Public Constructors

public Ray ()

Create a ray with an origin of (0,0,0) and a direction of Vector3.forward().

public Ray (Vector3 origin, Vector3 direction)

Create a ray with a specified origin and direction. The direction will automatically be normalized.

Parameters

origin	the ray's origin
direction	the ray's direction

Public Methods

public Vector3 getDirection ()

Get the direction of the ray.

Returns

• a new vector that represents the ray's direction

public Vector3 getOrigin ()

Get the origin of the ray.

Returns

• a new vector that represents the ray's origin

public Vector3 getPoint (float distance)

Get a point at a distance along the ray.

Parameters

distance	distance along the ray of the point

Returns

• a new vector that represents a point at a distance along the ray.

public void setDirection (Vector3 direction)

Set the direction of the ray. The direction will automatically be normalized.

Parameters

direction	the new direction of the ray

public void setOrigin (Vector3 origin)

Set the origin of the ray in world coordinates.

Parameters

origin	the new origin of the ray.
