In this tutorial i'll show you what's going on inside the Script Operator in a very simple way. We'll create a simple script and you don't really need any MAXScript knowledge to understand it.
Update:
The Dollar sign ($) means Selection. It specifies that you're looking for an object in the scene.
The dot between an object and a propertie (like $Sphere.Radius) means "access this propertie".
The Speed Vector [0,0,1] makes the particle travels 4800 units per sec. or 160 units per frame in a 30 frame/sec animation.
