RayCast()

bool b2CircleShape::RayCast ( b2RayCastOutput * output, const b2RayCastInput & input, const b2Transform & transform, int32 childIndex ) const

overridevirtual

Implement b2Shape.

Note

because the circle is solid, rays that start inside do not hit because the normal is not defined.

Implements b2Shape.

TestPoint()

bool b2CircleShape::TestPoint ( const b2Transform & transform, const b2Vec2 & p ) const

overridevirtual

Implement b2Shape.

Implements b2Shape.
