Unity Impact Effect Wrong Rotation

Question

Hi, I couldn't find an answer for this anywhere but I am shooting a bullet not using raycasts and instantiating an impact effect with Instantiate(concreteInpact, transform.position, Quaternion.identity); But the impact effect is always looking up.

I know that quaternion.idenity doesnt work, however I don't know what else to use.

Thanks!

You'll want to get the normal of the collision, then use something like Quaternion.LookRotation() to make the impact face in that direction instead of Quaternion.identity.

Thanks I will try that out! But what does getting the normal do? Like what does normal mean?

A normal is just a line that's perpendicular to another line, drew something really quickly in paint, where the red line is the normal to the black line and vice versa, to make it easier to visualise.

To get it, if you're using OnCollisionEnter(Collision other), you could use other.contacts[0].normal and that would give you the normal to your collision as a Vector3.
