我一直在研究这个问题已经有一段时间了,但似乎找不到解决方法。
我正在尝试构建一个水平滚轮模块(由“图层”数组组成),在屏幕中间有一个“选择器”图层,用于选择落在其上的所述阵列中的图层,显示所述图层的名称以及与之关联的页面。 换句话说,一旦“米色层”落在“选择器”上,this.name将显示在this.layer下方,“米色页面”.x = 0
现在的问题是轮子只在onDrag上移动,所以你必须继续拖动它才能移动而不是onScroll。我已经尝试过阅读相关于“selector”的“layers”数组中的图层的x位置并触发命令,我也尝试使用页面的.parent属性,但它不起作用应该的方式。
如果有帮助,这是一个框架链接,http://share.framerjs.com/psbqx3dvqtz9/
任何帮助都会受到赞赏,伙计们。
提前致谢!

我认为您可以使用onMove
代替onDrag
来实现您尝试做的事情。这将在拖动和动画期间触发,因此您也可以获得滚动的速度。
因为你在一个圆圈中滚动,所以滚动应该是无限的。这可以通过在每次移动中设置x
来模拟滚动组件的宽度来实现。可以找到一个例子here。
要将此应用于您的代码,您需要进行一些更改:
onMove
代替onDrag
@x
中的onMove
,如下所示:@x = start + @x % scroll.width
onDragEnd
代码这导致以下代码:

circleCenterZ=0
circleCenterX= Screen.width / 2
circleRadius= 500
scrollSensitivity= 50
depthOfField= 25
