Checking if block is in cupboard radius?

Hi,

I would like to know if the entity on which the player strikes is in a construction zone or not. That would allow me not to do control if the entity is out of range of a cupboard.

Code:

        private void OnEntityTakeDamage(BaseCombatEntity entity, HitInfo hitInfo)
        {
            if (entity == null || hitInfo == null) return;
            ulong targetID = 0;
            targetID = entity.OwnerID;
            if (!timeForRaid && (entity is BuildingBlock || entity is SimpleBuildingBlock || entity is Door || entity.ShortPrefabName.Contains(".deployed")))
            {
                if (hitInfo.Initiator is BasePlayer)
                {
                    BasePlayer player = (BasePlayer)hitInfo.Initiator;
                    if (!player.IsBuildingBlocked()) return;
                    if (IsOwner(player.userID, entity.OwnerID)) return;
                    NullifyDamage(hitInfo);
                    SendReply(player, msg("notraidhour", player.UserIDString));
                }
                else if (hitInfo.Initiator is FireBall)
                {
                    FireBall fireBall = (FireBall)hitInfo.Initiator;
                    if (IsOwner(fireBall.OwnerID, entity.OwnerID)) return;
                    NullifyDamage(hitInfo);
                }
            }
            else if (raidOn && targetID.IsSteamId() && IsClanOffline(targetID))
            {
                if (hitInfo.Initiator is BasePlayer)
                {
                    BasePlayer player = (BasePlayer)hitInfo.Initiator;
                    NullifyDamage(hitInfo);
                    SendReply(player, msg("playersnotonline", player.UserIDString));
                }
            }
        }

Thank you for your help
