I know this thread is pretty old, but i would like to correct a major error with Phanx'es code, which is probably just a typo:
Lua Code:
if not type(dst) then dst = { } end
If the not is not there it will auto reset your settings to the default one every time you log in. |
type() always returns a string no matter what you give it. This means using it directly as a conditional will always return
true and using
not on it will always return
false. The correction on this should be the following.
Code:
if type(dst) ~= "table" then dst = { } end
