Javascript A帧动画
我尝试了太多,但结果相同,当自定义事件触发a帧中的动画时,它以相同的方式播放该动画,从(x,y,z)到(x',y',z'),从(x',y',z')到(x',y',z')) 我使用了a动画属性,但从未找到解决方案Javascript A帧动画,javascript,aframe,Javascript,Aframe,我尝试了太多,但结果相同,当自定义事件触发a帧中的动画时,它以相同的方式播放该动画,从(x,y,z)到(x',y',z'),从(x',y',z')到(x',y',z')) 我使用了a动画属性,但从未找到解决方案 <html> <body> <script src="https://aframe.io/releases/0.2.0/aframe.min.js"><

以下是codepen中的测试:
这里的部分问题是,点击被反复触发。我们可以这样控制:
var at = "one";
one.addEventListener('click', function () {
if( at !== "one") {
at = "one";
camera.emit('one');
}
});
two.addEventListener('click', function () {
if( at !== "two") {
at = "two";
camera.emit('two');
}
});
three.addEventListener('click', function () {
if( at !== "three") {
at = "three";
camera.emit('three');
}
});
你的目标是什么?看起来您的项目似乎正常工作,当您查看每个对象时,您会看到动画。问题是当我查看上一个对象时,相机会从上一个对象移动到当前对象,而不是反向移动(我希望它从当前位置移动到上一个对象位置)当我看前一个对象时,它会捕捉到视图中的中心…问题是动画只在一个方向上从一个移动到两个,或者从两个移动到三个-没有反向动画。此外,动画会不断调用,因为您一直在查看(/单击)其中一个平面,该平面会触发向后跳转和向前跳转。(不幸的是,我不知道解决这个问题的最佳方法。)或者,增加光标上的
