Variables

struct tnt::doo::objects_sys objects

struct object_data

#include <Objects.hpp>

A struct that holds the basic data of an object.

Public Functions

constexpr object_data(float angle_, Vector const &pos_, Vector const &scale_, object const &parent_ = null) noexcept

Create a new object data handle from the given params.

Parameters

• angle_: The initial angle of the object.

• scale_: The initial scale of the object.

• pos_: The initial position of the object.

• parent_: The parent of the new object. Leave it as is if you don’t want the object to have a parent.

Public Members

float angle

Vector scale

< The angle of the object.

Vector pos

< The scale of the object.

object parent

< The position of the object.

struct objects_sys

#include <Objects.hpp>

A struct that handles objects data.

Public Functions

object add_object(object_data const &data_) noexcept

Create a new object in place and add it to the system. Return the id of the newly created object.

Return

tnt::doo::object

object_data get_data(object const &id) const noexcept

Get the data of the object with the given id.

Return

object_data

Parameters

• id: The id of the object.

object from_json(nlohmann::json const &j)

Load objects data from a json chunk.

Return

The id of the created object.

Parameters

• j: The json chunk that contains the objects data.

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

Store general 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 draw_imgui(object const &id, Window const &win) noexcept

Draw widgets on the given window to modify the datas of the system.

Parameters

• id: The id of the active object.

• win: The window where to draw the widgets.

float gAngle(object const &id) const noexcept

Get the angle of the object in global context.

Return

float

Note

The function returns angle[id] if the object has no parent (aka. parent[id] == -1).

Parameters

• id: The id of the object.

Vector gScale(object const &id) const noexcept

Get the scale of the object in global context.

Return

Vector

Note

The function returns scale[id] if the object has no parent (aka. parent[id] == -1).

Parameters

• id: The id of the object.

Vector gPos(object const &id) const noexcept

Get the position of the object in global context.

Return

Vector

Note

The function returns pos[id] if the object has no parent (aka. parent[id] == -1).

Parameters

• id: The id of the object.

void set_parent(object const &id, object const &parent_) noexcept

Change the parent of the given object and apply all the necessary changes.

Parameters

• id: The id of the child object.

• parent_: The id of the new parent.

void remove(object const &id) noexcept

Remove the desired object from the objects system.

Note

Please call remove() from the other systems first.

Parameters

• id: The id of the object you want to remove.

void clear() noexcept

Remove all the objects from the objects system.

Note

Please call clear() from the other systems first.
