Detailed Description

Box-shaped model to support collisions.

Given the name Box2D, this is your primary model class. Most of the time, unless it is a player controlled avatar, you do not even need to subclass BoxObject. Look through some of our samples and see how many times we use this class.

Unless otherwise specified, the center of mass is as the center.

Constructor & Destructor Documentation

◆ BoxObstacle()

cugl::physics2::BoxObstacle::BoxObstacle ( void )

inline

Creates a new box object at the origin.

NEVER USE A CONSTRUCTOR WITH NEW. If you want to allocate an object on the heap, use one of the static constructors instead.

◆ ~BoxObstacle()

virtual cugl::physics2::BoxObstacle::~BoxObstacle ( )

inlinevirtual

Deletes this physics object and all of its resources.

We have to make the destructor public so that we can polymorphically delete physics objects.

A non-default destructor is necessary since we must release all claims on scene graph nodes.

Member Function Documentation

◆ alloc() [1/3]

static std::shared_ptr< BoxObstacle > cugl::physics2::BoxObstacle::alloc ( )

inlinestatic

Returns a newly allocated box object at the origin with no size.

Returns: a newly allocated box object at the given point with no size.

◆ alloc() [2/3]

static std::shared_ptr< BoxObstacle > cugl::physics2::BoxObstacle::alloc ( const Vec2 pos )

inlinestatic

Returns a newly allocated box object at the given point with no size.

The scene graph is completely decoupled from the physics system. The node does not have to be the same size as the physics body. We only guarantee that the scene graph node is positioned correctly according to the drawing scale.

Parameters

pos	Initial position in world coordinates

Returns: a newly allocated box object at the given point with no size.

◆ alloc() [3/3]

static std::shared_ptr< BoxObstacle > cugl::physics2::BoxObstacle::alloc	(	const Vec2	pos,
		const Size	size
	)

inlinestatic

Returns a newly allocated box object of the given dimensions.

The scene graph is completely decoupled from the physics system. The node does not have to be the same size as the physics body. We only guarantee that the scene graph node is positioned correctly according to the drawing scale.

Parameters

pos	Initial position in world coordinates
size	The box size (width and height)

Returns: a newly allocated box object of the given dimensions.

◆ createFixtures()

virtual void cugl::physics2::BoxObstacle::createFixtures ( )

overridevirtual

Create new fixtures for this body, defining the shape

This is the primary method to override for custom physics objects

Reimplemented from cugl::physics2::SimpleObstacle.

◆ getDimension()

const Size cugl::physics2::BoxObstacle::getDimension ( ) const

inline

Returns the dimensions of this box

Returns: the dimensions of this box

◆ getHeight()

float cugl::physics2::BoxObstacle::getHeight ( ) const

inline

Returns the box height

Returns: the box height

◆ getWidth()

float cugl::physics2::BoxObstacle::getWidth ( ) const

inline

Returns the box width

Returns: the box width

◆ init() [1/3]

virtual bool cugl::physics2::BoxObstacle::init ( )

inlineoverridevirtual

Initializes a new box object at the origin with no size.

Returns: true if the obstacle is initialized properly, false otherwise.

Reimplemented from cugl::physics2::Obstacle.

◆ init() [2/3]

virtual bool cugl::physics2::BoxObstacle::init ( const Vec2 pos )

inlineoverridevirtual

Initializes a new box object at the given point with no size.

The scene graph is completely decoupled from the physics system. The node does not have to be the same size as the physics body. We only guarantee that the scene graph node is positioned correctly according to the drawing scale.

Parameters

pos	Initial position in world coordinates

Returns: true if the obstacle is initialized properly, false otherwise.

Reimplemented from cugl::physics2::Obstacle.

◆ init() [3/3]

virtual bool cugl::physics2::BoxObstacle::init	(	const Vec2	pos,
		const Size	size
	)

virtual

Initializes a new box object of the given dimensions.

The scene graph is completely decoupled from the physics system. The node does not have to be the same size as the physics body. We only guarantee that the scene graph node is positioned correctly according to the drawing scale.

Parameters

pos	Initial position in world coordinates
size	The box size (width and height)

Returns: true if the obstacle is initialized properly, false otherwise.

◆ releaseFixtures()

virtual void cugl::physics2::BoxObstacle::releaseFixtures ( )

overridevirtual

Release the fixtures for this body, reseting the shape

This is the primary method to override for custom physics objects

Reimplemented from cugl::physics2::SimpleObstacle.

◆ resetDebug()

virtual void cugl::physics2::BoxObstacle::resetDebug ( )

overrideprotectedvirtual

Creates the outline of the physics fixtures in the debug node

The debug node is use to outline the fixtures attached to this object. This is very useful when the fixtures have a very different shape than the texture (e.g. a circular shape attached to a square texture).

Reimplemented from cugl::physics2::Obstacle.

◆ resize()

void cugl::physics2::BoxObstacle::resize ( const Size size )

protected

Resets the polygon vertices in the shape to match the dimension.

This is an internal method and it does not mark the physics object as dirty.

Parameters

size	The new dimension (width and height)

◆ setDimension() [1/2]

void cugl::physics2::BoxObstacle::setDimension ( const Size value )

inline

Sets the dimensions of this box

Parameters

value the dimensions of this box

◆ setDimension() [2/2]

void cugl::physics2::BoxObstacle::setDimension	(	float	width,
		float	height
	)

inline

Sets the dimensions of this box

Parameters

width	The width of this box
height	The height of this box

◆ setHeight()

void cugl::physics2::BoxObstacle::setHeight ( float value )

inline

Sets the box height

Parameters

value the box height

◆ setWidth()

void cugl::physics2::BoxObstacle::setWidth ( float value )

inline

Sets the box width

Parameters

value the box width

Member Data Documentation

◆ _dimension

Size cugl::physics2::BoxObstacle::_dimension

protected

The width and height of the box

◆ _geometry

b2Fixture* cugl::physics2::BoxObstacle::_geometry

protected

A cache value for the fixture (for resizing)

◆ _shape

b2PolygonShape cugl::physics2::BoxObstacle::_shape

protected

Shape information for this box
