Where do I get the modified version of Lua 5.0?

[Lionhardt]

The wiki mentions that FA uses a modified version of Lua. I built Lua 5.0 from the official website, but apparently that version does not work for FA files. For example when I run the interpreter with a <mapname>_save.lua it sayst it does not know the typecaste or constructor like function calls BOOLEAN, STRING etc.

Snippet from such a file:

Code: Select all

MasterChain = {
        ['_MASTERCHAIN_'] = {
            Markers = {
                ['AmphPN10'] = {
                    ['hint'] = BOOLEAN( true ),
                    ['type'] = STRING( 'Amphibious Path Node' ),
                    ['adjacentTo'] = STRING( 'AmphPN03 AmphPN04' ),
                    ['color'] = STRING( 'ff00ffff' ),
                    ['graph'] = STRING( 'DefaultAmphibious' ),
                    ['prop'] = STRING( '/env/common/props/markers/M_Path_prop.bp' ),
                    ['orientation'] = VECTOR3( 0, -0, 0 ),
                    ['position'] = VECTOR3( 460.5, 32.9141, 204.5 ),
                },

Dunno... are these custom functions that are defined elsewhere and the map files get loaded where the functions are defined already or are these predefined functions of that modified lua interpreter? And where do I get that modified one if this is the case?

I dont think you need modified lua 5.

The types you are looking for (boolean, string) are defined in a file somewhere in the scd files.

The problem is you are trying to build a file by itself, instead of the entire project.

How are you building this?

I just ran the interpreter with it `lua map_save.lua`.

I want to write better version of the props transformation script i hacked together in python a few years back and for that I need to parse the tables in the save.lua into table objects... which works just fine with the exception of the functions BOOLEAN etc. But okay I can just define dummy function for them as I don't need their implementation... I think.

Ultra hack job is you can paste the types into your map. It will work. Proper solution is to build everythijng

Guess that won't be necessary for what I want to do. I will come back if I was wrong about that, thanks.

here are functions for maps lua files used by FAF map editor:

Oy, nice. Thanks!

To be more specific, it is this file:
mohodata/lua/dataInit.lua

Code: Select all

# Copyright � 2005 Gas Powered Games, Inc.  All rights reserved.

function BOOLEAN(b)
   return b
end

function INTEGER(i)
   return i
end

function FLOAT(f)
   return f
end

function VECTOR2(x,y)
   return { x, y, type = 'VECTOR2' }
end

function VECTOR3(x,y,z)
   return { x, y, z, type = 'VECTOR3' }
end

function RECTANGLE(x0,y0,x1,y1)
   return { x0, y0, x1, y1, type = 'RECTANGLE' }
end

function STRING(s)
   return s
end

function GROUP(group)
   group.type = 'GROUP'
   return group
end


Up to this point I still don't know its actual purpose.
