I have been busy building the UI for a class file I wrote a while ago.
The problem I have is in referencing the symbols on the TimeLine. All the symbols have an instance name, and only exist in the first frame (main timeline has only one frame anyway).
At the moment I am instantiating my AS3 class file from a timeline layer using[code]...
this is one of those upsurdly basic questions for which google does not work. I have usually dispatched events from my classes and dealt with the user interface in the document class. But now i want to separate all the UI in a separate class, accessible by other classes. have added it as a child to the main/document class, but how do i reference the main class without going through parent.parent shananigans?dit. one more thing i remembered. Some of my UI elements are not programatically added.here is the code i have. i get possibly undefined property error.
package rpflash.ui {
import flash.display.Sprite;
import flash.display.MovieClip;

I've often seen on various websites headings that were created from Flash-based text. A good example of what I'm referring to is on vancouver2010.com , most notably on pages other than the homepage. I was wondering if anyone knows if there's a way to do this automatically with a text generator perhaps, or if I need to manually create each SWF file by hand in Flash if I wanted to do this. I've also seen headers created that appear to have come from a generator of sorts that are just images.
View 2 RepliesI'm using Flash CS3 to build a simple drawing application. When the user clicks a button, they select a particular movieclip. After clicking elsewhere on the stage, the clip is instantiated and added to the stage at the position of the cursor. I've also added the option of being able to click on the added clip and drag it around on the screen. And this all works fine.
The problem is that I also want to be able to dynamically draw and add objects to the stage via the Graphics class. Whenever I add objects in this manner, their x and y coordinates are always 0,0 no matter where I place them on the stage. This makes positioning these graphics very very problematic. I created a modified positioning function specifically for these dynamically drawn graphics and while it does "work", it feels less responsive than the positioning for movieclip objects. I'm still trying to optimize this function, but it seems to me that the ideal solution is for the graphics to have non-zero coordinates when placed in the middle of the stage like movieclip objects. Is there some "workaround" to achieve this?
I have created a class, call it Class1, that has various objects drawn on the stage (drawn in the IDE). It also has a function, called setColour, for changing the colour of those objects. The function works fine if I call it from within Class1.
Now I have another class, call it testClass1, that imports Class1 and calls the setColour function. First of all, none of the stage objects from Class1 are visible. Secondly, when setColour tries to modify the colour of an object, I get the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
This is the code for testClass1:
ActionScript Code:
package
{
import flash.display.*;
[Code].....
So, what is the problem? Is it possible to change objects that are drawn on the stage of an imported class?
I have a class file that creates an array of image paths from an xml file. i need to know how to from the main stage refrance to get that array.

Trying to migrate to AS 3.0 here, but are facing a tough time at kick-off: I have a base fla file located in a folder named "game". The "game" folder is in a folder named "northcreek" which again is in a folder named "no". For no other reason than that I read somewhere that this was smart. Anyway, I have in my (document) class under publish settings this: no.northcreek.game.Engine Both my "game.fla" and my "Engine.as" reside in the "game" folder, but I fail to reference my as-class from my fla file. What do I do wrong? It works if I simply remove all namespace names, and only type namespace, but I am trying to do it the right way here...
View 8 RepliesI've been searching around all afternoon, and am pulling my hair out. 1) I have a movieclip instance on stage (simple graphical element that represents platforms for a hero to run and jump along). I have placed it on the stage with an external class engine.as and in this class it is called myPlatform and is an object of Platforms.as. The movieClip is called platforms and from a trace(myPlatform.name) the instance name is instance3.
2) I am attempting to access the properties of myPlatform in an Enterframe event loop in my character control and collision class (called hero.as)
Basically here is the bit of code I am trying implement within Hero.as :
[Code]...
This all worked when I was writing actionscipt within the FLA file, on the timeline frame 1. I simply don't know how to access myPlatform from within the external Hero.as class! Do I need to create a variable? Is there a really easy way to do this with some syntax/command that I have not learned yet?
Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:
stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)

I have a MovieClip in the library with a class associated with it. I can instanciate the MovieClip just fine using code and add it to the stage without any problems. But how can I manually add the MovieClip to the stage and feed it the one parameter when it's instanciated? I've tried all the usual stuff but nothing seems to work:
var testClip:className = new className("helloworld");
testClip is the name of the MovieClip that's been manually placed on the stage.
I'm working through a book called Foundation Game Design with Flash, and I'm finding the Flash IDE confusing. I've been programming for several years, so working with AS3 directly is far easier than trying to understand symbols and nested symbols and the difference between graphics and movie clips and scoping issues and all that -- when tied into the IDE.
How many of you who are making games in AS3 also use the Flash IDE? Can anyone recommend a resource that is AS3 heavy and Flash IDE light? I don't care how much time I may or may not save by using things like the timeline, I just want to understand what I'm using.

I am doing a looping background with 2 identical BG movieClip (B1 and B2). Those 2 are "new" by the same class.
var B1:MovieClip = new BG();
var B2:MovieClip = new BG();
But because this BG class picture is loader from the internet and the picture is rather big. When I addressed its loading by using progressEvent. The picture is really loaded 2 times. Is there anyway I create B2 based on B1 without using new BG() again? Since it definitely makes a new BG with Loader code inside.

Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?

View 1 RepliesI am downloading large files in the browser using a swf coded in as3 that makes byte range http requests (using http:url....).This lets me download the files in chunks.Is it possible to manually cache the file byte ranges to the browser cache so that I can prevent wasting bandwidth if the client has already downloaded a portion of the file on the next visit? This would essentially be a "resume download" feature.
From what I can find on adobe livedocs, flash player will not allow this because of security issues. I just wanted to double check and see if anyone knew a way to do this
I have a list of 700 words that I would like to convert to symbols in Flash for a flash card game. I'm trying to make a game where a random symbol from a slice of the array of symbols will come into game play until the user performs an action.Basically, I'm wondering how I can create an arrayed/indexed library of symbols from a dictionary, for a downloadable Flash game. Does anyone know how I could start to script this? Also, if I want to pair a 'word symbol' with its translation, do I need to use a database? Obviously, because it's a flash-card type game I'm working on, the translated symbol is just as valuable as the original-language symbol.
View 1 RepliesWell I've been searching the web and knocking my head against the wall long enough to justify an inquiry.
Anybody know an elegant way to get a usable reference to a class in a loaded swf?
I find that this approach, from Big Spaceship, produces an error, when compiler is forced to try to convert type "Ball" to type "MovieClip." Sheesh.
Code:
var loader:Loader = new Loader();
var nuSquare:MovieClip;
var nuBall:MovieClip;

Is there a way to search for symbols by the class they are using? I have a large projectand at times (specifically when refactoring)
View 2 RepliesIn my library I have a few symbols (with diffrent graphics) that I want to share the same class (the same methods I written in as3).
First I tried to set the same name on the class line when converting to symbol but Flash then tells me that the name have to be unique. So I tried diffrent ways of inherit the class in each symbols custom class, but I didn't get that to work either..
Is there a way for 1 class to have multiple symbols, (not individual instances but symbols) Or should I just make a major Class with minor classes extending that one class?

I've got a question which is primarily an OOP question, but it is specific to AS3 in it's implementation.
I writing an interface which consists of displaying a (circuit) card rack which holds twenty cards of various types. Some of the properties of the cards are common to all cards such as slot number, card type, id, etc. They also behave similar when clicked on, taking you to another view.
It seems to make sense to create an abstract class (Card) that has all the common properties and behavior of all the cards, and then extend that class to create the specific card types, but the problem is that the display objects representing the cards are movie clip symbols in the library.
It boils down to this question: How do I extend a class that is already extending the movie clip class (a symbol in the library)? I know that AS3 doesn't allow it, but I figured someone has probably run in to something like this before.
I frequently create a lot of Library Symbols, export for Actionscript, letting Flash auto-generate the Class & extending a custom base-class in order to give them all custom functionality w/out having to create a Class for each, and/or without having to create a FactoryClass for instantiating X number of ClassObjects for each Symbol to be added to.It's really fast for prototyping, and with this workflow I've only hit a few obstacles. Those are:
1 - If the Symbol has children you cannot give the children instance-names, else the compiler gives an error related to automatically declaring stage instances. Two workarounds for this are that you can uncheck automatically declare stage instances, and do it manually in your base-class. or you can avoid using instance-names, and use getChildAt().
2 - If the Symbol is a MovieClip, the timeline doesn't inherit the base-classes imports. I don't have a workaround for this.are these limitations that could be addressed by Adobe's Flash team, or are they limitations that are unavoidable without altering the workflow?
I've started a new cs3 flash file. I've created a few symbols, scattered them about the stage, then gone to start writing my class file. I've created the class fine and i have created an external .as with the same name as the fla file (miniGolf.fla and miniGolf.as). The problem is that i can't link the fla to the .as. Every time I click the little pencil icon I get an error saying:
"You must specify a unique class name that is not associated with any library symbols"
Is there anyway that Actionscript allows multiple symbols to be linked to the same class? This is because the symbols' are diff. in appearance but the same in functionality. It seems a bit redundant to create a new class everytime.
View 2 RepliesI'm using Flash Professional cs5/AS3 I'll try and describe this the best I can. I'm new to ActionScript. So, in my timeline I have a var on a frame that represents "lives" and i have some code in the timeline that takes down the number of lives depending on certain events, which all works great.
so, now i wanted to make a constructor class that I could reuse for a bunch of movie clip objects and I only want these objects to be able to move if the lives variable is greater than certain number. So now, building my constructor class for these objects i just wanted put an if statement that is looking to see if the lives are greater than a certain number, which if it is then should make these objects do what i want...But, when i run the project I get "1120: Access of undefined property lives."
lives is the var I made obviously like I said, and it works fine being referenced everyone else except when I make a new .as file for these objects then try and reference it. I get the same error when I try and establish "lives" in the main project class too. I'm not sure where I should put this var or how I can make it so i can reference it from an object class. I'm not really sure how to word or describe my issue which has made it hard to search for a tutorial.
How can I test if a class reference implements an interface? Note that the is and instanceof operators do not work with Class references.
Example:
public function set someClassref(value:Class):void
{
if(value is IMyInterface)[code]........
