Time for action – pressing the spacebar to jump!

Now that we have a basic grasp of enumeration types, we can capture keyboard input using the KeyCode enum.

Update PlayerBehavior with the following code, save, and hit Play:

public class PlayerBehavior : MonoBehaviour 
 {
    public float moveSpeed = 10f;
    public float rotateSpeed = 75f;
 
     // 1
     public float jumpVelocity = 5f;
 
     private float vInput;
     private float hInput;
 
     private Rigidbody _rb;
 
     void Start()
     {
         _rb = GetComponentRigidbody>();
     }
 
     void Update()
     {
         // ... No changes needed ...
     }
 
     void FixedUpdate()
     {
         // 2
         if(Input.GetKeyDown(KeyCode.Space))
         {
             // 3
             _rb.AddForce(Vector3.up * jumpVelocity, ForceMode.Impulse);
         }

         // ... No other changes needed ...
     }
 }

Let's break down this code, as follows:

1. We create a new variable to hold the amount of applied jump force we...
