Detailed Description

Capsule-shaped model to support collisions.

A capsule is a box with semicircular ends along the major axis. They are a popular physics object, particularly for character avatars. The rounded ends means they are less likely to snag, and they naturally fall off platforms when they go too far.

If width < height, the capsule will be oriented vertically with the rounded portions at the top and bottom. Otherwise it will be oriented horizontally. The constructors allow some control over the capsule shape. You can have half-capsules or full capsules. In the case where width == height, the capsule will be a circle or semicircle, depending on the capsula shape.

Constructor & Destructor Documentation

◆ CapsuleObstacle()

cugl::physics2::CapsuleObstacle::CapsuleObstacle ( void )

inline

Creates a new capsule 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.

◆ ~CapsuleObstacle()

virtual cugl::physics2::CapsuleObstacle::~CapsuleObstacle ( )

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() [1/4]

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

inlinestatic

Returns a new capsule object at the origin with no size.

Returns: a new capsule object at the origin with no size.

◆ alloc() [2/4]

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

inlinestatic

Returns a new capsule 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 new capsule object at the given point with no size.

◆ alloc() [3/4]

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

inlinestatic

Returns a new capsule object of the given dimensions.

The orientation of the capsule will be a full capsule along the major axis. If width == height, it will be a simple circle.

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 capsule size (width and height)

Returns: a new capsule object of the given dimensions.

◆ alloc() [4/4]

static std::shared_ptr<CapsuleObstacle> cugl::physics2::CapsuleObstacle::alloc	(	const Vec2	pos,
		const Size	size,
		poly2::Capsule	shape
	)

inlinestatic

Returns a new capsule object of the given dimensions and orientation.

The orientation of the capsule is determined by the major axis. A HALF capsule is rounded on the left for horizontal orientation and on the bottom for vertical orientation. A HALF_REVERSE capsule is the reverse.

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 capsule size (width and height)
shape	The capsule shape/orientation

Returns: a new capsule object of the given dimensions and orientation.

◆ getSeamOffset()

float cugl::physics2::CapsuleObstacle::getSeamOffset ( ) const

inline

Returns the seam offset of the core rectangle

If the center rectangle is exactly the same size as the circle radius, you may get catching at the seems. To prevent this, you should make the center rectangle epsilon narrower so that everything rolls off the round shape. This parameter is that epsilon value
