The following are the comments for code sample 2-7:
•
Line 22
: A new
StreamWriter
object is created to write debug strings
to a file on the computer. The file is created inside
Application.
persistentDataPath
; this points to a system location that is always writable.
•
Line 30
: The
Application.RegisterLogCallBack
method is invoked with a
function reference to
HandleLog
as an argument. This relies on delegates. In
short, a reference to the
HandleLog
function is passed, and this will be called
when an error or exception occurs that allows us to write details to a logfile.
