How to reflect rays on hit

Reflecting rays using raycasting Want bullets to ricochet? Lasers to bounce? Custom Pong game? Here’s a simple way to reflect a ray when it hits a surface using the surface normal returned by the Raycast method! Formula We will be working with this equation: r = d - 2(d ⋅ n)n Where r is the resultant reflection normal, d is the normal of our ray, and n is the surface normal that our ray hit (We will get n from the RaycastResult that the Raycast method returns). Because we are doing reflec…
