Cuando se produce un cambio de estado del personaje, al presionar una tecla, NO se produce el cambio de animacion corespondiente a ese estado, no se si esta claro lo que pregunto.
Por las dudas pueden correr el codigo ustedes:
(la imagen debe estar en la carppeta "data" y el script en el mismo directorio que "data")

Desde ya les estare muy agradecido por la ayuda.
