AFrame：物理问题； dynamic-body & 可抓取

Question

问题：

我想制作一个用户可以扔的球。在我目前的实施中，物理可以工作，但我不能举起球。但是，如果我删除“dynamic-body”，我就可以准确地抓住球，然后四处移动。哎呀，我试着把它改成“static-body”，它仍然有效。问题似乎是每当我将 grabbable 和 dynamic-body 混合使用时。我知道在旧版本中应该是可能的，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 super-hands 软件包中没有的 progressive-controls，我不知道这是否会改变什么。我这里有什么地方做错了吗？

以下是我可能会影响结果的代码片段：

          </a-entity>

最后，a-scene定义引力：

<a-scene embedded antialias="false" physics="gravity: -9.8; debug: true">

Answer 1

多亏了这个：https://github.com/bryik/aframe-ball-throw/blob/master/index.html

我找到了罪魁祸首。我需要将静态体添加到我的手实体中，以便可以检测到碰撞。不知道为什么之前没有它们会检测到碰撞。

修改后的代码：

        <a-entity static-body="shape: sphere; sphereRadius: 0.02;" sphere-collider="objects: .interactable" handModelStyle: lowPoly; super-hands hand-controls="hand: left"></a-entity>
        <a-entity static-body="shape: sphere; sphereRadius: 0.02;" sphere-collider="objects: .interactable" handModelStyle: lowPoly; super-hands hand-controls="hand: right"></a-entity>
