Actionscript 3 :: Flash - Calling A Function From A Class Within A Separate Class?
Feb 4, 2012
I've been searching around trying to work this out for a while now. There's been various ideas popping up, like dispatchEvent etc but nothing that seems to be a clear, simple way of doing this.What I'm trying to do is call a function from a class seperate (but in the same folder as) my document class.Specifically, I want to 'spawn' an object and run a function within that object's class from my Main.as.The snippet I have at the moment is as follows;
In Main.as:
var object:class_Object = new class_Object();
object.spawn();

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?

I'm not sure that I'm on the right track here. I've got what is essentially a 'gateway' movieclip and depending on the CLICK a corresponding movieclip (form) is loaded -- these all being in their own AS file. There are multiple corresponding pages that will all load/close in their own fashion but the 'gateway' will reload in it's own function-- consequently, I have this function on the main_AS. Can I trigger this function from the sub class or do I need to move the 'reload' function to a 'reload' class.

I keep getting an "undefined property" error when I try to call an external function from within the Doc class. I added the error message to the Doc Class below so you can see where it occurs.
If I take the code from the Tooltip.as below and place it on the FLA's main timeline I can get things working fine, but I would like to move all script to classes. The document class structure looks like this:
Drag_and_Drop.as
Code:
package {
import Tooltip;// Import custom class
public class Drag_and_Drop extends MovieClip {
[Code]....
I realize that I could just combine all the code in the Doc class to get it working, but it would be nice to separate out this particular code which has only one use.

I'm trying to have a class reference a variable within the document class and have scoured the web but can't seem to find a solution. It seems relatively simple, but is a major stumbling block for me.
I want the variable in the doc class to increment each time a draggable object is within bounds and snapped to a box in the subclass. By tracking successful snaps, the objects will be placed one under the other each time.

I have a two classes. One is linked to a menu and controls that. The other is linked to a 'viewer' movieclip. At the start (in the contructor function of the classes that relates to that mc) the 'viewer' mc feeds off an XML document, and an image is loaded into itself. When I click on a menu tab I want the image to change.
Both the viewer mc and the menu mc are on stage already. I tried to import the viewer classes into the menu class...

The basic flow is this: On the main timeline I instantiate Ships and vGX.

I've been searching around the forums to find a solution of this problem. I have two classes: Monster and Player. Constructors are defined and the classes by themselves apparently works. My problem is that I want to get player.x inside the Monster class.

I'm trying to call a function to another class after an event.
Here's my code:
From the doucment class:
public static function redrawMap():void {
removeChild(global.world);
var world:WorldHandler = new WorldHandler(40,30);
[Code]....
I can't get it to work correctly, I get weird messages like "Call to undefined method removeChild" and it pointing to the redrawMap function. Which means it found the function, but I can't seem to do anything with it.

Basically I have a function that is needs to tell 2 other classes to do something. It works for one of the classes: BigPlayButton, but not Background for some reason.TabMenu.as Class functionNote: The function below WILL call the hitPlayCircle function in my BigPlayButton class, but I get an undefined property error for the Background switchTitle function.
private function thumbClick(e:MouseEvent = null):void
{
trace("YOU CLICKED THUMBNAIL: " + e.target.id);

I've been hitting dead ends while programming lately all over, and I finally came to the realization all the code I have that is broken is because I don't know how to interact with instances of one class from within another. Here's the gist of what I am trying to do:
if(this.hitTestObject(targetClip)){
trace("hit!");
}
The problem is, if I address a single instance that is on the canvas, I get "access to undefined property targetClip", even though the document class can interact with it fine. If I target the class file of targetClip, I get "Implicit coercion of a value of type Class to an unrelated type flash.display:DisplayObject". It isn't just a problem with hitTest either, I'm having this problem with other actions, so there is some basic syntax I'm failing to comprehend.

I'm new to Flash AS3. I started making a game and I am a bit confused. Let's assume that I want to create a game that has multiple levels/modes, how can I do this in an object orientated way?
When i create games in other languages e.g. XNA C#, i create a separate class then create an object of that class within the main class and run the game based on a simple statement.

I have a rather silly question but as3's document class always gets me confused.I have a public method on my document class. I want to call this method from another class that is instantiated from within an object in the library of the flash file (the same one on whose document class I want to call a method).

I have two classes. One called Sledge and one called Sock, there is also the document class called Main. My issues are as follows: Inside of Sledge, I call a function that is defined inside of the Main document class. How would I go about telling the class to go to the document class and run that function? Would this also be the same for other classes or just for the document class? Inside Sledge, I have the following statement: if(hitTestObject(sock.myHitArea)) { /* somecode*/ }
sock is an instance of another seperate class, and by this point has already been created. However when I try and run this I am told it is not defined. How would i go about solving this?

I have done this type of thing a million times before, but I cannot for the life of me figure out why it isn't working this time. As of now I have three classes: Main, UI, and Bear.
Main creates an instance of UI and puts it on the stage. UI has, among other stuff, 7 instances of the Bear class sitting on the stage. The Bear class has a public function:

I have the following two classes and can't seem to figure to figure out how to call a function in the top one from the bottom one. The top one get instantiated on the root timeline. The bottom one gets instantiated from the top one. How do I call functions between the classes. Also, what if I had another call instantiated in top one and wanted to call a function in the bottom class from the second class?

I have my main stage, and I have two objects (blocks), these two objects both extend from the "Block" class. The "Block" class is NOT extended from the Main Class.I would LIKE to call a function, in either the "Block" class or in it's subclasses, from the Main Stage Class. The functions will do slightly different things depending which object you are calling the function (Added different things, and different number of things to an array). What is the best way to implement this?
