1. 首先，在小程序适配触控事件需要参考小程序导出文档适配。
2. 在第一步的基础上，通过 pointer 对象的 deltaPosition 来监听本帧或者这几帧的移动。
3. 根据业务的诉求，结合几帧触控的位移，判断是否左滑右滑。

可参考示例代码：

class TouchControl extends Script {
     onUpdate() {
          const pointers = engine.inputManager.pointers;
          if(pointers && pointers.length > 0) {
                // 触控点在本帧的位置移动  pointers[0].deltaPosition
         }
     }
}
