The main game loop
The main game loop is in the clip event for the ‘Pitch’ movie clip. Step one is to update the
timer. The purpose of storing the ‘startTime’ is so that it can be used to calculate the elapsed time
using
secs = int((getTimer() - startTime)/1000);
The ‘getTimer’ returns the system time in milliseconds; by subtracting the start time and dividing
by 1000, the elapsed seconds can easily be calculated. This can then be stripped into minutes and
seconds using the integer value after division by 60 and the remainder after division by 60, the
modulus operator ‘%’. The values for these two numbers are then converted in strings of two
characters and built into a string to display the time.
