[CustomEditor(typeof(ConnectedObjectsExample))] class ConnectLineHandleExample : Editor { float dashSize = 4.0f; void OnSceneGUI() { ConnectedObjectsExample connectedObjects = target as ConnectedObjectsExample; if (connectedObjects.objs == null) return;

Vector3 center = connectedObjects.transform.position; for (int i = 0; i < connectedObjects.objs.Length; i++) { GameObject connectedObject = connectedObjects.objs[i]; if (connectedObject) { Handles.DrawDottedLine(center, connectedObject.transform.position, dashSize); } else { Handles.DrawDottedLine(center, Vector3.zero, dashSize); } } } }
