Is there a replacement for this type?

Question

Unity

The question is a little silly, but is there an alternative for this line with only Rigidbody2D

GetComponent<Rigidbody>().rotation = (Quaternion) stream.ReceiveNext();

Answer 1

can be done like this:

Rigidbody rb;

void Start():
    rb = GetComponent<Rigidbody>()

and in code:
rb.rotation = (Quaternion) stream.ReceiveNext();
