如何解决Three.js THREE.DeviceOrientationControls不是构造函数
ThreeJS给我此错误消息时遇到了问题。我包括了所有必需的ThreeJS文件,但仍然出现此消息。我的意图是让移动设备使用DeviceOrientationControl.js导航。 Mousemove的效果很好,但是我无法使它正常工作。有什么想法吗?

解决方法
通过ES6模块导入诸如DeviceOrientationControls
之类的示例文件时,不再需要使用THREE
名称空间。所以代替
controls = new THREE.DeviceOrientationControls(camera);
使用
controls = new DeviceOrientationControls(camera);
