Calling a function from a String

[JFD]

I'm looking to make a more dynamic TopPanel, so that modders (i.e. me) can add new Yield Per Turn values without complicated workarounds that potentially conflict with other mods. To do this, though, I need to interpret a string as a function, and I'm not sure how to properly use loadstring, or whether it works fully in this game. So it would be much appreciated if someone can enlighten me as to whether this is possible. Thanks.

This is what I have:

local numGold = loadstring("JFD_Test" .. "()")()

iGoldPerTurn = iGoldPerTurn + numGold

This is the error:

attempt to perform arithmetic on local 'numGold' (a function value)

Maybe try:

loadstring("return " .. "JFD_Test" .. "()")()

And throw it into an assert() for good measure.

Assuming this page is still in-date, the load* methods have been sand-boxed and can't be used.

 

[Nutty]

My understanding was that that page is wrong. If you search the forum, other people have used that method apparently successfully.

Well, it seems that that info must be out of date, because it works according to Nutty's suggestion.

EDIT: Greninja'd

Thanks for the help Nutty, anyway.
