The tutorial：
The engine will automatically get the Animation component on the Body node and assign it to BodyAnim. As a result, the PlayerController's BodyAnim property references the Animation component of Body node.

My case

1. The "Body Anim" is null at the begining, and I have to create it.
2. After clicking the blue "Create" btn, I cannot drag anything to it. To be more accurate, I can do NOTHING with it, its blank.

TypeScript and Cocos Engine both have Animation classes.
So, please ensure the Animation class has been imported by import { ... } from 'cc, or it will use the Animation class from the TypeScript package.
