Connection Quality
Mirror does a lot of work to smooth out poor network connections.
However, there's only so much we can do on.
For poor connections, it's best practice to display a 'Poor Connection' warning.
Mirror's ConnectionQuality consists of three parts to make this very easy for your game.
ConnectionQuality.cs
Standalone connection quality enum & heuristics, which can be used outside of Unity if needed.
Mirror provides the following connection quality levels:
Currently it offers two heuristics:
Simple (based on Ping & Jitter)
Pragmatic (based on Snapshot Interpolation).
NetworkPingDisplay
This component can be added to the NetworkManager to display a Ping & Connection Quality indicator on the bottom right of the screen. Feel free to modify this to your needs, or create your own.
NetworkManager Callbacks
CalculateConnectionQuality() can be overwritten to inject your own heuristic. By default, it uses the Simple heuristic from above. This is called every connectionQualityInterval seconds, which can also be configured in the NetworkManager.
OnConnectionQualityChanged() can be used to show warnings to the user. By default, this emits a log message - useful for debugging user logs, etc.
