Flash :: Referencing Static Variables From Frame Scripts?
Oct 27, 2009
Got some external classes, say MyClass.as MyClass.as has a static variable called foo
So, ordinarily in other AS files I can call this with MyClass.foo = bar;
However, this seems to be different in timeline scripts. Every time I try this I get the reference with a static type error 1119: Access of possibly undefined property foo through a reference with static type flash.display:DisplayObjectContainer.
I've tried doing an import MyClass, etc... nothing seems to be firing.
The behaviour looks little weird for me and dont know how to get valus through static property from an array:
[Code]....
but if I initialize missions with values not in the construtor but through variable initialization I gets output = 4; why is that? Doesnt static class initialize its variables in the constructor statement??
When I set a breakpoint and debug my application, Flash Builder 4 is not displaying static variables within the variables window. I'm using flash builder 4 to execute flex unit tests on one of my AS3 classes. I set a static variable within the [Before] function, which is accessed in each of the tests. I've set a breakpoint within one of the tests to see why it is failing, but I notice that static variables don't appear when I expand the 'this' object within the variables window. (In this case my static variable is the only variable associated with the class, so the only object in the variables window is the "this" object). How to make static variables appear in the variables window?
I have a character, And in its movieclip I`ve got 3 frames (first has an idle pose, second a walking pose and third a running pose), each with a movieclip with an action in it.Well, what I wanted is that when I am walking with this character, and press the SHIFT key he runs.And I`ve got the following code
if (Key.isDown(Key.LEFT))[code]....
But when I click the shift button, he shows the first frame static of the movie clip in frame 3 (running frame).
I have a bunch of variables in a class. There are situations when I want to set then to null/ "temp" etc as per a well defined logic. The challenge is to list out the variables at multiple places- tedious and error-prone.
would prefer a way to refer to these variables programatically and set something like "for all class variables- if variable ends in type, set as "not_set"; for other variables set as NaN How can I achieve this?
I am having trouble referencing a MovieClip based on certain variables in my code. I am using Flash Player 9 as the player setting and ActionScript 3.
I have a symbol with a name "Check1" set as a MovieClip, exported for ActionScript, I have ten of these on the stage with an Instance Name of ch0, ch1, ch2...ch9.
Each ch? has 21 frames on the timeline, each with a label name (named with a Number reference "00", "32", etc...) and a different image in each keyframe.
What I would like to do based on these variables:
Code: iTurn = 1; iLeft = 3; iRight = 2;
This is how I would like to use it:
Code: Check1.ch[iTurn].gotoAndStop(iLeft+iRight);
//iLeft & iRight as a frame label and not a frame number, so in the case I would like to access framelabel "32" which is frame 10 on the timeline.
I have tried many way to try and make this work with no luck, the only way I have been able to make it work is by using:
Code: ch1.gotoAndStop("32");
Doing this, I would have 10 clips, each with 21 possibilities. I can do this with many lines of code but I have been unable to tighten it into smaller code.
I have a number of 'TweenField' instances created in a for loop. The problem is that each time the loop increments, the 'myTweenField' variable has the same name, so I don't know how they can be referenced individually from elsewhere in the script. How can I rewrite it so that each instance has a unique name, and how would I then reference it from outside the loop?
I'm having trouble referencing variables in a loaded movie. I read in other posts that you simply refer to the variable as if it belongs to the clip you load it into, however this doesn't seem to be working for me
Hey guys. It's been a while since I've used Flash and I am still trying to wrap my head around Actionscript 3.0 and the way it works; I am so used to the way AS2 works.I have provided the code below, it's very simple, so you might be able to skip this explanation and just take a look at the error and the code:
- I have made a movieclip called HeroMC in my FLA.
- The HeroMC movieclip has the AS Class linkage of exactly the same name, "HeroMC".
- I have made an actionscript class file, HeroMC.as, to house specific variables for my hero; such as Name, Age, xPos and yPos.
- I have also made an actionscript class file, Main.as, the document class for this FLA.
