Constructor & Destructor Documentation

◆ v2() [1/4]

eu::v2::v2 ( )

default

◆ v2() [2/4]

constexpr eu::v2::v2	(	float	ax,
		float	ay
	)

inlineconstexpr

Definition at line 22 of file vec2.h.

◆ v2() [3/4]

eu::v2::v2 ( const std::tuple< float, float > & a )

explicit

◆ v2() [4/4]

eu::v2::v2 ( const n2 & u )

explicit

Member Function Documentation

◆ from()

static v2 eu::v2::from ( const n2 & n )

static

◆ from_to()

static v2 eu::v2::from_to	(	const v2 &	from,
		const v2 &	to
	)

◆ get_data_ptr() [1/2]

float * eu::v2::get_data_ptr ( )

Returns an array to the data.

non const so it's useful for letting an API tweak the members.

◆ get_data_ptr() [2/2]

const float * eu::v2::get_data_ptr ( ) const

Returns an array to the data.

◆ get_flipped_y()

v2 eu::v2::get_flipped_y ( ) const

Returns a new vector where the sign of the y component is flipped.

◆ get_length()

float eu::v2::get_length ( ) const

Returns the length of the vector.

◆ get_length_squared()

float eu::v2::get_length_squared ( ) const

Returns the squared length of the vector.

This is useful if you want to compare to zero, sort by length or similar, otherwise see get_length()

◆ get_normalized()

std::optional< n2 > eu::v2::get_normalized ( ) const

Changes the length to 1.

If the calculated length is zero, the vector is changed to a known value and false is returned

◆ get_rotated()

v2 eu::v2::get_rotated ( const An & a ) const

Assumes the vector is a point and returns it if it was rotated around (0,0)

◆ normalize()

bool eu::v2::normalize ( )

Changes the length to 1.

If the calculated length is zero, the vector is changed to a known value and false is returned

◆ operator*=()

void eu::v2::operator*= ( float rhs )

◆ operator+=()

void eu::v2::operator+= ( const v2 & rhs )

◆ operator-()

v2 eu::v2::operator- ( ) const

◆ operator-=()

void eu::v2::operator-= ( const v2 & rhs )

◆ operator/=()

void eu::v2::operator/= ( float rhs )
