Ray

非推奨を表示

The Ray data type represents a half-line, finite in one direction but infinite in the other. It can be defined by a 3D point, where the line originates from, and a direction vector, which is the direction it goes in.

プロパティ

Unit

Ray

The Ray with a normalized direction (the direction has a magnitude of 1).

Origin

Vector3

The position of the origin.

Direction

Vector3

The direction vector of the Ray.

方法

ClosestPoint

Vector3

Returns a Vector3 projected onto the ray so that it is within the Ray line of sight.

Note: the Ray must be a unit ray for this method to behave as expected!
