Re: Getting Lua tables from C

[Ultron14@...]

Thanks for the help. This is all working great for me now! What do weak 
tables mean? I saw that on the Lua 4.1 (possible) feature list.

These are regular tables.  Only the keys are the numbers 1, 2, ...

lua_newtable(state);
lua_pushnumber(state, 1);
lua_pushnumber(state, lastworld->active);
lua_settable(state,-3);

or:

lua_newtable(state);
lua_pushnumber(state, lastworld->active);
lua_rawseti(state, -2, 1);  // the 1 is the numeric index

Same as above:

lua_pushstring(state, "active");
lua_gettable(state, <tableindex>);

or

lua_pushnumber(state, 1);
lua_gettable(state, <tableindex>);

or

lua_rawgeti(state, <tableindex>, 1);  // get field nr 1

or iterate over all elements using lua_next().
