【问题描述】:
问题:
我想制作一个用户可以扔的球。使用我目前的实现,物理工作,但我无法举起球。但是,如果我删除“动态体”,我可以完全按照我的预期抓住球,然后移动它。哎呀,我尝试将其更改为“静态体”,它仍然有效。每当我混合可抓取和动态主体时,问题似乎就出现了。我知道在旧版本中应该可以,因为我正在使用本教程:https://www.youtube.com/watch?v=SKYfYd3pk4I
但是,他正在使用最新的超级手包中没有的渐进式控件,我不知道这是否会改变任何东西。我在这里做错了什么吗?
以下是我可能会影响结果的代码片段:

我的问题领域:

</a-entity>
</a-camera>
<a-entity sphere-collider="objects: .interactable" handModelStyle: lowPoly; super-hands hand-controls="hand: left"></a-entity>
<a-entity sphere-collider="objects: .interactable" handModelStyle: lowPoly; super-hands hand-controls="hand: right"></a-entity>
</a-entity>
最后,定义重力的场景:
<a-scene embedded antialias="false" physics="gravity: -9.8; debug: true">
