bool Menge::Math::CircleShape::containsPoint ( const Vector2 & pt ) const

virtual

Determine if the point is inside the shape based on the instance properties.

Parameters

pt	The point to test.

Returns: True if the point is inside the shape, false otherwise.

Implements Menge::Math::Geometry2D.

Reimplemented in Menge::BFSM::CircleCondition.

bool Menge::Math::CircleShape::containsPoint	(	const Vector2 &	pt,
		const Vector2 &	pos
	)		const

virtual

Determine if the point is inside a circle, centered on the given position.

Parameters

pt	The point to test.
pos	The position of the circle's center.

Returns: True if the point is inside the shape, false otherwise.

Implements Menge::Math::Geometry2D.

CircleShape Menge::Math::CircleShape::operator+ ( const Vector2 & pt )

Construct an offset version of this shape.

Parameters

pt	The offset value.

Returns: A new CircleShape offset from this one by the vector pt.

void Menge::Math::CircleShape::set	(	const Vector2 &	center,
		float	radius
	)

inline
