TimerDiff behaving weird

Recommended Posts



I found my mistake and the script works fine now.

But now I have another problem:

The script works fine with 'send' in e.g. my browser but not in the program I need it.

I already tried using 'controlsend' but that did not work either.

What else can I try?




Hello there,


I just started using AutoIT and I discovered a problem with TimerDiff.

What I want to do is a script, the emulates pressing the spacebar for me in a userdefined intervall.

This intervall is supposed to also be defined by the spacebar.

With Backspace I can stop the emulation of the spacebarpresses and Enter closes the script.

My problem is:

TimerDiff gives out strange, extremely high values.

Where is my Mistake?

MsgBox(0, "BPM Tapping", "Das Programm BPM-Tapping läuft jetzt")

HotKeySet("{SPACE}", "TapFunktion")            ;Funtion that is Used to get Time between Button presses
HotKeySet("{ENTER}", "Schliessen")             ;Function to exit the script
HotKeySet("{BS}", "TapStoppen")            ;Function that stops the 'Button press algorithm' from doing anything

Global $TapAn = 0
Global $wieoft = 0
Global $Timer
Global $Diff

While 1
   while $TapAn = 1                         ;Space is presses every Diff milliseconds

Func TapFunktion()
   if $wieoft = 0 Then                      ;when space gets pressed first time
      $Timer=TimerInit                      ;Timer starts
      $wieoft = 1                   ;Number of spacepresses set to 1
   ElseIf $wieoft = 1 Then                  ;in the second cycle
      $Diff = TimerDiff ($Timer)                    ;the timedifference to the first spacebar press is taken
      $TapAn = 1                    ;the 'button press algorithm' goes active
      $wieoft = 0                   ;spacebar presses set back to 0
      MsgBox(0, "Test", $Diff)              ;msg Box I made for debugging because of strange behaviour

Func TapStoppen()                   ;stop the loop
   $TapAn = 0

Func Schliessen()                   ;exit
   Exit 0

Simple test code like this works like it's supposed to do:

$begin = TimerInit()
MsgBox(0, "Timer", "Duration = "& TimerDiff($begin))

And what program would that be? :huh:

Might I suggest reading the Forum rules (there is also a link at bottom right of each page) before posting again. Not suggesting that is what you are doing, of course - but as this problem is so often caused by anti-automation measures within games it might well be the reason. ;)

@mikell Thank you, I needed over half an hour to find the Mistake... :D

@Melba23 I read that and no, it's not the case, I will tell you what the program I need it for does.

No problem, I just thought it was not interesting for you. :D

The program is called LumiDMX. 

The lighting for events is controlled via a protocol that is called DMX. In the past you had physical DMX consoles to output that signal and control your fixtures.

Since fixtures get more complicated the requirements to the consoles raise and now we are at the point where it's cheaper to have a program like LumiDMX and a USB-to-DMX-Dongle than a well built lighting console.

LumiDMX has a function build in that is able to cycle through different lighting scenes automatically. This function does exactly what my script is supposed to do but there is a bug that doesnt get fixed:

When you give Lumi a new time to wait between changing scenes it skips to the next one no matter where it is in the current one.

You can also control the changing of the scenes manually with a keyboard button. The problem here is you can't give a rythm and then just leave it, you have to tap constantly.

That's where my script comes in and is supposed to keep on tapping when I stop doing it manually.


My problem now is, that Lumi doesn't seem to get my simulated keyboard input like every other program does. What can I do?



best regards,

If you use the Send function then you must ensure that Lumi is the currently active window.  You might be better off with ControlSend.

Thank you for your suggestion but I can't get Control Send to work either.
I don't know wich Control in my window I have to use to get it to work. I tried the main window and a few things like the big control panel but I can't get LumiDMX to get my keystroke.

best regards,
