Trace (message)

The command trace () is used to display something on the output panel. Usage of trace action is very useful in further programming later, as fault testing in a program line. An example of using trace action script as following:

• Click frame 1, then open the action panel and typing the script: trace (1000); then run the movie by pressing CTRL+Enter. It will appear the text "1000" on the output panel.

• Press Ctrl + W to return to the Stage. Next change the action in frame 1 become: trace ("hello how are you?"); Then run movie again. So it will appear in output panel as follows:

• Press Ctrl + W to return to the Stage. Next change the action in frame 1 become: trace (number); Then run movie again. So it will appear in output panel as follows:

• Press Ctrl + W to return to the Stage. Next add the action in frame 1 becomes:

number = 1000;

trace (number);

Then run movie again. So the view that emerges is as follows:

The conclusion that can be taken are as follows:

• Value inside () in the action trace () can be filled with numbers.
• Word "hello how are you?" can be displayed because it is a string object (located inside "").
• Word number can not be displayed, because not enclosed in "", so the word number is considered as a variable that must be defined first.
• Additional action number = 1000; is defining the number variable, so this variable is valued at 1000 and can be displayed by the action trace ().
