Saving mod user data on file

[Franck83]

HI,

Maybe someone can help.

it seems that FA lua doesn't support such lua standard :

Code: Select all

local file ,err = io.open(filename, "wb")

WARNING: Error running OnRelease script in <deleted object>: ...lliance\mods\heroes_reloaded\modules\datamanager.lua(136): access to nonexistent global variable "io"


So, how can we open access to files ?

Really annoying for my mod because i need to save players templates on local file. Somebody got experience on loading/saving data on file with FA ?

you can write to game.prefs, e.g.
https://github.com/Bra1nwash3d/FAF-stuf ... fs.lua#L75
dunno if it's possible to write to other files at all

GPG intentionally removed most direct file operations from their subset of LUA in order to prevent misuse.

Ty for your replies

Really really annoying, i have a complete template table to save...

i will take a look at game.prefs. Maybe if i serialize my tables to game.prefs...

Hope there are not small limits with game.prefs....

For the topic purpose and for exposing my happiness, just wanna say it's working and its so simple to do (less than 10 lines of code) !

Code: Select all

local Prefs = import('/lua/user/prefs.lua')

function SaveTemplates(table)
   Prefs.SetToCurrentProfile('Templates', table)
end

function GetTemplates()
   return Prefs.GetFromCurrentProfile('Templates')
end

It saves a complete database and because it's internal -> cheats safe ^^

Hi,

although most of the (lua) functions in game are disabled that allow you to extract data from the game and indeed add new data to a game be it running in the sim or UI side (while in game or not), there is actually away to get data in and out of the game.. however it does involve a 3rd party program to be running that connects to the game...

i did say you need a 3rd party program... which ZEP kindly written/gave to me years ago, i just added more functions to the external program/script to make it do what i wanted...

i can post it if you want.. it's a python script.. so you will have to know python to get what you want from it..

If I understand it correctly...
it starts a server and launches the game, then it listens to GPGNetSend calls from the game and saves whatever is needed.

a proxy that intercepts requests and does stuff?
