Detailed Description

Abstract base class for generic collider object.

This class contains basic interfaces for colliders. Most of the functionalities are implemented within this class, except the member function Collider2::VelocityAt. This class also let the subclasses to provide a Surface2 instance to define collider surface using Collider2::SetSurface function.

Member Typedef Documentation

OnBeginUpdateCallback

using CubbyFlow::Collider2::OnBeginUpdateCallback = std::function<void(Collider2*, double, double)>

Callback function type for update calls.

This type of callback function will take the collider pointer, current time, and time interval in seconds.

Constructor & Destructor Documentation

Collider2()

CubbyFlow::Collider2::Collider2

(

)

Default constructor.

~Collider2()

virtual CubbyFlow::Collider2::~Collider2 ( )

virtual

Default destructor.

Member Function Documentation

GetClosestPoint()

void CubbyFlow::Collider2::GetClosestPoint ( const Surface2Ptr &  surface, const Vector2D &  queryPoint, ColliderQueryResult *  result  ) const

protected

Outputs closest point's information.

GetFrictionCoefficient()

double CubbyFlow::Collider2::GetFrictionCoefficient

(

)

const

Returns friction coefficient.

GetSurface()

const Surface2Ptr& CubbyFlow::Collider2::GetSurface

(

)

const

Returns the surface instance.

IsPenetrating()

bool CubbyFlow::Collider2::IsPenetrating ( const ColliderQueryResult &  colliderPoint, const Vector2D &  position, double  radius  )

protected

Returns true if given point is in the opposite side of the surface.

ResolveCollision()

void CubbyFlow::Collider2::ResolveCollision	(	double	radius,
		double	restitutionCoefficient,
		Vector2D *	position,
		Vector2D *	velocity
	)

Resolves collision for given point.

Parameters

radius	Radius of the colliding point.
restitutionCoefficient	Defines the restitution effect.
position	Input and output position of the point.
velocity	Input and output velocity of the point.

SetFrictionCoefficient()

void CubbyFlow::Collider2::SetFrictionCoefficient

(

double

newFrictionCoeffient

)

Sets the friction coefficient.

This function assigns the friction coefficient to the collider. Any negative inputs will be clamped to zero.

SetOnBeginUpdateCallback()

void CubbyFlow::Collider2::SetOnBeginUpdateCallback

(

const OnBeginUpdateCallback &

callback

)

Sets the callback function to be called when Collider2::update function is invoked.

The callback function takes current simulation time in seconds unit. Use this callback to track any motion or state changes related to this collider.

Parameters

[in]

callback

The callback function.

SetSurface()

void CubbyFlow::Collider2::SetSurface ( const Surface2Ptr &  newSurface )

protected

Assigns the surface instance from the subclass.

Update()

void CubbyFlow::Collider2::Update	(	double	currentTimeInSeconds,
		double	timeIntervalInSeconds
	)

Updates the collider state.

VelocityAt()

virtual Vector2D CubbyFlow::Collider2::VelocityAt ( const Vector2D &  point ) const

pure virtual

Returns the velocity of the collider at given point.

Implemented in CubbyFlow::RigidBodyCollider2, and CubbyFlow::ColliderSet2.
