Detailed Description

A structure representing a 2D Vector.

Member Function Documentation

dist()

static float meteor::SVector2::dist ( SVector2 v1, SVector2 v2 )

inlinestatic

Computes the euclidian distance.

Parameters

v1	vector 1
v2	vector 2

Returns

euclidian distance between the two vectors

make()

static SVector2 meteor::SVector2::make ( float x, float y )

inlinestatic

returns a vector2 using x and y. (similar to Vector(x,y) constructor)

Parameters

x	value in x-axis
y	value in y-axis

Returns

vector2 containing (x,y)

one()

static SVector2 meteor::SVector2::one ( )

inlinestatic

Returns

(1,1)

parse()

static bool meteor::SVector2::parse ( std::string str, SVector2 & out )

inlinestatic

Parses a string to a vector, serialized vector to be in the form '(x,y)'.

Parameters

str	serialised string containg vector2 data
out	Vector2 struct reference to update values.

Returns

true is de-serialization was successful.

scale()

static SVector2 meteor::SVector2::scale ( SVector2 v1, SVector2 v2 )

inlinestatic

Multiplies each component of v1 with their respective parts in v2.

Parameters

v1	vector 1
v2	vector 2

Returns

scaled vector

zero()

static SVector2 meteor::SVector2::zero ( )

inlinestatic

Returns

(0,0)
