Extending slider prototype, override any function

To override any function without modifying slider core - you may extend they prototype.

Let's assume that you need to know when slider autoplay has stopped permanently. There is public function stopAutoPlay, let's extend it.

jQuery(document).ready(function($) {
    // initialize slider as usual and save it's object
    var slider = $('.royalSlider').royalSlider({
        // options
    }).data('royalSlider');

    // extend slider object
    slider.stopAutoPlay = function( /* optional_arguments */  ) {
        // do something there    
        console.log('slideshow is permanently stopped');
        
        $.rsProto.stopAutoPlay.call(this /* , optional_arguments */ );
    };

});

jQuery.rsProto - public variable that holds slider prototype, log it to see what functions do you have. You can extend only public functions. Functions that start from underscore _ may be renamed in build process.
