Heya, I'm wondering if there's any way to output the console to a .txt file on a non-development build.

I’ve been putting in little easter eggs via Debug.Log(); and I’d like to output the console to a .txt file so that these easter eggs can actually be discovered. However, the only answer I’ve found would be to make it a development build. However, I don’t want there to be a “development build” mark in the corner of my actual build.

You have to store the log in a file manually.
I suggest you create the file at the beginning, then add stuff to it. Don’t store all the text in one variable and then write it at the end… it could override and crash the app.

To write files find some info around: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/file-system/how-to-write-to-a-text-file
