Cool concept.
Tho would be cooler if there was a big impulse that pushed you forward instead of having to mash R with 9999 max uses.
Something like panxiaohai's [L4D] China Qing Gong For Survivors (Super Jump)
Your plugin only accelerates the lunge/pounce by a little, it's not really an impulse.
Edit:There's also "The Team Ghost" [ANY/?] Advanced Multi Jump Plugin as an example of an Impulse with a forward boost.
Edit2: Anyway I looked into the source, managed to find what I was looking for and changed both fVelocity[0] and fVelocity[1] to *= 3;
I'm quite satisfied honestly I don't have the knowledge of how this stuff works but I managed to change the acceleration.
Maybe I was too critical. Sorry and Thanks.
Edit3: Also while compiling under SM 1.11.0.6820
Code:
l4d2_jet_hunter.sp(80) : warning 242: function "OnPlayerRunCmd" should return an explicit value
