Question by BenjaminWayra · Dec 24, 2019 at 01:15 PM · vector3mathfreflect

I don't understand how to use Vector3.reflect in Unity2D

I need to create a Ricochet effect between a bullet and a shield. I don't understand if I have to use this in my bullet or my shield I don't understand what does inDirection take in.

In general I already looked at the forums and I still don't understand. Help is appreciated.

The drawing in the documentation looks pretty clear:

I am talking about if it takes direction or velocity, how to reference it and also how to change speed

inDirection can be a direction or a velocity.

If you want to decrease the velocity after impact, multiply the output vector by a "deceleration" factor (0.95f for instance)

you can use like this "Vector2.Reflect(v1,v2)" v1 means the move direction of bullet and v2 means a Vector which is perpenticular to your shield surface

How can I get the normal of my shield, which would be v2?
