So even if you add for example an alpha key to your defaults table, the table loaded from the saved variables where there is no alpha key will still be used.
Something like this should work:
Code:
for k,v in pairs(defaults) do
if type(MYMODDB[k]) == "nil" then
MYMODB[k] = v
end
end
That or using a metatable as Slakah said. |
I use this method, and it provides *no* protection if performed within the VARIABLES_LOADED event. My solution was gross, involving a timed event one second after VARIABLES_LOADED. I guess you can also use a one-shot PLAYER_ENTERED_WORLD event, but that didn't occur to me at the time.
That metatable thing looks *amazing.* I wish I hadn't been intimidated by the underscores when I first stumbled upon the concept, it looks like quite the ideal solution.
