Hi ppl... I''m having some trouble reading a table from a lua script in c++: Lua:

p = {5,1}
readtable(p)

C++:

int l_readtable(lua_State* luaVM){
	if(lua_istable(luaVM,-1)){
		lua_pushnumber(luaVM,0);
		lua_gettable(luaVM,1);
		int obj = (int)lua_tonumber(luaVM,-1);
	}
	return 0;
}

I don''t know why but obj (that should have a value form the table) is always 0 and no element from the table is 0, Why? What I''m doing wrong? Filami

table constructors like {5, 1} count their indices from 1, not 0. Change the call to lua_pushnumber(luaVM, 1) and it''ll return 5.

How appropriate. You fight like a cow.
