I want to write a function which removes elements from an array of integers starting from the lowest values without changing the positions of the elements. Programming language is ActionScript3.
[Code]...
I know Array.NUMERIC and Array.DESCENDING would change the position of the elements, but I can't seem to figure out the logic on how to keep their positions.
Example:
var arr_1:Array = new Array();
arr_1.push({sdate:"2010-02-02",status:"New"});
arr_1.push({sdate:"2010-02-03",status:"New"});
arr_1.push({sdate:"2010-02-04",status:"New"});
arr_1.push({sdate:"2010-02-05",status:"New"});
How can I change element number 3 status to: "Old", without removing it. Just update the status value??
how do you find out in which position a certain value is in an array?
View 9 RepliesI have an input text field that is named in the properties box as 'numberOfKids'. When the program is executed, and a delete or backspace is pressed the input textfield goes blank and any calculations that use 'numberOfKids' shows NaN.I have trapped the NaN and undefined so that a numeric 0 shows up instead of a blank.
First problem: The cursor is to the left of the zero, so the first number inputted by the user is 10x larger than what they want. 0 becomes 10. How do I get the cursor to move to the right of the 0?
Second Problem: When I manually move the cursor to the right of the 0 and input a number, say 4, it shows up as 04. How do I delete the leading numeric zero in the input textfield?
Here's the code I am using:
calculateChildWeight = function () { if (isNaN(numberOfKids)) { numberOfKids = 0; } if ((numberOfKids) == undefined) { numberOfKids = 0; } if (numberOfKids>=0 && numberOfKids<=137) { numberOfKids = numberOfKids; } else { numberOfKids = 0; } if (isNaN(adjustedChildWeight)) { adjustedChildWeight = 0; } if ((adjustedChildWeight)=undefined) { adjustedChildWeight = 0; } adjustedChildWeight = Number(numberOfKids*(-100)); //numberOfKids.setSelection(numberOfKids.length, numberOfKids.length); //if (numberOfKids.length=2 && numberOfKids<10) { // remove the first character or leading zero// numberOfKids = numberOfKids;// }};
Is it generally to position elements relative to other elements or in absolute values?
View 2 Repliesdoes anyone know how to shift all the array elements by one or more without deleting the array itself?
Something like rotating the array:
1,2,3,4,5,6,7,8,9,10
10,1,2,3,4,5,6,7,8,9
9,10,1,2,3,4,5,6,7,8
8,9,10,1,2,3,4,5,6,7
7,8,9,10,1,2,3,4,5,6
I added a Menu_mc on my stage. Initially, this should be at the center of the stage and when I click on it, it will tween on the upper left corner of the browser. However, when I resize the browser, the Menu_mc goes back to the center of the screen.
I have tried separating a different actionscript file where it is specifically for initialization of the object and another one for resizing. And then when I call it on my main AS file it goes like this:
Code:
// Add the symbols to stage
var Menu_mc = new Menu_MC();
addChild(Menu_mc);

But it seems futile.
I've run into a new problem, this time with positioning. I've narrowed down the line that's causing it--"block.y = block.y + block.height;" in SetOfBlocks.shiftDown. When I take it out, no problem. But with it in, instead of just dropping each block down by a block height, the affected blocks sometimes move up, and also often move about randomly within the X axis--although their new positions always keep them lined up with the 'grid', which is to say, within multiples of the block height and widths.

I thought i'd start this thread to uncover peoples habits and practices when it comes to the simple operation of adding and removing elements on stage. I ask because there are so many alternatives, and I keep wondering what might be the best/most eficcient way of doing it. Let me explain by giving an example:
Your user has chosen to click that flashing button that says "Sign up for our mailing list" and you need to prompt the user for a valid e-mail address by presenting him/her with an alert box on top of everything else. Do you.[code]....
Ive just finished the foundations on my flash site.. each button directs to each area etc etc.The way I have structured my buttons is as follow,[code]so basically if I click on a button Im not at already, the elements from the current section are removed from the stage and im directed to the new section.This works fine for simple objects like shapes and text but some of my sections have custom scrollers and functions and this is where I've run into some errors.If I remove from stage and set to null like I've been doing, everything still works fine, but my output window complains off null object references ? If I remove from the stage but dont set to null my functions stop working and I get an error stating the displayobject must be a child of the caller ?

Is there a way to write out an array without the that separates the elements in the array?
View 15 RepliesIf I am a subclass of an Array, how do I access an element?
class ArrayOfFoo extends Array
{
public function getFooAt(anIndex : int) : Foo
{
return this[anIndex] as Foo; // <---- looks for an object attribute (named "0", for example)
}
}
I could wrap an array instead of subclassing it, however lacking a universal IArray interface, that is less than useful for standard and custom functions expecting an Array.
I have a stand alone projector file that I am working with. I am trying to figure out how to position certain elements at the top, bottom and sides of the frame so that when the projector is viewed on different machines those elements will remain in the same position.
The file I am working with will be full screen and I have figured that part out. But I need to create a navbar for the top and another bar at the bottom of the screen. If you look at the drawingart site and you resize the browser all the elements stay the same size too. I need to achieve this effect as I am creating this file to work on all size screens.
I've been playing around with the presentation screens and slide in Flash, from browsing the web there seems to be very little if any information of how to control MC's within different parts of a presentation i.e. removing them or changing alpha. I've loaded an MC and now I'm am trying to remove it from the stage been experiment on the same slide and I just cant seem to get control of it.
I was using
_root.slide1.intromc._alpha = 0;
But this doesn't work for. How I can get access to MCs in a slide if its possible !!!!
I've written the following method (in actionscript 3, it's a flash application) which returns what transformation type is required for the current mouse position in relation to a given element position.

when i run get lastIndexof for an array I get returned the the size of the array instead of the position here is the code:[code]but instead of returning the last index of it before the current index, it returns the current index (or jus the array length). help!!! it is my first time using lastIndexOf so I am probably using it incorrectly.ps this does not include some of the function run (i know i am passing a value which it does not look like i am using, but i know that part of the code works)

I am making a dragable map and there are few thing on top of the map(UI). When the map is double clicked it enables drag. But it's changing the index position, basically, it going over the UI. what's the easiest way to control the index position of the map? The click and drag event is controlled in mapZoom class.

I know I can horizontally flip an image using ActionScript Code: image.scaleX *= 1;
However, this seems to move the left border of the image past its x coordinate.
I would like to make sure that the image stays within the same borders as before and that (x,y) is still the top left corner. Short of wrapping it in another image, is there a way to do that?
