Debug messages with Flex?

Question

What's the quickest way to print "debug" messages from Flex? You know, things like "got a mouse click at ($x, $y)" or "received and event from $sender".

Answer 1

trace(somestring)

Answer 2

trace(mouseEvent.x + ", " + mouseEvent.y);

prints it to the console if you're using Eclipse/Flex Builder.

Answer 3

Using trace() is a simple way to see messages in the Flex Builder console. But you have to run in debug mode to see them. You can also get trace statements to print to a local file. For more complex logging there is a Log4J-like framework in the Flex SDK. More information on all of this is in the Flex Documentation:
