[Solved, with known issue] Logging with SharpReality

In the samples provided by @Egorbo headds an event handler for logging in one sample.

When I try to use this, no output ever appears if I write a logging statement.

So these lines of code produce this output:

Log.LogMessage += l => { Debug.WriteLine(l.Level + ":  " + l.Message); };
Debug.WriteLine(LogLevel.Warning, "MS debug logger.");
Urho.IO.Log.Write(LogLevel.Warning, "Urho3d logger");

MS debug logger.: Warning

Now, every now and then, Visual Studio’s output window will show a message that does appear to have come from the Urho.dll, typically some error message that must have used the Urho log. I assume that because the format is the same as the event handler.

My question is how to use it?

I think the right answer is that logging is disabled by default
You can try this to make it work.

#define URHO3D_LOGGING 1
#include "Urho3D/IO/Log.h"

If this is insufficient, and no better answer is forthcoming, I will jump onto Windows and find out whats going on

I have Windows, but I tend not to ever boot into it.

I’m working with the SharpReality binding for Urho.dll.

It’s all c#.

Maybe it’s related to this.

Got it working, but it’s a bet messed up.

In the start method, added this code:

Log.Level = (int)LogLevel.Error;
Log.LogMessage += l => { Debug.WriteLine(l.Level + ":)  " + l.Message); };

Then to log something, here’s an example

Urho.IO.Log.Write(LogLevel.Error, "This is the start finished message using urho logging via handler");

This will output

[Fri Jan 25 15:00:25 2019] WARNING: This is the start finished message using urho logging via handler

To show how messed up it is, wrote this code:

Log.Level = (int)LogLevel.Debug;
Urho.IO.Log.Write(LogLevel.Raw, "Set to debug. This is the the raw message");
Urho.IO.Log.Write(LogLevel.Debug, "This is the debug message");
Urho.IO.Log.Write(LogLevel.Info, "This is the info message");
Urho.IO.Log.Write(LogLevel.Warning, "This is the warning message");
Urho.IO.Log.Write(LogLevel.Error, "This is the error message");
Urho.IO.Log.Write(LogLevel.None, "This is the none message");

Log.Level = (int)LogLevel.None;
Urho.IO.Log.Write(LogLevel.Raw, "Set to none. This is the the raw message");
Urho.IO.Log.Write(LogLevel.Debug, "This is the debug message");
Urho.IO.Log.Write(LogLevel.Info, "This is the info message");
Urho.IO.Log.Write(LogLevel.Warning, "This is the warning message");
Urho.IO.Log.Write(LogLevel.Error, "This is the error message");
Urho.IO.Log.Write(LogLevel.None, "This is the none message");

Which outputs this:
