Im looking to have something along these lines, different variables that build the path to the object so that I can have it change dynamically.I'd like to have something like:
function foo(e:MouseEvent):void {
var1.var2.var3+_button.gotoAndPlay(2);
}

I am wrapping my brain around OOP in AS2. I am making two posts on two different subjects. My question here is: when should I use local instance variables, and when should I attach new properties to the instance object? (Feel free to correct my terminology.) Let's say I have a class for a scrolling background, which scrolls when I mouse over its edge. I want to put these values somewhere:
1) How wide is the border in which a mouseOver makes it scroll? This is basically a semi-constant I set it up once and keep it the same, unless the user changes it in an options menu to make the border wider or narrower. Call this scrollBorderWidth.
2) How fast is the background scrolling now? I want to track this so I can smoothly change the scroll speed over several frames. This is often changed. Call this scrollSpeed.
It seems I have two ways I can store and access these values and darned if I know which is better practice. METHOD A: Make them local variables in the class, so the scrolling background instance has them as local vars. I set them up thusly:
[Code]....
Ok, Background. I have two objects both of which im spawining in though code. We will call them bullets and wolves. They have their own .AS files which tells them everything they need to know about themselves. I figured i would do most of the hit testing on the bullet.AS file, hit testing against the wolves as there were going to be a set number of wolves but not a set number of bullets.o, I named them by running a loop and putting the linenewWolf.name = i.toString();Yes, new wolf is a declared variable, and i is the name of the variable that makes the loop run. I also have a test in it, and it works fine.
However, The hit testing is where i come into an issue. Remember, its on a seperate .AS file. The wolf maker and namer is on the main flash page.The hit testing function isif(this.hitTestObject(a)){i changed up my variable name to run a second loop. first variable name is "i" and the second variable name is "a"And for some reason i get a type error 1034, which from what i understand is an error that you get when two instance names are the same. Also, If possible, i would like to add letters to the name of the object, but im not sure if flash will let me as i belive the code would look something like this
I'm using 9 textbox in my stage. Names are similar, only difference is the last character. (s1_0, s1_1, s1_2, ...). I'm trying to use these textbox in a loop. But I couldn't find the right typing... s1_[i], s1_(i) or s1_{i} gives error. s1_0.text=0 s1_1.text=0 s1_2.text=0 s1_3.text=0 s1_4.text=0 s1_5.text=0 s1_6.text=0 s1_7.text=0
View 3 RepliesIt seems that my code is problematic, because I assign one instance of a MovieClip to several variables, type MovieClip. The behaviour of others of my codes makes me think, that ActionScript does not make copies of the instance, but references all variables to this single instance. This behaviour now causes trouble.The solution I consider now, is to create copies of the MovieClip and assign them to my variables. Is there any code to copy a MovieClip?
View 8 RepliesSo in AS2.0 I would use _global.variableName to create and refer to a variable that was maybe created on the stage and then needed to be referenced to inside of an instance. That doesn't seem to work anymore. Are you expected to not want to do that, or is the code just changed now?
View 9 RepliesThere's a way to get the instance name of objects/symbols for variables and use this in actions and/or functions?
View 4 RepliesSo, I have something like..
Code:
select = ("block" + number);
trace(select._currentframe);
number++;
This is because I have 5 movieclips named block1, block2, etc. However, it returns undefined. When I directly state the instance name, like:
Code:
trace(block1._currentframe);
It works. How do I use variables as instance names?
I've read on the net that actionscripting from the action layer will result in a more readable file once published, as apposed to attaching onClipEvent functions which slow down readability.
For this reason I am trying to add variables to a MovieClip I have on the stage with an Instance Name of Player. However I wish to assign the MovieClip variables from the actions layer using the MovieClips Instance Name.
[Code].....
I have created movie clips using loops that names them box1, box2, box3.... via = i + 1;duplicateMovieClip (_root.box, "box" + i, i);but i then want to edit a textbox which is rooted inside each movie but related to the movieclip just produced. so if box1 had just been produced then:box1.textbox.text = " E cell = +j+"V";is done so effectively i am looking to do: box+i.textbox.text = " E cell = "+j+"V";
View 2 RepliesI have defined a variable attached to a move clip via Mc.OnLoad = function *etc so is it possible to access this variable from within the move clip ?
View 2 RepliesI am using the tween class to change the alpha value of a MC upon rollOver and rollOut. To refine the effect, I assigned a variable to the MC's alpha value so if the mouse moves off the MC before it has reached 100% alpha, it wont start immediatly fading from 100%, but from the value it had reached before the user stopped the rollOver action. Unfortunately, when I leave my mouse over the MC until it goes to 100%, and then I wait a second or two, the alpha snaps back to 50% (the starting alpha value).I can't figure out why this keeps happening, but I have run into it with other projects and I surmise it is the way I am using the tween class. Below is the code I used to make this happen.To see the problem, here is a link to the compiled file:
// image 1 Set 2
groupA.group2.image1.onRelease = function() {
loadMovie("main_resized/1.jpg", pictureHolder);

In the following code I would like to be able to change which object the code affects depending on which parameter name is passed to it:
Code:
EventCentral.getInstance().addEventListener(ProjectEvent.SOME_EVENT, handleSomeEvent);
function handleSomeEvent($event:ProjectEvent):void
[Code].....
I could write it all out with ifs and else ifs for each parameter but this code is already part of quite a large structure and it would be more elegant to be able to do it with re-usable code.
I'm trying to do it is particularly idiomatic to actionscript anyway
I have two classes a main and one controlling a cloud graphic going on the stage. In the main class I am creating an instance of the cloud, adding it to the stage with an array and with a for loop I am setting the x speed (vx). I have noticed that if I set the vx in the cloud class and reference it directly then it does not work (clouds are drawn for a millisecond then a blank movie). I have to initialize the cloud.vx value in the main class to get it to work. Why can I not just pull the vx value from the cloud class without setting it to a value in the main class?

