RescaleVector

Lengthens or shortens a vector relatively preserving its direction.

Syntax

void avl::RescaleVector
(
	const avl::Vector2D& inVector,
	float inScale,
	bool inInverse,
	avl::Vector2D& outVector
)

void RescaleVector
(
	Vector2D inVector,
	float inScale,
	bool inInverse,
	out Vector2D outVector
)

Parameters

Name	Type	Default	Description
inVector	const Vector2D&
inScale	float	1.0f	Scaling factor
inInverse	bool		Switches to the inverse operation
outVector	Vector2D&

Examples

RescaleVector performed on a vector (red one) with DeltaX = 0, DeltaY = 10 with parameters inScale = 5, inInverse = True. outVector returns vector (blue one)

Errors

Error type	Description
DomainError	inScale cannot be zero in an inverse scaling in RescaleVector.
