HowTo using LUA script as data file

[AndyGFX]

Sample data file [game.lua]:

return
{
   pos = {0,1,2},
   name = "player1",
   other =
	{
		items =
			{"item1","item1","item1"}
	}

}

 

 

call in code:

 

GameData = dofile("game.lua")

-- test data

print(GameData.pos[1],GameData.pos[2],GameData.pos[3])
print(GameData.name)
print(GameData.other.items[1])
print(GameData.other.items[2])
print(GameData.other.items[3])

 

Note: When your data are static, then is possible compile file to binary format: luac -o game.data game.lua, but then you don't forget change filename in your code, when output filename isn't same.

i hope to understand this soon ^^ thanks

 

I was really just avoiding this issue altogether but now I say, "let's do this!"

[flachdrache]

Yeah, one of my projects "might" incorporate Lua exclusively and handling its datastructures is something i have to do "next".

Thx for the heads up.

Can you run this from script?

luac -o game.data game.lua

 

Because my program doesn't accept that.

[AndyGFX]

of course

 

 

method #1

os.execute("luac -o game.data game.lua")

 

method #2

os.execute("path to bat file, where bat file contains luac ....")

 

EDIT:

 

When you haven't installed full LUA libs for windows, use this link http://code.google.com/p/luaforwindows/downloads/detail?name=LuaForWindows_v5.1.4-37.exe'>http://code.google.com/p/luaforwindows/downloads/detail?name=LuaForWindows_v5.1.4-37.exe from main page: http://code.google.com/p/luaforwindows/

Thats briljant Andy! I see that this works fine.

 

I wonder how the binary files can be loaded though. I assume Lua can somehow load the binary file an parse it back into a normal Lua for running with 'dofile'.
