Attach Lua script To C++ class!

["Ive" <neosettlers@...>]

Alright!

I ll try to b more precise!

What I m trying to do is to assign to each actor in a game environment a
script ai!

I m wondering if I must do:

lua_State *m_lua;

	if ((m_lua = lua_open()) == NULL)
	{
		Trace("ERROR: LUA initialization failed!\n\n");
	}
	else
	{
		Trace("TELL: LUA initialization successful!\n\n");

		luaopen_base(m_lua);
		luaopen_table(m_lua);
		luaopen_io(m_lua);
		luaopen_string(m_lua);
		luaopen_math(m_lua);
		luaopen_debug(m_lua);

		RegisterFunction(); /// register all functions

	Int l_status = luaL_loadfile(m_lua, in_name.GetName());
	lua_settop(m_lua, 0);

	if (l_status != 0) 
	{
		lua_error(m_lua);
	}
	}

to each of the script!


Then update them individually each frame with:

lua_pcall(m_lua, 0, 0, 0);

or

my first guest is to have only one lua_State instance and register all
functions once and then keep track with a pointer to each
luaL_loadfile... but I cant find the way to retrieve them... can anyone
clear this up please?

Is lua_open() should be call once (then register all possible functions
once) or to all attached scripts? What is the ultimate way to do this
with out unnecessary overheads?

thx

Hi all!

How do you Init an ai script?

And how do you update it...


Ive tried init like with:

luaL_loadfile(LUA()->m_lua, "primitive_cubeAI.lua");

and call it everyframe with:

lua_call(LUA()->m_lua, 0, LUA_MULTRET);

is this the right way to do this?

thx
