Unity Script Reference – Vector3.Reflect

Vector3.Reflect

static function Reflect (inDirection : Vector3, inNormal : Vector3) : Vector3

Description

Reflects a vector off the plane defined by a normal.

The inNormal vector defines a plane (a plane's normal is the vector that is perpendicular to its surface). the inDirection vector is treated as a directional arrow coming in to the plane. The returned value is a vector of equal magnitude to inDirection but with its direction reflected.

Reflection of a vector off a plane.

JavaScript

    var originalObject : Transform;
    var reflectedObject : Transform;
    function Update () {
        // Makes the reflected object appear opposite of the original object,
        // mirrored along the z-axis of the world
        reflectedObject.position = Vector3.Reflect (originalObject.position, Vector3.right);
    }