- In Main.as I instantiate HeroMC using the variable hero, and then run the function addHero() from my constructor.
- addHero() is a simple stage.addChild(hero);
This all works perfectly fine and it adds my hero to the stage. However, the problem arises whenever I try to reference one of the variables from HeroMC.as. I am met with this error - I will use the variable xPos as an example.
Here is the error:
1119: Access of possibly undefined property xPos through a reference with static type HeroMC.
It is obvious this is a very simple problem, but I have searched Google, Kirupa and Flashkit for an answer, but none of the threads I find discuss my specific circumstances and I am unable to find the specific information I need to.
I am getting an error that says that 'text_so' is an undefined property and that I can't access it. Yes, I have not declared 'text_so' in 'Reciever.as'. However it is the shared object instance from the 'Text_SO.as' file. How do I reference it from the 'Reciever.as' so that I won't get this error anymore?
I am trying to display in 'Reciever.swf' the value a shared object updated in 'TextSO.swf' . The following is my code for the Reciever[code].,...

A reference to the prototype object of a class or function object. The prototype property is automatically created and attached to any class or function object that you create.This property is static in that it is specific to the class or function that you create. For example, if you create a class, the value of the prototype property is shared by all instances of the class and is accessible only as a class property.Instances of your class cannot directly access the prototype property. A class's prototype object is a special instance of that class that provides a mechanism for sharing state across all instances of a class. At run time, when a property is not found on a class instance, the delegate, which is the class prototype object, is checked for that property. If the prototype object does not contain the property, the process continues with the prototype object's delegate checking in consecutively higher levels in the hierarchy until Flash Player or the Adobe Integrated Runtime finds the property.
Note: In ActionScript 3.0, prototype inheritance is not the primary mechanism for inheritance. Class inheritance, which drives the inheritance of fixed properties in class definitions, is the primary inheritance mechanism in ActionScript 3.0.
from this I get the impression that prototypes are just static variables.. am I right?
I have created a class to define my main navigation buttons. I would like to handle which button is clicked/pressed as simply and elegantly as possible, and I figured the best way would be to add a static variable to the class that keeps track of the current button pressed. Here's some quick pseudo-code. Code: class MainButton ext MC static var currentButton:MainButton public var sectionToLoad:String public static function getCurrentButton() public function getSection() button.onPress = currentButton = this // other button actions. // then i can check for what the currently clicked button // is and now access its variables. MainButton.getCurrentButton().getSection() etc. etc. etc. I am curious if this is a "proper" way to go about tracking the buttons. I find it is pretty elegant, but i'd rather make sure that this is a good practice of using static class variables. Also, it looks to me that all custom class definitions become a _global object?
I have an object present in frame 3 of the main timeline. When the object was present in frame 1 i could access it from an as3 code file. But when I am keeping the object in frame 3 of the timeline (Please note that the previous frames for that layer is blank). I am getting a null value for the object. if I try to use trace the object.Logically if I am in frame 3 i should be able to access it.
I'm a .net developer making a small website on Flash. I noticed that when I initialize a static variable during runtime in one place I cannot get its new value at another place, why?
Say I have a class called Ball (movieclip) and I create a number of instances of it. There is a static variable, say, ballArray and need to access that from a different class, say, Bat. How do I go through with it? Can I access that using the class name itself (Ball.ballArray like in Java)?
I've always used this way to refer to variables on my document class Code: MovieClip(root).variablename But that complicates things because I would need to extend my class as a displayObject and then add it to the displaylist to be able to use "MovieClip(root)" to access the variables in my document class.. as long as variables in my document class are set out as public variables..
I didn't realise you could refer to variables on the document class by just using something like: Code: documentclassname.variablename With the the variable on the document class as "public static var". This solves a lot of problems.. as now I do not need to keep adding objects to the displaylist to get access to the document class variables..
