Vector3.Reflect

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.

	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);
	}
