Farming with ACtool

I recently got into farming and I want to try out something new.
There's this tool called ACtool for macroing in some games (Maplestory, Gunz)
So. Is there anyone into ACtool that can make a script for farming.
I already tried something like this

loop 150
GetActiveWindow CrossFire
Lef***ick
Delay 550
end

But no succes. He gets to my crossfire window but he doesn't click so I don't shoot. Any suggestions?

i think somebody already tried. I dont think the program works with crossfire.

just stand in front of the person with ur knife and put something heavy on the left mouse button. WAHLAA! you have a continuous slashing "Program"
