[L4D2 Request] Grenade Launcher Projectile Vector
 

[L4D2] Flare Gun

Could someone extract the necessary code from this plugin, just to be able to correctly align the projectile of the grenade launcher?
When Grenade Launcher shots, usually projectile flying in random direction.

I would like the projectiles fired, not to go out in a random direction, if not, where the player is aiming exactly.
