As you step through lines of code, the values of variables and properties change in the Watch list
and in the Variables, Locals, and Properties tabs. A yellow arrow along the left side of the
Debugger's code view indicates the line at which the Debugger stopped. Use the following
buttons along the top of the code view:
Continue
Stop Debugging
Step In advances the Debugger (indicated by the yellow arrow) into a function. Step In works
only for user-defined functions.
In the following example, if you place a breakpoint at line 7 and click Step In, the Debugger
advances to line 2, and a subsequent click of Step In will advance you to line 3. Clicking Step In
for lines that do not have user-defined functions in them advances the Debugger over a line of
code. For example, if you stop at line 2 and select Step In, the Debugger advances to line 3, as
shown in the following example:
1 function myFunction() {
2 x = 0;
3 y = 0;
4 }
5
6 mover = 1;
7 myFunction();
8 mover = 0;
Step Out advances the Debugger out of a function. This button works only if you are currently
stopped in a user-defined function; it moves the yellow arrow to the line after the one where that
function was called. In the example above, if you place a breakpoint at line 3 and click Step Out,
the Debugger moves to line 8. Clicking Step Out at a line that is not within a user-defined
function is the same as clicking Continue. For example, if you stop at line 6 and click Step Out,
the player continues executing the script until it encounters a breakpoint.
Step Over advances the Debugger over a line of code. This button moves the yellow arrow to the
next line in the script and ignores any user-defined functions. In the example above, if you are
stopped at line 7 and click Step Over, you go directly to line 8, and
Continue
leaves the line at which the player is stopped and continues playing until a breakpoint
is reached.
