Member Function Documentation

◆ Count()

int CMyListener::Count ( eSprite  t)
private

Count number of bodies that have sprite type t.

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
tSprite Type.
Returns
Number of *m_pBodyA and *m_pBodyB that have type t.

◆ GetSpeed()

float CMyListener::GetSpeed ( const b2Vec2 &  p)
private

Get the collision speed.

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

Parameters
pWorld point.
Returns
Collision speed in Physics World units.

◆ PreSolve()

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

Presolve function.

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

Parameters
cPointer to the contact.
mPointer to the old contact manifold as it was before this contact.
