求做一个按键精灵鼠标上下滑动的脚本
UserVar sx=100 “首X坐标”
UserVar sy=100 “首Y坐标”
UserVar ex=300 “尾X坐标”
UserVar ey=300 “尾y坐标”
UserVar yc=5 “延迟”
MoveTo sx, sy
//RightDown 1 //使用时，请自己取消注释！
tx = ex – sx
ty = ey – sy
If tx = ty Then
ci = ty
tx = tx / ty
ty = ty / ty
Else
ci = tx
tx = tx / tx
ty = ty / tx
End If
do
For i = 1 To ci
Moveto sx+tx*i*(-1)^n, sy+ty*i*(-1)^n
Delay yc
Next
GetCursorPos x, y
sx = x
sy = y
If n = 0 Then
n = 1
Else
n = 0
End If

博客地址：
@jQuery or @String box : 滚动列表jQuery对象或者选择器 如：滚动元素为li的外层ul
@object config : {
@Number width : 一次滚动宽度，默认为box里面第一个一级子元素宽度[如果子元素宽度不均匀则滚动效果会错乱]
@Number size : 列表长度，默认为box里面所有一级子元素个数[如果size不等于一级子元素个数，则不支持循环滚动]
@Boolean loop : 是否支持循环滚动 默认 true
@Boolean auto : 是否自动滚动,支持自动滚动时必须支持循环滚动，否则设置无效,默认为true
@Number auto_wait_time : 自动轮播一次时间间隔,默认为：3000ms
@Function callback : 滚动完回调函数，参入一个参数当前滚动节点索引值

谁给我发一下让屏幕上下不停滑动的auto.js的脚本？
这几行脚本会先下滑在上滑停两秒在重复
“auto”;
while (true) {
swipe(device.width / 2, 800, device.width / 2, 500, 2000);
swipe(device.width / 2, 500, device.width / 2, 800, 2000);
sleep(2000)
}
