有沒有辦法以更漂亮的方式重用相同的動畫?如何在A幀中重用動畫?
<a-entity channel-selection class="channels" mixin="fontplane" material="opacity:0.6">
<a-animation attribute="material.opacity" begin="fade" to="0"></a-animation>
<a-animation attribute="material.opacity" begin="unfade" to="0.6"></a-animation>
<a-entity class="channels" mixin="channelfont" text="text: Channel6">
<a-animation attribute="material.opacity" begin="fade" to="0"></a-animation>
<a-animation attribute="material.opacity" begin="unfade" to="0.6"></a-animation>
</a-entity>
