Introduction
Introduction
One of the powerful features of AutoPlay Media Studio is its scripting engine. This document
will introduce you to the new scripting environment and language.
AutoPlay scripting is very simple, with only a handful of concepts to learn. Here is what it looks
like:
a = 5;
if a < 10 then
Dialog.Message("Guess what?", "a is less than 10");
end
(Note: this script is only a demonstration. Don’t worry if you don’t understand it yet.)
The example above assigns a value to a variable, tests the contents of that variable, and if the
value turns out to be less than 10, uses an AutoPlay action called “Dialog.Message” to display a
message to the user.
New programmers and experienced coders alike will find that AutoPlay Media Studio is a
powerful, flexible yet simple scripting environment to work in.
A Quick Example of Scripting in AutoPlay Media Studio
