Help understanding a small script

[Makaveli]

#include <Misc.au3>

While 1

If _IsPressed('BB') Then

MouseClick("Left", 706, 311, 1, 1)

MouseClick("Left", 1873, 638, 1, 3)

MouseClick("Left", 810, 888, 1, 1)

While _IsPressed('BB')

Sleep(100)

WEnd

EndIf

WEnd

1920x1080

Windowed Fullscreen mode

So, ive got a few questions, i understand the X-Y cordinates, but what does this mean "While _IsPressed('BB')" / "If _IsPressed('BB')", While what is pressed ??!!?!

Oh, and i asume

1920x1080

Windowed Fullscreen mode

is not a part of the script

Hi, Makaveli, welcome to the forum. Please read through the _IsPressed section in the Help file. It gives you all the hexkeys that are part of this function. BB is toward the bottom.
