searching a multidimensional array

19 posts in this topic

Hey everyone

First of all, I know it's probably against the rules, as it's for a game BUT it's not a tool to make the gameplay itself easier.

I wrote a script that loads weapon file to arrays and then displays stats of every weapon, I want to release the code on the official forum, as many people ask for stats of certain items.

the script reads one line of the file at a time and creates an array from it with "," delimiters. 

then the script searches for the right item name in $array[1] (0 = index, 1 = item name) and when the index is found it returns the $i from the loop, which is the line in the file, and then reads the line and parses it. 

My only problem is that it's extremely slow, it takes like 45 seconds to reach an index that is located deep in the file.

is there a way to make it search faster?

here's the searching piece of the code:

#include <file.au3>
#include <array.au3>
$searchindex = inputbox("Search","put the name you're looking for")
if $searchindex = "" Then
    Exit
EndIf
$file = "itemweapon.csv"
$lines = _FileCountLines($file)
$i = 1
progresson("Searching","Searching for "&$searchindex)
do
    $percentage = $i/$lines
    $percentage = $percentage*100
    $percentage = round($percentage, 0)
    progressset($percentage, $percentage&"%")
    $sr = filereadline($file,$i)
    if @error Then
        msgbox(0,"Error","Unable to open the file")
    EndIf
    $searcharray = stringsplit($sr,",",2)
    if $searcharray[1] = $searchindex Then
        exitloop
    EndIf
    $i = $i+1
until $i = $lines
progressoff()

once again, yes, it is for a game, but it's not a tool that will ease the gameplay in any shape, sort or form. People often dont know the stats of certain items and need to figure out the stat indexes and so on. 

if you believe it's inappropriate, please close the thread or delete it.

thank you

I have a question, why even mention it's for a game?

why lie it's not when it is? I dont feel like making up excuses.

thanks for your reply :)

It's not lying, it was just code you need help with.

But now, it's game automation.

 

well if you put it that way, I guess I'll have to figure the issue out myself.

thanks for your reply :)

Tioner,

 

why even mention it's for a game?

Because having been a member here for over 2 years you seem to have missed the fact that using the "G" word here is like a red rag to a bull. So as the question has absolutely nothing to do with the game and is actually about searching arrays, why even mention it? :huh:

But at least the thread can stay open. :)

And I suggest reading the file into an array with _FileReadToArray and using _ArraySearch. Your current code is horribly inefficient as by using an index with FileReadLine you are re-reading the whole file each time. ;)

Post sample itemweapon.csv.

It isn't game automation at all since it only interact with a passive data file regardless of game running or not.  <-- just like Melba23 found.

thank you for your reply, I will try your code as soon as I come home. 

I tried to analyze it, and I cant figure out what StringRegExp does, docs have a huge chunk of information about it, but I want to know what exactly the "(?m)^d+,.+? ,.*" part does. 

is there a chacne you could explain this to me?

The pattern means:

(?m) input is multiline

^ anchor to start of line

d+ one or more digit(s)

, followed by a comma

.*? the shortest sequence of characters which don't cause the remaining of the pattern to fail

 , followed by a space and a comma

.* the remaining of the line up to but not including the newline sequence

In short this regular expression captures a line which contains the search term in the second .CSV field.

I've forgotten to make it insenvitive to case. It can surely help, so make that pattern "(?im)^d+,.+? ,.*" where the (?i) option is included.

thank you for your reply, I tried your method but it didnt work (I probably messed something up)

however, I made it much faster by reading the entire file, then split it into arrays using @CR delimiter, and then split each array into another bunch of arrays to search through. it gives the positive result in around 2 seconds now :)

if anyone wants to take a look at the code - here it is:

#include <file.au3>
#include <array.au3>
$searchindex = inputbox("Search","put the name you're looking for")
if $searchindex = "" Then
    Exit
EndIf
$file = "itemweapon.csv"
$lines = _FileCountLines($file)
$ff = fileread($file)
$i = 1
$array1 = stringsplit($ff,@CR,2)
progresson("Searching","Searching for "&$searchindex)
do
    $arraytosearch = StringSplit($array1[$i-1],",",2)
    $percentage = $i/$lines
    $percentage = $percentage*100
    $percentage = round($percentage, 0)
    progressset($percentage, $percentage&"%")
    if $arraytosearch[1] = $searchindex Then
        ExitLoop
    EndIf
    $i = $i+1
until $i = $lines
progressoff()
$line1 = filereadline($file,$i)

thank you again for your help - reading the entire file at a time was the way to go :)

Oops, I'm sorry, I pasted the wrong code!

#include <file.au3>
#include <array.au3>
Local $searchindex = InputBox("Search", "put the name you're looking for")
If $searchindex = "" Then
    Exit
EndIf
Local $file = "itemweapon.csv"
Local $csv = FileRead($file)
ConsoleWrite($csv & @LF)

Local $aLine = StringRegExp($csv, "(?im)^\d+," & $searchindex & " ,.*", 1)
If @error Then
    MsgBox(0, "Error", "Unable to locate item")
    Exit
EndIf
Local $array = StringSplit($aLine[0], ",", 2)
_ArrayDisplay($array)

Please try with this one and report. It should definitely be faster.

I tried it, Holy crap it is fast, it returns the value pretty much instantly!

hmm I tested it a bit, it returns values MUCH faster than the other method I used, however it sometimes returns error 1

Ah! (I'm not surprised by the power of a simple regexp)

Sorry, I kept a previous capture in the clipboard and the actual code was left in SciTe. Good to see it works for you now.

Help file on StringRegExp will tell you (almost everything).

Use this site to practice by selecting PCRE favor of regexp engine.
