Member Function Documentation

◆ GetClampedPoint()

template<typename Type >

const EZ_ALWAYS_INLINE ezVec2Template< Type > ezRectTemplate< Type >::GetClampedPoint ( const ezVec2Template< Type > & vPoint ) const

The given point is clamped to the area of the rect, i.e. it will be either inside the rect or on its edge and it will have the closest possible distance to the original point.

Test:: This is new

◆ GetClampedRect()

template<typename Type >

const ezRectTemplate<Type> ezRectTemplate< Type >::GetClampedRect ( const ezRectTemplate< Type > & r ) const

inline

Clamps the given rect to the area of this rect and returns it.

If the input rect is entirely outside this rect, the result will be reduced to a point or a line closest to the input rect.

◆ IsValid()

template<typename Type >

EZ_ALWAYS_INLINE bool ezRectTemplate< Type >::IsValid

Checks whether the position and size contain valid values.

Test:: This is new

◆ MakeIntersection()

template<typename Type >

ezRectTemplate< Type > ezRectTemplate< Type >::MakeIntersection	(	const ezRectTemplate< Type > &	r0,
		const ezRectTemplate< Type > &	r1
	)

static

Creates a rect that is the intersection of the two provided rects.

If the two rects don't overlap, the result will be a valid rect, but have zero area. See IsValid() and HasNonZeroArea().

Test:: This is new

◆ MakeInvalid()

template<typename Type >

ezRectTemplate< Type > ezRectTemplate< Type >::MakeInvalid

static

Creates an 'invalid' rect.

IsValid() will return false. It is possible to make an invalid rect valid using ExpandToInclude().

Test:: This is new

◆ MakeUnion()

template<typename Type >

ezRectTemplate< Type > ezRectTemplate< Type >::MakeUnion	(	const ezRectTemplate< Type > &	r0,
		const ezRectTemplate< Type > &	r1
	)

static

Creates a rect that is the union of the two provided rects.

This is the same as constructing a bounding box around the two rects.

Test:: This is new

◆ Scale()

template<typename Type >

void ezRectTemplate< Type >::Scale	(	Type	sX,
		Type	sY
	)

Scales width and height, and moves the position as well.

Test:: This is new

◆ SetCenter()

template<typename Type >

void ezRectTemplate< Type >::SetCenter	(	Type	tX,
		Type	tY
	)

Sets the center of the rectangle.

Test:: This is new

◆ Translate()

template<typename Type >

void ezRectTemplate< Type >::Translate	(	Type	tX,
		Type	tY
	)

Moves the rectangle.
