loops in loops?

[szucsaaron]

Hi!

I was wandering if i could make a script where there are like:

While 1
...
While 2
...
Wend
...
Wend

Please reply!

You can do that, plus to exit a loop look at ExitLoop.

[szucsaaron]

so shall it look like:

While 1
...
While 2
...
If ... then
Exitloop
Endif
Wend
Wend

or you could add the condition to the while loop itself

While $X = 0

If ... Then $X = 1

Wend

Yeh, it just depends what you want to do.

[szucsaaron]

or like this?

While 1
While $X = 0
If... Then
$X = 1
EndIf
WEnd

Yea if you wanted, might want to add a sleep so dont you hog the cpu

While 1 ;Main Loop

sleep(250) ;Not to Hog Cpu

     While $Variable = 0 ; Secondary Loop and Condiction

     sleep(250) ;Not to Hog Cpu

          If ... Then ;Your code
          $Variable = 1 ;Breaks Secondary Loop and Returns to Main Loop
          Endif

     Wend ;End for Secondary Loop

Wend ;End for Main Loop

or

While 1 ;Main Loop

sleep(250) ;Not to Hog Cpu

     While 1 ; Secondary Loop

     sleep(250) ;Not to Hog Cpu

          If ... Then ;Your code
          ExitLoop ;Breaks Secondary Loop and Returns to Main Loop
          Endif

     Wend ;End for Secondary Loop

Wend ;End for Main Loop

Thanks for help it was really helpful!

Just to explain how "While <expression>" works: The expression is evaluated and the loop executed as long as the result of the evaluation is True. If the expressions is set to 1 it's the equivalaten of True, thus creating an infinite loop.

You could write:

While 1
    While 1
        If ... Then ExitLoop ; Exit inner loop
        ; Your code for the inner loop (e.g. process the 2nd dimension (columns) of an array ...)
    WEnd
    If ... Then ExitLoop ; Exit outer loop
    ; Your code for the outer loop loop (e.g. process the 1st dimension (rows) of an array ...)
WEnd

In witch cases we get hog the cpu ?

When we put a lot of whiles/loops etc.

Thanks water

While 1
If ProcessExists("AutoIt3.exe") Then ConsoleWrite("A")
WEnd

Uses 25% Cpu of this 2.40 GHX Quad Core CPU

While 1
Sleep(10)
If ProcessExists("AutoIt3.exe") Then ConsoleWrite("A")
WEnd

Uses 12% CPU

While 1
Sleep(250)
If ProcessExists("AutoIt3.exe") Then ConsoleWrite("A")
WEnd

Uses 0% CPU

Now unless the script needs Real-Time Responses, 250 is 1/4 of a second which in most cases is more then enough while keeping the CPU usage low.

In my view, when coding something script performance is very important. More so if your script is going to run on lots of or other machines, as maybe not everyone have the same gaming rig as you.

Well IanN1990 the explanation can not get better..

Thank you my friend..
