Use of underscore Syntax

[sw1 10]

Sorry this going to sound really basic (:o) but I'm trying to learn to script and I was wandering how the _ syntax is used?

For example

_num=player countEnemy list _triggerN1

What is the significance of the underscore there, as opposed to just "num=player"?

Many thanks in advance

With the underscore the variable is local and it's valid only for the script...If u don't use the underscore the variable is saved and u can use it in another script.

This can help u better :)

_variable is local to the script and doesn't need to be defined globally. the _variable can take many forms

in the case you have there (which is probably a snippet from a larger script), _num is the player and _triggerN1 is a generic form, or it is defined someplace else.

btw: please change the title to something worth reading
