Local vs Global

i use a function rapidly in a game and im thinking about turn some of the globals to Locals,

Will creating Locals take more CPU or should i create a global and just use that instead?

Readability is more important than any other concern during development IMO. So, use locals.

And the speed difference is probably laughable too :)

i can code well with out the readability, i need speed in this game, and i need all the help i can get

if Locals can speed things up, i'll use em.

cheers guys anyways
