Extra Lua table in a library registration

["Geo Massar" <LuaGeo@...>]

Hi, experts

 

I had trouble to run my LuaScene after I just added another table in Lua library registration. The code below is part of LuaScene program. Is there some explanation why it fails?

 

Please pardon my Pascal.

 

Thanks in advance.

// Lua library registration

function luaopen_scene(L : PLua_State) : Integer;
var
  i : Integer;
begin
  // Store Scene functions in 'scene' table
  luaL_openlib(L, 'scene', @_sceneLib, 0);

 

  // Store Scene constants in 'scene' table
  lua_pushstring(L, 'scene');
  lua_gettable(L, LUA_GLOBALSINDEX);
  i := 0;
  repeat
    lua_pushstring(L, _constants[i].name);
    lua_pushstring(L, _constants[i].value);
    lua_rawset(L, -3);
    Inc(i);
  until _constants[i].name = nil;

 

  // Store key constants in 'keybaord' table
  i := 0;
  repeat
    lua_pushstring(L, _keys[i].name);
    lua_pushnumber(L, _keys[i].value);
    lua_rawset(L, -3);
    Inc(i);
  until _keys[i].name = nil;
  lua_setglobal(L, 'keyboard');

 

  // Store mouse button constants in 'mouse' table
  i := 0;
  repeat
    lua_pushstring(L, _buttons[i].name);
    lua_pushnumber(L, _buttons[i].value);
    lua_rawset(L, -3);
    Inc(i);
  until _buttons[i].name = nil;
  lua_setglobal(L, 'mouse');

 

  lua_settop(L, 0);
  result := 0;
end;
