Problem when using more classes in Hololens Emulator
Hi guys,
I have 2 classes (communication_final and backup) in my application. When I try to set a bool variable in the backup class from the communication_final class, it didn't work. Does the hololens emulator supports the usage of more classes and should it be possible to set a variable in another class? Does this work on hololens?
Thanks,
Chris

Could you please post your code on the bool variable and changing it?
Hi,
Backup is my second class.
Backup.comm_displayed = true;
The funny thing is that the code works in the unity editor and also when I build a app for the desktop, only in the hololens emulator this didn't work.
@ChristophMarko I think what Shayne was referring to was you need to post the whole method containing where you change the variable not just a single line where you call something true. There could be a number of different things that could go wrong causing something like your variable not to be true.
In order for someone to be able to help you out you need to show everywhere in your script that you reference your class and the variable.

@dbarrett here are my 2 classes:
Communication_v3.cs (only a extract)
using System;
using System.IO;
using System.Linq;
using System.Collections;
using System.Runtime;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System.Diagnostics;
using System.Collections.ObjectModel;
using test_neu;
if !UNITY_EDITOR
using Windows.Networking.Sockets;
using Windows.Networking;
using Windows.Networking.Connectivity;
using Windows.Devices.Bluetooth;
using Windows.Devices.Bluetooth.GenericAttributeProfile;
using Windows.Devices.Enumeration;
using Windows.Storage.Streams;
using test;
using Windows.UI.Core;
using System.Threading.Tasks;
using backup_scene;
endif
namespace comm_final
{
public class Communication_v3 : MonoBehaviour { public Dropdown comm; public Dropdown comm_type; public Button Start_Stop_Conn; public Button Setup_Conn; public Dropdown BLE_ScanResults; public Button Scan_BLE_Button; public static bool udp_client_active; //status of the active communications sessions public static bool udp_server_active; public static bool tcp_client_active; public static bool tcp_server_active; public static bool ble_client_active; public static bool ble_server_active; public string UDP_ClientIP; public string UDP_ClientPort; public string UDP_ServerPort; public static string IP_address; public static string UDP_Client_Port; public static string UDP_Server_Port; public Text connect_status; public RawImage comm_status; //data for the dynamic connection symbols private Texture2D myTexture_comm; // Will be called everytime, when the scene will be reloaded void Start() { comm.gameObject.SetActive(false); comm_type.gameObject.SetActive(false); Start_Stop_Conn.gameObject.SetActive(false); Setup_Conn.gameObject.SetActive(true); comm_status.gameObject.SetActive(false); connect_status.GetComponentInChildren<Text>().text = "Connection status: No communication selected"; BLE_ScanResults.gameObject.SetActive(false); Scan_BLE_Button.gameObject.SetActive(false); if (backup_scene.Backup.scene_first_time) { connect_status.gameObject.SetActive(true); backup_scene.Backup.scene_first_time = false; }}
}
}
}
and here is the backup file where the variables are located:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Collections.ObjectModel;
if !UNITY_EDITOR
using Windows.Networking.Sockets;
using Windows.Networking;
using Windows.Networking.Connectivity;
using Windows.Devices.Bluetooth;
using Windows.Devices.Bluetooth.GenericAttributeProfile;
using Windows.Devices.Enumeration;
using Windows.Storage.Streams;
using test;
using test_neu;
using comm_final;
using Windows.UI.Core;
using System.Threading.Tasks;
endif
namespace backup_scene
{
public class Backup
{
public static bool scene_first_time = true;
public static bool udp_selected;
public static bool tcp_selected;
public static bool ble_selected;
public static bool comm_displayed;
public static bool udp_client_selected; public static bool udp_server_selected; public static bool tcp_client_selected; public static bool tcp_server_selected; public static bool ble_client_selected; public static bool ble_server_selected; public static bool udp_client_active; //status of the active communications sessions public static bool udp_server_active; public static bool tcp_client_active; public static bool tcp_server_active; public static bool ble_client_active; public static bool ble_server_active; public static bool ble_devices_found; public static string IP_address; public static string Client_Port; public static string Server_Port;}
}
Call me blind but, I don't see anywhere in this code where you say:
Backup.comm_displayed = true;I'd also assume you have all of your required permissions set under the Player Settings?

@dbarret: I'm sry I copied only a part of the source code and the mentioned part was in the other part. I set all the needed capabilites and when I run it as a Desktop app the program works, only it doesn't work with the emulator and the hololens.
@dbarrett: The start function in my communication_v3 class compares if a value of the backup class is set and afterwards sets a gameobject active and show a text in a textfield but this wouldn't work on the emulator and on the hololens.
I solved the problem I forgot to instantiate the needed class to create an object.
