SF::Vector2(T)

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:

• SF::Vector2(Float32) is SF::Vector2f
• SF::Vector2(Int32) is SF::Vector2i

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)
