Can someone help me?

Unity Engine
1

so I found this code online, and its kind of what I was looking for because I needed a roll a ball player controller that worked, I was hoping someone could let me know what I need to add to make it so I can change the speed of the ball as a variable at will.

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour
{

    public Rigidbody rb;

    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void FixedUpdate()
    {
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0, moveVertical);

        rb.AddForce(movement);
    }
}

also yes I am new to unity

Just add a public field to control the speed of the ball. That will allow you to set the speed both in the Inspector in the Editor, and through scripting:

using UnityEngine;
using System.Collections;
public class PlayerController : MonoBehaviour
{
    public float pushingForce = 1f;

    public Rigidbody rb;
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }
    void FixedUpdate()
    {
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");
        Vector3 movement = new Vector3(moveHorizontal, 0, moveVertical);
        rb.AddForce(movement * pushingForce);
    }
}

Be aware though that using AddForce in this way will let the player continually add speed to your object without a reasonable limit.
