Question by KalibooStew · Jul 12, 2014 at 08:11 PM · 2dphysicscolliderangle

Calculate the normal of a collider

I have a 2D game with two objects - the player (a circle) and rectangle (which can be rotated at any angle). The player can collide with this rectangle.

How can I calculate the normal line of the collider (by which I mean the angle at which the player hits the rectangle)?

Thanks

You don't need to calculate it - it's given to you in the Collision2D object passed to OnCollisionEnter2D: http://docs.unity3d.com/ScriptReference/ContactPoint2D-normal.html
