Optimization :: Search Difference Between Array / List Of Object?

Mar 17, 2012

Premesis:I am using actionscript with two arraycollection containing object with value to be matched...Let's assume I have two list of elements A and B (no duplicate values) and I need to compare them and remove all the elements present in both, so at the end I should have

in A all the elements that are in A but not in B

in B all the elements that are in B but not in A

now I do something like that:

for (var i:int = 0 ; i < a.length ;)
{
var isFound:Boolean = false;[code].....

I cycle both the array and if I found a match I remove the items from both of the array (and don't increase the loop value so the for cycle progress in a correct way).I was wondering if (and i'm sure there is) there is a better (and less CPU consuming) way to do it...

Arrays :: Search Multidimensional Array (Flash As3) Using Another Array For Search Criteria

Sep 26, 2011

Long story short: I want to search a multidimensional array in AS3 for (in this example) the location of 6 strings - all of which are stored in another unrelared array. Long story long: Once I get the locations (in the multidimensional array) of each string, i then know where it's located, and can access other atributes of that object - so if i found the string "box3" is located in element [5] of my multidimensional array, i can now target: multiArray[5][3] to return the 4th item stored (keeping in mind we're starting from 0, so 3 is the 4th position).

I can get this to work once, but I'm trying to set up a for loop based on the length of my basic string storage array - this array holds (in this example) 6 instance name strings - each time my for loop loops, i need to run a search in my multdimensional array for the next consecutive instance name. Then, once I've located all of them (and store the results in a new temporary array) I can dig around in each location for the info I need.

Actionscript 3.0 :: Optimization Of HUGE List Comparison: Dictionary?

Apr 8, 2010

I'm on the brink of finishing the first iteration of my first game ever o/ and of course the last item I need to complete is the hardest. I am making a simple word game, and all details aside, the task at hand is a conditional block to determine whether the word the user has entered is real, and in order to do this I need to somehow compare it to a dictionary list.

1 hour of research has quickly opened up an entire universe of data structures, open source xml documents, people willing to take my money for spell checkers, and of course RegExp which I have no experience using (but am willing, and wanting, to learn!). One of the main problems Google is giving me is the addition of the Dictionary class in AS3, which "lets you create a dynamic collection of properties, which uses strict equality (===) for key comparison on non-primitive object keys..." So finding previous literal dictionary uses is tough.

I soon found taking a dictionary txt file (118619 lines) and converting it line by line into an array takes 3 minutes on my beast of a laptop gaming rig (Asus W90), and while I knew this was a bad idea, it was a nice learning experience (to give me a gauge of processing abilities).

I am wondering whether using XML is an appropriate alternative, or if there is a way to externally access a dictionary somewhere online. Looking at the XMLList Class available I see text() and toString() methods; yet I still see heavy iterations in accessing the dictionary.

Which brings up the next point: easiest way to find a String match. I understand that comparing each word one by one would be tedious for the program, so maybe splitting up the list by letter (or maybe string length, looking at the file), or first and last letter.

My question, is there any difference to declare each array as such, before pushing them to the main array? trace(arr[0]);// i know it traces the arrays contents, but if it could, would it tell me this is data type Array , exactly the same as if i had declared it?

Nov 4, 2009

what i would like to do is create a search field that as the user types in the search bar if there are any matching entries in the list, the focus/selection jumps to that particular item in list. i don't want to clear the list just go to the item that matches.i would like it to be predictive so if i have these entries:and the user types "s" in the search box to the first "s" entry in the list (samson) is selected, if they type "se" the selection jumps to the first entry with "se" in it (seek) if they type "seet" the selection jumps to "seether" and so on.i have absolutely no idea how to do it, but more importantly...is this possible?

ActionScript 2.0 :: Get Input Text To Search A List Of Words?

May 1, 2011

I'm planning to make a game that gives players the choice to search a word when selecting a character, and if that word is found, they get to play as them. I don't even have a clue what, where and how I am gonna put the list in the game for something to search it. I'll try to give an example:

A user puts "horse" into the input field, presses the "Search" button, and Flash searches the word "horse" in a list of maybe 30 or so words. If it returns no results, a message says, "keyword not found". If it is found, a picture of a horse comes up in the character preview box.

ActionScript 2.0 :: Keep Choosing An Ingredient From The List Array Until It Finds A Value Thats Not In The Preview Array

Jul 31, 2009

I'll start by posting my code then explain what I want it to achieve.

[Code]...

What I am attempting and failing to do after much trial and error is to have a random ingredient from the ingredientList array pushed into the previewIngredients array making sure the new value going in is not already in the preview ingredients array. If the same value is there I want it to keep choosing an ingredient from the list array until it finds a value thats not in the preview array then push that one in there. It feels like I'm getting close but obviously I'm either going about it the wrong way or just missing a little somthing somthing out.
