I am trying to remove an element from an array by using splice like:
Code:
myArray[1].splice(2,1);
This works & finds the element I am looking for but it doesn't really remove the element but it will just insert a blank object instead. Am I doing something wrong here. How would I "really" remove the element, meaning that the Array would become shorter?
[Code]....
so my array is longer but u get the point. i want it to whenever i click on any letter, cause they are all on buttons, the one i clicked dissapears. i dont know how to work splice with the "i" variable,
I have an array used to track shots fired from a cannon, and when they hit the ground they are removed.
I would like to know what is the most efficient way of finding and removing a certain element from an array. I heard that using pop() instead of splice() was faster, is it ?
Also, the big question I have is that the only way I see of actually finding the element in the array is using
Code:
for(i=0;i<array.length;i++){
if(array[i] == movieClipToRemove){
//i == movieClip index in the array
}
}
Then I would use either splice() or pop() to remove it from the array before deleting the MC. Is there a better way than scanning through the whole array comparing each element to the triggering MC ?
how to remove a particular element from array
View 1 RepliesI have an array of objects. Each object has a property called name. I want to efficiently remove an object with a particular name from the array. Is this the BEST way?

First of all, how should I remove an element from an array?Now I am using arrays this way (just an example):
array["red"] = 0xff0000;
array["black"] = 0x000000;
How do I remove "red" for example from the array?
i have items drawn my stage dynamically and information regarding them in arrays.when i remove an item from the display list:Code:a.target.graphics.clear(); then use the spliceď and index of method to locate chosen MC remove their values from specific array :Code:mcName.splice(mcName.indexOf(+mcRef.boxCount),1);Now when i remove any item which isnt the lastitem of the array, then trace all the data of the array using a loop the values appear to have corrupt? like they have lost the order in the array since one was removed?
View 21 RepliesUsing a for-loop I made a grid of movieclips. But I wanted it so every second row had one less than the one above it. I thought I had that sorted when I placed an if statement in the method. However, flash still "sees" the missing movieclip. I've tried to splice the array element from it, but instead of removing it, it seems to have copied it.
Here's the code:
Code:
package

import flash.display.MovieClip;

How can i remove the element from array in actionscript? i have this array: myArray = new Array ("1","2", "3", "4", "5"); i want to remove the element "3" when i press button.
View 3 RepliesI am trying to remove elements form an array. The array is kind of special: content depends on what you have clicked or not:
Code:
pArr = [];
for(var i =0;i<max;i++){
johndoe[i].pressed = false;
johndoe[i].onPress = function(){
this.pressed = !this.pressed;
if(this.pressed){
pArr.push(this.obj)
}else{
pArr.remove(this.obj);
}}}
Of course the remove function is my pb, not done yet. How can I remove the same object from the array, knowing that the array can contain several times the same object, so I do not want to delete it many times but just the good one? So the trick is to remove only the object associated with the johndoe button. Maybe the pb comes from the way I push the elements?
Is there a way to generically remove an object from an array? (maybe not using array.filter or creating a new array)
Example:
var arr:Array= new Array();
//create dummy objs
for (var i:uint=0; i < 10; i++){
var someObject:SomeClassObject = new SomeClassObject();

Here's what I'm currently doing/trying to do to accomplish my goal. But it is not removing the "row" the way I would like it too.
So, I'm making an object, then pushing it into an array. And the adding to the array part works fine and just as I expect.
var nearProfileInfoObj:Object = new Object();
nearProfileInfoObj.type = "userInfo";
nearProfileInfoObj.dowhat = "add";
[Code].....
But this doesnt seem to be deleting the whole row like it implies.
From what I know the whole idea behind having collection classes is introduce extra wrapper methods which will be handy for developers.
Then why does ArrayCollection in Flex not seem to have some methods that array has.
ArrayCollection does not have a copy, concat, join or splice methods which return a new array so we need to do the copy manually?
Currently my code is this[code]...
What I am trying to do is splice the array at the right time in my code so it will disappear from my array- and the affect would be the returnRandom() function won't return that same item ever again. [url]...
Is it me or the indexs in the array are not valid after using splice?
Code:
var arr:Array=new Array(3);
arr[0]=porsh;//car objects..not implemented here just for exemple

