Struct collider::geom::Vec2
[−]
[src]
pub struct Vec2 {
pub x: f64,
pub y: f64,
}A 2-D Cartesian vector using finite f64 values.
Fields
x: f64
The x-coordinate.
y: f64
The y-coordinate.
Methods
impl Vec2[src]
pub fn new(x: f64, y: f64) -> Vec2[src]
Constructs a vector with the given x and y coordinates.
pub fn zero() -> Vec2[src]
Constructs a (0, 0) vector.
pub fn len_sq(&self) -> f64[src]
Computes the square of the Euclidean length of the vector.
Due to underflow, this might be 0.0 even if x and y are non-zero but very small.
pub fn len(&self) -> f64[src]
Computes the the Euclidean length of the vector.
Due to underflow, this might be 0.0 even if x and y are non-zero but very small.
pub fn normalize(&self) -> Option<Vec2>[src]
Returns a vector in the same direction as self but with length (approximately) 1.0,
or None if self.len() == 0.0.
pub fn dist_sq(&self, other: &Vec2) -> f64[src]
Computes the square of the Euclidean distance between two vectors.
pub fn dist(&self, other: &Vec2) -> f64[src]
Computes the Euclidean distance between two vectors.
pub fn lerp(&self, other: Vec2, ratio: f64) -> Vec2[src]
Linearly interpolates between self and other.
Using ratio = 0.0 will return self, and using ratio = 1.0 will return other.
Can also extrapolate using ratio > 1.0 or ratio < 0.0.
pub fn rotate(&self, angle: f64) -> Vec2[src]
Rotates the vector by angle radians counter-clockwise (assuming +x is right and +y is up).
