Global variables and Local Map variables.

[Homicide13]

I see, so global vars are re-declared every time the script is run, but local map vars are more like (if they aren't actually, though I don't have a very good knowledge of game scripting as a whole yet) private class variables for each map.

I feel like this could cause a memory leaks though. Are local map variables kept in memory every session (whether the player is in the map that uses them or not), or are the read/written to some save file somewhere or something and only loaded during loading screens when they're needed?
