ahora yo cambie panCamera para que se moviera constantemente el carrousel (spin += 0.01;) , lo que quiero es agregar dos botones, uno adelante y otro atras, que al dar click sobre alguno, el carrousel gire exactamente el ancho de un item del carrousel (unos 75 pixels).
yo agregue la funcion boton.onPress = function () para que al dar click comience el giro, el problema que onterframe hace que gire ya constantemente, como logro que gire solo 75 pixels o su ekivalente en frames?? espero alguien me pueda ayudar
