This test is a speed comparison between global variables and "for this sprite only" variables. Incrementing based tests and "getting and setting" tests (which get the variable, add one, and set the value of the variable) have been provided. The tests show that across the board, "For this sprite only" variables are faster in computation, as much as 25% faster on my computer. This is a very interesting thing I have found, and I would like to share it with fellow scratchers who are in need of a little boost in processing power. I'm sure that this is already known, but it's still nice to discover something cool.
