如何在随机位置产生多个球体[a-frame]

Question

在// Parse message body env, _ := enmime.ReadEnvelope(r) // Headers can be retrieved via Envelope.GetHeader(name). fmt.Printf("From: %v\n", env.GetHeader("From")) // Address-type headers can be parsed into a list of decoded mail.Address structs. alist, _ := env.AddressList("To") for _, addr := range alist { fmt.Printf("To: %s <%s>\n", addr.Name, addr.Address) } fmt.Printf("Subject: %v\n", env.GetHeader("Subject")) // The plain text body is available as mime.Text. fmt.Printf("Text Body: %v chars\n", len(env.Text)) // The HTML body is stored in mime.HTML. fmt.Printf("HTML Body: %v chars\n", len(env.HTML)) // mime.Inlines is a slice of inlined attacments. fmt.Printf("Inlines: %v\n", len(env.Inlines)) // mime.Attachments contains the non-inline attachments. fmt.Printf("Attachments: %v\n", len(env.Attachments)) 中，我希望产生aframe 100次，每次都是随机sphere

首先，position中的每个值都应该是-100到100之间的数字

position= "x y z"

其次，上面的代码应重复100次，使之前的<a-sphere position="x y z" radius="0.5"> </a-sphere> 不受影响。

这是所需的end result，忽略了动作。

如何实现这一目标？

使用entity-generator + randomizer组件。

<a-mixin id="sphere" geometry="primitive: sphere" material random-position="min: -100 -100 -100; max: 100 100 100"></a-mixin>
<a-entity entity-generator="mixin: sphere; num: 100"></a-entity>
