See trace() of Flash when running in browser

Question

What\'s an easy way to see the trace() output of Flash/Flex movies when running in any browser?

Answer 1

Download and install the content debugger version of Flash Player.

Enable trace logging (official guide) by adding an mm.cfg file:

ErrorReportingEnable=1

    TraceOutputFileEnable=1

Where to save mm.cfg depends on the OS:

• Mac OS X: /Library/Application Support/Macromedia
• Windows: %HOMEDRIVE%\%HOMEPATH%
• Linux: /home/user name

The log file, flashlog.txt, can be found at:

• Windows 95/98/ME/2000/XP: C:\Documents and Settings\username\Application Data\Macromedia\Flash Player\Logs
• Windows Vista: C:\Users\username\AppData\Roaming\Macromedia\Flash Player\Logs
• Mac OS X: /Users/username/Library/Preferences/Macromedia/Flash Player/Logs/
• Linux: /home/username/.macromedia/Flash_Player/Logs/

Optionally, you can install the Firefox add-on FBTracer which displays the trace output in a Firebug panel.

Vizzy makes life easier if you want a basic logfile viewer. You just install the debug player and then install Vizzy. It is a window that tails the flashlog file. The sweet thing is that is does all the mm.cfg file b.s. for you.

Probably not as fancy as the others or cutting edge, but I used to create my own log function in the flash movie (funnily enough, called log) that called trace and also called a js function on the page (using whatever method your comfortable with). The function on the page was just a simple console.log() with Firebug. Simple and worked a treat.
