I'm working on setting up application-wide variables, and I'm caching some global variables (and functions) that I use a lot. I'm not sure if locally caching a table ALSO locally caches all its indexes.

This seems like a dumb question, my first thought was "of course!", but then I found out all the global variables are stored in _G and I can't imagine that "local _G = _G" would cache every global variable in a single line, seems like that's too dangerous to allow.

Let's say I have a situation like this, I declare some global variables in my main.lua file:

1
2
3
4

gameVars = {}
gameVars.sfx = true
gameVars.currentLevel = 1
gameVars.playerName = "Default Player"
