How can I acces in PlayerMovement.cs that RigidBody? How can I find it?

Thanks!

You get a reference to it.

Since you have the PlayerMovement component on the same game object, GetComponent is your friend.

If you are able to store the reference in a field(variable) then you can reuse it has the script is called over and over again.

example in start(c#):

using System;
using UnityEngine;

public class HeadBob : MonoBehaviour
{
	private Rigidbody2D myScriptsRigidbody2D;
	
	void Start()
	{
		myScriptsRigidbody2D = GetComponent<Rigidbody2D>();
	}
	
	void Update()
	{
		myScriptsRigidbody2D.AddForce(new Vector3(6, 8, 1)); // just an example.
	}
}

example in start(java/unityscript)

private myScriptsRigidbody2D : Rigidbody2D;

function Start()
{
	myScriptsRigidbody2D = GetComponent.<Rigidbody2D>();
}

function Update()
{
	myScriptsRigidbody2D.AddForce(Vector3(6, 8, 1)) // just an example.
}
