PASO 7: Podemos ver a nuestro jugador en el escenario ahora, pero necesitamos devolver el sprite de add_player() para poder usar el sprite en nuestra función main() .
La declaración de retorno pasa una variable de una función de regreso a donde se llama la función.
Haga clic en LÓGICA. Ir a y arrastre Return Statement a la última línea de add_player() .
Cambie la variable que se devuelve de my_var a player . ¡Asegúrese de que esta declaración de devolución esté sangrada!
