Ignoring by the player of the platform provided?

Question

C++ / C#

I'm new to C#, I need the player to ignore it while flying through the platform from below, but stuck at this moment

if (rb.velocity.y > 0)
                {
                    Physics2D.IgnoreCollision();
                }

how to insert the elements there

Answer 1

Well, there is Platform Effector2d , which will make it possible to shed from below. And why do you need it to get stuck in the platform?
