WebbThen I call a Physics2D.BoxCast: var hit = Physics2D.BoxCast (new Vector2 (0, 2), new Vector2 (1, 1), 0, new Vector2 (0, -1)); It is a Box Ray Cast like the following pic: I have a hit returned. But hit.distance == 0.9950001, which is supposed to be 1. I guess there may be some inaccuracy in Physics2D.BoxCast.

WebbThe normal vector of the surface hit by the ray. The normal vector of a surface is the vector that points outward perpendicularly at a given point on that surface. This vector can be useful in raycasting as a way to determine reflections or ricochets from projectiles or to align a character so that it stands upright on the surface.
