some help with making noobie hacks

well here is my problem
mouse_event(&H2, 0, 0, 0, 1)
Sleep((Rnd() * 50) * 100)
mouse_event(&H4, 0, 0, 0, 1)
this code is made up to be spammer , this one is lclick down lclick up so it hit a click and there is a sleep inside it , well it works fine in game but in lobby it dont o-0 so any other way to do a lclick ? (i did try timers plus without sleep and still didnt work)

second problem
i was trying to create a noobie aimbot , with #c0ol0o0r , like if the head color is pink it move the mouse pointer to the pink color so it hit the head
i know it aint gona work in maps with same color on walls or on anything else
so yes it will be bugged and will be 60/100 working but its fine ill try to pick up a unique color so i increase the efficiency but is it right o-0
i want to create it with vb not c++ and not auto it , so do u think it gona work ? well how to scan for color on screen and move the pointer to it ?


third problem just a lil modification on that
thats to reg alt+z to be hotkey
RegisterHotKey(Me.Handle, 100, MOD_ALT, Keys.Z)
so if i want to edit it to f1 it gona be
RegisterHotKey(Me.Handle, 100, 0, Keys.f1) ?
well 100 is the case , what is me.handle


thanks everyone , i know im still noob and a bit lazy to search but im really working on so many stuff
thanks again
