如何在A帧场景初始化/加载时延迟/延迟/控制? [英] How do I delay/defer/control when an A-Frame scene initializes/loads?

问题描述

我想让A帧场景仅在通知时才开始加载.目前，如果我将<a-scene>放在HTML文件中，它将立即开始初始化.

I want to have an A-Frame scene start loading only when I tell it to. Currently if I put <a-scene> in an HTML file, it will start initializing immediately.

<a-scene></a-scene>

推荐答案

A帧场景在其自身初始化之前会等待其所有子代初始化.因此，它从下至上等待每个<a-entity>.在引擎盖下，<a-entity>基于处理装载顺序的<a-node>.当<a-node>发出loaded时，父节点即可开始加载. <a-entity>在附加+初始化其所有组件时发出loaded.

An A-Frame scene waits for all of its children to initialize before it itself initializes. So it waits for every <a-entity> from the bottom up. Under the hood, <a-entity> is based on <a-node> which handles load order. When <a-node> emits loaded, then the parent nodes can begin loading. <a-entity> emits loaded when it attaches + initializes all of its components.

因此，您可以按需启动场景:

Therefore, you start a scene on demand:

<a-scene>
  <a-node id="waitOnMe"></a-node>
</a-scene>

document.getElementById('waitOnMe').emit('loaded');  // When you are ready.
