as a object and the city is traced as expected.

ActionScript 3.0 :: Parameter Child Must Be Non Null - Variable Scope?
May 5, 2009I'm working on a sliding gallery like Hulu. Setting it up and the sliding slides in and out is working fine. However, I need to add and then remove a button to each slide as it comes in and goes out. (I initially tried including the button on each slide, a mc, but this proved problematic for the event listeners). So when the file loads up, I add a mc to the first slide of the group like so (features[] is an array of movie clips - my slides):
Code:
var goBtn:MovieClip = new FeatureButton();
features[0].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
So I add the button/mc to the first slide - works just fine.
So there are two handlers, next and previous. So I started with the next handler. The first thing I have to do is kill the button on the panel that is sliding out, so I do that like so:
Code:
features[featureCount].removeChild(goBtn);
goBtn = null;
(featureCount is a counter keeping track of the slides). This works fine. I click the next button, and the button on the slide disappears and we move to the next slide - perfect.
So then I add the following next - exactly like I did in the beginning:
Code:
var goBtn:MovieClip = new FeatureButton();
features[featureCount].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
This time adding it to the current slide coming in - but this generates the following error:
Code:
TypeError: Error #2007: Parameter child must be non-null.
at flash.display::DisplayObjectContainer/removeChild()
at featuregallery_fla::MainTimeline/nextFeature()
How I'm getting an error on the removeChild() when that is already gone. I assume "parameter child" means goBtn - yes it is null because it's been removed. But I'm not trying to do something with that. I can only guess this is a variable scoping issue with goBtn - but I'm not seeing how to resolve it. Flash file attached.

Arrays :: Accessing Variable From Other Class Returns Null
May 10, 2011I did a separate levelData class to be able to flexibly add levels. I was happy with it until my supervisor ordered me to convert my levelData into XML. I did an XML version of the levelData's data (question, answers, correct answer...). I used the old class and converted it so that it fetches the XML.
All seems well, I did traces of my answers array and it printed nicely...
But the headache started when I tried this.

// currentLvl:LevelData initialized in the constructor.

ActionScript 3.0 :: Error - Null Object Reference When Creating A Static Variable
Feb 5, 2010Basically 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?

View 4 RepliesActionscript 3 :: Why Is Casting Object (null) Not Null
Mar 6, 2012When you cast null to an object using Object(null), the result is an object.When you cast undefined to an object using Object(undefined), the result is an object.But saying null as Object or undefined as Object remains null.Why is this? I can't find anything in the documentation about this.
The objects that result from these casts can have properties set on and read from them. It's as if the cast created information, or removed whatever special information the null and undefined values have. But there's no indication in the AS3 documentation that the null and undefined special types are actually objects.

ActionScript 3.0 :: Null Object Not Null
Sep 5, 2009I am trying to add an EventListener to a MC, but I am getting the 1009 error. My script is referencing a MC that does exist. I have verified that my code is typed correctly, and that my instance names are correct.I am creating a portfolio site. On the first frame I have my main navigation (well, it's actually not the first frame. I alpha-fade everything in so it's really the 6th or 7th, but I'm not sure how pertinent that is). The main navigation works fine (5 movie clips, fyi). Clicking them will move to a different frame, and the information and sub navigation for the frame will fade up. It is the sub navigation that I am having trouble with.[code]
As you can see, it doesn't even get to the function before it gets thrown off. I have verified that the instance names are correct. The script and the MC I am trying to add it too [I/]are[I/] in the same frame, which is what's stumping me. Normally you get 1009 when the object you're trying to reference is not there, but mine is!!Obviously there is something wrong with my EventListener. I am not sure what else do; there is a gap in my understanding of AS.
