scripting fail... help

while trying to create a character controller for 2d i got the following errors on the script

using UnityEngine;
using System.Collections;
public class wellhullothere : MonoBehaviour
{
public float maxSpeed = 10f;
readonly bool facingRight = true;
void Start()
{
}
void FixedUpdate()
{
float move = Input.GetAxisRaw("Horizontal");
Rigidbody2D.Velocity = new Vector2(move * maxSpeed, Rigidbody2D.Velocity.y); (error: ´Rigidbody2d doesen´t contain a definition for ´velocity´)
if (move < 0 && !facingRight)
Flip ();
else if (move > 0 && facingRight)
Flip ();
}
private void Flip()
{
facingRight = !facingRight; (error: a only reading field cannot be assigned)
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
} }
anybody can help?

 

First of all, it is probably "v"elocity.y without a capital. Second of all, I believe you need to remove the readonly part of the bool.

 

welp… i failed
thank you so much!
