Aframe 奇怪的触发问题

Question

编辑：-> 找到导致我的问题的原因https://github.com/aframevr/aframe/issues/3297 需要修复

('I have an strange issue. I have two scenes. When i press a button you switch to the other scene and there is another button which brings you back to the first scene. I activate the button with an click on it or an gazer(fuser). Now my Problem: when i gaze on button 1 and change the scene and then click on button 2 to come back, button 1 is already triggerd (so it changes scene again). If i just gaze on buttons or just click on them everthing works fine just when i gaze something and after that click it fails. Need some help here some code:')

Answer 1

我知道使用一个解决方法：我禁用光标并仅在 VR 模式下启用它。所以问题没有出现，但换一个结论会更好。

这样我就禁用了我的光标（也设置为 false 可见）：

document.getElementById('cursor').setAttribute('raycaster', 'objects: .notclickable');

Answer 2

如果只显示部分代码，通常更难调试。但如果我没理解错的话，你希望能够通过凝视熔断器切换伪场景。

下面是一个带有伪场景的工作示例，希望对您的用例有所帮助：

Answer 3

我建议使用数据属性或组件而不是 class，因为它们会自动获得 added/removed to/from raycaster 对象列表：

<a-cursor raycaster="objects: [data-clickable];" ... ></a-cursor>

<a-entity id="button" data-clickable ... ></a-entity>

然后只需添加和删除它：

buttonEl.setAttribute('data-clickable', '');

buttonEl.removeAttribute('data-clickable');

使用 classes，您需要使用 raycasterEl.components.raycaster.refreshObjects() 手动刷新 raycaster 对象列表。如果使用上述方法则不需要。

此问题已记录 -> https://github.com/aframevr/aframe/issues/3297。解决方法：如果你按下某个东西，整个场景和相机都会移动一些度数
