Knife throwing

Description:
My version of the throwing knife. To throw a knife into the passer must be:
1) a player must be in the hands of a knife;
2) Select a passerby in front of you, press ~ sight ~ (right mouse button). The red indicator will appear out (if you need another bystander, a press release of the sight pointer will disappear). Passers-by in front of the player are selected within 5-10 game.
3) press ~ Yes ~ (' Y ') and ~ fire ~ (left mouse button) without releasing the press ~ sight ~ (right mouse button). After the death of a passerby at the player adds one star. If you do not press a key ~ ~ Yes (' Y '), then standard stab.
The script works ONLY when a player fails a mission.
Note: The pedov of the gangs, the script is not valid.
