Break a loop inside a loop with a key

Guest · 14 Jan 2018, 22:22

Loop {
 sleep 5000
      Wait2()
   }

      Wait2()
{
	Loop
	{
		Sleep 20
		PixelGetColor, col, 20, 285 
	 If col = 16777215 
		break
	else sleep 10000 ;<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
		break
	}
}

This loop searches a color. If it doesn't find it, it goes to sleep.
How can I break this sleep immediately with a key?

Use the GetKeyState function.

Either Check GetKeyState or add a determine statement like

Code: Select all

breakloop := false
Loop {

    if breakloop
        break
        
 sleep 5000
      Wait2()
   }

      Wait2()
{
	Loop
	{
		Sleep 20
		PixelGetColor, col, 20, 285 
	 If col = 16777215 
		break
	else sleep 10000 ;<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
		break
	}
}
return

esc::
breakloop := true
return

Thank you. I don't want to break the first loop, I want to break the second loop. Can I break this 10 second sleep somehow?

Try set up a timer to substitute the sleep line

Code: Select all

Sleeptime := 0
Settimer, Sleep, 1000
while sleeptime <= 10 and not breakloop
	continue

Then somewhere out the loop:

Code: Select all

Sleep:
	sleeptime += 1
return

while sleeptime <= 10 and not breakloop
continue

I would suggest not using a loop which just "continues". It will loop as fast as possible, needlessly consuming CPU time.

If you are using a loop, there is no need for a timer.

Code: Select all

while A_Index <= 100 and not breakloop
    Sleep 100

or

Code: Select all

loop 100
    Sleep 100
until breakloop

You can still set breakloop from a hotkey or any other event, and you can adjust the numbers to check more or less frequently if needed.

There may be some inaccuracy caused by "drift", as each iteration may take longer than 100 ms. If you want more accuracy, you can check the time:

Code: Select all

start := A_TickCount
while (A_TickCount - start) < 10000 and not breakloop
    Sleep 100

This may still go as much as 100 ms over 10 seconds.

If you use Sleep 10000, there is no way to cause it to return early. You can only interrupt it and do something else in the meantime (such as execute another hotkey or timer).
