Ray2 class

A ray in the 2d plane.

The direction should be normalized.

Constructors

Ray2({required Vector2 origin, required Vector2 direction})

Ray2.zero()

Properties

Methods

clone() → Ray2

Deep clones the object, i.e. both origin and direction are cloned into a new Ray2 object.

intersectsWithAabb2(Aabb2 box) → bool

Whether the ray intersects the box or not.

lineSegmentIntersection(LineSegment segment) → double?

Returns where (length wise) on the ray that the ray intersects the LineSegment or null if there is no intersection.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

point(double length, {Vector2? out}) → Vector2

Gives the point at a certain length along the ray.

setFrom(Ray2 other) → void

Sets the values by copying them from other.

setWith({required Vector2 origin, required Vector2 direction}) → void

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
