Alright, so i've already got a bind on my mouse1 button as follows >

/bind mouse 1 +vstr attackon attackoff
set attackon "+attack; +sprint"
/set attackoff "-attack; -attack; -sprint; -sprint"

how could i work something into that to make it so also on attackon mouse sens lowers to 1, for example, and then returns to what its normally at on attackoff? also for some reason everytime i connect to any server i've gotta open up the console and /set attackon and attackoff again and re-enter the entire script and i dunno how to stop that :/

Thanks for any input :D

well... was messing around and actually found a bind that works for it :D just simply added a "sensitivity 1" to it lol
