Detailed Description

A record of contact between a shape (which may be static, kinematic, or dynamic) and a dynamic circle. Collision detection functions take as input a contact descriptor with the pointers to the shapes, and it fills in the details of the contact if there is one. This filled-out contact descriptor is then passed to the collision response function.

Constructor & Destructor Documentation

CContactDesc() [1/2]

Shapes::CContactDesc::CContactDesc	(	CShape *	p0,
		CDynamicCircle *	p1 )

This constructor constructs a contact descriptor given a pointer to a shape and a pointer to a dynamic circle. No attempt is made to determine whether these shapes are indeed in contact, and the pointers may be null.

Parameters

p0	Pointer to a shape.
p1	Pointer to a dynamic circle.

CContactDesc() [2/2]

Shapes::CContactDesc::CContactDesc

(

)

The default constructor constructs a contact descriptor whose pointers are null. What could possibly go wrong?
