通过事件组件和代理组件对元素进行Aframe触发动画

我正在尝试在查看某个特定元素时触发其他元素上的动画。所以我想要实现的是:当我将球悬停时,文本应淡入。当我离开球时,文本应淡出。

有人告诉我aframe-proxy-event-component可以做到这一点,但是我找不到任何有关如何使用它的示例或文档。

代码看起来像这样:

<script src="https://unpkg.com/aframe-animation-component@5.1.2/dist/aframe-animation-component.min.js"></script>
<script src="https://unpkg.com/aframe-event-set-component@4.0.0/dist/aframe-event-set-component.min.js"></script>
<script src="https://unpkg.com/aframe-proxy-event-component/dist/aframe-proxy-event-component.min.js"></script>

<a-mixin id="scaleUpMixin" animation__scale="property: scale; dur: 500; easing: easeInOutQuad; to: 1.5 1.5 1.5;"></a-mixin>
<a-mixin id="scaleDownMixin" animation__scale2="property: scale; dur: 500; easing: easeInOutQuad; to: 1 1 1;"></a-mixin>

<a-mixin id="fadeInText" animation__opacity="property: text.opacity; dur: 500; to: 1"></a-mixin>
<a-mixin id="fadeOutText" animation__opacity2="property: text.opacity; dur: 500; to: 0"></a-mixin>

<a-entity rotation="0 -10 0">
    <!-- Planet -->
    <a-sphere color="yellow" position="0 1.8 -5" radius="0.5" scale="1 1 1" 
        mixin="scaleUpMixin scaleDownMixin"
        animation__scale="startEvents: mouseenter;"
        animation__scale2="startEvents: mouseleave;">
    </a-sphere>

    <!-- Text -->
    <a-text id="TextMercury" class="textbox" text="value: Merkur; align: center; color:#FFF" opacity="0" scale="0.8 0.8 0.8"
        position="0 1.8 -1"> </a-text>

</a-entity>

您需要将proxy-event组件附加到球体上。 @ github

如果有按钮,则可以重定向任何这样的事件:

<a-box proxy-event="event: event; to: targetSelector; as: newname"></a-box>
<a-entity animation="(...) startEvents: newname"></a-entity>

this fiddle中签出。
