IDE of your choosing (though, of course, the menus and key presses will be differ-

Basic Breakpoint
A breakpoint on a line of code tells the debugger that whenever it reaches that
particular line, it should pause the program. To set a breakpoint in Visual Studio,
move the cursor to the line you'd like the breakpoint on and press F9 (alternat-
ively, you can click the grey column on the left side of the editor window). When a
breakpoint is hit, you can mouse over variables to see their current value. A break-
point in the Update function of Enemy.cs is shown in Figure B.1 .
