nw::kernel::ObjectSystem

struct ObjectSystem : public nw::kernel::Service 

The object system creates, serializes, and deserializes entities.

Public Functions

ObjectSystem(MemoryResource *scope)

ObjectSystem(const ObjectSystem&) = delete

ObjectSystem(ObjectSystem&&) = default

ObjectSystem &operator=(ObjectSystem&) = delete

ObjectSystem &operator=(ObjectSystem&&) = default

~ObjectSystem()

void destroy(ObjectHandle obj): Destroys a single object.

template<typename T> T *get(ObjectHandle obj): Gets an object.

ObjectBase *get_object_base(ObjectHandle obj) const: Gets an object.

ObjectBase *get_by_tag(StringView tag, int nth = 0) const: Gets object by tag.

ObjectBase *alloc(ObjectType object_type)

template<typename T> T *load_file(const std::filesystem::path &archive): Loads an object from file system

Note

Player objects (BIC) loaded from the file system will be loaded as instances, all others as blueprints.

template<typename T> T *load(Resref resref): Loads an object from resource system.

template<typename T> T *load_instance(const GffStruct &archive): Loads an object from gff isntance.

template<typename T> T *load_instance(const nlohmann::json &archive): Loads an object from json isntance.

Player *load_player(StringView cdkey, StringView resref): Loads an object from resource system.

template<typename T> T *make(): Creates a new object.

Area *make_area(Resref area): Creates an area object.

Module *make_module(): Creates a module object

Warning

: nw::kernel::resman().load_module(...) must be called before this.

void run_instantiate_callback(ObjectBase *obj): Run instantiate callback.

void set_instantiate_callback(void (*callback)(ObjectBase*)): Set instatiate callback.

bool valid(ObjectHandle obj) const: Determines of object handle is valid.

MemoryResource *allocator() const noexcept: Gets the memory allocator for the servce.

inline virtual void initialize(ServiceInitTime): Initializes a service

Note

Every service will be called with as many values as exist in ServiceInitTime. it’s up to the service itself to filter/ignore what’s not relevant to them.