picture: [URL].. I am making a boardgame in flash Action Script 3 each position on the board is a buttons like this: button_1_1, button_1_2 etc. Whenever a character is selected you want to move it so the script has to add event listeners for positions around the selected unit
[Code]...
In the rest of the code I have:
function userClickedPosition(position_x:int, position_y:int) it selects or deselect a unit function selectUnit(position_x:int, position_y:int):it uses the listentoButton(1) function to add 8 listeners (the positions around the clicked unit)function deselectUnit(position_x:int, position_y:int): it uses the listentoButton(0) function to delete 8 listeners (the positions around the clicked unit)
My question: adding eventlisteners is no problem but removing them dont seem to work? What did I do wrong?
I can get the variable into Pages.as now but the Loader will not "reload" hen the button is clicked.
View 35 Replies- I tried, when I first started making this site, to load all of the artwork images into an array and then copy the array before resizing them for their specific functions (being seen as thumbnails or as full size pics.) Unfortunately, I ran into the well known issue of Array cloning only creating a pointer to the same group of items. I tried the newArray = oldArray.slice() trick, but it didn't seem to work. Finally, I just loaded the images twice into two separate arrays, and it works, but I hate this solution. Anyone got a better one?
- I'm trying to maintain some sort of connection between the two sets of Arrays so that, for example, when someone clicks on Thumbnail 15, Fullsize Image 15 will open up but I couldn't find anything that worked. Renaming the Instance Name dynamically didn't seem to work and adding an Instance Variable dynamically doesn't seem possible either as I can't make the Class I am working with (Sprite, in this case) dynamic ahead of time. I'm sure there's a simple method for this.opens up, the different animations seem to interfere with each other and slow each other down (they also seem to get interference from the time taken to load the image Arrays.)
Currently I have two classes which are "bullet" and "enemy".There are two instances of the enemy class.Code from an ENTER_FRAME event in the Bullet Class:

The Enemy Class has a private variable called "hits".What do I have to do in order to reduce the hits of the instance of the enemy that was hit by the bullet?
I know what instance variables, contractor methods, local variables and constructor arguments are (I think) but I'm confused as to when or how to use them, for instance I have use this a lot and I don't really understand why it is used like this...
[AS] package standard.testing {
import flash.display.MovieClip;
import flash.events.Event;
import com.greensock.*;

Why create a function with arguments...
[AS]public function tweenMe(mc:MovieClip, xPos:Number, yPos:Number)[/AS]
Then create instance variables...
[AS]
public var _mc = MovieClip;
public var _xPos= Number;
public var _yPos = Number
[/AS]
then create local variables with the values of the arguments
[AS]
_mc = mc;
_yPos = yPos;
_xPos = xPos;[/AS]
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().
How can I access instance variables in closure（inner function） for this style: this['varName']?

I narrowed the causes of an AS3 compiler error 1119 down to code that looks similar to this:
var test_inst:Number = 2.953;
trace(test_inst);
trace(test_inst.constructor);
I get the error "1119: Access of possibly undefined property constructor through a reference with static type Number." Now if I omit the variable's type, I don't get that error:
[Code]...
So what's the deal? I like explicitly typing variables, so is there any way to solve this error other than not providing the variable's type?
Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
View 1 Repliesi have an array. a random choice is made from that array.

I have the following code:
var page1:Branch = new Branch();
page1.y = 124;
addChild(page1);
I want to have the value "page1" to be dynamic, along with "Branch". Since there's a number of templates (up to 20), Branch is one of the templates. So it would be nice to use one instance creator. Also, I'm not sure how to get "page1" to be a dynamic value.
The closest to this that I've been able to find is:
star1sp.addChild(this["star"+star1Num]);
except that it doesn't fully address what I want to do. I tried adding in a bunch of "this[load_page]" and "this["page"+curpage]" to my code but had no success. I'm still on the prowl for the answer but wanted to put this out there. It's something I've tried to figure out for some time.
I have problem. I work in Actionscript 3.0. I have add Movie Clip to stage by this code:

View 6 RepliesI've just come across a problem when using the caurina Tweener for AS2. It works fine with an absolute instance name, for an object on the stage; however as soon as I try to use a dynamic instance name - it stops recognizing simple properties like _x and _y, returning this Output message:
## [Tweener] Error: The property '_height' doesn't seem to be a normal object property of menu1 or a registered special property.
## [Tweener] Error: The property '_width' doesn't seem to be a normal object property of menu1 or a registered special property.
## [Tweener] Error: The property '_y' doesn't seem to be a normal object property of menu1 or a registered special property.
## [Tweener] Error: The property '_x' doesn't seem to be a normal object property of menu1 or a registered special property.
Here is a code snippet:
ActionScript Code:
_root.currentitem = 1;
_root.xpos = 0;
_root.ypos = 0;
Tweener.addTween(["menu"+_root.currentitem], {_x:_root.xpos, _y:_root.ypos, _width:85.0, _height:85.0, time:_root.clicktime, transition:_root.clicktype});
All other tweens work fine. There are objects on the stage with instance names of "menu1", "menu2" etc.
This should be simple but I can't come up with or find the answer anywhere. All I want to do is create a series of Arrays with instance names generated on the fly. I then want to reference these later. I have a "for" loop with a variable "count" that I want to add to a base name of rowArray and use the result to create an Array. I would think that it would look something like this:
