Using trace
When you use the trace
action in a script, you can send information to the Output window. For example, while testing a movie or scene, you can send specific programming notes to the window or have specific results appear when a button is pressed or a frame is played. The trace
action is similar to the JavaScript alert
statement.
When you use the trace
action in a script, you can use expressions as arguments. The value of an expression is displayed in the Output window in test-movie mode, as in the following:
onClipEvent(enterFrame){ trace("onClipEvent enterFrame " + enterFrame++) }
![]()
The
trace
action returns values that are displayed in the Output window.
