#
Utility generic struct for manipulating 2-dimensional vectors
SF::Vector2 is a simple struct that defines a mathematical
vector with two coordinates (x and y). It can be used to
represent anything that has two dimensions: a size, a point,
a velocity, etc.
The generic parameter T is the type of the coordinates. It
can be any type that supports arithmetic operations (+, -, /, *)
and comparisons (==, !=), for example Int or Float.
You generally don't have to care about the generic form, the most common specializations have special aliases:
See also: SF.vector2f, SF.vector2i.
The SF::Vector2 struct has a small and simple interface, its
x and y members can be accessed directly and it contains no
mathematical function like dot product, cross product, length, etc.
Usage example:
v1 = SF.vector2f(16.5, 24)
v1.x = 18.2_f32
y = v1.y
v2 = v1 * 5
v3 = v1 + v2
different = (v2 != v3)
Note: for 3-dimensional vectors, see SF::Vector3.