I am working on a basic game in order to practice my AS3 coding skills. The point I am at is that when my enemies (Falling vertically down) touch the bottom of the stage I want to make all enemies in all of my arrays be removed. Now, the code below works perfect for that description of what I want, but it does not remove everything at the same time. Instead it does not remove all of them at the same time, and it's very noticable. As in there is about a 3-4 second gap between when the first dissapears and when the last does.
So will I need to completely optimize my entire project, or is that any way I can do this process that is more efficient? Also what are your thought on just changing all of the enemies y coordinates to -100 or something at first, and then removing them while they are off the stage?

it deletes all the items but 1. I allways have one item left wich should be deleted but it isnt.
is array.splice equal to displaycontainer.removechild?
View 1 RepliesI have an unordered ever-changing array that looks something like this:
12,23,1,4,11
I just want to basically tell the code to remove a specific item, let's say "23". But since the array is constantly changing length, I can't use splice.I also can't have any gaps, such as "12,,1,4,11". It must return "12,1,4,11".And on a related note, can I then check if this array has the same content of numbers as another array (and do I have to put them both in numeric order before it can perform the check, or doesn't it matter that they're not in the same order, as long as they have the same contents)?
I am trying to replace an Object inside my nested array (colArray) by using splice, the object acts as my player and will need to maneuver around the Array it's in. The Problem is splice doesn't appear to be showing anything in return, it comes up with an error saying: Cannot access a property or method of a null object reference.What am i doing wrong ? And how would i go with moving my playerObject around the array?
var gridContainerMC:MovieClip = new MovieClip();
var gridSize:Array = [col,row]; //Rows, Columns
var gridArray:Array = new Array();
var col:Number = 44;

I have an array with many values pushed into it (happen to be names of objects). I am using a for loop to check all of the objects (by index number) for collisions, etc. Periodically, depending on a condition, I want to remove the currently checked object's name from the array list. I noticed that there is a problem if I immediately splice the checked name from the list. Namely, the list gets shorter, which is what I want, but not until I'm done checking all objects. Is it a good idea to solve the issue by incrementing i-- after the splice? I do this so that the object that used to be next in the list doesn't get skipped.It seems to work very well but I want to know if this is a lame/problematic solution and if there are any better ways of dealing with it
for (i=0;i<myarray.length;i++){
var ob=myarray[i]
//any old condition

I have a drag and drop game. You listen to a sound for exampl "bread" You proceed to drag that mc to a box. If it is the right object I want to remove that mc and splice the array so it doesn't choose that object anymore. However I have notices two things.
When I splice(0) a specific element - then nothing works. When I splice the cuurent indexed element ie: the last element to get right - it doesn't actually remove it from the array. I have highlighted the key code parts.

Is it possible to, if you have an array of class names like ActionScript Code: var city01names:Array = ["pic_01", "pic_02", "pic_03" ...] make a new array which would read these names, instantiate them, and push them into a new array containing the instances of all these pictures, which I could then use for a slideshow?

I have an array called dropTarg1 which stores dropped-in items.I want to loop through this array and in a textfield, display each array item on a new line of this text fieldI think I need to use something like Array.join("/n") but I can't get it working properly. I hope that the /n would create a new line of the text field called reviewBoxContentText.
for(var i:Number = 0; i<dropTarg.length; i++){

How do I remove the last element in a arrow?
I have an arrow called lagers.
When I press a button I want the last element in the arrow to be removed.
I heve tried this code, but I cant figure it out.
removeMovieClip(lagers[lagers.length]);
I have 4 buttons and an empty array. When a button is clicked,I'm adding a element to an array with array.push. However, I want to check the array 1st to see if that element exists. If so, then don't add it. Here's what I have thus far
[Code]...
Now I'm taking it I'd have a conditional statement to see if the element already exists. Unfortunatly I cannot just disable the button. I searched the AS dictionary but oddly enough it doesn't have an easy way to search an array. And IndexOf seems to only work for a string.
I am wondering how to remove a specific element from a vector.[code]...
So from the code example above I was using Element.pop() but thats wrong -I think -as it removes the LAST element. I need to remove the element at the location of the match.
