I have a rather general question regarding OOP. How do constructor functions execute with multiple class extensions? I'm making an orbital physics simulation, and every spatial body is of the class SpaceObject, which extends Sprite. Then, I have all earth-type planets be of the class Earth, which extends SpaceObject. There are certain parameters that I'd like to set for every single SpaceObject (like position and size) in the constructor function, and certain parameters (like density and mass) that I'd like to set in the constructor of class Earth.But from the main timeline, when I create an instance of class Earth, I can only enter the parameters of the Earth constructor, ie
Code: var planet1:Earth = new Earth(density, mass) Or I can create an instance of SpaceObject:
What is the correct way to import 'sub' classes into a main class?What i have is a class (i call it Console) that gives the user info about the swf for debugging, but also gives the user the ability to give their input to dynamically change the swf. Sorta like what games have when you press the "`" key.But it handles more things then just read user input, it also connects to the Database through PHP and connects through the server using Sockets.And there are more of those things that gets added later, so to prevent it gets to big later i want to split it into multiple .as files
Console Class: renders stuff and allows user input.I want that to include the following classes:
ConnectPHP Class (handles php > mysql) ConnectJava Class (handles sockets)
So that the methods in those 2 classes are accessible in the Console class like:
[code]...
I tried importing them but then i had to access them through the Object initialized:
[code]...
But i want to access them as
[code]...
removing the reference of the ConnectJava Object. Is this possible? If you wonder why, id like to keep it as simple as possible because i share the classes with my friends.
I have created a file called Config.as, in it are getter and setter methods that define variables that I need to reference throughout my system.
I have obviously made a mistake as I tried to access a variable in two files as indicated in a demo below:
Code: package { import Config; public class TestOne {
[Code].....
It seems quite clear to me that I have created two instance of the Config class and that is why in class TestTwo the trace statement doesn't return "hello world". Is there a common coding practice to access the same variable with multiple classes?
package { import flash.display.Sprite; public class MySprite extends Sprite{
[Code]....
and extend that class, if more than one internal classes are defined:
package { public class MainClass extends MySprite { public function MainClass():void{}
[Code]....
ReferenceError: Error #1065: Variable MainClass is not defined.Note that this only happens (as far as I can tell) when the public class of the package extends another class, and multiple internal classes are defined. The internal classes don't even need to be instanced or referenced to generate the error (the bare-bones code above will error out). If only a single internal class is defined, it works fine (no error). Even if the internal class is instanced.
can you declare multiple classes and then register each movieclip from the library to a different class? It isnt working for me.I created two different classes and created two entire different movieClips and registered each movie clips to a different class.However, I can only use on movieClip at a time, when I use the duplicateMovieClip... command to create copies of the movieclip, i find that only those movieclips, whose class i declared first, appear on stage.
Let's I have a class Square that has a several functions. I want to call it from a class Grid, which is a group of Squares.So in the class file for Grid, how would I do this:
Code: public function doSquareFunction(thisFunction:Function):void{ square1.thisFunction();
This is more of a database design issue but almost everybody here uses database integration with their apps so I feel it is important. I am integrating AS3 + mysql + php and need to clear up the database design for multiple students results in various activities. Developing an online e-learning course with a "dashboard" or teacher control panel with all kids results in each activity. I have read the database design rules by Codd etc... understand the need for parent and child tables so information is relational and not duplicated etc... BUT I am not sure how to design the results part. Various students do various lessons with 10 activities which each give a mark out of ten. The table would be updating every few seconds as 10,000 users would be online at the same time
1. Would I create a results table with all the students results going in the same table ie: Tom would be the first row
I'm working with an application which was originally designed to make heavy use of static-variables and functions to impose singleton-style access to objects. I've been utilizing Parsley to break apart some of the coupling in this project, and I'd like to start chiseling away at the use of static functions. I will explain the basic architecture first, and then I'll ask my questions. Within this application exists a static utility which sends/receives HTTP requests. When a component wishes to request data via HTTP, it invokes a static function in this class: Utility.fetchUrl(url, parameters, successHandler, errorHandler); This function calls another static function in a tracking component which monitors how long requests take, how many are sent, etc. The invocation looks very similar in the utility class:
I'm building simple application on as3. Kind of starship game. What I want to do is to create several different star ships. Each one should have different images (different look), different sets of animation (e.g. when it's flying, burning, damaged), different kind of weapon and also different controllers (e.g. one can be managed by user, another one by computer, and I want to be able to reuse same ships for AI controller as well as for users controls). Each ship is created in the following way:
Create entity Add spatial Add renderers Add other components.... ...... n. init the ship
So what I am trying to do:
1) Create StarShip superclass, to store HP (as every ship has it), store spatial (same reason)
2) Create inherited class for any other ship..(It will contain renderer - (responsible for display part), weapon, set of animations), etc
What do you think about such way of composition? Maybe it's better to place everything in super class, and then just create instances using long, long, long constructors like:
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
how to get a Class file up and going in Flash and that works fine but say I want to import other classes. I try "import testCass" above in my import statements section of my as file and that doesn't work. What do I have to do to get that to work?
