Geting directions to same point through waypoints in Google Maps

Question

Hi I have some locations and a center of a location. I want to set the center location as the origin as well as the destination. I have some waypoints and I want to start from the origin and travel through the way points and return to the origin again. Can anyone help me?

Your destination point will have to be the same source

 if (origem == null) {  // origem
                            var lat = document.getElementById("lat").value;
                            var lng = document.getElementById("lng").value;
                            event.LatLng = new google.maps.LatLng(lat, lng); 
                            origem = event.LatLng;
                            addMarkerOrigem(origem);

                    } else if (destino == null) {   // destino
                        var latD = document.getElementById("latInt").value;
                        var lngD = document.getElementById("lngInt").value;
                        event.LatLng = new google.maps.LatLng(latD, lngD);
                        destino = event.LatLng;
                        addMarkerOrigem(destino);

after

 var request = {
                            origin: origem, //define a origem no paramentro do metodo route()
                            destination: origem,//define o destino no parametro do metodo route() 
                            waypoints: waypoints,
                            travelMode: mode, // o modo de gerar o caminho que vem mode = google.maps.DirectionsTravelMode.DRIVING;
                            optimizeWaypoints: true, // variavel true, optimiza o caminho, mostrará sempre o menor custo
                            provideRouteAlternatives: true //exibira rotas alternativas
                            //tem muitas outras propriedades opcionais, obrigatorias são apenas origin destination e travelMode.
                        };

                        directionsService.route(request, function(response, status) {//seta os parametros de requisição e resposta
                            if (status == google.maps.DirectionsStatus.OK) { // se as direções estiverem "OK" ele vai criar a rota
                                directionsDisplay.setDirections(response);
                            }
                        });

                        clearMarkers();
                        directionsVisible = true;
                    }

vai then using the idea of ​​putting the other points of this potos walks between source and destination, and destination = source

origin: origem, //define a origem no paramentro do metodo route() destination: origem,//define o destino no parametro do metodo route()
