Flash :: Reference Array Elements Of Class Inside For Loop?
Nov 13, 2011
I'm working with Flash Builder 4.5 on an Actionscript project. I've created the following classes:
package
{
public class ComplexNumber
{
[Code]....
but the code inside this loop generates the following run time error: "ReferenceError: Error #1056: Cannot create property 0 on ComplexArray." Thus, my code for "BXFN_complex[ii] = ~" is incorrect. Anyone know how to achieve what I'm trying to do? Basically, ComplexDivide.v1p0 returns two numbers, and BXFN_complex is an object containing two number arrays, and I want to assign the ComplexDivide two numbers into the ii'th element of arrays in BXFN_complex.
i have 2 arrays, a and b... in array a i have a bunch of random numbers.... now i want to loop through array a find which of the elements is the largest. for example if a[4] is the largest number in the a[] then i want b[1] = 4 and so on....
//array a full of random numbers: a[1] = 4 a[2] = 3 a[3] = 1
[code]....
so if a[4] is the bigest, b[1] will have 4 and if a[1] is second biggest, b[2] will have 1 and so on... is there an algorithm that can do this for me with an array length of X?
I have a custom class I am working on, one of the methods is:[code]Inside that function a dynamic TextField is created called txtLoaded, it is declared with [code]mcProg is added to the stage, I see the txtLoaded txt field drawn as well and I can trace properties of mcProg from elsewhere in the class but I cannot access mcProg.txtLoaded from anywhere else in the class.I imagine this must be a scoping issue, with txtLoaded only existing inside the createProgress method, but is there any way for me to be able to access txtLoaded from elsewhere in the class?
I send to the function a movie clip that I use for drag and drop, so when I drop this function is called. The problem is that of the three rectangles that I use for contain the others, only the last senses the drop target.
I have been looking to see if it is possible to force an array's elements to only be instances of a specific class. Is it possible in AS? If not could the same result be achived with my own custom object?
In simple example, I have a class called RedSquare that extends a Sprite. I need to have it in a central position of the stage. I do not know if importing definition of Stage class to RedSquare changes anything, but in the constructor of the class i could write [code]...
I'm making a sidescroller for school and im trying to get my hit test working.
I'm having trouble because I'm not sure how to properly reference an movie clip that i added in my game engine (zombie_mc), to a seperate class for my bullets the code for adding my zombie to the stage
Quote:
if (zombieTime < zombieLimit) { //if time hasn't reached the limit, then just increment zombieTime++;
Can anyone tell me why the following is taking 4 seconds for Flash to execute:
_moleHoles = new Array(); var countingMoleHoles:Boolean = true; var holeCount:int = 0;
[Code].....
There are 9 object on the stage (but this number could go up or down, that is why I'm dynamically grabbing these this way). So in my test case, this loop runs 10 times.
I have narrowed it down to something to do with the following line:
if (this['moleHole' + holeCount])
Is using dynamic (array syntax) object lookup that much of a performance hit?
I'm trying to reference the document class from inside a MovieClip that's dynamically added to the stage. I'm using this script: Code: documentClass(root).someVar; Where "documentClass" is the name of my class (duh).
This works fine, however -- when I move the class file into a folder (and make all the necessary revisions to point to the file) this doesn't work (everything else still does). I get a "not found, possibly undefined method" error. The class name is technically com.documentClass now, how do I point to that? The file is an Adobe Air file.
I've been programming with AS2 for a few years and I just made the switch to AS3. I'm hoping there is an easy solution to this problem. I have a class 'Actor' (extends MovieClip) that needs to hitTestPoint on a nested MovieClip 'root.World.walls' in a function moveRight(). The line of code looks like this: ...while (MovieClip(root).World.walls.hitTestPoint(pnt.x, pnt.y, true)) {... But I keep getting various errors when I try different solutions.
I am quite new to AS3 and I am having trouble adapting my knowledge of Java to this new language i am trying to make a simple grid in which i could work on each individual square seperately(changing their colour for example). To do so, I created a 2D array,hoping it would allow me to work with some kind of coordinates system. I initialised the array using while loops and for some reason, this does not let me access the array outside the loops.[code]The two last lines are causing the problem, instead of turning the last square red, they return the following error: TypeError: Error #1010: A term is undefined and has no properties.However, when placed inside the loop, there is no problem and the whole grid turns red.
I have a class consisting of a nested array called twoDArray.
public class TestArray { public function TestArray() { var twoDArray:Array = new Array(new Array("one","two"), new Array("three", "four")); }
[Code]...
I thought I would be able to reference OrbArray for example using trace(OrbArray[0][0]); giving me the output I am looking for of "one". When I attempt this I get ReferenceError: Error #1069: Property 0 not found on com.orbclasses.TestArray and there is no default value.
Ive got two classes and my stage. I'm trying to use an array to keep control of my enemy class's number for collision purposes and I managed to get the enemies to populate the array.
I am now trying to make it a class. It appears to work except I only get the last item in the array. Not sure how to fix. colorHolder_mc is added prior to the loop.
i have a bunch of variables in use in this secondary class, simplify this using a loop. would like to name the variables, push into the array and have the array available from the parent class
I'm working right now on a map generator. I stumbled on a very annoying problem. I'm using the for loop to add the map elements on the stage. But when the "forest" area begins to be to thick all trees begin to overlap.
I'm trying to loop a f4v but I keep getting an error. I have imported a f4v into my library and I now have a FLVPlayback in my library. I have added this to the stage and named it "video_test". I have added the below actionscript to my timeline:
Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:
stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)
I am trying to set up a script that will generate a matrix repeating the same symbol X by Y times. For example, b(3,2); should generate...
OOO OOO
...and after many days of being tested by this problem I have narrowed the location of my problem down to what can be seen up in the following.
Code: for (a=0; a<4; a++){ for (b=0; b<4; b++){ var z:Number = ((a*4)+b); _root.attachMovie("Light", ("L" + z), _root.getNextHightestDepth(), {_x:(a*45), _y:(b*45)}); } }
For some reason, that loop will only attach one copy of my "Light" movie. I cannot seem to figure out why more are not added. I am putting that code on the first frame of my movie. There is nothing else in my project yet.
getChildByName("name") works great if my object has been added to the stage or some MC. But what can I do if I have an object created dynamically that I want to reference later in the code but haven't added to the stage? Here's an example:
for (var a = 0; a < 10; a++) { var testObject = addChild(new BlankMC()); testObject.name = "myTest_" + a; }
[Code]....
This returns my BlankMC instance, but ONLY because it was added to the stage. If I don't use "addChild", then I get "null" because my instance is not a child of the stage (or anything else as far as I know). Is getChildByName the ONLY function for referencing a dynamic element?
I am doing a looping background with 2 identical BG movieClip (B1 and B2). Those 2 are "new" by the same class.
var B1:MovieClip = new BG(); var B2:MovieClip = new BG();
But because this BG class picture is loader from the internet and the picture is rather big. When I addressed its loading by using progressEvent. The picture is really loaded 2 times. Is there anyway I create B2 based on B1 without using new BG() again? Since it definitely makes a new BG with Loader code inside.
Is there any documentation link where I can find list of styles applicable to flex controls? In particular the AdvancedDataGridControl. Like border, border-left,top,bottom,indent, etc like list of all possible style elements.
#1: Link provided by Lior below is the complete list. #2 : found this looks quite cool.
I would like to dynamically create elements based on the array. I would like to just put the array name and append _panel. so menu_item_panel will become settings_panel, info_panel,etc. I cannot figure out how to do that?
