Как мне отследить мой комплиментарный заказ? (Чтобы я мог заказать его повторно)
Моя проблема: я запускаю Visual Studio 2012, пишу приложение на C++. Я привязал систему сценариев Lua к своему проекту с помощью LuaBind.
LuaBind прячет вещи Lua и выясняет, как связать их с языком Lua (или какой-то магией)
Я могу взять объект, вызвать для него функцию и передать объект C++ для передачи функции сценария lua.
// ScriptComponent.h
class ScriptComponent : public Component
{
public:
virtual void Initialize();
virtual void Update();
protected:
luabind::object luaDataTable;
Entity* mOwner;
-
// ScriptComponent.cpp
void ScriptComponent::Initialize() {
luabind::object compiledScript;
luaL_loadfile(L, "myScript.lua");
luabind::object compiledScript(luabind::from_stack(L, -1));
luaDataTable = compiledScript();
lua_pop(L, 1);
}
void ScriptComponent::Update() {
luaDataTable["run"](mOwner); // Compiler breaks here.
// Note: if I remove mOwner from the mix (and in the script file) everything works and runs fine.
}
Прохладный! Но чтобы это заработало, luabind нужно знать, что такое mOwner (Entity*), и определить ti. Итак, я определяю его в другом файле:
// GameScriptingSystem.cpp
using namespace luabind;
module(inLuaState)
[
class_<GameObject>("GameObject"),
class_<Entity, bases<GameObject> >("Entity")
.def("DebugGetName", &Entity::DebugGetName)
];
Процесс выглядит примерно так: 
Результат:
ошибка C2504: «Сущность»: базовый класс не определен

Насколько я могу судить, это связано с порядком сборки. Насколько я понимаю, Luabind делает все это во время компиляции, и когда я сначала смотрю на компиляцию, ScriptComponent компилируется первым, а GameScriptSystem компилируется после. Когда ScriptComponent строится, все ошибки luabind проходят. ТОГДА после сборки GameScriptSystem (которая определяет все, на что жалуется LuaBind)
So:
Как отследить заказ на сборку? Посмотрите, какие файлы запускают сборку других, чтобы я мог изменить их по своему вкусу? (это большой проект, это не так просто, как смотреть на него 2 секунды)
Если вы знаете luabind, я прав в том, что это проблема?
Другие данные:
-- myScript.lua
local Cat = {}
local ticks = 0
function Cat.run(entity)
ticks = ticks + 1
LOG(tostring(ticks))
LOG(entity:DebugGetName())
end
return Cat
