I will show you how to create a Jumping System in Unity. The hardest part is to prevent a double jump or mid air jumps. We will prevent this by a grounded check. Have fun!

private void Jump()
{

var grounded = Physics.Raycast(transform.position + Vector3.up * 0.05f, Vector3.down, 0.1f);
Debug.DrawRay(transform.position + Vector3.up * 0.05f, Vector3.down, Color.red, 0.1f);

if (JumpButton.Pressed && grounded)
{
Rigidbody.velocity = new Vector3(Rigidbody.velocity.x, JumpForce, Rigidbody.velocity.z);
Actions.Jump();
}

}