I have an application that takes the user through a set of steps, configuring a product, say about 10+ screens. With options to go back, skip to a certain point etc. I need to fade between these steps, and also have language switches available at any point.
I was thinking of using an MVC style pattern, having a master view that accepts a 'next view' and fades it in, removing the old.
It feels bloated to have 10+ separate view classes, using similar components for this task, so was wondering what other approaches there are that I should look into? or one that is suited for this kind of application
so I'm having this problem where one of my classes can't locate a function. The function it's trying to use is in another class, so I was wondering if there was something special you had to do. This is what I'm basically doing: One class
Let's I have a class Square that has a several functions. I want to call it from a class Grid, which is a group of Squares.So in the class file for Grid, how would I do this:
Code: public function doSquareFunction(thisFunction:Function):void{ square1.thisFunction();
I have Flash project that is set up something like this:
myProject.fla
- document class = myMenu.as
- the document class imports a menu item from menuItem.as (import menuItem;)
I have a function in myMenu.as that sets the text formatting for all the text fields on the page. I want to be able to use this same function in menuItem.as so that all the formatting is consistent & you only have to change it in one place. How do I access this function from both myMenu.as & menuItem.as?
okay, i'm refactoring a huge ActionScript file, and so trying to move some functions into their own classes. why is this not working? i've got a function in my primary class:
// ... private var testBlock:Sprite; public function testingINT() { testBlock = new Sprite();
I'm coding a small flash game, and wan't to access different functions between classes. In C# I'm used to just making it static, but I'm having some problems with it.Here goes:
This probably has a simple solution, but I'm a complete newb to actionscript and I could really use some guidance.I have a file, called Politismos.fla. The document class of this file is: com.plaidfox.PolitismosClassPolitismosClass.as is as follows:
I've been working my way towards better OOP design lately and I've come across a problem with accessing functions in other classes from my Main class. Here is the code:
They are listening for functions that are within the Player.as class, these functions control the dynamics/movement of the player itelf. But for some reason I'm getting a 1120 error(access of undefined property). Basically how do you listen/access for functions within a different class?
asically I have a Player class with methods (i.e. Moving the player) that I want to listen for and implement in the main class. To put it simply, I'm creating the player methods in the player class and then calling them in the Main class. But for some reason I'm having some trouble, I'm still trying to get used to all this OOP design.Here is the (Main) code, it's not alot:
in my Main class, i try to call a function from another class, but when i compile i get this error:1136: Incorrect number of arguments. Expected 1.i have seen some fixes involving an event in the OtherClass and (null) when i call it, but it dosent seem tohere is a code that describes my problem, what do i have to do to make this kind of code work?m i doing it wrong, or do i have to do something else?OtherClass
There are many times that I've needed to execute some code after a number of events have fired, and I've come up with counters and such but I feel there must be a better way.For example, say five files need to be loaded, after which a UI component will become active.If I set up a counter that increments each time a file is requested, then decrements each time one has loaded, I run the risk that the first two or three files may somehow get completely loaded before my code gets around to requesting the fourth and fifth, which would mean that my counter would be at zero when I still have two files to load, thus allowing the UI component to be prematurely activated.
There are some cases where you could know the number that need to be loaded before the requests go out, but it's possible that the first file contains the paths (and therefore the number of) files.And this file-loading scenario is only an example of the pattern I'm trying to explain.)
I was wondering if ActionScript had some way to call functions and classes from variables, like they do in PHP:
function funcname() { print "Potatoes come from tree"; } $function = "funcname"; print $function; // Prints out "funcname" $$function(); // Prints out "Potatoes come from tree"
In case you don't know the syntax for PHP, you should know that anything perpended with a $-symbol is a variable.
I have a flex application that loads swf files and displays them using the SWFLoader object.is there a way to provide different classes and functions for the swf application to use? [code]...
I have a Flash application that creates a sort of powerpoint presentation. All the 'slides' are stored in an XML files which is read and processed.
I'm trying to build the presentation using this XML file. At the moment, my main class has it's initial function main and a static function processXML main initiates my database class with a function called initDB. One of my issues is that initDB forgoes processing because it's dependant on an event listener. On completion of loading the XML files, the event listener initiates my static function on my main to create objects from this file.
The issue is that because the event listener continues the processing (after an indeterminate amount of time), the functions are no longer controlled by the main class.
