    hello, tell me, is it possible to get this collider from an object that hit the collider in Unity?
    That is, Collider A collides with Collider B, and A gets information about Collider B.
    Sorry for the translation, I hope you understand what I mean.

    Yes the collision callbacks (OnCollisionEnter, OnTriggerEnter, OnCollisionEnter2D, OnTriggerEnter2D) all contain information about the other object in the parameters provided to the method.

    Thanks for the help, but the question arose: Can OnTrigger work without a rigidbody ?
    I'm making a 2D game and don't use rigidbody

    If you look at the charts at the bottom of https://docs.unity3d.com/Manual/CollidersOverview.html you will see the conditions under which trigger messages will be sent.

    Short answer is you need at least one Rigidbody. It can be kinematic though.
