You’ll want to set up your mm.cfg file to look like this:

TraceOutputFileEnable=1

ErrorReportingEnable=1

MaxWarnings=500

With logging now enabled, details will be stored in a log file called flashlog.txt whose

location is operating-system specific (see table 23.3).

With the configuration good to go, you can now use it via the

trace()

function.

23.1.3 Using the trace() function

trace()

is a simple global function that is available from anywhere in your code. It lets

you record text to the flashlog.txt log file. Now that you have mm.cfg set up, you can

use this function, as listing 23.1 demonstrates.

<mx:Label text="Type in something:"/>

<mx:TextInput id="something"/>

<mx:Button click="trace('Something is currently: ' + something.text)"

label="Record Something"/>

When you type something and click the Record Something button, the text you type

shows up in the flashlog.txt file (listing 23.2 shows an example).

*** WARNING: Please use gotoAndPlay(1) in the last frame of your Motif

creative if you intend to loop. ***

*** Please use 'stop();' at the end of your Motif creative if you do not

intend for it to loop. ***

MaxWarnings Number

Maximum number of warnings to record.

Default is

100; use 0 for unlimited.
