Code:
register_forward( FM_TraceLine, "hook_TraceLine")
public hook_TraceLine( const float *v1, const float *v2, int fNoMonsters, edict_t *pentToSkip, TraceResult *ptr )
It's in fakemeta_const.inc
To get the victim, use: new victim = get_tr( TR_pHit );
To get the hitbox, use: new hitplace = get_tr( TR_iHitgroup );
Here is one already made for DoD, but you'll have to code in stamina and proning yourself or skip it for CS.
