Public Functions

void add_object(object const &id, bone_comp const &data_)

Add a new object to the bones system.

Parameters

• id: The id of the object that will have a bone component.

• data_: The data that the object will contain.

void from_json(object const &id, nlohmann::json const &j)

Add new objects to the bones system by using data from a json chunk.

Parameters

• id: The id of the object to add to the bones system.

• j: The json chunk containing the objects data.

void to_json(object const &id, nlohmann::json &j)

Store bones data of a specific object to a json chunk.

Parameters

• id: The id of the object to serialize to json.

• j: The json chunk where the data will be saved.

void remove(object const &id) noexcept

Remove an object from the bones system.

Parameters

• id: The id of the object to remove.

void clear() noexcept

Remove all the objects from the bones system.

Vector bottom(object const &id) const noexcept

Get the other end of the bone of the given object.

Return

tnt::Vector

Parameters

• id: The id of the object that has the desired bone.

void follow(object const &id, Vector const &target) noexcept

Move the desired joint towards target.

Parameters

• id: The id of the joint you want to reach the target.

• target: The destination you want the joint to reach.
