My character won't move

Question

I am very new to Unity and C# and I was following a simple tutorial (2-3 years old) I used the exact same code as they did but the player (a ball) won't even move left and right. Here is the script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 public class AddPlayerControlledVelocity : MonoBehaviour
 {
     [SerializeField]
     Vector3 v3Force;
     
     [SerializeField]
     KeyCode keypositive;
     [SerializeField]
     KeyCode keynegative;
     void FixedUpdate()
     {
         if (Input.GetKey(keypositive))
             GetComponent<Rigidbody>().velocity += v3Force;
         
         if (Input.GetKey(keypositive))
             GetComponent<Rigidbody>().velocity -= v3Force;
     }

At first glance it seems like you have accidentally written out the following code twice: if (Input.GetKey(keypositive)) GetComponent().velocity += v3Force;

as a result of t$$anonymous$$s, when you press the key set as positive not$$anonymous$$ng happens as they cancel each other out w$$anonymous$$le pressing the negative key also does not$$anonymous$$ng as it isn't scripted to do anyt$$anonymous$$ng.

Just change the second one of the code mentioned above to: if(Input.GetKey(keynegative)) It should work! Hope that helps! ^-^
