Struct collider::geom::DirVec2
[−]
[src]
pub struct DirVec2 { /* fields omitted */ }A 2-D vector that separates direction from length.
This may be used rather than Vec2 if the length
may be at or near 0.0 but the direction is still important,
or to distinguish between a vector with a negative length
and a vector in the opposite direction of positive length.
Such distinctions are necessary when describing the
normal distance between PlacedShapes.
Methods
impl DirVec2[src]
pub fn new(dir: Vec2, len: f64) -> DirVec2[src]
Constructs a vector with the given direction dir and length len.
dir is normalized before being set.
pub fn dir(&self) -> Vec2[src]
Returns the direction as a unit vector.
pub fn len(&self) -> f64[src]
Returns the length of the vector. May be positive or negative.
pub fn flip(&self) -> DirVec2[src]
Returns a new vector with the same len but reversed dir.
