Hey,

I've got some code which allows me to fire some projectiles, but i'm struggling to find appropriate code or maths to handle the collision / deflection. Saying that I can find certain code / maths for colliding with other rigid bodies, but I only want to deflect off a static floor.

I technically know that the output angle will be the input angle reflected along the surface normal (calculating this isn't a problem), as shown here:

But i'm after understanding how to calculate in CoR (bounce) and spin (Magnus), friction, etc...

Either code or good resources welcome ;)
