Description

2D Vector math class for float values. This class provides access to RLPy's internal vector math library allowing vectors to be handled effortlessly, and in a manner compatible with internal RLPy data structures. It also supports operators and vector related functions.

RVector2 also provides some constants for your convenience:

Constant Description
RVector2.ZERO 2D zero vector: (0, 0)
RVector2.UNIT_X 2D x unit vector: (1, 0)
RVector2.UNIT_Y 2D y unit vector: (0, 1)
RVector2.UNIT_XY 2D vector: (1, 1)

Constructor & Destructor

__init__

Initialize a new RVector2 object as a 2D zero vector: (0, 0). 

a = RLPy.RVector2()

__init__( self, x, y )

Initialize a new RVector2 object as a 2D vector: (x, y). 

a = RLPy.RVector2(1, 2)

Parameters

x [IN] a numerical value for x coordinate - float or int
y [IN] a numerical value for y coordinate - float or int

__init__( self, args )

Initialize a new RVector2 object with another RVector2 object: args. This new RVector2 object has the same value as args. 

a = RLPy.RVector2(1, 2)
b = RLPy.RVector2(a)

Member Functions

Parameters

vV [IN] The vector - RLPy.RVector2

Returns

The value of the dot production - float

Inverse

RLPy.RVector2.Inverse ( self )

Length

RLPy.RVector2.Length ( self )

Length of the vector.

Returns

The length of this vector - float

Normalize

RLPy.RVector2.Normalize ( self )

Normalizes this vector.

Returns

The normalized vector - float

SetX

RLPy.RVector2.SetX ( self, tX )

Set the value of the x-axis.

Parameters

tX [IN] the value of the x-axis - float

SetY

RLPy.RVector2.SetY ( self, tY )

Set the value of the y-axis.

Parameters

tX [IN] the value of the y-axis.

SquaredLength

RLPy.RVector2.SquaredLength ( self )

Squared length of the vector.

Returns

The squared length of this vector - float

X

RLPy.RVector2.X ( self, args )

Get the value of the x-axis.

Returns

The value of the x-axis - float

Y

RLPy.RVector2.Y ( self, args )

Get the value of the y-axis.

Returns

The value of the y-axis - float
