Member Function Documentation

Count()

int CMyListener::Count ( eSprite t )

private

Count the number of bodies out of *m_pBodyA and *m_pBodyB that have objects have a given sprite type. Returns 0, 1, or 2, of course.

Parameters

t	Sprite Type.

Returns

Number of *m_pBodyA and *m_pBodyB that have type t.

Here is the call graph for this function:

GetSpeed()

float CMyListener::GetSpeed ( const b2Vec2 & p )

private

Collision speed is proportional to the magnitude of the relative velocity.

Parameters

p	World point.

Returns

Collision speed in Physics World units.

Here is the caller graph for this function:

PreSolve()

void CMyListener::PreSolve	(	b2Contact *	c,
		const b2Manifold *	m )

Presolve function. Renders a colored star at each contact point and plays the appropriate sound, depending on what type of objects are contacting.

Parameters

c	Pointer to the contact.
m	Pointer to the old contact manifold as it was before this contact.
