How to use the OnCollisionStay2D function on another object?

Question

2D

the question seems to be simple.
here is the script.
public void OnCollisionStay2D(Collision2D other)
{
if ( I = 1 )
{
if (other.transform.tag == "Ground") {
OnGround = true;
}
}
if(other.transform.tag == "Ground")
{
//OnGround = true;
body.drag = 10;
jump = true;
}
}
Function works on object on which the script hangs, and it is necessary for me that it was possible to work with another without multiplying scripts.

Answer 1

To answer the question directly, no.
OnCollisionStay2D is called for the object on which the script containing it hangs. As well as other MonoBehaviour functions - Update, Awake and more.
