Lua: for beginner

The begin

• What is Programming?
• The Editor
• Variables in Lua
• LUA - Mathe
• Comments - Keywords
• Operations of Comparison / Logical Operations
• Chunks / Blocks
• Strings
• Loops
• Conditional Structures
• Tables
• Functions

the advanced

• The generic for

Lua - Functions

• Basic Functions
• table

The other

• Different Editors
• Pacman for LuaX with SDL

To use Lua in C

• Hallo World with Lua

Links

• Different games which are using LUA
• Links in german
• Links in english

For those, who will not only use LUA for their game, I would like to show some possibilties to integrate lua in C.


Integration of libraries

#pragma comment(lib, "lib/lua")
#pragma comment(lib, "lib/lualib")

Header - Files

extern "C"
{
#include "include/lua.h"
#include "include/lualib.h"
#include "include/lauxlib.h"
}

Creation of an instance.

lua_State* L;

int main(int argc, char* argv[])
{

Open Lua.

L = lua_open();

Open required libraries. For our Hello we only need the base-library and the IO-libraries.

luaopen_base(L);
// luaopen_string(L);
// luaopen_table(L);
// luaopen_math(L);
// luaopen_debug(L);
luaopen_io(L);

Execute Lua-File

lua_dofile(L,"my.lua");

Closing Lua.

lua_close(L);

Ready

return 0;
}


Code of my.lua:

print("Hello from LUA")


Libraries and header can be downloaded here .

They are 7-zip archived. Shows the best compression ratio at the moment.

And then thus it should look:





#pragma comment(lib, "lib/lua")
#pragma comment(lib, "lib/lualib")

extern "C"
{
#include "include/lua.h"
#include "include/lualib.h"
#include "include/lauxlib.h"
}

lua_State* L;

int main(int argc, char* argv[])
{
L=lua_open();

luaopen_base(L);
// luaopen_string(L);
// luaopen_table(L);
// luaopen_math(L);
// luaopen_debug(L);
luaopen_io(L);

lua_dofile(L,"my.lua");

lua_close(L);
return 0;
}
