just qb? why ask for a pure qb library? if you're looking for a pure qb lib, you might as well go for an asm lib or whatever. believe me, there's lots of non-qb coded libs out there. they very much so outnumber the number of qb libs, plus they're many many MANY times faster.
qb libs? hmm... try:
nexus lib
har 13++
pqblib
oh, btw, this isn't a lib, but you could just copy-paste the subs in.
