I'm working on a game engine, and I'm working on adding scripting to it using ChaiScript. In my engine, I have a simple Entity Component System that uses templates. It has a struct for each object, and then structures for different components. Each component contains a pointer to it's parent. There is a script component, which is where all the ChaiScript stuff sits.
In C++, to add and get components I simply write:
object->AddComponent<Sprite>("path-to-sprite");
object->GetComponent<Transform>().position.x = 10;
(position is simply a structure containing a float for the x and y positions
My GetComponent's definition looks like this:
template<typename T> T& GetComponent() const {
auto ptr(componentArray[getComponentTypeID<T>()]);
return *static_cast<T*>(ptr);
}
And AddComponent:
template <typename T, typename... TArgs>
T& AddComponent(TArgs&&... mArgs) {
T* c(new T(std::forward<TArgs>(mArgs)...));
c->parentObject = this;
std::unique_ptr<Component> uPtr{ c };
components.emplace_back(std::move(uPtr));
componentArray[getComponentTypeID<T>()] = c;
componentBitSet[getComponentTypeID<T>()] = true;
c->Ready();
return *c;
}
I want to be able to do that same from ChaiScript, but using the pointer to the parent object that the script component has. How would I go about this? All I've done so far is add basic functions to the script, such as OnUpdate() and OnInit(), as well as a function to log stuff to the engine's debug console. Sorry if I didn't use correct terminology, and thanks in advance.
