    pub o: Vect,
    pub v: Vect,
}

Fields

o: Vect

v: Vect

Implementations

impl Ray

pub fn new(ox: f32, oy: f32, vx: f32, vy: f32) -> Self

pub fn from_points(a: Vect, b: Vect) -> Self

ray can be also expressed as line from a to b

pub fn is_on(&self, pos: Vect) -> bool

returns whether point belongs to the INFINITE LINE Ray expresses

pub fn within(&self, pos: Vect) -> bool

returns whether point in in AABB this raycast expresses

pub fn contains(&self, pos: Vect) -> bool

combination of within and is_on, if it returns true point belongs to a Ray

pub fn prj_x(&self, x: f32) -> f32

projects x coordinate to y coordinate. This is mainly an helper for intersection calculations

pub fn prj_y(&self, y: f32) -> f32

opposite of prj_x

pub fn project_to_grid(&self, grid_resolution: Vect) -> Self

pub fn inverted(&self) -> Self

returns ray in opposite direction
