Time for action – creating an event

Let's create an event to fire off any time our player jumps:

1. Open up PlayerBehavior and add in the following changes:

     void FixedUpdate()
     {
         if(IsGrounded() && Input.GetKeyDown(KeyCode.Space))
         {
             _rb.AddForce(Vector3.up * jumpVelocity,
                ForceMode.Impulse);

             // 3

         }
     }

     // ... No changes needed in IsGrounded or OnCollisionEnter
 }
  

Let's break down the code:
