[SOLVED] randomly change an array

Recommended Posts

Posted (edited)

Hello,

I'm trying to randomly change some cells in a array on a given percentage.

at this point I 've a array whit all 0's and want to change some cells to 1.

I'm not shure how to do this in a good coding sort of way.

Also maybe there is a build in function whish I'm not aware of.

Does somebody know how I can do this in a easy way?

I was trying to get the total count of cells and get the percentage of it.

And was stuck when i wanna change the cell.

please advice, thanks in advanced for your help.

#include <Array.au3>
Global $percentage = 0.2
Global $aArray[Random(10,30,1)][Random(10,30,1)]

   For $x = 0 To UBound($aArray,1) - 1
      For $y = 0 To UBound($aArray,2) - 1
         $aArray[$x][$y] = 0
      Next
   Next

_ArrayDisplay($aArray)

randomize()

_ArrayDisplay($aArray)

Func randomize()
   Local $total_to_change = ((UBound($aArray,1) * UBound($aArray,2)) / 100) * $percentage
   ConsoleWrite( "$total_to_change = " & $total_to_change & @LF )
   ConsoleWrite( "total in array = " & (UBound($aArray,1) * UBound($aArray,2)) & @LF )
EndFunc

FMS,

Use Random to set the array elements to 1 or 0 as you create the array:

#include <Array.au3>

Global $percentage = 0.2
Global $aArray[Random(1, 10, 1)][Random(1, 10, 1)]

_ArrayDisplay($aArray)

For $x = 0 To UBound($aArray, 1) - 1
    For $y = 0 To UBound($aArray, 2) - 1
        $aArray[$x][$y] = ((Random(0, 1) < $percentage) ? (1) : (0))
    Next
Next

_ArrayDisplay($aArray)

      So Im trying to make a simple 2d game and make some sort of collision detection so why not to make a 2 dimensional array but i have no clue how  to write it in multiple lines
      Global $map[5,5] = [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0] something like this but it doesn't work
    • Zein

      #include "..\Include\Array.au3" #include "..\Include\File.au3" #include "..\Include\AutoItConstants.au3" Local $aRetArray Local $sFilePath = "n.csv" _FileReadToArray($sFilePath, $aRetArray, ",") ; _FileReadToArray($sFilePath, $aRetArray, $FRTA_COUNT, ",") _ArrayDisplay($aRetArray, "Original", Default, 8) The above code shows two versions of _FileReadToArray and both don't work as expected.
      The first one doesn't use the comma as a delimiter. (so I get a single column array)  I tried adding "Default" between $aRetArray and "," then it told me it had an incorrect number of parameters. 

      I looked again at the documentation:
       
      #include <File.au3> _FileReadToArray ( $sFilePath, ByRef $vReturn [, $iFlags = $FRTA_COUNT [, $sDelimiter = ""]] )
      And I with or without the flags params I should be getting a 2D array due to my file being a csv. 
      I then tried a regular flag, $FRTA_COUNT, and it tells me that I'm using a variable $FRTA_COUNT while it's not declared. Tried putting in 1 instead and it told me again, incorrect number of params.

      Hi,
      Recently I have had the need to do a sort and then do a second sort while the item of the first sort stays the same ( double sorting , first on column x then while column x is the same sort column y).
      I did not put much efffort into error checking but so far I did not need it.
      For my applications so far it works perfectly however if someone is willing I want to test this extensivly.
      If anyone has big lists of random stuff to sort could you try this out please?
      #include <Array.au3> ; #FUNCTION# ==================================================================================================================== ; Name ..........: _ArraySort_Double ; Description ...: ; Syntax ........: _ArraySort_Double (Byref $array[, $first_index = Default[, $second_index = Default[, $ascending = Default]]]) ; Parameters ....: $array - 2d array to sort. ; $first_index - [optional] first column to sort.

      So I've made this script that detects how long i have held down my left mouse button for and stores the information in an array and then sorts its using _ArraySort but the output is half sorted half broken.
      Here's my script:
      HotKeySet("{F1}","_exit") #include <Misc.au3> #include <Timers.au3> #include <Array.au3> Local $dll = DllOpen("user32.dll") $on = False Global $array[0] While(1) If _IsPressed(01,$dll) Then $timer = _Timer_Init() While _IsPressed(01,$dll) Sleep(1) WEnd $time = _Timer_Diff($timer) _ArrayAdd($array,"Time: " & Floor($time) & " ms") ;~ ConsoleWrite("Time: " & Floor($time) & " ms" & @CRLF) EndIf Sleep(50) WEnd Func _exit() _ArraySort($array) _ArrayDisplay($array) Exit EndFunc And the output:

      See how its not sorted?  What is the problem here?

      Hi guys,
      See attached for an array example.
      to simplify what i want to achieve,  I want to split this array into 9 different csv files.
      the first file would contain the list of "key" and the corresponding "ID1", the second would have "key" and the "ID2", the third would have "key" and "ID3"
      However, I want to remove all the rows that don't have an ID recorded in the respective ID2, ID3 4...5...6 etc, so the file only contains row items with a key and the ID.
      Would be the best way to loop through the rows and delete the row if the array field is blank - would I then need to repeat that row ID to check that the row that its replaced is also empty (ie the one after the one I just deleted)? I see this getting messy.
      or _arraySort, and delete everything below the last filled row? <-- this might be best?
      Or should I use the excel UDF, apply a filter (not selecting the blanks), then create/export to the array->csv?
       
      Super keen to hear your thoughts.
      thanks!
