ActionScript 3.0 :: Class Constructor - Update An Xml File Listing The Characters?
Nov 25, 2006
i'm trying to create some code which would create instances of arbitrary classes.for example... i'm making a game which will be hosted on a site, and characters i create over time will eventually be selectable for use in game. but instead of uploading an entirely new game whenever i decide to add a new character, i'd prefer to just update an xml file listing the characters, as well as an swf file for each character class.so during actual runtime, i'd have to create instances of these characters.... but i wouldn't necesarily know which character class constructor i'd be creating.... it would depend on who the user selects.if it were up to me, i'd be able to decide what class instance i'd like to make from a string variable (taken from xml).like this maybe...
var classname:String = "CharacterOne()";
var character:Object = new classname;
....instead of having to write: var character:CharacterOne = new CharacterOne();
constructor function in a Class file. I've built several over my day and never heard a 'proper' answer about them. If your constructor function does nothing, not even set vars or listeners
ActionScript Code: public function MyClass():void{ }
is it proper to keep it in the Class file or is it ok to leave it out completely?Or is this just something of preference? What do you guys think/do?
I have extended an mxml component with an actionscript class. I'm trying to access a component in the mxml file using the id (in order to add an event listener) but I cant seem to do it.
I get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
i had a flash class file for my movie clip in the stage .i had written all necessary codes in the class file. when i test the movie the class file works fine. But when i updated the class file with new code it doesn't seems to be updated in fact the movie clip runs with the last saved class file.But when i change the class name and file name(to a new name) of the class file the movie clip is updating. So what goes wrong here?? Do i need to change the class name and the file name for each update????
I have lost the AS 2.0 Class file for this script, can someone look at my flash file and see if you can get it to work? this program list stores for a company, the drop down menu serves as a selector for the states and the scroll box list the stores.ive been trying for 3 weeks now. the script reads external text files to show the information.
I am creating a Weapon class for a game and the weapons itself will be the sub classes. The sub classes will hard code some values (such as max ammo and the weapon name).
I trying to access this declared data in the base class constructor, at the moment it's not outputting the values. Is this possible?
My current workaround is creating a protected method in the base class to trace the information and calling that method in the sub class's constructor, this works fine but this doesn't seem like the most efficient technique?
I am trying to things efficiently and put as little code as possible on the timeline.
I have a document class loading and working at runtime.
It creates a button that takes me to a different frame on the timeline.
I have a movie clip there. I put a trace in the constructor of the class of that movie clip but it will not show the trace comment in the output window-its not working. There are no errors.
I also tried instantiating the same movie clip from the document class-which worked-but the trace in it's class's constructor still does not output.
I'm making a class called 'player', and really, I don't need a constructor function for it. Do you just outline the function, but don't put anything between the curly braces? Also, I'm a bit new with access levels. If I wanted my functions from my player class to be accessible from the main class, do I make them public?
For Example: package{ public class A { var test:String; public function A() }} class B{ } The code is in the same file, we call B is inner class, then how to call the constructor of class B
I'm doing something - probably very stupid - with an external library swf. That swf so far contains two buttons each with their own classes 'Simple_Button' and 'Simple_Pop_Button'. In the library swf document class I set up an object that lists the available classes:
i have some pretty simple code, i have my document class trying to add a santa class to the stage (simple game ) - but it will not add and i get not errors at all,Santa class:
I have a custom class, MyMC. The only argument the constructor takes is a string, which sets the text of a label inside MyMC.
In the Flash IDE I've placed an instance of MyMC, which is called mcOnStage, on the stage. Through the document's class Main I'd want to perform the constructor function of mcOnStage.
In the AS3 there is a remark, that a Class Constructor is just a method of the class, that is executed when an object of that class is created. So, since the constructor is just a method of a class, how can I call it directly from the other class methods?
I fell on an unexpected comportment with AS3 class definitions this morning. To tell it quickly, I cannot create an instance of a class inside the same class methods.
Here is an exemple :
package { import flash.display.MovieClip; import flash.events.Event; public class Test extends MovieClip {
[code]....
I would like to understand the sub-process that prevents to do that.
I have a document class name elevator and my constructor is also elevator as usualHow to call this constructor function within elevator class? Is is possible or not?
i have been working on this project. I made a class with a empty blank symbol.
package { public class imgHold extends MovieClip { public function imgHold (imgSrc:String)[code]....
I want to be able to add this class on my stage and put in a string in the contructor parameter and the class will display w/e symbol accordingly. How would i make this class link to different symbols depending on the parameter in the contructor?
This is my first post. I'm new to actionscript, but not to programming. I hope to learn a lot from these forums. To the point: I decided a few days ago that I wanted to create a flash game. I'm taking an object-oriented approach to the game design since that is what I know. The issue I am having is that I have a class called Hero that inherits from a class called Entity. Now my issue is that I don't want Hero to call the Entities class constructor when I initialize a new Entity.
I'm currently writing a class where I'd like to call the class constructor without having to instantiate the class itself. Something like this : Class:
[Code]...
trace(testString); //wil trace the text "test test123" Is it possible to somehow achieve this? When I write the costructor method like "public static function ClassName" it fails. Is there any other way?
I have flash application with main document class, components which are on the scene are instancied at runtime, contrustor of these components are call before main class, but i'd like to execute code before main class and components instanciation, how can i do this ? i tried to create an actionscript layer at frame 1 but still not work.
