Constructor & Destructor Documentation

DtVector2DD() [1/3]

makVre::DtVector2DD::DtVector2DD

(

)

Default constructor.

Creates a vector with coordinates (0,0)

Referenced by DtVector2DD(), operator/=(), and operator=().

DtVector2DD() [2/3]

makVre::DtVector2DD::DtVector2DD	(	double	x,
		double	y )

Constructor with x and y coordinates.

Parameters

x	The x coordinate
y	The y coordinate

References x(), and y().

DtVector2DD() [3/3]

makVre::DtVector2DD::DtVector2DD

(

const DtVector2DD &

orig

)

Copy constructor.

Parameters

orig	The vector to copy

References DtVector2DD().

Member Function Documentation

operator=()

const DtVector2DD & makVre::DtVector2DD::operator=

(

const DtVector2DD &

orig

)

Assignment operator.

Parameters

orig	The vector to copy

Returns

Reference to this vector after assignment

References DtVector2DD().

operator/=()

DtVector2DD & makVre::DtVector2DD::operator/= ( double scalar )

inline

Division assignment operator.

Divides both x and y components by a scalar value

Parameters

scalar

The scalar to divide by

Returns

Reference to this vector after division

References DtVector2DD().

setX()

void makVre::DtVector2DD::setX

(

double

x

)

Sets the x coordinate.

Parameters

x	The new x coordinate

References x().

x()

double makVre::DtVector2DD::x

(

)

const

Gets the x coordinate.

Returns

The x coordinate

Referenced by DtVector2DD(), makVre::operator<<(), and setX().

setY()

void makVre::DtVector2DD::setY

(

double

y

)

Sets the y coordinate.

Parameters

y	The new y coordinate

References y().

y()

double makVre::DtVector2DD::y

(

)

const

Gets the y coordinate.

Returns

The y coordinate

Referenced by DtVector2DD(), makVre::operator<<(), and setY().

rotate()

void makVre::DtVector2DD::rotate ( double rotationAngle )

inline

Rotates the vector counter-clockwise.

Parameters

rotationAngle

The angle to rotate in radians

length()

double makVre::DtVector2DD::length ( ) const

inline

Calculates the length/magnitude of the vector.

Returns

The length of the vector

lengthSquared()

double makVre::DtVector2DD::lengthSquared ( ) const

inline

Calculates the squared length/magnitude of the vector.

This is more efficient than length() when comparing distances, as it avoids the square root calculation

Returns

The squared length of the vector

normalize()

void makVre::DtVector2DD::normalize

(

)

Normalizes the vector.

Adjusts the vector to have a length of 1 while preserving its direction

Member Data Documentation

myX

double makVre::DtVector2DD::myX

protected

The x coordinate.

myY

double makVre::DtVector2DD::myY

protected

The y coordinate.
