I'm pretty new to working wth custom classes, but so far everything has been working great - up to the point where I create more than one instance of the same kind of class. For example:
[CODE]...
Do I simply have to call the arrays different names??? I really don't want to, shouldn't by creating two different instances you subsequently create two different arrays in turn?
I'm building a simple Pong-esque game and I've 'hit' a problem. I'm having an issue with referencing one variable from one class into another. Sounds confusing to me, even harder to understand.
Basically I've got this in my "game.as" class:
ActionScript Code:
public var pongBall:ball;
and in my "player1.as" class I am trying to get said ball to bounce off the player's bat on contact. I think I have the coding right for it apart from trying to link it to the ball from game.as! So far I have this:
ActionScript Code:
public function bounceTest (event:Event) {
if (this.hitTestObject("game.as".startGame.pongBall)) {
[Code]....
I've created a class that utilizes setInterval...I call it in a different class...and I can't get it to make the setInterval call. I'm thinking there's a scope problem but I don't see it.
Class w/ setInterval:
Code:
class Foo {
private var id:Number;
public function Foo() {[code]....
The function will get called but I need access to the class's instance variables inside display().
Long time ago I've been creating some as 2.0 projects, all of them based on the code within the timeline. I wanted to start learning as 3.0 based on classes rather on timeline but I find it confusing and difficult to understand introduction into the classes. I can't get to understand why the following example is not working :
I've got 3 files:
main.fla with main class "Main"
Code:
no code
Main.as
Code:
package {
import flash.display.MovieClip;
import projectconfig.Configurator;
public class Main extends MovieClip {
var projectConfigurator:Configurator;
[Code] .....
i am creating my own component. the problem is how can i access the variables inside the Class without using _root.myComponentName.variableName.
[Code]....
I have a files that has movie clips and nested movie clips on the stage. I am now writing a class and want to give the MCs event handlers and other properties.
When I do something like the following: myMC_mc.MyOtherMC_mc.mouseEnabled = false;
I get the error: 1120: Access of undefined property myMC_mc.
I added this to the top of my class and it seems to take away the error, but I thought this was not needed in AS3 anymore.
private var myMC_mc:MovieClip;
private var myMC_mc.MyOtherMC_mc:MovieClip;
What do I have to do to not get the error? How is this done right?
I have some classes that I want to be able to target them in xml.[code]...
the two ways I know of to embed the class is to associate it with an exported symbol or just reference the class name somewhere in the code (like just sticking the reference in the document class constructor)[code]...
i retrieve a list of instances located in a array to manipulate them in a variable holder. Normally, the operations can be made between two instances stored in a simple variable to variable fashion and it works realy fast.I analysed two main operations: retrieving references in a array to a variable and get or set a value from the variable reference.Here are the objects used to perform the test operation:
var v4:Vector.<Person>= new Vector.<Person>();//List of Persons instance
var refHolder:Person; //Typed referencevar refHolder2:*; //Not typed reference
Test #1: looping 200 000 times and only retrieving references from the array v4.[code]........
So my conclusion with that test is that with a typed reference you spend more time assigning a reference than manipulating a value from the reference With a not typed reference, the time spent is in manipulating the reference in the variable.Which one should i use or what should i do to have better performance with manipulating references from arrays?
Here are the files i used to test this:
reference.swf //Online example
reference.zip //Source file
I have a very simple class[code]...
when I click I get "undefined"
How do I get at references that are defined within a class when I am on the timeline
loading external SWF's and its class files hanging around after the movie is unloaded....Its kind of tricky to explain, but you can see it very clearly in this file... http:[url]...Just run the main_stage.fla within flash [mx 04] and you'll see that if you click "Tester A" it will trace out "My Name is Tester A", then if you click on "Tester B" it will load a different swf, with a different class, but still trace out "My Name is Tester A" when it should be "My Name is Tester B"....
I have tried, unloading the swf's, removing the mc_Dropper and re-attaching it, re-declaring the variable testObj as null before declaring the class,
I have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information.
Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown:
"Access of undefined property currentState."
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?
I've broken my Weapon class for simplicity:
ActionScript Code:
package
{
import flash.display.MovieClip;
[Code]....
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?
package{
public class Character{
protected var _hp:uint = 50; //Character Health Points
protected var _power:uint = 5; //Damage dealt
[Code].....
I`m instancing a Character and a Player in the Main Timeline, all in frame 1.
When I use: ""player.attack(character)"" it works fine by itself.
So I added the if (defender._hp <= 0) this.win() which gives me the following error:
1061: Call to a possibly undefined method win through a reference with static type Character.
"defender" is a Character instance, "this" is a Player instance and "win()" is a Player method. I try to call the Player method inside a Character method using the Player instance adding the "." and his method name
Do I really need to define the win() function in the Character class? Is there a bypass to use a subclass method in a parent class method if it`s called from an instance of the subclass?
Ok, this is one of those walls that I know once I can jump over it, I will be a much happier developer again.
I've done tons of reading, and think I have a firm understanding that the general consensus is that if you want to reference something, it needs to be added to the display list, using addChild().
I hate to be defiant, but what if I don't want to?
Or at the very least, what if I want to add a movieclip class to the stage using addChild, and then reference objects inside it?
It is much easier this way than what most people recommend - adding 15 objects via addChild, then setting the x and y for the, etc.
That said, I'm all about using classes and using as3 the way it was meant to be used. So what this is, is a best practices question I guess.
HERE ARE THE STEPS I'M TRYING:
- Create new flash document
- Draw graphic symbol bg, with text field over it, select them, convert to movieclip symbol, and export class name "box", then delete it from stage
- Add document class .as file, which simply adds that class "box" from the library, to the display list using a simple addChild()
- Set a name for that box using box.name = "test" let's say
- Do a simple trace like the following - "getChildByName('test').textFieldName" - it shows up great
- So then, I'll now try to set the text by doing this - getChildByName('test').textFieldName.text = "yo";
That last line above, is what doesn't work. I know I'm referencing wrong, but how would a pro as3 developer, reference something on the stage within a movieclip class, from the document class?
i have a BasicMap.as that takes an Array and populates itself with the MC objects passed to it by a String reference.it inherits from Sprite, and so it just places the objects on its self.then i have a class that inherits from that class, and gives a little more functionality to it, but in order for it to do that, it needs to place the objects not on itself, but instead inside a holder Sprite, so here is my problem:
code:
package Mushroom{
import flash.display.Sprite;
[code]......
I was wondering why my current code for calling a setInterval on a function doesn't work inside my class.I have this code inside one function, calling a second function.
intID = setInterval(selfReferential, dupe, 30, 0x000000);
The selfReferential keyword refers to the current class,but was defined previously (selfReferential = this; ).I get no errors, but the dupe() function is never called.and I had the selfReferential variable replaced with the this keyword at one point as well.
I want to know how to make class instances into listeners and broadcasters, from inside each class. Here is what I am trying specifically... part of the Proj class... (projectiles, as a matter of fact)
Code:
private function listen():Void {
u.register(this);
onUpdate = function(){
step(); // a function I have which makes the projectile move (not shown)
}
}
where "u" is another class, the Updater class with this code...
Code:
class Updater {
// const. --- make this a broadcaster
public function Updater(){

