Is there an easy and fast way to check if user has no network connection?

Hi @gubebra. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Yes, there is a way to check if a user is connected to the network in NormalVR. You can use the connected property of the _realtime object to check if the user is connected to the room. If the user is not connected to the room, it's likely that they don't have a network connection. Here is a code snippet from the NormalVR documentation:

private void Update() {  
    if (!_realtime.connected)  
        return;  
    // rest of the code
}

private void Update() {  
    if (!_realtime.connected)  
        return;  
    // rest of the code
}

In this code, Update() is a method that is called every frame in Unity. At the beginning of Update(), there is a check to see if _realtime.connected is false. If it is, the method returns early, effectively skipping the rest of the code for that frame. This is a quick and easy way to check if the user is connected to the network. Please note that this check is specific to the connection with the NormalVR room and may not cover all cases of network disconnection. For a more general network check, you might need to use Unity's built-in networking APIs or other networking libraries. You can find more details in the NormalVR documentation (https://normcore.io/documentation/guides/creating-a-multiplayer-drawing-app#brush-1). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

And in that case _realtime is defined as what @Normcore Assistant

Let me check the knowledge base for you. One moment! :books: ---------------------- The _realtime in the code snippet is an instance of the Realtime class in NormalVR. The Realtime class manages a Room object and synchronizes its datastore to RealtimeViews and RealtimeComponents in the scene. Here is an example of how you might define _realtime:

private Realtime _realtime;

private Realtime _realtime;

Then, you would typically initialize _realtime in the Start() or Awake() method of your MonoBehaviour:

void Start() {
    _realtime = GetComponent<Realtime>();
}

void Start() {
    _realtime = GetComponent<Realtime>();
}

In this code, GetComponent<Realtime>() is a Unity method that gets the Realtime component attached to the same GameObject as the script. You can find more details in the NormalVR documentation (https://normcore.io/documentation/reference/classes/Normal.Realtime.Realtime). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

can I check the same thing using a RealtimeView @Normcore Assistant

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can check the connection status using a RealtimeView as well. The RealtimeView class has a realtime property that gets the Realtime component associated with the RealtimeView. You can use this property to check if the Realtime component is connected to the room. Here's how you might do it:

RealtimeView realtimeView = GetComponent<RealtimeView>();
if (!realtimeView.realtime.connected)
{
    // Handle the case where the user is not connected
}

RealtimeView realtimeView = GetComponent<RealtimeView>();
if (!realtimeView.realtime.connected)
{
    // Handle the case where the user is not connected
}

In this code, GetComponent<RealtimeView>() is a Unity method that gets the RealtimeView component attached to the same GameObject as the script. The realtime property of RealtimeView gets the Realtime component that the RealtimeView is registered with. Please note that this check is specific to the connection with the NormalVR room and may not cover all cases of network disconnection. For a more general network check, you might need to use Unity's built-in networking APIs or other networking libraries. You can find more details in the NormalVR documentation (https://normcore.io/documentation/realtime/realtimeview). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

great thanks Can I also identify if the user is lagging in terms of his network? @Normcore Assistant

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- While the provided knowledge sources do not directly provide a method to check if a user is experiencing network lag, Normcore does implement congestion control to manage network performance. This feature is part of the WebRTC protocol that Normcore uses for networking. It can automatically adjust the rate at which updates are sent to the server to utilize the maximum bandwidth available while still keeping updates smooth for users with poor connections. However, to monitor network lag or latency directly, you might need to implement additional networking code or use a networking library that provides such features. Unity's built-in networking APIs or other networking libraries might provide such functionality. For more information on Normcore's congestion control, you can refer to the Normcore documentation (https://normcore.io/documentation/architecture/transport#webrtc-implements-congestion-control). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

check room.ping if you want to know if you are lagging

Will do thanks
