Implementations

impl Vector2f

pub const ZERO: Vector2f

Zero vector, addition identity value.

pub const ONE: Vector2f

One vector, multiplication identity value.

pub const UP: Vector2f

Up vector in the top-left coordinate system common to 2D drawing systems.

pub const RIGHT: Vector2f

Right vector in the top-left coordinate system common to 2D drawing systems.

pub const DOWN: Vector2f

Down vector in the top-left coordinate system common to 2D drawing systems.

pub const LEFT: Vector2f

Left vector in the top-left coordinate system common to 2D drawing systems.

pub fn new(x: f32, y: f32) -> Self

Construct a vector from the components.

pub fn to_i32(self) -> Vector2i

Converts the vector to unsigned integer values. Truncates integers, if you want your components to be rounded you must do this manually first.

pub fn as_size(self) -> Sizef

Converts this vector to a size value with the x representing width and the y representing height.

pub fn rounded(self) -> Vector2f

Rounds the components of the vector to the nearest integer. Rounds half-way values away from 0.

pub fn dot(self, rhs: Vector2f) -> f32

Dot product of two vectors.

pub fn len_squared(self) -> f32

The squared length of the vector

pub fn len(self) -> f32

The length of the vector. This requires performing a square root, so the squared length should be preferred where possible.

pub fn abs(self) -> Self

Absolute value of the vector components.

pub fn is_approx_eq(self, other: impl Into<Vector2f>, epsilon: f32) -> bool

Tests if two vectors are approximately equal to each other within a given epsilon. The epsilon is applied component-wise. If you would like to check that two vectors are within a specified distance of each other, you should subtract one from the other and check the length of the resulting distance vector between them.