PS: What is the syntax for using AS2 code tags instead of just "[CODE|"?
I am having a problem instantiating a Character class inside of a game class.I am working on converting URL...l these tutorials to A.S. 2.0.[code]
View 2 RepliesNow I would like to use the variable out of class1 in class2 and change the value there.Afterwords use class2 in the main, but I get an error message. Why?
ActionScript Code:

What is the correct syntax to initiate a function in a class similar to constructing an associative array? I have a function that's custom variables is ballooning out and I'd like to label them in the call for sanity sake.
currently:
myClass.myClassFunction("hello world",999,0xff0000);
desired:
myClass.myClassFunction(myText:"hello world",myNumber:999,myColor:0xff0000);
and the class itself for reference:
class com.myClass {
public var myText:String;
public var myNumber:Number;
[code]....
This is what i'm trying to do :
I have 1 class that extends movieclip, let's call it Class0. I have 1 class that extends movieclip, let's call it Class1.
I create an instance of Class0 on stage like : var myClip0:Class0 = new Class0(this, "Class1");
The class Class0 when initializing, will create a new movieclip (myClip1) and add it as child, as an instance of Class1, like myClip0.myClip1. But it's when i create that clip, i want to tell it, it's an instance of Class1, like :
private var myClip1:Class1 = new Class1(this);
Where Class1 could be any class.
How do i pass Class1 to Class0 so it can create it dynamically?? Do i have to use the apply function??
inside Class0, i have a function that does :
Code:
if(subClass){
initSubclass(subClass);
}
[Code].....
Is it "better" to initialize AS3 class variables in the class constructor? Or can I just initialize them to their default value when I declare them at the top of my class? I ask because when there's a lot of class variables, it appears inefficient to declare them in one place and then initialize them in another when I could easily do both in the same place. It one option is better than the other,
[Code]...
Performance wise, is it better to instantiate inside or outside the constructor?
Code:
public class example {
private var _mc:MovieClip = new Movieclip();
[code]......
I have this variables in my movieClip
Code:
onClipEvent (load) {
myVar1 = 200;
myVar2 = 100;
[code]....
Even i click the button it doesn't add variables inside the Movieclip I tried it outside the movie clip and it works.
On my main root frame i have this [code]...
i have a symbol called character and inside that symbol i have a symbol called head and inside that symbol i have a variable called headtype... i want it to set to 5 from the main frame.
If I have a MovieClip called parent_mc and inside it I have another called child1_mc, I can use a variable for the "1" part of child1_mc and change the alpha for example like this:
ActionScript Code:
var myVar:Number = 1;
parent_mc['child'+myVar+'_mc'].alpha = 0.5;
What is the right syntax to use if child1_mc is not actually a child of anything and just sits on the stage? I have tried the following and it didn't work:
ActionScript Code:
['child'+myVar+'_mc'].alpha = 0.5;
and I tried:
ActionScript Code:
stage['child'+myVar+'_mc'].alpha = 0.5;
That didn't work either.
I am doing my first simple game using Flash CS5 and Actionscript 3.0. In this game the player would be able to create a new quiz where it would create an array and add sets of questions and answers to that array. I have been looking on how to do this or anything like it and it doesn't seem to be possible (at least in this way).
View 9 RepliesI'm pretty new to AS, I understand that whatever variables you have inside a function will be discarded once the function finishes? I need the value of a variable that's inside a function, I've tried declaring it outside the function, and also give it an initial value, but it seems that when the function finishes the variable goes back to it's original value.

I know that as long as a I declare variables inside a function I can only call them as long as the scope of the function is active. Outside of that function the variables don't exist. Is there any way I can create those variables inside a function and use them outside of it?
