Three.js THREE.DeviceOrientationControls不是构造函数

问题描述

ThreeJS在给我此错误消息时遇到问题.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进行导航.Mousemove的效果很好，但我无法使它正常工作.有什么想法吗?

I have a problem with ThreeJS giving me this error message. I included all the necessary ThreeJS files but still this message appears. My intention is to have a mobile device navigating with DeviceOrientationControl.js. Mousemove works very well, but I can't get this to work. Any ideas?

Uncaught TypeError: THREE.DeviceOrientationControls is not a constructor

推荐答案

通过ES6模块导入 DeviceOrientationControls 之类的示例文件时，不再需要使用 THREE 命名空间.因此，而不是

When importing examples files like DeviceOrientationControls via ES6 modules, using the THREE namespace is not necessary anymore. So instead of

controls = new THREE.DeviceOrientationControls(camera);

使用

controls = new DeviceOrientationControls(camera);