Now.. My question is..Since I want to access most of my variables on my document class.. I would need to set them all to "public static var".. Would setting 100 or so variables to "public static var".. have any disadvantages? Like performance issues... Or anything else which may make it not be as efficent if I were to keep them simply as "public var" and use "MovieClip(root).variable" to access them?
I have a frame that I want to display but the function that calls it exists on the parentHow do I call a frame that exists within a child movieclip from its parent?Here is my code. It is basically for a restart button.Here is the parent function.
I have this issue with action script I've written (AS2), it is simple movement code for an on-screen character.
I have a character set up with a hierarchy of nested movie clips and frame labels.
Main character MC (1 frame, no label) | Front/Side/Back pose MCs (several separate frames, with labels, no animations) | Animation MCs for single pose (e.g. idle, walk, crouch, etc) (several separate frames, with labels)
I want to reference the child frame labels with gotoAndStop ('Front.walk'), or similar...
Here is the code I have now:
keyListener = new Object();
keyListener.onKeyDown = function () {
[Code]....
The problem is, as soon as the character moves one direction and changes to the desired pose, when I try to go the opposite direction... the pose doesn't change to the opposite direction frame label. So it only works once, and stays on that child frame label.
Is there a problem with the way I'm referencing the child frame labels?
I'm trying to make methods available like so: ActionScript Code: MyClass.myFunc(); Instead of ActionScript Code: var myVar:MyClass = new MyClass(); myVar.myFunc();
I know that to do so I need to declare the functions/variables/constants as static: ActionScript Code: package MyPackage { public class MyClass extends Object { public static function myFunc():void { } public function MyClass() { [Code] .....
When I try to access the static function through the full reference (i.e trace(MyPackage.MyClass.myFunc);), it works, while trace(MyClass.myFunc); returns undefined. This contradicts what I've read in tutorials and posts on the Internet. They all use the short syntax, not the full path.
I'm literally new in AS3 and slowly trying to migrate in thats why im here seeking for help. Can someone help me how to access/control a certain public variable in a loaded swf from the main swf? this problem has been paralyzing me for days. (sigh...) [code]...
I'm working with a movieclip right now that has two frames in it. I want the user to be able to go back and forth between the pages by clicking on tabs on either page. The button that they click on is only present on the frame that it is applicable (so, the button to switch to frame 2 is only present on frame 1, and vice versa).
I want to control when they are able to click back and forth, and be able to turn the buttons on and off whenever I need to, but since the button to switch back to frame 1 is only on frame 2, when I reference it from the main timeline, the button registers as a null object. How do I refrence an object that is not present on the first frame of a clip?
pros and cons of either using a Singleton that enforces only one instantiation of itself, versus creating one common class with static vars which can be accessed by all other classes that import it?
In my testing, importing but never instantiating works fine. I can even change the value of one of the variables and then have another class see that changed value later on in the program.
If I *know* I will never actually create an instance of my Global class using the New command (but will instead just reference the variables using the class's name), then why should I need to make it a strict Singleton?
I get this error 1120: Access of undefined property OtherClass.
Ths is the code: Code: public class SomeClass extends MovieClip { function SomeClass():void { } public function SomeFunction():void { var i:int = OtherClass.myVar; trace(i); }}
Code: public class OtherClass { public static var myVar:int = 2; public function OtherClass():void { }}
I'm trying access a static variable located of a super class through an instance of one of it's subclasses and I'm receiving an access of undefined property error (example of which below). Creating another static variable in the subclass and assigning the value from the super class will allow me to dot operate to it.
How do I reference the root frame label in a function for event dispatching using a switch statement.
SUMMARY: This is simple, but as I've stepped away from ActionScript for too long, I'm having trouble figuring out the proper test expression to reference the root timeline frame label (e.g., switch(the root frame label)).
Nothing i've tried works: switch(this.label)://obviously this would look at the button timeline switch(event.root.label)://player says there is no "root" property ...
STRUCTURE: I have five MCs, one on each of five frames. I have a forward button and a back button. I created a switch statement to specify different actions, based on the root frame label. Frame labels are f1, f2, f3, f4, fend.
