Constructor & Destructor Documentation

Menge::Math::AABBShape::AABBShape	(	const Vector2 &	minPt,
		const Vector2 &	maxPt
	)

Constructor.

Parameters

minPt	The minimum values of the bounding box along the x- and y-axes, respectively.
maxPt	The maximum values of the bounding box along the x- and y-axes, respectively.

Menge::Math::AABBShape::AABBShape

(

const AABBShape &

shape

)

Copy constructor.

Parameters

shape

The shape to copy from.

Menge::Math::AABBShape::AABBShape	(	const AABBShape &	shape,
		const Vector2 &	offset
	)

Initializes this shape as an translated version of the input shape.

Parameters

shape	The shape to copy from.
offset	defines an offset from the copied AABBShape for the new AABBShape

Member Function Documentation

bool Menge::Math::AABBShape::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::AABBCondition.

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

virtual

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

Parameters

pt	The point to test.
pos	The position of the circle.

Returns

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

Implements Menge::Math::Geometry2D.

AABBShape Menge::Math::AABBShape::operator+

(

const Vector2 &

pt

)

Construct an offset version of this shape.

Parameters

pt	The offset value.

Returns

A new AABBShape offset from this one by the vector pt.

void Menge::Math::AABBShape::set	(	const Vector2 &	minPt,
		const Vector2 &	maxPt
	)

Sets the extent of the AABB.

Parameters

minPt	The minimum point (along the x- and y-axes).
maxPt	The maximum point (along the x- and y-axes).

void Menge::Math::AABBShape::setSize

(

const Vector2 &

size

)

Sets the size of the AABB.

It implicitly changes the maximum extent of the box, keeping the minimum point where it is.

Parameters

size	The width and height of the box.
