[~solved] Global_variables with Lua

[ZombieKnight]

Hi,
Any idea how to store Lua variable into global_variables?


Once I'll get wml stored into global variable...
How (in event/function) replace wml of scenario with wml from global variable?

The Lua API to global variables is not finalized, so it might change without warning, but it does exist.

Code: Select all

local GV = wesnoth.experimental.wml.global_vars
local ns = "your_namespace"
-- Set a global variable
GV[ns].varname = "stuff"
GV[ns]["varname"] = "stuff"
-- Read a global variable
print(GV[ns].varname)
-- Clear a global variable (not sure if this one actually works)
GV[ns].varname = nil

That's all equivalent to using the WML tags with immediate=yes. There's no Lua equivalent to immediate=no at the moment.

...
If I understand right this should create a variable varname and set it to "stuff"

Code: Select all

[lua]
    code=<<
local GV = wesnoth.experimental.wml.global_vars
local ns = "Bandits_from_Brown_Hills"
GV[ns].varname = "stuff"
GV[ns]["varname"] = "stuff"
>>
[/lua]

...
But it does nothing
