Player killed Sleep player C#

Hi! how to add a condition if the player asleep?

Code:

void OnEntityDeath(BaseEntity entity, HitInfo hitinfo)
    {
            if (entity is BasePlayer)
            {
                BasePlayer victim = (BasePlayer)entity;                     if(hitinfo.Initiator != null && (hitinfo.Initiator is BasePlayer))
                    {
                        BasePlayer attacker = (BasePlayer)hitinfo.Initiator;
                        PrintToChat( string.Format("{0} killed {1}",attacker.displayName,victim.displayName) );
                    }
            }
    }

 

BasePlayer.IsSleeping() should do the trick.

Code:

void OnEntityDeath(BaseEntity entity, HitInfo hitinfo)
    {
            if (entity is BasePlayer)
            {
                BasePlayer victim = (BasePlayer)entity;                     if(hitinfo.Initiator != null && (hitinfo.Initiator is BasePlayer))
                    {
                        BasePlayer attacker = (BasePlayer)hitinfo.Initiator;
                        if(victim.IsSleeping())
                            PrintToChat( string.Format("{0} killed {1} while he was sleeping. How weak!",attacker.displayName, victim.displayName) );
                        else
                            PrintToChat( string.Format("{0} killed {1}",attacker.displayName, victim.displayName) );
                    }
            }
    }

 

Thanx! How else to add to the code range from which the conclusion was killed?
