Modularity
Modularity is a word you probably thought you'd only hear in programmers'
circles. Well, in many ways, scripting is in fact programming; many of the same
concepts apply. Modularity is an attempt to place programming code in
appropriate sections that make sense. If you were making a “House” program,
you would have a “Kitchen” module with code in it that applied to kitchen
appliances, and a “Bathroom” module with code that applied to bathroom
appliances. You would not want your “blender” code residing in your Bathroom
module. It makes it hard to read, hard to understand, and most importantly, hard
to change later. That is, unless you make margaritas in your bathroom’s jet spa!
Script programming is much simpler than real computer language programming,
but scripts can become large and unwieldy too, so modularity begins to play a
bigger importance, as your scripts become more complex.
Let’s assume that we are asked to program a script for a "Zoo Animals" pre-
show that has five video segments all coming off the same DVD player, being
shown to an audience on ten different monitors where all the monitors display
the same video. Let’s further assume that the pre-show is started manually by
an operator, after the audience has filled the pre-show area. We will use a V4+
for this job. For simplicity, we’ll also assume a frame rate of 30 frames per
second, even though the players really run at 29.97.
Note
When working with a real show such as this one, always use the exact
frame rate of the players, projectors, or whatever media source you are using.
Even miniscule differences in frame rate can have a profound impact on the
quality of your show.
