View 0 RepliesI am wanted to know how can i pass a parameter to the function which I'm calling using Delegate class. I know to pass params having static values such as true / false or a static string "hello".
Code:
var myFunc:Function = btn.onRelease = Delegate.create(tihs, releaseHandler);
myFunc.str = "hello";
function releaseHandler()

Here str can be retrieved as 'arguments.caller.str' inside the function.But in case i want to pass the reference of the 'btn' button. Then how can i do this ?

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.
What is the advantage of using a Delegate class in as2? I realize that it's old news for as3 guys. But Ive got a medium sized as2 project and Im going through my code and wondering why Im using Delegate.create sometimes. What's wrong with "apply"?I admit that I must have jumped on the Delegate bandwagon without thinking anything more than "dhuu...thats what the pros must be using".Am I right in saying that there is nothing at all wrong with simply saying "function_name.apply( this, args )"? Or am I missing something? Is it a matter of memory management? I've done a lot of research on delegation and read all kinds of blogs and scripts from little tweeks to the official.. to >200 lines. Yikes! At the end of the day I wrote my own little delegate class that worked for me (just a rewrite of Proxy without loops). But now that I go though my code I see that I might as well have just used apply because that's all Im doing with it!
Id like to be a better programmer. What am I missing and why shouldn't I do a find and replace here. Why is it better to wrap up "apply"? Will I be better readied to learn other languages?I just don't understand why I was so convinced that I needed the delegate class when I had "apply" out of the box.
I have a ColorPicker Component and I want to (on its CHANGE EVENT) have the LISTENER OBJECT ( known as A) change ANOTHER OBJECT's (known as B) color, based on the ColorPicker's.selectedColor. I do this because i need OBJECT A to keep track of the colors used. Also OBJECT B is dynamic and its instance is based on USER INTERACTION thus B can equal B1 or B2 or C based on mouse click at any given time but must only be 1 at any given time. SO I'm trying to "chain" the events together using listeners/ or delegation but I'm not sure at the logic.how do i reference the objects in the event? should I just try to chain B to listen directly to the event? How can I do this without having to attach listers to the colorpicker every time?
View 8 RepliesI'm having a hard time understanding to use the Delegate class. I don't seem to understand what it does from what I read online.
Will it work for this situation? I want to rollover a menu that expands onRollover. You can then click on buttons within the rolled over portion. Is delegate for me?
I've got records being populated into our database from paypal's Instant payment notification methods...great. now i turn to our flash cs3 app to populate a component datagrid with the stored database data and to my surprise I'm unable to identify any examples on how this might even be done.
How do you connect to an mssql database from within flash cs3 to retrieve data for displaying within a flash datagrid?
I can write a cfc from coldfusion to return a dataset, but overall i'm not sure if i 'have' to learn Flex, or AIR or what to get the records 'read'.
My ActionScript 3.0 bible is vague at best and resorts to php. (which i dont know)
when i'm coding directly on the timeline, i usually create a var like this:
Code:
var home:MovieClip = this;
so i always have something to reference the main timeline's scope. how could i do this in a class? delegate.create gets a little confusing.
i tried a few things like the following:
Code:
class com.myClass
{
public var className:String = "myClass";
public static var version:String = "0.0.1";
[code]...
of course this is redundant because it'll scope just fine as parseNews();, but i'm just wondering why it's letting me scope it like this here and not in the onLoad declaration?
I am using a delegate sub-class to perform helper functions for the main app.I have passed all references to it that it needs and it works well apart from the following problem:I also want it to remove an event listener from the main pp.eg:thisStage.removeEventListener(MouseEvent.MOUSE_UP,preOutsideBoundsDragRelease);The compiler tells me I need a reference to "preOutsideBoundsDragRelease" within the removeEventListener statement.eg: "access of undefined property preOutsideBoundsDragRelease
View 1 Repliesi instantiate a sprite-class "panel" from my main class. then i call a function "show chooser" inside "panel" which instatiates a sprite class "chooser" with some buttons. now when one of the buttons is pressed i need to call a function inside "panel" which removes the "chooser" sprite/class and which calls a function "onChosen" in the main class.
what is the correct/best way to reference these functions so that they can be called from within the panel and/or chooser classes. i am still too much in the old thinking that a function belongs to a movieclip and can functions with _parent. i need to learn the proper way now.
How can I get around using an instance variable in a static function that must be called by the Delegate method?
View 6 RepliesI need to separate the visual part of a component from the functional part of a component, so that I'm able to replace the visual one with a new one for another platform.
Declaring an instance variable _delegate with the delegate's interface isn't a problem. But how Do I forward non-implemented method calls of the visual part to those of the delegate.
What's the equivalent of PHP's _call()?
I'm using Delegates in a new project I'm working on to call an event handler in my class with the scope of the class.
I'm having an issue referencing which button is calling this handler. Since all of my buttons are created dynamicly, this is a big problem.
I'm used to using forms and components where I had no problem with this and could reference who was calling the event handler by using - event.target
This doesn't seem to be the case with movieclips though, is there another way to do this?
Is it possible to delegate heavy computations to be handled asynchronously (on the user's machine)? When it's done, I could just fire an event, catch the new data, and update. I have played with this for lesser operations, by just setting up a que and only handle a few operations per frame; but is there another method? That feels like a heavy handed workaround, and it won't scale with faster/slower machines. IE: 12 operations per frame works fine on the test machine, but my machine can handle more, but won't do it because it's hard coded.
View 2 RepliesI am encountering a problem in my app only when it is run in flash player 10.1.85.3. Some earlier player versions I have tried are working fine.From what I can tell it seems related to the following:

When searching for objects (not strings) in Dictionary objects using the 'in' operator, if the object is not found in the Dictionary object, it will be searched for in the delegate objects. With 10.1, the toString operator will be called on the Object if not found in the Dictionary. This can cause problems with Proxy objects who need to define the callProperty function or it will generate a RTE. ...what it means "it will be searched for in the delegate objects"?

I have two classes. The Main class calls a function, which is defined in a Second class.I'm getting the following error:Error 1120: Access of undefined property myFunctionBasically, I am creating buttons in the Main class that will add a corresponding Child to an Object in the Second class (if you click one button, child x1 will be added, if you click another button, child x2 will be added, and so forth).Here's the relevant code for the Main.as file:
package
{
import flash.display.MovieClip;
[code].....
If I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()

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 have question regarding removing instantiated objects. Let's say i have a main class in which i instantiate a custom video player (or whatever) class:
Code:

var videoPlayer = new VideoPlayer(...);
addChild(videoPlayer);

And inside VideoPlayer class i have of course dozens of objects (movie clips, sprites representing different parts of VideoPlayer) and dozens of event listeners attached to them. My question is, if i want to remove this VideoPlayer class from my main class is it enough to just do:

i) Create a symbol called SimpleSquare. This should consist of a simple red square graphic
ii) Create a class file to define a class called SimpleSquare. This should be linked to the SimpleSquare symbol. SimpleSquare ashould have the following functionality: When the instance is placed on the Stage, it should start to disappear by decreasing its alpha at 0.01 in every frame (hint: alpha)
Assume I know practically nothing about AS3! I'm using Flash Pro CS5. I'm trying to reassociate a flash file I've been given with its external assets and classes. In the library I have a movieclip with linkage to a class called 'StaticMap' using the base class 'flash.display.MovieClip'. am I missing a custom class file called 'StaticMap.as' that was originally located in the same folder as the fla, or is this a generic class accessible to all movieClips from within Flash?
