/*************************************** *********************
* Rolling Effect
* Note: All parameters are required.
* @ Param {string} id: ID of the rolling layer to be bound
* @ Param direction {string/number} ction scroll direction top/up/0: up; bottom/down/1: down; left/2: left; right/3: right
* @ Param {number} Step rolling speed. The default value is 1. The larger the value, the slower the rolling speed.
* @ Param {number} width specifies the width of the scrolling layer. If it is set to 0, the width of the layer specified by the ID parameter is used.
* @ Param {number} height the height of the rolling layer. If it is set to 0, the height of the layer specified by the ID parameter is used.
* @ Param {number} timer rolling speed. The interval for moving 1 pixel is 30 milliseconds by default. If it is less than 20, it is 20.
* @ Param {number} delaytime the number of milliseconds between each scroll, usually 3000
* @ Param {number} waittime the number of seconds to wait before the first rolling, in milliseconds. The default value is 800. If it is less than 800, It is the default value.
* @ Param {number} The number of shards that scrollstep rolls each time
*
* @ Example
