... that a lua file has a limit of 200 local variables?
Code: Select all
Error
toybox/LGML.lua:125: Syntax error: hunt_TMP:201: main function has more than 200 local variables
Traceback
[C]: in function 'load'
toybox/LGML.lua:125: in function 'getSettingsToSave'
toybox/LGML.lua:165: in function 'saveData'

Any fix for this? (This is the way I make save files.)

Yep, lua has a hard-coded limit of 200 local variables within a given scope, or at least within a function. If you wrap some of those variables into a table, you can fit in more, because a table can hold many values, while only "consuming" one local.
Usually I think that reaching this limit is a code smell.

Ahhh, heheh.
I use a lib called saveTable that saves the game data (nothing bulky, just states and triggers) in a lua file. And wince it was/is a "small" game and bitser seemed not to work on empty files or something, I used that and it's worked up to this point
.
I guess maybe I'll try to really get bitser to work.

Something sinister here...how about if I make the lib write the tables in the save file as global instead of local ...just as a quick hack (for now)
?

The saving and loading must be such easy as
Code: Select all
function on_save ()
love.save ("data", Data) -- big letter means for global
end
Code: Select all
function on_load ()
Data = love.load ("data")
end
Where Data is a table with tables and values, no metatables, no userdata, no functions or methods.
