Struct sfml::system::Vector2

#[repr(C)]
pub struct Vector2<T> {
    pub x: T,
    pub y: T,
}

Utility type for manipulating 2-dimensional vectors.

Vector2 is a simple type 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 type parameter T is the type of the coordinates.

You generally don't have to care about the generic form (Vector2<T>), the most common specializations have special type aliases:

• Vector2<f32> is Vector2f
• Vector2<i32> is Vector2i
• Vector2<u32> is Vector2u

The Vector2 type has a small and simple interface, its x and y members can be accessed directly (there are no accessors like set_x(), get_x()) and it contains no mathematical function like dot product, cross product, length, etc.

Usage example

let mut v1 = Vector2f::new(16.5, 24.0);
v1.x = 18.2;
let y = v1.y;

let v2 = v1 * 5.0;
let v3 = v1 + v2;
assert_ne!(v2, v3);

Note: for 3-dimensional vectors, see Vector3.

Fields

x: T

X coordinate of the vector.

y: T

Y coordinate of the vector.
