如何停止 mapbox-gl.js 跟踪我的移动指南针

Question

当我在手机上使用 mapbox-gl.js 地图时 phone 它会在我转动手机时一直旋转 phone 以保持北方。我怎样才能阻止这个？我确实希望继续能够使用触摸手势旋转地图...

这里是 api.

嗯...，抱歉，方位跟踪目前不在 mapbox-gl.js api 中。这是 'my own' 代码。我从某处调整并忘记了......的片段：

  const easing = t => t * (2 - t)

  if (window.DeviceOrientationEvent) {
    window.addEventListener('deviceorientation', event => {
      let compassdir
      if (event.webkitCompassHeading) {
        // Apple works only with this, alpha doesn't work
        compassdir = event.webkitCompassHeading
      }
      else {
        compassdir = event.alpha
      }
      myMap.easeTo({
        bearing: 360 - compassdir,
        easing: easing
      })
    })
  }
  else {
    alert("Sorry, your browser doesn't support Device Orientation")
  }
