Script

Scripts are one of the many ways to program your game using code. What's
unique about script resources is that they are independent of any object
and can work on one or many objects. They can also be passed parameters
which makes them much more modular than code actions and initialization
code. It's very easy with a script to create reusable code that in most
cases you can copy and paste into any game and use. This can also be
useful if you want to work on a game with other people as they can write
scripts without having access to your game and then copy them in later.
