Question

I come from other programming languages and I am new to Unityscript. I am trying to understand what a Unityscript code is doing.

I found this line

var guiTouchPos : Vector2 = touch.position - guiTouchOffset;

What kind of declaration is this? What is this line doing?
Wouldn’t it be easy to write

var guiTouchPos = touch.position - guiTouchOffset;

as I don’t see Vector2 being used anywhere in the code?

is the line assigning the subtraction to both variables?

thanks.

That is not JavaScript, it’s ActionScript 3 or UnityScript. the : indicates a type declaration.
