Declaration

public static Vector2 Reflect(Vector2 inDirection, Vector2 inNormal);

Parameters

inDirection The direction vector towards the surface.
inNormal The normal vector that defines the surface.

Description

Reflects a vector off the surface defined by a normal.

This method calculates a reflected vector using the following formula: v = inDirection - 2 * inNormal * dot(inDirection inNormal). The inNormal vector defines a surface. A surface's normal is the vector that is perpendicular to its surface. The inDirection vector is treated as a directional arrow coming into the surface. The returned value is a vector of equal magnitude to inDirection but with its direction reflected.
