Hello three.js family, I have a question with drag and drop issue on Orthographic Camera. I cannot move cube on the scene. What’s my mistake? Can you help me? My codes here: [https://jsfiddle.net/h8j4auyk/8/](https://jsfiddle.net/h8j4auyk/8/)

This fiddle should now correctly print intersections to the console: [https://jsfiddle.net/2yqw4n7L/](https://jsfiddle.net/2yqw4n7L/)

The previous code produced a runtime error which was visible in the browser console. Be aware that `Projector` is no part of the core library anymore. And you don’t use it to project/unproject vectors. Instead, use the respective methods of `Vector3`.

[https://threejs.org/docs/index.html#api/en/math/Vector3.project](https://threejs.org/docs/index.html#api/en/math/Vector3.project)  
[https://threejs.org/docs/index.html#api/en/math/Vector3.unproject](https://threejs.org/docs/index.html#api/en/math/Vector3.unproject)

Ensure to work with tutorials or books which are as up-to-date as possible. Some resources refer to really old `three.js` revisions which are not recommended anymore.
