defaultParseArgs() global variable

by James Ghitelman · in Torque Developer Network · 04/28/2013 (2:03 pm) · 3 replies

I was going through the FPS tutorial when I noticed what I consider to be an odd programming choice. In core/parseArgs.cs, in the function defaultParseArgs(), why is the for loop defining "i" as a global variable? It's a waste of memory. Also, I don't know how scope works in torquescript, can I define a local variable "i" or do all my for loops now have to use "count" or some equally arcane variable? Can I safely edit it to local or is there some good reason that it's global? I'm just a bit mystified.

Spitting out my coffee
What the.....
Not only the $i but also these:
$arg = $Game::argv[$i];
$nextArg = $Game::argv[$i+1];
$hasNextArg = $Game::argc - $i > 1;
$logModeSpecified = false;
I'm sure there is some kind of reasonable... Reason for this..... I just don't see it lol, good catch tho!

However you can have a local variable with the same name without being afraid of breaking the engine, local and global variable names can overlap.

Just want to elaborate for clarity:
$i = 3;
%i = 2;
echo($i); // outputs 3
echo(%i); // outputs 2
So you don't have to worry about local variable names.

I don't have any clue as to why they are global or whether you can change them to local, but try it and see if it works.

As long as my local "i" isn't conflicting with the global "i" I don't really care. I would never name a global variable something non-descriptive like "i", so it's not a problem. I just thought it was weird. I'm not even entirely sure what parseArgs.cs does. Presumably parsing commandline arguments? When I understand what it does I'll try changing it and seeing if it stops doing it.
