Question

有一个Python函数可以输出选定的背景

<a-sky ID="sky" color="{{object.background}}"></a-sky>

背景格式为“＃c6aa99”，“＃e1a600”，“＃290942”，“星级”，“城市”，“火星”。

如何使变量值等于'star'，'city'，'Mars'从<a-assets>加载图像？

 <a-scene id="aframe" foo >

      <a-assets>

Answer 1

A-Frame的documentation for A-Sky有一个很好的例子：

<a-scene>
  <a-assets>
    <img id="sky" src="sky.png">
  </a-assets>
  <a-sky src="#sky"></a-sky>
</a-scene>

对于上面的示例，您要做的是从使用color的{{1}}属性切换为使用src的{{1}}属性，并引用<a-sky>您想在天空中使用的id的属性。像这样：

<img>

如何将python变量引用到<a-assets>？
